[QUOTE="Ardet R, post: 466029, member: 30040"] If you are only using two phases then the simplest thing for the supply company to do would be to change your tariff on the supply that is not for the storage heater to economy 7, however this may not be financially sensible for you if you do not use a significant proportion of your standard power overnight as the calculations would be independent for each supply. With two service heads I think it would not be possible to combine the costs. Changing your supply to a three phase or split phase with three phase meter would allow the E7 costs to be combined but would necessitate terminating one of the MPANs which I can see would not be the supply company's preferred approach as they would then be receiving less income. The installation could be run effectively from a single supply though because you presumably only have electricity service to your house without additional utilities then I would suggest a 100A supply would be the most sensible choice. From a practical perspective this is also very straightforward to implement but would require consultation with your supplier to find out why this was not done in the initial instance, as said above there may be problems with load balancing across phases. However if your house as a whole does not use a large amount of power there would be the possibility to transfer the house supply to the existing E7 supply, if it has a large enough fuse, without supply company input, though this may not go down well with your supplier.
