NHS vs Private GLP-1 in the UK: Eligibility, Waiting Times and Cost (2026)

Can you get Wegovy or Mounjaro on the NHS? This guide sets out exactly who qualifies, what the waiting times look like, what going private costs, and the honest pros and cons of each route.

Last updated: April 2026 | 11 min read

One of the most common questions people ask when they first start researching GLP-1 medications is whether they can get them on the NHS — and if not, what it actually costs to go private. The honest answer is more nuanced than most sources admit: NHS access exists but is highly restricted, and the criteria are strict enough that the vast majority of people end up going private.

This guide sets out exactly what the NHS criteria are for Wegovy and Mounjaro in 2026, what the realistic waiting times look like, what going private costs, and the pros and cons of each route — so you can make an informed decision.

Can You Get GLP-1 Medications on the NHS?

Yes — but eligibility is far more restricted than many people expect.

Wegovy (semaglutide for weight loss)

NICE approved Wegovy for NHS use in March 2023. However, the NHS has not simply started prescribing it to everyone who qualifies. Instead, NHS England has established a phased rollout through specialist Tier 3 and Tier 4 weight management services. This means:

• Wegovy is not currently available from GPs — you cannot ask your GP to prescribe it directly
• You must be referred to a specialist NHS weight management service
• Your local Integrated Care Board (ICB) must have commissioned the Tier 3 service that includes Wegovy — not all areas of England have done so yet
• Scotland, Wales and Northern Ireland have separate commissioning arrangements and availability varies

Mounjaro (tirzepatide)

NICE recommended Mounjaro for NHS use in December 2024. Like Wegovy, it can only be prescribed through specialist weight management services, not by GPs. NHS availability is even more limited than Wegovy at present as commissioning is still being rolled out.

Ozempic (semaglutide for diabetes)

Ozempic is NHS-licensed specifically for type 2 diabetes management. If you have type 2 diabetes and your GP prescribes Ozempic for blood sugar control, you may also experience weight loss as a benefit. However, Ozempic is not licensed for weight loss on the NHS — it's only prescribed when clinically indicated for diabetes.

NHS Eligibility Criteria for Wegovy and Mounjaro

To be eligible for NHS Wegovy or Mounjaro through a specialist service, you typically need to meet all of the following:

• BMI ≥ 35 kg/m² (or ≥ 30 kg/m² in certain high-risk groups, such as people of South Asian, Chinese, Middle Eastern, Black African or Black Caribbean origin)
• At least one weight-related health condition — such as type 2 diabetes, pre-diabetes, hypertension, obstructive sleep apnoea, cardiovascular disease, or non-alcoholic fatty liver disease
• Engagement with a Tier 3 weight management programme — you typically need to have engaged with structured lifestyle intervention (diet, exercise, behavioural support) before medication is added
• No contraindications — you should not have a personal or family history of medullary thyroid carcinoma or MEN2, pancreatitis, or other contraindications listed in the prescribing guidance

If your BMI is between 30–34.9 without a qualifying comorbidity, NHS access is currently very unlikely regardless of where you live.

NHS Waiting Times: What to Realistically Expect

This is where many people get a shock. Even if you meet the eligibility criteria, the waiting list for specialist Tier 3 weight management services can be significant.

• Tier 3 service waiting times: 6–18 months in most areas of England, with some areas reporting waits over 2 years
• Getting the referral: Your GP may not be aware of local commissioning arrangements or may not refer proactively — you may need to ask explicitly
• Availability varies significantly by area: Some ICBs have well-funded, accessible Tier 3 services. Others have long waits or have not yet commissioned Mounjaro specifically
• Wales and Scotland: Some areas have better access than England. NHS Scotland has generally moved faster on implementation

How to find out about local NHS access

• Ask your GP whether your local ICB has commissioned Tier 3 weight management services including GLP-1 prescribing
• Check your ICB's website — most publish their weight management commissioning arrangements
• Contact the NHS England helpline or use the NHS website's service finder for weight management services in your area

Going Private: What Does It Actually Cost?

For the majority of people who don't meet NHS criteria or who can't wait 12–18 months, private prescribing through an online clinic is the practical route. Here's what to expect on cost:

Wegovy (semaglutide) private costs 2026

Mounjaro (tirzepatide) private costs 2026

These prices represent the medication cost only. Some clinics include consultation fees in the first month; others charge separately (typically £50–£150 for the initial consultation).

