Tenant Referencing Checks: What Landlords Must Do

Tenant referencing checks verify an applicant's ability to pay rent and meet tenancy obligations. The average UK referencing process takes 3-7 working days. Right to Rent checks are mandatory for all new tenancies in England and carry civil penalties up to £3,000 per illegal occupier.

Landlords use referencing to reduce the risk of rent arrears, property damage and tenancy disputes. A typical check includes credit history, employment verification, previous landlord references and identity documents. Some checks are legal requirements; others are best practice to protect your investment.

What Are Tenant Referencing Checks?

Tenant referencing is the process of collecting and verifying information about a prospective tenant before you sign an assured shorthold tenancy (AST). It confirms their identity, income, rental history and creditworthiness.

Most landlords use one of three routes:

• DIY referencing: You request documents directly from the applicant and contact employers or previous landlords yourself.
• Letting agent referencing: The agent handles checks as part of their tenant-find fee, typically £200-400.
• Third-party referencing companies: Providers like Homelet, Rent4Sure or Vouch charge £15-50 per applicant and deliver a pass/fail report within 48-72 hours.

Referencing is not the same as tenant screening. Screening is the initial sift of applications (viewing attendance, basic questions). Referencing is the formal due diligence stage after you've selected a preferred applicant.

Mandatory Checks: Right to Rent

Since 1 February 2016, landlords in England must check every adult occupier's immigration status before they move in. This is the Right to Rent check, and it is the only tenant check required by law.

You must see and copy original documents from List A (unlimited right to rent) or List B (time-limited right to rent). Acceptable documents include:

• A British or Irish passport
• A biometric residence permit showing permission to stay in the UK
• A share code from the Home Office online service if the applicant holds settled or pre-settled status under the EU Settlement Scheme

You must check documents in the presence of the applicant, either face-to-face or via a certified Identity Service Provider (IDSP) using video technology. Keep a clear copy of each document and record the date of the check. If you fail to conduct a compliant Right to Rent check, the Home Office can issue a civil penalty of up to £3,000 per illegal occupier.

Right to Rent does not apply in Scotland, Wales or Northern Ireland. It applies only to new tenancies and new occupiers added to existing agreements in England.

Income and Affordability Checks

Most landlords apply an income test: monthly gross salary should be at least 2.5 times the monthly rent. For a property let at £1,200 per month, the applicant needs a gross income of £3,000 per month or £36,000 per year.

You verify income by requesting:

• Three recent payslips (or six months if the applicant is newly employed)
• A letter from the employer on headed paper confirming job title, salary and contract type (permanent, fixed-term, zero-hours)
• Bank statements showing regular salary credits over the past three months

If the applicant is self-employed, ask for the most recent SA302 tax calculation from HMRC and the corresponding tax year overview. Two years of accounts give a clearer picture of stable income. Some landlords accept one year if supported by recent bank statements and a letter from an accountant.

Benefits claimants can provide their Universal Credit statement or a letter from the Department for Work and Pensions (DWP) showing their monthly entitlement. Universal Credit housing element is paid directly to the tenant, not to you, so you must assess whether the total benefit income covers rent and living costs.

If income falls short of your threshold, you can request a guarantor. The guarantor must pass the same referencing checks and typically needs an income of at least 3 times the annual rent.

Credit and Financial History Checks

A credit check reveals County Court Judgments (CCJs), Individual Voluntary Arrangements (IVAs), bankruptcies and payment defaults. It does not tell you if the applicant will be a good tenant, but it flags serious financial distress.

You can run a credit check through Experian, Equifax or TransUnion if the applicant gives written consent. Most referencing companies include a soft credit search in their standard package. A soft search does not affect the applicant's credit score.

Red flags to watch for:

• Active CCJs over £500 in the past 12 months
• Bankruptcy or insolvency within the past six years
• Multiple payday loan defaults or high-cost credit arrears
• Rent arrears listed as a default on the credit file

A single historic default or a satisfied CCJ from several years ago is not automatically disqualifying. Look at the overall pattern. An applicant with stable employment, good references and one old default may still be lower risk than someone with no credit history at all.

If you reject an applicant based on credit information, you must tell them which credit reference agency provided the data. They have the right to request a copy of their file and dispute errors.

