I'd be surprised if the insurance actually required anything much at all, but perhaps best ask them.

Legally in England, (less clear in Wales where as work in a kitchen it may be) such work is not notifiable to anyone in particular unless you are creating a whole new cooker circuit from scratch, you just have to be competent to perform maintenance and replacement tasks, which this sounds like.  Assuming you can follow the makers instructions and use the right size and type of cable, you can just get on with it. An MWC is never a bad idea as it is a record of who where why and what, but its not mandatory. Do check the thing is earthed - its the sort of thing that seems to fail and not get noticed in older set-ups

If it is an induction cooker be aware that some models don't play nice with RCDs and it may need its own RCBO or RCD rather than to share.
