Changing gas cooker to electric oven with hob

[emmajackt]

Hi, I have an old gas cooker, which I am changing to a electric integrated cooker with induction hob(the hob can be plugged in to a 13 amp socket, but I'm not sure if this would be powerful enough. The power of the hob is 2800W). I have a cooker switch which has its own dedicated 32A fuse. My question is , would my best option be to chase out the wall to behind where the new cooker will be and use a 45A dual cooker outlet plate to connect both the hob and the cooker? I also need a plug socket for the extractor fan. Would I also be able to spur off the cooker switch, or would it be better to spur off a nearby socket? I have included pics of cooker switch and dual cooker outlet that I am thinking of using. Any help would be most appreciated.

Kind regards, Kev.

There is a diversity calculation that can be applied to your oven and hob, which recognises that not all the heating elements will be on at full power the whole time, and will give you the design load.
In most cases, with 'normal' sized ovens and hobs, the existing 32A supply will be more than adequate, but if you gives us the full specs, we can check.
Whether the oven can be wired direct or needs to be fused down depends on the instructions that accompany the oven.
Is the existing supply protected by a 30mA RCD?

Hi Brian, Thank you so much for your quick reply. The supply is protected by a 30mA RCD. The cooker is rated at 2900W and although it is fitted with a 13 amp plug, it says in the instructions that it should be connected to a 13A double pole switched fused spur, so would the one pictured in my first post be ok to wire both the cooker and hob (rated 2800W to?) Also if I replaced my old cooker switch with a new one with a plug socket, would I be able to run my extractor fan from this as well as the cooker/hob, or do you think I should use a separate feed for that?
Thanks again for you help. Kind regards, Kev.
