Proper Pinning Of Cables In Loft And Under Floor

[SpeedingO]

I'm adding a socket to a ring and also moving a light switch. The socket is an upstairs socket so the cables run under the floor. I note the old clips are metal, I guess fireproof? What are the do's and don'ts of securing cables under the floor?

Also, the lighting cable I'm moving (moving switch to other side of door) is running through the loft, the old stuff is just as the crow flies which is going to be a pain when I come to insulate the loft. What are the proper securing requirements for loft space cable?

Many Thanks!

It is likely the clips are just old from when metal was all they had.

As for dos and don'ts securing cables under the floor and in the loft; there are virtually no dos - common sense.
