Your Direct Debit Options

When it comes to setting up your Direct Debit payments, you can choose from fixed or variable Direct Debit payment methods.

Flat Monthly Direct Debit
With Flat Monthly Direct Debit, we collect the same set amount from your account each month, on an agreed upon date. The amount we collect is based on the amount of energy we think you’ll use across the year and any outstanding balance, divided into regular payments.  If you find you have a debit (DR) balance that keeps growing, you should consider contacting us so that we can raise your Direct Debit payment to catch up


Variable Monthly Direct Debit
With Variable Monthly Direct Debit, we collect the amount you owe us for your energy usage each month, 14 days after your bill is issued. This means that the amount you pay each time may change depending on your usage, so if you’re submitting regular readings, you won’t be paying more or less than the energy you use.

Changes to your Direct Debit Amount

We regularly review your Direct Debit to make sure you’re not paying too much or too little for the energy you’re using, based on your annual consumption. That way we make sure that when your Green Star Energy contract ends, you’ve paid for all the energy you’ve used. 

If you’ve recently received a notification suggesting a change to your Direct Debit payments and would like to discuss this, please call one of our friendly advisors on 0333 023 0142 or email us at [email protected].

How our Fixed Direct Debit Works

1. We work out how much energy you're likely to use
First of all, we will use your past bill or statement to estimate how much you’re likely to use in the coming year, based on how much energy you used in the last twelve months.


2. We set your monthly payment amount
We then estimate what you'll have to pay and divide it into even monthly payments.


3. We adjust your payments
We want to make sure you're just paying for the energy you use. So every few months we'll conduct a review of your account to make sure you're doing just that.


REMEMBER: Please contact us if you have a debit (DR) balance that keeps growing, so that we can raise your Direct Debit payments to catch up.


If your account ends up in credit after paying your Direct Debit, you can claim this back online at any time. Find out how to claim a rebate here.

Your Direct Debit Questions Answered


How are my Direct Debit payments calculated?

We know that you are going to be using more energy in the winter and less in the summer. So rather than sending you expensive bills in the colder months, a Flat Direct Debit will spread this cost out instead. 

How much you pay is reviewed every few months to ensure you’re being charged the right amount. 

You could also set up a Variable Direct Debit with Green Star Energy. This would enable you to pay the exact amount of your bill each month, direct from your bank account.

To ensure you aren’t paying too much, please remember to submit regular meter readings.

When do you review my payments?

We will periodically review your payments throughout the year to check that you’re paying the right amount. If we find that you’re either paying too much or too little, we will make an adjustment to your Direct Debit amount to keep you on track. We will never make these changes without informing you first.


Once a year we will conduct an ‘annual review’, at which point we will look at how much fuel you used in the previous year, and how much the same usage will cost you over the next 12 months. If you have used either over or under the amount you’ve paid for, we will factor this into the Direct Debit amount to make sure you’re not building up debt with us.  


If you find that your energy account has a debit (DR) balance that keeps growing, you should consider raising your Direct Debit payment to catch up.


If I have been overcharged can I get my money back?

Absolutely you can. If you have overpaid for the amount of energy you have used we will let you know. This can be seen on each of your quarterly bills, or can be viewed in your online account. You can claim this credit back at any point.

Why has my Direct Debit amount changed?

This could be for a variety of reasons:


  • Your meter readings show that you are using more or less energy than we had originally estimated.
  • Your tariff has come to an end or changed. We will notify you ahead of time if this is the case. 
  • A change of circumstances in your home may have led to higher energy consumption. For instance, you are now working from home or have new tenants.

How is my Fixed Direct Debit calculated?

To calculate how much you will pay each month we include:


  • Your projected energy costs
  • The current balance on your account (if you’re owed money or in debt)
  • Divide the combined figure by twelve months
