A promo code is the bit of marketing around a free bet or a sign-up bonus that the page usually does not name. The word that sits behind it is the part a reader can weigh, and the part that decides whether the offer is worth a £10 qualifying bet or a £20 one. Codes change week to week, welcome offers change month to month, and the rules that govern them changed less than a year ago. Since 19 January 2026 the Gambling Commission has capped the wagering requirement on a sports bonus at ten times the bonus, and any offer that asks a customer to gamble on two or more product types — betting and casino in the same bundle, for instance — is out. That pair of rules is what makes 2026 different from the year before, and the rest of this guide reads against them.

A reader who treats a free bet as money already in the account gets the welcome offer wrong. The bookmaker’s marketing describes what the offer is on the day; the operator’s own terms describe what it costs. The gap between those two descriptions is the entire page.

Staying in control while chasing a welcome offer

A free bet credits the account, but the safer-gambling controls on that account run from day one. The Gambling Commission’s Remote Technical Standards require a gross deposit limit on a fixed time frame, and licensed operators offer loss limits and time-outs alongside it. A customer can set a daily, weekly or monthly ceiling themselves; the operator is required to make the controls visible and easy to find. None of this waits until the welcome offer has been turned over, because the controls are the licence condition, not a courtesy.

GAMSTOP is the national multi-operator self-exclusion scheme, and every online operator licensed by the Commission must take part. A self-exclusion can run for six months, one year, five years, or five years with auto-renewal. After the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. The scheme covers online sites and apps; betting shops use a separate service. Anyone who has registered with GAMSTOP cannot get past the signup wall of any GB-licensed bookmaker while the exclusion is live.

Identity checks come before the first deposit. Since 7 May 2019 a licensed operator has had to verify name, address and date of birth before a customer can deposit or gamble, and that includes staking a free bet or working through a bonus. A financial vulnerability check applies once deposits minus withdrawals exceed £150 in a rolling 30 days, in force since 28 February 2025; the check is a public-record one (a county court judgment, for example), not a credit reference check, and a refusal to undergo it does not void past bets but it can limit how the account is used thereafter. The Commission’s wider financial risk assessment — the press’s “affordability check” — has been announced in a staged plan, with no start date as of writing.

A credit card has been banned for gambling in Great Britain since 14 April 2020, and that ban reaches credit-card-funded payments through an e-wallet as well. A debit card, an instant bank transfer, Apple Pay, Google Pay, Revolut Pay and similar services are not covered. Anonymous play at a licensed site is no longer possible: the verification happens before the first penny goes in, and a free bet counts.

Anyone who feels the welcome offer is pulling them past the budget they set has three routes that do not require leaving the account. A reality check can pop up at fixed intervals during a session. A time-out stops the account for a chosen cooling-off window. GAMSTOP is the longer answer, with the duration the customer chooses and the seven-year tail that makes it stick. GamCare runs the National Gambling Helpline, and there is a network of NHS gambling clinics for face-to-face support; the Commission’s licence conditions point signposted customers toward both.

The single most expensive thing about a free bet is rarely the wagering requirement. It is the second bet the first one suggests.

How welcome offers and free bets actually work

What a free bet really pays back

A free bet is a token, not a cash credit. The stake of a free bet is almost never paid back with the winnings: at 3/1 odds, a £10 free bet returns £40 in profit, not £50, because the £10 stake disappears with the bet. The qualifying bet is a different animal. To claim a “bet £10, get £30 in free bets” type of offer, the customer places a £10 bet with their own money at the minimum odds the operator sets, settles that bet, and the free bet tokens drop in afterwards. The qualifying bet’s stake is paid back in the usual way if it wins; the free bet tokens, when staked, are not.

A free bet’s expiry matters as much as its size. The tokens have a clock attached. Seven days from issue is a common expiry; some operators stretch it further, others tighten it. A free bet won but not staked by the deadline is forfeited, and the operator’s terms say so plainly. The expiry is set by the operator, not by the Commission’s cap.

