Just wondering what the proper way to do this is. We have a slot in cooker which is being replaced by the built in oven and ceramic hob. It has a feed of 6mm cable from a cooker switch at the moment. The oven can be plugged in via a 13amp plug it seems so do I fit a twin 13amp socket to the 6mm?
Thanks for any help
no
I doubt the hob can run off a 13A socket. Without the power ratings of both appliances and the fuse/MCB rating of the circuit, no one is going to be able to help much.

What is the maximum loading of the hob?
How far away from the oven and hob is the switch for the current cooker?
The hob (with 4 rings?) should be wired directly into the cooker switch.
The oven sounds like it can be plugged into a normal 13A socket, but getting the cable out from behind it might be untidy. Ideally it should be wired into it's own 13A switch box (one of those square boxes with a fuse cover and switch on the front) with fixed wiring.
Wiring the oven into the 30+A supply of the hob, even if the total load can be handled, sounds bodgy.

*Don't* plug the hob into a 13A socket even when wired into the cooker switch; the loading will be well over 13A.Thanks for the response guys and sorry that I didnt give enough information. The oven and hob will be approx 4feet from the oven switch where the 6mm comes from. We havn't got the hob yet so no definate answer to its power consumption. There is no other supply very near to oven housing so it would be nice to get both units on the 6mm tail. All I know is, the power needs of the new units shouldn't be much different from the old cooker with 4 hob rings.

Both need to be within 2m of the switch. If only one is then you will need a second switch to control the other piece of equipment.
In the absence of information I would guess 2kW per hotplate. Some hotplates may be less, some more, it all depends on the design. However, diversity does apply in large amounts to such things.
This is what I would do, assuming that the hob is suitable to be protected by the consumer unit protective device, the hob terminals are suitable and both items of equipment are within 2m of the switch. However, all advice is worth what you pay for it. I have not seen the equipment or the kitchen.
1) run a cable from the cooker outlet to the hob. The outlet should be behind your existing cooker. If there is just a cable from the switch then start there. 2) run a cable from the hob to a fused connection unit with a 13A fuse. This will need to be mounted in a suitable place. It may be that this is above the worktop, with a suitable cord outlet below this. 3) run a suitable cord to the oven.This scheme avoids trying to stuff three large cores into one terminal, which doesn't work very well. Instead there is a maximum of two cores in any terminal.
If the oven is more than 2m from the existing switch then a switch on the fused connection unit is a good way of switching the oven off, otherwise I wouldn't bother with a switch as it is one thing more to keep clean and/or go wrong.
The cables will need to be suitably protected. This depends on the kitchen layout.
If you are outwith Scotland then there are problems of bureaucracy in a kitchen.
What is the rating of the existing protective device?
David: It's a 30 amp device in the CU .Both units will be less than 2 meters from the switch House is about 10 years old so electrics are in quite good order. From the advice given, I will run the hob from the 6mm connector and also from there will feed a 13A fused outlet for the oven. Will use heat resistant cable for the tail to the oven. Hope thats ok Thanks alot for the help :)
That should be fine. If the oven is supposedly itable to be plugged into a 13A socket, then it will almost certainly come with it's own lead.
