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?

Are you getting this costing info from the In Home Display (IHD)
We will need to fully set up your smart meters and your OVO account with your tariff and new meter details before the info on the IHD is exact. This might also be the issue with any costs displayed on My OVO so soon after the meter fitting date. Drop the Care team a message via Facebook, Twitter or email (firstname.lastname@example.org) to get this checked.
