Wrap the earth core around the shaft of the screw then tighten screw, put a link of earth cable from this screw to the back box earth terminal aswel.

You'll need an extra piece of green/yellow sleeved wire. Form a screw sized loop on one end and clamp it under that screw head, just as you would if wiring some makes of mains plug. The other end goes into the back box terminal alongside the existing wire.

I'll pre-empt the inevitable question "Where do I get the piece of wire".

Your easiest option is to cannibalize a piece of three core mains flex. You only need a few inches.

I can just imagine, Sunday morning, into Q&B, collar Reg, "I need some 1mm^2 flex".
"Follow me sir,, now, how much do you require ?"
"Two inches please"
