When a Direct Debit amount can change and the notice you must get

A Direct Debit is not a fixed payment. It is an instruction that lets a company collect money from your account, and the amount, the date or the frequency can all change over time. The main advantage of a Direct Debit is exactly that flexibility, because the payments can vary in amount or frequency¹. What protects you is the notice: if there are any changes to the amount, date or frequency of your Direct Debit, the payee company must notify you in advance².

The standard rule is 10 working days. Under the Direct Debit Guarantee, the organisation collecting the payment will normally notify you 10 working days in advance of your account being debited, or as otherwise agreed³. That phrase, "or as otherwise agreed", matters: some firms set their own period, and the range runs from 3 working days to 11.

If a payment is taken without the notice you were due, you have a route back. The Direct Debit Guarantee entitles you to a full and immediate refund where a payment error is made by the company or your bank², and banks can reverse an unauthorised collection through the direct debit indemnity process, which covers payments taken without the required advance notice of a change of amount or date⁴.

A Direct Debit can change amount, date or frequency, with notice

The flexibility is the point. A Direct Debit lets a company collect a different sum each time, which suits bills that move around, such as energy, and it lets the collection date shift. The trade-off is that the company is in control of when and how much is taken⁷. The amount may differ each time, but companies should tell you in advance how much they will take and when⁸.

That notice is not a courtesy, it is a condition of the scheme. The payee, the company or person you are paying, must notify you in advance each time this happens². The Financial Ombudsman Service puts it just as plainly: the business must always notify you before making any changes to payments⁹. A company must tell you before it changes your Direct Debit payment¹⁰.

In practice the notice usually arrives as a letter, an email or a message in an app, telling you the new amount and the date it will be collected. It is worth keeping, because it is the record that shows whether you were told in time. Where a change is a price rise rather than a change to the collection itself, the notice rules can differ: a credit card provider that wants to increase the interest on your deal must notify you at least 60 days before the change¹¹, which is a separate regime from the Direct Debit scheme's own rule.

The notice rule: 10 working days before your account is debited

The 10 working day figure appears across the scheme's own wording and in the guidance banks and building societies publish. Government guidance states it directly: we will notify you 10 working days in advance of your account being debited¹². The same period is repeated in the Direct Debit Guarantee wording used by lenders and building societies³, and in independent guidance, which describes the notice as normally 10 working days¹⁸ and usually 10 days¹⁹.

Not every firm uses 10. The spread runs from 3 working days to 11:

The variation is allowed because the guarantee itself says "or as otherwise agreed". A shorter period is not automatically a breach if it is the agreed term, but a company that takes a different amount with no notice at all has stepped outside the rule. Where the change is to the date rather than the amount, independent research on payment flexibility notes that you cannot change the day without giving at least 10 days' notice²³.

Does the 10 working days include weekends and bank holidays?

No. Working days are weekdays excluding weekends and bank holidays⁵, so 10 working days is about a fortnight of calendar time. That matters when you are counting backwards from a payment date to work out whether notice arrived in time.

Direct Debits themselves are only collected on working days. If your Direct Debit is due on a non working day such as the weekend or a bank holiday, it will debit the following working day²⁴. The same rule is described by HSBC: the scheme allows businesses to collect money from your current accounts on certain dates, excluding weekends and bank holidays⁵.

There is a knock-on effect if you cancel close to a weekend payment. If a Direct Debit is cancelled less than 3 working days before a payment due at the weekend, the amount shows as having left the account and the balance is adjusted on Tuesday morning, or Wednesday if Monday is a bank holiday²⁴. So a payment you thought you had stopped can still appear over a long weekend and be put right at the start of the following week.

Changes you ask for yourself: provider cut-off dates

When you want the amount or date changed, the request usually goes to the company you are paying, not your bank. To make changes such as changing the payment date, you will need to contact the company you are paying²⁵. Some providers handle it directly: after the first payment, the Cambridge Building Society lets you change the direct debit date and details by phone or in store²⁶.

