If you already have an energy contract with us, it's easy to switch to a new deal if:
Around 60 days before your Fixed Energy Plan is due to end, we’ll send you a letter explaining your options.
You can renew online, over the phone, or complete the reply slip included with your renewal letter.
Variable or deemed rates are likely to be higher than fixed term contract rates. You can move to a Fixed Energy Plan at any time. You just need to call us.
Just have an energy bill to hand to make things simple. When you're registered, you'll be able to see your renewal options and enjoy many more benefits from your online account.
Your Fixed Energy Plan won't be auto-renewed. If you haven't made other arrangements at the end of your contract period, you'll be moved onto our Variable Price Plan. This can be more expensive, but it's easy to find a new fixed contract with us, or switch to another supplier. If you want to switch suppliers, you'll need to write to us 30 days before you want to leave and pay any outstanding bills.
