Does an overdraft affect your credit score? Yes, but how depends on how you use it. An arranged overdraft that you stay well within, and clear regularly, is unlikely to hurt your score and can gently help by showing you handle credit responsibly. Sitting near your limit, slipping into an unarranged overdraft, or missing repayments leaves negative marks that can follow you for up to six years.
How Your Overdraft Shows Up on Your Credit File
UK banks share overdraft information with the three main credit reference agencies: Experian, Equifax, and TransUnion.1Citizens Advice. How Lenders Decide Whether to Give You Credit Once your bank grants an overdraft facility, it appears on your credit file as an open credit account, recording the agreed limit, the date it was opened, and your current balance. The entry stays visible for as long as the account is open, even in months when you never actually use it.
Other lenders see this facility when they check your file. They treat the agreed limit as potential debt you could draw on at any time, so it factors into their overall picture of your borrowing. After you close the account, the record remains for six years before dropping off.2Experian. Credit Reference Data Retention Periods
When Overdraft Use Helps or Barely Touches Your Score
Credit utilisation is the share of your overdraft limit you are actually using. On a £1,000 overdraft, being £700 in means 70 percent utilisation. Scoring models treat high utilisation as a sign you are stretched, and your score drops accordingly. Keeping utilisation below roughly 30 percent is widely recommended for a healthy profile.
Staying at or near zero, dipping in only occasionally and clearing the balance quickly, sends the strongest signal. It shows the overdraft is a safety net rather than something you rely on month to month.3Experian.

When an Overdraft Damages Your Score
Spending beyond your agreed limit, or dipping into an unarranged overdraft, breaches the terms of your account. Your bank can report this to the credit reference agencies as a missed or late payment marker. These markers tell future lenders you lost control of your finances, and a single one stays on your file for six years.5Experian. Late Payments – How They Impact Your Credit Score
Regular use of an unarranged overdraft is particularly damaging because it suggests consistent spending beyond your means.3Experian. How Does an Overdraft Affect Your Credit Score Even small amounts carry roughly the same weight as missing a payment on a credit card or loan.
The most serious entry is a default. It happens when your bank decides the lending relationship has broken down, typically after several months of being overdrawn with no sign of repayment. Before recording a default, the bank must send a formal default notice giving you at least 14 days to bring your account back within its limit or agree a repayment plan.6Citizens Advice. If You’re Struggling With Your Overdraft If registered, the default remains on your credit file for six years from the date recorded.7TransUnion UK. How Long Does Information Stay on My Credit Report For During that time most mainstream lenders will reject applications or offer worse terms. Agreeing a repayment plan after a default does not remove it, but it shows later lenders you took steps to deal with the debt.
Applying for or Increasing an Overdraft
Applying for a new overdraft, or asking for a higher limit, usually triggers a hard search on your credit file. Other lenders can see hard searches, which stay on your report for two years.7TransUnion UK. How Long Does Information Stay on My Credit Report For A single search causes only a small, temporary dip, but several in quick succession look like someone urgently seeking credit.
Many banks run an eligibility check with a soft search first. That gives you a sense of whether you would be approved without leaving a mark other lenders can see.3Experian. How Does an Overdraft Affect Your Credit Score The hard search only happens when you commit to a formal application, so using the eligibility checker first helps you avoid stacking up hard searches you did not need.
A Large Unused Overdraft
Having a large overdraft that you never touch will not directly lower your credit score. It can still work against you during an affordability assessment, which lenders run alongside the score itself. Affordability checks weigh your income, outgoings, and the total credit available to you, including unused overdraft facilities. A lender may worry you could draw on a large unused limit at any point and overstretch yourself.
If your limit is much bigger than you need, consider asking your bank to reduce it before applying for a mortgage or other significant borrowing. A smaller facility removes that concern from the affordability picture.
Overdrafts and Mortgage Applications
Mortgage lenders look at your finances more closely than almost anyone else. You will typically need to provide three months of bank statements, so regular overdraft use will be visible.3Experian. How Does an Overdraft Affect Your Credit Score A mortgage provider will also fold any outstanding overdraft balance into your overall unsecured debt for affordability calculations.
Consistent use, sitting close to your limit, rarely clearing the balance, or dipping into an unauthorised overdraft, suggests someone not in control of day-to-day spending. Every lender applies its own criteria, but your overdraft could affect the decision if it suggests you would struggle to meet mortgage repayments on top of what you already owe.3Experian.

If You’re Struggling to Get Out of Your Overdraft
The Financial Conduct Authority expects banks to help customers who rely heavily on their overdraft. If you are frequently overdrawn, your bank should contact you to discuss ways to reduce that dependence. Options can include waiving or reducing interest, offering a structured repayment plan, or converting the overdraft balance into a personal loan at a lower rate.6Citizens Advice. If You’re Struggling With Your Overdraft You can also ask proactively for your limit to be reduced gradually, lowering it by a set amount each month, so you wean yourself off the facility over time.
If overdraft debt is part of a wider financial crisis, you may qualify for the government’s Breathing Space scheme. Overdrafts are a qualifying debt.8GOV.UK. Debt Respite Scheme (Breathing Space) Guidance for Creditors A standard breathing space lasts up to 60 days, during which your bank must pause enforcement action, stop contacting you to demand repayment, and freeze most interest and charges. A mental health crisis breathing space lasts for the duration of treatment plus 30 days.
You cannot apply directly. You need a debt adviser, such as one from Citizens Advice or StepChange, to assess your situation and submit the application. During the protected period you are expected to engage with debt advice and work toward a longer-term solution. Breathing space does not wipe out the debt or remove existing marks from your credit file, but it buys time to deal with your finances without charges piling up.
