What's the difference between a fixed energy tariff and a variable energy tariff?

A fixed energy tariff isn't changed by the energy price cap, and a variable tariff can change with the Ofgem Energy Price Cap.

You'll decide on your energy tariff when you sign up with a new energy provider, and when you sign up for a One Utility Bill package.

You'll always find out at least 30 days before any price changes to your One Utility Bill package.

A fixed energy tariff means that your price won't change if energy prices go up and down with the Ofgem Energy Price Cap, which means predictable bills. 

A variable tariff usually changes with the Ofgem Energy Price Cap. This can mean prices go up or down throughout your contract.
