Most owners think advertising regulation works like a smoke alarm. Someone complains, the regulator turns up, you find out about it. That has not been how it works for a while, and the numbers now make it hard to ignore.
The Advertising Standards Authority says its Active Ad Monitoring system processed more than 60 million ads in 2025, supporting over 30 regulatory projects. Nobody had to complain about any of them for the system to take a look.
What the system actually does
The ASA built Active Ad Monitoring in-house. It captures advertising from social media platforms, search engines, websites and influencer content, then uses AI models to flag ads that look likely to breach the rules. ASA staff then review what the system surfaces and decide whether anything happens.
That last part matters, and the ASA is blunt about it. In its own words, it uses AI to support the work of ASA experts, not to replace them. No machine bans your ad. A person still makes the call. What the machine changed is how many ads reach that person’s desk in the first place.
The trajectory is the real story. In a July 2023 blog post, the ASA said the system was processing more than 100,000 ads a month. Annualise that and you get roughly 1.2 million a year. The 2025 figure is more than 60 million. Both numbers are the ASA’s own, and both are stated as minimums, so treat the multiple as a direction of travel rather than a precise ratio. The direction is not subtle.
Why this matters if you run a business
The complaint used to be the bottleneck. A local business running a handful of paid social ads could reasonably assume nobody was watching, because in practice nobody was. Proactive capture removes that assumption.
Be honest about the scale of the risk, though. The ASA listed its 2025 monitoring projects as environmental claims, gambling, alcohol advertising, prescription-only weight-loss medicines, and cosmetic surgery services based outside the UK. If you fit windows in Wakefield, you are not the priority.
But environmental claims are on that list. “Eco-friendly”, “sustainable” and “carbon neutral” sit on thousands of ordinary UK business websites, written by people who meant well and who hold no evidence for any of it. That is where a national enforcement programme and an ordinary trading business overlap.
The claims that actually catch businesses out
| What owners expect to be a problem | What actually gets flagged |
|---|---|
| Bold, obviously exaggerated slogans | Specific factual claims with no evidence file behind them |
| Competitor comparisons | Green wording like “eco-friendly” used loosely |
| Images and design | Prices that do not include everything the customer must pay |
| The offer being too generous | Promotions the business could not actually honour |
Two recent ASA rulings show the pattern. One established that “subject to availability” is not a shield for a promotion a business cannot honour. Another found that the contact details on your advert are themselves an advertising claim. Neither business was doing anything exotic. Both were doing what looked to them like normal marketing.
What to do this week
- List every factual claim in your live ads. Not the adjectives, the facts. Numbers, timescales, qualifications, accreditations, guarantees.
- Put one evidence file behind them. One folder, one document per claim. If you cannot fill it, change the claim.
- Rewrite loose green claims. “Eco-friendly” says nothing and is on a named monitoring list. “Our vans went electric in 2025” says something and is provable.
- Show the total price. Every compulsory fee, in the first price the customer sees.
- Check your promotions can be honoured. Stock, staffing, capacity, dates.
Worth knowing: the ASA runs a free Copy Advice service for advertisers who want a claim checked before it goes out. Most businesses have never heard of it, and it costs nothing to use.
The takeaway
Spending more on ads that carry claims you cannot evidence only buys a bigger audience for the problem. UK advertisers put £46.7 billion into advertising last year, and where that money actually went shows how crowded the field already is. Getting your claims right is not compliance admin to be done later. It is the structural bit that has to hold before more spend makes any sense.
Open your live ads today. Read every sentence that states a fact. Ask what you would send the ASA if they asked you tomorrow. If the answer is nothing, you have found this week’s job.
