You really need to provide more information than that.

Whats the rating of the cooker and the oven. Whats the rating of the current protective device. What are the oven and hob required to be fused at?

ceramic hob is 5800 watts and double oven is 4080watts i have 6mm from cu to switch is that any good ?

Do you know how the 6mm cable is routed?

I'd say that 6mm cable is a bit marginal for that load, but there is some diversity you can apply to kitchen circuits perhaps a spark can advise on that...

cable is run from kitchen to garage thru walls i think

Excellent, gas is the better choice.

a double oven of 4080 watts will run in a 20 amp MCB. You can use the 6mm cable, although it is rated at 40 amps, it is ok to overspec cable.

The gas hob will plug in, or wire to an FCU.

thank very much the existing hob is 13 amp plug igniter and the rcd is 16 amp do i need to change it

Heh if gas is an option, then its a no brainer.

Electric hubs are bloody awful things.