A free bet may also carry a minimum-odds rule on what it can be staked on. An each-way free bet pays two equal stakes from the same token, so the token’s value halves per leg. A free bet can almost never be combined with another free bet on the same selection. Some free bets are not allowed on certain markets at all — the operator’s terms list them.

A “risk-free” first bet is usually a free bet by another name. If the qualifying bet loses, the refund is paid as a free bet token rather than as cash, and the same rules apply: stake not returned, expiry applies, minimum odds apply. The bookmaker is never out of pocket on the refund, because what the customer wins on the token is theirs only after the next bet settles.

Wagering requirements, minimum odds and expiry

A wagering requirement is the amount of betting the operator requires before a bonus is released as withdrawable cash. A bonus that carries a wagering requirement is a credit, not a gift. The Commission’s cap, in force since 19 January 2026, is ten times the bonus. A £10 bonus at 50x needed £500 of bets before withdrawal; under the cap, no more than £100. The cap applies to the bonus element, not to the deposit.

Minimum odds are the floor below which a stake does not count towards the turnover. A wagering requirement of 10x on a £20 bonus with a £5 minimum stake at minimum odds of 2.00 (1/1) means at least £200 of bets at evens or longer, settled, before the bonus becomes cash. A bet at 1.80 does not count. A bet that is voided does not count. A bet settled with a Rule 4 deduction may or may not count, depending on the operator’s terms.

Expiry applies to the wagering window as well as to the free bet token. A 7-day wagering window is short. Twenty bets at £10 each clear a £100 turnover, but only if twenty bets get placed in seven days; the average reader, betting on weekends only, is half-way there in two weekends, and the deadline closes before the third. A 30-day window gives room to breathe.

What the 2026 promotion rules actually changed

Two rules, both in force since 19 January 2026, drew a line through a slice of marketing the industry had used for years. First, wagering requirements on bonuses are capped at 10x. Second, mixed-product promotions are banned. A mixed-product promotion is an offer that requires gambling on two or more product types in the same bundle — sports betting and casino together, sports and bingo together, betting and lottery together. The classic “bet £10 on football, get 50 free spins” landing page is out.

Whether the 10x cap applies to a free bet that carries no wagering condition is not established by the Commission’s published guidance. A token with no turnover attached is in a different category from a bonus that has to be turned over, and the rule as written speaks to the second. Until the Commission or a licensee clarifies, the safe reading is that a token with no wagering requirement attached sits outside the cap; the safe test for a reader is to read the operator’s terms.

The Commission has not capped the money value of a bonus itself. A £100 bonus is still legal; what is illegal is a £100 bonus that asks for £5,000 of bets before it pays out.

Price boosts, accumulator insurance and loyalty free bets

A price boost raises the price of a specific market — a specific horse at a specific meeting, a specific player to score first — for a window of hours. The boost is the operator’s money; the stake, if the bet wins, is paid back in the usual way. A boost from 5/1 to 7/1 on a £10 stake returns £80 in profit, not £80 plus the original stake as a free bet would.

Accumulator insurance refunds a losing accumulator as a free bet if one leg lets the side down. A stake of £5 on a five-fold acca at combined odds of 12/1, settled with one selection voided, returns the £5 stake as a free bet token if the operator’s acca insurance applies and the bet loses for that reason. The refund is almost always a free bet, not cash, and it carries an expiry and a cap. BoyleSports’s acca insurance, for instance, refunds a maximum of £20 as a free bet expiring in 7 days.

A loyalty free bet is a token for existing customers rather than new ones. The operator’s terms carry the specifics: minimum odds, eligible markets, expiry. William Hill’s Football Acca Boost runs on accas of two or more legs with each selection at 1/5 or bigger, scaling from a 3% boost on a double to 200% on twenty or more legs, with a £10,000 maximum boost per online bet; the promotion runs until 30 May 2027.

