I have tried looking on google but can't find anything. We have a room downstairs that used to be (before we bought the house) accessed from outside but now the door is blocked off and you access it from inside, like a normal room. Up in the corner in a cupboard it has the electricity and gas meters (and the supply pipe?) and directly above is the boiler (i.e in the kitchen above). I am sure it can be cupboarded safely but is it legal and/or safe to use this room as a bedroom? Thanks
