UK-wide. The discrimination rules referenced are those introduced in England by the Renters’ Rights Act.

The short version

You can run a credit check on a prospective tenant, but only with their explicit consent, and you must tell them who is doing it and why. What it usefully shows is county court judgments, bankruptcies and insolvency arrangements — hard facts that predict something. What it shows less usefully is a score, which mostly measures borrowing history and penalises people who have never needed credit. A 23-year-old with no debt and a thin file is not a risk; a CCJ from last year is. And whatever you find, the check must be run on the same terms for everyone, because applying it selectively is discrimination.

What the check actually shows

What comes backHow much it tells you
County court judgmentsA lot. An unsatisfied CCJ for a debt is the single most useful item on the report. Stays for six years.
Bankruptcy, IVA, debt relief orderA lot. Relevant, and worth discussing rather than refusing on reflexively.
Electoral roll and address historyUseful for confirming identity and picking up gaps
Existing credit commitmentsUseful for affordability — large monthly commitments reduce what is available for rent
Payment history on those accountsModerately useful. A pattern of missed payments is a signal.
The score itselfLess than people think. It measures credit behaviour, not rent behaviour, and it punishes thin files.
Previous rent payment historyNot included. Rent is not routinely reported to credit agencies, which is the fundamental limitation.
That last row is why a previous landlord reference outperforms a credit check as a predictor of arrears. The credit file tells you how someone handled borrowing; only the landlord tells you how they handled rent.

Consent and data protection

A credit check is processing personal data, and a hard search leaves a footprint on the applicant’s file. Three things you must do:

  1. Get explicit consent, in writing, before you run it. A tick box buried in an application form is weak; a clear, separate statement is better.
  2. Tell them who will run it — the agency or referencing provider — and what you will use it for.
  3. Collect only what you need, and delete unsuccessful applicants’ data once the decision is made. Keeping a folder of rejected applicants’ credit reports indefinitely is a data protection problem with no upside.

Applicants are entitled to know what came back, and to see their own file and correct errors. Errors are common enough that a flat refusal without telling someone why is both unfair and, in practice, a way of losing good tenants to a mistake.

You pay for it. Charging a tenant for referencing or credit checking has been a prohibited payment since the Tenant Fees Act 2019, and an “admin fee” covering the same thing is caught. The cost of assessing risk is a cost of letting.

Using the result lawfully

Since 1 May 2026 it has been unlawful in England to refuse an applicant because they receive benefits or have children, or to apply different terms to them. That has a direct effect on how you use a credit check:

  • Run the same check on every applicant. Not just the ones you have doubts about.
  • Apply the same threshold to every applicant. Write it down before you advertise.
  • Do not require a guarantor only from some groups. Requiring one from everyone who fails the same affordability test is lawful; requiring one from benefit claimants is not.
  • Assess affordability on all household income, including benefits. See the ban on benefit discrimination.
  • Record the reason for every decline. A decision you cannot explain later looks like the decision the law prohibits.

What to do with an imperfect file

What you findSensible response
Thin file, no adverse dataUsually fine. Common for young people, recent arrivals and those who avoid credit. Lean on income and landlord references instead.
Old satisfied CCJAsk about it. A judgment from four years ago, paid, with clean references since, is a story rather than a risk.
Recent unsatisfied CCJA genuine concern. Consider a guarantor, and be consistent about when you require one.
Current bankruptcy or IVADiscuss it. An IVA with regular payments and stable income can be a better prospect than an unmanaged mess.
Address history gapsAsk. There is usually an ordinary explanation — living abroad, living with family, a period in hospital.
Identity mismatchResolve before proceeding. This is the one to take seriously.
The pattern here is the same throughout: ask rather than assume, apply the same standard to everyone, and write down what you decided and why.

Can I run a credit check without asking?

No. You need the applicant’s explicit consent, and they are entitled to know who is running it and why.

Can I charge the tenant for it?

No. It has been a prohibited payment since the Tenant Fees Act 2019, including where it is dressed up as an admin fee.

Is a low credit score a good reason to refuse?

It can be, if you apply the same threshold to everyone. But a score is a poor predictor of rent payment and punishes people who have simply never borrowed.

Does the report show missed rent payments?

Usually not. Rent is not routinely reported to credit reference agencies, which is why a previous landlord reference is worth more.

How long do I keep the report?

For successful applicants, as long as you need it and no longer. For unsuccessful ones, delete it once the decision is made.

Can I ask a benefit claimant for a guarantor?

Only if you require one from everyone who fails the same affordability threshold. Applying it selectively is unlawful discrimination.
