How to Qualify for Wegovy on the NHS: What the Criteria Actually Mean for You

The decision you're actually making: NHS route, private route, or both?

When people search for how to qualify for Wegovy on the NHS, they're usually weighing one of three situations: they want to know whether they meet the criteria before approaching their GP; they've already been told they don't qualify and they want to understand why; or they're deciding whether to wait or explore a private alternative. This page addresses all three.

The NHS route to Wegovy is governed by NICE technology appraisal TA875, published in March 2023. NICE recommends semaglutide (Wegovy) only within specialist weight management services (tier 3 and above) and only alongside a full multidisciplinary programme of dietary support, physical activity guidance and psychological input. That distinction matters. Your GP can refer you, but they cannot prescribe Wegovy directly under the current NHS framework for this indication.

For people who meet the criteria, this is a genuinely good pathway. For people who don't, or who face a long wait, the private route through a regulated pharmacy is a lawful alternative. Understanding both helps you make a decision based on your own circumstances rather than assumptions.

Who the NHS criteria say should qualify, and where the thresholds come from

The NICE criteria for semaglutide on the NHS set a BMI floor of 35 kg/m², combined with at least one weight-related health condition. The conditions that count include type 2 diabetes, high blood pressure, dyslipidaemia, obstructive sleep apnoea and cardiovascular disease, though the specialist team considers the full clinical picture. For people from South Asian, Chinese, Middle Eastern, Black African or African-Caribbean backgrounds, the threshold is reduced by 2.5 kg/m², so 32.5 kg/m² rather than 35.

There is also an effectiveness checkpoint. If you have not lost at least 5% of your starting body weight after six months on the maintenance dose, NICE guidance says continuing treatment should be reviewed. The recommendation covers a maximum of two years of treatment, after which the pathway ends, and the specialist team considers next steps with you.

A question our prescribers hear most weeks is whether a BMI just above 30 qualifies. The honest answer for the NHS route is no, not under TA875's current thresholds, which are higher than the licensed eligibility for private treatment. You can check where you sit using the NHS BMI calculator, though the number is always one piece of a wider clinical conversation.

What typically happens if you don't meet the NHS threshold (or face a long wait

A large number of adults in the UK hold a BMI between 27 and 34.9 with a weight-related condition) within the licensed range for semaglutide, but below the NHS specialist service threshold. Others meet the criteria on paper but find that referral waiting times stretch to many months, or that their local service has not yet expanded capacity. Both situations are common.

For those people, a regulated private pharmacy offers a lawful alternative. The licensed eligibility for private Wegovy is broader: a BMI of 30 or above, or 27 or above with at least one weight-related condition. Every prescription still requires a clinical assessment by a qualified prescriber. If you want to understand that route alongside the NHS one, this page on how to get Wegovy in the UK walks through the practical steps, and our NHS Wegovy overview covers the referral process in more detail if you want to pursue that path first.

It is also worth being clear about cost. Private treatment carries a fee that varies by dose and provider. Understanding what Wegovy costs privately (and what is included in a quoted price) helps you compare options fairly. Prescription, clinical review, delivery and aftercare are not always bundled together, so headline prices are not always the full picture. If you are based in the capital, our guide to buying Wegovy in London sets out how the private process works locally and what to expect from a regulated provider there.

How to take the next step, whichever route suits your situation

If the NHS route looks right, begin with your GP. Explain that you are interested in the specialist weight management pathway and ask about local referral options. Bring your BMI, your relevant health conditions and any medication history, your GP assesses whether a referral is appropriate, and the specialist service makes the prescribing decision from there. If you are in Scotland, Wales or Northern Ireland, the specific thresholds and service structures differ from the NHS England framework described here; NHS England's weight management injections guidance covers the England position in full.

If the private route is what you're considering, the process is different. There is no referral, no waiting list and no requirement for a specialist service. Instead, a GPhC-registered independent prescriber reviews your consultation directly (your health history, current medications and weight) and decides whether treatment is clinically appropriate. Some patients also ask whether financial support is available, and our page on how to get Wegovy for free explains the schemes and circumstances where costs may be covered or reduced. You can read more about getting started with Wegovy for weight loss, or explore all the treatment options we offer if you want to compare before committing to anything.

Whichever path you take, a prescriber (not a website, not a checklist) makes the final call. That is how it should be for a prescription medicine. When you are ready to see whether private treatment is appropriate for you, check your eligibility with a free consultation.
