If the butyl is buried in plaster/stone and there is nothing flammable
nearby you could run a separate earth wire instead of using the one in
the butyl. This is almost certainly Frowned Upon though it would
confirm the problem is in the butyl wire.

No trips since the landing skt was partly unscrewed & refitted,
the electrician re-arranged the wires slightly - respacing them.

As far as running a new T&E wire goes, it could go the least risky way
rather than the most direct way.

Chimney breast is double - gas fire capability on both sides, so
there are gas pipes on both sides and the usual lead of 1960s :-)

Plan of action is thus 2 stage replacement:
o Landing skt - disconnect butyl-radial, so skt on just PVC-T&E-ring
o Other butyl - when breakfast room redecorated all easily redone

Only thing I need to check in advance is the latest IEE regs on cable
routing w.r.t. distance from room edges/floor/ceiling/skirting etc.
I'm sure TLC used to list a pici, but don't seem to anymore.

Thanks.
