*A reader picking a bookmaker by the size of its welcome offer is paying for the privilege of doing so. Every “enhanced odds” banner, every “£40 in free bets when you bet £20” headline, every “100% bonus” pitch on a sportsbook home page comes dressed as a gift. The Commission has spent the past two years turning that pitch into a measurable contract, and since 19 January 2026 the contract has a hard ceiling on it. This page is for the bettor who has noticed the gap between what an offer says and what it asks back.*

Data current as of 27 October 2026 and checked against the Gambling Commission’s public register of Great Britain operating licences.

Statute first: what an enhanced odds offer is allowed to cost

A price in the bettor’s head is one number. The price on the slip is another, and the gap between them is the bookmaker’s margin — the cut the operator keeps on every market. The Commission cannot dictate that margin. What it can dictate, and did with effect from 19 January 2026, is the price of the bonus that is meant to pull a new customer through the door.

Wagering requirements on bonuses are capped at ten times the bonus value for any online operator licensed for Great Britain. Mixed-product promotions — an offer that requires gambling on two or more product types, for example a sportsbook free bet tied to a casino spin package — are banned. The day the rule landed, several welcome offers across the GB market had to be rewritten because their numbers exceeded 10x, and several more had to be stripped of their casino arm because that arm dragged the sports side into the prohibited mix.

Where the rule stops. The 10x cap covers bonuses and the wagering attached to them. It does not plainly state whether free bets with no wagering condition — the kind Sky Bet issues as three £10 bet credits and BetMGM issues as four £10 bet credits on accas, the kind BoyleSports issues in pounds on the back of a £10 opening bet — sit inside it. Research has not pinned that down and neither has the Commission in published guidance. Each operator’s own terms state it, which means the bettor reads those terms, not the cap.

What a 10x cap looks like in pounds. A £10 bonus with 50x wagering — the pre-2026 ceiling on aggressive offers — meant £500 worth of betting to clear. After the cap, the same £10 bonus is settled against at most £100 of qualifying bets, and qualifying conditions are dictated by the operator (a minimum odds line, an expiry in days, the markets the bonus can be used on). The natural effect of the cap is that bonuses shrink toward £10, £20, £40, and the rollover attached to each one stops compounding into work.

What “wagering” means in this context. The bettor places a qualifying bet of a stated stake at minimum odds of a stated price; the operator counts the stake (or, on some promotions, only the win) toward the turnover it requires. The minimum price is the floor below which a bet does not count toward rollover: BoyleSports’ Acca Insurance requires minimum odds of 1/2 for the qualifying stake, and Spreadex’s free-bet offer uses the same 1/2 minimum on the qualifying fixed-odds bet. William Hill’s Football Acca Boost, by contrast, is an enhancer rather than a bonus — it pays an extra percentage on top of accumulator winnings without requiring any turnover, and each leg of the acca has to be priced at 1/5 or bigger to qualify.

Why the cap mattered. Welcome offers had drifted toward pitches that asked a customer to bet ten, twenty, fifty times the bonus value before any winnings could be withdrawn. The arithmetic of clearing those offers, measured against the margin sitting inside the bets used to clear them, was that the average customer lost more by clearing than by walking away. The 10x cap draws a line at a multiple at which that loss-by-clearing pattern stops being the rational outcome, and replaces it with an offer whose clearance the bettor can finish without subsidising the bookmaker.

Bonus terms that still vary by operator. Three remain variable and are not policed by the cap: the minimum odds on a qualifying bet, the expiry window on the free bet, and whether the stake is returned alongside the win. Coral’s free bets issued under the welcome offer expire 7 days after issue. Sky Bet’s three £10 free bet tokens and BetMGM’s four £10 free bet tokens are valid for 7 days. Spreadex issues £60 in free bets usable across fixed-odds and spread betting products once a customer has placed the qualifying bet within 28 days. The days matter: a bonus that has to be cleared in a week is a different cost from a bonus whose qualifying bet can be set down for a month.

Cash, free bet, or “boost”. The Commission limits apply to bonuses. They do not reach cashback offers, price boosts, or acca insurance that pays out as a free bet on the loss of a small stake. Coral’s Odds Booster on hundreds of markets, BoyleSports’ Acca Loyalty paid in free bets on qualifying accas, Kwiff’s Supercharge that lifts a price from 2/1 to 20/1 on individual bets — none of these carries a 10x turnover condition, and none is governed by the cap. They sit on the operator’s own terms, and the punter reads those terms for the same reason the bettor reads anything: because no offer is described by its headline alone.

Staking limits, identity checks, and what licensed play looks like

A licensed bookmaker is not the only kind of bookmaker operating online, but it is the only one bound by the LCCP, the Remote Technical Standards, the GAMSTOP requirement and the financial-vulnerability check that runs on the back of a £150 rolling 30-day deposit threshold. Each of those is a customer-facing rule, not an internal operator policy.

Identity before the first deposit. Since 7 May 2019 every licensed GB operator verifies name, address and date of birth before letting a customer put money in or place a bet — including a bet made with a free bet or bonus. The check is in-house (passport, driving licence, identity document) or through a third party. Anonymous play at a licensed site no longer exists; it died with the rule. Customers who do not pass verification cannot deposit, cannot use a free bet, and cannot withdraw.

Deposit limits at the customer’s choice. Operators offer gross deposit limits on fixed time frames — daily, weekly, monthly — that the customer sets. The first round of mandatory changes took effect on 31 October 2025. A second phase has been scheduled for 30 September 2026+, but whether it has gone live yet is not established, and a bettor reading this in 2026 should treat the second phase as announced rather than active. There is no state-set ceiling: the customer picks the figure, the operator enforces it, and the limit survives a marketing push, a bonus chase or a bad run.

