Tenant Referencing and Right-to-Rent Checks

Tenant referencing is the single most consequential decision in the life of a tenancy. A well-referenced tenant produces an uneventful, profitable let; a poorly-referenced tenant produces arrears, disputes, and possession proceedings. This page sets out what professional referencing covers, the right-to-rent check requirements under the Immigration Act 2014, the anti-discrimination rules under the Renters’ Rights Act 2025, and the practical process landlords should follow to make defensible selection decisions.

Why referencing matters more than landlords often think

Tenant referencing is the single most consequential decision in the life of a tenancy. A well-referenced tenant who can afford the rent, has a clean rental history, and intends to live in the property responsibly is the foundation of a profitable and uneventful let. A poorly-referenced tenant is the foundation of arrears, possession proceedings, and damage to the property — all at the landlord’s cost.

Yet referencing is the area where many landlords cut corners. The temptation to accept the first plausible applicant — particularly when a property has been empty for a few weeks — is real. The cost of that temptation is rarely visible at the moment the tenancy starts. It becomes visible six months later when the rent stops coming in, the tenant cannot be served at the address they gave, and the deposit covers a fraction of the eventual loss.

Professional referencing takes time and costs money. Both are recoverable many times over against the cost of letting to the wrong tenant.

What good referencing covers

A complete reference for a prospective tenant covers six areas:

1. Identity verification

Confirm the applicant is who they say they are. Photographic ID — passport or driving licence — checked against the person physically in front of you (or video-verified). Compare the name and date of birth to other documents provided. A surprising number of fraudulent rental applications are detected at this stage simply because the documents do not align.

2. Right-to-rent check

Mandatory under the Immigration Act 2014. Distinct from general identity verification because it has specific statutory requirements about which documents are acceptable and how they must be examined. Detailed below.

3. Employment and income

Verify the applicant has the income they claim. The standard verification is a payslip dated within the last three months and a letter from the employer on company headed paper confirming the role, salary, and length of employment. For self-employed applicants, the standard is two years of accounts certified by an accountant or two years of SA302 self-assessment statements from HMRC.

The standard affordability test is that gross annual income should be at least 30 times the monthly rent (i.e. 2.5 times the annual rent). A property at £1,500 per month rent requires applicants with at least £45,000 gross annual income. The 30× threshold is industry standard but not legally prescribed; landlords can apply different thresholds provided they do so consistently and without discriminating on prohibited grounds.

4. Previous rental history

Contact the previous landlord directly. Ask whether the rent was paid on time, whether the property was kept in reasonable condition, whether there were any issues during the tenancy, and whether the previous landlord would let to this tenant again. Get the answer in writing where possible — email is fine.

A previous-landlord reference is more valuable than almost any other information. A landlord who has dealt with this tenant before knows what they are like. The reference also flags any gaps in the rental history — a tenant who lists a previous address but cannot provide a contactable previous landlord may be hiding a difficult tenancy or have lived somewhere they would rather not disclose (a parent’s home, a property they did not have authority to occupy, or a rental that ended badly).

5. Credit history

A credit check via a referencing agency reveals any County Court Judgments (CCJs), bankruptcies, defaults, or substantial unsecured debt. A clean credit file is reassuring; a file with multiple recent defaults is a warning sign. Recent applications for credit suggest financial pressure that may worsen during a tenancy.

The cost of a basic credit check is typically £10-£30 per applicant, paid by the landlord. The applicant must consent — and consent must be informed (the applicant must know what is being checked). Refusal of a credit check is a legitimate ground for refusing the application; the alternative is a guarantor.

6. Bank statements (where appropriate)

For applicants with limited rental history or a thin credit file, three months of bank statements give a fuller picture: regular income, regular outgoings, presence or absence of payday lending, evidence of savings. Asking for bank statements is more intrusive than the other reference checks and should be reserved for cases where the other references leave doubt — not used as a default.

The right-to-rent check

The right-to-rent regime is set out in the Immigration Act 2014. It applies to every adult occupier of every privately let residential property in England (the regime does not apply in Wales, Scotland, or Northern Ireland). Failure to comply is a civil offence.

What you must do

Before the tenancy starts, the landlord (or letting agent) must:

• Ask each adult occupier to provide original documents from the prescribed list (or a digital share code for those with eVisas).
• Examine the documents in the physical presence of the applicant — or via video call where the applicant is participating in person from elsewhere.
• Check the documents are genuine, the photograph matches the applicant, and any expiry dates allow the tenancy to begin within the right-to-rent period.
• Make and retain copies of the documents — the photo page of a passport, the front and back of a residence permit — for the duration of the tenancy and at least one year afterward.
• Record the date of the check.

Acceptable documents

There are two lists of acceptable documents — List A (giving an unlimited right to rent) and List B (giving a time-limited right to rent that requires re-checking). The most common documents:

List A — UK passport, UK birth certificate combined with a National Insurance document, EU/EEA passport with a settled or pre-settled status share code, a UK Biometric Residence Permit indicating ILR.

List B — passports of various nationalities with a current visa, a Biometric Residence Permit indicating limited leave, an immigration status document with a positive endorsement.

For List B documents, the right-to-rent period is the time-limited period of the document. The landlord must re-check before the period expires. If the right has lapsed and the occupier has no continuing right to rent, the landlord must report this to the Home Office.

Online checks (eVisas)

From 2025, an increasing share of right-to-rent checks are conducted online via the Home Office’s right-to-rent online service. The applicant generates a share code and provides it (with their date of birth) to the landlord; the landlord enters it on the gov.uk service and confirms the check. Online checks satisfy the statutory obligation in full and are quicker than physical document checks.

