As-salam alaykum!

This website lists all HMC (Halal Monitoring Committee) certified outlets on a Google map. Only restaurants/take-aways are currently listed, I'll aim to add butchers soon insha Allah.

The data was obtained from the hmc website on Sep 8 2010 and I hope to update it monthly insha Allah.

I've also made a TomTom POI file, which you can download as a zip together with a hmc icon here Unzip the file into your TomTom "Great Britain" or "United Kingdom" map folder and you should be good to go (for an assured halal takeout)!
