Just checked in my new-ish flat where I have an electric oven only (gas hob). It's a 13A square pin standard wall socket, but does have a dedicated breaker, so it is indeed not on the ring main for the other wall sockets. It has a 32A MCB in the consumer unit (same as on the two main rings). Not sure if it's ring or radial without removing the socket.
