Choosing where to get a GLP-1 in the UK: NHS, pharmacy or clinic

The NHS, high-street pharmacies, online pharmacies, digital weight clinics and private clinics all supply GLP-1 medicines. Here is how each route works, what you pay for, the rules they must follow, and how to check one before you hand over your details.

The short answer

Check the NHS first: in some cases it is free or costs a prescription charge. If you go private, choose a registered pharmacy or clinic that checks your weight on video, in person or from your records, asks to tell your GP, and tells you the full monthly cost at your top dose before you pay. Never buy from social media, a beauty salon or a "research" website.

Key facts

What you pay
  • NHS in England: the prescription charge, unless you're exempt
  • NHS in Scotland, Wales and Northern Ireland: free
  • Private: the full price of the medicine and the service13

  11. Questions people ask
We don't name, rank or price providers. In the UK, an article that names a prescription-only medicine together with named places to buy it can count as an advert for that medicine.14 So this guide describes the kinds of provider and the rules they follow, so you can check any of them yourself. We take no money from any of them.

Why are there so many providers?

Two weight-loss medicines were licensed in quick succession, NHS access was rationed, and most people turned to private services.

  • Nov 2023Tirzepatide (Mounjaro) licensed for weight management in the UK.19
  • Dec 2024NICE recommended tirzepatide for the NHS in England, to be rolled out to the people who need it most first.5
  • Feb 2025The pharmacy regulator, the General Pharmaceutical Council (GPhC), tightened its rules for online weight-loss prescribing.1
  • Jun 2025GP practices in England could start prescribing Mounjaro to the first priority group.9
  • 2024–2025About 1.6 million adults in England, Wales and Scotland used a GLP-1 to lose weight between early 2024 and early 2025, according to research the medicines regulator cites.18
  • Jun–Aug 2026The first GLP-1 tablets for weight loss were licensed in the UK.20

The GPhC says that access to these medicines "is usually via private services". In a poll it reports, 21% of adults, and 35% of 16 to 34-year-olds, said they had tried to get weight-loss treatment from a pharmacy.3

What kinds of provider are there?

Five main routes, plus one that sells illegally. They differ in who prescribes, what support you get, and who pays.

None of the private routes is automatically safer. A careful online pharmacy can be better than a careless clinic. What matters is whether the parts in the sections below are done properly.

1NHS, through your GP

In England, GP practices can prescribe tirzepatide (Mounjaro) for weight to priority groups, added in stages over several years.5

Usually included
The prescription, plus a compulsory support programme on diet, activity and habits.8,9
Suits
People who meet the current criteria, and anyone with diabetes, heart or kidney problems to manage alongside.
Watch
Areas differ: some ask you to contact your GP, others contact you. Rules differ again in Scotland, Wales and Northern Ireland (see below).8,9
2NHS specialist weight service

A team that brings several kinds of specialist together, often called a tier 3 or tier 4 service. In England, Wegovy for weight is prescribed only here.6

Usually included
Specialist and dietitian care. NICE limits Wegovy for weight in these services to a maximum of 2 years.6
Suits
People with a higher BMI or several health problems, or who are weighing medicine against surgery.
Watch
You need a referral, and waiting lists vary. A separate NHS route to Wegovy now exists for some people with heart disease (see below).7
3High-street pharmacy "online doctor" service

A pharmacy chain's online service: a questionnaire, checks, then a prescription written by a pharmacist or doctor who prescribes for the service.26

Usually included
The consultation, ID and weight checks, the medicine, cold delivery or collection in a store, and an app or support pack.26
Suits
People who don't qualify on the NHS and want a familiar pharmacy.
Watch
How your weight is checked, who prescribes, and the price at your top dose, not the starting dose.
4Online pharmacy or digital weight clinic

Online-only services. Some sell the medicine per pen; others sell a monthly programme with coaching, a nutrition app and check-ins with a clinician.26

Usually included
Medicine, delivery and an app. Programmes add coaching and charge less per month if you sign up for 3, 6 or 12 months.26
Suits
People who want regular coaching between doses.
Watch
Whether it is a registered pharmacy, how long you're tied in, and whether a clinician or only a coach sees you when the dose changes.
5Private clinic, face to face

A private GP, hospital clinic or weight clinic you visit in person.

