For anyone considering building access (namely Paxton) then I would suggest giving Auto Time Systems based in Wigan a call. They've recently "Paxtonified" 10 doors for us, and Im pretty sure they're going to be doing more in future (including a lift!) They aren't the quickest installers but they do nice, tidy work and by gum the guys know their stuff. The Paxton kit is just pure amazing to boot as well

Just wish I could persude the bean counters to Paxtonise our office
