Earth from cutout to MET - who is responsible?

Yep, and it just fell out when I brushed past it, odd isn't it. I can confirm that it is now possible to reach the terminal screws.

Fair enough - that's obviously what matters!

Kind Regards, John

I may just be seeing things, but when I look very carefully at the photo (and clean the area of my monitor) I can barely see what look like two small circular features on the recessed area that seem to line up with the terminals. I guess these are holes allowing access to the terminal screws.

You must be seeing things, as there definitely were no such features on the recessed area, and from what I can see the recessed area definitely is designed to come out as one piece - very similar to the knockouts on a surface mount box (and indeed it looks to have come out about as cleanly too).

(edit: clarified I meant no features, not no recessed area).

A lot have been made PME even though appears as TN-S in the premises.

Given that the safest approach is "assume that it is, or will be PME at some point further upstream", the old cable has now been replaced with some 16mm earth cable to a new 8 way MET, which then goes onto my gas bonding (looks to be 10mm) and CU (16mm). Incidentally the lead water pipe doesn't appear to be bonded, although this will be getting replaced with a plastic one in a few months so I'll likely leave this as it is (and the boiler appears to be providing some form of bonding with the water anyway).

The old cable was around 2.5mm - presumably some old imperial size as it was sheathed solid green. Quite scary if it really is PME.
