Weight Loss Clinic Website Design in the UK: Structure, Trust and What You Can Say

A good weight loss clinic website explains your approach, shows who your clinicians are, makes the consultation easy to book and stays within UK advertising law. The key constraint: prescription-only medicines, including weight-loss injections, must not be advertised to the public under CAP Code rule 12.12. Design around the consultation, not the drug.

That one rule shapes almost every page. It affects your homepage, your treatment pages, your ads and the pages those ads link to. This guide sets out what the rule says, how to structure a compliant site, which trust signals to show, and how to track it all responsibly. It is general guidance, not legal advice.

What can a weight loss clinic website say about prescription medicines?

Less than most clinics expect. According to CAP's advice on weight control and prescription-only medicines (dated 29 May 2026), CAP Code rule 12.12 says prescription-only medicines (POMs) and POM treatments may not be advertised to the public.

In non-broadcast media, including online and sponsored ads, almost any reference to a POM is treated as promoting it, whether or not the medicine is named. CAP issued an enforcement notice on prescription-only medicines used for weight management, updated in September 2025, and its advice names semaglutide and Mounjaro as examples. The MHRA is the body to ask about licensing and marketing authorisation.

The ASA has treated the following as promoting a POM, in rulings listed by CAP:

• Brand names, active ingredients and class terms such as GLP-1.
• Colloquial terms such as 'skinny jab', and phrases such as 'weight loss injections' or 'weight loss pen'.
• Images of injection pens or vials, branded or not.
• Prices, discounts or time-limited offers that apply only to a POM, even without naming it.
• A generic 'weight loss treatments' headline where the linked page names a POM or implies one is the likely outcome.

There is a narrow exemption for inner pages of a clinic or pharmacy's own website. CAP says it does not cover the homepage or a landing page that the marketer actively links to. CAP points to separate advice on POM websites for the detailed conditions, which we have not reproduced here, so take your exact wording to CAP Copy Advice before publishing.

What does this mean for ads that lead to your website?

Your website and your ads are judged together. CAP says an ad may offer a consultation for weight loss, but must not suggest that a POM will be the likely outcome, either in the ad or on the page it links to. Several ASA rulings turned on the landing page, not the ad.

Google applies its own limit. Under its Healthcare and medicines policy, UK telemedicine providers certified by LegitScript, and online pharmacies registered with the General Pharmaceutical Council, can advertise with limitations, but they cannot promote prescription drugs in ads and landing pages (Google Ads Healthcare and medicines policy). Our posts on Google Ads healthcare policy for online clinics and Google Ads compliance for UK clinics go into this.

How should a weight loss clinic website be structured?

Build around the patient's real questions: Is this for me? Who will look after me? What happens at the first appointment? Is it safe and regulated? A workable structure:

• Homepage: your approach to medically supervised weight management, the lifestyle and nutrition support you offer, clinician credentials and a clear booking route. No POM names, pens or prices.
• Programme or approach pages: nutrition, activity, behavioural support, monitoring and follow-up, written as a service rather than a product.
• Consultation page: what happens, who you see, how long it takes, what it costs and what you will ask.
• Who it is for: general eligibility and who should speak to their GP first, without implying a particular treatment is the outcome.
• Team and clinical governance: named clinicians, registrations, how care is supervised, complaints and safeguarding.
• FAQs, contact and reviews: answers that do not mention POMs on public pages unless cleared.

Our guides to the condition page template and healthcare website design show how to lay out pages that lead to consultations.

What should the eligibility and consultation flow look like?

Promote the consultation itself. CAP says marketers should promote the consultation, or a medicine that can lawfully be advertised to the public, not a POM. The decision about treatment belongs to a prescriber after assessment.

1. Start with a short enquiry or booking form. Name, contact details, preferred time and a general reason for enquiry.
2. Keep the health questionnaire for after booking. Collect the detailed medical history in a secure, consented step, not in a public form or a URL.
3. Describe the consultation neutrally. 'A clinician will talk through your health, goals and options.' Avoid hinting that an injection is the expected result.
4. Be careful with eligibility checkers. A BMI calculator that funnels everyone to a medicine page risks being read as a path to a POM. CAP says ads must not suggest weight-loss treatments suit people who are not overweight.
5. Confirm what happens next. Reminders, how to prepare, and what to do if they need to cancel.

