What does a tenant credit check actually show?
Less than most landlords expect in one direction, and more in another. A credit check is an excellent identity and adverse-historyfilter. It is not a character reference, an income verification, or a criminal record check — and it will almost never tell you that someone owed their last landlord three months' rent.
What it does show
Identity and address history
Confirms the applicant is who they say they are and has lived where they claim, usually via the electoral roll and linked addresses. Quietly the most valuable part of the report — it is the bit that catches a made-up identity.
County Court Judgments (CCJs)
Amount, date, and whether satisfied. A CCJ stays on file for six years. Recency and whether it has been paid matter far more than its existence.
Defaults
Accounts a lender has closed as unpaid. Also six years on file. A cluster of recent defaults says more than one old one.
Bankruptcies, IVAs and other insolvency
Taken from the Individual Insolvency Register. An active IVA means committed monthly payments that reduce what is genuinely available for rent.
Credit accounts and how they're run
Open accounts and payment conduct. Consistently meeting commitments is a better signal than a headline number.
Anti-money-laundering and sanctions screening
PEPs and sanctions lists, depending on the product. Rarely relevant to an ordinary let, but cheap to include.
What it doesn't show
This half matters more, because it is where landlords assume coverage they don't have.
A criminal record
Nothing on a credit file relates to criminal convictions. Only a DBS check covers that, and a landlord has no lawful basis to demand one for an ordinary tenancy.
Current income
A credit file shows commitments, not earnings. Verifying income needs payslips, an employer reference, SA302s for the self-employed, or Open Banking — which is what a full reference adds.
Immigration status or right to rent
A separate legal duty in England with its own methods and its own penalties. A credit check does not discharge it.
Whether a previous landlord would house them again
Rent is not reported to credit bureaux by default, so a tenancy can run for years in arrears and leave no trace on the file. Only a landlord reference covers this.
A single universal 'credit score'
There isn't one. Scores are calculated differently by each bureau and each lender, so the number an applicant quotes from an app is not what a referencing provider is assessing.
The rent-arrears blind spot
It is worth dwelling on one of those, because it surprises people. Rent is generally not reported to credit reference agencies. A tenant can fall months behind, be chased, leave owing money, and arrive at your property with a perfectly clean credit file — unless the previous landlord went as far as obtaining a CCJ, which most never do.
So a clean credit check is genuinely good news about how someone handles lending, and close to silent about how they handle rent. The only reliable cover for that gap is a previous-landlord reference obtained independently — not a phone number the applicant supplies, which may belong to a friend.
How to read a result sensibly
Judge adverse entries on recency, size and pattern, not on presence. A satisfied £200 CCJ from four years ago tells you almost nothing. An unsatisfied £4,000 CCJ from three months ago, or four defaults inside a year, tells you a great deal. An active IVA means committed monthly payments that reduce what is genuinely available for rent, whatever the headline income says.
And ask. Applicants with a clean explanation — a business that failed, a relationship breakdown, a disputed mobile contract — are usually willing to give it, and the answer is often more informative than the entry itself.
Credit check or full reference?
A £9 credit check covers identity, address history and adverse credit — proportionate for a lower-risk let, and a sensible first filter before spending more. A £19 full reference adds the things the credit file cannot reach: income and affordability verification, an employer reference, an independently obtained previous-landlord reference, Right to Rent in England, and anti-fraud checks.

FAQ
Does a tenant credit check affect the applicant's credit score?
No. Referencing searches are soft searches. They are recorded on the applicant's file so they can see them, but they are not visible to lenders and do not affect their score. This is worth telling applicants up front — the fear that a check will damage their rating is a common reason people hesitate to apply.
Do I need the tenant's permission to run a credit check?
Yes. You need their explicit, informed consent before a check is run, and you should keep a record of it. Our free application form collects that consent as its final section so it is on file before you order anything.
How far back does a credit check go?
Six years for the main adverse markers — CCJs, defaults, bankruptcies and IVAs all drop off the file after six years, whether or not they were satisfied. Address history typically goes back further. Anything older than six years simply will not appear, which is why an applicant can be honest about a past problem the report no longer shows.
Does a credit check show rent arrears with a previous landlord?
Almost never. Rent payments are not routinely reported to credit reference agencies, so a tenant can accumulate serious arrears without it ever touching their credit file — unless the landlord obtained a CCJ, which most do not. This is the single biggest blind spot in a credit-only check, and the reason a previous-landlord reference is worth having.
Is a credit check enough on its own?
It depends what you are protecting against. A credit check is a strong identity and adverse-history filter for £9, and for a low-risk let it is often proportionate. What it cannot tell you is whether the income is real or whether the last landlord would take them back — both of which are what a full reference adds for £19.
What counts as a serious result?
Judge by recency, size and pattern rather than presence. An unsatisfied CCJ from the last twelve months, a cluster of recent defaults, or an active IVA are all material. A single satisfied CCJ from five years ago usually is not. Ask the applicant for the context before deciding — people with a clean explanation are generally willing to give it.
Can I charge the tenant for the credit check?
No. Under the Tenant Fees Act 2019 charging a tenant for referencing is a banned fee in England. The landlord or agent pays.