NHS vs Private: A Direct Comparison

The Real Pros and Cons

NHS: the case for waiting

• Cost: The difference in annual cost is £0 vs £2,000–£4,000. For a medication many people will need for years, this is significant
• Support quality: NHS Tier 3 services provide genuinely comprehensive multi-disciplinary support — dietitians, behavioural psychologists, specialist nurses — that most private clinics can't match
• Long-term security: Once on the NHS, you're not at risk of stopping treatment because of cost
• Monitoring: Regular bloods, blood pressure checks and clinical reviews come as standard

NHS: the downsides

• Waiting time: 6–24 months is a long time when you're ready to start treatment now
• Eligibility restrictions: Most people with a BMI in the 30–35 range with no qualifying comorbidity cannot access NHS treatment
• Postcode lottery: The quality and availability of services varies dramatically between ICBs
• Uncertainty: NHS commissioning of these medications is still evolving — there's no guarantee of continued funding if you're mid-treatment when policy changes

Private: the case for going private now

• Speed: Most clinics can have you prescribed and dosed within 48–72 hours of completing an online consultation
• Accessibility: Available nationwide regardless of where you live
• Wider eligibility: Most private clinics will prescribe to people with a BMI ≥ 30, sometimes lower with comorbidities
• Convenience: Remote consultations, home delivery, app-based support — fits around busy lives

Private: the downsides

• Cost: £99–£375/month is a significant recurring expense. Annual cost at maintenance dose: £2,000–£4,500
• Variable quality: Some private clinics are little more than prescription dispensers. Choose carefully — look for ones with real clinical support (see our clinic comparison)
• No continuity guarantee: If you can't afford one month, treatment stops
• Less monitoring: Private clinics vary in how much blood monitoring and clinical follow-up they include

Can You Be on Both at the Same Time?

No. You cannot receive NHS-funded GLP-1 medication and pay for additional private prescriptions simultaneously for the same condition. If you start on the NHS, your private prescription would need to stop. If you start privately and are later offered an NHS place, you can choose to transfer — but you'd stop private treatment first.

Some people start privately while on an NHS waiting list, with the intention of transferring when their NHS place comes through. There's nothing wrong with this approach, though the transition requires coordination with both your private clinic and your NHS team.

How to Maximise Your Chances of NHS Access

• Ask your GP directly — not all GPs proactively refer. Be specific: ask whether your ICB has commissioned Tier 3 weight management services including GLP-1 prescribing
• Get your BMI and comorbidities documented — make sure your GP has a current record of your weight, BMI, and any qualifying conditions (blood pressure, HbA1c, sleep apnoea diagnosis etc)
• Engage with Tier 2 services first — some ICBs require evidence of Tier 2 (group-based lifestyle support) before referring to Tier 3. Ask your GP if this applies in your area
• Chase the referral — NHS referrals can go quiet for months. Follow up with your GP every 6–8 weeks if you've been told a referral has been sent
• Know your rights — if you meet NICE eligibility criteria and your ICB has commissioned the service, you have a right to be referred. If your GP refuses, you can request a second opinion or contact your ICB's patient services team

Frequently Asked Questions

My GP says I don't qualify for NHS Wegovy. Are they right?
Possibly, but not always. GP knowledge of the specific NICE criteria and local commissioning arrangements varies considerably. If you believe you meet the criteria (BMI ≥35 with a comorbidity, or ≥30 in the qualifying ethnic groups), it's worth asking your GP to check the local commissioning policy directly, or requesting a second opinion.

If I lose weight privately, will the NHS cover maintenance?
Not automatically. NHS prescribing is subject to ongoing eligibility assessment. If you've lost significant weight privately and your BMI has dropped below the NHS threshold, you'd no longer qualify — even though stopping medication typically leads to weight regain.

Are private online clinics safe?
Regulated ones, yes. Look for clinics registered with the CQC (Care Quality Commission) and using GPhC-registered pharmacies. All clinics listed in our comparison tool meet these standards.

Will GPs ever prescribe GLP-1s directly?
This is an active area of NHS policy. NHS England has been piloting primary care prescribing models, but as of April 2026, GLP-1 prescribing for weight loss remains restricted to specialist services. This may change within 2–3 years as more evidence accumulates and commissioning matures.

What happens if the NHS stops funding my treatment?
ICBs can in theory withdraw commissioning, though this is rare mid-treatment. Most have grandfathering arrangements for existing patients. If this happens to you, you would need to either transfer to private prescribing or manage the medication discontinuation carefully with your clinical team.

GLP1Guide.live does not provide medical advice. NHS commissioning arrangements change regularly — always check with your GP and local ICB for current eligibility and availability. Private clinic pricing is accurate as of April 2026 and subject to change.
