UK casino bonus rules A–Z
Every rule that shapes casino bonuses in Great Britain, in plain English, with the date it started and what it means when you claim an offer.

UK casino bonus rules: who sets them and why
UK casino bonus rules come from four places, and knowing which one applies helps you understand what a casino can and can't put in its terms. The Gambling Commission sets licence conditions and codes of practice (the LCCP) and technical standards for games. Consumer law, enforced by the Competition and Markets Authority (CMA), makes unfair terms unenforceable. The advertising codes, written by CAP and policed by the ASA, control how offers are promoted. Parliament sets the framework through the Gambling Act 2005, and HMRC sets the duties operators pay.
The rule pages listed on this hub each take one of those rules, quote what it actually says, date it, and explain what it means for a bonus in pounds. They are written for players, not lawyers, and they link to the official source so you can read the original wording yourself.
The common thread is protection rather than generosity. The rules exist to keep offers clear and fair and to stop incentives encouraging harmful play. None of them makes gambling a way to earn money, and a bonus that follows every rule still carries the house edge of the games you play.
The main UK casino bonus rules at a glance
| Rule | What it says | In force since | Read more |
|---|---|---|---|
| 10x wagering cap | Wagering can't exceed 10 times the bonus (LCCP SR code 5.1.1) | 19 January 2026 | 10x wagering cap |
| Mixed-product ban | One incentive can't cover more than one product, such as betting and casino | 19 January 2026 | Mixed-product ban |
| Withdraw your deposit | You can withdraw your own deposit balance at any time, even with a bonus active | CMA undertakings, 2018 | CMA bonus principles |
| Significant terms up front | Key conditions must be shown with the offer, full terms one click away | LCCP 5.1.9; CAP 8.17 | Significant conditions in ads |
| Slot stake limits | £5 per spin for 25+, £2 for 18–24 | 9 April and 21 May 2025 | Slot stake limits |
| Bonuses stop on harm | No marketing or new bonuses for customers with strong signs of harm | 12 February 2023 | Bonuses and harm indicators |
| Credit card ban | No gambling on credit cards, including via e-wallets | 14 April 2020 | Credit card ban |
The Commission explained the 2026 changes in its news release making gambling promotions safer and simpler (opens in a new tab). An outright ban on wagering was consulted on but not adopted; the 10x cap was chosen instead.
Rules also stack on top of each other, and the strictest one wins. If a bonus sets a £5 maximum bet on slots, a player aged 25 or over is held to £5 by both the terms and the law, while a 21-year-old is held to £2 because the legal limit for 18 to 24-year-olds is lower. In the same way, age and identity must be verified before anyone can deposit or play, including with a bonus, a rule in force since 7 May 2019, and that applies to free-to-play demo games too. No bonus term can switch off a legal requirement.

What changed in UK bonus rules in 2025 and 2026
Most of the rules on this hub trace back to the government's 2023 white paper, ‘High stakes: gambling reform for the digital age’. Its proposals arrived in stages, and the last two years brought the biggest changes to how bonuses work since the CMA's action in 2018.
| Date | Change |
|---|---|
| 17 January 2025 | Game design rules (no autoplay, minimum game speed) extended from slots to other online casino games |
| 28 February 2025 | Financial vulnerability check threshold lowered to £150 net deposits in 30 days |
| 6 April 2025 | Statutory levy began; unfair commercial practices provisions of the DMCC Act 2024 in force |
| 1 May 2025 | Marketing consent required per product and per channel |
| 31 October 2025 | Financial limit prompt before the first deposit |
| 19 January 2026 | 10x wagering cap and mixed-product ban in force |
| 1 April 2026 | Remote gaming duty paid by operators rose from 21% to 40% |
| 30 September 2026 | Deadline for casinos to offer gross deposit limits |
Some proposals have not happened. Financial risk assessments using credit-reference data were piloted but are not live, and no decision had been made by October 2026. No gambling ombudsman has been created. The full sequence back to 2005 is on the bonus rules timeline, and the remote gaming duty page explains why the tax rise doesn't touch players' winnings.
Your rights under consumer law
Licence condition 7.1.1 requires casino terms to be fair and transparent under the Consumer Rights Act 2015. Under section 62 of that Act (opens in a new tab), an unfair term isn't binding on you, and where a term could mean two things, the meaning most favourable to the consumer wins. The CMA's investigation, which ran from 2016 to 2019, turned those principles into specific commitments from operators.
- A casino can't vary or withdraw a promotion you've opted into, except to prevent fraud or similar unlawful behaviour.
- Prohibited types of play must be spelled out in advance; a casino can't keep sole discretion to decide what breaks the terms.
- Un-staked deposits remain yours and can't be confiscated.
- You can't be required to take part in publicity to keep a win.
- Withdrawal limits can't cap what you take out of your deposit balance.
The Commission enforces these points. In July 2025 it fined Taichi Tech £170,000, partly over a term allowing it to close accounts or forfeit winnings at its discretion. Our pages on unfair terms under the Consumer Rights Act and the 2018 CMA undertakings go further.
How to use the rule pages
The cards group the rules by theme: promotions and terms, game and stake limits, safer gambling, advertising, tax and duty, and complaints. Each page follows the same order, so it is easy to move between them.
