Replacing freestanding gas oven with separate hob/cooker

So you will have a 2.5mm cable for a spur on a 40a circuit

Annoyingly yes. I judge from the question that this will need upgrading to a 6mm2 ?

Also the double socket will not be rated for 40a, you may have to use a switched fused spur to feed the socket, so 6mm to sfcu then 2.5mm to double socket

No. A FCU can only draw 13 a due to the fuse so 2.5, 1.5, or even 1.0 mm is theoretically OK.

The double socket will never draw 40a as the two plug fuses add up to 26a. Use 2.5mm2 cable and no FCU.

Yes, perfectly alright as long as sufficient for fault protection - which it will be.

No. A FCU can only draw 13

An FCU will not draw any current, (*) but will pass a current to something else that does draw current.

With a fuse rated at 13 Amp the FCU will pass significantly more than 13 Amp before its fuse ruptures.

(*) if there is an indicator lamp in the FCU this will draw a small amount of current