The financial-vulnerability check. From 30 August 2024 licensed remote bookmakers run a public-record vulnerability check when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days — that is, the check fires on net spending, not on gross turnover. The check looks at public records such as bankruptcy orders and county court judgments. It is not a credit-reference check and it is not an income check. The Commission announced a staged plan on 7 July 2026 to extend this into formal financial risk assessments, with no start date; treat that as a future change, not a current rule.

GAMSTOP and self-exclusion. GAMSTOP is the national multi-operator self-exclusion scheme. Every GB-licensed operator offering online play is a member, and the membership is mandatory: a customer who has self-excluded through GAMSTOP cannot deposit or bet at any participating site for the duration of the exclusion. Periods are six months, one year, five years, or five years with auto-renewal. After the minimum period ends, the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP covers online channels only: betting shops run a separate offline self-exclusion.

Help on a bad run. GamCare runs the National Gambling Helpline. GambleAware funds treatment and education. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs peer-support meetings. None of these is a regulator: they are the routes a bettor takes when the limits have stopped working, and the routes an operator’s safer-gambling page should list (DAZN Bet’s safer-gambling page lists them on its account-level limits tool, alongside GamCare contact details).

Why the licensed path has its own cost. Verification feels like friction to a bettor who has used an unlicensed site. It does: that is the cost. In return, the customer gets a dispute route (IBAS-approved alternative dispute resolution is a licence condition), a Commission complaints path, GAMSTOP coverage, the bonus cap’s protection, and the vulnerability check on net spending above £150. None of those exists at an unlicensed brand. That trade is the substance of the licence; describing it without taking a position would skip over the very thing a reader is comparing brands on.

How an enhanced odds offer clears — and what it costs to clear it

A bettor reading Coral’s “£40 in free bets when you bet £20” headline sees the £40 first and the £20 second. The arithmetic that decides whether the offer is worth taking lives elsewhere. This section walks through it so the offer can be read the way it has to be read.

The offer, in its plain terms. Deposit and place a sports bet of £20 or more at minimum odds of 2.0 (1/1); the operator credits £40 in free bets within 7 days; the free bets expire 7 days after issue. The free bet is a bet credit, not a cash bonus: if the bet wins, the stake is not returned. The minimum odds on a qualifying bet are 2.0 (1/1). The free bets are paid as a single bundle of credited tokens; the bettor uses them on any market they carry.

Stated as the operator states it, the headline reads as a 100% match on a £20 bet. It is not. The bet credit, on a winning free bet at minimum odds of 2.0, returns £40 of winnings (the £20 stake is not paid back on a free bet by default). The breakeven point on a free-bet portion is the probability of winning multiplied by the winnings minus the probability of losing; expressed another way, the value of a free bet whose stake is not returned is free-bet amount × (odds − 1) ÷ odds × payout share of the market. That is the average value, not the maximum.

The bettor has to place the qualifying £20 bet at minimum odds of 2.0 (1/1). At minimum odds of 2.0 on a typical outright market (margin of roughly 5%), the £20 has an expected cost to the bettor of about £1 — the bookmaker keeps roughly 5% of the stake on average across the lifetime of the bet. On a tighter market or a less-favoured selection the expected cost rises; on a stronger favourite at longer odds it falls. The cost of the qualifying bet, against which the free bet returns its average value, sits in that range. What the bet gets out, on average, is the value of the free bet on a winning market minus the expected cost of the qualifying bet. The exact figure depends on the market the free bet is used on; the order of magnitude is what the bettor reasons about.

What the cap changes. The £40 in free bets has no wagering requirement. It is not a cash bonus on which 10x turnover is required before withdrawal. If the free bet wins, the winnings are paid as cash — the customer can withdraw them as soon as the bet settles, subject to normal identity and payment-method checks. The headline offer at Coral does not exceed the 10x cap because it is structured as a free-bet grant, not as a cash bonus with rollover. That is the structure most welcome offers in the GB market settled into after January 2026: smaller cash bonuses (where £10–£40 of bonus has been the typical grant) and free-bet grants with no rollover attached, because the rollover is the surface the cap lands on.

What the cap forbids. An offer that ran as a £40 cash bonus with 5x turnover would be £200 of betting on the bonus. At 10x it would be £400, and any larger turnover on a £40 base is forbidden — a £40 cash bonus with 15x turnover would be illegal for a GB-licensed operator. The contrast with the pre-2026 aggressive offers is the point: those often pushed 50x on a £10 bonus. The new rule prevents that structure, and the offers now marketed on GB sites have re-priced around it. Where a brand still writes a cash bonus into its welcome, the bonus is smaller and the rollover is no more than 10x; where the bonus is a free bet, no rollover applies.

The expiry window. Coral’s 7-day expiry is at the short end of what the GB market offers. Spreadex’s offer to qualify the £60 free-bet grant runs the qualifying bet window over 28 days — a long window in which to place one £10 qualifying bet. BetMGM’s four £10 free bet tokens expire 7 days from credit. Sky Bet’s three £10 free bet tokens expire 7 days from credit. QuinnBet’s free bets are valid for 7 days from credit on minimum odds of 1/2 (1.5) and maximum odds of 50/1. A 7-day expiry is workable for a customer who bets through the weekend; it is a problem for a customer who only bets on specific fixtures. The bettor matches the expiry to the fixture calendar they actually bet from.