The arithmetic behind a bonus in 2026

The arithmetic belongs to the reader. Take Coral’s welcome offer: a £20 deposit and sports bet at minimum odds of 2.0 (1/1) returns £40 in free bets within 7 days, the free bets themselves expiring 7 days after issue. The wagering requirement is zero, because the £40 is in free bets rather than in bonus credit. Under the Commission’s 10x cap, a £40 bonus with a 10x turnover would have required £400 of qualifying bets at minimum odds; with no turnover attached, the £40 is paid out as tokens and the cost of clearing the offer is whatever the tokens lose when staked.

Take Sky Bet’s welcome offer instead: three £10 free bet tokens credited after a first single or each-way bet of at least 5p at minimum odds of 1/1. The qualifying bet is the 5p stake, not a £5 stake; the offer asks for less of the reader’s own money than its headline suggests. Three tokens at £10 each, with stake not returned, on selections of the reader’s choice, is a credit of up to £30 in profit, with the cost measured by what those selections lose on average rather than by a turnover.

Take Hollywoodbets’ sports welcome offer: stake returned as a free bet of up to £30 on a first qualifying losing accumulator with at least three legs, combined odds of 4/1 or greater, settled within 7 days. The token is contingent on a loss. The reader needs an acca that loses to claim, which is the structural shape of a stake-back rather than a free-bet credit. The cost is the £10+ stake on a losing acca; the upside is the £30 token, with the same rules any free bet carries.

The number that decides whether any of this is worth a qualifying bet is the reader’s own budget, the deadline attached to the token, and the minimum odds the operator sets on what the token can stake. None of those numbers is on the landing page. They are in the terms, and the terms are what the offer is.

The ten bookmakers in this comparison

A welcome offer is one thing a reader sees on the homepage; the licence is the thing the regulator has put on the public register, and the two are not the same. Every bookmaker named here is on the Gambling Commission’s public register as a holder of a remote general betting licence for Great Britain, which means the customer-protection regime applies — GAMSTOP membership, identity verification before the first deposit, the 10x bonus cap, the £150 financial vulnerability check, and a complaints route through an approved dispute-resolution body. A licence is not a ranking, and a position on a shortlist is not a licence: there are more licensed brands than any comparison can name, and the Commission’s register is the only test of whether one is licensed at all.

Reading the licence number in the table

A Gambling Commission account number sits next to every brand above. Five digits, sometimes six, attached to a licensee whose legal name is on the Commission’s public register. The account number is searchable: a check on the Commission’s register by business name, trading name, domain or account number will confirm whether the brand holds a remote general betting licence for Great Britain and which legal entity holds it. The licence number printed in marketing material is sometimes the operator’s full remote operating licence, with its suffix; the table above uses that fuller form. A brand on the register at one date may have a different account number the next; the register itself is the test, not the marketing material.

The licence type matters. Remote general betting standard (real events) is the category a sports bookmaker holds. Remote general betting standard (virtual events) covers computer-simulated events. Remote pool betting covers pool bets on horse or dog racing. Remote betting intermediary is the exchange licence. The Commission keeps each category separate, and an exchange is not licensed as a sports bookmaker, nor vice versa.

Several brands can run under one licensee. Ladbrokes and Coral sit on the same Group structure; Paddy Power and Betfair do too. Two brands on the register against one licensee are not two licences; they are one licence and two trading names. The Commission’s register shows the legal entity and the trading names it operates, which is why a quick search by brand is the right first move.

The same holds offshore. A brand licensed in Malta or Curaçao, or in Gibraltar, is not licensed by the Commission unless the register shows it, and a brand licensed elsewhere cannot advertise a GB-facing service without a Commission licence at the point of consumption. Since the Gambling (Licensing and Advertising) Act 2014, an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based. A foreign licence is not a substitute.

A primer on how the betting market is shaped

The betting market in Great Britain is not a single thing. It is several licensed categories that share a regulator and a customer-protection regime but have different products, different duty rates and different licence types. A reader who treats the market as one homogenous offering gets the protections wrong as well as the offers.

