The filllpg site is updated by the users, so if you (or any other users in the area) haven't updated it, it will always be wrong. The beauty of this is that unlike some of the other sites, it lists all outlets as entered by the users and not just the bigger ones. The Autogas site, and it's downloadable POI file for satnavs, only lists filling station forecourts so doesn't include things like Calor and Flogas depots, LPG installers with their own tanks, taxi companies (some taxi companies that run a fleet on LPG will have their own tank and are quite happy to sell you a few litres), etc.
