My wife is desperate to have a garage door opener, and she's found this kit at B&Q. Can anyone advise on how easy/straightforward these things are to install? It'll be me (and most likely my Dad) installing it, and I think between us we're reasonably capable, but I haven't done anything of this kind of scale before, and I imagine if it comes down and whacks my wife's new car it'll be my fault...
Also, regarding the electrics is it something I need an electrician to come and wire up for me? I have two fluorescent tubes in the garage ceiling, but I'm guessing if I run a spur from them down to the GDO, we'll need to leave the lights on all the time? (I'm in the UK if that makes a difference)
