What is a fixed price tariff and how does it work?

When you’re on a fixed rate tariff, your unit rates and standing charge rate will not change for that duration. So if you enter into a 12 month fixed price tariff, your unit rates and standing charge rate will remain fixed for that duration.

However, that doesn't mean your bills or direct debit will be fixed. If you use more, your bill will be higher. You’ll just be charged the same for every unit of energy you use.

What is a standard variable tariff and how does it work?

A standard variable tariff, or an SVT, is a default energy tariff. The unit prices and standing charge you pay can fluctuate in line with global energy price changes or if Ofgem, the energy regulator, change their price cap. This means that even if you use the same amount of energy, your bills can go up each month.