Usually included
An in-person consultation, sometimes with body-composition checks. The prescription may be filled at a pharmacy of your choice.
Suits
People who want to be weighed and examined in person.
Watch
Services outside pharmacy regulation may need to register with another regulator, such as the Care Quality Commission (CQC) in England.2 Ask which one.
6Employer or insurer schemes

We found no published UK insurer or employer policy that covers GLP-1 medicines for weight, as of October 2026.

Suits
If your workplace offers a health benefit or a private GP service, ask what it covers in writing.
Watch
A benefit that books you into a private service still has to meet the same prescribing rules as any other.1
Not a provider: social media, beauty salons and "research" websites. The medicines regulator (MHRA) says never to buy from beauty salons or social media,4 and that medicines sold as a powder in vials to mix yourself "are not authorised".4 In October 2025 it seized more than 2,000 unlicensed pens from an illegal production site in Northampton.17

Can I get it on the NHS where I live?

It depends on which UK nation you live in, your BMI and your other health conditions. Rules are changing, so ask your GP practice how your area works.

BMI (body mass index) is your weight in kg divided by your height in metres squared. In the NHS rules, the BMI needed is 2.5 points lower for people of South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean background.5,25

England
  • Mounjaro through your GP, in stages. From June 2025: a BMI of 40 or more with at least 4 of these 5 conditions: high blood pressure, abnormal blood fats, sleep apnoea, heart or circulation disease, type 2 diabetes. From around June 2026: BMI 35 to 39.9 with 4 of them. From around March 2027: BMI 40 or more with 3.5
  • Wegovy for weight only in a specialist weight service, for up to 2 years, with a BMI of 35 or more and a weight-related condition (or 30 to 34.9 if you meet the referral criteria).6
  • Wegovy for heart protection: NICE guidance from May 2026 covers adults with a BMI of 27 or more who have had a heart attack or stroke, or have narrowed leg arteries causing symptoms.7
Scotland
  • The Scottish Medicines Consortium accepted Mounjaro for restricted use in adults with a BMI of 30 or more and at least one weight-related condition, with a lower BMI possibly more suitable for minority ethnic groups.10
  • Health boards decide how and when to offer it, so ask your GP practice.
Wales
  • Since October 2025, Mounjaro has been offered to some groups, such as people waiting for time-sensitive surgery or a transplant, women seeking fertility treatment, and people with severe asthma or severe sleep apnoea.11
  • Before that it was only through specialist weight services.11
Northern Ireland
  • A Health Service leaflet from April 2025 said Mounjaro was not yet available for obesity and would be brought in over a number of years. It said Wegovy and Saxenda weren't available either, because there was no specialist weight service.12
  • We couldn't find a newer update. Ask your GP surgery.

These are points to discuss with your GP, not a promise that you qualify. In England the NHS route comes with a support programme you must take part in.8,9 If you already pay privately, an NHS prescription is possible only if you meet the NHS criteria when you're assessed.9 Guide 4 helps you think through whether a GLP-1 fits you at all.

How does a private online service run?

Most follow the same steps. The ones to slow down at are the checks in steps 2 and 3.

1
Online questionnaireYour health history, medicines, height and weight. On its own, this is not enough to prescribe.1
2
Checking your weight and historyBy video, in person, from your medical records, or by contacting your GP.2
3
The prescriber decidesA doctor, or a pharmacist or nurse prescriber. If they can't check what you told them, they should send you elsewhere to be assessed.2
4
Telling your GPWith your consent, the prescriber shares the prescription with your GP or regular prescriber.2
5
Medicine sent coldDelivered in cold packaging or collected from a pharmacy.
6
Check-ins and repeat suppliesYour progress should be checked and your weight confirmed again from time to time.2

Based on the pharmacy regulator's guidance for online weight-loss services.1,2

The steps look the same from the outside. The differences are in who does each one and how carefully, which the next section covers.

What should each part look like?

Six parts, each with what good looks like and the warning sign to watch for.

