Wegovy (semaglutide) is now the most affordable licensed weight loss injection in the UK at most dose levels. Since a significant Mounjaro price increase in late 2025, many patients who were on tirzepatide have switched to semaglutide. There are now more Wegovy providers than ever, at a wider range of price points and support levels, and the quality variation between them is significant.

This guide explains how to compare them in terms of what the different tiers actually offer, where the meaningful differences lie, and how to find the right fit for your situation. For current verified pricing across all GPhC-registered UK providers, use the comparethejab.com comparison tool, which is updated regularly as prices change.

1. GPhC and CQC registration: Every legitimate UK Wegovy provider must be GPhC-registered. The prescribing service must be CQC-registered in England. Both are publicly verifiable and should take less than 60 seconds to confirm at pharmacyregulation.org and cqc.org.uk.

2. Cardiovascular screening quality: Wegovy is the only weight loss injection with a cardiovascular risk reduction indication. Providers should be asking about cardiovascular history in their consultation.

3. Support for the full dose escalation: Wegovy's titration schedule runs from 0.25mg to 2.4mg over 20 weeks. Does the provider proactively support each dose increase, or do patients have to self-manage? The weeks around each dose increase are the highest-risk weeks for dropping out.

4. Access to the 7.2mg dose: The MHRA approved Wegovy 7.2mg in January 2026. Not all providers have yet stocked it. If you may eventually need the higher dose, check availability before committing to a provider.

5. Support for patients switching from Mounjaro: A growing number of patients are switching from Mounjaro to Wegovy. Good providers have a clear switching protocol, don't require patients to restart from the starter dose unnecessarily, and are clear about the required gap between last Mounjaro dose and first Wegovy dose.

6. Transparent all-in pricing: Wegovy's dose-dependent pricing structure means the starter dose price is a particularly misleading indicator of ongoing costs. Always confirm the price at the maintenance dose before comparing providers. Visit comparethejab.com for current verified pricing across all registered providers.

Budget providers are typically online pharmacies whose primary function is dispensing. You complete a medical questionnaire, a prescriber reviews it, and the medication is dispatched to you. The clinical process is leaner, follow-up support is usually asynchronous — submit a message, expect a response within 24 to 48 hours — and there's no structured lifestyle programme.

This isn't necessarily the wrong choice. For patients who are confident self-managing, have good health literacy, and already have a GP they can contact for clinical concerns, budget providers offer the same medication at a meaningfully lower cost. They're also worth considering for patients who've already completed the titration phase elsewhere and want to reduce ongoing costs at a stable maintenance dose.

What to watch for: consultation quality varies more in this tier than any other. If a provider mentions automatic approval or a very short questionnaire, look more carefully. Cardiovascular screening depth also varies — worth checking specifically if you have any cardiac history. Cold-chain delivery standards vary too; ask explicitly before ordering.

Best for: cost-conscious, confident self-managers who need medication supply rather than programme support.

Not ideal for: patients who want proactive clinical oversight, structured lifestyle guidance, or fast access to a clinician when something goes wrong.

Programme providers bundle the medication with structured clinical oversight, regular check-ins, app-based tracking, and varying levels of lifestyle support — from digital coaching through to access to registered dietitians. The cost is higher. What you're paying for is everything around the medication, not the medication itself.

Within this tier, the support model varies significantly:

Clinician-led models prioritise GP or prescriber involvement, proactive dose escalation reviews, and robust clinical governance. These suit patients with cardiovascular risk factors or other health conditions where visibility of their weight management treatment genuinely matters, or anyone who wants clinical oversight rather than self-management.

Dietitian-led and behaviour change models add structured nutrition guidance, habit tracking, and accountability coaching. The evidence that medication plus structured lifestyle support produces better and more durable outcomes than medication alone is real. For patients thinking beyond the treatment period — who want habits that outlast the prescription — this tier is worth the additional cost.

Women-focused platforms offer a clinically tailored approach that accounts for hormonal factors such as PCOS, perimenopause, and post-pregnancy weight retention in ways that generic providers typically don't. Given that Wegovy doesn't carry Mounjaro's oral contraceptive interaction warning, these platforms are also well-placed to communicate clearly on contraception and hormonal considerations for female patients.

What to watch for: "programme" is used loosely in this market. Check what's actually included as some providers use the word to describe a basic app with automated messages. Ask whether dietitian access is genuine and structured, whether check-ins involve a clinician or an algorithm, and what the response time is for clinical queries.

Best for: patients who want meaningful clinical oversight, structured lifestyle support, or the strongest possible foundation for long-term results.

Not ideal for: patients whose sole priority is the lowest possible cost for medication supply.

