What code? bonding conductor

I would use a screw driver.

How will you manage that in the OPs pic.

Holding the block in my left hand, I would insert my screwdriver into the screw slots and apply pressure in a clockwise direction.

Can't even see the screw heads.

Looking forward to the day I ever get to the knowledge base many have on here.

Back of the board has been knocked out leaving internal conductors exposed to a combustible surface.

I haven't seen someone cut the back of a board out before. I'd have thought it would've compromised the manufacturer's design in several non recoverable ways. Stuffed it, in short.

So am I.

Going by your posts mate I'd say you're defiantly already there.

Tbh, I would have just crimped the connection as part of the inspection if I had the time, otherwise a Code 3.

0
and the plastic CU is not combustible?
That is the standard rear knock out on the old crabtree CU

Check tightness of screws, if loose, tighten.

No code

I must say I see many CUs around here installed on wooden battens and all cables coming in through the rear knockout. Usually Wylex or Crabtree. Seems to have been the standard way of doing it for a long time.

Indeed. It's particularly advantageous where you need to add cables later. If access is tight, making a new hole in the side/top/bottom of a CU can be a right pain.

Bit confused where does mounting it on battens come into it. The board in the picture clearly has the back knocked out, is mounted flat leaving conductors exposed to a combustible surface.
