A matched bettor does not predict outcomes. They exploit the difference between what a bookmaker gives away in a promotion and what an exchange will charge to remove the risk. Done badly, it leaks money through commission, minimum-odds rules and exchange margins. Done carefully, it produces a small, repeatable profit on terms the bookmaker itself sets. This page walks through the mechanism in plain arithmetic, the British rule book that sits on top of it, and the operators a UK bettor needs in front of them to run it.

Current as of 27 October 2026, checked against the Gambling Commission’s public register.

The Statute: What the Gambling Commission Actually Allows

The framework is the Gambling Act 2005, which covers Great Britain — England, Scotland and Wales — and the Gambling (Licensing and Advertising) Act 2014, which extended it to any operator whose remote facilities are used here, regardless of where the operator is based. A Curaçao or Malta licence does not stand in for one. The Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport, is the regulator, and its public register is the only test of whether a brand holds a licence. Several gambling companies run more than one brand under the same licence (Paddy Power and Betfair, for example, sit with PPB Counterparty Services Limited), so a brand being licensed is a fact about its parent.

Betting exchanges are licensed separately as “betting intermediaries”, and their rules — commission on net winnings, no commission on net losses, the practical range of odds — are theirs to set. The register lists them on the same search page as fixed-odds bookmakers, and a matchbook or smarkets entry shows the intermediary status in its categories column.

Financial spread betting sits outside the Commission’s remit. Spreadex, for instance, holds a Financial Conduct Authority authorisation for spread betting and a Gambling Commission licence for its fixed-odds product. Spread betting losses can exceed deposits. That is a different product with a different regulator and a different arithmetic.

Bonuses and Free Bets Under the New Rules

Since 19 January 2026 the Commission has run a cap on bonuses that no operator licensed for Great Britain can step over. Wagering requirements are limited to 10x the bonus value: a £10 bonus at the old 50x turnover would have demanded £500 of qualifying bets; under the cap no more than £100 of qualifying bets is allowed. Free bets without a wagering condition are the closest thing to clean value, because what the bettor has to do to extract them is set by the offer’s expiry, the markets it can be used on, and the rule that the stake is not returned.

The same rule change banned mixed-product promotions. A welcome package that hands out a sports free bet alongside free casino spins as one bundle is no longer legal in Great Britain. Operators can still run a sports-only offer and a separate casino-only offer, but the cross-sell that used to be the standard welcome shape is over.

Identity, Age and Source of Funds

Every GB-licensed online operator checks the customer’s name, address and date of birth before the first deposit or bet — including with a free bet or promotional credit — under customer due diligence rules in force since 7 May 2019. Anonymous play is gone. At higher spend a financial vulnerability check runs (LCCP condition 3.4.4, in force since 30 August 2024) when deposits minus withdrawals exceed £150 in a rolling 30-day window (the threshold took effect on 28 February 2025). It is a public-record check — bankruptcy, county court judgments — not a credit reference or income check.

Financial risk assessments, the “affordability checks” of the press, have been announced in a staged plan (a Commission article of 7 July 2026) without a start date. They are not yet in force.

Marketing Rules That Shape What You See

Advertising sits with the Advertising Standards Authority through the CAP Code (non-broadcast) and the BCAP Code (broadcast), and with the Commission’s own marketing conditions in the LCCP. CAP Code section 16 requires gambling advertising to be socially responsible, not of strong appeal to under-18s, and prevents anyone who looks under 25 from featuring in an ad (with an exception for ads placed at the point of betting). Since 1 August 2019 betting advertisements have not been shown on UK television from five minutes before a live sporting event to five minutes after it, before the 9 pm watershed — horse and greyhound racing excluded. From the 2026/27 Premier League season gambling sponsorship disappears from the front of matchday shirts; sleeves and perimeter boards are unaffected. Both moves are voluntary industry codes, not statute.

What the Customer Pays in Tax

The bettor pays no tax on betting winnings in Great Britain. That is general information, not advice, and a professional gambler owes HMRC a different conversation. General Betting Duty is the operator’s tax on gross profits and currently sits at 15%; from 1 April 2027 a new remote betting rate of 25% will apply within that duty, with remote bets on UK horse racing, betting-shop terminal bets, pool betting and in-person betting staying at 15% (HM Government policy paper of 26 November 2025). Until that date the remote rate is 15%. How far operators pass duty on through their prices is not established.

