What Happens To Your Direct Debit When You Switch Energy

What happens to your direct debit when you switch energy is straightforward in most cases: your old supplier usually cancels the direct debit automatically once your switch completes, and your new supplier sets up a fresh one based on your expected usage. The detail that trips people up is timing — cancel too early and you can hold up a refund you are owed.

This guide covers when the old direct debit stops, what happens to any credit or debit balance, whether you can end up paying twice, and the rules if you switch while you owe money.

• Your old supplier normally cancels your direct debit automatically when the switch completes — but check it has actually stopped.
• Your new supplier sets up a new direct debit before they take over your supply.
• If you are in credit, your old supplier should refund you — so keep the direct debit active until your final bill is settled.
• Under Ofgem’s Guaranteed Standards, suppliers must issue a final bill within 6 weeks and refund credit within 10 working days, or pay you £30 compensation.

Does your old direct debit get cancelled automatically?

Yes — when you switch energy supplier, your old supplier usually cancels your existing direct debit automatically once the switch completes. You normally do not need to contact your bank yourself. Even so, check your account after the switch to confirm no further payments are leaving, because the cancellation is not always immediate.

Your old supplier will issue a final bill for any outstanding amounts first. Once that bill is settled, the direct debit should be cancelled. As a precaution, it is sensible to confirm with your bank that the old direct debit has stopped after your final bill is paid, so you are not charged again in error.

When should you cancel your direct debit with your old supplier?

Cancel your old direct debit only after your final bill has been settled, not before the switch completes. Ofgem’s guidance is clear: if you are switching, moving or closing an account, keep your direct debit active until your final bill is settled to avoid leaving money unclaimed.

The reason is the refund. If you are in credit and you cancel the direct debit too soon, your supplier cannot pay the money straight back into your account — it may have to send a cheque instead, which takes longer and can go astray if your contact details have changed. Wait for the final bill, make sure any credit has been refunded or any balance cleared, then cancel as a backstop.

If your old supplier collects payments in advance rather than in arrears, it is worth leaving the direct debit in place until you have seen the closing statement, then cancelling once everything is reconciled.

What happens to your new direct debit?

Your new supplier sets up a new direct debit before they take over your energy supply, based on the usage details you gave during the switch. For example, your new monthly direct debit might be set at £50 a month to cover what they expect your bills to be.

You will normally be asked to provide your bank details and agree the payment amount and date during the sign-up process. The first payment is usually collected shortly after your supply start date. If your estimated usage looks too high or too low, you can ask your new supplier to review the amount once they have a meter reading or two.

Will you pay two direct debits in the switch month?

You may see payments go to both suppliers in the month you switch, but you never pay twice for the same energy. One supplier is collecting for the period up to your switch date, and the other is collecting for the period after it. The amounts cover different days of usage, not the same energy billed twice.

This happens partly because some suppliers take payment in advance and others bill in arrears. If you would rather avoid two payments landing close together, you can cancel the old direct debit once your final bill is settled, so only the new payment continues. Check your closing statement to confirm you have only been charged for energy used up to the switch date.

What happens to your credit or debit balance?

If you are in credit when you switch, your old supplier should proactively refund the money left on your account — you do not lose it. If you are in debit, your old supplier produces a final bill using your opening and closing meter readings, and you pay off the balance, ideally promptly.

If you are in credit

If your account is in credit when you switch, your old supplier must refund the remaining balance. Under Ofgem’s Guaranteed Standards of Performance, the supplier must issue a final bill within 6 weeks of the switch and refund any credit within 10 working days of that bill. If they miss the 10-working-day deadline after issuing the final bill, you are entitled to £30 in compensation.

Keep your direct debit live until the refund has been made. If the direct debit is already cancelled, the supplier may have to send a cheque, which is slower. For more on reclaiming money owed, see our guide to getting money back on your electricity and gas bills.

If you are in debit

If you owe money when you switch, your old supplier adds the outstanding amount to your final bill, which you then pay. The bill is based on actual meter readings where possible, so give a closing reading on or near the switch date to avoid being billed on an estimate. Clearing the balance promptly stops interest or chasing and lets the account close cleanly.

Don’t leave credit sitting in a closed account

Around £240 million of unclaimed credit is sitting in closed energy accounts, according to Ofgem figures reported in late 2025, with 1.9 million closed accounts still holding a balance. Most refunds happen automatically — industry body Energy UK says more than 90% of account balances are returned to consumers — but a minority slip through, often because the customer cancelled the direct debit early or changed contact details.

If you switched in the past and never received a refund, contact your old supplier with your old account number and proof of identity to reclaim it. Be alert to scams: Ofgem does not contact energy customers directly about credit they may be owed. If you get an unexpected call, text or email claiming to be from Ofgem about a refund, do not respond or click any links.

Can you switch if you are in debit or owe money?

You can usually switch even if you owe money, as long as the debt is under 28 days old. For a credit-meter (standard direct debit) customer, an Ofgem rule means a supplier can only block your switch if you have owed them money for 28 days or more from when they sent the bill. If the debt is newer than that, you can still switch and the amount owed is simply added to your final bill.

If you owe money for more than 28 days, you generally need to repay the debt before switching. If you are switching specifically because your supplier is putting up prices, you may be given a 30-day window to clear the debt before they can block the switch.

Prepayment meters and the £500 rule

Prepayment meter customers can switch supplier while owing up to £500 for gas and £500 for electricity, under the Debt Assignment Protocol. The protocol covers debts between £20 and £500, and the outstanding balance is transferred to your new supplier rather than blocking the switch. This £500 threshold applies to prepayment meters only — it does not apply to standard direct debit customers, where the 28-day rule applies instead. For more detail, see our guide on the energy price cap and prepayment meters.

How long does the switch take and is your supply ever cut off?

A standard energy switch should take up to 5 working days, and your gas and electricity supply is never interrupted at any point during the change. The same wires and pipes carry your energy — only the company billing you changes.

You also have a statutory cooling-off period of at least 14 days from when you request the switch, during which you can cancel free of charge. Some suppliers voluntarily offer longer, such as 21 days, but 14 days is the legal minimum you can rely on. If a switch goes wrong and your supply is moved in error, Ofgem rules entitle you to compensation of up to £120 if your correct supply is not restored in good time.

Should you switch now or fix your tariff?

Ofgem confirmed on 27 May 2026 that the energy price cap will rise by around 13% for the period 1 July to 30 September 2026. The price cap limits the unit rates and standing charge for a typical household paying by direct debit — it is not a fixed cap on your total bill, which still varies with how much energy you use.

For a typical household, the cap-level bill was about £1,641 a year up to 30 June 2026, expected to rise to around £1,862 from 1 July 2026 based on currently published Ofgem figures (these are time-dependent and should be checked against the latest Ofgem announcement). With a rise on the way, some households compare a competitive fixed-price energy tariff against staying on the cap. Switching to a fixed deal sets up a new direct debit in the same way as any other switch, with the same final-bill and refund protections on your old account.
