I've recently started changing normal switches to dimmer switches in
my 1 ear-old home and noticed a very strange wiring technique....

Each of the switches I've changed so far have had the 'loop-through'
wiring done inside the wall switch. Most rooms are fitted with LV
halogen downlighters, so there's no ceiling rose - but surely the
looping should have been done in junction boxes.

Annoyingly, this means there's very little space in the back box for
the extended depth of a dimmer.

Can anyone please give me guidance whether this conforms to 16th
Edition regs, or if I should get another qualified electrician to
inspect.

Regards, Dan

This is known as the "switch feed" method of wiring common in
industrial and commercial wiring. Also good for domestic and the the
method i prefer because hopefully all connection are in the switch
back boxes.
