Energy Direct Debit Refund: How to Reclaim Your Credit Before Winter

Why your energy account builds up credit over summer

If you pay for your gas and electricity by fixed monthly direct debit, an energy direct debit refund might be sitting in your account without you knowing. Your supplier collects roughly the same amount every month, but you use far less energy in the warmer months, so your balance quietly climbs through spring and summer.

That is by design. The idea is that the credit you build up over summer covers the heavier bills in winter, so your payments stay level all year. It is a sensible system when the numbers are set correctly.

The problem is when they are not. If your direct debit was set too high, or your usage has dropped, the credit can grow well beyond what you will need for winter, and that is money the supplier is holding rather than you. Early autumn, before the heating goes back on, is the moment your balance is at its highest and the best time to check.

Does my energy supplier owe me a refund?

Possibly, if your account is sitting in healthy credit at the point in the year when balances are normally at their highest. Under Ofgem rules you can ask for excess credit back at any time, and your supplier must either return it or explain why it is keeping the money.

It helps to know the scale of this. According to Ofgem’s credit balance data, the average household paying by fixed direct debit was around £200 in credit across the year to June 2025, and credit balances tend to peak over the July to September quarter. Around 17 million households pay this way, so collectively that is a large amount of customer money held by suppliers as winter approaches.

None of that means every account is owed a refund. It means it is worth checking yours, because the end of summer is exactly when an overpayment is most likely to be sitting there.

How do I get an energy direct debit refund?

Getting an energy direct debit refund is usually quick, and the single most important step is giving an accurate, up to date meter reading first. A refund based on an estimate can leave your account short later, so a real reading protects you.

Here is the order that tends to work best:

1. Submit a current reading. Take a photo of your gas and electricity meters, or let your smart meter send an automatic reading, so the balance reflects what you have actually used. If you are unsure how, our guide to reading your smart gas and electricity meters walks through it.
2. Check your balance. Log in to your online account or app and look at your current credit or debit position.
3. Request the refund. Many suppliers, including the larger ones, have a refund button in the app or online account. If yours does not, use live chat or phone and ask plainly to reclaim your excess credit.
4. Keep a record. Note the date and the figures, so you can follow up if the money does not arrive within the timescale your supplier quotes.

If a request is refused, your supplier should explain how it worked out the amount it is keeping. You can ask it to review your direct debit at the same time so the balance does not simply build straight back up.

Should you leave some credit in your account?

Often, yes. A modest buffer going into autumn is sensible, because your usage will climb again as the heating goes back on, and a sensible cushion stops you tipping into debt in the depths of winter.

There is no single right number, because it depends on how much energy you use and how your payments are spread. The fairer test is whether the credit is clearly more than you would reasonably burn through over the colder months. If it is, that surplus is a candidate for a refund, while a reasonable winter buffer is worth keeping in place.

What if my direct debit looks too high?

Reclaiming a one off lump of credit only fixes the symptom. If your monthly direct debit is set higher than your actual usage justifies, the credit will keep stacking up and you will be back here next autumn.

Ask your supplier to review the payment amount alongside any refund. A direct debit should be based on a fair estimate of your annual usage, spread across twelve months, not set so high that it parks a large balance with the supplier. If your usage has genuinely fallen, point that out and ask for the payment to be recalculated.

Equally, resist the urge to cut it too far. A direct debit set too low builds a debt that has to be cleared later, often at the worst time of year. The aim is a payment that matches what you actually use. Roo’s rule of thumb: the right direct debit is the one that leaves you close to zero at the end of winter, not the one that feels cheapest today.

Check your balance before you switch or fix

Early autumn is a natural moment to review your energy, and your credit balance is part of that decision. If you are thinking of moving to a new deal before the colder months, check the balance first so you know where you stand before anything changes hands.

When you switch supplier, any credit on your account should be refunded by the old supplier once your final bill is settled, so it is not lost. Even so, it is worth noting the figure beforehand so you can check it comes back. The same applies if you are weighing up fixing your energy tariff, where the headline you should compare is the deal itself rather than your current balance.

Ofgem has also been reforming this area, with proposals that could see large amounts of customer credit returned more automatically and a push to reunite people with money sitting in closed accounts. Until that fully lands, the safest approach is the simple one: read your meter, check your balance, and ask for what is yours.
