Gideon,
This is not good at all!.
I'm not sure the Power Authority would be too keen on thier Service Entrance and Main fuse being covered up like that.
I'd have to agree with britspark when mentioning that conduit socket on the double outlet.
Seems as there are 2 cables entering that socket, would this be a ring circuit?.
Reason I ask that is because the plug on the right side of the socket looks like a moulded type that is used on extension cords.
Which brings me to the question, do you have to have a fused plug on an extension cord in the UK?.
In the bottom picture, it looks like there wasn't a lot of fore-thought in selecting a position for that Hager switch-board.
By the looks of things, it probably could have been installed on the same wall where it is now, but up higher (above the top of the MEM board).
BTW, I think the Trunking might be full. [Linked Image]
