How UK Credit Reports and Scores Work, and How to Check Yours

Your credit report is the record lenders look at before they say yes or no. Here is who holds it, what is in it, how to get it for free and what to do if something is wrong.

Before a bank, card provider or mobile network agrees to lend you money, it usually looks at your credit history. That history is held in a file about you, and most people have never seen it. Many assume it is a single number, that there is one central record, or that checking it costs money or damages their chances. None of those things is quite true.

This guide explains how credit reports and credit scores work in the UK: who holds your file, what is in it, how to get a copy for free, how lenders turn it into a decision, and how to put mistakes right. It draws on the Information Commissioner’s Office (ICO) and Citizens Advice.

In short

  • Credit reference agencies (CRAs) hold information about your borrowing and finances. The ICO names the three main consumer agencies as Equifax, Experian and TransUnion.
  • You have a right to see your file. It is called a statutory credit report, and it is free.
  • Lenders are not required to report to every agency, so your three files can differ.
  • A credit score is not the same as a report. Citizens Advice says “different lenders use different systems”, so there is no single score that every lender sees.
  • Mistakes can be corrected, but who you contact depends on where the error came from.

What is a credit report, and who holds it?

A credit report is a record of how you have handled credit and certain other financial commitments. Credit reference agencies collect this information so that lenders can judge the risk of lending to you. The ICO explains that the agencies hold records on most UK adults, including credit history, addresses and public records, and give lenders information to help them decide whether to offer you credit.

The ICO identifies the three main consumer agencies as Equifax, Experian and TransUnion. There is an important detail here: there is no legal requirement for lenders to report to all three. Each lender chooses which agency, or agencies, it works with. That means the file at one agency may include information the others do not, and a lender might check only one of them.

For you, the practical lesson is that one clean report does not guarantee the others are clean. If you are checking your credit position, it is worth looking at all three.

What is in your credit file?

According to the ICO, a credit file typically contains:

  • details of credit accounts, such as loans and credit cards,
  • details of utility accounts,
  • previous addresses,
  • electoral roll data,
  • county court judgments,
  • bankruptcy information, and
  • fraud indicators.

Citizens Advice adds that lenders may also see account payment history, home repossession records, financial associations with other people, such as joint applicants, and records of recent credit searches. Information typically stays on file for six years.

Two of those items surprise people. The first is electoral roll data. Being registered at your current address helps a lender confirm who you are and where you live, which is why keeping your registration up to date is one of the practical steps Citizens Advice recommends. The second is financial associations. If you have a joint account or loan with someone, their financial behaviour can show up alongside yours.

How do you get your credit report for free?

You have a legal right to see what is held about you. The ICO calls the document a statutory credit report, and it is free. The ICO’s advice is to look for the phrase “statutory report” on the agencies’ websites, because no subscription fee applies to it.

You can request it verbally or in writing. If you write, the ICO says your request should include:

  • your full name and any previous names,
  • your current address and any addresses from the last six years, and
  • your date of birth.

The agency must respond within one month of receiving your complete request. It may extend that to three months in certain circumstances, but it must tell you within the first month if it is doing so.

It is sensible to ask each of the three agencies, since each may hold different information. You do not have to pay to see your statutory report, so be cautious about any service that makes you subscribe before you can look.

Credit report vs credit score: what is the difference?

The report is the underlying record. A score is a number a lender, or a service acting on its behalf, derives from that record to judge risk.

Citizens Advice describes how this works in practice. Lenders use credit scoring to assess borrowing risk, and when you apply, “each fact about you is given points” which are totalled into a score. A higher score indicates a more creditworthy applicant. The crucial point is that “different lenders use different systems.” Each lender decides what it values, and what score it will accept.

This has two consequences:

  1. There is no single score that rules your fate. A number shown by a free checking service is an indication, not a verdict, because the lender making the decision uses its own methods.
  2. A refusal is not universal. Citizens Advice notes that being turned down by one lender does not mean you will be refused by another.

