Our database contains over 8 million records at present - all of which are used to generate the statistics you see on this site. Whilst we do our best to ensure that this database is up to date and correct, the odd error inevitably still slips through the net. Common examples of errors include: exchanges being tagged with the wrong postcode (so the maps center on the wrong locations), exchanges belonging to the wrong county (!) and provider availability being incorrectly listed for an exchange (Please read this first).

So, if you find an error or you think something important is missing, please either use the form below or email directly at sam@samknows.com. Please don't be offended if I take a long time to reply; I receive quite a lot of email.
