I rewired a house in 1983 and certainly there was no such wiring, the
recommendation at the time was to to have separate ring mains and
lighting circuits upstairs and down. I have seen instances where
people have wired spurs off an upstairs ring into a room below which
has safety implications. It can be a common mistake in houses which
have solid floors downstairs as it is possible to have two ring mains
running in the ceiling space one providing drop feeds to the
downstairs and the other for the upstairs, maybe something like that
has occurred at your friends house?


My house has left/right ring mains rather than up/down. Some rooms, like
the hall, have both ring mains. It's often quite useful, easier to run
an extension lead from rooms on the same floor than it is down the stairs.

Is this against the regs/ a mistake?

It did confuse me a couple of days ago, but more that I switched off
something I didn't mean to, rather than I mistakenly left a socket live.
I always physically check a socket isn't live before working on it.


I have something similar here but with 6 ring mains:

Kitchen & Utility room

Front room and the bedroom above it and the office above the kitchen and
the landing sockets

Dining room and the bedroom above it

Lounge and the Master bedroom above it and hall sockets

Loft ring main

Garage sockets and all outside sockets