Penalties for failure

A landlord who lets to an occupier without a right to rent is liable for a civil penalty of up to £5,000 per occupier for a first offence , rising to £10,000 per occupier for a repeat offence. The penalty regime tightened in 2024 after several years of relatively low penalties; the new figures are aligned with the broader housing enforcement framework.

A landlord who carries out the prescribed check correctly has a “statutory excuse” — they cannot be penalised even if it later transpires the documents were forged or the occupier had no actual right to rent. The check, properly carried out, is the protection.

Anti-discrimination — what you cannot do

The Renters’ Rights Act 2025 introduced explicit prohibitions on discriminating against prospective tenants on certain grounds. These sit alongside the longer-standing prohibitions in the Equality Act 2010. A landlord or letting agent cannot lawfully:

• Refuse to enter into a tenancy with someone because they have children or because they live with children.
• Refuse to enter into a tenancy with someone because they are in receipt of benefits — including Universal Credit, Housing Benefit, Personal Independence Payment, and others.
• Discriminate on any of the protected characteristics in the Equality Act 2010: age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, and sexual orientation.

Direct discrimination — refusing a tenant because of one of the prohibited grounds — is unlawful regardless of intent. So is indirect discrimination — applying a criterion that disproportionately disadvantages a protected group without legitimate justification. Examples of indirect discrimination that have been found unlawful:

• Requiring an income multiple that effectively excludes most benefit recipients.
• Requiring UK-only employment history (which disadvantages recent migrants).
• Requiring a guarantor with UK home ownership (which disadvantages applicants without UK-based family).

Selection criteria must be objective and applied consistently to every applicant. They should be documented (so they can be evidenced if challenged) and they should be capable of justification on legitimate, non-discriminatory grounds.

How to handle a competitive let

Where a property attracts multiple applicants, the temptation is to choose between them on intuitive grounds. This is where discrimination claims commonly arise — not from explicit prejudice, but from the landlord choosing the “easier” candidate without articulating why.

A defensible process:

1. Document your selection criteria in writing before viewings. Income threshold (e.g. 30× monthly rent), employment status (employed, self-employed with two years’ accounts, retired with pension), no recent CCJs, contactable previous landlord. Apply consistently.

2. Reference all suitable applicants in parallel where possible. Decide based on the references, not on the order of application or the applicant’s appearance.

3. Communicate decisions briefly and professionally. An unsuccessful applicant who asks why does not need a detailed analysis — but they should not be told something untrue or evasive that suggests prohibited grounds.

4. Keep records. Selection criteria, references obtained, decisions taken, dates. Discrimination claims that succeed are usually those where the landlord cannot evidence the basis of the decision.

Critically: rental bidding wars have been prohibited since 1 May 2026. A landlord cannot accept offers above the advertised rent or invite applicants to bid against each other. The advertised rent is a ceiling, and selection must be on grounds other than willingness to pay more.

Using a referencing agency vs DIY

Many landlords use professional referencing agencies — services like FCC Paragon, HomeLet, RentPro, Goodlord, and others. The agencies typically charge £20-£60 per applicant and provide a structured report covering identity, right-to-rent, credit, employment, income, and previous landlord references in 2-5 working days.

The advantages: speed, structure, professional database access, and an audit trail if a decision is challenged. The disadvantages: cost (though often passed to the tenant indirectly through other charges), occasional incomplete data, and reduced personal contact with previous landlords.

Doing it yourself is workable for a small portfolio but slower and less consistent. The right answer for most landlords:

• For 1-3 properties: DIY referencing is reasonable. Get an identity check, employment and income verification, previous landlord reference (you do this yourself), and a credit check via a third-party service.
• For 4+ properties or commercial-quality service: use a referencing agency for the structured database checks, then add your own previous-landlord call.

Either way, document everything. The reference file for each tenant becomes part of the permanent record of the tenancy.

Red flags

A few specific warning signs from years of landlord experience:

Reluctance to provide previous landlord details. Most acceptable explanations (the property was a relative’s; the landlord is overseas; the tenancy was very short) can be verified. Persistent inability to provide a contactable reference is a warning.

Income that does not align with employment. A claimed income substantially higher than typical for the stated role is worth questioning.

Recent address changes without clear reason. Frequent moves (more than every 12-18 months) without obvious explanation suggest difficulties at previous tenancies.

Reluctance to provide bank statements where the credit file is thin. An applicant with no substantial credit history but unwilling to evidence income through bank statements may be obscuring the picture.

Pressure to move in quickly. Genuine urgency exists (work relocation, relationship breakdown, lease ending). Pressure that forecloses proper referencing rarely is.

Cash payment offers. A few months’ rent in cash up front is sometimes a legitimate convenience but more often a way to avoid a referencing process the applicant cannot pass. Note also that the Renters’ Rights Act 2025 caps rent in advance at one month after signing — taking more is now unlawful.

None of these red flags is conclusive. Each one warrants further investigation. Multiple flags appearing together warrant declining the application.

What good referencing actually looks like

A landlord who references thoroughly typically has a file for each tenant containing: a copy of the photo ID, a record of the right-to-rent check (with copies of the documents examined and the date), a payslip and employer letter, two months of bank statements (if requested), a previous landlord reference (in writing), a credit report, and the applicant’s consent to all the checks. The file takes 30-60 minutes to assemble per applicant and costs £30-£80 in third-party fees.

That investment is the difference between a tenancy that runs uneventfully for three or four years and one that ends with arrears, court fees, and damage exceeding the deposit. The economics are not subtle.
