1. A default tariff is the rate paid for gas and electricity if you don’t choose a tariff for yourself. 2. You will be put on a default tariff when: - Your fixed rate tariff ends. - You move home. - You are moved to a new supplier when your old supplier goes bust. 3. You are probably on a default tariff if you haven’t switched suppliers in the last year, or you’ve never checked what tariff you’re on.