1The prescriber

  • You can't find out who prescribesPrescribing problems were the biggest single group of concerns the pharmacy regulator received about weight-loss medicines: 27 in every 100.3
    You can get the prescriber's name and registration number, and check it on the right register. A pharmacist who prescribes shows "Independent Prescriber" on the GPhC register.21

2Checking your weight

  • Only a form, a phone call or a photoThe regulator says a phone call "would not be appropriate", and a photo or pre-recorded video you send shouldn't be used on its own to check your weight.2
    Your weight, height or BMI is checked by video, in person, from your medical records, or with your GP before the first supply.1,2
  • A lower BMI accepted with no proofThe licence for weight loss starts at a BMI of 30, or 27 with a weight-related condition.23
    If a condition is the reason you qualify at a lower BMI, the prescriber checks your medical history, not just your word.2

3Your GP and your records

  • Nobody asks about your GPYour GP may be treating you for things that matter, such as diabetes or other medicines.
    The prescriber asks your consent to tell your GP. If you say no, or have no GP, they decide whether it's still safe to prescribe and record why.2

4The medicine

  • Vials, powders, or a pen that looks wrongIn 2026 a fake Mounjaro 15 mg pen was supplied through one UK online pharmacy. It was spotted because the dose knob came off during use.16
    A licensed pen or tablet in its packaging, with a leaflet, sent cold where the pack says so. If anything seems wrong, don't use it and report it to the Yellow Card scheme.
  • Cold-chain or dispensing slipsProduct quality, cold-chain failures and dispensing errors are among the concerns the regulator receives.3
    The service tells you how the pen is packed and what to do if it arrives warm. Guide 8 covers storage.

5Diet, coaching and the app

  • The medicine sold as the whole answerNICE recommends these medicines alongside a reduced-calorie diet and more physical activity, not instead of them.5,6
    Advice on eating enough protein and doing strength exercise to protect muscle (see Guide 8). Questions about side effects or your dose go to a clinician, not only an app or a coach.

6Reviews and stopping

  • Doses keep going up with no reviewRepeat supplies sent on a timer, with no one asking how you are.
    A review at about 6 months. NICE says to consider stopping semaglutide if less than 5% of your starting weight has been lost by then, and to weigh up carrying on with tirzepatide.5,6 A plan for stopping is part of the service (see Guide 9).

How do they charge?

On the NHS you pay a prescription charge or nothing. Privately, the medicine is the biggest part of the bill, and its price rises as your dose goes up.

We don't publish any provider's prices. They change often and depend on the plan. Below is how the fees are built.

NHS in EnglandThe prescription charge is £9.90 per item. A 12-month prepayment certificate costs £114.50. If you have diabetes treated with medicine, you can get a certificate that makes your prescriptions free.13
NHS in Scotland, Wales and Northern IrelandPrescriptions are free.13
Private, priced per penOne price per pen of 4 weekly doses, higher for higher doses. Delivery may be extra.26
Private monthly programmeMedicine plus coaching for a monthly fee, cheaper per month if you commit to 3, 6 or 12 months, but you're tied in.26

Free NHS prescriptions don't apply to private ones: privately, you pay the full price.13

Ask one question before you pay: "What will I pay each month, all in, once I'm on my full dose?" A price on the starting dose looks cheaper than it will be. At the maker's list price published by NICE, a top-dose Mounjaro pen (£330) costs about 2.5 times a starting-dose pen (£133), before VAT and the service's own charges.5 Then put your numbers into the GLP-1 cost calculator.

Budget in years, not months: Guide 9 explains what happens to your weight when you stop, and what years of treatment cost. A long prepaid plan isn't automatically good value if you may need to stop or change medicine early.

What are the rules in the UK?

Every provider, online or not, works under the same rules on prescribing, online checks and advertising.

All GLP-1 medicines are prescription-only.4 The MHRA says they should be used only if you are overweight or have diabetes, "not if you want to lose weight for aesthetic or cosmetic purposes".4

Online prescribing (GPhC, February 2025)
  • Weight-loss medicines are now on the regulator's list of higher-risk medicines for online supply.1
  • The prescriber can't rely on an online questionnaire alone. They must check your weight, height or BMI independently: by video, in person, from your records, or with your GP.1,2
  • With your consent, they share the prescription with your regular prescriber.2

These rules cover pharmacies in Great Britain. Northern Ireland's pharmacies have their own regulator.4

Who the licence is for
  • The weight-loss licence covers adults with a BMI of 30 or more, or 27 to 29.9 with at least one weight-related condition.23
  • The licence itself has no lower cut-off for ethnicity. The lower NICE thresholds are for NHS eligibility.23,25
  • Ozempic and Rybelsus are licensed in the UK for type 2 diabetes, not weight loss.4
Advertising
  • Prescription-only medicines can't be advertised to the public.15
  • Regulators treat words such as "weight-loss injection" or "GLP-1", and pictures of an injection pen, as promoting these medicines, even without a brand name.15
Enforcement
  • The GPhC received 1,307 concerns about weight-loss medicines between January 2024 and December 2025. About 1 in 20 of its pharmacy inspection reports mentioned weight management.3
  • The MHRA seizes illegally traded medicines, and in 2026 warned about a fake Mounjaro pen supplied through an online pharmacy.16,17

How do I check a provider?

