Credit/Debit card

Please call 0800 012 4510 or
033 0088 1619 (both option 3). You will need your account number and your card details. Please note credit cards are subject to a 2.5% surcharge. There is no surcharge on debit cards. Unfortunately we cannot accept American Express for payments.

Other ways to pay

Cash - You can pay with cash at your bank or building society using the Giro slip on your bill, or at the post office by using the barcode printed at the top of the last page.

Cheque - Fill in the Giro slip on your bill and along with a cheque payable to 'Green Star Energy' take them to your bank or building society. Alternatively you can post them to Green Star Payments, Elder House 3rd Floor, 586-592 Elder Gate, Central Milton Keynes, MK9 1LR.

BACS - For BACS payments, please use Payee: Green Star Energy LTD, Sort Code : 40-33-33 Account number: 72409364 and your Green Star Account Number as the reference, this can be found on your bill. 

Direct Debit - Paying by Direct Debit saves you £34 per fuel per year. For more information call us on 0800 012 4510.

Post Office - We now offer Post Office payment cards, so you can make regular payments at your local post office. Please contact us if you would like us to have one posted to you.

Pay as you Go - Sometimes the easiest way to manage your payments is to have a prepay meter fitted. Please contact us if you would like to arrange for us to fit a prepay meter. There will be no charge if we undertake this work at your request, although you will need to move to one of our prepay tariffs.

Understanding your bill


Why is my bill so high?

If your bill is higher than you expected, it may be due to one of these reasons:

  • Is it an estimated bill? If you haven't given us a meter reading recently, we may have estimated your bill. We will adjust your bill if you provide us with a meter reading within 14 days.
  • Are there more days in this bill period? It may have been a longer month or there may have a bigger gap between meter readings.
  • Have you got a balance brought forward? If you didn't pay your bill in full last time, the remaining amount will show on this bill
  • Have you recently changed tariff? If the tariff you were on has ended or you've changed tariff your bills are likely to change. We'll contact you when your tariff is coming to an end to discuss your options
  • Has there been a price increase during the time of the bill? If energy prices have gone up this may have affected your charges
  • Are you using more energy? If you have more people at home, have bought some extra appliances or if it's got colder, you may simply be using more gas and/or electricity
  • Have you had your appliances checked or serviced recently? An old inefficient appliance will use more energy, and may need to be replaced
  • Was your recent meter reading wrong? If we read your meter or you sent us a meter reading, there's a slight chance it may have been wrong. Submit another meter reading online.