Previous Landlord References

Contact the applicant's current or most recent landlord to confirm:

• Tenancy start and end dates
• Monthly rent paid and whether it was paid on time
• Any instances of arrears, late payment or bounced payments
• Condition of the property and whether the tenant met their repair obligations
• Notice period given and whether the tenant left the property clean and undamaged

Ask open questions: "Would you rent to this tenant again?" and "Is there anything I should know before offering them a tenancy?" Some landlords give a glowing reference to a problem tenant just to move them along. Cross-check the landlord's contact details against the tenancy agreement and Land Registry records if you have doubts.

Do not accept a reference from a letting agent who also represents the applicant on the new tenancy — this is a conflict of interest. Always verify the referee is genuinely the landlord or an independent managing agent.

If the applicant is a first-time renter, ask for a character reference from an employer, university tutor or professional contact who can vouch for reliability and responsibility.

Employment Verification

Ring the applicant's employer to confirm the details on the payslips and reference letter. Ask to speak to HR or the line manager. Verify:

• Job title and department
• Employment start date
• Contract type (permanent, fixed-term, probationary, zero-hours)
• Salary and whether any deductions (such as salary sacrifice or attachment of earnings orders) reduce take-home pay

Probationary employees and zero-hours contract workers carry higher risk. If the applicant loses their job in the first three months, rent arrears can escalate quickly. A guarantor mitigates this risk.

For applicants in new employment (less than three months in post), some landlords request six months of rent upfront or a larger deposit if permitted by the Tenant Fees Act 2019. Under the Act, deposits are capped at five weeks' rent for tenancies under £50,000 per year and six weeks' rent for higher-value properties. You cannot ask for more.

Identity and Anti-Money Laundering Checks

You must confirm the applicant is who they claim to be. This overlaps with Right to Rent but goes further for compliance with anti-money laundering (AML) regulations if you manage properties as a business.

Request two forms of ID:

• Photographic ID: passport, driving licence or biometric residence permit
• Proof of current address: council tax bill, utility bill or bank statement dated within the past three months

If the applicant has just moved to the UK or recently changed address, a tenancy agreement from their previous home or a letter from their employer confirming their address is acceptable.

Some landlords use electronic ID verification services such as Credas, Onfido or Yoti. These match the applicant's photo and document against global identity databases and check for signs of forgery or tampering. Fees range from £2 to £10 per check.

Using Referencing Companies vs DIY Checks

Referencing companies automate the process. You submit the applicant's details via an online portal; the company requests documents, runs credit and fraud checks, contacts employers and landlords, and delivers a pass, fail or conditional outcome within 48-72 hours.

Advantages:

• Faster turnaround — most reports in 2-3 working days
• Professional format that tenants and guarantors recognise
• Legal compliance built in (Right to Rent prompts, data protection, audit trail)
• Reduced risk of discrimination claims because criteria are applied consistently

Disadvantages:

• Cost per applicant (£20-50)
• Limited flexibility — automated systems may reject applicants who would pass a manual review
• You still need to interpret conditional outcomes and decide whether to proceed

DIY referencing is free but time-intensive. You must create your own forms, chase referees, verify documents and keep compliant records under GDPR. If you make an error in the Right to Rent check or inadvertently discriminate during referencing, you carry the liability.

For landlords managing one or two properties, a hybrid approach works well: conduct Right to Rent checks yourself and use a low-cost referencing service (£15-25) for credit and employer verification.

Data Protection and Tenant Consent

Tenant referencing processes personal data, so you must comply with the UK General Data Protection Regulation (UK GDPR). Before you collect any information, the applicant must give informed consent.

Your consent form should explain:

• What data you will collect (name, date of birth, address history, employment, bank details, credit file)
• Why you need it (to assess tenancy suitability)
• Who will see it (you, your referencing provider, any guarantor referees)
• How long you will keep it (typically six months for unsuccessful applicants, duration of tenancy plus six years for successful applicants)
• The applicant's rights to access, correct or delete their data

If you use a referencing company, they act as a data processor. You remain the data controller and must have a written contract with the processor that sets out security measures, breach notification and data retention rules.

Do not share referencing reports with other landlords or letting agents unless the applicant gives specific written permission. If you reject an applicant, you do not have to give a detailed reason, but if they request a copy of their data under a Subject Access Request (SAR), you must provide it within one month at no charge.

What Happens If Referencing Fails?

A failed or conditional reference does not mean you must reject the applicant. Common issues include:

• No credit history (common for young tenants or recent immigrants)
• Income just below your threshold
• Employment contract is temporary or probationary
• Previous landlord uncontactable

You can proceed if the applicant provides a UK-based guarantor who passes all referencing checks. The guarantor signs a separate deed of guarantee and becomes liable for rent and damages if the tenant defaults.