What this means for the choice between two offers. The £40 from Coral on a £20 qualifying bet is a bigger headline than the £20 from BoyleSports on a £10 qualifying bet. The structure is comparable: each is a free-bet grant, neither carries a turnover requirement, both have a 7-day expiry. The BoyleSports offer asks a smaller stake to qualify, which is the bettor’s trade if they want the bonus without overcommitting on a single weekend. The Sky Bet offer (three £10 tokens) requires a 5p qualifying bet, which is closer to a deposit-and-bet-anything trigger than to a bet-the-£20 condition; the value of the tokens at minimum odds of 2.0 (1/1) is comparable to Coral’s £40. BetMGM’s offer is paid in four £10 tokens tied to four accumulator bets (two 4+ leg football accas and two sports multiples of 2+ legs), which is a more specific use-case for a customer who places accas.

Reading the offer as a whole. Two £40 free-bet grants from two operators are not the same offer once the qualifying-bet terms and the expiry windows are read. The £20 that has to be staked at minimum 2.0 (1/1) to unlock Coral’s £40 is the qualifier; the £10 at minimum 3.0 (2/1) that has to be staked to unlock SBK’s £60 in free bets (via the Smarkets sportsbook) is a tougher qualifier (3.0 over 2.0) but a larger grant. The breakeven edge of each offer depends on the markets the free bet is used on and the markets the qualifying bet is taken on, not on the headline number.

The turnover this page is asked to verify. Bonus turnover for an offer like Coral’s is zero — the £40 has no multiplier, and the qualifying £20 bet is a single stake, not fifty times it. A bonus turnover table for “£40 free bet, 0x rollover, £20 qualifying stake at 2.0 minimum” is the arithmetic of zero rollover and one wager, which is the whole point of the offer’s structure under the cap. Where a brand still runs a cash bonus (and research has not named one in the GB-licensed set), the cap applies and the rollover is 10x of the bonus value.

Bonuses and free bets after the cap: what the offers now look like

The shape of an enhanced betting offer in 2026 under GB regulation can be read from the offers the Commission-register brands are running. They cluster into four shapes, and a bettor who has read the difference does not need to read each new offer from a standing start.

Free-bet grants, the dominant shape

The £40 free bet for a £20 qualifying bet (Coral, Unibet — Unibet runs the same shape), the £20 free bet for a £10 bet (BoyleSports), the £30 in three £10 tokens for a 5p qualifying bet (Sky Bet), the £40 in four £10 tokens (BetMGM), the £20 free bet of up to £50 plus a £50 free slot funds side (BetTom — note the mixed-product structure is what the cap banned in most constructions; BetTom’s split into sports and casino halves is the surviving version of a category the Commission has been narrowing since 19 January 2026), and the £60 free bet grant for a £10 qualifying bet (Spreadex — spread-betting eligible) are all free-bet grants. None has a rollover on the grant itself. Each has its own qualifying conditions: a minimum stake, a minimum odds line, a deposit method (most GB welcome offers require a debit card or instant bank transfer and exclude credit cards because credit-card gambling has been banned in GB since 14 April 2020), a window in which the qualifying bet has to be placed (Spreadex’s 28 days is the longest in this set), and a window in which the free bets have to be used (7 days from credit is the typical window; QuinnBet’s is 7 days from credit, with minimum odds of 1/2 and maximum odds of 50/1; straight accumulators allowed, Trixies, Patents and Yankees excluded).

Price boosts and acca enhancers

bet365’s daily Bet Boosts and Super Boosts, Bet Victor’s regular price boosts and acca offers, BoyleSports’ Acca Insurance (5+ legs, minimum combined odds of 3/1) and Acca Loyalty (5+ legs), Coral’s Odds Booster on hundreds of markets, William Hill’s Football Acca Boost (2+ legs at minimum odds of 1/5 per leg, cash boost from 3% on a double up to 200% on 20+ legs, maximum boost of £10,000 per online bet, running until 30 May 2027), and Star Sports’ Weekend Enhanced Boosts are all in this category. None requires turnover before withdrawal — the boost is paid as cash or as a small free bet, depending on the offer. BoyleSports’ Acca Insurance pays the refund as a free bet expiring in 7 days, capped at £20; BoyleSports’ Acca Loyalty pays the free bet on a settled qualifying acca, expiring in 7 days. None of these is governed by the 10x cap because none is structured as a cash bonus with rollover.

In-play and live enhancers

DAZN Bet offers Cash Out (availability not guaranteed, bets stand if it isn’t), Bet Builder, daily bet boosts and in-play betting. Unibet offers Uniboosts (daily), live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on UK and Irish horse racing, and Cash Out on thousands of markets. Matchbook runs as a betting exchange — a remote betting intermediary licence, distinct from a remote general betting standard licence — and its new-customer offer of 110 days of commission-free betting is the structural opposite of a free-bet grant (no bonus to clear, lower commission thereafter). Smarkets runs SBK, its consumer-facing sportsbook; SBK’s UK welcome offer is a £20 deposit, a £20 qualifying bet at minimum odds of 3.0, and £60 in free bets credited within 48 hours, alongside Cash Out, Bet Builder and live horse racing streams. The in-play segment is where boosts and enhanced odds land most often, because the in-play margin is what the operator adjusts by adjusting the price.

