Guys,

working on a large project where multiple flats are being insulated by means of fitting 100mm insulating boards on top of existing on all external walls.

This means that all sockets, switches etc have to be removed from these walls, and re-instated using fastfix boxes, essy enough.

Problem is though that the cables do not have enough length on them (pyro) so need extended.

Just a quick check to see what you guys think is the best way of doing this. At present I am using 32a lever connectors, taking the earths from the existing metal backbox (core pyro is installed, sheath as earth)

I know other sparks who are using 3 port lever connectors and joining ring in old back box using these connectors leaving only 1 x cable to connect, basically spurring off ring at each socket but I though it would be a better job to individually extend both legs of ring before connecting into new socket

Any possibility of just highering the sockets,thus more length on cable
 
If it was my house i would do it my way , but thinking about it if it,s a large block of flats wouldn,t the council/owners have consulted an electrical consultant to specify how to rectify this problem
