I know it is not recommended, but I put my hob in with a cooker
flexible,
that was twenty five years ago and it is still ok. After all if it
is
ok
for a cooker, why not a hob?

I thought it was allowed

The ultimate word is with the manufacturer's instructions: if it says a
flexible is OK, then it is OK,

Flexible on a hob is now not OK.

Would you mind elaborating (like: who says so, in what document)?

And do the manufacturer's instructions no longer carry any weight?