Spread-betting exceptions

Spreadex is a single firm holding an FCA authorisation for financial spread betting and a Gambling Commission licence for fixed-odds betting. The two businesses share a wallet but not a regulator. The £60 free bet offer is a fixed-odds free-bet grant; the customer who uses it on a spread-betting position enters FCA-regulated territory and may lose more than the deposit. That is the FCA’s framing, not the operator’s: spread-betting losses can exceed deposits. The GB sports betting industry has no other operator running a similar structure, and the customer mix (financial spread plus sports) does not exist elsewhere.

How ten licensed bookmakers stack up

This is the comparison the GB market runs on in 2026. The set below is built from the Commission’s public register: each row carries the account number a customer can enter on the register’s search page to confirm the licence; each block carries the offer that operator states on its own terms page; each block ends on whether the offer pays for the bettor it is aimed at.

The order above is not a ranking. It is the order in which the brands appear on the Commission’s register when sorted by account number, and the order in which they sit in the rest of this page. Each is a real operator; each is GB-licensed; none is “the only” licensed one.

BetMGM

A licensee in the MGM Resorts family running under LeoVegas Gaming PLC, BetMGM UK is the GB extension of a US-facing brand. Its welcome offer is paid in four £10 free bet tokens, two of them tied to football accumulators of 4+ selections and two tied to sports multiples of 2+ selections. That split is unusual: most welcome offers pay the free bets on any market the customer chooses. Here, half of the grant is fenced to accas. For a customer who places long football accas as a habit, that is a perfect structure — the £20 of acca tokens carries the same value as £20 of unrestricted free bets. For a customer who bets singles only, the structure is half-useful: two acca tokens they have to find a use for, two singles-or-multiple tokens that work on any market.

The minimum odds are not stated in the app listing research has seen; the customer reads them on the qualifying-bet terms page before depositing. Free bets valid 7 days. Opt-in required. Live streaming is not part of the offer; safer-gambling tools are listed in the app.

Verdict. The offer pays for the bettor who already builds football accas of four or more legs each weekend. It pays half for the bettor who bets singles, because half of the grant will sit unused. The minimum-odds floor sits below Sky Bet’s 1/1 (1.0) and roughly at Coral’s 2.0 (1/1), but the specifics have to be confirmed on the qualifying-bet terms before any deposit.

bet365

Bet365 does not run a free-bet grant as its headline. Instead it runs two structurally different products: Bet Builder+ (combining markets from a single event into one bet — the same-game-multi concept, usable pre-match and in-play) and Super Boosts (curated price boosts on selected events). Daily Bet Boosts run on top of those. Winnings Boosts on Bet Builders and selected singles are an extra enhancer on already-priced bets. The catalogue is enhancement on top of standard pricing, rather than a welcome-offer grant.

For a customer who already bets singles and accas and is comfortable comparing prices across bookmakers, the bet365 product set is the largest in the GB licensed set by feature count. The licensed-holding entity is Hillside (UK Sports) ENC; the licence is 55148 on the Commission’s register. The bookmaker does not run a free-bet welcome offer that competes with Coral or BoyleSports on grant size; it competes on the depth of the in-play catalogue, the same-game-multi scope and the price-boost volume.

Verdict. The right bookmaker for a customer who already bets singles and accas, has a comparison habit, and wants the largest in-play catalogue in the GB licensed set. A bettor looking for a headline-matching welcome grant will find a deeper in-play experience here instead.

Matchbook

A betting exchange rather than a sportsbook in the conventional sense, Matchbook operates under a remote betting intermediary licence (account 39504), held by Triplebet Limited. The price on Matchbook is set by other customers (back and lay), and the operator earns commission on net winnings rather than margin on each market. The new-customer offer is 110 days of commission-free betting from the date of registration against a deposit; standard commission applies afterwards.

That is a different value proposition from a free-bet grant. A free-bet grant transfers operator balance to customer balance at a defined cost. Commission-free betting transfers the operator’s margin (a different metric) to the customer’s winnings on every successful bet for 110 days. A bettor who would have laid a bet at 3.0 on Matchbook at a 5% commission saves £0.15 per £1 of net winnings for 110 days. The Commission’s 10x bonus cap does not reach commission structures because commission is not a bonus. The 110 days is the entire period the operator has to build a relationship on; after it, the bettor pays full commission.

Verdict. The right bookmaker for a customer who already understands exchange pricing and is laying bets as a habit. This is an exchange platform: because prices are set by other customers rather than the operator, the standard sportsbook price-boost model does not apply.

Unibet

Platinum Gaming Limited, Gibraltar, holding account 45322. Unibet UK runs the same headline offer as Coral: £40 in free bets for a £20+ sports bet at minimum odds of 2.0 (1/1), debit card or instant bank transfer, free bets expire in 7 days. That is an offer price-matched to Coral. The difference is in the catalogue underneath: Unibet offers Uniboosts (daily price boosts), Best Odds Guaranteed on UK and Irish horse racing, Cash Out on thousands of markets, in-play and Unibet TV for live streaming. The bookmaker has run since 1999, per its own statement.

The Unibet offer is identical in headline number to Coral’s because the offer has converged across the GB licensed market to a structure that the 10x cap tolerates: a £40 free-bet grant on a £20 qualifying bet, with no rollover, 7-day expiry, no casino side. The bettor chooses Unibet over Coral when the catalogue underneath (Unibet TV, the Best Odds Guaranteed on horse racing, the Cash Out depth) is more important than which app they prefer.

Verdict. The offer is the same as Coral’s, but Unibet adds the live-streaming layer and Best Odds Guaranteed on horse racing. For the bettor whose routine involves daily racing and football, this operator’s integrated streaming and BOG feature is the primary differentiator.

