back boxes

Hi Stu, Provided the wall are brick/block, in order to minimise making good, you would be best to use a box cutter fitted to an SDS type drill (which you can hire). This will create a hole to the same dimensions of a 1G or 2G box. The depth of cut and metal box required will depend on the type of socket to be fitted (i.e. cooker and shaver sockets will require a greater depth), but generally a 35mm box should be ok, even for flat plate sockets. For stud/dry lined walls, you will require a dry lining box. The aperture can be created by marking around the back of the box, and the hole cut using a drywall saw. Regards, Simon

You can buy electrical back box sinkers which you fit to a drill on chisel action, this will chase the box in the wall, you can buy double or single boxes great bit of kit screwfix sell for about £140.
