OK, is it a hob, oven or both? An oven can quite often only require a 13a plug. As footlaps says, it will depend on the current rating. An oven of 3kw or less will run happily on a 13a plug (3kw = 13a approx.).
An electric hob with or without and oven will carry much more current and require a bigger cable – usually a 6mm one – and will have a big outlet behind it.
If it’s an electric oven only, then it will probably either be on the ring (2 cables in the socket) or a spur (1 cable in the socket). It may or may not have a fused spur located for isolation purposes – probably not though.
Any problems, drop me a photo (email in profile) and I’ll try and remotely resolve it for you.
