Many people discover that applying for an overdraft is more involved than expected — and that being declined, or relying on one too heavily, can signal a wider financial problem worth addressing. Since April 2020, UK banks have been required to charge a single annual interest rate on overdrafts, bringing their true cost into sharper focus. For many borrowers, the rate — typically 39.99% EAR — is higher than anticipated.

How Overdraft Applications Work in the UK
When someone applies for an arranged overdraft — either on a new current account or as an addition to an existing one — the bank or building society carries out a formal assessment. Lenders have regulatory obligations to lend responsibly, and the process involves several distinct checks before a limit is offered or declined.
What Lenders Check
The assessment typically covers the following areas:
- Credit history: Lenders carry out a credit search — usually a hard search — to review the applicant's credit file. This includes repayment history on existing borrowing, any missed payments, defaults, County Court Judgments (CCJs), Individual Voluntary Arrangements (IVAs) or bankruptcies.
- Income and expenditure: Many banks request confirmation of income, or use open banking data with the applicant's consent, to assess whether the overdraft can be repaid.
- Existing debts: The total amount already owed — on credit cards, loans, other overdrafts — is factored into an affordability calculation.
- Account behaviour: For existing customers applying for an overdraft extension, the bank will review how the account has been used, including whether it is regularly overdrawn or whether payments are frequently made late.
There is no universal minimum credit score required to obtain an overdraft. Each lender sets its own internal criteria, and the outcome depends on the combination of factors above rather than any single figure.
Arranged vs Unarranged Overdrafts
An arranged overdraft is one agreed in advance with the bank up to a set limit. An unarranged overdraft occurs when spending exceeds the account balance without a prior agreement, or when it exceeds the agreed limit. Since April 2020, banks have been required to charge the same annual interest rate for both arranged and unarranged overdrafts — they can no longer impose higher fees for unarranged use. Banks can, however, still refuse transactions or close accounts where unarranged overdraft use is persistent.
Banks in the UK are required to price arranged and unarranged overdrafts at the same annual interest rate. The typical rate across major UK banks is 39.99% EAR — significantly higher than many standard credit card rates.
Interest Rates and the True Cost of an Overdraft
Before April 2020, banks used daily fees, monthly fees and penalty charges in ways that made it difficult to compare the real cost of different overdrafts. Since the rule change, a standardised Annual Equivalent Rate (AER or EAR) must be applied and disclosed clearly.
Most major UK banks now charge 39.99% EAR on overdrafts. This is broadly similar to — or higher than — many credit card interest rates. For someone who remains in their overdraft for extended periods, the cumulative interest can become significant. As a straightforward illustration: being £500 overdrawn for an entire year at 39.99% EAR would generate approximately £200 in interest charges.
Some banks offer interest-free buffers — typically £25 or £50 — meaning no interest is charged on small, short-term overdraft use below that threshold. These buffers vary by bank and are not guaranteed. The terms of any overdraft should be confirmed directly with the provider.

What Happens If an Overdraft Application Is Declined
A declined overdraft application carries implications worth understanding. A hard credit search will have been recorded on the applicant's credit file regardless of the outcome. Multiple hard searches in a short period can affect credit scoring models used by future lenders.
Common Reasons for Rejection
- Poor or limited credit history
- Recent missed payments or defaults on other accounts
- An existing high level of debt relative to income
- A CCJ, IVA or bankruptcy on record
- The applicant being under 18 (overdrafts are not available to minors)
- Not meeting the bank's internal affordability criteria
If an application is declined, the bank is not required to provide a detailed explanation in all circumstances, though under regulatory guidance it must explain the general reasons on request where a credit reference agency was involved.
Checking a Credit File
Anyone who has been declined credit — including an overdraft — has the right to access their credit file. The three main UK credit reference agencies are Experian, Equifax and TransUnion. Statutory access is free of charge under data protection law. Reviewing the file can help identify errors, outdated entries or markers that may be addressed over time.
Under the UK GDPR and the Consumer Credit Act 1974, anyone has the right to request a copy of the data held about them by a credit reference agency. This statutory credit report is available at no cost.
When Overdraft Use Becomes a Debt Problem
For some people, an overdraft is not just a short-term buffer — it becomes a persistent state. Being permanently overdrawn, regularly reaching the overdraft limit, or using an overdraft to cover essential costs such as rent or food are indicators that the overdraft has shifted from a convenience into a debt problem.
Overdraft debt is treated as unsecured debt in UK insolvency procedures in the same way as credit card debt or personal loans. This means it can, in principle, be included in formal debt solutions such as a Debt Relief Order (DRO), a Debt Management Plan (DMP), an Individual Voluntary Arrangement (IVA) or bankruptcy. According to GOV.UK, the suitability of any of these routes depends on an individual's full financial picture and is something only a regulated debt adviser can properly assess.
It is also worth noting that banks have the right to reduce or remove an overdraft facility with notice, or to request repayment of an overdrawn balance. According to GOV.UK guidance on current accounts, banks must give notice before making changes that are not in the customer's favour. This can occur if account behaviour changes, if affordability concerns arise, or if the bank updates its credit policies.
The Risk of Using One Form of Borrowing to Cover Another
A pattern that can accelerate financial difficulty is using new borrowing — including a new overdraft — to cover existing debt repayments. This does not reduce the overall level of debt; it shifts it, often at similar or higher interest rates. Someone in this position may find it helpful to speak to a regulated debt adviser who can review all debts together rather than each one in isolation.
Alternatives to an Overdraft
If an overdraft is unavailable, or if the cost is prohibitive, there are other options worth being aware of:
- Credit union loans: Credit unions are member-owned financial cooperatives. They can offer small loans at interest rates capped by law at 42.6% APR in England, Scotland and Wales, according to GOV.UK. Some operate emergency loan schemes specifically designed as alternatives to high-cost credit.
- Budgeting Loans and Budgeting Advances: According to GOV.UK, people receiving certain means-tested benefits may be eligible for an interest-free Budgeting Loan (for those on legacy benefits) or a Budgeting Advance (for those on Universal Credit). These are repaid from future benefit payments.
- Local authority hardship funds: Many local councils operate discretionary funds for residents facing acute financial hardship. Eligibility and availability vary by area.
- Employer salary advances: Some employers offer salary advance schemes that allow employees to access a portion of earned wages before payday. Terms vary significantly between employers.
These alternatives carry their own eligibility criteria and implications. None of them automatically resolves an underlying debt problem if one exists — they may provide short-term breathing room, but a longer-term plan may also be needed.