- Start with the rule that matches the term you're unsure about, such as wagering, a max bet or a payment exclusion.
- Read the ‘what it says’ section, which quotes or closely summarises the official wording and its date.
- Work through the example to see what the rule means in pounds.
- Check the ‘what it doesn't cover’ section; many rules apply only to Great Britain or only to certain games.
- Follow the link to the official source if you need the exact text.
If you meet an unfamiliar term along the way, the casino bonus glossary defines it, and the casino bonus guides turn the rules into practical how-tos.
Applying the rules when you read a bonus offer
A quick check against the rules will catch most problems before you sign up. Wagering above 10x on a UK-licensed site is not allowed. An offer that needs a sports bet to earn casino spins breaks the mixed-product ban. A significant term such as an excluded payment method should appear with the offer, not only in the full terms; the ASA's guidance on free bets and bonuses (opens in a new tab) lists what counts as significant.
If something goes wrong, complain to the casino first. It has eight weeks to resolve the complaint, after which it must offer a free alternative dispute resolution (ADR) service such as IBAS. The Commission's guide on how to complain (opens in a new tab) sets out the steps, and our complaints and ADR page explains the time limits.
These rules cover Great Britain. Northern Ireland has its own, older law, explained on Northern Ireland gambling law.
Frequently asked questions
Who regulates casino bonuses in the UK?
The Gambling Commission regulates casino bonuses in Great Britain through licence conditions and codes of practice, including the 10x wagering cap. Consumer law also applies, so unfair bonus terms can be challenged under the Consumer Rights Act 2015, with the CMA as the main enforcer. The ASA enforces the advertising codes that control how offers are promoted. Northern Ireland sits outside the Commission's remit. Our who regulates casino bonuses question explains how the bodies divide the work.
What is the maximum wagering requirement in the UK?
The maximum is 10 times the bonus amount, a rule in force since 19 January 2026 under LCCP social responsibility code 5.1.1. A £20 bonus can therefore require no more than £200 of bets before bonus winnings become withdrawable. The cap applies to bonus funds, not to your own deposit, which you can always withdraw. Before 2026, requirements of 35x or more were common. The 10x wagering question explains what the cap means in practice.
Are casino bonus terms legally binding?
Fair terms are binding, but unfair ones are not. Under section 62 of the Consumer Rights Act 2015, a term that causes a significant imbalance to the consumer's detriment, contrary to good faith, doesn't bind you, and unclear wording is read in your favour. Gambling Commission licence condition 7.1.1 also requires casinos to keep to their own terms. Clear restrictions, such as a stated maximum bet, are generally enforceable, so read them before you play. See are bonus terms legally binding.
Can a casino change bonus terms after I opt in?
Generally not. Gambling Commission guidance says operators must not use terms that let them vary or withdraw a promotion for a customer who has already opted in, unless that is needed to prevent fraud or similar unlawful behaviour. Material changes to general terms must be notified before they take effect. If a casino changes an offer you have already accepted, ask for an explanation in writing and use its complaints process. Our question on changing terms has more.
Did the 2026 rules ban wagering requirements?
No. The Gambling Commission consulted on an outright ban but chose a cap instead. Since 19 January 2026, wagering can't exceed 10 times the bonus, and promotions that mix products, such as sports bets that earn casino rewards, are banned. An offer still can’t be changed or made bigger because you reach the qualifying spend faster. No-wagering offers remain common because casinos choose them, not because the law requires them. The bonus terms after January 2026 page compares the old and new positions.
Do I pay tax on casino bonus winnings?
No. Gambling winnings, including winnings from bonuses and free spins, are not taxed for UK players. HMRC's business income manual says betting and gambling as such are not trading. The tax side falls on operators instead: remote gaming duty rose from 21% to 40% of their profits on 1 April 2026. That change doesn't alter your winnings, though it may affect what offers operators choose to run. Our gambling winnings tax page has the detail.
Do UK bonus rules apply in Northern Ireland?
Not in the same way. The Gambling Act 2005 and Gambling Commission rules cover Great Britain. Northern Ireland's gambling law is the Betting, Gaming, Lotteries and Amusements (Northern Ireland) Order 1985, amended in 2022, and it has no full framework for online gambling. Some UK welcome offers exclude Northern Ireland altogether. Don't assume protections such as the 10x cap or ADR access apply there in the same form. Our Northern Ireland guide explains the gaps.
What happens when a casino breaks the bonus rules?
The Gambling Commission can fine an operator, impose licence conditions or suspend its licence, and it publishes enforcement action on its website. For an individual dispute, the Commission doesn't resolve complaints itself. You complain to the casino first; after eight weeks without a resolution it must offer free alternative dispute resolution. IBAS, one approved provider, has operators agree to be bound by decisions up to £10,000. See how UKGC fines relate to bonuses for examples.
Are affordability checks part of the bonus rules?
Not as such. Credit-reference-based financial risk assessments were piloted but are not live, and the Commission says the term ‘affordability check’ is inaccurate. What does apply, since 28 February 2025, is a financial vulnerability check using public records such as bankruptcies and county court judgments when net deposits pass £150 in a rolling 30 days. Separately, casinos must stop new bonuses for customers showing strong signs of harm. Our financial vulnerability checks page explains the threshold.
