    Connecting a Welder to the Mains

    I recently had the all of the electrics tested and certified by a reputable, qualified electrician, prior to renting the house out for a while. Everything was considered to be safe and OK. I'm not sure why running a cable through the wall to a socket in the garage is being considered as a...

    Cutting a hole in the wall for a door

    I am planning to build an en suite bathroom in the adjoining bedroom, with access from our bedroom. To do this I will need to cut a gap for the door into the brickwork. The wall itself will be on the top floor of a two storey house but it is a structural load bearing wall (joists in the loft)...
