We explore seven of the most common reasons why this happens.
Understanding why your score may have gone down is a great way to help you decide what to do next. It can also help you anticipate when your score might drop again in the future, so you're not hit with a nasty surprise.
Put simply, your credit score can go down if a lender reports any 'negative' information to the credit reference agencies (CRA). If the new information the lender reports to the CRA makes you seem like a less reliable borrower, it can cause your score to drop.
Here are seven possible negative factors that could be the reason behind your score going down:
Missing or late payments
It’s probably no surprise that paying late or missing a payment on a debt can negatively impact your score.
However, just one late payment, will have less of an impact on your credit score than if you always miss payments.
That's why, even if it's really late, it's always worth making every payment. The longer you leave it to pay a missed payment, the bigger the dent it could make on your credit score. If you’re more than 30 days late making a payment, it’s likely that you’ll see your score drop even more.
An account has gone into arrears
If you miss a payment on a debt, your account goes into arrears straight away. If you continue to miss payments - typically over three to six months - the lender may issue a formal Default Notice under the Consumer Credit Act 1974, marking the account as defaulted. A default means the lender considers the relationship to have broken down and can take further action to collect the debt.
When this information gets added to your report by the lender, it may have a significant negative impact on your score.
A spike in how much credit you use
Your total available credit limit is the amount you’re able to borrow across your credit accounts. (This normally just means credit cards, since loans and mortgages don’t have a flexible credit limit).
With your credit limit, it’s all about balance. Using too little (or no) credit could harm your score, as you’re not able to prove to lenders how you manage credit. However, using too much of your credit limit could suggest to lenders that you'd struggle to repay any new debt. This can cause your credit score to drop.
It’s recommended that you try to keep your credit usage below 30% of your total credit limit.

Taking out new credit
If you’ve taken out new credit, you might be surprised to see your credit score has dropped. There are two reasons why this can happen:
When you apply for credit a lender will carry out a ‘hard search’ or a ‘credit application search’ on your report. This type of search is recorded on your report and it can negatively affect your credit score and report. If you’ve applied for several lines of credit in a short space of time, this may further impact your score. This is because it can give the impression to lenders you’re too eager for credit, which may put them off. (That’s why you may wish to use an eligibility checker, such as the one from ClearScore (a credit broker, not a lender), before applying for credit).
When you take out a new line of credit the average age of your credit accounts will decrease. This may cause your score to go down as lenders tend to prefer seeing older credit accounts. This is because this behaviour suggests stability, which helps prove to lenders that you're a reliable borrower, and a lower credit risk. Once your account gets older and the average credit age on your report goes back up, your credit score may begin to recover, though this depends on your overall credit profile. So, applying for credit can cause your score to drop slightly at first. However, if you pay back your bills on time and in full, and keep your credit usage in check, your credit score may recover over time, though individual results will vary depending on your wider credit profile.
Settling a financial agreement in court
If you declare yourself legally bankrupt or are issued with a County Court Judgement (CCJ) or an IVA (Individual Voluntary Arrangement) it can significantly harm your score. This is because it tells lenders you have failed to repay debt in the past, and you might be a risky person to lend to.
Closing an old account
If you’ve recently closed an account, your score might drop. If the account was quite old, then closing it can cause the average age of your accounts to fall. Sometimes your score may follow suit. Closing an old account can also mean you have less credit available overall. If, by closing the account it pushes your credit usage over the 50% level, then it could negatively impact your score.
Moving address regularly
Lenders may see frequent address changes as a sign that you're not in a particularly stable position. Lenders prefer to see stability as it can imply that you'll be more likely to pay them back. So, if they see something on your report that suggests the opposite, it can affect your score.
Why has my credit score gone down when nothing has changed?
Sometimes your credit score drops even though you haven't missed a payment, opened a new account, or done anything differently. This can be frustrating, but there are several behind-the-scenes reasons why your credit score may have gone down without any obvious change on your part.
Can my credit score drop without me doing anything new?
Yes, it can. Your credit score is calculated from a wide range of data points, and not all of them are within your direct control. Changes made by lenders, updates to scoring models, and the natural ageing of information on your report can all trigger a drop - even if your own financial behaviour hasn't changed at all.
Could a lender reducing my credit limit cause a score drop?
Absolutely. If a lender decides to lower your credit limit - something they can do at any time - your credit utilisation ratio increases automatically, even though you haven't spent a penny more. For example, if you owe £500 on a card with a £2,000 limit, your utilisation is 25%. If the lender cuts your limit to £1,000, that same £500 balance now represents 50% utilisation, which could push your score down.
Does old positive information falling off my report lower my score?
It can. Credit reference agencies typically hold account data for six years. When a well-managed, long-standing account drops off your report because it's reached that six-year mark, you lose the positive history it was contributing. This can reduce the average age of your accounts and remove evidence of reliable repayment, both of which may cause a dip in your score.
Can changes to the CRA scoring model itself cause a drop?
Yes. Credit reference agencies such as Equifax periodically update the algorithms they use to calculate scores. When a scoring model is recalibrated, the way certain data points are weighted can shift. This means your score could change even though the underlying information on your report is exactly the same. These updates are usually designed to improve accuracy, but they can produce short-term fluctuations.
Could a joint account holder's behaviour affect my score?
