Once your fix ends you'll usually be rolled on to your provider's standard variable tariff.

Previously, all suppliers had to roll customers on to standard variable tariffs at the end of their fixed deals. However, new rules now let suppliers move you on to another fixed tariff automatically if you don't switch away when your current fix ends.

If you are rolled on to one of these new fixed tariffs, the rules state they can't have exit fees, can't be more expensive than the provider's standard variable tariff, and must have the same set-up as your previous deal (such as which payment method you use or whether or not you get paper or paperless bills).

Although suppliers are allowed to roll you on to a new fixed tariff, none do right now. This means most customers are still rolled on to standard variable tariffs – so this is what we'll typically use when you compare.
