Private weight-loss injection programmes in the UK can cost anywhere from around £80 to £350 or more per month, depending on the medicine, dose and how much clinical support is included.
The difficulty is that providers do not all price their services in the same way.
One clinic may advertise “Wegovy from £79 a month”, while another charges £180 or £220. At first glance, the cheaper option looks obvious.
But the headline price may apply only to the lowest starting dose. It may exclude delivery, consultations, blood tests or follow-up support. Once your dose increases, the monthly price can rise substantially.
Other services work more like a true subscription. You pay one monthly amount that may include medication, prescribing, clinical reviews, nutrition support, delivery and sometimes blood tests.
This guide explains what weight-loss injection subscriptions cost in the UK, what monthly fees normally include, which extras can increase the price and how to compare providers fairly.
How Much Do Weight-Loss Injection Subscriptions Cost?
A useful private UK budgeting range in 2026 is approximately:
| Private treatment | Typical monthly cost |
|---|---|
| Wegovy starting dose | About £80–£130 |
| Wegovy higher or maintenance doses | About £150–£300+ |
| Mounjaro starting dose | About £150–£200 |
| Mounjaro higher doses | About £220–£300+ |
| Comprehensive programme with extra clinical support | About £200–£350+ |
These are broad market ranges rather than fixed prices.
Recent UK provider pricing illustrates the difference.
One provider currently lists Wegovy injections from £115 per month and Mounjaro from £160. At the highest Mounjaro dose, the same provider charges £295.
Another UK service lists Wegovy from £83 at the starting dose, rising to £196 at 2.4mg and £350 for the newer 7.2mg higher maintenance dose.
The most important point is that your first-month price may not resemble your long-term monthly cost.
Our broader guide to how much weight-loss injections cost in the UK compares the medicines themselves in more detail.
Why Does the Monthly Price Increase With the Dose?
Weight-loss injections are normally started at a low dose.
The dose is then increased gradually, a process called titration.
This allows the body time to adjust and may reduce the likelihood or severity of side effects.
For example, Mounjaro usually starts at 2.5mg once weekly before increasing in stages where clinically appropriate.
Wegovy similarly starts at a low weekly dose and is gradually increased.
Higher-strength pens can cost providers more to supply, and pharmacies commonly pass that difference on to patients.
This means a price such as:
“Mounjaro from £159 per month”
does not necessarily mean you will continue paying £159 once the dose increases.
A more realistic comparison is to look at:
- the starting dose;
- mid-range doses;
- the expected maintenance dose;
- delivery fees;
- any monthly membership charge.
Budgeting only around the cheapest first month can make treatment unexpectedly expensive later.
What Does a Weight-Loss Subscription Usually Include?
A legitimate private provider is not simply selling a box of medication.
Weight-loss injections are prescription-only medicines.
The MHRA states that people obtaining GLP-1 medicines privately must have a consultation with a healthcare professional before treatment is prescribed. The clinician should assess whether treatment is appropriate and discuss its risks and benefits.
A typical monthly programme may therefore include several components.
The medication
This is usually the largest part of the monthly cost.
A month's supply generally means one pen containing four weekly doses for injectable treatments such as Wegovy or Mounjaro.
Clinical prescribing
A doctor, prescribing pharmacist or another appropriately qualified prescriber needs to review your medical information and authorise treatment.
Many online providers include this in the medication price rather than charging separately.
Regular clinical reviews
Some services require a short monthly questionnaire before issuing the next prescription.
Others offer video appointments or messaging with a clinician.
Reviews may cover:
- weight change;
- side effects;
- appetite;
- dose tolerance;
- new medication;
- changes in health;
- whether the dose should increase.
This clinical oversight is an important part of safe prescribing rather than an unnecessary administrative step.
Delivery
Some subscriptions include tracked delivery.
Others add approximately £5–£10 per order.
Injectable medicines may require appropriate temperature-controlled packaging depending on the medicine and delivery circumstances.
Are Blood Tests Included?
Usually not in the cheapest online programmes.
This is one area where more expensive subscriptions can differ significantly.
Some premium weight-management programmes include baseline blood testing or periodic monitoring.
