Confusion over consumer units

[eddieboy]

Hi folks. My house has Econ.7 therefore I have 2 consumer units. Is it possible to incorporate the heating board into the main board. I don't do any domestic stuff. I've seen dual boards and split boards but I'm cofused as to what the difference is. For example can I buy a dual board and have one side fed from the normal supply and one side fed from the econ 7 side? I have a prepay meter if that makes any difference.

Wylex do a dual tarriff board with 2 100A main switches for your 2 sets of tails but this does mean that you'd have to rcbo all the circuits that needed it which could work out a bit pricey!

Hager do exactly the same, but like Barry say's, works out very expensive
