Ok, but it is not really.
It could signify inexperience or a lack of understanding.
For example, if any of them install as one of the circuits a 32A, 4mm² OR 6mm² cable circuit for the hob then the two ovens could without question also be supplied from this circuit - and be future-proof.
If they are not keen on this then another TWO circuits for the ovens seems like overkill to me.

The maximum load of the old range was 16,485W while the three new appliances combined are 13,650W so, as I never had any issues before, I'm planning on sticking with the current 4mm circuit wiring and 32A fuse in the consumer unit.
