We’ll get in touch with you by email or by letter before to let you know any changes to what you will be paying and what your options are. It’s up to you what you choose to do next.

If you’re on our So Flex variable tariff, you can:

Stay on a variable tariff - this will mean that the price you pay for your energy will increase and decrease in line with the price of wholesale energy. We’ll always let you know before any increases in what you’ll be paying. Variable tariffs never go higher than the price cap set by Ofgem.

Switch to a fixed rate tariff - by doing this, you can fix your unit rates and standing charges for peace of mind so you don't have to worry about changes to the variable tariff. This avoids the uncertainty of being on a variable tariff.


If you’re on one of our fixed-rate tariffs, you can:

Roll onto a variable tariff - if you don’t renew or change supplier when your contract ends, you will be put on our So Flex variable tariff (this will happen automatically, so you won’t need to get in touch). As outlined above, the price you pay will move in line with the price of wholesale energy, and we’ll always let you know in advance about any increases. Variable tariffs never go higher than the price cap set by Ofgem.

Renew onto a fixed tariff - if you’re coming to the end of your contract, you can renew to a fixed tariff and lock in the unit rate and standing charge for peace of mind. This avoids the uncertainty of being on a variable tariff.

Our So Flex tariff rates may be higher or lower than the rates of your fixed contract. If you do decide to stay on or move onto our So Flex tariff, your monthly will need to be adjusted to avoid going into debt. You can adjust your direct debit payments by logging into your online account here.
