Affiliate Disclosure
Last updated: March 2026
How WeightCompare earns revenue
WeightCompare is a free price comparison service. We earn revenue through affiliate commissions — when you click a link to a pharmacy on our site and subsequently make a purchase, we may receive a small referral fee from that pharmacy. This costs you nothing extra and does not affect the price you pay.
Our rankings are independent
Commercial relationships with pharmacies have no influence on how we rank, order, or display listings. Pharmacies are sorted by price — cheapest first — based on publicly available data we collect independently. We do not accept payment from any pharmacy to improve their position in our comparison tables, nor do we suppress or demote listings based on whether a commercial arrangement exists.
Pricing accuracy
We check prices regularly across all listed pharmacies and make every effort to keep our data accurate and current. However, pharmacy pricing can change at any time without notice. We recommend verifying the final price directly on the pharmacy's website before completing a purchase. WeightCompare cannot be held responsible for discrepancies between prices shown on our site and those on individual pharmacy websites.
Pharmacy verification
Every pharmacy listed on WeightCompare is verified against the General Pharmaceutical Council (GPhC) register. We display each pharmacy's GPhC registration number so you can independently confirm their regulatory status. While we take care to list only legitimately registered providers, we encourage users to carry out their own checks before making a purchase.
Not medical advice
The content on WeightCompare is for informational and comparison purposes only. Nothing on this site should be interpreted as medical advice, a diagnosis, or a recommendation to use any particular medication or treatment. All medications featured are prescription-only medicines (POM) and require a valid prescription from a qualified healthcare professional. Always speak with your GP, pharmacist, or another registered prescriber before starting, changing, or stopping any treatment.
Coverage limitations
While we aim to include as many UK pharmacies as possible, our listings may not cover every provider. Some pharmacies — particularly those without a significant online presence — may not appear on our site. Inclusion or exclusion of a pharmacy is not an endorsement or criticism of their services.
Discount codes
Where displayed, discount codes are sourced from publicly available promotions or direct partnerships with pharmacies. We verify codes where possible, but availability and terms may change without notice. Always check the terms and conditions on the pharmacy's website before applying a code.
