Private weight-loss injections in the UK often cost anywhere from £100 to over £300 per pen, depending on dose. That spread still leaves people hunting for a clear figure on private GLP-1 cost in the UK. You are not being fussy. You are trying to budget for clinician-led care, not a surprise invoice.
The challenge is often straightforward: a starter price looks appealing, but then the dose increases, extra fees emerge, and that initial monthly figure no longer reflects the true cost. We've created this guide to explain what drives the overall cost of a GLP-1 programme and offer a practical approach to planning your budget.
Why private GLP-1 costs in the UK vary so widely
Dose is the biggest mover. Private semaglutide costs in the UK often start lower, then climb as the dose increases. Which? reported private Wegovy costs of about £100 at 0.25 mg and around £240 at the 2.4 mg maintenance dose. The same snapshot put tirzepatide costs in the UK near £150 for 2.5 mg Mounjaro, with 15 mg strengths above £315.
The trend over time matters more than the average monthly cost. GLP-1 doses can go up as often as once a month over the first few months, and the price usually goes up with them. By month four to six, you could be paying more than twice what you paid in month one. If you budget only for the starting price, you may come up short later.
Another key factor is the care model. Some quotes cover just the medication itself, while others include prescribing, follow-up consultations, and delivery. The prices for private weight loss injections in the UK only become truly comparable once you understand exactly what's included in the fee.
The NHS offers weight loss treatment to patients who meet specific criteria, through specialist weight management services, and for some groups, their GP. If you don't meet the criteria, a private service can assess whether you are eligible for private treatment. Each route has varying rules on who can start treatment, the NHS criteria can also vary based on your region.
Private Saxenda prices remain provider-dependent, so treat any liraglutide figure as a snapshot rather than a national average. Variation is the rule.
What a monthly fee should include
Look past the device. The injection is the visible part. The quieter part is clinical judgement, and that is where safety and fit live.
At Hormox, a GPhC-registered pharmacist prescriber reviews every case before a prescription. We do not hand your file to an algorithm. Our clinician-supervised programmes use semaglutide and tirzepatide, adjusted with monitoring built in. Monthly subscription prices include, prescribing, medication and unlimited consultations.
That is how we think about value. The cost of a private Mounjaro prescription, or of semaglutide, is not only the medicine. It is a personalised assessment, a plan tailored to your health profile, and ongoing monitoring as part of your care plan.
Safety belongs in that conversation. Only obtain GLP-1 medicines on a valid prescription, supplied by a GPhC registered pharmacy. The MHRA has warned that fake weight loss medications are offered through social media, beauty salons and websites that don't ask about your medical history to check whether treatment is suitable and safe for you. UK guidance stresses valid prescriptions and registered pharmacies, because falsified GLP-1 medicines sometimes appear in private supply. A regulated service will review your health before prescribing and check in with you throughout your treatment, so any side effects or concerns are managed promptly.

A blueprint for planning your spend in 2026
Here is a practical way to turn a confusing market into a forecast you can live with.
- Start with initiation. Early strengths often sit around £100 to £180 a month, depending on the medicine and how the provider packages care.
- Build in escalation. Maintenance can move into the £240 to £315 range, or higher, especially for higher tirzepatide strengths.
- Itemise everything. List medicine, consultations, blood tests, prescribing, and delivery. If a quote skips a line, add it back.
- Think in six-month blocks. An indicative spread from published monthly ranges is roughly £700 to £1,800 before optional extras. That is a planning band, not a personal quote and not a result.
- Choose continuity. Dose changes and reviews should sit inside the same care plan, with updates you can see over time in a secure portal.
Consider a concrete example. Say you're comparing two options, one that seems more affordable because it just covers the medication alone, and a monthly plan that includes consultations, delivery and medication. Once you add in the extra costs, the cheaper option could end up costing you more in the long run, and the inclusive plan gives you clinical support each time your dose changes.
That is the opportunity. You can stop shopping for the lowest screenshot and start choosing a pathway that matches how clinicians actually use these medicines. Treatment should move slowly, with review, and only after a clinician decides it is appropriate.
What to take away before you enquire
Keep these points in front of you.
- A starter price is not a maintenance price.
- Private Wegovy costs and Mounjaro costs both move with dose.
- Inclusive monthly pricing makes comparison fairer.
- Assessment comes first. This article is not a self-diagnosis tool and not medical advice.
- No clinic should guarantee weight loss or any set result.
We exist to deliver clinical optimisation done properly: evidence-based, individually tailored care, assessed online and delivered discreetly across the UK.
