At least nobody has written back "YOU CAN'T DO THAT, ITS A TERRIBLE IDEA" so I feel partly re-assured

Is the hob wired as single phase hobs of each of the three phases, or they actually three phase elements? If so, they will be star connected and there will be no (or neglible) neutal current.
even if not, you can apply diversity to the hob, so 7.2kw is about 2.5kw per phase (roughly) so about 10 A per phase. But of course not all phases can peak at the same time, so you still find your neutral current is preety low. 2.5 is roughly 27A (with no correction factors,) so you are well within
So
A. You wont oveload the cable
B. Cant say if its 'legal' against your regs, but would almost certainly be against ours because of the borrowed neutral
