At work in one of our high rise buildings every apartment in the building has a meter and consumer unit for regular peak supply, and an off peak meter and consumer unit for storage heaters and off peak immersion. The off peak feeds are controlled by a cyclometer so are switched on and off by a Scottish Power computer when demand is low and energy cheaper rather than a standard 7-11 (although they have just stopped supporting this so the off peaks are now permanently on until we get the meters upgraded).

The on peak feed for the immersion doesn't go to either consumer unit. Instead, it comes from the on peak meter in 6mm (I think) tails into an unswitched fused spur with a 13A fuse and then 2.5mm t&e to a double pole switch for the immersion- it is like this in every apartment in the building.

What coding would you give this on an EICR? What regs would it be against? At any point would this have been an acceptable installation? It seems so wrong to not be going through a db first.
 
It may not have and may still not breach any regulations
Rcd if cables hidden below 50mm
 
I would have two concerns. a) can it be isolated (as it's domestic premises) and b) does the fused spur have adequate short-circuit rating to withstand being backed up only by the service cutout. Interested to hear other views on this.

The FSU would also have to be rated at the same level of the service fuses to comply with 133.2, irrespective of what fuse rating it's been lowered to for the output (to my mind, anyway!)
