My cooker is spurred off a socket.

If space is an issue, you can use 2.5mm to a single socket or FCU for the purposes of the single oven from the cooker switch.

I would eliminate the double socket from that circuit though.

That's basically what i have now aptsys. The single oven is wired into a fcu off the twin socket. I could swap the fcu for a oven connection unit leaving the oven as is. Run a single socket off the new connection unit. Wire the new hob into the new cooker switch & socket combo which is replacing the twin socket?
