wrote:

I recently replaced a plastic light switch with a brass victorian type.
Coming from the ceiling were 2 x red wires and an earth, which
connected securely to the metal mounting box.

Question: There is an earth terminal on the back of the brass
faceplate. Do I need to connect this to the earth on the back box?

Yes. The metal box is then still earthed when the screws holding the
switch are undone.