Tests may include:
- HbA1c or glucose;
- kidney function;
- liver function;
- cholesterol;
- thyroid tests where appropriate.
However, not everyone requires the same blood tests before starting treatment.
A clinician may decide that tests are particularly important where there is:
- possible diabetes;
- kidney disease;
- liver disease;
- unexplained symptoms;
- significant cardiovascular risk;
- other medication that requires monitoring.
Our guide to blood tests before weight-loss injections explains what may be useful and when.
If blood tests are not included, private testing can add perhaps £50 to several hundred pounds depending on the panel and provider.
What Other Support Might Be Included?
This is where subscription programmes differ most.
Some are essentially pharmacy services:
You complete an assessment, a prescriber approves treatment, the medicine is dispatched and you receive periodic safety checks.
Others offer a wider weight-management programme.
This may include:
- dietitian or nutrition support;
- meal-planning tools;
- exercise guidance;
- behaviour-change coaching;
- weight tracking;
- educational materials;
- messaging with clinicians;
- side-effect advice.
Whether this extra support is worth paying for depends on how much you actually use it.
A £250 monthly programme with frequent dietitian contact may offer good value for someone who wants structured support.
The same programme may be poor value if you never use anything except the prescription.
Our guide to what to eat on Mounjaro or Wegovy covers some of the nutrition issues that become important during treatment.
Watch Out for Introductory Prices
Weight-loss services compete heavily on price.
That means the figure you see in an advert may not be the amount you pay after several months.
Look carefully for terms such as:
- “from £79”;
- “first month only”;
- “new customers”;
- “starter dose price”;
- “with discount code”;
- “subscription price”.
A provider may offer the first dose cheaply but become significantly more expensive once you move to a maintenance dose.
When comparing clinics, ask:
What would I pay each month if I eventually reached the dose commonly used for maintenance?
That gives you a much more realistic idea of affordability.
For example, one UK provider currently charges £160 for Mounjaro 2.5mg but £295 for 15mg — an extra £135 every month.
Over a year, differences like that become substantial.
Subscription vs Pay-As-You-Go
Not every weight-loss clinic uses a true subscription.
Some providers allow you to order one month at a time with no contractual commitment.
Others automatically renew the treatment every month.
Neither model is inherently better.
Pay-as-you-go
This can offer more flexibility.
You order the next month only when you need it and can switch provider relatively easily.
The downside is that you may need to repeat parts of the assessment when ordering and prices may change.
Rolling monthly subscription
Your card is usually charged automatically each month.
This can make treatment convenient, particularly when repeat clinical assessments are integrated into the service.
Check:
- how far in advance you must cancel;
- whether the next pen is automatically dispatched;
- what happens if your prescriber decides treatment should stop;
- whether unused subscription payments are refundable.
Three-, six- or twelve-month plans
Some providers offer discounts in exchange for a longer commitment.
This can lower the monthly price, but be cautious about paying far in advance.
You may need to stop treatment because of side effects, pregnancy, illness or a clinical decision.
Read the cancellation and refund terms before committing to a long package.
Can You Switch Provider to Save Money?
Usually, yes, but another provider still needs to assess you before prescribing.
You should expect to provide information about:
- which medicine you currently use;
- your current dose;
- how long you have taken it;
- your current weight;
- your starting weight;
- any side effects;
- other medicines and health conditions.
A legitimate clinic should not simply sell you whichever dose you request.
The MHRA emphasises that GLP-1 medicines should only be supplied following proper clinical assessment.
Be particularly cautious about providers willing to issue high doses without verifying your previous treatment.
Switching every month purely to chase promotional discounts can also make continuity of care more difficult.
Our comparison of online weight-loss clinics in the UK explains some of the wider factors worth comparing beyond price.
What Safety Support Should Be Included?
A cheap service is not good value if it provides poor clinical oversight.
Your provider should give you clear information about common side effects and what to do if they become severe.
Common GLP-1 and GIP/GLP-1 side effects include:
- nausea;
- vomiting;
- diarrhoea;
- constipation;
- abdominal discomfort;
- reduced appetite.
The MHRA strengthened UK warnings in January 2026 about acute pancreatitis, including rare severe cases.
