The CAP Code and Healthcare Marketing
The UK Code of Non-broadcast Advertising and Direct & Promotional Marketing — universally referred to as the CAP Code — is the primary rulebook for non-broadcast advertising in the United Kingdom. For healthcare marketing teams, the CAP Code is one of the most frequently relevant regulatory frameworks, applying to virtually every piece of marketing content produced: clinic websites, social media channels, email newsletters, patient leaflets, and paid digital advertising.
The CAP Code is administered by the Committee of Advertising Practice (CAP), a self-regulatory body representing advertisers, agencies, and media owners. Enforcement is carried out by the Advertising Standards Authority (ASA). While the CAP Code is technically a self-regulatory instrument, non-compliance has significant practical consequences: upheld ASA rulings require content removal, are publicly published, and can trigger referral to statutory regulators including MHRA, CQC, and Trading Standards.
For healthcare organisations, three areas of the CAP Code are particularly critical: the substantiation requirements for health claims (Sections 3 and 12), the specific rules for cosmetic interventions (Section 15), and the testimonial and endorsement standards that govern how patient experiences can be used in advertising.

CAP Code: Core Principles for Healthcare Advertisers
Substantiation (Rules 3.1 and 3.7)
All marketing communications must be honest and capable of substantiation. Healthcare advertisers must hold evidence to support every factual claim before publication — not after a complaint is received. The standard of evidence required corresponds to the nature and seriousness of the claim. Efficacy claims require clinical evidence; safety claims require documented risk data.
Health Claims and Section 12
Section 12 of the CAP Code applies to medicines, medical devices, treatments, and health-related products. Claims about prevention, treatment, or cure of medical conditions require the level of evidence expected by the relevant scientific and medical consensus. Claims that a product or service can treat a named medical condition typically require clinical trial evidence.
Cosmetic Interventions (Section 15)
Section 15 imposes specific obligations on advertising for surgical and non-surgical cosmetic procedures. Advertising must not trivialise the decision to have a procedure, must not target under-18s, and must not feature promotions (discounts, limited-time offers) in a way that encourages impulsive decisions. Advertising directed at people with body image concerns must be handled with particular care.
Testimonials and Endorsements (Rule 3.45)
Testimonials used in advertising must be genuine and must reflect the experience of the person providing them. In healthcare, testimonials that include clinical outcome claims must be supported by robust evidence. Testimonials cannot imply that results are typical unless they are. Paid endorsements or incentivised reviews must be clearly disclosed.
Pricing and Promotions (Section 8)
Healthcare pricing advertising must present the total cost of treatment clearly. Where optional extras, consultation fees, or aftercare costs are not included in a headline price, this must be made clear. Promotional offers (discounts, referral incentives) must clearly state the full terms and must not create artificial urgency.
CAP Code Compliance in Practice
Effective CAP Code compliance in healthcare requires more than a checklist review. Healthcare marketing teams need to understand which CAP Code rules apply to their specific sector, channel, and audience — and apply the appropriate evidence standard to every claim before publication.
LearnedCare Sentinel maps submitted content to the relevant CAP Code sections based on your context settings. The platform identifies specific claims that require substantiation review, sections that may fall under Section 12 or Section 15, and testimonial language that may need to be qualified. Findings reference the relevant CAP Code rule number and provide a plain-English explanation of the risk.
The governance workflow creates a documented approval chain — every review decision is recorded with the reviewer's identity and rationale. This audit trail supports your ability to demonstrate that content was reviewed and approved against CAP Code requirements, which is increasingly important in ASA investigations and CQC inspections.
