The price cap means the price per unit of energy you pay and your daily standing charge can't go above the level set by Ofgem. It’s not a cap on your energy bill, which will rise or fall depending with how much energy you use. The cap is updated by Ofgem twice a year, depending on how the cost of supplying energy to your home changes.
Which tariffs are affected?
The tariffs affected by the price cap were:
- Standard Variable
- Cap Tracker September 2020
- Cap Tracker December 2020
- Cap Tracker December 2020 v2
But if you were affected, you'll have received a letter around the end of August about how the 1 October 2019 price change affects you. You’ll also see your new prices on your bill or statement.
If you were on any of our other fixed tariffs when the prices changed, you won’t be affected until that tariff ends.

Electricity bill costs
Gas bill costs
These breakdowns are based on an estimate of costs at Ofgem’s annual average consumption - 3,100 kWh for standard rate electricity and 12,000 kWh for mains gas, and also market average margin returns as per Ofgem’s methodology of calculating the default tariff price cap.
