ring main

So I suggest you do a simple continuity test. This isn't a quick job.

You will need a long lead and a bell/buzzer or an ohm meter.

TURN ALL POWER OFF

Disconnect the ring conductors at the consumer unit.

Connect one end of the long lead to the live conductor. At the other end of the long lead you need your buzzer/whatever.

Go to the nearest socket to the consumer unit and connect the other side of the buzzer to the live terminal of the socket. you should get continuity. If you dont, it may be on the other half of the ring, so move the long lead to the other live conductor at the consumer unit.

Once you have established continuity to the first socket you can move round the other sockets until you loose continuity.

Then test using the othe leg of the ring to test continuity for the other half.

Using an ohm meter is best as you should see the resistance of the ring conductors increase as you get further away from the board.
Draw a picture of every room and each socket and number them or you can loose track.

At the end of the process you should have a reasonable map of the ring and a good clue as to the location of the problem.

I mean't have you just moved in, in regards you are not aware of any work that has been done in the place recently.

Do you have continuity on the CPCs?

Are you sure the two cables you have at the CU are both part of the same ring circuit?

there is another ring main for upstairs.
do you think that maybe the legs have been muddled up?

Test it and see.
