How to Get Wegovy
on the NHS

A step-by-step guide to the referral process, NICE eligibility criteria, Tier 3 weight management services, waiting times and what to expect at each stage.

Key points

  • NICE approval: Wegovy is recommended for NHS use under technology appraisal TA875
  • Not from your GP directly: Wegovy must be initiated through a specialist weight management service (Tier 3 or equivalent)
  • BMI thresholds: BMI ≥35, or BMI ≥30 with at least one weight-related comorbidity
  • Adjusted thresholds: BMI lowered by 2.5 kg/m² for certain ethnic backgrounds
  • Waiting times: Vary from weeks to over 12 months depending on your area
  • Alternative: Private prescriptions are available if you do not qualify or cannot wait

Can you get Wegovy on the NHS?

Yes. Wegovy (semaglutide 2.4 mg) is available on the NHS for chronic weight management. NICE published its technology appraisal guidance (TA875) recommending semaglutide for use within NHS specialist weight management services, subject to specific clinical criteria.

However, it is important to understand that Wegovy is not available as a straightforward GP prescription for weight loss. The NHS pathway requires referral to a specialist service and meeting defined eligibility criteria. This guide walks you through every step of the process.

Step-by-step: how to get Wegovy on the NHS

1 Book a GP appointment

The process begins with your GP. Book a standard appointment and explain that you would like to discuss your weight and whether you might be eligible for Wegovy through NHS weight management services. Your GP will assess your general health, calculate your BMI and discuss your weight history.

It is helpful to come prepared with information about any previous weight loss attempts, relevant medical conditions (such as type 2 diabetes, hypertension, sleep apnoea or cardiovascular disease) and any family history of obesity-related illness.

2 Meet the NICE eligibility criteria

To qualify for Wegovy on the NHS, you must meet all of the following criteria set out in NICE TA875:

  • BMI of 35 or above, or BMI of 30 to 34.9 with at least one weight-related comorbidity such as type 2 diabetes, hypertension, dyslipidaemia, obstructive sleep apnoea, or cardiovascular disease
  • Willingness to participate in a structured behavioural intervention programme alongside medication
  • Management within a specialist weight management service (Tier 3 or equivalent)

For people from South Asian, Chinese, other Asian, Middle Eastern, Black African or Black Caribbean ethnic backgrounds, the BMI thresholds are adjusted downwards by 2.5 kg/m², reflecting the increased metabolic risk at lower BMI in these populations.

3 GP referral to Tier 3 services

If your GP agrees that you meet the criteria, they will refer you to a Tier 3 specialist weight management service. These are multidisciplinary teams typically based in hospital settings or community health centres that include consultants, dietitians, psychologists and specialist nurses.

The referral pathway varies by Integrated Care Board (ICB). Some areas have well-established Tier 3 services with relatively short waits, while others have limited capacity. Your GP can tell you which local service accepts referrals and provide an estimated waiting time.

4 Tier 3 assessment and programme enrolment

Once your referral is accepted, you will be invited for an initial assessment with the specialist team. This typically involves:

  • A detailed medical history and physical examination
  • Blood tests (including HbA1c, liver function, kidney function, thyroid function and lipid profile)
  • Assessment of eating behaviours and psychological factors
  • Discussion of previous weight management attempts
  • Setting realistic weight loss goals

You will be enrolled in a structured behavioural programme that includes dietary guidance, physical activity recommendations and psychological support. This programme runs alongside any medication prescribed.

5 Wegovy prescription and dose escalation

If the specialist team determines that Wegovy is appropriate for you, they will initiate the prescription. Treatment follows the standard 16-week dose-escalation schedule:

  1. Weeks 1–4: 0.25 mg once weekly
  2. Weeks 5–8: 0.5 mg once weekly
  3. Weeks 9–12: 1 mg once weekly
  4. Weeks 13–16: 1.7 mg once weekly
  5. Week 17 onwards: 2.4 mg once weekly (maintenance dose)

You will receive training on how to use the pre-filled injection pen, injection site rotation and safe storage of the medication.

6 Ongoing monitoring and review

NICE requires that treatment with Wegovy is reviewed regularly. After 6 months on the maintenance dose, the clinical team will assess whether you have achieved at least 5 per cent weight loss. If this threshold has not been met, the team will discuss whether to continue or discontinue treatment.

Ongoing monitoring typically includes regular weight checks, blood tests and assessment of side effects. Some Tier 3 services transfer ongoing prescribing to your GP through a shared care arrangement once you are established on the maintenance dose.

