Why has my ClearScore credit score dropped?

UKUpdated 6 October 2026 · Written by BuyMeWhiskey Editorial Team · How we check facts

A ClearScore drop means something changed on your Equifax credit report, often a paid-off mortgage or loan, a closed card, higher balances, a lower limit, a new search or an address change; lenders never see the ClearScore number itself, so check the report for errors rather than worrying about the score.

Open your full Equifax report in ClearScore and compare it with last month. Then get your free statutory reports from the other agencies to check for anything wrong.

What your ClearScore number actually is

ClearScore's score runs from 0 to 1000 and is calculated from your Equifax credit report. ClearScore is clear that the number is for your reference only. Lenders don't see it. When you apply for credit, a lender looks at the report data and applies its own scoring, so two lenders can reach different decisions on the same report.

Each credit reference agency uses its own scale: Equifax 0 to 1000, Experian 0 to 999 and TransUnion 0 to 710. A 100-point drop on ClearScore tells you something changed in your Equifax data. It doesn't mean lenders now see you as 10% worse.

The usual reasons a score drops

Higher balances compared with your limits. This is "credit utilisation", and a card that's nearly maxed out counts against you.
A lower credit limit, even if your spending hasn't changed. Equifax lists this as a common cause.
Closing an account. You lose available credit, an active account type and some account history.
Hard searches from credit applications, especially several close together.
Missed or late payments, arrears, defaults or County Court Judgments.
Address or electoral roll changes. Mismatched details make it harder for lenders to confirm who you are.
Mistakes on the report, or an account or search you don't recognise.

Why scores can fall when you owe nothing

It feels unfair, but scores reward evidence that you can handle credit, not the absence of debt. ClearScore points out three things that often catch careful borrowers:

Paying off a mortgage or loan removes a long-running account that showed reliable repayments. Owning your home outright is good for your finances, but it can lower your score.
Clearing your card before the statement date. Lenders report your balance when the statement is produced. If it's already £0, the month can look like no activity at all.
Little or no credit use. Lenders have less recent behaviour to judge you on.

None of these is a black mark. If your report is accurate and has no missed payments, a drop like this is unlikely to matter unless you're about to apply for a big loan or mortgage.

How to find the cause

Open the full Equifax report in ClearScore and compare it with last month. Check balances, limits, closed accounts, new searches, addresses and electoral roll status.
Check the other agencies. MoneyHelper lists four that produce your statutory credit report: Experian, Equifax, TransUnion and Crediva. You have the right to a free copy. The ICO says agencies normally have one month to respond.
Look for financial links. A joint account links you to the other person. After a joint account closes, you can ask the agencies for a "disassociation".

Fixing something that's wrong

The lender or organisation that supplied the data is responsible for correcting it, so ask them first. You can also raise a dispute with the agency. MoneyHelper says an investigation shouldn't take longer than 28 days, and lenders shouldn't rely on the disputed entry meanwhile. Negative information that's accurate usually stays for six years. If there was a reason for it that no longer applies, you can add a Notice of Correction explaining what happened.

Avoid paid "credit repair" firms. MoneyHelper says you can do everything they offer yourself for free.

Pat's credit utilisation with the same £1,000 balance

Worked example

How a limit cut or a closed card moves utilisation, with no new spending. Pat has two cards: Card A with a £5,000 limit and a £1,000 statement balance, and Card B with a £3,000 limit that's never used.

Before: £1,000 ÷ £8,000 total limits = 12.5% utilisation.
Pat closes Card B: £1,000 ÷ £5,000 = 20%. Pat has the same debt, but uses a higher share of the available credit.
Card A's limit is then cut to £2,000: £1,000 ÷ £2,000 = 50%.

ClearScore's own example of high use is £900 owed on a £1,000 limit, which is 90%.

Statement timing: Card A's statement is produced on the 10th and the payment is due on the 30th. If Pat clears the balance on the 5th, the lender reports £0 that month. Paying in full between the 10th and the 30th still costs no interest, and it records a month of borrowing and repaying.

Why did my credit score drop when nothing changed?#

Something in your credit report will have changed, even if your habits haven't. Common causes are a lender updating a balance or limit, an old account closing or being paid off, a search, or an address or electoral roll update. Compare this month's full report with last month's to find it.

Why did my credit score go down after paying off my mortgage?#

Paying off a mortgage removes a long account that showed years of on-time payments, and ClearScore notes this can lower your score. It doesn't mean you're seen as a bad borrower. It reflects less ongoing evidence of repayment, and it's unlikely to matter if the rest of your report is clean.

Does paying my credit card off in full lower my score?#

No, paying in full is good, but timing matters for what gets reported. Lenders report your balance when the statement is produced, so clearing it before then can show £0 and no activity. Paying in full after the statement date but before the due date still avoids interest.

Do lenders see my ClearScore score?#

No. ClearScore says the number is for your reference only. Lenders look at your credit report data and use their own scoring systems, so focus on what's on the report rather than the score.

Why is my ClearScore score different from Experian or TransUnion?#

Each agency uses its own scale and model. Equifax, which ClearScore uses, runs from 0 to 1000, Experian from 0 to 999 and TransUnion from 0 to 710. Not every lender reports to every agency, and updates arrive at different times, so the scores aren't directly comparable.

How do I fix a mistake on my credit report?#

Ask the lender that reported it to correct it, and raise a dispute with the credit reference agency. MoneyHelper says this shouldn't take longer than 28 days, and the entry is marked as disputed meanwhile. If an accurate entry needs context, add a Notice of Correction.

Can someone else at my address affect my credit score?#

Only if you're financially linked, for example through a joint account or joint loan. Simply living at the same address doesn't link you. If a joint account has closed, write to the credit reference agencies to ask for a disassociation, and ask them to investigate any link you think is wrong.
