That doesn't always follow. They may well work FSV of "work".

Both are on a 13A plug, so the double one has to be less than half that
rating.

An oven on a 13A plug these days is easy since they are fantastically
well insulated and recirculate the hot air.

A hob is much more of a challenge since it is putting heat into a pan
and the success or otherwise depends to on the base of the pan and the
peak power that the hob can deliver. 13A only gives you a total of 3kW
to play with which might be enough to simmer something on every ring but
you are not going to be able to stir fry at the same time!
