Set up a Direct Debit in your online account. If you're not set up yet, it only takes two minutes to register – have a bill to hand for easy registration.
Once you've done this, you'll need:
You can update your bank details at any time, but you can't change the amount.
If your business needs consent or signatures from two or more people, you'll need to complete a Direct Debit mandate form (PDF, 143kb) and pop it in the post to us.
You'll pay the same amount on the same day every month. If your agreed payment date falls at the weekend or on a bank holiday, we'll collect payment on the next working day. The amount you pay is based on your recent energy usage and any outstanding balance. We review your payments regularly to check they're right for the amount of energy you're using.
You'll pay for what you use when you use it every month or quarterly as shown on your bill. You may pay less in the summer and more in the winter.
The amount you pay is based on your recent energy usage plus any outstanding balance spread over 12 months. For example:
Annual energy usage = £1200
Outstanding balance = £600
Total = £1800
Divided by 12 = monthly payments of £150
If we don't have an up-to-date meter reading, we base the amount on an estimate of your energy use.
Avoid estimated bills by giving us a meter reading.
If it's summer and you're using less energy, you might find you're in credit. Your payments will balance out when you use more energy over the winter.
We review your payments regularly. If you're paying too much or too little, we'll recommend a change so your payments are right for the energy you're using.
We'll let you know before we make any changes as part of the Direct Debit Guarantee.
