Why choose First Utility?

As the UK’s leading independent gas and electricity supplier, we go above and beyond when it comes to providing you with cheap tariffs and competing with the bigger energy companies.

We’ve introduced our Price Promise, so you know that when you sign up your average annual price will be less than it would be if you opted for a standard tariff from one of the ‘big six’. We’re also lobbying both the Government and Ofgem in order to change regulations that create an unfair market and penalise consumers. We’re passionate about what we do and we hope you are too.

*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 tariffs (or any replacement tariffs as that company's Standard Tariff): British Gas - Clear and Simple, E.ON - Energy Plan, Scottish Power - Standard, npower - Standard no standing charge, 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.
