Hi i have a double oven which is 5.8kw and induction hob which is 7.4kw there currently isnt a cooker circuit in the house but there is 2 spaces in the CU so am I correct in thinking I can put 2x32A breakers in and run 6mm cable to both .
 
I prefer to apply diversity to each separate appliances (in excess of 10A) individually, as opposed combining their total loads, then using formulae.

What do ya think?

Why would you do that then

My understanding of diversity, is that any one electrical cooking appliance, through thermostats etc and switching, would never be able to use its full load, e.g. a simple single electric oven, has a selector switch, to select either main oven or grill, not both together.

Using Table A2 in the OSG for household installations; it shows formulae for diversity & asking for f.l. of connected cooking appliances.

Manufacturers would supply the f.l. figure for their devices. Separate appliances may function differently (as described above).

Further into Table A2, calculating diversity for commercial premises, it makes allowances for more than one appliance, not withstanding the different scenario.

In a simple set up of separate hob & oven, the usage is not comparable, however as is the fashion these days to have more than one oven, combination ovens etc etc, it is not hard to see the usage these appliances could have. Therefore, in such an install, I would calculate diversity separately.

In most cases as Sparksburntout suggested, 6mm would muller most situations.
