Best bring my tester and copy of the regs then, I think I mentioned last time I visited that there were a lot of lights on each circuit, they are wired in 1.5mm twin on a ten amp breaker but as I said, there's lots of light. It wouldn't be a great problem to split the circuits but there are no spare ways at the consumer unit

The consumer units are fed by 6mm armoured cable that are rated 63a so there is no issue there.

We'll see when we get there