Betfred

Petfre (Gibraltar) Limited, account 39544. Betfred advertises new-customer free bets and free spins, and the app carries GambleAware support and safer-gambling information. The free-bet component is the part of the welcome offer the customer reads in detail: free spins on casino games from the same operator are an example of the mixed-product structure the 19 January 2026 rules narrowed — a sports welcome with a casino side is now structured as separate offers rather than as one tied bundle, and the customer reads the betting side and the casino side as separate products with separate terms.

Verdict. Betfred’s offer is the closest thing in the GB licensed set to the legacy bookmaker template — high-street heritage, free-bet welcome, free spins on the casino arm. The right bookmaker for a customer who values an established GB high-street brand in their sportsbook. The free spins side has its own terms and the customer reads those separately.

DAZN Bet

DZBT Limited, account 48756. DAZN Bet is the bookmaker run by the DAZN streaming company. The site covers Cash Out (subject to availability — the help page states that bets stand when Cash Out is unavailable), Bet Builder, daily bet boosts and in-play markets. Safer-gambling tools include deposit limits, loss limits and wagering limits.

DAZN Bet does not run the headline free-bet grant the sportsbook-only brands run. It runs an enhanced-price product on top of the standard sportsbook: Cash Out, Bet Builder, daily boosts, in-play. The cash-out framing is the most explicit in the licensed set on this point — the help page names the rule that bets settle as placed when Cash Out is unavailable.

Verdict. The right bookmaker for a customer who bets on events streamed on DAZN and wants the same login. A bettor prioritising a traditional free-bet sign-up bonus should look elsewhere; this offer focuses on in-play enhancements rather than a direct grant.

BetTom

Bet Tom Limited, account 64959. The welcome offer is the split structure: 50% back as a free bet up to £50 on sports, and a matching 50% back as free slot funds up to £50 on casino. That is the post-19 January 2026 version of a sports-and-casino bundle — two halves, each with its own terms, neither with a rollover requirement that would breach the 10x cap. The sports half is a free-bet refund rather than a free-bet grant (the customer bets, gets 50% back as a free bet if the bet loses), which is a refund-on-loss structure that does not run a wagering condition.

The split is unusual: most GB licensed operators have stripped the casino side to keep within the mixed-product prohibition. Bet Tom keeps both sides but breaks them into two distinct offers.

Verdict. The right bookmaker for a customer who plays sports and casino from the same brand and wants both halves of the welcome on separate terms. This platform is not ideal for the dedicated sports-only bettor, as the casino component requires a separate review of terms.

NetBet

Netbet Enterprises Limited, account 39170. Daily Boosts, Profit Boosts, free bet offers, Bet Builder with instant dynamic odds, and sports stats for major leagues. The catalogue is enhancement-led, similar to bet365 and DAZN Bet, with the addition of Profit Boosts (a percentage added to winnings on selected markets) and sports stats pages for major leagues.

The licence has been live; the offer is built around the same enhancer stack several licensed brands run after the bonus cap normalised welcome grants. Daily Boosts are price boosts; Profit Boosts are winnings boosts; Bet Builder is the same-game-multi; sports stats are informational.

Verdict. The right bookmaker for a customer who wants the most enhancer options for the smallest wagering footprint. Welcome grant size is not the headline, so a customer choosing on grant size alone will not pick NetBet.

Smarkets (and SBK)

Smarkets (Malta) Limited, account 39173. Smarkets is a betting exchange (remote betting intermediary licence); SBK is the consumer sportsbook front of the same operator. The exchange side runs commission-based pricing; the SBK sportsbook runs a conventional sportsbook offer. SBK’s UK welcome is a £20 first deposit, a £20 qualifying bet at minimum odds of 3.0, and £60 in free bets credited within 48 hours, alongside Cash Out, Bet Builder and live horse racing streams.

The £60 grant is the largest free-bet grant in the GB licensed set this comparison covers, and the qualifying odds of 3.0 (2/1) are the steepest of any of the free-bet-grant offers — the customer has to place a £20 bet at 2/1 minimum rather than at evens. That trade is the structure: a bigger grant in exchange for a tougher qualifier. The free bets are credited in 48 hours, faster than Coral’s 7-day credit.

Verdict. The right bookmaker for a customer with a £20+ weekend bet who wants the largest free-bet grant in the set and is comfortable with a 2/1 minimum qualifier. Customers seeking a low-odds qualifier will find the 3.0 minimum odds requirement too steep for a standard welcome-clearing strategy.

Star Sports

Star Racing Limited, account 9177. Star Sports runs pre-event and in-play markets, Bet Boosts, Daily Specials, Weekend Enhanced Boosts and in-play on football, horse racing, golf and US sports. The catalogue is enhancer-led, built around the weekly Bet Boost and the Weekend Enhanced Boost product — the pattern most licensed brands run, with the Star Sports twist being US sports in-play.

Verdict. The right bookmaker for a customer who bets on UK and US sport and wants the same bookmaker across both. The wrong bookmaker for a customer whose decision rests on the welcome grant — Star Sports’ offer sits in the enhancer category like NetBet’s and bet365’s, and the comparison on grant size runs against Coral, BoyleSports, Sky Bet, Unibet, Spreadex, Smarkets and BetMGM instead.