Seek urgent medical help for severe, persistent abdominal pain, particularly if it spreads to the back and is associated with nausea or vomiting.
If you use tirzepatide, our guide to Mounjaro side effects and warning signs explains what is common and what deserves medical advice.
A responsible service should make it easy to contact a clinician if you develop side effects rather than simply shipping the next pen automatically.
How Much Might a Full Year Cost?
This is often more useful than looking at a monthly starter price.
Imagine a treatment that begins at £120 per month but rises through the year as the dose increases.
Your first year might look broadly like:
| Stage | Example monthly cost |
|---|---|
| Starting dose | £120 |
| Early dose increase | £140 |
| Mid-range dose | £180 |
| Maintenance dose | £220 |
If you eventually spend most of the year around £200 per month, treatment could cost around £2,400 a year.
At £280 per month, the annual cost is approximately £3,360.
Add blood tests, consultations or separate delivery and the total can be higher.
This matters because weight-management medicines are generally not intended as short one- or two-month treatments.
Weight can return after stopping medication, and some patients may need longer-term treatment alongside dietary and lifestyle changes.
The affordability question is therefore not simply:
“Can I pay for the first pen?”
It is:
“Can I afford the likely ongoing cost if the treatment works and I need to continue it?”
Frequently Asked Questions
How much do weight-loss injections cost per month in the UK?
Private treatment commonly costs around £80 to £350 or more per month, depending on the medicine, dose and provider. Starting doses are usually cheaper than higher maintenance doses.
How much does Mounjaro cost per month?
Current UK private examples begin around £150 to £180 at the 2.5mg starting dose and can rise towards £300 per month at higher doses.
How much does Wegovy cost per month?
Starting doses can be available for around £80 to £130 privately, while higher maintenance doses commonly cost around £150 to £250 or more.
Does the monthly price include the medicine?
Usually, yes. Most online weight-loss providers quote a monthly price that includes the prescribed pen. Always check because some specialist clinics charge separate membership or consultation fees.
Are consultations included?
Often they are. Many pharmacy-based services include the initial online medical assessment and repeat prescribing within the price of the medicine. More detailed video consultations may cost extra with some providers.
Are blood tests included?
Usually not in lower-cost programmes. Some comprehensive weight-management subscriptions include blood tests, while others arrange them separately.
Is delivery included?
Sometimes. Some providers include delivery in the headline price, while others add around £5 to £10 per order. Check before comparing prices.
Does the price rise when my dose increases?
Often, yes. This is especially important with Mounjaro and Wegovy because providers frequently charge different prices for each dose.
Do I have to increase to the maximum dose?
No. Dose decisions should depend on response, side effects and clinical judgement. You should not increase your dose simply because the next step appears on a schedule.
Can I cancel a weight-loss subscription?
Rolling subscriptions can generally be cancelled, but providers may require notice before the next payment or dispatch date. Fixed-term plans may have different terms, so read the cancellation policy carefully.
Can I switch weight-loss clinics?
Yes. A new provider will normally reassess your medical history, current treatment and dose before issuing another prescription.
Is the cheapest weight-loss clinic the best option?
Not necessarily. Compare the maintenance-dose price, clinical support, prescribing standards, delivery costs and access to help with side effects as well as the first-month price.
Can I buy Mounjaro or Wegovy without a subscription?
Yes. Some UK providers operate on a pay-as-you-go basis rather than automatic monthly renewal, although you still need appropriate clinical assessment and a prescription.
Can I get weight-loss injections free on the NHS?
Some people can access weight-management medicines through the NHS, but eligibility is more restrictive than private prescribing and access varies by treatment and local pathway. Tirzepatide is being introduced through a phased NHS rollout, initially prioritising people with greater clinical need.
Are online weight-loss subscriptions safe?
They can be when supplied through a legitimate UK healthcare provider with proper prescribing and clinical monitoring. The MHRA warns against buying GLP-1 medicines from social media, beauty salons or unregulated sellers because fake or incorrectly dosed products can cause serious harm.
This guide provides broad UK private-price estimates rather than guaranteed fees. Weight-loss medicine prices change frequently and depend on dose, provider and the clinical services included. Check the full ongoing cost and the provider's regulatory status before starting treatment.
