The right path depends on your health, your eligibility and how quickly you want support. NHS care is free at the point of use, but access to weight loss injections is limited to priority groups, while a private weight loss clinic can assess you sooner, at a cost.
In this article, we’ll compare both routes, explain who qualifies for NHS weight loss injections, and help you decide.
What Weight Loss Support Is Available on the NHS?
The NHS offers several forms of weight management support, including structured weight loss programmes, medicines, and, in some cases, surgery. According to NHS guidance, you may be able to refer yourself to a local weight management service without first seeing a GP.
Can You Get NHS Weight Loss Injections?
Yes, but access is currently limited and being introduced in stages. NICE recommends Mounjaro (tirzepatide) for eligible adults with a BMI of at least 35 and a weight-related health condition. However, NHS England is phasing access over 12 years.
The rollout began with adults who have a BMI of 40 or above and at least four qualifying health conditions, such as hypertension, type 2 diabetes or sleep apnoea. Eligibility is expected to widen each year. Treatment must also include dietary and behavioural support.
What Does a Private Weight Loss Clinic Offer?
A private weight loss clinic gives you another way to access a clinical assessment without having to wait for an NHS treatment pathway to become available. If suitable, you may be prescribed weight loss injections in the UK alongside advice on diet and lifestyle. Private treatment comes at a cost, but it can offer:
- No GP referral needed to book.
- Flexible appointments and regular follow-ups.
- A personalised plan rather than a waiting list.
- Treatment outside current NHS cohorts, where clinically appropriate.
What Should You Check Before Choosing a Provider?
The provider you choose should assess your health properly before recommending treatment. NHS England cites GPhC guidance stating that prescribers cannot rely solely on an online questionnaire when prescribing high-risk medicines such as tirzepatide.
Before booking, look for:
- A GPhC-registered pharmacy or another appropriately regulated prescriber.
- An assessment that considers your medical history, not just an online form.
- Clear information about the cost of treatment before you begin.
- Follow-up appointments and support with diet and lifestyle changes.
NHS or Private: How Do They Compare?
The main differences come down to cost, eligibility and the support available.
- Cost: NHS care is free at the point of use, while private treatment is paid by you.
- Eligibility: NHS access follows strict criteria and a phased rollout. Private providers assess your suitability individually, although treatment is not guaranteed.
- Support: NHS weight loss injections must be accompanied by additional support. The level of support offered privately varies between providers, so check what is included.
Some NHS areas say they can only continue treatment started privately if you meet current NHS criteria.
How to Choose the Right Path
Start by checking whether you meet NHS criteria, then weigh up cost, speed and support:
- Check your BMI and any weight-related health conditions.
- Ask your GP or local weight management service which NHS options are available to you.
- If you do not qualify or prefer not to wait, compare regulated private providers and the support they offer.
- Whichever route you choose, remember that weight loss medicines work alongside changes to diet and physical activity.

Frequently Asked Questions
Can you get weight loss injections on the NHS?
Yes, but access is limited. Mounjaro (tirzepatide) is being introduced in NHS primary care in phases, starting with people who have a very high BMI and several weight-related conditions.
Who is eligible for NHS weight loss injections?
NICE recommends tirzepatide for adults with a BMI of at least 35 and a weight-related condition, with lower BMI thresholds for some ethnic backgrounds. NHS England is phasing access, so check with your GP which group is currently open.
Is a private weight loss clinic better than the NHS?
Neither is better for everyone. The NHS is free but limited by strict criteria, while private care is paid but offers assessment without a GP referral. The right choice depends on your eligibility, budget and the support you need.
Do I need a GP referral for private weight loss treatment?
No. You can book a private weight management consultation at Periville Pharmacy directly, and our pharmacist will assess whether treatment is suitable.
Can the NHS continue my treatment if I start privately?
Not automatically. Some NHS areas say they can only continue treatment started privately if you meet current NHS eligibility criteria after an assessment.
