Tenant vetting

Tenant vetting, also called tenant referencing, is the process a landlord runs before granting a tenancy to assess whether a prospective tenant is suitable, affordable, and legally entitled to rent in the UK. It typically combines identity and immigration checks, affordability assessment, reference checks, and a mandatory right to rent check. Where a tenant cannot meet the affordability threshold alone, guarantors are sometimes used as additional security.

Good vetting protects the landlord from rent arrears and anti-social behaviour by selecting tenants who can sustain the tenancy over the long term. With Section 21 abolished since 1 May 2026, this matters more than ever: the ability to remove a non-paying or disruptive tenant now depends entirely on establishing grounds under Section 8, a process that takes months. Thorough upfront vetting is the most cost-effective risk management a landlord has.

What tenant vetting covers

A thorough vetting process typically includes the following:

Identity verification. Confirming the applicant is who they say they are, using passport, driving licence, or other official documents.

Right to rent check. A legal requirement in England under the Immigration Act 2014. Landlords must verify that every adult occupant has the legal right to rent residential property in the UK, either by checking original documents or by using the Home Office online service with a share code. Failure to conduct a valid check can result in a civil penalty. See our right to rent check definition for the full procedure.

Affordability assessment. Checking that the tenant's income is sufficient to sustain the rent. Most landlords and referencing agencies use a rent-to-income ratio, typically requiring gross annual income of 30 times the monthly rent (equivalent to 2.5 times the annual rent). Our rent to income calculator lets you assess this against a specific applicant. Where income falls short, a guarantor who meets the same affordability threshold is commonly requested.

Credit check. A credit history search to identify county court judgments (CCJs), bankruptcy, or a pattern of missed payments that may indicate financial difficulty.

Previous landlord or agent references. Seeking confirmation from prior landlords that the tenant paid on time, looked after the property, and gave proper notice. Our blog article on 15 questions to ask former landlords during tenant vetting provides a ready-to-use framework.

Employment or income verification. Confirming employment status, salary, and stability, including benefit income, self-employment accounts, or pension income where applicable.

Property-specific considerations. For an HMO licence property, or where all-inclusive rent is offered, additional checks around the number of occupants, household composition, or utility usage patterns may be appropriate.

What landlords cannot do: the legal constraints

Vetting must be conducted within a clear legal framework. Two sets of rules are particularly important.

Referencing fees are prohibited. Under the Tenant Fees Act 2019, landlords cannot charge tenants separately for referencing, credit checks, or administrative processing. These are prohibited payments, and charging them risks enforcement action and can also undermine possession proceedings if the landlord has received unlawful payments from that tenant.

Discrimination on grounds of benefits or children is now illegal. From 1 May 2026, the Renters' Rights Act makes it unlawful to refuse a tenancy, discourage an application, or treat a prospective tenant less favourably because they receive housing benefit or other state benefits, or because they have children. GOV.UK's guidance on rental discrimination sets out the rules in detail. A landlord can still apply a consistent affordability test, requiring income to meet a set rent-to-income ratio is lawful, but the test must be applied equally, must account for all income including benefit income, and must not be raised because of a tenant's benefit status or family composition.

The Equality Act 2010 continues to apply separately, prohibiting discrimination on grounds of race, sex, disability, religion, and other protected characteristics throughout the vetting process.

Personal data must be handled lawfully. Vetting involves processing sensitive personal information. Landlords are data controllers under UK GDPR and must have a lawful basis for processing, retain data only as long as necessary, and handle it securely.

Consistency and record-keeping

Vetting decisions must be consistent across all applicants. Applying stricter criteria to some applicants than others, whether by income threshold, reference depth, or document requirements, can expose a landlord to discrimination complaints. If a rejected applicant raises a complaint through the Private Rented Sector Ombudsman or redress scheme once it is operational, written records of the vetting criteria applied and the decision made will be the landlord's primary defence. August's tenant vetting guide explains how to set up a documented, consistent vetting process.

Frequently asked questions

Why would a tenant fail referencing?

The most common reasons are: income below the rent-to-income threshold (typically gross income below 30x the monthly rent); adverse credit history such as CCJs or a recent default; a poor reference from a previous landlord citing arrears or property damage; inability to verify employment or income; or a failed right to rent check. A guarantor can sometimes address an income shortfall, but cannot remedy adverse credit or a negative landlord reference.

Will I pass tenant referencing?

This depends on the specific criteria the landlord or agency uses, but the main factors are: income sufficient to meet the affordability threshold, a clean credit history, a positive reference from your most recent landlord, and a valid right to rent. If you have concerns about any of these, discussing them openly with the landlord before applying is usually better than allowing a formal check to surface a problem without context.

Can a landlord refuse a tenant on benefits?

Not on grounds of benefit status alone, since 1 May 2026. Refusing a tenancy, discouraging an application, or applying a higher income threshold specifically because a tenant receives benefits is now unlawful under the Renters' Rights Act. A landlord can still require income to meet a standard affordability ratio, but must count benefit income equally alongside earned income, and the same threshold must apply to all applicants.