Safer Gambling: What the System Catches You Doing

GAMSTOP is the national multi-operator online self-exclusion scheme. Every GB-licensed online operator has been a mandatory participant since 31 March 2020, which means a customer who has registered with GAMSTOP cannot open new accounts at any participating site or app. Exclusion periods are six months, one year, five years, or five years with auto-renewal. After the minimum period runs out, the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. The scheme covers online channels; betting shops use a separate system.

A deposit limit is mandatory under the Commission’s Remote Technical Standards (RTS 12). The first changes have applied since 31 October 2025; a second phase was postponed to 30 September 2026, and whether it is live now is not established. There is no state-set ceiling on deposits or losses — the limit is the customer’s own choice within the technical standard.

Credit cards have been banned for gambling in Great Britain since 14 April 2020. A credit-card-funded payment through an e-wallet is caught by the same rule. Debit cards and bank-based payments are unaffected.

Help lines and services exist outside the operator. GamCare runs the National Gambling Helpline. GambleAware funds treatment. NHS gambling clinics operate in several regions. Gamblers Anonymous runs peer support. None of them is a regulator; none of them replaces the complaint routes a licensed operator owes you.

Why Limits and Restrictions Catch Up with Matched Bettors

Bookmakers are under no duty to keep a customer open, and matched betting produces a recognisable pattern: small qualifying losses, repeated free-bet extraction, low margins on the side. Operators may restrict a customer’s account, set maximum stakes the customer cannot raise, or close the account entirely. The Commission’s rules protect a customer from unfair treatment, but the right to close a profitable account sits with the operator. The technique is legal; staying welcome at every shop is a different problem.

The Incentive: How a Free Bet Is Actually Valued

A free bet is a credit the operator hands over on terms. The headline figure — “£30 in free bets” — is not the value. Three things decide what it is worth: whether the stake is returned with winnings, the minimum odds the free bet must be placed at, and the time the bettor has to use it before it expires.

When the stake is not returned — the standard for a British free bet — the free bet’s value is its face amount multiplied by the implied edge at the odds used, adjusted for the margin the market carries. A free bet worth £30 placed at decimal odds of 1.90 (9/10 fractional) on a two-way market priced symmetrically at 1.90/1.90 — an example, not a quoted price — has a payout share of roughly 52.6% and a margin of 47.4% on the round. The £30 free bet is worth something in the region of £30 × (1.90 − 1) ÷ 1.90 × 0.526, which is approximately £7.46 on average. That is the offer’s expected value, not a payout, not a guaranteed return; it is the average of many outcomes over many bets.

Push the odds higher and the headline value rises; push them past the maximum the bookmaker will accept and the free bet is voided. Most operators set minimum odds in the 1.50 to 2.00 range (1/2 to evens) — Sky Bet’s free bets require single or each-way markets, exclude multiples and exclude virtuals, and expire 30 days after crediting. Betway’s free bets carry 1x wagering at minimum odds of 1.75 or higher. Dabble’s welcome free bets expire after 7 days with the stake not returned. The figures on offer lengthen the longer the bettor has to find a market; the figures on minimum odds decide how big the edge has to be.

The Qualifying Bet: The Smaller the Loss, the Cleaner the Run

A qualifying bet is a real-money bet that unlocks the free bet. The matched bettor places a back bet at the bookmaker and a lay bet at an exchange on the same outcome at odds close enough that the return either way is roughly equal. The back bet wins at the bookmaker and the lay bet loses at the exchange; or the back bet loses and the lay bet wins. Either way, the bettor comes out close to even, minus the exchange’s commission and minus the difference in odds between the two sides.

The qualifying bet is the part of the technique that costs the bettor money. The free bet is the part that makes it back. A bookmaker that hands out a £30 free bet on a £10 qualifying bet is asking the bettor to absorb a small, expected loss on the £10 in exchange for the £30 free bet’s expected value. Whether the trade is worth doing is a question of how small the qualifying loss is and how favourable the free bet’s terms are.

Why Account Multiplication Matters

A single bookmaker’s welcome offer is not a matched-betting business; it is the entry fee. The technique runs across many operators, each with its own sign-up terms and its own shape of free bet, with the bettor moving funds between accounts as the offers run out. Some operators cap welcome offers at one per household; some use postcode and payment-method checks to enforce it. The arithmetic improves as the bettor spreads their action and manages the qualifying loss across a larger set of bets.

