Don't quote me on it but splitting tariffs might be something to look at and it has worked well for us. The reason why is you don't pay tons for gas over the summer which is lumped in with the electric usage. This is what I pay:
So energy standard variable (gas)
Unit rate - 7.32p/kWh
Standing charge - 27.21 p/day
DD = £20pm, £40pm over the winter (excl price cap change)
EON Next standard variable (electricity)
Unit rate = 28.02p/kWh
Standing charge = 42.24 p/day
DD = £59pm, shouldn't really change much over the winter (except for the price cap change)
total = £80pm at the moment, I'm reckoning and hoping that it will go to something less than £200pm with the price cap changes and increase in winter usage etc.
I'd suggest anyone with a smart meter to also try the app Loop Energy, it tells you exactly day by day how much you're using and how much each day is costing you. If you have solar panels you can also add these in and it simulates the reduction in your spend. We spend about £1-2 on electricity daily, one boil of the kettle makes up about 20p of that!
