All the places I've lived in (UK) used a 32A 240V radial spur with a dedicated breaker with the appliance hardwired, or a regular wall socket on the kitchen ring main, 13A 240V, with a shared breaker (lower power portable appliance). Never seen 2-phase wiring for domestic use.

I thought, but I could be wrong, that UK cookers use a radial spur with a dedicated breaker, and that sometimes those breakers also include a standard regular wall socket, but this socket (and the cooker) are still on their own radial spur. The cooker should never be connected to a normal kitchen ring main.

Why can’t ovens of less than 3 kW be connected to a ring final circuit via a suitable connection point such as a socket-outlet or fused connection unit? > Appendix 15 is intended to give guidance only. Such connection is not prohibited, provided that no part of the ring final circuit will be overloaded as a result. > Regulation number(s) > 433.1.5 So, not forbidden, but if you have new wiring the electrician is going to give the cooker its own circuit.

  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.
