Weight loss injections in the UK cost between £119 and £330 per month privately, depending on the medication and dose. Mounjaro (tirzepatide) starts at around £149/month, Wegovy (semaglutide) starts at around £119/month, and Nevolat (the Saxenda replacement) starts at around £75/month.

Mounjaro (tirzepatide) prices by dose
Mounjaro is a once-weekly injection from Eli Lilly that targets both GIP and GLP-1 receptors. Clinical trials (SURMOUNT-1) recorded 22.5% average body-weight loss at the highest dose over 72 weeks.
| Dose | Monthly cost | Phase | |------|-------------|-------| | 2.5mg | £149 | Starter (weeks 1–4) | | 5mg | £170 | Escalation | | 7.5mg | £199 | Escalation | | 10mg | £229 | Maintenance | | 12.5mg | £269 | High dose | | 15mg | £329 | Maximum dose |
Most patients escalate over 4–5 months from 2.5mg to a maintenance dose at 5mg, 7.5mg or 10mg. Around half of patients stay at 5mg or 7.5mg long-term; the highest doses are not always needed.

Compare Mounjaro pricesWegovy (semaglutide) prices by dose
Wegovy is a once-weekly injection from Novo Nordisk licensed specifically for weight management. The maintenance dose is 2.4mg.
| Dose | Monthly cost | Phase | |------|-------------|-------| | 0.25mg | £119 | Starter (weeks 1–4) | | 0.5mg | £159 | Escalation (weeks 5–8) | | 1mg | £199 | Escalation (weeks 9–12) | | 1.7mg | £239 | Escalation (weeks 13–16) | | 2.4mg | £279 | Maintenance |
Wegovy uses a 16-week dose-escalation schedule before reaching the 2.4mg maintenance dose. STEP-1 trial data shows 14.9% average body-weight loss over 68 weeks at the 2.4mg dose.
Compare current Wegovy prices across UK pharmacies. Wegovy supply has improved through 2025 and 2026 — most providers now stock all five doses.
Compare Wegovy pricesNevolat (Saxenda replacement) prices
Nevolat replaced Saxenda in many UK supply channels after Saxenda was discontinued. Both contain liraglutide 6mg/ml at the same dose. Nevolat is a daily injection, unlike Mounjaro and Wegovy.
| Dose | Monthly cost (approx) | |------|----------------------| | 0.6mg starter | £75 | | 1.2mg | £95 | | 1.8mg | £130 | | 2.4mg | £160 | | 3mg maintenance | £200 |
Daily dosing means ~30 injections per month versus 4 for weekly GLP-1s. Per-dose injection cost is lower, but consider the convenience trade-off and the lower clinical efficacy versus tirzepatide or higher-dose semaglutide.
What's included in the price?
Always ask any provider for a total monthly cost including:
- The medication and pen
- Initial clinical consultation (most online providers include this; some charge £20–£70 separately)
- Repeat prescriptions and dose escalations
- Follow-up appointments and pharmacist support
- Blood tests (sometimes required, £40–£120 if not bundled)
- Delivery (typically free; some charge £3–£5)
Cheapest headline price is not always cheapest total cost. A £119/month Wegovy 0.25mg deal that excludes consultation can work out more expensive than a £139/month deal that bundles everything.
NHS access to weight loss injections
| Medication | NHS status | Access route | |-----------|-----------|--------------| | Wegovy | Approved (NICE TA875, 2023) | Tier 3 specialist weight management services. BMI ≥35 plus weight-related condition (or BMI ≥30 with disparity adjustment). Long waiting lists. | | Mounjaro | Approved (NICE TA1026, 2024) | Phased rollout from late 2025; highest-BMI patients first. GP referral required. | | Ozempic | Type 2 diabetes only | Not available NHS for weight loss. | | Nevolat / Saxenda | Limited specialist use | Not routinely NHS-funded for weight loss. |
NHS treatment costs £9.90 per prescription in England (April 2026), or free in Scotland, Wales, and Northern Ireland. The trade-off versus private is significant waiting times — many specialist services have 6–18 month queues.

