How to Improve Your Credit Score in the UK: 10 Practical Steps

By QuidRadar Team · Updated 30 October 2026

Your credit score is a quick summary of how lenders might see you, based on the information in your credit report. There's no single "official" score in the UK. Each credit reference agency uses its own scale (MoneyHelper lists four in the UK: Experian, Equifax, TransUnion and Crediva), and lenders use their own scoring too. But the habits that improve one usually improve them all.

Here are practical steps that make a real difference, starting with the quickest.

Key takeaways

Check your reports with every credit reference agency and fix any errors. Statutory reports are free.

Register on the electoral roll at your current address, if you're eligible.

Pay every bill on time. Payment history is one of the most important factors.

Keep your credit use low compared with your limits.

Avoid lots of hard searches in a short time, and check eligibility first.

Negative markers fade over time. Most stay on your file for six years.

Credit score vs credit report

Your credit report is the record itself: your accounts, balances, payment history, searches, and any defaults or County Court Judgments (CCJs). Your credit score is a number an agency works out from that report.

Lenders don't see the score you see in an app. They look at your report and apply their own criteria, including your income and outgoings. So focus on improving what's in the report. The score will follow.

1. Check your credit reports with every agency

Lenders may use one or more agencies, and the information on each can differ. By law, every credit reference agency must give you your statutory credit report for free, and checking it doesn't affect your score. MoneyHelper also lists free services that give regular access to your report and score through specific agencies.

Look for:

accounts you don't recognise (a possible sign of fraud)
late payments or defaults that are wrong
old addresses or incorrect personal details
people you're financially linked to who shouldn't be there.

2. Correct any mistakes

If something is wrong, raise it with the agency, which will usually check with the lender. If a record is accurate but there's context, for example a missed payment during a hospital stay, you can add a short notice of correction to explain it. Lenders can read this when they check your file.

3. Register on the electoral roll

Being on the electoral register at your current address helps lenders confirm your identity and address. If you're eligible, you can register online at GOV.UK. If you're not eligible to vote (for example, some foreign nationals), you can usually send the credit reference agencies proof of residency instead.

4. Pay everything on time, every time

Late and missed payments are among the most damaging things on a credit file. Set up direct debits for at least the minimum payment on every card and loan so nothing slips through. Then pay extra manually when you can.

This applies to more than credit cards. Loans, mobile phone contracts, and some utility and broadband accounts can all appear on your report.

5. Keep your credit use low

Credit utilisation is how much of your available credit you're using. Owing £900 on a £1,000 limit looks riskier than owing £900 across £5,000 of limits. Paying balances down, and avoiding running cards close to their limit, can help.

Keeping older, unused cards open can also help, because they add to your total available credit. But only do that if you won't be tempted to spend on them.

6. Space out credit applications

Every full application leaves a hard search on your file. Experian says most hard searches stay visible for 12 months (MoneyHelper notes some can remain for up to two years), and lots of them close together can make lenders cautious. Use soft-search eligibility checkers first. See Does Applying for a Credit Card Affect Your Credit Score? and eligibility checkers explained.

7. Break financial links you no longer need

If you've had a joint account or loan with someone, you may be financially associated with them on your report, and their history could be considered when you apply. If you're no longer financially connected, for example after a break-up, you can ask each agency to remove the link.

8. Build a history if you don't have one

A thin file, meaning little or no credit history, can make it hard to be accepted, even if you've never missed a payment. Common ways to start building a history include:

a credit builder credit card used for a small, regular purchase and paid off in full each month (see Credit Builder Credit Cards: How to Build Your Credit Score Safely)
making sure regular bills such as your phone contract are in your name
some services that let you add rent payments to your credit file.

9. Avoid moving too often (or update your details)

A stable address history makes you easier to verify. When you move, update your address with all your lenders and register to vote at the new address promptly.

10. Give it time

Negative information doesn't stay forever. Experian's data retention notice shows that credit account information, including defaults, is used for live lending decisions for six years. Hard searches are visible to lenders for a year. Each month of on-time payments adds a positive record that gradually outweighs older problems.

Things that don't affect your credit score

Checking your own report or score. This is a soft search.
Your salary on its own. It isn't on your credit report, though lenders ask for it when you apply.
Savings and current account balances. These don't usually appear (although some lenders may use Open Banking data if you agree).
Being declined. The decision isn't recorded, only the search.
Your partner's or family's history. Not unless you're financially linked through a joint product.

If you're struggling with debt

If your score is low because you're finding repayments hard, fixing the debt matters more than the number. Free, confidential help is available through MoneyHelper, which can point you to a debt advice service. Talking to your lender early is also important. Under FCA rules, providers must treat customers in financial difficulty fairly.

Frequently asked questions

How long does it take to improve a credit score?

Some changes, like correcting errors or registering to vote, can show up once the agency updates your file. Building a strong payment history takes months of consistent on-time payments.

What is a good credit score in the UK?

Each agency uses its own scale and bands, so a "good" score with one won't be the same number with another. More useful is knowing what's on your report and whether it shows a steady, on-time payment history.

Does paying off a credit card in full improve my score?

Paying in full and on time builds a positive payment history and keeps your utilisation low, both of which are generally seen positively.

Will closing old credit cards help?

Not necessarily. Closing a card reduces your available credit, which can increase your utilisation. If you don't need the card and aren't paying a fee, keeping it open and unused may help. Close it if you're worried you'd overspend.

Do Buy Now Pay Later plans affect my credit file?

Increasingly, yes. BNPL providers can report to credit reference agencies, and new UK rules have brought many BNPL products under FCA regulation. Treat BNPL payments like any other credit commitment and pay on time.

Can I pay someone to fix my credit score?

Be wary of anyone charging to "repair" your credit. You can check your reports and dispute errors yourself for free.