Operators notice. The pattern of low-margin, free-bet-driven play is detectable from the account’s history, and operators may restrict or close such accounts. The Commission does not require an operator to keep a customer open. The matched bettor’s edge exists in the gap between the offer and the price the bettor pays to remove the risk; that gap closes as soon as the bookmaker decides the customer is unprofitable.

The Comparator: Ten UK-Remote-Licensed Operators a Matched Bettor Uses

Every operator below holds a Gambling Commission remote licence listed on the Commission’s public register at the access date above. None of them is the only licensed brand; the register lists many more. Where research carries no figure for a column, the cell is left blank rather than filled in with a guess.

The brand sits inside a structure of choices. Betfair and Matchbook and Smarkets run exchanges or have exchange arms; matched betting without an exchange is impossible, because the lay bet that covers the back bet has nowhere else to live. The others are sportsbooks whose welcome offers are the input the matched bettor works with.

Betfair

The Betfair exchange is the largest in Britain and the default destination for the lay side of a matched bet. Its Sportsbook shares the licence holder with Paddy Power — PPB Counterparty Services Limited sits behind both — so an offer restricted to one is restricted at the holding level. The Sportsbook carries Bet Builder, in-play betting, free live streaming of UK and Irish racing and football within the app, and a 90 Minute Payout market that settles on the result at the 90-minute mark regardless of extra time. Matched bettors split their action between the exchange for the lay bet and the Sportsbook for the back bet when a Sportsbook-specific promotion is in play.

Smarkets

Smarkets runs as a betting intermediary under Smarkets (Malta) Limited and sits beside the SBK sportsbook under the same group. The exchange charges commission on net winnings per market and nothing on net losses. SBK’s welcome offer — £20 first deposit and a £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours — is a three-times multiplier on the qualifying stake, which makes it a candidate for matched betting but with a minimum-odds floor that pushes the bettor toward higher-margin selections. Cash Out, Bet Builder and live horse racing streams sit on SBK.

Matchbook

Matchbook runs both general betting and intermediary categories under Triplebet Limited. The new-customer offer is 110 days of commission-free betting from registration, contingent on registering through the listing channel and making a deposit; standard commission kicks in afterwards. Commission-free windows lengthen the matched bettor’s qualifying phase and shift more of the edge toward the lay side of the bet. After the 110 days, the edge has to clear the exchange’s standard rate.

VBet

VBet runs under SCGO Limited on a general betting standard licence. The welcome is a £10 free bet if the first-ever bet of £10 or more loses — a single-stake safety net rather than a free-bet bundle. The shape suits a bettor who would have placed the first bet anyway; the £10 free bet is the upside of losing it. The minimum-odds rule attached to the qualifying bet sits in the operator’s full terms.

Coral

Coral runs under LC International Limited, the same holder as Ladbrokes, on a general betting and intermediary licence. The “Get £40 in Free Bets when you bet £20” offer asks for a £20 deposit and a £20 sports bet at minimum odds of 2.0 (1/1), with £40 in free bets issued within 7 days and expiring 7 days after issue. A 7-day expiry on the free bet is short and constrains the matched bettor to a small set of markets where the lay price clears the qualifying odds.

Fitzwilliam Sports

Fitzwilliam Sports describes itself as a Dublin bookmaker with capped membership. The licence sits with SBKI Limited, and the welcome — a “High Stakes Welcome” subject to compliance criteria — targets a different reader from the standard welcome bundle. Matched bettors rarely treat capped-membership books as a routine source of free bets.

Geoff Banks

The Geoff Banks app is published by GB Sports Advisors Limited. It offers live in-play prices and ante-post prices on future events — a more specialised bookmaker, narrower in market coverage than the high-street brands. The welcome shape sits outside the matched-betting standard run; the operator’s value to a matched bettor depends on whether its in-play or ante-post prices produce free-bet offers the bettor can extract.

BetUK

BetUK runs under LeoVegas Gaming PLC on a general betting standard licence. The sports welcome offers four £10 free bets — two football accumulators of 4+ selections and two multiples of 2+ — to a customer who deposits £10 or more and places a sports bet within 7 days, with a 7-day validity and opt-in required. Accumulator-shaped free bets are harder to lay off cleanly than singles, and the qualifying structure adds a constraint the matched bettor has to plan around.