If you hold a joint credit agreement - such as a joint mortgage, joint loan, or joint account with an overdraft facility - with another person, you become financially linked to them. A basic joint bank account without a credit facility does not automatically create this link. If a financially linked person misses payments, takes on excessive debt, or defaults on an account, their negative activity can reflect on your report and pull your score down. If you're no longer financially connected to someone, it's worth asking the CRA to remove the financial association from your report to prevent their behaviour from continuing to affect you.
How much your score changes depends on the overall picture of your credit report
Credit scoring isn’t one size fits all. The impact of certain changes to your report will have a different effect for everyone. The impact on your score will depend on what your report looks like as a whole.
So if you miss a payment but have a good credit history, it’s not likely to lower your score significantly. However, if you have a history of managing your debt poorly it could have a bigger impact.
How long does a credit score drop last?
The length of time a credit score drop lasts depends on what caused it. Some impacts are short-lived and resolve within a few months, while others can stay on your report for years. The table below gives an approximate recovery timeline for each of the common causes covered in this article.
Cause of drop | Typical time on report | Estimated score recovery window | What you can do to speed it up |
|---|---|---|---|
| Cause of drop Late or missed payment | Typical time on report Up to 6 years | Estimated score recovery window 12-24 months for significant recovery | What you can do to speed it up Bring the account up to date immediately and maintain a clean payment record going forward. |
| Cause of drop Default (arrears) | Typical time on report 6 years from the default date | Estimated score recovery window Impact lessens gradually; strongest recovery after the default drops off | What you can do to speed it up Settle the outstanding balance if possible and avoid further missed payments on other accounts. |
| Cause of drop High credit utilisation spike | Typical time on report Updated monthly | Estimated score recovery window 1-2 months once balances are reduced | What you can do to speed it up Pay down balances to below 30% of your total credit limit as quickly as you can. |
| Cause of drop New credit application (hard search) | Typical time on report Up to 12 months (visible for longer but impact fades) | Estimated score recovery window 3-6 months | What you can do to speed it up Avoid applying for further credit in the short term; use eligibility checkers instead. |
| Cause of drop CCJ, IVA, or bankruptcy | Typical time on report 6 years (bankruptcy can be longer) | Estimated score recovery window Gradual improvement, with the biggest recovery once the entry is removed | What you can do to speed it up Keep all other accounts in good standing and seek professional debt advice if needed. |
| Cause of drop Closing an old account | Typical time on report Account data stays for up to 6 years | Estimated score recovery window 6-12 months as remaining accounts age | What you can do to speed it up Keep your oldest accounts open where practical and monitor your credit utilisation ratio. |
| Cause of drop Frequent address changes | Typical time on report Address history is ongoing | Estimated score recovery window Improves as time at your current address increases | What you can do to speed it up Register on the electoral roll at your current address as soon as you move. |
Factors that can speed up or slow down recovery
Your overall credit profile plays a big role. If you have a long history of managing credit well, a single negative event is likely to recover faster because the rest of your report paints a positive picture. On the other hand, multiple negative marks close together can compound the damage, making recovery slower. Consistently paying bills on time, keeping balances low, and avoiding unnecessary credit applications are the most reliable ways to accelerate your score's recovery.
Should I worry about my score changing?
If your score has dropped by a large amount it’s worth double checking all the information in your report is showing correctly. If you notice any errors, you can report them straight to Equifax.
If you have noticed a minor score drop, it may be useful to wait and see how your score changes over the next 1-2 months. This will let you see whether this is the start of a downward trend. Alternatively, you may find your score goes back up in the following months.
It might not be a famous saying, but what goes down can go back up. A decrease in your score doesn't have to be permanent. Check out our list of ways to improve your credit score, or you may wish to try our personalised Coaching programmes, so you can start working to build it back up again.

How to check why your credit score dropped
If your credit score has gone down and you're not sure why, working through these steps can help you pinpoint the cause and decide what action to take.
Step 1: Review your ClearScore timeline for recent changes
Log in to your ClearScore account and look at your score timeline - checking your score won't affect it, as it's a soft search only visible to you. Compare your current score with previous months to identify exactly when the drop occurred. This helps you narrow down which reporting period introduced the change, making it easier to match the drop to a specific event.
Step 2: Look for new hard searches you don't recognise
Check the searches section of your credit report for any hard searches (credit application searches) that you didn't initiate. An unfamiliar search could indicate that someone has applied for credit in your name, or it may be a legitimate search you've forgotten about - such as a mobile phone contract or a car finance application.
Step 3: Compare your credit utilisation month-on-month
Look at your credit card balances relative to your credit limits. Even if you haven't spent more than usual, a lender may have lowered your credit limit, which would push your utilisation ratio higher. Aim to keep your overall utilisation below 30% of your total available credit.
Step 4: Check for errors or accounts you don't recognise
Scan your full report for any information that looks incorrect - wrong addresses, accounts you didn't open, or payments marked as missed when you know they were made on time. If you spot an error, you can report it directly to the associated credit agency to have it investigated and corrected.
Step 5: Monitor your score over the next 1-2 months
If you can't find an obvious cause, give it a little time. Minor fluctuations are normal and your score may recover on its own within the next couple of reporting cycles. Set up score change alerts in your ClearScore account so you're notified of any further movements, and revisit your report after 30-60 days to see whether the trend is continuing or has reversed.
