Changing hob

Hi

We have recently had a new fitted kitchen and upon use realised the hob we purchased is not the right one. I wanted to upgrade to a 5 hob one but not sure whether it would be worth the hassle. Would I be able to just switch? I’m not sure if the worktop would need to be cut more as the width on the website seems to be for the whole hob not the deeper part.

I currently have this Bosch one and want to update or this hoover one...
