* 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. This variable tariff comes with our Price Promise which means that it is cheaper than the Big Six standard tariffs at typical use**. If the national bill value based on an average user, of any of these tariffs falls below ours, then we will reduce our prices to be the lowest 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.

**Average annual bill based on a national average usage of 3,100 kWh of electricity and 12,500 kWh of gas.