Understanding NHS weight management tiers

The NHS uses a tiered system for weight management services. Understanding this structure helps explain why Wegovy requires a Tier 3 referral rather than a simple GP prescription.

Tier Service What it includes
Tier 1 Universal prevention Public health campaigns, NHS Choices information, community initiatives
Tier 2 Lifestyle interventions Structured weight management programmes (e.g., NHS Digital Weight Management Programme), group sessions, dietary advice
Tier 3 Specialist multidisciplinary Hospital or community-based specialist teams: consultant-led, dietitian, psychologist, specialist nurse. Pharmacotherapy including Wegovy and Mounjaro
Tier 4 Bariatric surgery Surgical interventions (gastric sleeve, gastric bypass) for patients who meet additional criteria

Why Tier 3? NICE requires that Wegovy is prescribed within a specialist service to ensure proper clinical oversight, structured behavioural support and regular monitoring. This is not simply a bureaucratic hurdle — the evidence shows that combining medication with behavioural support produces better long-term outcomes.

Waiting times: what to expect

One of the most common frustrations with the NHS pathway for Wegovy is the variation in waiting times for Tier 3 services across England, Scotland, Wales and Northern Ireland.

Typical waiting times by region

Waiting times vary enormously depending on your location and the capacity of local services:

Your GP or the Tier 3 service itself can usually provide an estimated waiting time for your area. Some ICBs have introduced additional capacity or digital pathways to reduce waiting times in response to high demand for GLP-1 medications.

Tip: If the waiting time in your area is excessively long, ask your GP whether there are any alternative Tier 3 services accepting out-of-area referrals. Some ICBs have established cross-boundary agreements to manage demand.

What if you do not qualify for NHS Wegovy?

If you do not meet the NICE criteria, or if the waiting time is too long, there are other options to consider:

Private prescription

Wegovy is available through private weight loss clinics in the UK. Costs range from approximately £180 to £300 per month depending on the provider and dose. Private clinics can often start treatment within days rather than months. Ensure any provider you use employs GMC-registered prescribers and GPhC-registered pharmacies.

Alternative NHS medications

If Wegovy is not available or appropriate, your clinician may consider other options:

NICE TA875: what the guidance actually says

NICE technology appraisal TA875 sets out the formal recommendation for semaglutide (Wegovy) in weight management. The key provisions include:

Scotland, Wales and Northern Ireland

NICE guidance applies directly in England. In Scotland, the Scottish Medicines Consortium (SMC) has issued its own assessment. In Wales, NICE guidance is typically adopted by the All Wales Medicines Strategy Group (AWMSG). Northern Ireland generally follows NICE guidance.

The availability of Tier 3 weight management services and specific commissioning arrangements differ between the devolved nations. Contact your GP to understand the referral pathway in your specific area.

Frequently asked questions

Can my GP prescribe Wegovy directly?

No. Under NICE TA875, Wegovy must be initiated within a specialist weight management service. Your GP can refer you to the appropriate service, and in some areas, ongoing prescribing may be transferred to primary care through a shared care agreement once you are established on the medication.

How long does the whole process take?

From initial GP appointment to receiving your first Wegovy injection, the timeline varies widely. In well-resourced areas, it could be as little as 6 to 8 weeks. In areas with long Tier 3 waiting lists, it could take 6 to 18 months. The dose-escalation period adds a further 16 weeks before reaching the full maintenance dose.

Is Wegovy free on the NHS?

If you are prescribed Wegovy through the NHS, you will pay the standard NHS prescription charge of £9.90 per item in England (as of April 2026). Prescriptions are free in Scotland, Wales and Northern Ireland. If you hold a valid medical exemption certificate or prepayment certificate, you will not pay a charge in England either.

What if I lose enough weight — can I stop?

Clinical evidence shows that weight regain is common after discontinuing GLP-1 medications. Your specialist team will discuss the long-term plan with you. Some patients transition to lower-intensity support after achieving their target weight, while others continue medication long-term. The decision is individualised and made collaboratively with your clinical team.

Can I get Wegovy on the NHS if I have type 2 diabetes?

If you have type 2 diabetes, your clinician may consider Ozempic rather than Wegovy, as Ozempic is specifically licensed and funded for diabetes management. However, if weight management is your primary goal and you also have diabetes, you may still be eligible for Wegovy through Tier 3 services. Your clinician will determine the most appropriate option. For the difference between the two, see our Ozempic vs Wegovy comparison.