The ASA has also ruled against short-term pricing and urgent wording such as Black Friday prices for weight-loss medicines, as irresponsible because they push rushed decisions. Leave countdown timers off these pages.

Which trust signals and clinical governance pages do you need?

Weight loss is a sensitive area, so trust has to be visible. Show things a patient can verify rather than adjectives.

• Named clinicians with their role and professional registration number, and a link to the regulator's public register (GMC, NMC or GPhC as appropriate).
• Who prescribes and who supervises. Explain who is responsible for care at each step.
• CQC registration and rating, where it applies. Under Regulation 20A of the Health and Social Care Act 2008 (Regulated Activities) Regulations 2014, providers that have been rated must show the Commission's web address, a link to their latest assessment and the latest rating on their website, with dates (legislation.gov.uk). Whether your service needs CQC registration depends on what you provide, so confirm with CQC.
• GPhC details for pharmacies. If a registered pharmacy is involved, follow the GPhC's guidance on providing pharmacy services at a distance, including online.
• Complaints, safeguarding and data protection pages.
• Genuine reviews, displayed accurately (see showing reviews on your clinic website).

Which claims, results and images are safe on a weight loss site?

CAP's weight control guidance sets out several limits that apply regardless of the medicine question.

• Substantiation: claims for a slimming method need rigorous practical trials on people. Testimonials alone are not enough (rule 13.1).
• Precise amounts: do not claim exact weight loss within a stated period, or loss from specific body parts (rule 13.9).
• No guarantees: do not suggest results are certain or permanent (rule 13.8).
• Under-18s: weight-reduction regimes must not be aimed at them (rule 13.3).
• Body image: avoid shaming language and images that play on insecurity. The ASA has ruled such ads irresponsible.
• Endorsements: health professionals or celebrities must not endorse a medicine (rule 12.18).

Before-and-after photos need particular care. CAP says they are likely to be treated as advertising claims, which POMs may not make, so POM marketers should avoid them. They may be acceptable only if clearly attributed to a non-POM service, and the weight-control and social responsibility rules still apply. See also before-and-after photos, consent and trust.

How do you keep a weight loss clinic website accessible?

Accessibility is a trust issue as well as a legal one. Many visitors will be anxious, on a phone, or using assistive technology. Aim to meet WCAG 2.2 level AA.

• Sufficient colour contrast, especially on buttons and form labels.
• Forms with visible labels, clear error messages and no reliance on colour alone.
• Keyboard-friendly navigation and visible focus states.
• Descriptive alt text, captions for any video and readable type sizes.
• Plain English at a comfortable reading level, with no stigmatising wording about weight.

Our healthcare UX web design service covers accessibility audits, and the accessibility statement shows how we approach it.

How should you set up tracking for a weight loss website?

Measure enquiries and booked consultations, but treat weight, BMI and medical answers as sensitive. Do not pass them to analytics or advertising platforms, and never put them in URLs or page titles.

• Track form submissions, calls and chat starts as separate events.
• Track consultations booked and attended from your booking system.
• Use consent mode and a clear cookie banner (GA4 consent mode for clinics).
• Review third-party scripts regularly (GDPR and patient data in marketing).

On Google, health is a sensitive interest category, so advertiser-curated audiences such as Customer Match and lookalikes are not available for health advertisers (Google Ads personalised advertising policy). Expect remarketing from weight loss pages to be limited.

What this means for your clinic

Weight loss clinic website design in the UK starts with the regulatory limits. Build around your clinicians, your supervision model and your consultation. Keep public pages free of POM names, pens, prices and outcome hints unless CAP Copy Advice has cleared them.

Then add visible trust signals, accessible pages and careful tracking. If you would like a second pair of eyes, see our weight loss clinic marketing work.
