The rule library

Graded against the rules regulators actually enforce

An enforcement notice tells a whole sector, in advance and in writing, what will be treated as a breach — so from its date, 'we didn't know' is gone. Every flag CheckFirst raises maps to a rule like the one on the right: named, sourced, dated.

Most of these are quick fixes — and the free checker shows you the exact words to change. Want a person to check your whole estate instead? That's the Snapshot. Every ruling we track is on the rulings page.

From the rulings
CAP, with the MHRA and the GPhC, has told advertisers that promoting a prescription-only weight-loss medicine — Wegovy, Mounjaro, Ozempic — by name in an ad for weight-loss products or services is “almost certainly a breach of the rules”.

CAP Enforcement Notice: Advertising of prescription-only medicines used for weight management, published jointly with the MHRA and the GPhC — current version 23 September 2025 (first in force 11 April 2025).

CheckFirst flags exactly this (MHRA-001) before it costs you the ad account — not after the complaint lands.

POMs must not be advertised to the public

Prescription-only medicines must not be advertised to the public (UK Human Medicines Regulations 2012). Naming a POM in promotional consumer content is a red flag — including named GLP-1 weight-loss medicines and named TRT medicines. The CAP Enforcement Notice on prescription-only medicines used for weight management (published jointly with the MHRA and the GPhC; first in force 11 April 2025, current version 23 September 2025) also treats injection-pen imagery and 'prescribed on the NHS' references as indirect POM advertising. Maintain per-vertical POM name lists.

How it works

Three steps. No upload, no account, no waiting room.

  2. 02We run the library. The same rule packs we run on ourselves: CAP Code, MHRA, the EU AI Act, Google Ads and per-platform AI labels.
  3. 03Get your grade — and the fixes. An A+ to F compliance grade, every risky phrase highlighted in your own copy, and a one-click rewrite.

You come away with a grade, the exact phrases to change, and the named, dated rule behind every flag.

Compliance Certificate

Prove it passed — with a public certificate

When an ad comes back clean, CheckFirst can issue a Compliance Certificate: a public, tamper-evident record of exactly what was checked, against which rule-set, on which date. Anyone can verify it — no login.
