We are having the kitchen extension connected soon and the consumer unit needs to be replaced as there isn't a spare for the new electric cooker circuit. The electrician said we would need a 12 way but when he tried to get one locally they only had 10 way so he has suggested two 6 way consumer units. Is this okay or should I insist on a 12 way?
Two consumer units, okay or not?

Thanks for the reply.
I think the local suppliers here in Inverness don't hold as much stock as in the rest of the UK.

Each consumer unit would be supplying an installation and each would have a main switch so no problem and no up-front separate main switch required.

Thanks GaryMo. I just needed reassurance.
I'd still prefer a single CU where possible though I have 2 x 10 way dual RCD CU's.
537.1.4?
Is it really 2 different installations because there are 2 CU's side by side?
I'm going off memory as I don't have a copy of BS7671 with me but check definitions for an electrical installation.
It also happens to be the same guidance that the ECA give.

Thatll be a switch in each board for each installation.
537.1.4
A main linked switch or linked circuit - breaker shall be provided as near as practicable to the origin of every installation as a means of switching the supply on load and as a means of isolation. . .
Definition of Installation:
Electrical installation (abbr: Installation). An assembly of associated electrical equipment having co-ordinated characteristics to fulfil specific purposes.
Hmm pretty vague definition right enough.
I guess it's a grey area but it makes sense to me to have a single point of isolation for a typical dwelling.

Looks like the ex-Pats have their fingers on the button - or should it be the main switch?
It does seem a little vague, although it reads to me that there should be one main switch, it isnt really a 'main' switch if there is more than one of them.
If required I always fit one main switch.

On this install it sounds like he would have two 6-way CUs side by side. Not one in the hall and one in the kitchen.
I would expect there to be a 30mA at the front end of each of these CUs with a separate main switch to isolate the whole house if needed.
As this is a domestic "unskilled" situation I would say a single main switch is mandatory.

There is nothing stopping the installer siting the main switch in one of the consumer units and taking tails out of the bottom of the switch into the next board.
