It's a 2.5 radial on a 20 amp breaker. It's tripped a couple of times when there were lots of appliances on at the same time in the kitchen, so I thought I'd ask him about upgrading the circuit.

Can he not just put a 2.5 cable onto the last socket and wire it back to the new 32A breaker? Make a ring out of the kitchen circuit. That way there may be less work that needs doing.