Since the Mounjaro price increase in late 2025, this has become one of the most common patient journeys in the UK weight loss injection market. A few things worth understanding before you switch.

You shouldn't need to restart from the Wegovy 0.25mg starter dose if you've been established on Mounjaro at a higher dose. An equivalent dose should be prescribed based on your Mounjaro dose history and clinical assessment. The required gap between your last Mounjaro dose and your first Wegovy dose varies by provider, so confirm this before committing.

Expect some adjustment period. Even patients who were tolerating Mounjaro well may notice differences in the side effect profile and the timing of effects during the first few weeks on semaglutide. Wegovy's appetite suppression is typically somewhat less pronounced than Mounjaro's at equivalent treatment stages, which is reflected in the clinical trial data. Some patients switching for cost reasons choose to escalate to 7.2mg to partially close that gap.

Don't switch without clinical guidance. Contact your current provider or GP before making the change. The best programme providers in this space have a published switching protocol — ask for it before you commit.

If your main priority is cost: Look at the budget online pharmacy tier. Verify GPhC registration, check that a prescriber genuinely reviews your information rather than an automated system, confirm cold-chain delivery, and use comparethejab.com to compare current verified pricing. Never base a decision on the starter dose price alone.

If you're switching from Mounjaro: Look specifically for a provider with a published Mounjaro-to-Wegovy switching protocol. The key questions: what's the required gap between your last Mounjaro dose and your first Wegovy dose, and will they prescribe at an equivalent higher dose rather than requiring you to restart from 0.25mg? The answers vary significantly between providers and make a real difference to your experience.

If you have cardiovascular disease: Wegovy is the only weight loss injection with a formal cardiovascular risk reduction NICE indication. Choose a provider whose consultation genuinely screens for cardiovascular history and whose clinical team can support appropriate monitoring. Programme providers with regular clinical check-ins are better suited to cardiovascular patients than pure pharmacy-only models.

If you want the 7.2mg dose: The MHRA-approved 7.2mg dose is available from most major providers but is not yet universally stocked. Confirm availability at 7.2mg before committing to a provider if the higher dose is part of your treatment plan. Currently administered as three 2.4mg pens on the same day; a dedicated single 7.2mg pen is in development.

If you want the best evidence for programme outcomes: Look for providers with published, peer-reviewed outcomes data rather than marketing claims. The evidence that structured lifestyle support improves and sustains results is real, but the word "programme" on a website doesn't guarantee meaningful support. Ask what the evidence base actually is.

If you're a woman with hormonal weight management factors: A women-focused provider with a clinical approach that accounts for PCOS, perimenopause, or hormonal weight complications will give you a more tailored experience than a generic service. These platforms are also typically clearer on the contraception considerations specific to Wegovy versus Mounjaro.

If you meet NHS eligibility criteria: It's worth asking your GP about referral to a Tier 3 specialist weight management service. In areas where NHS digital weight management services hold the contract, you may be able to access both Wegovy and dietitian-led support free at the point of use, with a wait of roughly 10 weeks from GP referral. Even if you start privately in the interim, it's worth getting the referral in early.

How do I find the cheapest Wegovy provider in the UK?
Prices change frequently and vary significantly across dose levels, so we don't publish static figures here. Use the comparethejab.com comparison tool for current verified pricing across all GPhC-registered UK providers. Never base a decision on the starter dose price alone — the 2.4mg maintenance dose is what you'll pay for most of your treatment, and the gap between providers at that dose is often larger than at the starter dose.

Which Wegovy provider is best for switching from Mounjaro?
Look for a provider with a published switching protocol that specifies the gap between your last Mounjaro dose and your first Wegovy dose, and confirms you can continue at an equivalent higher dose rather than restarting from 0.25mg. The protocol varies significantly between providers and makes a meaningful difference to your experience. Confirm the details before committing.

Does Wegovy need to be kept cold and will the provider deliver it correctly?
Yes. Wegovy FlexTouch pens must be refrigerated at 2 to 8°C until first use. Legitimate UK providers dispatch Wegovy in temperature-controlled packaging with insulated mailers and cooling inserts. Confirm cold-chain delivery before ordering. If your pen arrives warm, contact the provider and don't use it — medication stored above 30°C for extended periods may have degraded.

Can I get Wegovy 7.2mg from any UK provider?
The MHRA approved Wegovy 7.2mg in January 2026 and it's available privately from most major UK providers, though not all budget online pharmacies have it in stock yet. NHS availability requires a separate NICE appraisal and isn't expected before 2027. Confirm availability at 7.2mg with your chosen provider before committing if the higher dose is part of your treatment plan.
