Electrical Circuit help

[NorthernRunner]

Hi all. I'm fitting a new kitchen and looking for some help with electrical circuit alterations considering loading increase for some new appliances. Kitchen and other areas of ground floor already has a 32A ring main for sockets and the consumer unit has a spare way available if needed. Existing ring will need to be used for standard appliances (kettle, fridge/freezer, toaster, microwave, dishwasher, etc - and boiling tap).

The main loading increase is to add 2 side by side single electric ovens (2400W with 13A cord/plugs fitted) as well as a hob on a separate island with built in extractor (7400W). I'm sure that the spare way will need to be utilised to supply the hob but unsure on what to do about the ovens as these might overload the existing ring.

Any advice appreciated.

Is there not a standard "cooker circuit" in the kitchen?

Such a circuit will be adequate for all he cooking appliances you mention.

No - the old single oil fired cooker (now removed) was plugged into the 32A ring main

New 32A circuit with appropriate connections for the two ovens and the hob.
Existing ring for everything else.

The appendix of BS 7671 says non protable appliances over 2 kW should be on a dedicated circuit, so oven, hob, dish washer, washing machine and drier although latter really are not kitchen items.

Today with heat pump tumble driers they don't use 2 kW and other than tumble drier they do not use high power for long enough to matter, so only over 3 kW does it need a dedicated circuit, so hob, oven, immersion heater, shower, EV charging point need dedicated circuits but not much else.

Your boiling water tap may well need a dedicated circuit.