How to compare providers
When comparing UK weight-loss-injection providers, check:
- GPhC registration — confirms the pharmacy is regulated. Verify the GPhC number on the GPhC register.
- Total monthly cost — including consultation, monitoring, follow-ups.
- Dose escalation pricing — does the price scale predictably as you escalate?
- Switching policy — can you switch from Mounjaro to Wegovy or vice versa without re-consultation fees?
- Stock and supply — Mounjaro 12.5mg and 15mg occasionally short on supply. Wegovy now widely stocked.
- Subscription vs pay-per-month — subscriptions can lock in price but may charge if you skip a month.
Long-term cost projection
If you reach the maintenance dose and stay on therapy long-term, budget approximately:
- Mounjaro 10mg maintenance: £2,750/year (£229 × 12)
- Wegovy 2.4mg maintenance: £3,350/year (£279 × 12)
- Nevolat 3mg maintenance: £2,400/year (£200 × 12)
Clinical evidence (STEP-4, SURMOUNT-3 trials) shows weight regain of 70–80% within a year of stopping treatment. Most clinicians treat obesity as a chronic condition. Budgeting only for the starter dose under-counts the true cost.

Frequently asked questions
What is the cheapest weight loss injection in the UK?
Nevolat (the Saxenda replacement, liraglutide 6mg/ml) is the cheapest GLP-1 weight loss injection in the UK at around £75 per month at the starter dose, but it requires daily injections. Among weekly injections, Wegovy (semaglutide) starts at £119 per month at the 0.25mg starter dose, and Mounjaro (tirzepatide) starts at £149 per month at the 2.5mg starter dose. The cheapest published price for each medication is updated daily on TreatCompare from GPhC-registered UK pharmacies.
How much do weight loss injections cost per month in the UK?
Privately, weight loss injections in the UK cost between £119 and £330 per month depending on the medication and dose. Wegovy ranges from £119 (0.25mg starter) to £279 (2.4mg maintenance). Mounjaro ranges from £149 (2.5mg starter) to £329 (15mg). Nevolat (Saxenda replacement) is around £75–£200/month. NHS prescriptions cost £9.90 per item in England (free in Scotland, Wales, Northern Ireland) but eligibility is restricted.
How much is Mounjaro per month in the UK?
Mounjaro costs £149–£329 per month in the UK on a private prescription. The 2.5mg starter dose is around £149, 5mg around £170, 7.5mg around £200, 10mg around £230, 12.5mg around £270, and 15mg around £329. Prices vary by provider — TreatCompare tracks current prices from GPhC-registered UK pharmacies and updates daily.
How much is Wegovy per month in the UK?
Wegovy costs £119–£279 per month privately in the UK depending on dose. The 0.25mg starter is around £119, escalating to £159 for 0.5mg, £199 for 1mg, £239 for 1.7mg, and £279 for the 2.4mg maintenance dose. Wegovy is also available on the NHS through specialist Tier 3 weight management services for eligible patients, where it costs the standard £9.90 NHS prescription charge.
Are weight loss injections available on the NHS?
Yes, but access is restricted. Wegovy was approved by NICE in 2023 (TA875) for adults with BMI ≥35 plus a weight-related condition, accessible via specialist Tier 3 weight management services. Mounjaro was approved by NICE in 2024 (TA1026) and is being rolled out in phases starting with the highest-BMI patients. Both require referral via a GP and have long waiting lists. NHS prescription charges (£9.90 per item in England, free in Wales/Scotland/NI) apply where prescribed.
Why do weight loss injection prices increase as the dose goes up?
Manufacturers price each pen by total medication content, not by dose number. A higher-dose pen contains more active ingredient (e.g. tirzepatide or semaglutide), so the wholesale cost is higher. Most UK private providers pass through this manufacturer pricing structure with a flat margin. As you escalate from starter dose to maintenance, expect monthly costs to rise by £20–£50 per step. Budget for the maintenance dose long-term, not the starter price.
What hidden costs should I budget for?
Beyond the monthly medication price: (1) Initial consultation — included free by most online providers but some charge £20–£70. (2) Blood tests — sometimes required, £40–£120 if not bundled. (3) Dose escalation — costs rise £20–£50 per step over the first 4–5 months. (4) Pharmacist switching fees — some providers charge if you switch back from another medication. Always ask for a total monthly cost including consultation and any monitoring.
How long do I need to keep taking weight loss injections?
Clinical guidance suggests GLP-1 medications work as long as you take them. Stopping typically results in regaining 70–80% of lost weight within 12 months (STEP 4 trial data for semaglutide). Most clinicians treat obesity as a chronic condition requiring long-term management, so you should budget for ongoing costs (£200–£300/month at maintenance dose for Mounjaro or Wegovy) rather than treating it as a short course.
