Supplier fuse query/DNO

[diditrain]

Went to replace a consumer unit today and removed the service fuse. Lady from next door said her electric had gone off and sure enough, when fuse is removed it cuts off both properties. Rang the DNO and they said that it is not a problem. Surely this is unacceptable?

Yes classic with maisonettes, shared fuse. But next door?

Not usual but have seen it a few times. Most we've had was 9 flats/offices off a 200amp three phase head fed direct to all properties with no sub fusing just straight out of the MI pot at each meter. Only one office had access as it was in there basement.
