Probably barking up the wrong tree here but those Henley/connector blocks look odd, the wires coming out at least; outer 2 appear to go to the switch fuse, inner 2 to the isolator - would have thought it'd be 2 left, 2 right ,but then I remembered its line & neutral so should it not be a case of 1 & 3 to switch fuse (or isolator) and 2&4 to either the isolator (or switch fuse) as it stands you've got 1&4 used together at the switch fuse and 2&3 at the isolator.
As I say I'm probably wrong but it didn't look right to me.
It doesn't matter, the service connector blocks are just commoning blocks and don't have any specific terminal designations. Whilst it would be nice for each one to be connected in logical order it doesn't make any difference functionally.
The bigger question as far as that isolator is concerned is why the smaller CU has been connected before the DP isolator? The whole point of having a seperate isolator fitted is to be able to isolate the whole installation from the incoming supply.
