If you're in a three bedroom semi in a cold part of the country that would be even better. We have recently moved house and we appear to be averaging around £110 a month, which I'm guessing will be higher in the middle of winter. We have four storage heaters switched on low, plus the hot water and the normal daily uses. We're on Scottish Hydro's Total Heating Total Control.
My starting point is that our old 2 bed terrace in England had gas central heating and our total monthly bill for gas and electric was £55 a month.
A related question, has anyone switched away from a THTC tariff or replaced their electric heating altogether, either with new storage heaters or a new LPG central heating system. Did this save you money?
TIA
