The kitchen is about 12 feet square. There are 7 double sockets, 5 above the worktops, 2 low down on an empty wall. There's also a FCU to feed the boiler.
Just the usual kitchen appliances, microwave, toaster, kettle and dishwasher (washing machine and td in utility room on a separate circuit)
So nothing unusual.
The kitchen at it's closest point is about 25 feet from the CU, so assuming the 6mm goes all the way to the kitchen that gives a rough indication of it's length.
Ring continuity in the kitchen tests okay (and importantly the same) measured at every socket. Every socket was tested to confirm it really was a ring, not a radial branch circuit in 2.5 I've not tested r1+r2 at the cu end yet, but that will give an indication of the length of 6mm involved.
The dual fuel cooker is on it's own circuit, and this "lolipop" circuit feeds only the kitchen sockets.
At least now the gas and water are bonded, so as soon as I've completed the other modifications (utility and new shower room) I'll complete the CU change.
Customer has not asked me to do anything other than CU change and these few modifications, I merely posed the original question as I had not encountered such a circuit before.
So I have convinced myself that it's fine to proceed with the CU change, even if I never find the junction from the 6mm to the ring final, which more than likely is under a downstairs floorboard, or behind a wall. I doubt it's plastered in as most of this house is dry lined with plasterboard.
