Why Has My Credit Score Dropped? The Most Common Causes

You logged in to check your credit score and it's gone down. That sinking feeling is universal — even people with great credit get it. So what happened?

In most cases, the cause is one of a small number of common things, and once you know what it is, you usually know how to fix it. This guide walks through the most frequent reasons a UK credit score drops, what it means and what you can do.

How to find out why your score dropped

Before guessing, look at the actual data. Log in to whichever credit reference agency flagged the change (Experian, ClearScore or Credit Karma) and scan the report itself, not just the headline number.

The most useful things to check:

• Your reported balances on each credit account
• Any payment marked as late or missed
• Any new hard searches in the last month
• Any new accounts or closed accounts
• Your electoral roll status
• Any public records (CCJs, defaults)

Most credit reference agencies now flag specifically what changed since your last update. If yours does, start there. If not, our guide to checking your credit score for free covers what to look for in your report.

You missed a payment

This is the heaviest hitter. A single missed payment on a credit card, loan or mobile phone contract can knock 50-100 points off your score overnight.

It doesn't matter if it was an accident. The credit reference agencies record the data the lender sends, and the lender reports the payment as missed if it wasn't received by the due date.

What to do:

• Pay it immediately to stop the issue escalating
• Set up a direct debit for at least the minimum on every credit account
• If it was a one-off and you have a good track record, call the lender — some will agree not to report the late payment if you ask
• If it does end up reported, accept it and focus on a clean run forward — the impact fades over time

The reason for the direct debit is simple: it removes the possibility of human error. You can't forget to pay something a bank pays automatically.

You applied for too much credit

Each formal credit application leaves a hard search on your file. One or two is nothing. Several in a short period adds up — and the cumulative effect can be a noticeable drop in your score.

This catches people out particularly when:

• They're shopping for a new credit card and apply to several
• They're rate-shopping for a loan without using soft-search checkers
• They've been declined and immediately reapplied elsewhere
• A mortgage broker accidentally ran multiple hard searches

Each hard search lasts on your file for 12 months, though most of the impact fades within three to six months. There's no quick fix — you just have to wait it out and avoid further applications during that time. Our guide to improving your credit score covers the broader picture.

Your credit utilisation went up

If you spent more on a credit card than usual this month and the higher balance was on the card when the issuer sent its monthly snapshot to the credit reference agencies, your utilisation looks worse — and your score reflects that.

Critically, this happens even if you intend to pay the full balance off when the statement arrives. The credit reference agencies see the snapshot, not your intent.

The fix:

1. Find your statement date on the affected card
2. Pay the balance down to a low amount a few days before the next statement date
3. That low balance gets reported next month, and your score should recover within a single reporting cycle

You closed an old account

Closing a credit card can drop your score in two ways:

• It reduces your total available credit, so the balances on cards you still use push utilisation higher
• It shortens your average credit history (especially if the closed card was old)

The effect is usually modest but noticeable. If you closed an account thinking it would help your score, that's a common misconception — see our credit utilisation guide for why an open, well-used card usually serves your score better.

If the card you closed was reported as "closed by lender" rather than "closed by you", that's even worse — it suggests the lender ended the relationship, which lenders look at unfavourably.

You have a new CCJ or default

A new County Court Judgement or default landing on your file is one of the most serious drops you can experience. These are very visible to lenders and stay on your file for six years.

If you didn't expect this:

• Find out exactly which debt triggered it
• Check the dates and amounts — sometimes the report is incorrect or out of date
• If you've already paid the debt, get the default updated to "satisfied" (this looks better to lenders, even though it doesn't remove the mark)
• Consider disputing if the default is incorrect — disputes are free
• If you didn't know the debt existed, that could be identity fraud — investigate urgently

For a CCJ, you may also have the option of paying the judgement in full within 30 days — which removes it from your credit file entirely. This is sometimes called the "30-day rule".

Electoral roll changes

Your electoral roll status affects your score. If you've recently moved house and haven't re-registered at your new address, the electoral roll record at your old address eventually drops off — and you appear to lenders as harder to verify.

The fix is the easiest one on this list: register at gov.uk/register-to-vote. It takes five minutes. You don't have to vote — being on the register is what matters. Most people see the change reflected on their credit file within a few weeks.

Identity fraud on your file

A sudden, unexplained sharp drop in your score — especially if it comes with new accounts or hard searches you don't recognise — can be a sign of identity fraud. Someone has opened credit accounts in your name.

If you suspect this, act quickly:

1. Contact the credit reference agencies and ask for a fraud alert on your file (free)
2. Report the fraud to Action Fraud (actionfraud.police.uk)
3. Contact CIFAS to add a protective registration to your file
4. Contact each fraudulent creditor to dispute the accounts
5. Get the fraudulent accounts and searches removed via the dispute process

Identity fraud can be cleaned up, but it takes work. The earlier you catch it, the easier it is. Checking your credit file monthly is the simplest defence.

A credit account was opened in error

Sometimes a credit account shows up on your file that's genuinely not yours — and not the result of fraud. Common causes:

• Someone with a similar name had their data added to your file by mistake
• A lender misreported a closed or rejected application as an open account
• A joint account ended and one party was incorrectly recorded as still owing

If you find an account on your file you didn't open, dispute it with the credit reference agency. The dispute is free, the investigation has to complete within 28 days, and if the account isn't yours, it has to be removed.

How long until my score recovers?

Depends on what caused the drop. Rough timeline:

• High utilisation snapshot: 1-2 months once you pay it down
• Missed payment: 6-24 months for most of the impact to fade; six years for the mark to drop off entirely
• Cluster of hard searches: 3-12 months
• Closed old account: Slow gradual recovery; never fully reverses if the closed history was significant
• CCJ or default (unsettled): 3-6 years of weight; six years to drop off
• CCJ or default (settled): Some immediate improvement; six years to drop off
• Electoral roll re-registration: 1-2 months
• Identity fraud cleanup: 1-6 months depending on speed of investigation

The faster you act on what caused the drop, the faster recovery starts. Our credit improvement guide covers the broader recovery toolkit.
