Passed along to me via email is this downloadable and printable survey, Action for Access.
You go to the website, and follow the instructions for download. The survey can be taken to locations on the map, then matched up (to my understanding) with the online version, to rate local businesses and establishments in the UK on their accessibility.
There are instructions for following up on the information you provide.
If anyone is interested, or has tried this survey and followed up on it, I would be interested to know how successful they found it (or even how accessible they found the survey itself).
