Tenancy Setup & Management
Tenant referencing: a landlord's guide
Tenant referencing is the process a landlord uses to confirm that a prospective tenant is who they claim to be, can afford the rent, and has a reliable renting history. Sometimes called a tenant background check, it combines identity verification, a credit check, income and employment verification, a previous landlord reference and the mandatory Right to Rent check into a single evidence-based picture of an applicant before a tenancy is offered. It is the last point at which a landlord has full control over who lives in their property, and since Section 21 was abolished on 1 May 2026 it is also the most consequential.
Why the decision carries more weight now
Removing a tenant now means establishing a Section 8 ground and going through the courts, a slower and more expensive route than the no-fault notice it replaced. The practical consequence is that tenant selection has become the main risk control a landlord still holds, and the quality of the referencing decision now determines how the whole tenancy runs. Two other changes reinforce the point. Rent in advance is capped at one month, so a weak applicant can no longer be offset with cash upfront, and it is unlawful to reject applicants because they receive benefits or have children, so the criteria you apply must be written down and applied identically to everyone. The full regime is set out in our Renters' Rights Act hub; what follows is how it changes the referencing process itself.
The six checks
Identity verification confirms the applicant is who they say they are, using a current passport, photocard driving licence, national identity card or biometric residence permit checked against the application. Tenancy fraud has grown with rental competition, so treat reluctance to produce originals, poor-quality scans and mismatched addresses as reasons to pause rather than paperwork to process.
The credit check shows County Court Judgments, insolvencies, defaults and electoral roll registration. What matters is the pattern rather than any single entry: recent, repeated and unresolved problems weigh heavily, while an old settled CCJ alongside strong income and a good landlord reference rarely decides anything. Our guide to credit checking a tenant covers consent, what a soft search does and does not reveal, and what to do when an applicant fails.
Income and employment verification confirms the rent is affordable. The common benchmark is gross annual income of at least 30 times the monthly rent, so a rent of £1,200 a month points to roughly £36,000 a year. Ask employed applicants for payslips, an employment contract and bank statements showing salary, and self-employed applicants for two years of SA302 tax summaries and an accountant's letter. Our rent-to-income calculator runs the test for any rent and household, including joint applicants. Benefit income counts, and must be assessed on the same basis as any other income.
The previous landlord reference, also called a residential reference, is a statement from the applicant's current or most recent landlord confirming the dates of the tenancy, whether the rent was paid in full and on time, the condition the property was left in, and whether they would let to the applicant again. It is the only check that describes actual tenancy behaviour rather than financial circumstance, which is what makes it the most informative and the most often faked. Verify that the referee genuinely owns the property before you weigh a word of it. Our questions to ask a former landlord gives you the script for the call, and our landlord reference letter templates cover the written route.
The Right to Rent check is the only component that is a legal obligation, required in England under the Immigration Act 2014 for every adult who will occupy the property as their main home, and it must be completed before the tenancy begins. British and Irish citizens can be checked against a passport; most other applicants are verified in real time through the Home Office online service using a share code. Penalties reach £10,000 per occupier for a first breach and £20,000 for repeat breaches, with criminal liability for knowingly letting to someone without the right to rent, as set out in the GOV.UK right to rent code of practice. Our guide explains how to carry out a Right to Rent check in full. Because tenancies are now periodic with no fixed end date, follow-up checks for occupiers with time-limited permission continue through the tenancy rather than only at renewal.
Address history covers three to five years and exists to be cross-checked against everything else. Inconsistency between the addresses the applicant gave you and those the credit agencies hold is one of the more reliable early markers of application fraud, and it is worth resolving before you spend money on anything further.
What you can and cannot charge
Under the Tenant Fees Act 2019 you cannot charge a tenant for referencing, credit checks, administration, guarantors, inventories or check-in. The cost sits with the landlord, and charging a prohibited payment means repaying it within 28 days and facing a penalty of up to £5,000 for a first breach or £30,000 for repeat breaches. What you may still take is set out in our tenant fees entry, chiefly a holding deposit capped at one week's rent, which reserves the property while you reference and starts a 15 day deadline for agreement, and a tenancy deposit capped at five weeks' rent where annual rent is under £50,000.