In short, your statutory report shows what is on file. Whether that file leads to a yes depends on the lender and its criteria.

What do lenders actually look at?

Putting together the ICO and Citizens Advice lists, lenders tend to look at:

  • whether you are on the electoral roll at your address,
  • your account payment history,
  • any court judgments, bankruptcies or similar public records,
  • any financial associations with joint applicants, and
  • how many recent credit searches appear on your file.

That last point deserves attention. Citizens Advice warns that multiple credit applications leave a visible trail, and “lenders may think you already have lots of borrowing” if you apply to many at once. That can damage your chances. A pragmatic approach is to apply for credit only when you need it, rather than applying to several places in quick succession to see who says yes.

What if there is a mistake on your report?

Errors happen. An old address might be linked to the wrong person, an account might be wrongly recorded as late, or a debt might appear that is not yours. The ICO explains the route to a fix.

Start by contacting the relevant credit reference agency. But there is a catch: if the wrong information came from a lender, you should contact that lender directly. The ICO says “the CRAs cannot amend this data without the permission of that company.” In other words, the agency is the messenger, not the source, and it cannot change what a lender told it unless the lender agrees.

If you have had genuine difficulties that explain a problem on your file, Citizens Advice says you can add a “notice of correction” to explain your circumstances. Lenders may take it into account when they review your file.

It is worth acting early. Because information typically stays on file for six years, an uncorrected error can follow you through several applications.

Practical steps to strengthen your credit position

There are no tricks, but Citizens Advice highlights a few habits that help:

  1. Check you are registered on the electoral roll at your current address.
  2. Correct inaccuracies on your file as soon as you spot them.
  3. Add a notice of correction if there is context a lender should know.
  4. Pay on time, consistently. Citizens Advice names consistent on-time payments as a way to improve your credit profile.
  5. Space out applications. Avoid applying to several lenders at once.
  6. Be aware of financial associations. If you share an account or loan with someone, know that their behaviour can show up on your file.

These are habits rather than quick fixes. A strong record is built over time through steady, boring behaviour.

For a wider view of how borrowing fits into your finances, our guide on how to think about debt explains why different kinds of borrowing deserve different treatment. And a healthy buffer makes missed payments less likely, which is why our piece on building a financial safety net is a useful companion. It also helps to understand the charges on your own accounts, which our look at why bank fees still catch people off guard explains.

What if you have been refused credit?

A refusal can feel like a verdict, but it is better treated as information. Citizens Advice suggests requesting your free statutory credit report from any agency, checking it carefully for errors, and exploring alternatives such as a credit union rather than turning to loan sharks. If the refusal came from information on your file, fixing the underlying issue is likely to help more than simply applying again.

Frequently asked questions

Is the statutory credit report really free?

Yes. The ICO says you can request it from a credit reference agency at no cost, and that no subscription fee applies. Look for the phrase “statutory report” on the agency’s website.

How long does it take to get my statutory report?

According to the ICO, an agency must respond within one month of receiving your complete request. It can extend that to three months in certain circumstances, but it must notify you within the first month.

Do all lenders use the same credit score?

No. Citizens Advice says different lenders use different systems, so your score with one lender can differ from another.

How long does information stay on my credit file?

Citizens Advice says information typically stays on file for six years.

Who do I contact to correct a mistake?

Start with the credit reference agency. If a lender supplied the wrong information, contact that lender, because the agency cannot change that data without the lender’s permission, according to the ICO.

The bottom line

Your credit file is less mysterious than it seems. You have a legal right to see it for free, the main agencies are well known, and most mistakes can be fixed with a few letters or emails. The sensible habit is to check your statutory report from all three agencies periodically, correct anything wrong, stay on the electoral roll, and pay what you owe on time. None of that guarantees a particular outcome, but it puts you in the best position when you do need to borrow.
