Postcode Search Tool
On the list view page, you can sort the list of GPs by distance to a specified postcode.
For your privacy, the postcode search tool never sends your postcode to our server, nor any other server. Your postcode never leaves your computer. To do this, it downloads a file containing details of all the postcodes in the UK. When you enable the search tool, this download is done automatically, and once it is done you will see the postcode search tool. The file is about 5.5MB.
You can confirm that the postcode is never sent anywhere by watching the network requests in the browser developer tools and seeing that no requests are made when you do a search. Alternatively you can disconnect your computer from the internet after loading the offline postcode search tool, before typing your postcode.
