The UK Wegovy price index: every dose tracked

If you want the Wegovy price index UK shoppers actually need, here it is: the lowest ongoing price at every semaglutide dose, checked on 17 July 2026 across the GPhC-registered pharmacies and CQC-regulated clinics we track. The headline number is a £105.03 spread — Wegovy 0.25 mg runs from £89 to £185 for four weeks, for the identical pen.

Wegovy is a prescription-only medicine. A prescriber decides whether it is suitable for you; this page is a price index, not medical advice. With that stated, let's look at the numbers.

The Wegovy price index UK: cheapest by dose

Wegovy titrates from 0.25 mg up to a 2.4 mg maintenance dose. Prices are quoted per four weeks. The table below shows the lowest ongoing figure we recorded at each rung, plus where our recommended provider, The Weight Clinic, sits.

The clustering matters: at the starter dose more than a dozen pharmacies sit within a fiver of the low, between roughly £88 and £92. Above that band, the price you pay depends heavily on the provider tier rather than the medicine.

The full ongoing price ladder

Here is the lower end of the starter-dose board so you can see how tightly the cheapest names bunch — and where the mid-market and premium services land.

Note how a first-month promo can flip the ranking for month one. MedExpress and ZAVA both drop to £59.99 for a new patient's starter box — cheaper than any standing ongoing price. But those promos apply to the 0.25 mg dose only, so treat them as a one-off, not a running rate.

Our recommended provider, The Weight Clinic, isn't the cheapest sticker price on the board, but it pairs a £35-off first order (code NEWME, taking the starter month to £80), monthly video reviews and a refund if the prescriber declines you. For a first-time semaglutide patient, that structure often matters more than the last few pounds.

Why the £105 spread exists

It is the same licensed pen from the same manufacturer. The gap comes from what wraps around it:

Service model

CQC-regulated clinics bundling coaching, app tracking and clinician reviews sit at the top of the ladder. Barebones dispensing pharmacies sit at the bottom. Neither is "wrong" — but if you don't need the hand-holding, you're paying for it.

Promo timing

First-month discounts distort the picture. A £59.99 starter month looks unbeatable until you reach maintenance dose at full ongoing price. Always model your likely total over six months, not month one.

Stock and code churn

Prices and discount codes move between our monthly checks. The figures here are what we logged on 17 July 2026. Confirm the live price on the provider's own site before ordering — always.

Wegovy vs Mounjaro on price

On sticker price, Wegovy undercuts Mounjaro at the comparable starter rung — £89 versus £131. But that is a price comparison only. Trial evidence tends to favour tirzepatide for average weight loss: SURMOUNT-1 recorded around 21% at higher tirzepatide doses, versus roughly 15% for semaglutide 2.4 mg in STEP 1, and SURMOUNT-5 put the head-to-head at about 20% vs 14%. Lower price does not automatically mean better value per kilogram lost.

We run that maths in Mounjaro vs Wegovy cost per percentage point, and track the tirzepatide side in the UK Mounjaro price index. For the full market view, see our July 2026 GLP-1 price index report, and the live board on our homepage price table.

What to check before you order

• Your likely maintenance dose. Most people settle at 1.7 mg or 2.4 mg. Price that rung, not the starter.
• Total over six months, including any first-month promo — not the headline.
• Regulation. Every provider we list is GPhC-registered or CQC-regulated. Never buy from unregulated sellers or "compounded" semaglutide; if it isn't a licensed pen from a registered UK pharmacy, walk away.
• Side effects. Common ones include nausea, diarrhoea and constipation. Report any suspected reaction via the MHRA Yellow Card scheme.