An enhanced odds offer in its actual arithmetic

The arithmetic the page was asked to verify. Bonus turnover for Coral’s £40 free bet at zero rollover, qualifying stake of £20 at minimum odds of 2.0 (1/1), expiry of 7 days from credit, is the arithmetic of a free-bet grant: there is no turnover, the qualifying bet is one stake of £20 at minimum odds of 2.0, and the free bets returned £40 of stake credit whose value is the average of stake × (odds − 1) ÷ odds × payout share across the markets the free bet is used on. The qualifying bet has an expected cost on a typical outright market of about 5% of stake (£1 on a £20 stake at a typical margin). The free bets have an average value that depends on the market they are used on and the odds they are taken at, rising with the odds taken (because the (odds − 1) ÷ odds factor rises with the odds).

Under the 10x cap, a £40 cash bonus with a 10x wagering requirement would demand £400 of qualifying bets. Coral has chosen the free-bet-grant structure: no rollover on the grant itself, qualifying-bet stake of £20 (one wager, not twenty), 7-day expiry. That is the structure the cap has pushed the GB licensed set toward, and it is the structure every licensed welcome offer in this comparison runs.

Where the same scenario applies across the set. BoyleSports’ £20 free bet on a £10 qualifying bet is structurally identical: zero rollover on the free bet grant, qualifying bet of one stake at minimum 1/2. The qualifying-bet line is easier (1/2 is below 1/1), the grant is smaller (£20 vs £40). The bettor trades the qualifying threshold and the grant size. The cap does not require free-bet grants to be uniform in size; it forbids rollover on the bonus base exceeding 10x. The free-bet-grant structures are all under that cap by definition (zero rollover is below any positive rollover cap).

What the page is NOT asked to estimate. Bonus turnover assumes only the bonus amount is the turnover base — it does not model the additional rollover some operators run on the deposit + bonus combined base. The cap refers to the bonus base. Where a brand runs a bonus + deposit base, the rollover figure rises. None of the offers in this comparison set, on the public terms research has reviewed, runs that combined base; the terms state a bonus-only or free-bet-grant structure with a separate qualifying-bet stake. The customer reads the terms page before any deposit to confirm which base the operator uses.

Offshore and unlicensed: what licensed play gives up to stay licensed

The licensed path has costs an unlicensed site does not. Verification before the first deposit. Identity documents uploaded and checked. Source-of-funds questions when deposits net of withdrawals exceed £150 in a rolling 30 days (from 28 February 2025). A GAMSTOP self-exclusion that propagates to every licensed GB site. No anonymous play. The bonus cap’s ceiling on turnover. The £150 net-spend threshold that triggers a public-record check. The Advertising Standards Authority rules on who may appear in a marketing image. These are the licence conditions the operator pays for by paying the licence, and the costs of those conditions are passed to the customer as friction.

The unlicensed path removes all of those. No verification. No GAMSTOP, because the operator is not a GAMSTOP member. No Commission complaints route, no approved alternative-dispute-resolution body, no British consumer redress if funds are withheld. No £150 vulnerability check. The 10x cap does not apply, because the cap is a GB licence condition and the operator is not GB-licensed. Marketing claims on offer sizes are not policed by the ASA or the Commission, because the marketing is not under GB jurisdiction. Whether the operator even has the funds to pay out on a winning bet is not testable from a GB register, because the operator is not on the register.

The licensed-versus-unlicensed comparison is not “safe vs unsafe” — that frame understates what the licence does. It is “frictions the customer bears in exchange for protections the customer recovers if anything goes wrong”. The verification is the friction; the IBAS dispute route is the protection. The £150 check is the friction; the Commission investigation on a complaint is the protection. The bonus cap is the friction (a smaller welcome than an unlicensed operator might run); the customer reads the bonus terms knowing the 10x ceiling exists, which is the protection. The bettor weighs the trade once, when picking a bookmaker, then rarely revisits it.

A bettor on an unlicensed site who has a dispute does not have a GB regulator to complain to. The Commission’s powers of enforcement — cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers — aim at the operator, not the customer. The Commission’s court-order DNS blocking powers are present or pending; the ISP-level blocking of unlicensed sites is not in continuous operation in the way that phrasing might suggest, and the bettor reads the offshore offer without that operational certainty. The practical line is: if a winning bet is not paid, the GB-licensed customer has an IBAS route and a Commission route, and the unlicensed customer has the operator’s word and the operator’s payment processors.

Choosing on the offer

The bettor picks on what the offer actually does, not on the headline number. Three questions to ask before claiming any welcome offer, taken from the GB licensed set:

What is the qualifying-bet minimum, on what odds, and on what expiry? Coral and Unibet: £20 at minimum 2.0, 7 days to qualify. BoyleSports: £10 at minimum 1/2. Sky Bet: 5p at minimum 1/1. Smarkets (SBK): £20 at minimum 3.0. Spreadex: £10 fixed-odds bet, 28-day window to place the qualifying bet.

How is the grant paid, and what is the expiry on the grant? Coral: £40 in free bets, 7 days from credit. Unibet: £40 in free bets, 7 days from credit. BoyleSports: £20 in free bets (€30 in free bets for Irish players). Sky Bet: three £10 free bet tokens, 7 days. BetMGM: four £10 free bet tokens (two acca, two multi), 7 days. Betfred: free bets and free spins, terms stated in app. BetTom: free bet up to £50 plus free slot funds up to £50. Spreadex: £60 in free bets. Smarkets (SBK): £60 in free bets, 48 hours from qualifying.

What are the markets the free bet can be used on, and at what minimum odds? Most free bets in this set have no market restriction; QuinnBet’s free bets are restricted to odds of 1/2 (1.5) to 50/1, with straight accumulators allowed and Trixies, Patents and Yankees excluded. Customers who play combination bets read this list first.

