Unpaid Transaction Fees

An unpaid transaction fee is what a bank charges when it refuses to pay something from your account because there is not enough money to cover it. MoneyHelper describes it as "a fee if you don't have enough money to cover a payment, usually called an unpaid transaction fee"¹. It is charged per item refused, so a Direct Debit, standing order or card payment that bounces can each attract one.

The amount varies by bank. NatWest and RBS charge £1.55 per returned transaction², while Bank of Ireland UK charges £1.50 for each item it refuses to pay, charged monthly⁴. Halifax charges £0 for refused payments on its Current Account, Reward Current Account, Ultimate Reward Current Account and Student Current Account as at 30 June 2026⁶. Some banks cap the total: RBS charges £1.55 in any charging period for unpaid transactions, with a maximum of one per charging period².

The charge is not the same as interest on an overdraft, and it is not a penalty for going overdrawn by agreement. It applies when a specific payment is refused. If several payments are refused in the same month, the fees can add up quickly, and if the account is already short, the fee itself can deepen the overdraft.

When the fee applies: payments your account cannot cover

The fee is triggered by a specific event: a payment instruction arrives, the bank checks the balance, and there is not enough money to pay it. MoneyHelper's wording is precise: it is "a fee if you don't have enough money to cover a payment"¹. That covers Direct Debits, standing orders, cheques and card payments presented for payment.

Banks describe the mechanism in similar terms. NatWest says an Unpaid Transaction Fee is charged for a transaction that is returned unpaid by your bank or lender⁷. RBS says a fee of £1.55 applies when it returns a transaction unpaid⁸. Ulster Bank uses the same wording and the same £1.55 figure⁹.

The fee is separate from overdraft interest. If you have an arranged overdraft and the payment fits within it, the payment goes through and you pay interest instead. If the payment would take you beyond the limit, or there is no overdraft at all, the bank can refuse it and charge the unpaid transaction fee. StepChange notes that banks will charge a fee to cover payments where there is not enough money in your account¹¹.

Some accounts avoid the charge altogether. Basic bank accounts, which have no overdraft facility, typically carry no fees for returned Direct Debits or standing orders¹². Citizens Advice confirms that on a basic account, if you have set up a Direct Debit and there is not enough money to pay for it, you might be charged, so the terms still matter¹³.

Unpaid transaction fee: £1.55 per item at NatWest and RBS

NatWest and RBS both charge £1.55 per returned transaction². The wording on NatWest's overdraft page is direct: "An Unpaid Transaction Fee of £1.55 is charged for a transaction that we return unpaid"³. RBS uses the same figure and the same construction².

There is a cap at RBS. Its support page states: "£1.55 in any charging period for unpaid transactions, with a maximum of 1 per charging period"². That means if several transactions are refused in the same charging period, only one £1.55 fee applies. NatWest's page does not state the same cap in the same words, so the practical effect can differ between the two brands even though they share the same headline figure.

Ulster Bank, which operates in Northern Ireland, also charges £1.55 per returned transaction⁹. Its unarranged overdraft page repeats the figure¹⁰. For students and graduates, RBS's Graduate Overdraft charges an unpaid transaction fee of £1.55, with a maximum of £1.55 in a monthly charging period¹⁴.

The fee is not the only cost of a refused payment. If the refusal leaves the account overdrawn, or deepens an existing overdraft, interest and other charges can follow. StepChange warns that using an unauthorised overdraft means paying very high charges as a result¹⁵. The £1.55 is the visible charge; the overdraft position it creates is the one that can grow.

Clear Account: £1.50 for each refused item, charged monthly

Bank of Ireland UK charges £1.50 for each item it refuses to pay, and the charge is applied monthly⁴. The Clear Account page states: "Unpaid Transaction Fee | £1.50 for each item we refuse to pay and this will be charged monthly"⁴. The charges explained document repeats the same figure and the same monthly timing⁵.

The same £1.50 charge appears across Bank of Ireland UK's other current accounts. The Graduate Account, the GMS Borrowing Account, the Elective & Intercalated (E&I) Borrowing Account and the IPLS Borrowing Account all carry an unpaid transaction fee of £1.50 for each item refused, charged monthly¹⁶. The consistency across the range means the account type does not change the fee, only the circumstances in which it is charged.