Alternatively, you can:

• Request rent in advance (up to six months is common, though not enforceable if the tenant later struggles)
• Accept a higher deposit within the five or six-week cap
• Offer a shorter initial term (six months instead of 12) with a break clause

Never waive the Right to Rent check. If the applicant cannot evidence their legal right to rent in the UK, you cannot grant them a tenancy.

Referencing and Discrimination Law

The Equality Act 2010 protects applicants from discrimination based on age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, and sexual orientation.

You can apply income and affordability criteria as long as you apply them consistently to all applicants. You cannot:

• Refuse to rent to someone receiving housing benefit or Universal Credit (this is indirect discrimination against disabled people and single parents)
• Set different income thresholds for applicants based on nationality or ethnicity
• Reject an applicant because they are pregnant or on maternity leave if their income or guarantor meets your criteria
• Require higher deposits or guarantors from applicants with certain protected characteristics

Keep a written record of your referencing criteria and apply them to every applicant. If you are taken to court for discrimination, evidence of consistent decision-making is your strongest defence.

How Long Does Referencing Take?

Most referencing is completed in 3-5 working days if the applicant submits documents promptly and referees respond quickly. Delays occur when:

• Employers do not answer calls or return reference request forms
• Previous landlords are uncontactable
• The applicant is self-employed and HMRC's SA302 service is slow
• The applicant holds pre-settled status and must generate a share code via the Home Office portal

Set a deadline. Tell the applicant: "Please provide all requested documents within 48 hours. We will complete referencing within five working days of receiving everything." If they cannot meet the deadline, it may signal poor organisation or reluctance to share information.

Referencing for Guarantors

If the tenant needs a guarantor, the guarantor must undergo the same referencing process. Check:

• Income (usually 3 times the annual rent)
• Credit history
• Identity and Right to Rent if they will occupy the property
• Proof of UK residency (guarantors based overseas are difficult to pursue for debt)

The guarantor signs a deed of guarantee before or at the same time as the tenant signs the tenancy agreement. The deed must be witnessed by an independent adult. Once signed, the guarantor is jointly and severally liable for all rent and tenant obligations until the tenancy ends.

Some landlords require a homeowner guarantor. This is not a legal requirement, but it gives you a chargeable asset if you need to enforce the guarantee through court.

What to Do After Referencing Is Complete

Once the applicant passes referencing, confirm your offer in writing. Include:

• Tenancy start date and initial term
• Monthly rent and payment method
• Deposit amount and the name of the deposit protection scheme you will use
• Any permitted fees (holding deposit, which is capped at one week's rent under the Tenant Fees Act 2019)

Send the tenancy agreement for the tenant's review at least a few days before the move-in date. Give them time to read it and ask questions. Do not pressure them to sign on the day of move-in.

Register the deposit with a government-approved scheme (Deposit Protection Service, MyDeposits or Tenancy Deposit Scheme) within 30 days of receiving it. Provide the tenant with the prescribed information about the scheme and how to raise a dispute.

Red Flags During Referencing

Walk away or proceed with extreme caution if you spot:

• Fake or altered documents (mismatched fonts, photoshopped payslips, forged landlord letters)
• The applicant pressures you to skip checks or offers cash upfront to "speed things up"
• Employment or landlord referees cannot be contacted on official phone numbers or email addresses
• The applicant provides multiple different versions of their employment or address history
• Credit file shows active rent arrears or ongoing CCJs for unpaid rent

Trust your instinct. If something feels wrong, do not proceed. The cost of a bad tenant — eviction proceedings, rent arrears, legal fees, and property damage — far exceeds the cost of re-advertising and referencing a new applicant.

Storing and Deleting Referencing Data

Successful applicants' data must be kept for the duration of the tenancy plus six years (the limitation period for contract claims). Store files securely, either in a locked filing cabinet or an encrypted cloud folder with access limited to you and any co-landlords.

Unsuccessful applicants' data should be deleted after six months unless they give consent to keep it on file for future vacancies. If you use a referencing company, check their data retention policy. Most delete unsuccessful reports after 12 months.

If an applicant requests deletion of their data (a "right to erasure" request), you must comply unless you have a legitimate reason to retain it, such as an ongoing legal claim or regulatory investigation.
