Free GLP‑1 tools for the UK

Four tools that work with UK numbers: NICE BMI thresholds, NHS prescription charges and list prices, and the NHS rules where you live. They run in your browser, with no sign-up.

Written for the UK: prices in £, MHRA licences, NICE guidance, and 999 or NHS 111 for help.

General information, not medical advice. GLP‑1 medicines are prescription-only. A result here is something to take to your GP or another qualified prescriber, who makes the decision.
