How we compare pharmacy prices
Compiled by Health Compare UK using pharmacy websites and information supplied by providers. We cover the pharmacies listed here, rather than every UK pharmacy. Each listing keeps its own check date and confirmation notes.
Compare the same prescribed strength, supply length and purchase type. A confirmed order total includes delivery. An unknown delivery charge or an unconfirmed subscription price is excluded from lowest-total rankings. A bundle's monthly equivalent does not replace its upfront payment.
First-order eligibility and ongoing costs are shown separately where confirmed. An editorial update to this page does not mean every pharmacy price was checked on that date. Confirm the current price, stock and terms with the pharmacy.
Some provider links earn us commission. Payment does not determine the ordering of comparable totals. This is price information, not a recommendation of a medicine or a clinical suitability check.
Information only — not medical advice. These medications are prescription-only in the UK and must be supplied only after a consultation with a qualified healthcare professional. Prices, offers and availability shown can change — always confirm details on the provider’s website.
Frequently asked questions
Comparing weight-loss medication prices — FAQs
How is the total treatment cost calculated?
The total shown for each listing is the medication price plus the delivery charge, displayed separately so you can compare like for like. Health Compare UK never adds commission, booking fees or hidden surcharges to the total.
What is the difference between one-off purchases, subscriptions and bundles?
One-off purchases are individual orders without automatic renewal. Subscriptions renew regularly and may have a minimum commitment; confirm the renewal and cancellation terms. Bundles contain multiple pens or packs paid for upfront, with an effective monthly cost where confirmed. A subscription price is never divided by the commitment length. First-order and repeat prices can differ, and unconfirmed terms remain flagged.
Are the pharmacies listed UK-regulated?
Every provider listed is checked against the GPhC (General Pharmaceutical Council) register. Health Compare UK is not a pharmacy and does not prescribe, recommend or sell medication.
Does affiliate commission affect the price ranking?
No. Listings are ranked by total cost (medication price + delivery) regardless of any affiliate arrangement. Some provider links are affiliate partner links, which may earn a commission at no extra cost to you, but this never changes the cheapest-first order.
How often are prices updated?
Prices and availability change frequently. Each listing shows its last checked date, and only independently verified prices are used for the cheapest-total ranking. Always confirm the live total on the provider’s website before ordering.
Do I need a prescription for weight-loss medication?
Yes. These are prescription-only medicines in the UK and must be supplied only after a consultation with a qualified healthcare professional. Health Compare UK provides price comparison and information only — it does not prescribe or supply medication.
