How do Direct Debits work?

A Direct Debit is an automatic monthly payment set up with your bank or building society. It means you can choose which day you want the payment to go out each month, and your bank will sort the rest.

Once a Direct Debit is set up, you don’t need to do anything else.

It’s often the best way to make regular payments, such as your energy bill.

Why paying by Direct Debit is the best way to pay

Direct Debit is usually the best way to pay bills because:

• you get a cheaper rate if you’re on our variable Simpler Energy plan
• you don’t have to think about it – it’s all done automatically each month
• you don’t need to worry about forgetting or missing a payment
• it can help you budget as you know how much is going out of your account each month and when
• it spreads your energy costs evenly

How we work out your Direct Debit amount

To work out your monthly Direct Debit amount, we:

• look at your energy use so far and estimate how much you’re likely to use by 31 March 2026. This includes any costs, such as standing charges and add-ons
• take away your current balance, factoring in any credit or debt
• divide the result by the number of payments left until 31 March 2026, which gives us your monthly amount

We aim to bring your balance to £0 by 31 March 2026. This way, you won't owe us anything, and we won't owe you anything, making it easier to manage your energy costs.

We regularly check your Direct Debit to make sure your balance is on track.

Why your Direct Debit amount might be different to your bill amount

Your energy use can vary from month to month, which means your actual bill may differ from your Direct Debit amount. 

To make sure you're paying the right amount, we spread your costs evenly, covering your total energy use until 31 March 2026.

Why meter readings are important

You can make sure your Direct Debit amount stays at the right level by giving us regular meter readings – once a month is best.

How we work out your Direct Debit amount when you join us

When you apply to switch to us, we’ll use your annual usage figures,  If you’re new to OVO, we work out your Direct Debit amount to cover your expected energy use until 31 March 2026. We base it on your past year’s energy use if you know it. If we don’t know it, we’ll ask you about your property and how many people live there, then we’ll base it on the average data for your type of household. After 1 month we check in to make sure the amount you’re paying is right for your actual energy use. Your Direct Debit amount might then need to go up or down.

How often we check you’re paying the right amount

We review your Direct Debit regularly to make sure you are paying the right amount for your energy use. 

We let you know if your Direct Debit amount needs to change to keep your balance on track to reach £0 by 31 March 2026.

When your payment amount might change

Your payments might need to go up or down if something changes, such as:

• your energy use goes up or down
• the price of energy goes up or down – if you’re on a standard variable tariff
• you change which energy plan you’re on
• you missed a payment or recently requested a refund
• you’ve chosen an add-on, such as Greener Energy or OVO Foundation

If your Direct Debit is too high or too low, then we’ll let you know we’re going to have to change the amount.

If your balance is in credit

It’s normal for your balance to build up in summer when energy use is lower. This helps put extra money aside for higher winter bills, when most people use more energy to heat their homes.

We check you’re paying the right monthly amount so your balance stays on track to reach £0 by 31 March 2026.

Even if your balance is in credit, it might be that we still need to increase your monthly payments. This would be if we’ve worked out what your energy use is likely to be and that your balance is likely to go below £0 by 31 March 2026.

If your balance goes below zero

If your balance goes below zero, we’ll let you know if your monthly Direct Debit amount needs to go up.
