There’s no single UK credit score. Lenders look at your credit reports and their own criteria, so understanding your reports matters more than any one number.
Summary
- The three main UK credit reference agencies are Experian, Equifax and TransUnion.
- You have the right to see your statutory credit report from each agency free of charge.
- Lenders use your reports alongside their own criteria, so scores shown by agencies are only a guide.
- Being on the electoral register and paying on time are two of the simplest ways to strengthen your file.
When you apply for a loan, credit card, mortgage or even some phone contracts, lenders check your credit history. In the UK that history is held by credit reference agencies, and knowing how they work helps you keep your file accurate and strong.
The three agencies
- Experian, Equifax and TransUnion are the main UK credit reference agencies.
- Lenders may report to one, two or all three, so your reports can differ.
- Each agency displays its own score, but lenders apply their own criteria.
Seeing your reports for free
You have a legal right to see your statutory credit report from each agency free of charge. Several free services also let you view your report and a score on an ongoing basis.
Top tip
Check all three reports, not just one. A mistake might appear with only one agency, and the lender you apply to may use that agency.
What lenders look at
| Information | Why it matters |
|---|---|
| Payment history | Shows whether you pay on time |
| Credit use | How much of your available credit you’re using |
| Defaults and County Court Judgments | Serious problems that can affect applications for years |
| Applications | Several hard searches in a short time can concern lenders |
| Electoral register | Helps confirm your identity and address |
| Financial associations | Links to people you share credit with |
Building a stronger file
- Register to vote at your current address, if you’re eligible.
- Pay every bill and repayment on time; set up Direct Debits for minimum payments.
- Keep credit card balances well below their limits.
- Space out applications, and use eligibility checkers that use soft searches.
Overdraft use and buy now, pay later plans can also appear on your file; see our guides to overdrafts and buy now, pay later.
Correcting mistakes
- Contact the agency showing the error; it will check with the lender.
- Contact the lender that supplied the information too.
- If something is accurate but has context, you can add a short notice of correction to your report explaining the circumstances.
- If you’re unhappy with the outcome, you can complain to the Financial Ombudsman Service or the Information Commissioner’s Office, depending on the issue.
Take care
Accounts or searches you don’t recognise can be a sign of identity fraud. Contact the lender and the agency straight away, and consider protective registration with Cifas.
The bottom line
Check all three reports regularly, keep your details up to date, pay on time and correct anything that’s wrong. Lenders will see a clear, accurate picture, which is the best foundation for any application.
Questions readers ask
Is there one official UK credit score?
No. Each agency shows its own score, and lenders use their own scoring systems. The information in your reports matters more than any single number.
Does checking my own credit report affect it?
No. Checking your own report is a soft search and isn’t visible to lenders in a way that affects applications.
What is a financial association?
If you have a joint account or joint loan with someone, your credit files may be linked. If you’re no longer financially connected, you can ask the agencies to remove the link.
How long do missed payments stay on my report?
Late payments and defaults generally stay on your credit report for six years.
