Getting weight loss injections on the NHS: the reality in 2025–26

The biggest myth: 'My BMI is over 30, so I should qualify'

This is the question our prescribers hear almost every week, and the short answer is: BMI alone has never been enough. The NICE criteria for tirzepatide on the NHS require adults to have a BMI of 40 or above alongside four or more of five specified conditions, high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, or type 2 diabetes. That's the threshold active since June 2025 for the first cohort. A second cohort (BMI 35–39.9 with four or more of those conditions) opened in late June 2026. Lower BMI thresholds apply for people from South Asian, Chinese, Middle Eastern, Black African or African-Caribbean backgrounds, typically 2.5 kg/m² lower throughout.

Wegovy on the NHS operates under different guidance. NICE's recommendation for semaglutide (TA875) limits use to a maximum of two years and requires access through a specialist weight management service with multidisciplinary support. Waiting lists for those services are long in most of England. If you want the full detail on who can get weight loss injections on the NHS, the qualifying conditions are set out there clearly.

The point is this: a BMI of 30 to 39 with one or two conditions (which is where many people asking this question sit) doesn't currently open an NHS door to either medicine. If you're trying to understand how weight loss injections work on the NHS, including what the rollout phases mean for future eligibility, that page sets out the picture in full. That may change as the rollout phases progress toward 2027, but right now the gap between 'licensed' and 'NHS-funded' is wide.

How NHS prescribing actually works now, and why it's postcode-dependent

From 1 April 2026, GP practices in England can prescribe tirzepatide under the new QOF contract arrangements. That sounds like good news, and in principle it is. In practice, participation is optional, so whether your surgery offers it depends entirely on the practice. Some CCG areas have moved quickly; others haven't started. Every NHS patient who receives a weight loss injection also has to take part in a 'wrap-around' programme of dietary and activity support, meeting the BMI and condition criteria is necessary but not sufficient.

Scotland, Wales and Northern Ireland have separate arrangements, and the thresholds and timelines differ. If you're outside England, NHS England's guidance on weight management injections covers the England picture; for Scotland, NHS Inform has its own summary. The honest framing: even for people who technically meet the criteria, the NHS route currently involves a conversation with your GP, confirmation that your practice is participating, and then enrolment in a support programme before any prescription is issued.

Referral routes for Wegovy differ again. If you want to understand how referral for weight loss injections works, that page covers both NHS and private paths in detail.

What the private prescription route looks like in practice

For people who don't meet NHS thresholds, or who do qualify but can't face an open-ended wait, a private prescription through a GPhC-registered online pharmacy is the legal alternative. The licensed eligibility for private prescribing follows the SmPC: adults with a BMI of 30 or above, or 27 or above with at least one weight-related condition such as hypertension, high cholesterol, prediabetes or obstructive sleep apnoea.

At nume, the process runs in sequence: free consultation form, same-day review by a named GPhC-registered Independent Prescriber (a clinician reads your answers, not software), photo-ID verification, live weight confirmation on video, and (once approved as clinically suitable) same-day dispatch on orders placed before 12pm. The pen arrives with a DPD tracking notification, in plain unbranded packaging, the next working day. One transparent price covers the consultation, prescription, treatment and delivery. No subscription, no auto-renewal; every repeat order is reviewed again before anything is sent.

If cost is part of the decision, the weight loss treatments page shows current pricing. It's worth reading alongside the broader picture of where to buy weight loss injections safely, because the counterfeit market for these pens is real and the MHRA has warned publicly about it.

What to do if you're not sure which route applies to you

Start with your GP. If your BMI and comorbidities put you anywhere near the current NHS thresholds, a conversation with your surgery costs nothing and establishes whether your practice is participating. Ask specifically whether they are now prescribing tirzepatide under the 2026/27 contract, and whether you'd be referred to a specialist service for Wegovy. You need that information before you can make a sensible comparison.

If the NHS route isn't open to you (or the wait is prohibitive) a regulated private service is the next logical step. Getting approved for weight loss injections privately involves clinical assessment either way; the difference is the timeline and the funding. You can read more about how weight loss injections work before deciding anything. When you're ready, check your eligibility with our prescribers, the consultation is free and there's no obligation to proceed.
