Fixed Energy Tariff

What is a fixed rate tariff?

A fixed tariff means that both your unit rates and your Membership fee (standing charge) won’t change for the whole of your contract. So you’re protected from price rises. All our tariffs include 100% renewable electricity and 100% carbon offset gas, and we provide dual fuel fixed price tariffs or electricity only.

How we calculate our fixed rate tariffs

For fixed price energy tariffs, we calculate your unit rates on the current cost of electricity and gas for the whole of the fixed term period. When you switch to us, we purchase enough energy to cover our forecast of what you’ll be using over the whole period.


Peace of mind

So if you switch to a 12 month fixed tariff, we “lock in” the cost of your energy for a full year. Your unit rates won’t change during that time.

As we’re buying energy for you up front, we charge an exit fee on this tariff if you switch away or change tariff early.

at the end of the fixed term

What will happen when my contract ends?

Near the end of your contract period, we’ll be in touch to let you know what your options are and what our current best tariff is.

Our tariffs are designed around you.

Variable tariff

Best for flexibility

Choose a variable tariff if you want freedom and flexibility. No fixed contract or exit fees — you're in control. We'll protect your unit rates for two months. After that, your unit rates can change. We'll always give you at least 14 days notice of an increase.

  • No exit fees
  • No fixed contracts
  • Price protection for two months
