A quick guide to fixed, standard variable and deemed tariffs

Here's a quick guide to explain the difference between a fixed, variable and deemed tariff – and help you work out which type of tariff is right for you.

Fixed tariff

With a fixed tariff, your unit rates and daily standing charges stay the same until your tariff ends.

Your bills and Direct Debit payments can still go up or down, depending on how much energy you use.

Standard Variable tariff

If you're on our Standard (Variable) tariff, your unit rates and daily standing charges can go up or down, depending on global wholesale energy prices.

Your prices will never go above the energy regulator Ofgem's price cap.

Deemed Tariff

You're on a Deemed tariff if we supply your energy, but you haven't signed a contract with us (maybe you've just moved in).

Our Deemed tariff prices are the same as our Standard (Variable) tariff prices. This means your unit rates and daily standing charges can go up or down. But your prices will never go above energy regulator Ofgem's price cap.
