Hi

My friend is completing his conservatory which has a roofed ceiling.
It is necessary to route ring main cable in the roof space between the
insulation and the plaster board. Two existing cables had to be
extended and joins are made in the roof space using terminal block in
choc-boxes. My friend wants to know whether it is permissable to have
choc-boxes in this space because when the plasterboard is fitted the
boxes will be inaccessable (without removing the boards).

Is there any regulation that forbids such an arrangement?

Is it necessary to get a Part P inspection before the plaster boards
are fitted?

Yes. Inaccessible connections should be crimped, soldered, or brazed.
Crimping is what's normally done in your case.

That's up to your building control officer (or whoever
he's arranged to do the Part P inspection on his behalf).

How is 'inaccessible' defined Andrew? For example, a chocky block tucked
into a ceiling void above a ceiling rose?

It's not strictly defined.
My take on it is something you can can't get
to as part of an electrical system inspection.
I think what you describe would be OK from this
point of view, but something that required
damaging furnishings/decorations would not.

As to whether you should be stuffing a choc block
unprotected into a ceiling void -- that's a
different matter. I know most electricians do.
