Influencer Marketing Regulations in the UK and EU

Introduction

The disclosure rules for influencer marketing have existed for years. What changed in 2026 is that they finally have teeth. UK regulators can now reach for fines measured as a share of a company's global turnover, which turns disclosure from a box-ticking nicety into a real financial risk. Here is where the UK plus EU rules stand now, plus what brands actually need to do. One caveat up front: this is general information, not legal advice, plus you should confirm specifics with a qualified professional.

The UK rules

Two bodies regulate UK influencer marketing. The ASA is the self-regulatory watchdog that enforces the CAP Code plus publishes rulings, plus while it has no direct legal power, it refers serious cases onward. The CMA enforces consumer protection law plus can take real legal action.

The core rule is simple: advertising must be obviously identifiable as advertising. If a brand provides payment or control, the content must be clearly labelled with a term like Ad or Advertisement, upfront, using platform disclosure tools. Vaguer tags like gifted, hashtag-collab or PR trip are generally not enough on their own, plus even resharing an ad needs its own disclosure. Both the brand plus the creator are on the hook, plus rulings can name both. The big shift is enforcement: under the Digital Markets, Competition and Consumers Act, in force from 2025, the CMA can reportedly fine up to 10 percent of global annual turnover for serious or repeated breaches. That is the teeth.

The EU rules

The EU works differently, through harmonized consumer protection law applied with country-specific enforcement. The Unfair Commercial Practices Directive bans misleading plus covert advertising, plus the Digital Services Act layers on transparency obligations for platforms plus advertisers. The principle echoes the UK: hidden marketing is the thing regulators are hunting.

It is also a moving target. A proposed Digital Fairness Act, expected around late 2026, may take direct aim at influencer marketing, with the Commission flagging concerns about undisclosed ads, the promotion of harmful products plus unrealistic beauty standards. Enforcement varies sharply by country, with some such as France particularly strict, including the possibility of serious penalties. So a campaign that clears the rules in one member state may not in another, which makes local checks essential.

What brands must do

Build disclosure in, do not bolt it on. Put clear labelling requirements into every creator brief plus contract, specify acceptable labels rather than leaving it to the creator's judgment plus require platform disclosure tools on each post, not a buried line in a bio.

Then manage the risk you cannot delegate. Since both parties are liable, partner with creators who already disclose properly plus behave professionally, treat regulated categories like finance, gambling plus anything aimed at children with extra care plus keep records of your compliance steps. Above all, because the rules keep shifting plus the fines now bite, get qualified legal advice for your specific markets rather than relying on a general guide like this one.
