My problem is that I found two sockets with only one set of wires, all
the others had 2 sets. I thought this would be classed as a radial
circuit but then discovered that the MCB on the consumer unit (rated
20 amps) had two wires connected to it.

It's a radial, one T&E from the CU goes to one socket, the other T&E
from the CU goes to the other socket. A radial can be branched
anywhere, even at the CU. A 20 amp MCB is correct for this type of
circuit.
