So can someone def confirm that if you are adding on To an existing (non rcd) circuit then you need to make this rcd protected?

I have a slack handful in my fixings box if I need them.

Heres an interesting thought brought on by these plastic screws .

A house owned by a relative has metal conduit and back boxes which are its cpc for its ring main the sockets have no 'flying earth' and use these screws to get an earth to the accessory should a diyer use these plastic screws then the socket would be unearthed .

wonder if any diyer or Electrical Trainee has done something like that ?