What a bookmaker’s licence actually permits

A remote general betting standard (real events) licence lets the holder offer fixed-odds betting on real sporting events, politics, TV shows and novelty markets — within the operator’s own house rules and the Commission’s Licence Conditions and Codes of Practice. There is no statutory list of permitted bets. An operator holds the licence, then chooses what to offer under it, and the LCCP’s social responsibility code is the backstop for what a customer is allowed to do with the account.

In-play betting is part of the offering at most major GB bookmakers. The control is the operator’s licence condition and the customer’s safer-gambling controls, not a separate statutory cap. The Commission’s published position is not that in-play is “unrestricted”; the position is that in-play is offered subject to the operator’s licence conditions and customer-protection duties. A reader who wants to limit in-play on their account can do so through a product block or a stake limit; the operator is required to make that possible.

Esports sit inside the same licence category as any other real event. Virtual events — computer-simulated horse races, football matches and the like — are a separate licence category, with a separate duty treatment and a separate set of LCCP conditions. Pool betting on horse or dog racing is a third. A spread betting product on a financial market is not a Commission licence at all; it is the Financial Conduct Authority’s domain, and the rules on leverage and margin are FCA rules rather than Commission ones. A spread bet on a sports index, by contrast, sits under the Commission’s general betting regime and pays General Betting Duty, not the FCA’s spread-betting rate.

The shape of the consumer side

The customer-protection regime is the same across all remote general betting standard licences, and it is the second layer of the offer behind the headline. Identity is verified before the first deposit. A gross deposit limit is offered on a fixed time frame, and the customer chooses the ceiling. GAMSTOP runs as a backstop, and a customer who has self-excluded cannot open an account at any licensed online operator for the duration they chose plus the seven-year tail. The financial vulnerability check fires once deposits minus withdrawals exceed £150 in a rolling 30 days. The financial risk assessment is staged, with no start date as of writing.

The complaint path runs through the operator first and through an ADR body if the operator’s response does not resolve the dispute. Approved ADR bodies are listed by the Commission. Beyond ADR, an unresolved complaint can be referred to the Commission itself, although the Commission’s role is regulatory rather than a refund mechanism. Funds held by an unlicensed operator have no equivalent route: there is no ADR body the Commission approves for offshore brands, no GAMSTOP coverage and no British consumer redress if funds are withheld.

What the price actually contains

A bookmaker’s price contains a margin. The margin is the share of every unit bet on a market that the bookmaker keeps on average across all outcomes; the rest is paid back to winning customers. For a two-outcome market priced at 5/6 and 5/6, the margin is roughly 9%; for a three-outcome 1X2 market priced at 6/4, 11/5 and 4/1, the margin lands higher. The exact figure depends on the event and the market, and the margin is not on the betting slip.

A reader’s edge is the difference between the margin and what their own estimate of the outcome would have priced. A bettor whose model gives a horse a 25% chance of winning and the bookmaker offers 4/1 (a 20% implied chance) has a positive edge; a bettor whose model gives the same horse 25% and the bookmaker offers 3/1 (25% implied) has zero edge before commission. Welcome offers are not part of the edge calculation: a free bet is a credit, not an estimate of probability, and the credit is what the reader weighs.

Price boosts narrow the margin by raising the price on a specific market. Accumulator insurance narrows the loss on a specific outcome but not on the others. Loyalty free bets are credits on a future stake. None of these alters the underlying margin of the markets they sit on top of, and the difference between a “boosted” market and an unboosted one is the boost, not the price.

The legal frame in plain terms

The Gambling Act 2005 covers Great Britain. Northern Ireland is outside the Act and has its own older law, so a Great Britain licence is a licence for England, Scotland and Wales, not for Northern Ireland. The Commission is a non-departmental public body sponsored by the Department for Culture, Media and Sport, and it is the regulator for the whole commercial market under the Act.

The minimum age is 18. The Commission’s identity check is required before a customer can deposit or gamble, and the same check applies to a free bet or bonus. The 2026 promotion rules sit on top of the Act, in the Commission’s Licence Conditions and Codes of Practice and the Remote Technical Standards that go with them. They are licence conditions; breaking them is a breach of licence, not a criminal offence aimed at the customer.