How long referencing takes
Referencing usually takes two to five working days, and a clean application with responsive referees can complete inside 48 hours. The automated checks return in minutes; it is the employer and the previous landlord who set the pace. Our guide to how long tenant referencing takes breaks down each check, explains what causes delays, and shows how the 15 day holding deposit deadline shapes your window.
When to ask for a guarantor
Students, first-time renters, applicants with variable self-employed income and those without a UK rental history often cannot pass on their own merit, and a guarantor is the usual answer. Reference the guarantor to the same standard as the tenant, including identity, credit and income of around three times the annual rent, and make sure they are UK-based so the agreement can be enforced. Guarantors carry more weight than they used to, precisely because the one-month cap on rent in advance removed the alternative. Their liability continues through the periodic tenancy.
How to reference a tenant, step by step
Take an application covering personal details, employment, income, three to five years of address history, referee contacts and written consent to the checks.
Screen it before you spend anything, resolving obvious inconsistencies first.
Verify identity, checking originals in person or by permitted video method, and record the date.
Complete the Right to Rent check using the correct method for the applicant's status.
Run the credit and affordability checks, applying the same written criteria to every applicant.
Contact the previous landlord directly, using a number you sourced yourself rather than one supplied by the tenant, and confirm they own the property.
Decide, and write down why. No single result is automatically decisive, but several concerns together usually are. Where the picture is borderline, ask for a guarantor rather than more evidence of the same kind.
Store the file securely under UK GDPR, keeping Right to Rent copies for the tenancy plus one year and financial records for six years.
The most common failures are avoidable and consistent: rushing the Right to Rent check, accepting a reference from a friend posing as a landlord, charging a prohibited fee by accident, referencing the tenant thoroughly and the guarantor barely at all, and deciding too quickly to fill a void. A void costs weeks. A tenant who cannot be removed costs months.
Referencing yourself, or paying a service
Both work, and the choice turns on portfolio size. Doing it yourself costs little beyond the credit report, gives you the follow-up questions a standard form never asks, and suits one or two properties. A service returns standardised checks for roughly £15 to £50 per tenant, all paid by you, with stronger fraud detection and automated Right to Rent verification, and earns its cost across a larger or HMO portfolio. Whichever route you take, referencing generates a file you are obliged to keep, and keeping it properly is what protects you if a rejected applicant later questions the decision. August holds consent forms, reports and agreements against the tenancy in document management, and once the tenant moves in, Open Banking rent tracking records every payment as it lands, which is the evidence the next landlord will ask you for.
Frequently asked questions
What is tenant referencing?
It is the process a landlord uses to confirm that a prospective tenant is who they say they are, can afford the rent, and has a reliable renting history, combining identity, credit, income, previous landlord and Right to Rent checks into a single assessment before a tenancy is offered.
How long does tenant referencing take?
Usually two to five working days, and often inside 48 hours for a clean application. Delays nearly always come from waiting on an employer or a previous landlord, so gather documents and referee contacts up front.
Can a landlord charge a tenant for referencing?
No. Referencing and credit check fees are prohibited payments under the Tenant Fees Act 2019 and the landlord pays. You may still take a holding deposit of up to one week's rent while the checks are completed.
Can you refuse a tenant because they receive benefits?
No. Since 1 May 2026 it has been unlawful to reject an applicant because they receive benefits or have children. Assess every applicant against the same written affordability and reference criteria, and where income is borderline, consider a guarantor rather than a blanket rule.
What happens if a tenant fails referencing?
You can decline, or you can ask for a guarantor. What you cannot do is take several months' rent in advance to compensate, because rent in advance is capped at one month. Whichever you choose, record the criteria you applied. If you want every referencing record and compliance date in one place, you can start with August for free.
Final thoughts
Referencing is a short process with a long shadow. Run all six checks, apply the same written criteria to every applicant, verify the previous landlord before you trust the reference, and do not let a looming void push you into a decision you cannot reverse. Since 1 May 2026 the shortcuts have gone and the cost of getting it wrong has risen, which makes the few days spent on evidence the cheapest few days in the tenancy.
