Consumer Units in flats with 2 electrical feeds

[GreenElec]

Hi,
I have been asked to replace a fuse box with a new consumer unit.
I visited the flat today and found that it has 2 separate fuse boxes and 2 separate feeds (possibly on different tariffs).
Do I need to fit 2 separate consumer units ?

what do you mean are you saying you have two cutouts, tariff are usually worked out by a dual tariff meter or two seperate meters originating off one supply.
Is it that your cutout is 3 phase with two been metered? and a spare one.

If one fuse box is full of 15anp or 20amp fuses its possible you have off peak board as well as general board, i take it there are storage heaters in the flats.

If they are dual tariff then you can fit a "dual tariff" CU.

Only a couple of manufacturers make them, Crabtree i think, being one.

Thanks for your reply.

Yes, one board has 2 15A fuses and 2 20A fuses, so they must just run the storage heaters then ?

I think I will ignore that board and just replace the main baord with the sockets and lights on it.

You could advise that the storage heater board be changed.

What is the condition of the second off peak board? Is it a wooden backed one with rewireable fuses in it?

Yes, it is exactly that.
