*Average annual bill based on average usage of 3,200 kWh of electricity and 13,500 kWh of gas on a national basis.

** The price promise relates to the following competitor dual fuel tariffs (or any replacement tariffs as that company's Standard Tariff): British Gas - Standard, E.ON - Energy Plan, Scottish Power - Standard, npower - Standard, EDF - Standard (Variable), SSE - Standard Energy, in each case as offered directly by the relevant company with a Direct Debit payment method and paperless billing.
On a weekly basis we will compare the prices of this tariff against those listed above. The calculation will be based on average usage of 3,200kWh of electricity and 13,500kWh of gas on a national basis. If the cheapest average bill value based on average usage on a national basis of any of these tariffs falls below ours, then we will reduce our tariff to be lower than that average bill value within 60 days of your next Billing Cycle. These tariff comparisons will be listed on our website. National means “The Non-Exclusive Appointed Area” that shall mean any geographical area in mainland Great Britain.
