Replacing cooker with hob and oven

[arabbadot]

I am replacing an old cooker with a separate hob and oven. The existing wiring is from an outlet with a separate oven switch. Both new items are rated for 13 amp plugs. Can I simply wire from the outlet to the oven and from there to the hob with 6mm cable. My supplier says yes but just checking. Any help would be appreciated

Whether that's ok will depend on the size of the cooker fuse/circuit breaker, and how the existing cable is run.
A simpler way would be to avoid using 6mm cable at all.
I guess you have a cooker switch above worktop, and an outlet connection below worktop level?
Either replace the outlet connector with a double socket, or two fused spurs.
What size is your existing cooker fuse/breaker?

Yes that is the layout.i had not thought of substituting the outlet with two sockets served by the one switch. There is a 30 amp fuse in that circuit.
Thank you very much for your suggestion.
