UK advertising codes: CAP 16

What the UK advertising codes CAP 16 section is

The Committee of Advertising Practice (CAP) writes the UK Code of Non-broadcast Advertising and Direct & Promotional Marketing, usually called the CAP Code. Section 16 is its gambling chapter. The Advertising Standards Authority (ASA) enforces it, investigating complaints and publishing rulings that name the advertiser. You can read the full text on the ASA’s CAP Code section 16 page (opens in a new tab).

Section 16 applies to marketing for gaming, betting and other activities that count as gambling under the Gambling Act 2005, plus spread betting. Lotteries have their own chapter (section 17 of the CAP Code). Broadcast adverts on TV and radio sit under a parallel rulebook, the BCAP Code section 17 (opens in a new tab), so a casino’s Saturday-night TV spot and its Instagram post are judged under two sets of rules that say much the same thing.

The section covers operators licensed in Great Britain and anyone marketing on their behalf, which explicitly includes affiliates. That means a comparison site describing a welcome offer is held to the same standards as the casino’s own banner. It is one of several overlapping layers of UK casino bonus rules: the Gambling Commission sets licence conditions, the CMA polices consumer law, and CAP and the ASA police the advert itself.

CAP Code rules are not an Act of Parliament. They are self-regulatory, but they have teeth: the Gambling Commission makes compliance with them a licence condition, so an ASA ruling against a casino can feed into Commission action.

CAP 16 rules one by one: 16.1 to 16.3.17

The core of the section is rule 16.1, which says gambling marketing must be socially responsible, with particular regard to protecting children, young persons and other vulnerable people from harm or exploitation. Rule 16.2 adds that both the spirit and the letter of the section apply even when an ad doesn’t show or mention a gambling product, which catches brand ads and sponsorships.

Rule 16.3 then lists seventeen things gambling marketing must not do. The wording below is a plain-English summary, not the code text.

Rules 16.4 and 16.5 deal with venues: ads for family entertainment centres, racecourses and similar places that only mention gambling in passing may show children if they are with an adult in areas the law doesn’t age-restrict, and ads for events you can only reach by walking through gambling premises must say so.

The strong appeal test and the under-25 rule in CAP 16

Two rules do most of the day-to-day work. Rule 16.3.12 has applied since 1 October 2022, when it replaced the older test of ‘particular appeal’ to under-18s. Under the old wording an ad only broke the rule if it appealed more to children than to adults. Under the new one, an ad breaks it if it is likely to strongly appeal to under-18s at all, even if adults like it just as much. The ASA’s advice on betting and gaming appeal to children (opens in a new tab) explains how it judges this.

The code also bars anyone whose example under-18s are likely to follow, or who strongly appeals to them, from appearing. There is a narrow exception where an operator has taken steps to limit appeal to under-18s, which allows gambling ads linked to sports or video games that young people like, as long as the creative itself isn’t aimed at them.

Rule 16.3.14 sets the 25+ rule. Nobody who is, or seems to be, under 25 may be shown gambling or playing a significant role. People aged 18 to 24 may appear in a significant role only where a bet can be placed directly, such as an operator’s own site, and only in a betting context. CAP and BCAP updated their guidance on protecting under-18s on 14 October 2025.

Why this matters for casino bonus pages

Slot artwork is often bright and cartoon-like. A bonus page that leans on cute characters, meme language or influencer styling can fail the strong appeal test even if every number on the page is correct. That is why responsible bonus pages, including this site’s, describe slots by their maths and terms rather than by playful mascots.

How CAP 16 works with section 8 on bonus terms and ‘free’ claims

Section 16 sets the social-responsibility tone, but most complaints about casino bonuses are decided under section 8, the promotional marketing chapter, and section 3, on misleading advertising. CAP’s guidance on gambling promotions says both section 16 and section 8 apply to every bonus ad.

• CAP 8.17: significant conditions must be stated clearly and prominently wherever leaving them out is likely to mislead. For gambling, the ASA treats eligibility (new customers, age, location), deposit and wagering requirements, time limits and bet restrictions as significant.
• CAP 3.23 and 3.24: an offer can only be called ‘free’ if the consumer pays nothing beyond the unavoidable cost of responding, and the ad must make clear what commitment is needed. The ASA guidance on free bets and bonuses (opens in a new tab) says operators should not call an offer ‘free’ if customers must risk their own money to qualify.
• Full terms: online ads must link to the full terms no more than one click away, through clear links rather than footers or small print.

In practice this is why compliant offers read ‘Bet £10 on slots, get 100 free spins’ rather than ‘100 free spins’. The qualifying spend sits next to the word ‘free’. For a deeper look, see our pages on ‘free’ in gambling ads and significant conditions in ads.