The bonus cap and the mixed-product ban

The bonus cap, in force since 19 January 2026, is ten times the bonus. A £10 bonus can ask for £100 of qualifying bets before payout; £50 of bonus would require no more than £500 of qualifying bets. The cap is on the bonus element, not the deposit, and the cap is on the wagering requirement, not the bonus value itself. A £100 bonus at 10x is legal; a £10 bonus at 50x is not. The bonus cap covers the turnover the operator requires. It does not cap the stake, the price, or the eventual winnings.

The mixed-product ban removes any bundle asking a customer to gamble on two or more product types in the same offer. Sports betting and casino together is the clearest example. Sports betting and bingo together is another. Lottery tickets bundled with a sports free bet is a third. The bundle itself is the offence; separate offers that the customer signs up to independently are not.

Whether the cap applies to free bets with no wagering condition is not established in the published guidance. A token with no turnover attached is a different instrument from a bonus that has to be turned over. Until the Commission or a licensee publishes a reading, the safe assumption is that the cap covers the second and not the first; the safe test is the operator’s own terms.

Tax and what the customer pays

The customer pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on gross profits, currently 15%, and from 1 April 2027 a new remote betting rate of 25% applies within it for remote bets other than on UK horse racing, while self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Until 1 April 2027 the remote rate stays at 15%, and whether operators pass duty on through odds is not established. A reader who is a professional gambler should ask HMRC or an adviser; the reader who is not owes nothing on winnings.

Spread betting on financial markets carries the FCA’s spread-betting regime, not the Commission’s. The rates are 3% on financial spread betting and 10% on other spread betting, and the customer’s liability is not capped at their stake. A spread bettor can lose more than they deposited. A fixed-odds customer cannot.

What an unlicensed site actually means

A GB licence is compulsory at the point of consumption. Providing gambling facilities in Great Britain without the licence the Act requires is an offence under section 33 of the Gambling Act 2005, with a sentence on summary conviction of up to 51 weeks’ imprisonment, a fine up to level 5, or both (six months in Scotland). The offence is aimed at the operator. The customer who merely bets on an unlicensed site is not, on the published face of the statute, committing an offence.

What the customer loses is the protection regime: no GAMSTOP coverage, no Commission complaints route, no approved ADR body for the brand, no British consumer redress if funds are withheld, no obligation on the operator to honour the 10x bonus cap or the £150 vulnerability check. The Commission’s enforcement is disruption rather than blocking: cease-and-desist notices, search-engine referrals, registrar and host and payment-provider work. The Commission has been given, or is about to receive, court-order DNS blocking powers; ISP-level blocking of unlicensed sites is not in operation as of writing.

The honest framing is that a licensed site is checked, limited and accountable, with the verification and the GAMSTOP membership that come with that; an unlicensed site is none of those things, and funds held offshore have no British route back if they are withheld. Neither is “the safe choice” by default. The reader’s job is to know which they are on.

Verdict on each bookmaker

Unibet — best for breadth of product

Unibet’s UK site has been live since 1999, and the breadth of the in-house and on-the-day product is the legacy of that. The sports welcome offer is “Get £40 in Free Bets when you bet £20” at minimum odds of 2.0 (1/1), tokens expire within 7 days of issue, and the qualifying deposit and bet must come from a debit card or an instant bank transfer. The platform also runs Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing and Cash Out on thousands of markets. For a reader who wants one account across sports, in-play and racing, with a £20 qualifying bet to claim, the offer is competitive and the surrounding product is wider than most of the comparison.

Paddy Power — best for novelty markets

Paddy Power’s app carries Bet Builder+, Popular Bet Builders, Super Sub (a bet rolls over to the replacement if a selected player is substituted), expanded Win More markets and player and ACCA stats. The brand’s reputation is for novelty markets and headline prices on Premier League and Champions League football. For a reader who bets on player props and on markets that do not exist at every bookmaker, Paddy Power is the name that tends to have them first.

