I've an extension we are going to convert to a kitchen. This will be checked and signed off with building control, however, I have an electrics question.
There's one plug socket in there, wired to the consumer unit under the stairs, in plastic trunking running along the wall at ceiling level.
I know an electrician, who says if I do the hard work (lay the ring main, install the sockets etc), he will safety test it , connect it to the consumer unit and notify building control. Ditto with a radial for the oven.
The existing ring main (for the house) is loose under the floors, resting on the foundations with no clips.
1) Under the floor - can I attach the new cables to the side of the joists where the cables run the length of the room, and, run them under the joists (rather than drilling through them) when running the width of the room? Obviously clipping the cables so they're attached rather than hanging loose.
2) Where the extension joins the house, under the floor, the old exterior wall separates the existing kitchen and extension. Its a good foot thick. It would be easiest for me, access wise, to remove a few bricks down under the double doorway between the rooms, run the cables there, and put a small concrete lintel down to restore the original level. I'd end up with a brick sized hole. Is this an acceptable thing to do to run the cables?
3) I also need to run hot and cold water to the extension. Assuming #2 is acceptable, I'll need to run hot and cold water through the same hole. It it OK for these services to be run together? Any regs on separation or depth?
Thank you
