My rewiring project is *still* ongoing, and I will shortly be
replacing the downstairs ring. The downstairs floor is concreted, and
so all downstairs sockets are going to be dropped from under the first
floor.
Although I realise that current practice dictates that the mains
cabling must be chased into the wall rather than run in the cavity,
(as it is at the moment), I was wondering if I could use the existing
mains cable to pull through some CAT-5. i.e. Is it acceptable to run
Cat5 within a cavity wall?