LiveScore Bet

LiveScore Bet runs under LiveScore Betting and Gaming (Gibraltar) Limited. Its payment set — Visa and Mastercard debit, Apple Pay, PayPal, Pay by Bank and Revolut Pay — is the broadest in the comparator and matters when a matched bettor wants to fund a new account without using a previously charged card (operators often enforce one welcome per payment method). The welcome shape sits on the operator’s full terms.

BetTom

BetTom runs under Bet Tom Limited. The sports welcome is 50% back as a free bet of up to £50, paired with a matching 50% back up to £50 as free slot funds for casino play — a structure that, under the 19 January 2026 mixed-product ban, is no longer the shape a new welcome offer could take, and would need to be split into separate sports and casino offers going forward. The free-bet side, considered alone, is the relevant matched-betting input.

The Fundamentals: What the Matched Betting Machine Looks Like

Matched betting is a technique for extracting value from bookmakers’ promotional credit, using at least two accounts — a bookmaker that offers a free bet and a betting exchange on which to lay off the opposing outcome. The back bet sits with the bookmaker; the lay bet sits with the exchange. The bookmaker pays the back bet if it wins; the exchange pays the lay bet if the selection loses. The two bets cover each other and the bettor comes out roughly even after commission, with a small profit margin locked in by the free bet’s value.

The matched bettor is not gambling on the outcome. They are pricing the gap between the bookmaker’s offer and the exchange’s price. Where that gap is positive — where the free bet’s value, after the stake-not-returned adjustment, exceeds the cost of laying off the bet — the bettor places the bet. Where the gap is negative, they do not.

Three forces compress that gap. First, exchange commission on net winnings reduces the lay price. Second, the difference in odds between the bookmaker’s back price and the exchange’s lay price creates a qualifying loss the bettor has to absorb. Third, the bookmaker’s minimum-odds rule for the qualifying bet and the free bet shrinks the set of markets where the technique works. A bookmaker that hands out a £30 free bet with no minimum-odds constraint is offering a wider set of extraction paths than one that ties the free bet to a 5.00 minimum.

The Mechanics in Two Sentences

Back bet at the bookmaker on a result. Lay bet at the exchange against the same result at close to the same odds. The two bets settle against each other, and the free bet’s value lands in the bettor’s account as the spread between them.

Why Exchanges Exist and Why They Matter

A betting exchange matches customers against each other rather than against the house. One customer backs a selection; another lays it. The exchange takes a commission on net winnings per market and nothing on net losses. Exchanges restrict odds to a practical range — generally between 1.01 (1/100) and 1000 (999/1) — to keep the books clean and the matching realistic. Without the exchange, the matched bettor has no place to lay off the back bet, and the back bet is just a bet.

The matched bettor’s edge lives in the difference between the bookmaker’s free bet and the exchange’s price for removing the risk. That edge is small per bet and large in aggregate. It also depends on liquidity — an exchange with thin liquidity in a market produces a wider gap between back and lay, which costs the matched bettor more in qualifying loss. The major exchanges (Betfair, Smarkets, Matchbook) carry the depth a matched bettor needs for football, horse racing and the major US sports; thinner markets force a wider lay price and a less favourable trade.

The Two Kinds of Bet in a Pair

The qualifying bet is a real-money bet that unlocks the free bet. It costs the bettor a small, expected loss. The free bet is the promotional credit the bettor extracts. The expected value of the free bet minus the expected loss of the qualifying bet is the net profit on the trade, before the time and the account-restriction risk are counted.

The free bet’s value sits in three places: whether the stake is returned, the minimum odds, and the expiry. When the stake is returned, the free bet behaves like a discount on a winning bet; when it is not, the free bet is a credit at the odds used, less the exchange’s commission on the lay bet. Most British free bets do not return the stake. A free bet worth £30 at decimal 1.90 (9/10) on a symmetric market has a payout share of about 52.6% on the round, and a free-bet value in the region of £30 × (1.90 − 1) ÷ 1.90 × 0.526, which is approximately £7.46 on average across many bets. That is the offer’s expected value as an average, not a payout.

Account Restrictions: The Ceiling on the Technique

Bookmakers may restrict or close accounts they judge unprofitable. The Commission’s rules protect customers from unfair treatment but do not require an operator to keep a customer open. The matched bettor’s pattern — small qualifying losses, repeated free-bet extraction, low margins — is recognisable from account history. Some operators respond with maximum-stake limits that block the next qualifying bet. Some close the account outright. The matched bettor spreads action across many operators and accepts that each account has a finite life. The business is not a permanent state; it is a sequence of welcome offers and reload promotions across a rotating set of books.

