Fixed and Flexible tariffs in a nutshell:

• Our fixed tariff locks in the cost of your energy for a fixed term (usually 12 months), so you won't be impacted by any changes in wholesale prices throughout the year.
• Our flexible tariff is a variable tariff, which means the cost of your energy rises and falls every 3 months with wholesale energy prices

Good to know: the price of energy consists of two things: price per unit (pence per kilowatt hour) and standing charge (pence per day). These rates are what will either be 'fixed' or 'flexible'.

With all our tariffs, how much you pay each month will depend on the amount of energy you use. See our FAQ on this for more info.

Fixed tariff pros:

• Price certainty. You know exactly how much you'll pay per unit of gas and electricity each month, which is good news if you like to budget.
• No sudden changes. The cost of your energy will stay the same for the whole term, even if the wholesale price changes.
• Sense of security. You can rest easy knowing you're protected from any significant shifts in the energy market during your fixed period.

Fixed tariff cons:

• If wholesale energy prices fall, the cost of your energy will stay the same, and you won't benefit from any savings.

Flexible tariff pros:

• Potential to save. If the energy price cap falls, you don’t need to do anything, we’ll automatically lower your tariff prices so you start saving.
• Never any exit fees. There are never any exit fees or contract periods with a variable tariff, so you can switch to a different tariff at any time.
• Protected by the energy price cap. This is an accurate reflection of the cost to supply and stops suppliers making a big profit on your energy. (We are the only major supplier with prices consistently below the price cap).

Flexible tariff cons:

• If the cost of energy rises, your bills will also increase. Of course, you'll get plenty of notice, so you can always change tariff.
• It's not as easy to budget.