A bettor who answers these three questions on each offer before claiming it has read the offer the way the offer was written. The headline number is the third or fourth thing on the page; the qualifying threshold, the expiry window, the markets and the minimum odds are the first three.

Fundamentals: what an enhanced odds offer is, and isn’t

“Enhanced odds” is a phrase bookmakers use on banner ads and home pages. It is not a regulatory term, and the Commission does not recognise it. It refers, in bookmaker usage, to a price on a market that is higher than the same operator’s headline price would otherwise be, for a defined window. The “enhancement” is operator-funded (the operator sets a price at a small loss to attract a customer to the market, expecting to make the loss back on volume). It is structurally separate from a free bet, which is a bet credit granted on a qualifying action.

A “price boost” is the same mechanism under a different name. bet365’s Super Boosts and daily Bet Boosts; BoyleSports’ Daily Specials and Weekend Boosts; Coral’s Odds Booster; NetBet’s Daily Boosts and Profit Boosts; Smarkets’ Supercharge-style enhancements through SBK; Star Sports’ Weekend Enhanced Boosts; Kwiff’s Supercharge that can lift a price from 2/1 to 20/1 — each is a price enhancement on a specific market, paid as a larger payout on a winning bet rather than as a free bet. The boost does not usually carry a wagering condition (the boost pays out at settlement, not as a free bet credit requiring turnover), and the 10x cap does not reach it because there is no bonus base.

An “enhanced bet offer” is a marketing term covering three types of incentive: free bets, price boosts, and same-game-multi or bet-builder products. Each is sold as “enhanced” because it pays the customer more than a standard market would, but each is structured differently under the licence. The 10x bonus cap limits the free-bet structures, but price boosts and bet-builders sit outside that cap. The enhancement on a price is paid as a larger payout at settlement, rather than as a bonus that requires rollover.

Verification, payments and the customer’s first session

A licensed GB bookmaker opens the customer’s account with a verification step. Passport, driving licence, identity document — the operator verifies name, address and date of birth before the first deposit. The check is repeated at withdrawal because address and source-of-funds rules attach at withdrawal. The customer does not see the operator’s Commission licence number on the first page (operators do not usually publish that), and the customer does not need to: the public register is searchable by business name, trading name, domain or account number, and the customer enters any of those.

Payment methods at a licensed operator. Credit cards are banned for gambling in Great Britain since 14 April 2020 (LCCP condition 6.1.2), including credit-card-funded e-wallet top-ups. Debit cards and bank-based payments are not covered by the ban. Coral’s published payment-methods list includes Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly — none of which is a credit card. Most licensed operators require a debit card or instant bank transfer for the welcome offer’s qualifying deposit; the welcome-offer terms on each operator’s site state the eligible payment methods.

Withdrawals are paid back to the payment method that funded the deposit, with operator turnover rules on the sequence (the operator may require the deposit method to be turned over before a withdrawal can be made to a different method). The customer reads the operator’s withdrawal policy before any deposit, because the rule differs by operator and by method.

Source-of-funds questions are routine at higher spend. The £150 rolling 30-day net-spend threshold is the public-record check; above that, an operator may ask for payslips, bank statements or other evidence of source of funds. The Commission treats the check as licence-condition rather than as over-reach, and customers expect the question at higher spend rather than seeing it as unusual.

The first session’s sequence. Sign-up with name, address, date of birth. Verification upload (passport or driving licence). Deposit from an eligible method. Qualifying bet at minimum specified odds on a market of the operator’s choice. Free-bet credit at the operator’s stated interval (7 days for Coral; 48 hours for Smarkets). Free-bet use on a market the customer chooses, within the free-bet’s expiry window. Withdrawal of any winnings to the original payment method, subject to identity verification on withdrawal.

A customer who has used an unlicensed site before will find this sequence full of friction. The friction is the licence’s point. The bettor who has read the corresponding friction on the unlicensed side (no verification, no dispute route, no Commission complaint, no source-of-funds check) reads the licensed sequence as the cost of protections that the unlicensed side does not carry.

The bettor’s own checklist

Before depositing at any of the ten brands above:

Confirm the licence on the Commission’s public register. The licensee’s name, the trading name, the domain and the account number all appear; the bettor cross-checks any of them. An operator cannot claim a GB licence the register does not show.

Read the welcome-offer qualifying terms. Minimum deposit, qualifying stake, minimum odds, eligible payment methods, qualifying window, expiry on the free bets. Any mismatch between the terms and the headline voids the qualifying-bet stake.

Read the safer-gambling tools. Deposit limit, loss limit, wagering limit. The customer sets a deposit limit at sign-up — the operator offers this — and the limit applies across the customer’s account lifetime, surviving a marketing push, a bonus chase or a bad run.

Set GAMSTOP if the customer intends to self-exclude. Six months, one year, five years, five years with auto-renewal. The exclusion applies across every GB-licensed online operator, not just the one the customer signed up at.

Use the safer-gambling contact routes if the customer has slipped past their own deposit limit. GamCare runs the National Gambling Helpline. GambleAware funds treatment. NHS clinics run in several regions. Gamblers Anonymous runs peer-support meetings. None of these is a regulator; all of them are the routes a bettor takes when limits have stopped working.

What the checklist is not. It is not a list of approval signals for the brand. It is a list of decisions the bettor makes on their own account, before any deposit, and the decisions the bettor revisits only when the bettor’s own circumstances change. The brand does not gain anything from the bettor following the checklist; the bettor does.

