Which Credit Report Should You Check for a Mortgage?
Mortgage lenders may use one or more of Experian, Equifax and TransUnion. There is no single report that is always the right one. The useful choice depends on whether a lender has been named, an application has been declined, an account is missing or you are preparing more broadly.
Which credit report do mortgage lenders use?
A lender can choose one or more credit reference agencies, and the choice can vary by lender or application process. If a lender, broker or decline notice identifies an agency, check that report first. If the lender is not yet known, compare the three main reports so that a material difference is less likely to surprise you later.
Start with the report that answers the immediate question
A product ranking is less useful than knowing what you need to confirm. These are the main mortgage-related starting points.
Check the named source first
If an application, agreement in principle or decline identifies Experian, Equifax or TransUnion, start with that report. Check the exact entry, its date and status before deciding what to do next.
Compare the three main reports
If the lender is not known, compare the underlying records rather than the coloured score bands. Look for addresses, financial associations, accounts, public records and searches that differ.
Ask where the provider reports
An account absent from one report is not automatically an error. Ask the bank, lender, utility or other provider which agencies receive its information and compare the dates shown.
Check file matching as well as content
If an agency cannot match you, confirm your name, date of birth and address history. A thin or unmatched file is different from an adverse credit event.
Experian, Equifax and TransUnion hold separate records
The ICO identifies these as the three main consumer credit reference agencies in the UK. They perform a similar role, but the information supplied to each one can differ.
On a phone, swipe sideways to see the full table.
| Agency | What its report can help you check | What it cannot establish |
|---|---|---|
| Experian | The accounts, payment markers, addresses, associations, public records and searches held in Experian’s consumer file. | Its consumer score does not reveal another agency’s full record or guarantee a lender’s decision. |
| Equifax | The corresponding information supplied to Equifax, including its own recorded dates and account coverage. | An account missing from Equifax is not proof that it is absent from Experian or TransUnion. |
| TransUnion | The information in TransUnion’s file and any differences in account reporting, searches or public-record matching. | Its consumer score or band is not a universal mortgage pass mark. |
Check which agency’s data an app or service is showing
A consumer app, monitoring product or multi-agency service can be a route to information. It is not itself evidence that a particular mortgage lender will use the same source.
Statutory report
This is the free route to the information held about your financial standing. You do not have to buy a subscription to exercise that right.
Free app or account
Check the named source agency, which parts of the report are shown, the information date and whether separate eligibility or advertising features are included.
Paid or multi-agency product
Convenience can be useful, but compare current coverage, cost, renewal and cancellation terms. A paid product is not required to obtain the statutory information.
Why can the reports show different information?
A difference can reflect reporting coverage, timing or identity matching. It needs diagnosis before it is treated as an error.
Different data suppliers
A provider may report to one agency, several agencies or none. Ask the provider which agencies it uses if a particular account matters to your mortgage preparation.
Different update dates
Balances and statuses can be supplied or refreshed at different times. Compare the date attached to each entry before disputing a difference.
Different identity matches
Name formats, flat numbers, previous addresses or a recent move can affect matching. Check the personal details alongside the account information.
Use the agency named in the decision before applying elsewhere
A decline is a reason to gather information, not to submit several more applications while the cause remains unclear.
Ask for the main reason
Find out whether the issue relates to credit-reference information, affordability, evidence, the property, product rules or another part of the application.
Identify the agency and search
Ask which credit reference agency was used and whether the footprint was a soft or hard search. Note the application date and lender.
Check the exact record
Review the named report and compare the other two where that would clarify missing, older or inconsistent information.
Apply the same report principle to your mortgage route
The report-selection question is similar, but the context you discuss with an adviser changes.
First-time buyer
Check identity and address matching as well as accounts. A short history or recent move can need a different explanation from missed payments or defaults.
Home mover or remortgage
Check the existing mortgage entry, current commitments and recent searches. A product transfer and an application to a new lender are different decisions.
Self-employed applicant
Personal credit reports do not replace income evidence. Keep the credit record, trading structure and affordability documents as separate parts of the case.
Joint application
Each applicant should check their own reports. Review recorded financial associations without assuming that one person’s stronger score cancels the other person’s history.
How this guide was checked
The selection principles were checked against official or current UK consumer-credit guidance. Lender choices remain case-specific.
ICO credit guidance
The ICO names the three main consumer agencies and sets out why their records can differ. It also suggests starting with one file where appropriate or asking a provider which agencies receive its information. Read the ICO guidance (opens in a new tab).
Agency access routes
Experian, Equifax and TransUnion each publish a statutory-report route. The completed free credit-report access guide (opens in a new tab) keeps those links together.
What stays case-specific
A lender’s chosen agency, search method, scorecard, product criteria and evidence requirements can change. Public guidance cannot confirm which report a future lender will use or whether an application will succeed.
Source links and factual statements checked on 21 September 2026. As the ICO currently labels parts of its credit material as under review, use its live guidance for subsequent changes.
Read current feedback before discussing your report choice
A mortgage conversation can involve sensitive credit information. The live public profile lets you consider how clients describe their contact with Count Ready before deciding whether to enquire.
This guide does not reproduce selected comments, claim a review score or imply that another customer’s outcome predicts yours.
Discuss which record matters to your next step
Tell Count Ready whether a lender or agency has been named, which reports you have checked, the date and type of any relevant entry, and whether you are buying, moving or remortgaging. Do not send passwords, passkeys, complete account numbers, identity documents or full credit reports in the first message.
Speaking with Count Ready cannot establish eligibility, acceptance, a rate or a change to a credit record in advance. Your home may be repossessed if you do not keep up repayments on your mortgage.
Choosing a credit report for a mortgage
Direct answers to the questions customers ask when the three reports or scores do not match.
Which credit report do mortgage lenders use?
A mortgage lender may use Experian, Equifax, TransUnion or more than one agency. The choice can differ by lender and process. Ask the lender or broker which agency and search type will be used rather than assuming one report applies across the market.
Which credit report should I check first?
If a lender, broker or decline notice names an agency, start with that report. If the lender is not known, compare the three main reports. For a specific missing account, ask the data provider which agencies it reports to.
Is Experian more important than Equifax or TransUnion?
No agency is universally more important for every mortgage. A lender chooses which agency or agencies to use, while each report reflects the data supplied to it. The relevant report is the one that answers your current application or record question.
Should I check all three reports before applying for a mortgage?
Comparing all three can reduce the chance of overlooking a material difference when the future lender is unknown. It is not a guarantee of acceptance. If an agency has already been named, prioritise that report and use the others where they add useful context.
Why do my three credit reports show different information?
Providers do not have to report to every agency, and update or identity-matching dates can differ. Check the data source and date before deciding that an entry is wrong. Raise a dispute only where information is genuinely inaccurate.
Does checking my own reports affect a mortgage application?
Checking your own report through a consumer or statutory access route does not create a hard mortgage-application search. Read the service terms carefully and keep a separate record of any eligibility check or credit application you choose to make.
Which report should I check after a mortgage decline?
Ask for the main reason and which credit reference agency was used. Review that report and the relevant search first, then compare the other reports if missing or inconsistent information could affect the next decision.
Do both applicants need to check their reports for a joint mortgage?
Both applicants should check their own reports and recorded financial associations. One person’s stronger consumer score does not remove the other person’s accounts or credit history from a joint assessment.
