So Flex is Our Variable Tariff

Our So Flex tariff is our standard variable tariff (SVT). With So Flex, prices can go up or down according to the price cap set by industry regulator Ofgem. 

The Price Cap is the maximum amount a supplier can charge you for energy and is set by Ofgem. At present, the Price Cap is updated every 3 months.

When the cost of wholesale energy or Price Cap increases, so will the amount you pay for a variable tariff. We'll always let you know in advance about any changes in the price of our So Flex tariff. 

You can protect yourself from price increases by signing up for one of our fixed rate tariffs. If you do decide to switch to fixed, the rates and charges you pay will remain the same for the duration of your fixed contract (though how much energy you use will affect your monthly payments).
