If you get an oven with a total rating <3000W there's a fair chance it'll come with a 13A plug and you can use it as a freestanding appliance without much fuss.
Likewise there are induction hobs that are limited to 13A simultaneous load and come with a normal plug and will work ok freestanding.
(I'm assuming you'll be careful finding something solid to stand them on, not blocking ventilation holes, etc)
