2 Consumer Units or 1?

[qamikazi123]

Hi All
I need some advice please.
I am getting my house rewired and have asked for each room to be rewired on a separate circuit so if 1 room has any problems and trips it does not affect the lighting/sockets in any other room.
its a 5 bedroom house and kitchen diner and living room (total 7 rooms). I want the landing to be on a separate circuit too.
Overall i need approx 24 circuits to the consumer unit. My electrician has advised me to have 2 consumer units which consists on 1 consumer unit for the ground floor and separate consumer unit for the upstairs.

I have seen some Hager Duplex consumer units that are 28 way and wondering if it would be better to get one of these which will cover what i need with a few extra for future use or should i get 2 consumer units as suggested by the electrician?.

Here is the CU i was thinking of...
Hager VML11414 Duplex 14+14 Way Stacked Consumer Unit

Would be grateful for any advice/suggestions

We did a house last year which had 27 circuits. This was made up of a consumer unit on each floor rather than a stacked one on ground floor. Was easier to wire, less cables at board and makes more sense for the amount of circuits

Its your house @qamikazi123 and can spend your money as you see fit. My 4 bed house, as hundreds of thousands across the country, has one dual rcd Cu, with the kitchen on one of the RFC’s, and the CH. Can’t see much problems presenting themselves. If I’d wired my property, I might of considered RCBO’s CU, separate circuits for kitchen or CH, but not something I’m gonna loose sleep over.

Think your overthinking things IMO.

If that what the Op wants then who are we to argue against him, he obviously has his reasons, perhaps he is renting rooms out, in which case might I suggest you install RCBO's instead of RCD's and MCB's, it does seem quite elaborate if it is just a family home though

when I get round to re wiring my house, it will be a similar arrangement to you have suggested.
1 socket circuit for each room
1 circuit for lighting on each floor, incorporating 1 emergency fitting in each room
1 circuit for kitchen sockets
1 circuit for bult in kitchen appliences
1 circuit for the oven
then the others, outside lighting, outside sockets, boiler, etc.


I will probably have a 6 way board next to the meter
feeding a board on each of 3 floors and a further one in the outside workshop.

yes it is overkill
but that is the way I want it done.
stick to your guns, you are the customer.

your electrician should be thinking of ways to make it happen in the way you want it done. (within reason and regulations)
an emergency light fitting by each of the distribution boards is one of the most useful thing ever if you ever need it.

an emergency light fitting by each of the distribution boards is one of the most useful thing ever if you ever need it.

But only if it is properly maintained, otherwise it'll be pot luck whether it works, doesn't work or cuts out at just th ewrong moment.

if 1 room has any problems and trips it does not affect the lighting/sockets in any other room.

As previously said you wont achieve that with a dual or triple RCD board it will have to be individual circuit RCBO's all the way . ££££'s!

Very expensive installation, the time and materials.

But why would anyone do this ?
