Take your pick:

Cut out section of plaster round damaged wire, cut out and replace damaged
section by crimping in new bit of wire, test, and make good.


I would not like to take the risk of crimping mains cable, I would use a
proper juction box.

If the joint is to be inaccessable then that that would be prohibited by
the regs:

[526-04-01] "Except for the following, every connection and joint shall
be accessable for inspection, testing and maintenance

(i) a compound-filled or encapsulated joint
(ii) a connection between a cold tail and a heating element (e.g. a
ceiling and floor heating system, a pipe trace heating system
(iii) a joint made by welding, soldering, brazing or compression tool
(iv) a joint forming part of the equipment complying with the
appropriate product standard"

Move furniture, lift carpets, lift floor, disconnect wiring at accessory,
attempt to pull old cable from conduit, while pulling through new wire,
reterminate at accessory. test, relay floor, carpet, shift furniture.


Which would not be neccessary if the cable had continuos and been installed
in conduit as there would not have been the risk of a short circuit.

There will be when you stick a nail through it.

The normal way of installing conduit is to cut a trough in the wall deep
enough to take the conduit and then plastered over.

Try that on a lath and plaster wall.


It would not be neccessary on a lathe and plaster wall as the cable could be
suspended in the gap between the sides.

Also depricated, and a bit trickey when you need to cross the studs.
