Editorial policy
How we research, write, date, check and correct every page on Top Casino Bonus UK, and how advertising is kept separate from our editorial judgement.

Our research standards
This policy explains how the Top Casino Bonus team researches, checks, writes and updates the site. The aim is simple: every page should be accurate, dated and fair, and readers should be able to check our sources for themselves.
- Primary sources first: casinos' own terms and help centres, the Gambling Commission, GOV.UK and the CMA, the ASA and CAP codes, legislation.gov.uk, HMRC and developers' game pages.
- Accuracy over completeness: if a figure such as a payout time, minimum deposit or RTP can't be confirmed, it is left out and readers are told where to check.
- No invented experience: pages are written as researched explanation, never as an account of deposits, sessions or withdrawals we made.
- No invented numbers: no made-up statistics, reviews, quotes or ratings.
- Every rule is dated, so readers can see when it took effect.
Who does the work is described on our editorial team page.
How offers, licences and rules are checked and dated
Different kinds of information change at different speeds, so each is checked in its own way and carries its own date.
| Information | How it is checked | Date shown |
|---|---|---|
| Partner offers and key terms | Against the casino's promotion page and full terms | Offers last checked 5 October 2026 |
| Licence holder and account number | On the Gambling Commission's public register | Checked with the offer |
| UK rules | Against the Commission's licence conditions, standards and news, and GOV.UK | The date each rule took effect, such as 19 January 2026 for the 10x wagering cap |
| Payment and withdrawal details | Against each casino's help centre | Checked with the offer |
| Page as a whole | Reviewed for accuracy and compliance | Pages updated 21 October 2026 |
Licences can be confirmed by anyone on the Gambling Commission's public register (opens in a new tab). For rules, we link to the official announcement, such as the Commission's news on safer and simpler gambling promotions (opens in a new tab).
How we work out bonus values
We turn offers into pounds so they can be compared fairly. Two calculations do most of the work. The value of free spins is the number of spins × the stake per spin, so 100 spins at 10p are £10 of spins. The average cost of wagering is the wagering total × the house edge, so a £50 bonus with 10x wagering needs £500 of bets, which at a 4% house edge costs about £20 on average.
These figures are illustrations, not predictions. RTP and house edge are long-run averages across very large numbers of bets. Any one session can end well above or below the average, and many end with nothing to withdraw. A bonus doesn't change a game's odds, and it doesn't make gambling cheaper or safer over time. We say this wherever we show the sums, and we never describe a bonus as a way to make money.
Readers can run their own figures through the wagering calculator.
The simple sums leave some things out, and pages say so where it matters. A ceiling on what bonus winnings can be withdrawn caps the best outcome. Games that count at less than 100% towards wagering raise the real amount of play needed. A maximum bet and a short deadline limit how the bonus can be used. Each of these makes an offer worth less in practice than its headline, and we point them out rather than quote the headline alone.
Slot figures and RTP versions
When a page gives a slot's RTP, volatility or maximum win, the team aims to check it against the developer's own information. That is a working standard rather than a guarantee: developers update their pages, and some supply casinos with more than one RTP version of the same game. Push Gaming's Big Bamboo, for instance, has a published RTP of 96.13%, and a 94.13% version also exists.
Because a casino can run a different version from the one a developer advertises, we tell readers to check the game's help screen before playing. UK rules require the RTP or likelihood of winning to be available before play, so the help screen is the figure that applies at that casino. Where a figure can't be confirmed, the page leaves it out.
Ratings, independence and affiliate disclosure
Casino ratings follow a published method that weighs an offer's value against its terms, how clearly those terms are written, payment exclusions, withdrawal information and the safer gambling tools available. The full method is on how we rate casino bonuses. Casinos can't pay for a score, a position or favourable wording.
The site is funded by affiliate commission: we may be paid when a reader signs up with a casino through our links. That never changes the maths on a page or our description of an offer's catches. The arrangement is explained on our advertiser disclosure, and it applies across the site.
Our wording follows the UK advertising codes, including the ASA's gambling code section (opens in a new tab). That means no hype, no pressure to act quickly, no suggestion that gambling solves money problems, and no use of ‘free’ without the condition that goes with it.