What Changes When the Operator Pushes Back

A bookmaker that limits a customer’s maximum stake to a level below the qualifying bet’s required size ends the matched bettor’s use of that book for that offer. A bookmaker that closes an account ends the bettor’s relationship with the brand. The Commission’s rules require the operator to treat the customer fairly in doing so — a return of remaining funds, an explanation, a complaints route to an alternative dispute resolution body — but the right to restrict is the operator’s.

The matched bettor’s defence is to spread action, to place bets in a shape that does not trigger the operator’s anti-promotion heuristics, and to read the operator’s terms before each offer. The arithmetic is stable. The accounts are not.

The Calculation: What a £30 Free Bet Is Worth

A free bet whose stake is not returned has a value of its face amount times the implied edge at the odds used, adjusted for the market’s margin. The arithmetic is the matched bettor’s input to deciding which offers to take.

Take a £30 free bet on a two-way market priced symmetrically at decimal odds of 1.90 (9/10 fractional) on each side. The payout share — 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90) — is approximately 0.5263, or 52.63%. The market’s margin is 1 minus that, or about 47.37%. The free bet’s value, with the stake not returned, is £30 × (1.90 − 1) ÷ 1.90 × 0.5263, which is approximately £7.46 on average.

That is the offer’s expected value as an average over many bets. No single bet pays £7.46. A winning bet pays £30 × (1.90 − 1) = £27; a losing bet pays nothing. The £7.46 is the average, weighted by the chance of winning (about 52.6% at symmetric odds before the exchange’s take).

Push the odds higher and the free bet’s expected value rises. At decimal 3.00 (2/1) on the same symmetric two-way market the payout share is 1 ÷ (1 ÷ 3.00 + 1 ÷ 3.00) = 0.50, the margin is 0.50, and the value is £30 × (3.00 − 1) ÷ 3.00 × 0.50, which is exactly £10 on average. The bookmaker’s minimum-odds rule, typically in the 1.50 to 2.00 range, sets the floor under the offer’s expected value.

The headline price is not the offer. The offer is the free bet’s expected value at the odds the operator allows, net of the qualifying loss the bettor has to absorb to unlock it. A £30 free bet at minimum odds of 1.50 (1/2) on a symmetric market is worth £30 × (1.50 − 1) ÷ 1.50 × 0.5714, which is approximately £5.71 on average. The same face value at minimum odds of 2.00 (evens) is worth £30 × (2.00 − 1) ÷ 2.00 × 0.50 = £7.50 on average. The expiry on the free bet — 7 days at one end of the comparator, 30 days at another — and the markets it can be used on — singles and each-way at one operator, accumulator-shaped at another — are the constraints that turn the headline number into an actual extraction.

The qualifier’s expected loss is the matched bettor’s cost. A £10 qualifying bet at decimal odds of 2.00 (evens) at the bookmaker and 2.02 at the exchange, balanced to cover both outcomes, costs the bettor the exchange’s commission on the winning lay plus the gap between the two prices. On a typical football match the qualifying loss runs from a few pence to a couple of pounds; on a thin market it runs higher. The bettor’s profit on the offer is the free bet’s expected value minus the qualifying loss. Welcome offers vary widely; the right framing is “expected value at the stated terms”, not “headline price”.

The Comparator Set in Context

The ten operators above are the ones research carries for this page; many more hold a GB remote licence on the Commission’s register. Betfair, Smarkets and Matchbook are the exchanges a matched bettor lays off on; the rest are the bookmakers the matched bettor takes free bets from. The split between the two shapes — intermediary on one side, general betting on the other — is the practical division of the set.

Matched bettors do not need every brand on this list; they need an exchange and a steady stream of bookmaker offers. Some operators welcome matched bettors; others restrict them aggressively. Coral and Betfair run under shared holdings (LC International Limited, PPB Counterparty Services Limited), and a restriction at one brand sits inside the relationship with both. BetUK under LeoVegas Gaming PLC carries the same concentration risk. The matched bettor reads the operator’s terms before each offer and accepts that each account is finite.

The Commission’s 10x bonus cap, in force since 19 January 2026, is the regulatory floor. Any offer that asks for more than 10x wagering on a bonus is not legal in Great Britain; the matched bettor can take that as given. The £150 financial vulnerability threshold, the GAMSTOP coverage, the credit-card ban and the no-mixed-product rule are the other rules that shape the welcome offer set. None of them makes matched betting illegal; all of them change the shape of the offers a matched bettor can extract from.

