I had new smart meters fitted yesterday afternoon. Rather shocked to see my costs at over £5 for half a day by the time I went to bed!!! Most of it was Gas usage (>£3) and it wasn't even a cold day. According to my Nest thermostat, the boiler was only running approx 1.5 hours since the meter was fitted. How can 1.5 hrs heating equate to £3 usage ? Boiler (not combi) is rated 24 kW max and tariff shows 4p/kW (which is wrong - should be 2.68p). My basic maths suggests this should be 1.5 hrs * 24 kW * £ 0.04 = £ 1.44 + 27p standing charge. That assumes boiler runs at full tilt the whole time which is not correct as I hear it modulate down after a few minutes.
This doesn't seem right to me. Even if/when the tariff is corrected it seems too high.
How can I get the tariff set to the one I'm actually signed up to? How likely is it I've got a duff meter that is reading too high on gas?
