Can I connect this hob to the socket ring final via a fused spur, or does it need a bigger supply?

Not off of a 2.5mm supply cable its not...
32 amp radial min 4.0mm i dont bother with 4.0 just use 6.0mm
A reasonable rule of thumb is 4 amps per kilowatt, so 3kW is 12A.There's a 6mm cable to the old cooker. Under the hob i'm going to have a 3KW single oven. Can the 6mm feed both?
Or do i need to run another?

Apply diversity again and you get 10A + (30% of 2) = 10.6A
Added to the hob you get 10.6 + 14 = 24.6A which is fine with 6mm2, as long as the breaker is appropriately rated.
Please note I don’t do this for a living, but Dunning-Kruger effect aside:Can I have the hob off the 6mm and the oven off the socket ring?......
Ok brill thanks I will do that. Thanks your your help chapsPlease note I don’t do this for a living, but Dunning-Kruger effect aside:
I’d say it’s technically ok to spur a 10.6A load from a ring spur (you have to add 5A if the oven isolator has a socket, mind), but not best practice. You don’t want the oven to suck 1/3 of the ring capacity, nor to take out a load of sockets if it nuisance-trips or needs maintenance.
I’d stick both on the 6mm.
The old method of wiring lighting circuits with millions of junction boxes hidden away is pants.
So my pea brain can understand this, ahead of fiddling on Friday to put in new switches runs to somewhere sensible, this is the feed to two wall lights, each with a separate cable.
If the two cables on the left are feeds to the lights, is right/bottom the feed and right/top the switch cable?
