Can anyone tell me if extending an existing ring circuit needs to be done by a qualified electricitian (who can self certify) or is notifiable under building regs? or can it be done by a competant DIY'er?
The existing ring circuit is on a B32 MCB, 2.5mm2 cable with 5 double sockets + 1 single socket. I want to extend it to have an additional 3 double sockets.
Don't know the overall length of the ring, but it is quite long as the sockets are at the back of the house and the CU by the front door.
In addition to the query above, I have also discoved that the existing mono pitched roof over my kitchen does not have insulation. I have pulled down the ceiling and am going to be installing insulation between and under the existing rafters. The majority of the existing cabling (with the exception of some juction boxes) will be within the 70mm ventilated void above the new insulation, however the cables will need to drop through the insulation where the ring circuit drops down at the walls and also at the lighting rose postions. Is this acceptable?
Thanks
