If you are weighing up Wegovy on the NHS vs private supply, the honest headline is this: the NHS route can be far cheaper — often free — but for most people it is either unavailable or comes with a long wait. Private supply costs money every four weeks, but you can usually start within days. This guide sets the two routes side by side on the things that actually decide it: who qualifies, how long you wait, and what you pay.
We have pulled the private figures from our UK provider dataset, checked on 4 July 2026, so the cost comparison uses real prices rather than round-number guesses.
NHS Wegovy is very cheap but hard to access: tight eligibility, specialist-service referral, a time limit of around two years, and waiting lists that can run into months or longer. Private Wegovy is available quickly to a wider range of people and costs roughly £80 to £230 per four weeks depending on dose and provider — an ongoing bill, but with no queue.
Wegovy on the NHS: who can get it and how
Wegovy (semaglutide) is available on the NHS, but only through specialist weight-management services and only for people who meet strict criteria set by NICE (guidance TA875). In practice that usually means a body mass index of at least 35 with a weight-related health condition, though the exact thresholds vary and lower BMI cut-offs can apply for some ethnic groups.
You cannot simply ask your GP for a Wegovy prescription and collect it from a pharmacy. Access runs through a tier-3 or specialist weight-management service, which your GP refers you into. NHS treatment is also time-limited — typically up to around two years — and is delivered alongside a support programme covering diet, activity and behaviour.
The cost, if you qualify, is low. Wegovy on the NHS is dispensed like any other NHS medicine, so in England you pay the standard prescription charge per item (or nothing at all if you are exempt — for example if you hold a valid prescription prepayment certificate or qualify for free prescriptions). In Scotland, Wales and Northern Ireland, prescriptions are free. That is the NHS route's great strength: for the people who get in, it is dramatically cheaper than paying privately.
The catch: eligibility and waiting
The difficulty is getting in. Specialist weight-management services are limited, referral criteria are narrow, and demand has far outstripped capacity since these medicines became popular. Waiting times vary widely by area and can stretch to many months. Some services have paused new referrals at times. If your BMI sits below the specialist threshold, or you do not have a qualifying health condition, the NHS route may not be open to you at all — however much you would benefit.
None of this is a criticism of the NHS; it reflects rationing of a genuinely in-demand treatment. But it does mean that for a large number of people, "wait for the NHS" is not a realistic plan. That is where private supply comes in.
Wegovy private cost: what you actually pay
Buying Wegovy privately means paying per four-week pen through a GPhC or CQC-regulated online pharmacy, with a clinical consultation to confirm it is suitable. There is no prescription charge and no NHS eligibility test in the tier-3 sense; the prescriber assesses you against the licensed criteria (typically BMI 30+, or 27+ with a weight-related condition) and decides.
Price depends heavily on dose. Wegovy is titrated up a five-step ladder — 0.25mg, 0.5mg, 1mg, 1.7mg, then the 2.4mg maintenance dose — and each pen is priced separately, so your bill rises as your dose does. Across our dataset of 24 providers stocking Wegovy, the standard four-weekly starter (0.25mg) price ranges from around £79.97 at the cheapest to £164 at the dearest, while the 2.4mg maintenance pen runs from about £174.99 up to £249.
First-month discount codes push the entry price lower still: the cheapest first-pen deals in our data land near £59.99. Those offers almost always apply to the first order only, so the maintenance-dose price is the number that matters for long-term budgeting. Our sibling guides break this down in detail — see Wegovy prices by dose and what the maintenance dose really costs.
The Weight Clinic is our recommended provider: a GPhC-registered pharmacy with a clinical consultation, monthly video reviews as your dose steps up, and a refund if you are declined. New patients can use code NEWME for £35 off the first order — Wegovy from £80 for the first month on the 0.25mg starter dose.

NHS vs private Wegovy compared
The table below sets the two routes against each other on the factors people actually decide on. Private figures are four-weekly prices from our dataset, checked on 4 July 2026; NHS figures reflect standard prescription rules.
| Factor | NHS Wegovy | Private Wegovy |
|---|---|---|
| Cost per 4 weeks | NHS prescription charge per item (England), or free if exempt / free in Scotland, Wales & NI | ~£80 first month with a code, then ~£175–£230 at maintenance depending on provider |
| Who qualifies | Usually BMI 35+ with a weight-related condition, via specialist service (NICE TA875) | Typically BMI 30+, or 27+ with a weight-related condition; prescriber decides |
| How you access it | GP referral into a tier-3 / specialist weight-management service | Online consultation with a regulated pharmacy |
| Typical wait | Weeks to many months; some services paused at times | Usually days, subject to clinical approval |
| Time limit | Around two years, with a structured support programme | No fixed limit; you continue while it is appropriate and you keep paying |

Which route is right for you?
There is no single answer, but a few patterns hold. If your BMI and health profile clearly meet the specialist threshold and you can tolerate a wait, the NHS route is the most cost-effective by a wide margin — it is worth asking your GP about a referral. If you do not qualify for specialist services, or the local wait is impractical, private supply is the realistic option, and the question becomes which provider offers the best value across the full dose ladder rather than just the headline first-month deal.
Some people also start privately to begin treatment quickly, while a specialist referral works its way through the system. That is a decision for you and a prescriber, not something to rush into on price alone — Wegovy is a prescription-only medicine with real side effects, and continuing or switching supply should be a clinical conversation, not a checkout one.
Whichever way you lean, it pays to compare. Our Wegovy price table ranks every provider in our dataset by price, and our guide to the cheapest Wegovy in the UK shows where the genuine value sits once first-order discounts wear off.
If you decide the private route suits you, The Weight Clinic is our pick: a GPhC-registered pharmacy with monthly video reviews as your dose steps up, next-day delivery with needles included, and a refund if you are declined. New patients get NEWME for £35 off the first order.

Frequently asked questions
Is Wegovy free on the NHS?
Broadly, yes, if you qualify. Wegovy on the NHS is dispensed as an ordinary NHS medicine, so in England you pay only the standard prescription charge per item — or nothing if you are exempt. Prescriptions are free in Scotland, Wales and Northern Ireland. The barrier is not cost but access: you have to meet the specialist-service criteria and be referred in.
Why can't I just ask my GP for Wegovy?
NHS Wegovy is only prescribed through specialist (tier-3) weight-management services, not directly by a GP for pharmacy collection. Your GP's role is to assess you and refer you into that service if you meet the criteria under NICE guidance TA875. If you do not qualify, or the local service is oversubscribed, a private consultation with a regulated pharmacy is the alternative.
How much cheaper is the NHS than paying privately?
Considerably. Privately, Wegovy costs roughly £80 for a discounted first month and around £175 to £230 per four weeks at the 2.4mg maintenance dose, depending on provider. On the NHS you pay at most the standard prescription charge per item, and often nothing. Over a year the difference runs to well over a thousand pounds — the trade-off is eligibility and waiting.
Can I switch from private to NHS Wegovy later?
Potentially, if you become eligible for a specialist service and are referred in. Some people start privately to begin treatment quickly, then move to NHS supply if a referral comes through. This should be managed with a prescriber so your dose and support continue safely — it is a clinical decision, not just a cost one.
Does private Wegovy have looser eligibility than the NHS?
Usually, yes. Private prescribers work to the licensed criteria — typically a BMI of 30 or more, or 27 or more with a weight-related condition — which is broader than the specialist-service thresholds the NHS uses to ration treatment. But "broader" is not "guaranteed": a prescriber still assesses you and can decline. Reputable providers refund the consultation fee if you are not approved.