Each provider sets a cut-off, and they are not all the same:

• Yorkshire Building Society: at least 3 working days before your payment is due to set up or change a direct debit²⁷
• Leeds Building Society: at least three working days before your Direct Debit collection date²⁸
• Yorkshire Building Society mortgages: at least 3 working days before your next payment to change the Direct Debit date²⁵
• Scottish Widows Bank: you can change the date and amount whenever you choose, provided you give three working days notice²⁹
• Bestinvest: changes made less than 10 working days before the Direct Debit is usually taken may still come from your old account or may not go through¹⁷

The pattern is that a few working days is enough for a straightforward change, but anything close to the collection date risks the old instruction running one more time. If you are moving the payment to a new account, allow more than the minimum. One provider notes that reducing a Direct Debit amount is not always immediate and could take a few days²³.

Do energy suppliers have to give notice before raising my Direct Debit?

Yes, and this is where most people meet the rule. Your supplier has to let you know about a payment increase before it happens, which is described as the direct debit guarantee⁶. Your supplier should give you reasonable notice of any changes to your direct debit payments³⁰, and if it increases its prices it should tell you in a reasonable amount of time before the change takes place³⁰.

The notice period for energy varies by supplier. Citizens Advice puts it at between 3 and 10 days⁶. Under the Direct Debit Guarantee, your energy supplier must tell you about making any changes to your direct debit at least 10 working days in advance¹⁶.

A worked example from Citizens Advice shows how a rise is built: a supplier raises your direct debit payments to £120, which covers your higher usage and paying off the arrears⁶. That is the usual shape of an energy increase, part current use and part catching up on a shortfall.

If you think the new amount is wrong, the first step is to contact the supplier with your meter readings and usage. If that does not resolve it, a complaint can go to the Energy Ombudsman once the supplier has had a chance to put it right.

What happens if I change my Direct Debit just before the payment date?

Timing is the usual trap. If there is a change in the amount to be paid on the payment date, the person receiving the payment must notify you in advance¹, and a company must tell you before it changes your Direct Debit payment¹⁰. But when you are the one making the change, the cut-off works against you.

Several providers ask for at least 3 working days before the payment is due²⁵, and Scottish Widows Bank asks for three working days notice²⁹. Bestinvest warns that if you made the changes less than 10 working days before your Direct Debit is usually taken, it may still come from your old account or may not go through¹⁷.

The practical effect is that a change made in the last few days before collection can produce two payments, or a payment from an account you had closed. If you are switching the account a Direct Debit is paid from, the safer sequence is to set up the new instruction first and leave the old account funded until you can see the payment has moved. Our guide to switching your bank account sets out the full checklist, including the switching service that moves regular payments for you.

What to do if you were not given proper notice

Start with your bank. Direct debits are covered by the Direct Debit Guarantee, and if the bank, or an organisation you are paying, makes a mistake, your bank must refund the payment to you⁹. If a payment error is made by the payee company, or your bank or building society, you are entitled to a full and immediate refund of the amount paid². The guarantee states that your bank should refund disputed payments without question, pending further investigation¹.

The mechanism banks use is the direct debit indemnity. This is a way of claiming back unauthorised direct debits, and it includes instances where you have not been given the required advance notice of a change of amount or date, or have been debited an incorrect amount, earlier than the agreed date or in error⁴. The qualifying reasons are set out as: not given advance notice regarding a change of amount or date; a payment taken earlier than the agreed date; an incorrect amount; or a payment taken in error⁴.

If you cancel a Direct Debit before the cut-off time and it is still taken, and the bank has received all the required information from you, Starling Bank states it will give you a refund straight away³⁴. That is one provider's stated practice, but it reflects the scheme rule that a disputed payment should be refunded while the bank investigates.

A Direct Debit can be cancelled at any time by contacting your bank or building society, and written confirmation may be required; the organisation being paid can also be notified². Cancellation can be done online, in-app, on the phone or in writing³⁴. To move the date instead, the company being paid is the one to contact²⁵.

If the company will not put things right, you can complain formally. Our guide to writing an effective complaint covers how to set out the facts and what you are asking for, and free consumer advice when a dispute with a firm stalls explains where to go next, including the Financial Ombudsman Service, which can look at regular payment problems⁹. In Northern Ireland, the Consumer Council also handles complaints about financial services².
