I've got to take another look at it then. I'm getting a similar worktop, but wasn't planning on having utensil draws under it (pan drawers only, with utensil drawers in the island that would be directly behind you when stood at the hob).
I've got a single plug in induction hob currently (as I've got a temporary kitchen setup), and there are 2 big issues with it: 1. the heat source is pretty small compared to the ring size, therefore it can cause the centre of the pan to get much hotter than the surrounds. 2. on the lower settings, it's not an even reduced power. It turns on at what seems to be ~50% power for a few seconds, then off again for a few seconds. It's enough for you to be able to see a pan boil, then stop boiling, then start boiling again etc. I'm just a little concerned about getting a proper hob that ends up doing the same!
