A price index, not a pharmacy.
GLP Prices does one job: it tells you what GLP-1 weight-loss medicines actually cost in the UK, across every regulated online provider we can verify, on a stated date. That's the whole product.
Why this site exists
At any given dose, every UK provider dispenses the identical manufacturer product. Yet at our 24 August 2026 check the gap between the cheapest and dearest listing ran from £70 to £90 per 4-week supply — up to £1,170 a year for choosing the wrong checkout. That gap is invisible unless someone lines the numbers up. We line the numbers up.
What we track
Three medicines — Mounjaro (tirzepatide), Wegovy (semaglutide) and the oral Wegovy pill — across 24 online providers, every dose on each ladder. For each provider we record the published ongoing price per 4 weeks, any first-order promotional price and its code, delivery terms, and what support is bundled in. Every listed provider is a GPhC-registered pharmacy or CQC-regulated clinic; we do not track, link or price unregulated sellers or "compounded" products, ever.
The rules of the board
- Published tariffs only. Every figure comes from the provider's own public pricing page. We never estimate and never extrapolate.
- Sorted by arithmetic. Tables rank ascending by ongoing price. No provider can pay for position.
- One flagged exception. Our recommended provider, The Weight Clinic, is pinned to the top of each table with a ★ — with its real prices and its real distance from the board low printed in the row. Pinned, labelled, honest.
- Promos quoted separately. First-month codes get their own column and never contaminate the ongoing figure.
- Dated checks. The current board was re-checked in full on 24 August 2026. If a number is stale, tell us and we'll re-check and re-date it.
Why The Weight Clinic is our pick
Not because it's the absolute cheapest — the board shows it sixth of 24 on ongoing Mounjaro 2.5 mg price, £14.01 above the low. It's our pick because of what sits behind its number: a monthly video review with a clinician rather than a questionnaire, needles included, next-day delivery, a refund if the prescriber declines you, and one of the three cheapest first months on the Mounjaro index at £125.00 with code NEWME. On price-to-service, that's the strongest line we track.
What we are not
We are not a pharmacy, a clinic or a prescriber, and nothing here is medical advice. Mounjaro and Wegovy are prescription-only medicines with real side effects; whether they're appropriate for you is a conversation for a prescriber, your GP or your pharmacist — not a comparison table. Suspected side effects should be reported via the MHRA Yellow Card scheme.