Copybet — best for accumulator bonuses

Copybet’s Acca Booster pays up to a 100% cash bonus on accas of at least three selections, and the Daily Profit Boost tops out at 15%. A 100% cash bonus is more useful than a free-bet refund, because the stake is paid back with the cash bonus. For a reader who plays accumulators as their main bet, the boost structure rewards acca volume directly.

London Bet — best for a smaller product

London Bet is published by Thistle Bet Limited, holds a UK licence and carries a 17+ App Store age rating. The brand is smaller than the comparison’s bigger names, and the product range tends to focus on the British racing calendar and football. For a reader who wants a UK-licensed operator with a smaller menu, the brand sits in a quieter slot than the giants of the comparison.

Betway — best for a token-style welcome

Betway’s welcome offer is £40 in free bet tokens, credited as four £10 tokens on settlement of a first bet of at least £10 at minimum odds of 2.0, with a 7-day expiry and debit card deposits only. Four smaller tokens are more useful than one larger one for a reader who likes singles and short accas rather than one stake on a long-priced outsider. The 7-day expiry is tight; the four-token split gives a reader a chance to spread the credit across more than one bet.

10bet — best for a deposit-matched headline

10bet’s app advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins. A deposit-matched bonus carries a wagering requirement where a free-bet offer does not, and the 10x cap that took effect on 19 January 2026 is what makes a 100% bonus workable. A £50 bonus at 10x needs £5,000 of qualifying bets at minimum odds; the cap is the ceiling on that turnover, and any bonus over the cap is a breach. For a reader who wants a larger headline and is comfortable working through the turnover, 10bet is the comparison’s deposit-matched option.

BetVictor — best for ongoing boosts

BetVictor’s offer is structured around promotions rather than a headline welcome: regular price boosts, acca offers and free bets on selected events, with welcome offers shown in the app and governed by its customer terms and conditions. For a reader who already has an account elsewhere and is shopping for the day-to-day product, BetVictor’s ongoing boosts are the draw.

Hollywoodbets — best for stake-back structure

Hollywoodbets’ sports welcome offer returns the stake as a free bet of up to £30 on a first qualifying losing accumulator, with the acca needing at least three legs, combined odds of 4/1 or greater, settled within 7 days. One free bet per customer. The structure rewards an acca that loses, which is the higher-probability outcome on a 4/1 shot, and the £30 ceiling is the upside. For a reader who bets accas and is comfortable that a loss is what triggers the offer, the structure is the draw.

BetUK — best for football-specific credit

BetUK’s sports welcome offer is four £10 free bets, but the four are split: two are for football accas of 4+ selections and two are for multiples of 2+. Tokens are valid for 7 days. Opt-in is required. The football-specific carve-out is the unusual move; a reader whose accumulators are almost always on football gets more useful credit than the headline suggests.

Sky Bet — best for a low-cost qualifying bet

Sky Bet’s welcome offer is £30 in free bets, credited as three £10 tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at minimum odds of 1/1. The 5p minimum stake is the draw. For a reader who wants the credit without risking more than five pence on the qualifying bet, Sky Bet’s offer is the lowest-cost route in the comparison.

Calculating the cost of a sign-up bonus in 2026

The Commission’s 10x cap on wagering requirements is the single number that decides how much betting a bonus costs. A £10 bonus at 50x needed £500 of qualifying bets; under the cap, no more than £100. A £50 bonus at 10x needs £500 of qualifying bets; a £100 bonus at 10x needs £1,000. The cap is on the bonus element, not the deposit, and the cap is on the wagering requirement rather than the bonus value itself.

A useful worked example: take a 100% deposit-matched bonus of £50 at 10x with a £5 minimum stake at minimum odds of 2.00 (1/1). Required turnover is £500, the number of bets is turnover divided by stake — 100 bets at £5 each — and the window is whatever the operator sets. A 7-day window needs roughly 14 bets a day, which is not a pace a casual reader keeps; a 30-day window needs three to four bets a day, which is more workable. Bets at odds shorter than 2.00 do not count; settled bets at 2.00 or longer do. Each bet that fails to reach the minimum odds is, in effect, a wasted stake against the bonus’s £500.