CAP 16 in practice: worked bonus ad examples in pounds

The easiest way to see the codes at work is to compare wording. The examples below are illustrations written for this page, not real adverts.

Numbers matter too. Take a £20 deposit that earns a 50% bonus of £10 with 10x wagering. The ad has to make clear you need £100 of bonus wagering (10 × £10) within the stated period. On a slot with a 4% house edge, that wagering costs about £4 on average (£100 × 4%), so the bonus is worth roughly £6 in expected terms before any max-bet or game restrictions. An ad that showed only ‘£10 bonus’ would leave out the very condition that shapes its value. Our wagering requirements guide walks through the same maths for other offers.

ASA rulings on casino bonus ads under the UK codes

Published ASA rulings show how the codes are applied to promotions. A few that bear directly on casino and betting bonuses:

The Apollo Entertainment ruling (opens in a new tab) is a useful reference because it involved a casino welcome bonus. A 60x requirement on £1,500 would have meant £90,000 of wagering, a fact the email never mentioned. Since 19 January 2026 such a requirement could not be offered at all in Great Britain, because the 10x wagering cap limits bonus wagering to ten times the bonus.

The 2024 William Hill ruling matters for anyone comparing offers: excluded payment methods are a significant condition. That is why our pages on how payment exclusions work treat them as a headline term, not a footnote.

How the advertising codes connect to Gambling Commission licences

The CAP Code gets extra force from the Gambling Commission’s licence conditions and codes of practice. LCCP social responsibility code 5.1.6 requires licensees to follow the UK advertising codes, so an ad that breaks CAP 16 is also a potential breach of licence.

LCCP 5.1.9 adds the Commission’s own rule on incentives: all significant conditions of a marketing incentive must be given transparently and prominently in ads and at the point of sale, with full terms no more than one click away online, and each incentive’s terms must stay available for the whole promotion. The Commission’s 5.1.9 code text (opens in a new tab) also bars misleading actions or omissions under the Digital Markets, Competition and Consumers Act 2024.

So one weak ad can trigger two separate processes: an ASA investigation under the CAP Code and a regulatory question for the Commission. Operators are responsible for their affiliates’ marketing, which is why partner casinos review pages like this before they go live.

How to check a casino bonus ad against CAP 16

You don’t need to memorise the code to spot a problem. Run any bonus ad through these checks:

1. Look for 18+ and a note that terms apply. Their absence is an early warning.
2. Find the qualifying action. If the ad says ‘free’, the deposit or bet needed should sit right beside it.
3. Check for the significant conditions: wagering (no more than 10x the bonus since 19 January 2026), expiry, minimum deposit, eligible games and excluded payment methods.
4. Click through once. The full terms should open from the ad or landing page without hunting through a footer.
5. Look at the people and style. Anyone who looks under 25 gambling, or youth-culture design, points to a breach of 16.3.12 or 16.3.14.
6. Read the message. Claims that gambling fixes money worries, lifts your status or is an escape from problems break rules 16.3.3 to 16.3.6.

Our bonus terms explained guide shows how to read the terms page you reach after that one click, and how to read a significant terms box covers the summary box many casinos now show beside an offer.

What the UK advertising codes don’t cover

CAP 16 is about the advert, not the product. Several things people assume it controls actually sit elsewhere:

• Wagering limits and bonus structure: set by LCCP social responsibility code 5.1.1, which since 19 January 2026 caps wagering at 10x and bans mixed-product promotions.
• Whether a term is fair: decided under consumer law, especially the Consumer Rights Act unfair terms rules, and the Commission’s fair-terms guidance.
• Marketing emails and texts you didn’t ask for: covered by the Commission’s marketing consent rules as well as data protection law.
• Unlicensed operators: the ASA refers them to the Gambling Commission rather than ruling on them as if they were licensed.
• Northern Ireland, the Channel Islands and the Isle of Man: the code itself recommends specialist legal advice for gambling marketing there.
• Industry pledges such as limits on TV ads during live sport: these are voluntary industry codes, not CAP rules.

Why CAP 16 is stricter than most UK ad rules

Most products can be advertised with a light touch: be honest, don’t mislead. Gambling is treated differently because the product carries a risk of harm and because adverts can reach people who are already struggling. CAP’s approach is to block the messages most likely to draw in young or vulnerable people (status, escape, money fixes, youth culture) while still letting licensed operators tell adults what they offer.

For bonus advertising the logic is simple. A promotion is the most persuasive part of a gambling ad, so it is where the most care is needed. Showing the true cost of an offer, such as how much play the wagering demands, is part of treating gambling as paid entertainment rather than a way to make money. The house edge still applies to every spin played with a bonus.
