About 15 years ago, after having had a modern consumer unit fitted, and prompted by our electrician, I asked my then energy supplier (Tonik) if our 1968 60 Amp cut-out fuse could be upgraded to 100 Amps, and what additional work/expense would be needed.
I did not know that my request had gone...

Someone's fitted a joint box to move a consumer unit. It's a refreshingly neat job. Din rail, wagos DIN connectors for final circuits etc. It's even fully labelled up.

The old one was fed by a 32A supply, 4mm 6242B (LSOH) cable 32A RCBO. From the rotary isolator, the...
We currently have a property being split into 2 No. flats.