What a Matched Bettor Does First

Open an exchange account at Betfair, Smarkets or Matchbook. Fund it. Then open a bookmaker account at one of the licensed sportsbooks, claim the welcome offer, place the qualifying bet, lay it off at the exchange, and extract the free bet’s expected value on the same terms. Move to the next bookmaker. Spread action across several brands to manage the risk of an account restriction.

The matched bettor is not a tipster and not a forecasting model. They are an extractor of promotional value under terms the operator has chosen to publish. Where the operator’s terms change, the extraction path changes. The Commission’s rules are the floor under those terms.

A Note on Offshore Sites

A betting site licensed outside Great Britain is not licensed for Great Britain. The 2014 Act closed that loophole. A Curaçao or Malta licence does not authorise a brand to take bets from customers in Great Britain; a brand doing so without a GB licence commits an offence under section 33 of the Gambling Act 2005, aimed at the operator. No offence aimed at the customer was found in the statute; the customer’s loss is the loss of protection — no GAMSTOP coverage, no Commission complaints route, no approved alternative dispute resolution body, no British consumer redress if funds are withheld, no 10x bonus cap, no £150 vulnerability check.

Enforcement against unlicensed sites runs through cease-and-desist notices, search-engine referrals and work with registrars, hosts and payment providers. Court-order DNS blocking powers have been given to the Commission or are about to be; ISP blocking is not in operation as a routine measure. Writing “legal to use” about an unlicensed site is wrong on its face. The honest framing is that licensed sites offer British consumer protection and unlicensed sites do not.

Frequently Asked Questions

What is matched betting?

Matched betting is a technique for extracting value from bookmakers’ free bets and promotions by placing a back bet at the bookmaker and a lay bet against the same outcome at a betting exchange. The two bets settle against each other and the bettor ends close to even after commission, with a small profit margin equal to the free bet’s value minus the qualifying loss. It is not a forecast of outcomes; it is a pricing exercise on the gap between the offer and the lay price.

Is matched betting legal in the UK?

Matched betting is legal in Great Britain. There is no statute that prohibits placing a back bet and a lay bet on the same event, and the Gambling Commission does not prohibit the practice. The legal frame around it is the Gambling Act 2005, the bonus cap in force since 19 January 2026 (wagering capped at 10x), the no-mixed-product rule of the same date, the credit-card ban in force since 14 April 2020, and the GAMSTOP coverage that every GB-licensed online operator has joined since 31 March 2020. Bookmakers may restrict accounts they judge unprofitable; the technique is legal, but staying welcome is the bettor’s problem.

What is “no risk” matched betting?

“No risk” matched betting is the marketing language for a fully hedged trade where the back bet at the bookmaker and the lay bet at the exchange cover each other so that the outcome produces roughly equal returns either way. The qualifier “no risk” is approximate: the qualifying bet absorbs a small expected loss through the spread between the bookmaker’s back price and the exchange’s lay price and through the exchange’s commission on net winnings. The free bet’s value minus that loss is the profit, not the absence of loss.

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

Since 19 January 2026 wagering requirements on bonuses at GB-licensed operators are capped at 10x the bonus value. A £10 bonus at the old 50x would have demanded £500 of qualifying bets; under the cap no more than £100 of qualifying bets is allowed. Whether the cap applies to free bets with no wagering condition, and any cap on the money value of a bonus, are not established in the Commission’s published material.

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

The minimum odds set the floor at which the qualifying bet (and often the free bet) can be placed; below the floor the bet does not count toward unlocking the offer. The wagering requirement is the multiple of the bonus the bettor has to stake in qualifying bets before the bonus or its winnings become withdrawable. A 10x wagering requirement on a £10 bonus means £100 of qualifying bets at or above the minimum odds, before any of the bonus-related balance can be withdrawn. Under the 19 January 2026 cap no GB-licensed operator can set a wagering requirement above 10x.

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

Because that is the standard British free-bet shape. The operator credits the bettor with the free bet’s face value as a stake, settles the bet at the odds used, and pays the winnings (face × (odds − 1)) without returning the stake. A £30 free bet at decimal 1.90 (9/10) pays £27 on a win and nothing on a loss; the £30 is not refunded either way. The shape is what makes the offer’s expected value the face amount times the implied edge at the odds used, rather than the face amount itself.