Bank of Ireland UK also sends text alerts when a payment is refused. Its support article describes the scenario: "so we declined these payments and you will incur unpaid transaction fee(s)"¹⁹. The alert is designed to tell you the payment has been refused before the monthly charge is applied, giving you a chance to move money across.

Danske Bank charges £1.50 for a refused payment on its Choice account, as at 30 June 2026²⁰. Halifax charges £0 for refused payments on its Current Account, Reward Current Account, Ultimate Reward Current Account and Student Current Account, also as at 30 June 2026⁶. The range across the market is therefore wide: from nothing at all to £1.55 per item, with the monthly or per-period cap making a bigger difference than the headline figure in a month with several refusals.

Formerly the returned item fee: what the rename changed

The charge has not always been called an unpaid transaction fee. RBS renamed it in September 2013: the Returned Item Fee became the Unpaid Transaction Fee, and the Unarranged Overdraft Fee became the Unarranged Overdraft Usage Fee²¹. The change was a rename, not a change to when the fee applies or how much it costs.

The old name still appears in some places. Danske Bank's Direct Debit page refers to a returned item fee of £1.50 for each Direct Debit refused, up to a total charge of £4.50 per month²⁰. That is the same kind of charge under the older label. If you see "returned item fee" on a statement or in a terms document, it means a payment was refused because the account could not cover it.

The rename matters for two practical reasons. First, if you are searching for the charge on your statement, both names refer to the same thing. Second, if you are comparing accounts, a bank that uses one term and a bank that uses the other may still be charging for the same event. The label is not a guide to whether the fee is charged, only to what the bank calls it.

Some banks have removed the charge entirely. HSBC lists its returned payment fee as "Removed"²². That does not mean every refused payment is free at every bank, but it shows the charge is not universal. Where a bank has removed it, the cost of a refused payment falls on the missed payment itself and any overdraft interest, not on a separate fee.

How often the fee is taken, and what it does to your balance

The frequency depends on the bank's charging model. A per-item model charges for each payment refused, so three refused Direct Debits in a month mean three fees. A capped model charges once per period regardless of how many payments are refused. RBS's cap of one £1.55 fee per charging period is the clearest example². Bank of Ireland UK's monthly charge of £1.50 per item sits between the two: it is per item, but applied monthly⁴.

The timing matters because the fee is usually taken from the account after the refusal. If the account is already short, the fee can push it further overdrawn. Overdrafts are repayable on demand, which means a bank can ask for the whole amount back at any time²³. Using an unauthorised overdraft means paying very high charges as a result¹⁵. The unpaid transaction fee is one charge among several that can apply when an account is under pressure.

Northern Ireland's official guidance sets out the wider consequences: you may have to pay a penalty charge and a high rate of interest, your bank may charge for sending a reminder letter and for Direct Debits or cheques put through the account, and it may freeze the account until the overdraft is paid off²⁴. Those consequences sit alongside the unpaid transaction fee, not instead of it.

If you are overdrawn, switching bank accounts can be harder. Independent Age notes that if you are currently overdrawn, you might not be able to switch until you have paid off the overdraft²⁵. That can trap you in an account with fees you want to escape.

What protects you, and where it stops

The main protection is the refund rule for unauthorised payments. Under the Payment Services Regulations 2017, where an executed payment was not authorised, the payment service provider must refund the amount and restore the account to the state it would have been in had the transaction not taken place²⁷. That covers payments taken without your authority, not payments you authorised that were then refused for lack of funds.

The distinction matters. If you cancel a continuous payment authority and money is still taken, that is an unauthorised payment, and your card issuer should give you a refund including any interest or charges added because the payment was taken²⁸. If you authorised a Direct Debit and it bounces because there is not enough money, the unpaid transaction fee is a charge for the refusal, not an unauthorised payment, and the refund rule does not apply.

There is a liability limit for unauthorised payments taken before you notify the bank: you may have to pay up to £35³⁰. That is a cap on your liability, not a fee the bank charges for a refused payment. NS&I's policy is to return the account to the position it would have been in had the unauthorised payment not happened, unless the customer failed to take reasonable care or did not report lost security details promptly³¹.

For credit cards, a different rule applies. Charges of more than £12 for missing a credit card repayment may be seen as unfair²². That is a fairness threshold for credit card default charges, not a cap on current account unpaid transaction fees. If you are charged an unpaid transaction fee and think it is unfair, you can complain to your bank and, if unresolved, to the Financial Ombudsman Service.
