I've not heard good things about these loft conversion companies - apparently it is better to get a decent builder in instead.
A neighbour had a loft converted by one of these companies. When they had finished he tried to turn the light on - nothing. After much investigation it turned out that they hadn't actually put any electrical wiring to the plugs and light sockets
Among other things he had to grout (sorry don't know the technical term) the top tiles on the roof himself (and it looks a right mess!).
It was that bad that some DIY show (or could have been Watchdog) were coming to have a look
