The
only thing that's really changing is the new hob is an induction one
rather than a solid hot plate. I hear can they require a bit more oomph.

Sadly you said the words "induction hob".

It is likely that your present supply cable is not suitable to supply
the new power requirements and you will need a new cable from the
consumer unit to the kitchen. Only someone with good knowledge can
advise you, after seeing what you already have, and this would be an
electrician.

I thought (read in a Bosch/AEG glossy) that induction hobs were more
energy efficient? I assumed that would mean their power requirements
would be lower. Why am I wrong?