Where the data stops

Three areas this page does not extend into.

The 10x bonus cap’s edge cases. Whether the cap applies to free bets with no wagering condition has not been established in published guidance. The Commission’s 19 January 2026 rules address the bonus base and the mixed-product prohibition; they do not plainly name a free-bet grant as either inside or outside the cap. Each operator’s free-bet terms are stated, and the cap is observed by structure, but the plain answer to “is this free bet governed by the cap” is not on the Commission’s site at the time of this comparison.

The 30 September 2026+ second phase of mandatory deposit-limit changes. Whether the second phase is live, deferred, or further amended has not been pinned down. The first phase has applied since 31 October 2025. The 30 September 2026+ date is a scheduled change, not a confirmed live change. A bettor reading this in 2026 treats the second phase as announced, not active.

The financial risk assessment start date. The Commission announced a staged plan on 7 July 2026 to extend the financial vulnerability check into formal affordability checks; no start date has been set. The public-record vulnerability check from 30 August 2024, on the £150 rolling 30-day net-spend threshold, is the current state. The bettor reads the affordability-check framing as future change.

Those three points are not established. The page writes them as research states them: named as not established, scheduled as scheduled, announced as announced. A bettor who needs the current state checks the Commission’s consultations and guidance pages, which are updated as the rules are updated.

Closing judgement

The GB licensed sportsbook market in 2026 has settled into a shape the 19 January 2026 bonus rules pushed it into: free-bet grants sized between £20 and £60, qualifying bets of £10 to £20 at minimum odds between 1/2 and 3/0, 7-day expiry windows, debit-card funding, no casino side. Enhancer products — price boosts, acca insurance, acca loyalty, same-game-multi — sit alongside the free-bet grants because the cap does not reach them, and they carry the catalogue value the bettor buys in the first place.

The customer who wants the biggest free-bet grant picks Smarkets (SBK), accepting the 3.0 minimum odds qualifier. The customer who wants the easiest qualifier picks Sky Bet (5p at 1/1 minimum). The customer who wants the exchange model picks Matchbook, accepting the absence of a free-bet grant. The customer who wants the largest in-play catalogue picks bet365. The customer who wants the live-streaming layer and Best Odds Guaranteed on horse racing picks Unibet. The customer who wants the high-street heritage picks Betfred. The customer who values an established US-facing brand picks BetMGM, accepting that the offer is split between acca and multi tokens. The customer who wants both a sports welcome and a casino welcome with separate terms picks BetTom. The customer who wants a US-sports tilt picks Star Sports. The customer who values the refund-on-loss structure picks DAZN Bet, NetBet or Betfred, depending on which enhancer stack the customer prefers.

The licence is the floor under every one of them. The Commission does not rank operators and does not pick winners. The Commission’s register is the test a bookmaker must pass to advertise the offers above; the page is for the bettor who has read the offer terms and is comparing what the offers actually do, which is the comparison no welcome-offer banner has ever made on its own.

Frequently asked questions

What does enhanced win mean in golf betting?

Enhanced win in golf is a price boost on the outright winner market — the bookmaker raises the price on a selected player above its standard line for a defined window. Payouts are calculated on the boosted price; the stake is paid as normal on a winning bet. The boost does not change the bet’s structure: it is still a single on the tournament winner, paid at the enhanced price if the player wins.

What is enhanced win only betting?

Enhanced win only betting is a price-boost variant that applies to the win portion of an each-way bet rather than to the place portion. The each-way bet still pays two ways (win at the enhanced price, place at the operator’s place terms); the enhancement targets only the win leg. Each-way bets double the stake: a £10 each-way is a £20 total stake, and the customer reads the each-way terms at the racecourse-level rule the operator publishes.

What is an enhanced bet?

An enhanced bet is a marketing term bookmakers use on banner ads, home pages and price-boost pages. It covers any of three things: a free-bet grant issued on a qualifying bet, a price boost (a higher price on a selected market for a defined window), or a same-game-multi / bet-builder product with an enhanced payout. The term is not a regulatory category, and the Commission’s rules address each structure separately. A “100% bonus” pitch is a free-bet grant; a “best odds” pitch is a price boost; a “bet builder+” pitch is a same-game-multi.

What is the maximum wagering requirement on a betting bonus in Great Britain?

10x the bonus value, with effect from 19 January 2026. Mixed-product promotions (an offer requiring gambling on two or more product types such as betting and casino) are banned. Whether the cap applies to free bets with no wagering condition is not established. The cap covers the bonus base; it does not cover price boosts, acca insurance or same-game-multi payouts, which sit outside the bonus structure.

What do minimum odds and the wagering requirement mean in a sign-up offer?

The minimum odds are the floor below which a qualifying bet does not count toward the wagering requirement. The wagering requirement is the multiple of the bonus base that must be turned over in qualifying bets before the bonus can be withdrawn. A £10 bonus with 10x wagering needs £100 of qualifying bets at the minimum odds line; Coral’s qualifying line on the £40 free bet offer is 2.0 (1/1), and the customer reads the minimum odds stated in the qualifying-bet terms before placing the stake.

Why is the stake of a free bet not paid back with the winnings?

Free bets are bet credits, not cash stakes. The operator credits the bet credit, the customer uses it on a market, and on a winning bet the operator pays the winnings only — the stake (the bet credit itself) is not returned because it was never the customer’s cash. That is the structural difference between a free bet and a cash stake; the customer’s expected value of a free bet is stake × (odds − 1) ÷ odds × payout share, which is the average return across outcomes rather than the maximum return.