Every pharmacy and prescriber in the UK should be on a public register. Look them up before you share your details.

Pharmacies and pharmacists (Great Britain)Search the GPhC registers by name or registration number. Pharmacy premises are listed too.21,4
Pharmacies in Northern IrelandCheck with the Pharmaceutical Society of Northern Ireland (PSNI).4
DoctorsSearch the General Medical Council (GMC) register by name or GMC number.22
Nurse prescribersSearch the Nursing and Midwifery Council register.22
Clinics in England that aren't pharmaciesAsk which regulator they're registered with, for example the Care Quality Commission.2
Something went wrong?Report side effects or a suspect pen to the Yellow Card scheme, and concerns about a pharmacy to the GPhC.24,21

Red flags

Any one of these is a reason to stop and look elsewhere.

  • "No prescription needed", or sold on social mediaThe MHRA says never to buy from beauty salons or social media.4
    Supplies only after a clinical assessment and a prescription.4
  • Vials, powders, "research peptides" or retatrutideRetatrutide has no UK licence, and the MHRA has seized unlicensed pens of it.17 Vials to mix yourself are not authorised.4
    Supplies only licensed medicines, in their own packs.
  • No real check of your weightA questionnaire alone, a phone call, or a photo you send.2
    Checks by video, in person, from your records or with your GP.2
  • Sold for looks, or for a few pounds before a holidayThe MHRA says these medicines are not for cosmetic weight loss.4
    Prescribes only within the licence, and says no when you don't meet it.23
  • Promises of how much you'll loseTrial results are averages: some people lose much more, some very little.
    Quotes trial results with the trial's name, length and dose, and says results vary. See Guide 2.

Already signed up and worried? Don't stop your medicine without talking to a doctor first.4 Report side effects or a suspect pen to the Yellow Card scheme,24 and concerns about a pharmacy to the GPhC.21

Questions people ask

Before you sign up

Can I get a GLP-1 on the NHS instead of paying?

Possibly. It depends on where you live, your BMI and your other health conditions. In England, GP prescribing of Mounjaro is being opened up to more people in stages, and Wegovy for weight is through specialist services.5,6 Ask your GP practice how it works in your area.8,9

Is an online pharmacy as safe as my GP?

It can be. Since February 2025, online prescribers must check your weight by video, in person, from your records or with your GP, and should ask to share the prescription with your GP.1,2 What matters is a registered pharmacy, a named prescriber and real checks.

Why do they want to contact my GP?

The regulator expects the prescriber to share the prescription with your regular prescriber, with your consent.2 Your GP may be treating conditions or prescribing medicines that matter, such as diabetes treatment.

Do I need a programme, or just a prescriber?

You need a prescriber. A programme adds coaching and an app, which some people find helpful. NICE recommends these medicines alongside a reduced-calorie diet and more physical activity, so support with eating and exercise matters wherever it comes from.5,6

Once you're in

Can my GP take over my private prescription?

Only if you meet the NHS criteria when you are assessed. NHS pages say that people who buy privately may be able to get an NHS prescription if they qualify, but there is no automatic switch.9

What should happen at my 6-month review?

The prescriber checks your weight and side effects. NICE says to consider stopping semaglutide if you've lost less than 5% of your starting weight after 6 months, and for tirzepatide to decide whether to carry on, weighing up benefits and risks.5,6

What if I'm told a GLP-1 isn't right for me?

That's the check working. Ask what to do instead; Guide 3 covers the other options. If the prescriber couldn't confirm what they needed, they should direct you to another care provider for a proper assessment.2

Before you move on

  • Check the NHS route where you live first.
  • Find the pharmacy and prescriber on a public register.
  • Expect a real weight check, and a request to tell your GP.
  • Get the all-in monthly cost at your full dose, in writing.
