Our assessments cannot be purchased, and our rankings reflect our methodology — not our revenue.
What we are
WeightLossComparison is an independent editorial platform. Our editorial decisions are made independently of commercial relationships. Where we have affiliate relationships with providers, we disclose them.
How we work
We source price and availability data directly from providers, update it on a defined schedule, and publish our sources. We do not accept payment for editorial placement. Affiliate relationships do not influence our editorial assessments.
Our methodologyOur commercial model
We generate revenue through affiliate relationships with some providers we review. These are disclosed on every relevant page. A provider cannot pay to improve their assessment.
Affiliate disclosureWeight-loss treatment choices are not straightforward. NHS access can be limited, private providers differ in how they assess and support patients, and prices vary more than they should. We keep the research current and the comparisons plain.

Treatment landscape
Licensed weight loss treatments in the UK
There are two primary routes for licensed weight loss treatment in the UK: injectable treatments and tablet treatments. Access is NHS or private, and eligibility varies by treatment and individual circumstances.
Injectable treatments
Tablet treatments
Across 81 providers with a public Mounjaro 2.5mg starter price checked on 23 June 2026, the listed monthly price ranges from £109.95 to £229.00 before delivery, offers and follow-up terms are taken into account.

How UK providers differ
Price is the easiest thing to compare. The harder differences are who reviews you, how the consultation works, what support is available, and what happens if treatment changes.

Information is presented to help visitors compare treatments, understand affiliate links and see what still needs confirming with the provider.
Check before deciding
Confirm suitability, stock, current terms, delivery, support, discount-code eligibility and the final payable amount directly with the provider.
Choose the next page
Move from this page into the most specific comparison page once you know whether your question is about provider fit, cost, tablets, injections or a particular brand.
What should I compare before choosing a weight-loss provider?
Compare the treatment type, consultation checks, support, delivery terms, listed fees, offer context and whether the provider explains final confirmation clearly.
Are injections and tablets directly interchangeable?
No. They can differ by medicine, format, evidence, licensing, access and provider assessment. Use a treatment-specific comparison before deciding what to inspect next.
Does WeightLossComparison recommend a provider?
No. The site helps structure comparison research. Suitability, stock and final terms must be confirmed by a regulated provider.
Treatment update
Oral Wegovy now has its own treatment guide
Use it for the approval date, the route differences and the provider context before you compare tablets and injections side by side.