Responsible gambling commitments
- Gambling is presented as paid-for entertainment, with losses likely over time.
- Every mention of an offer includes 18+ and a reminder that terms apply.
- Pages about limits, self-exclusion, bank blocks and support carry no offers.
- Safer gambling tools such as deposit limits, time-outs, reality checks and GAMSTOP are explained as positives.
- We never give tips for getting round bonus terms or name unlicensed casinos.
Our safer gambling page lists free support, including the National Gambling Helpline on 0808 8020 133, run by GamCare (opens in a new tab), GAMSTOP and NHS gambling clinics.
AI-assisted drafting
Some pages are drafted with the help of AI tools. Every AI-assisted draft is reviewed by our editors before publication, and it goes through the same fact checks against primary sources and the same compliance review as any other page. Responsibility for what is published rests with the Top Casino Bonus team, not with any tool.
AI tools are not a source. Facts, figures, dates and offer terms on the site come from the primary sources listed in this policy, and anything a draft states that can't be traced to one of those sources is removed before publication.
Corrections and how often pages are updated
If we get something wrong, we fix it. Reports come through our contact page, and each is checked against the original source. When a correction is needed, the page is updated and its date changes. We would rather hear about an error than leave it in place, whoever reports it.
We don't update pages on a fixed timetable. Instead, pages are updated when something they depend on changes: a partner changes its offer or terms, the Gambling Commission or government changes a rule, or a source we rely on is revised. When a rule changes, every page it affects is revisited, which is how the 10x wagering cap from 19 January 2026 found its way into the worked examples across the site.
Frequently asked questions
When were the offers on the site last checked?
Partner offers and their key terms were last checked on 5 October 2026, and pages were updated on 21 October 2026. Casinos can change promotions at any time, so the terms on the casino's own promotion page always take priority over our summary. We revisit an offer whenever we learn it has changed, and the date shown on each page tells you when it was last reviewed. If you spot a difference, let us know through the contact page.
Are your bonus value figures predictions?
No. Our figures are illustrations based on long-run averages. We value free spins as spins × stake and estimate the cost of wagering as the wagering total × the house edge. Those averages describe what happens across very large numbers of bets, not what will happen to you. A single session can end well above or below them, and many end with nothing to withdraw. A bonus never changes a game's odds, and it doesn't make gambling cheaper over time.
Why do you tell readers to check a slot's help screen?
Because the help screen shows the version of the game that casino is running. Some developers supply more than one RTP version of the same slot, so the figure on a developer's page may not match every casino. Our team aims to check slot figures against the developer's own information, but that is a working standard rather than a guarantee. UK rules require the RTP or likelihood of winning to be available before play, so the help screen is the figure that applies.
Do you use AI to write pages?
Some pages are drafted with the help of AI tools. Every AI-assisted draft is reviewed by our editors before it is published, and it goes through the same checks as any other page: facts and figures against primary sources, offers against the casino's terms, and wording against the UK advertising codes and our responsible gambling standards. The Top Casino Bonus team is responsible for everything published on the site, however the first draft was produced.
How does affiliate commission affect your pages?
We may earn commission when a reader signs up with a casino through our links, and that is how the site is funded. It doesn't affect the maths on any page, our description of an offer's terms or the way ratings are calculated, and casinos can't pay for a better score. When a partner's offer has a catch, the page says so next to the offer. The full arrangement is set out on our advertiser disclosure.
How do you handle corrections?
Each report of an error is checked against the original source. If the page is wrong, we correct it and update its date. If the page is right, we can tell you which source it relies on. Corrections are handled the same way whether they come from a reader, a casino or another organisation, and the change must be supported by a published source. We don't change wording or ratings because someone asks us to. Use the contact page to send a report.
How often are pages updated?
There is no fixed schedule. Pages are updated when something they depend on changes: a partner alters its offer or terms, the Gambling Commission or government changes a rule, or a source we rely on is revised. When a rule changes, we revisit every page it affects. That is why the 10x wagering cap, in force since 19 January 2026, now appears in examples across the site. Each page shows the date it was last updated.
