UK Credit Reference Agencies Explained
Unlock the secrets behind your credit score and discover how the UK's three major agencies shape your financial reputation and borrowing power.
Learn about Experian, Equifax, and TransUnion, and how credit reference agencies impact your financial profile.
Have you ever wondered where lenders get the information to approve or decline a credit application? The answer lies with a handful of powerful companies known as Credit Reference Agencies (CRAs).
These agencies are the keepers of your financial history. Understanding the role of credit reference agencies is the first step toward taking control of your credit profile. This guide explains who the main players are in the UK, what they do, and how their data shapes your financial life.
What Are Credit Reference Agencies?
A Credit Reference Agency (CRA), also known as a credit bureau, is a private company that securely collects, stores, and shares information about how individuals manage credit and bills.
Lenders (like banks and credit card companies) report your financial behaviour to these agencies every month. In return, when you apply for a new product, the CRAs allow lenders to review your credit history to assess your reliability as a borrower. This data is what they use to calculate your credit score.
The Three Main Credit Reference Agencies in the UK
The UK credit reporting market is dominated by three major agencies: Experian, Equifax, and TransUnion. While they all do a similar job, they are separate companies and the information they hold can differ.
Experian
Experian is one of the largest and most widely used CRAs in the UK.
- Scoring System: Their credit score is calculated on a scale of 0-1250. A higher score indicates a lower risk to lenders.
- Lender Use: Many of the UK’s major banks, mortgage providers, and credit card companies use Experian data to make lending decisions.
Equifax
Equifax is another global player with a strong presence in the UK.
- Scoring System: Their score is calculated on a scale of 0-1000. Like Experian, a higher score is better.
- Partnerships: Different lenders have commercial partnerships with different CRAs. Many well known banks and utility companies rely on data from Equifax.
TransUnion
Formerly known as Callcredit in the UK, TransUnion is the third major agency.
- Scoring System: Their score is calculated on a scale of 0-710.
- Unique Features: While used by traditional banks, TransUnion is also popular with newer fintech lenders and is often used for identity verification and tenancy referencing.

What Information Do CRAs Hold?
All three agencies collect similar types of information to build your credit report.
This includes:
- Personal Details: Your name, date of birth, current and previous addresses.
- Credit Accounts: A list of your credit cards, loans, mortgages, overdrafts, and some bill accounts (like mobile phones) from the last six years.
- Repayment History: A monthly record of whether you paid on time, were late, or missed payments for each account.
- Public Records: Information like County Court Judgements (CCJs), bankruptcies, and Individual Voluntary Arrangements (IVAs).
- Credit Applications: A record of any “hard searches” made when you formally applied for credit.
How Lenders Use CRA Data
Understanding how lenders use credit data is key. They don’t just look at the three digit score; they analyse the details in your report.
- To Assess Risk: Your payment history shows them how reliable you have been in the past.
- To Determine Eligibility and Rates: The information helps them decide whether to approve your application and what interest rate to offer you. A stronger report usually means a better rate.
- Why Results Vary: A lender might only check your report with one or two CRAs. If there’s an error on your Equifax report, a lender who only uses Equifax might decline you, while a different lender who uses Experian might approve you.
How to Check Your Credit Reports
It’s vital to check your report with all three agencies regularly.
- Free Statutory Reports: Under UK law, you are entitled to a free statutory credit report from each of the three CRAs.
- Check Each One: Because the data can differ slightly between them, checking all three ensures you have a complete picture of your financial profile.
- Dispute Errors: If you find a mistake-like an incorrect address or a settled account showing as active-you have the legal right to raise a dispute with the CRA to have it investigated and corrected.

Frequently Asked Questions
Do all lenders use the same credit reference agency?
No. Most lenders have partnerships with one or two main agencies they use for applications. Very few use all three.
Why is my score different between Experian, Equifax, and TransUnion?
There are two reasons. First, some of your lenders may only report to one or two of the agencies, so the underlying data they hold on you might be slightly different. Second, each agency uses its own unique algorithm to calculate your score from that data.
How often is my credit report updated?
Lenders typically send updates to the CRAs once a month. This means your report will usually be updated every 30-45 days.
