Question

Why are there three credit reference agencies?

Answer

Because they are competing commercial companies, not a public register. In the UK the three main ones are Experian, Equifax and TransUnion, and each maintains its own separate database.

Why this matters to you:

Lenders do not all report to all three. A lender may report to one, two or all three, at its own discretion — there is no legal obligation to report to any. So an account visible on one file may be absent from another.

Your files will differ, sometimes materially. An error, a default, or a missing account may appear on one and not the others.

Your scores will differ, and they are not comparable. Each agency uses its own scale with different maximum values, so a number from one tells you nothing about another. More importantly, lenders do not use these scores at all — they pull the underlying data and apply their own models. The consumer-facing score is an indication of how your file looks, not a figure any lender sees.

You do not know which agency a lender will use, which is the practical argument for checking all three.

What they hold: electoral roll registration, credit accounts and payment history, credit limits and balances, searches, defaults, county court judgments, bankruptcies and insolvencies, and financial associations with people you have held joint credit with.

What they do not hold: salary, savings, employment details, medical records, criminal convictions, or parking and most council debts.

How to check. All three must provide statutory access to your report, and free services exist from each. Checking your own file is a soft search and has no effect on your rating.

What to do with them: check all three at least annually; dispute errors directly with the agency, which must investigate; add a Notice of Correction to explain circumstances; and remove financial associations with ex-partners, since their credit behaviour can affect your applications.
