I'm building an extension and planning for the kitchen units. The walls are
from the original outbuilding so will have 45mm of Celotex plus
1.. Do the 1st fix cables get buried in the wall behind the Celotex or
should I make the battens 60mm so providing a void of 25mm and the cables
running between the Celotex and the plasterboard?
2.. I was in a kitchen showroom talking to the kitchen designer about the
points needed for the appliances. It was a working showroom and he showed me
how the point should be located inside the units. It looks like a hole is
drilled in the back of a unit and the cables feed through and a socket
mounted on the unit side. The adjacent appliance is then wired or simply
plugged in to this point. Is this the proper way to do things?
I'm going to need a certificate to hand to building control when the wiring
is completed so am I forced to employ a sparky? What can I do to keep costs
down, is there anything I can do myself?
