Why Is My Credit Score So Low? The Most Common Reasons Explained

Your credit score is low because lenders have found something on your credit file that makes you appear higher risk. The most common causes are missed payments, defaults, county court judgements (CCJs), too many recent credit applications, or simply having no credit history at all. Each of these has a different impact and a different timeline for recovery.
Short Summary
Missed payments and defaults stay on your credit file for six years from the date they were recorded. Even a single missed payment can noticeably lower your score, particularly if it was recent.
County court judgements, individual voluntary arrangements (IVAs) and bankruptcies also remain on your file for six years and have a more severe impact than individual late payments.
Having no credit history at all can result in a low score even if you have never defaulted on anything. Lenders need evidence that you can handle credit responsibly, and a blank file gives them nothing to assess.
The good news is that your score is not fixed. Most people can make meaningful improvements within three to twelve months by taking specific steps consistently.
What causes a low credit score?
Several factors can drag your score down, and they do not all carry equal weight.
| Cause | Severity | How long it stays on your file |
|---|---|---|
| Late or missed payment | Moderate | 6 years |
| Default | High | 6 years from default date |
| County court judgement (CCJ) | High | 6 years |
| IVA or debt management plan | High | 6 years |
| Bankruptcy | Very high | 6 years |
| Too many credit applications | Low to moderate | 2 years (hard searches) |
| High credit utilisation | Moderate | Updates monthly |
| No credit history | Moderate | N/A |
The more recent the negative entry, the greater its impact. A default from five years ago matters far less than one from six months ago.
Does a poor credit history from years ago still affect my score?
Yes, if those entries are still within the six-year window. A CCJ registered five and a half years ago is still on your file, though its impact lessens over time. Once the six years pass, the entry drops off automatically.
If you have had a clean record for two or more years since any negative entries, you will have started to rebuild. Lenders often look at recent behaviour, so consistent on-time payments over the last 12 to 24 months can partially offset older problems.
Can too many credit applications lower my score?
Yes. Every time you formally apply for credit, the lender runs a hard search on your file. Each hard search is recorded and visible to other lenders. Multiple hard searches in a short period signal to lenders that you may be in financial difficulty or are being declined repeatedly.
Before applying for a credit card, loan or mortgage, use an eligibility checker. MoneySavingExpert's eligibility tool and comparison sites such as MoneySuperMarket use soft searches that do not appear on your file. This lets you see your approval odds before committing to an application.
Why is my score low if I have never missed a payment?
The most likely explanation is that you have very little credit history. If you have always paid cash, never had a credit card, and never taken out a loan, lenders have no evidence of how you handle borrowed money. A thin credit file scores low by default.
The solution is to start building a history deliberately. Apply for a credit builder card from a provider such as Aqua, Capital One or Vanquis, use it for small regular purchases, and repay the balance in full each month. Within six months you should see your score rise.
Registering on the electoral roll at your current address also helps. It is one of the easiest things you can do and most credit reference agencies use it to verify your identity and address.
Does your credit utilisation affect your score?
Yes, significantly. Credit utilisation is the percentage of your available credit limit that you are currently using. Experian recommends keeping this below 25 per cent. If your total credit limit is £4,000 and your balance is £3,500, your utilisation is 87.5 per cent, which will lower your score considerably.
Paying down balances or requesting a credit limit increase (without spending more) can improve your utilisation ratio quickly. Because lenders report balances monthly, improvements show up within one to two billing cycles.
How quickly can I improve my credit score?
There is no single answer because it depends on what is causing your score to be low.
- If the cause is high utilisation: improvements can show within one to two months of paying down balances.
- If the cause is missed payments: on-time payments from now on begin to rebuild your history, but the missed payment marker remains for six years.
- If the cause is a thin credit file: building history with a credit builder card typically shows results within three to six months.
- If the cause is a default or CCJ: recovery takes longer, often two to four years, though the impact softens over time.
Checking your credit report regularly helps you track progress. ClearScore (Equifax data), Credit Karma (TransUnion data) and Experian all offer free access to your score and report.
Is there anything I can do about errors on my credit file?
Yes. Errors on your credit file can unfairly damage your score and you have the right to dispute them. Contact the relevant credit reference agency directly: Experian, Equifax or TransUnion each have a dispute process on their website.
Common errors include payments marked as missed when they were made, accounts that belong to someone else (particularly an ex-partner), and outdated addresses. The agency must investigate and respond within 28 days under UK data protection rules.
Frequently Asked Questions
How long does a missed payment stay on my credit file?
A missed payment stays on your credit file for six years from the date it was recorded. Its impact on your score decreases over time, particularly once you have established a pattern of on-time payments in the following months and years.
Can I remove a CCJ from my credit file early?
A CCJ can be "set aside" by a court if it was wrongly issued, or "satisfied" (marked as paid) if you repay the full amount within one month of judgement. A satisfied CCJ is less damaging than an unsatisfied one, but it remains on your file for six years regardless. Paying a CCJ more than one month after judgement marks it as satisfied but does not remove it early.
Will checking my own credit score lower it?
No. Checking your own score creates a soft search, which is invisible to lenders and has no effect on your score. Only hard searches triggered by credit applications can reduce your score.
What credit score do I need to get a mortgage?
There is no universal minimum score, as each lender uses its own criteria. Generally, a score in the "good" or "excellent" range with at least one agency will open up the best rates. If your score is lower, specialist lenders including Kensington, Pepper Money and Bluestone offer mortgages to people with impaired credit histories, though rates will be higher.
Should I close old credit accounts to improve my score?
Usually not. Closing old accounts reduces your available credit, which can increase your utilisation ratio and reduce the average age of your accounts. Both effects can lower your score. It is generally better to keep old accounts open and unused unless they carry an annual fee that is not worth paying.
Where can I get free help if debt is affecting my credit score?
StepChange (0800 138 1111) and Citizens Advice both offer free, impartial debt advice. If missed payments or defaults are on your file because of debt problems you are struggling to manage, speaking to an adviser can help you find a structured solution that prevents further damage to your credit file.