The expected cost of clearing that bonus, assuming only the bonus amount is being turned over, is the turnover multiplied by the margin of the market the reader is betting on. A market with a 5% margin costs £25 in expectation over £500 of bets; a market with a 9% margin costs £45; a market with a 12% margin costs £60. The exact margin depends on which sport and which market the reader picks, and the reader’s choice of market is the variable that decides whether the bonus is cheap or expensive to clear.

A reader who already bets on a sport with a thin margin — outright winner on a Premier League match, for instance — is paying less to clear the bonus than a reader who bets on a market with a wider margin. A reader who picks short-priced favourites is paying the wide margin of favourites, not the thin margin of outsiders, and the bonus costs more to clear than the headline suggests.

The right way to think about a bonus under the 10x cap is as a credit that costs the reader the expected value of the bets needed to release it. A free bet with no wagering condition attached is a different instrument: it is a token whose cost is whatever the token loses when staked, and there is no turnover to clear. Under the cap, a 100% deposit-matched bonus at 10x is the most aggressive offer the reader can expect to see, and a free bet with no wagering condition sits outside the cap on the published guidance.

State the result as a band rather than a single figure. A £50 bonus at 10x on a market with a 5% margin costs around £25 in expectation; on a 9% margin, around £45; on a 12% margin, around £60. The reader’s market choice is what moves the answer.

Frequently asked questions about UK bookmaker promo codes

How do you use a promo code at a UK betting site?

A promo code is entered at the signup stage or in the cashier, depending on the operator. The code credits the offer the code is attached to: a free-bet sign-up, a deposit match, a price boost. The code itself is a string of characters; the offer it unlocks is described in the operator’s own terms, including the minimum odds, the qualifying stake, the expiry and whether the code is a one-off or recurring. The Commission’s 10x cap on wagering requirements and the mixed-product ban govern what the offer can be; the operator’s terms govern what the code actually pays.

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

Ten times the bonus. Since 19 January 2026, the Gambling Commission has capped wagering requirements on sports bonuses at 10x. A £10 bonus can ask for no more than £100 of qualifying bets; a £50 bonus can ask for no more than £500. The cap covers the wagering requirement rather than the bonus value, and a free bet with no wagering condition attached sits outside the cap on the published guidance.

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

The minimum odds are the floor below which a stake does not count towards the wagering requirement. A bonus with a wagering requirement of 10x and minimum odds of 2.00 (1/1) means each qualifying bet must be at evens or longer. The wagering requirement is the total amount of qualifying bets the operator requires before the bonus becomes withdrawable cash; a £20 bonus at 10x is £200 of qualifying bets at minimum odds, settled, before the £20 is cash. A bet at 1.80 does not count; a voided bet does not count.

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

A free bet is a token rather than a cash credit. The operator’s terms say the stake of a free bet is not returned, which means a winning £10 free bet at 3/1 returns £40 in profit rather than £50 (stake plus profit). The token’s value is the winnings, not the stake-plus-winnings, and the operator’s risk on the offer is capped at the bonus value. A “risk-free” first bet that refunds a losing stake as a free bet rather than as cash works the same way.

Can a sports bet be tied to a casino bonus under the 2026 promotion rules?

No. Since 19 January 2026 the Commission has banned mixed-product promotions, which are offers that require gambling on two or more product types — sports betting and casino together, sports betting and bingo, betting and lottery. An offer that asks a customer to bet £10 on football to get 50 free spins is out. Separate offers that a customer signs up to independently are not bundled, and the ban does not reach them.

How can a bookmaker’s Gambling Commission licence be checked?

The Commission’s public register is searchable by business name, trading name, domain or account number. A search by the brand name returns the licence holder, the account number and the licence category. The register is the test of whether the brand holds a remote general betting licence for Great Britain; a foreign licence is not a substitute, and the Gambling (Licensing and Advertising) Act 2014 requires a Commission licence wherever the operator is based. A licence number in marketing material is the operator’s full remote operating licence, with its suffix.
