We have just moved into a house and i have been looking at the electrics,and have found the Kichen sockets to be on there own ring which is ok, but the rest of the sockets ie the down stairs and upstairs are all on the same ring there is a total of twelve sockets is this ok or should they be on there own.
Basic answer is yes it's OK. House age is of course an issue my house 1979 only had one ring main. Now normal to have a ring on each floor. 100 sq meters floor area is the limit. I can't see there being any problem.
