If you’re on a variable or standard tariff, you probably won’t have a tariff end date, meaning you can switch supplier at any time.
If you’re on a fixed energy tariff, you’ll find out the end date on a recent energy bill.
You can also give your current energy supplier a quick call and they’ll tell you you’re current tariff ends.
It’s really important we know when your current tariff ends, so that we can switch you at the right time.
