Electric Hob and separate Oven - advise please.

I have just bought a flat with an electric oven under a worktop and an electric 4 plate hob sitting into the worktop. I want to replace the hob.

I have taken the oven out and it appears the oven (electric) and the hob have both been wired into the outlet plate on the wall (turned on and off by a cooker switch) above the worktop and wired back to the fuse box in 6mm cable and a 32a trip switch . Am I correct in saying the oven should be wired into its own socket and fused? and the electric hob only be wired into the outlet plate?

Can a feed come off the outlet plate to feed the oven in separate socket with a fused connection?, or should the oven be fed of the 2.5mm kitchen ring main and be wired in its own socket and fused?

Thanks in advance

It depends on the total power requirements for the oven and the hob. Normally both the oven and the hob can be powered by the same circuit, but it does depend.
The manufacturer may require a fuse of less than 32A to be used. Check the installation requirements of both.
If you had bought a COOKER (ie an oven and a hob all mounted in one box) then you wouldnt think twice about hooking the one thing to one single circuit.

You would be best replacing the outlet plate with a dual one like this, as the existing one probably won't allow three 6mm² conductors to be terminated.
The manufacturer of a fixed appliance can stipulate how it is fed and fuse/MCB/RCBO sizes. However convention is a 32A feed can be used for both oven and hob. With some ovens under 13A they are normally either plugged in or come from a fused connection unit but there is no unit to do this at 16A so ovens designed for Europe often have to be connected to the 32A supply.

For oven under a hob the stand alone cooker is often a better option. 1) some hobs state a distance from over which is hard to comply with, and can be affected with heat from oven. 2) stand alone cookers can run oven elements together, where ovens need to limit their total power to 13/16 amp so have to time share between two elements.
Thanks for replies, the dual outlet plate looks like a good option. From one of the outlets is it recommended that it feeds a socket, so that the oven can be plugged in with a 13A fuse?

1) Do you want to have the oven on a 13A fuse? If so, why?

2) Is it suitable for being on a 13A fuse?
