Tenant referencing is one of the most important things a letting agent does — and one of the most misunderstood. Done well, it protects your landlord clients from rent arrears, property damage, and nightmare tenancies. Done poorly, it exposes everyone to avoidable risk.
This guide walks through every stage of the referencing process: what checks to run, what the results mean, how to handle borderline cases, and what you must do to comply with Right to Rent legislation.
Rental demand in the UK has surged over recent years, with some agents reporting 20–30 applicants per property. In a frantic market it can be tempting to rush references to secure a good tenant before they take another property. But the average cost of a tenancy gone wrong — arrears, legal fees, and void periods — can run to thousands of pounds.
A thorough reference takes a few extra days. A problematic tenancy can take 12+ months to resolve.
Before anything else, confirm the applicant is who they say they are. Accept:
Check the name matches all other documents exactly. Any discrepancies should be explained in writing before proceeding.
Right to Rent is a legal requirement in England. You must check that every adult tenant has the right to rent residential property in the UK before the tenancy begins — or face a civil penalty of up to £20,000 per occupant.
| Status | Documents Accepted | Follow-up Required? |
|---|---|---|
| British / Irish citizen | Passport or birth certificate + proof of NI number | No — unlimited right to rent |
| EU Settled Status | Share code from UK Visas & Immigration online service | No — permanent |
| EU Pre-Settled Status | Share code | Yes — recheck before pre-settled status expires |
| Visa holder (e.g. student, skilled worker) | Biometric Residence Permit or share code | Yes — recheck before visa expires |
| No current immigration permission | — | Do not let — report to Home Office |
Important: Right to Rent does not apply in Scotland, Wales, or Northern Ireland. However, the Home Office has indicated it may be extended — check the latest guidance.
A credit check reveals County Court Judgements (CCJs), Individual Voluntary Arrangements (IVAs), bankruptcies, and payment history. Use a specialist tenant referencing agency — they access credit data you can't get directly.
What to look for:
The standard rule of thumb is that a tenant's gross annual income should be at least 2.5× the annual rent (some agencies use 30× monthly rent). For a £900/month property, the tenant needs to earn around £27,000 gross.
| Monthly Rent | Minimum Income Required (×2.5) |
|---|---|
| £700 | £21,000 |
| £900 | £27,000 |
| £1,200 | £36,000 |
| £1,500 | £45,000 |
| £2,000 | £60,000 |
For joint tenancies, combined income is used. For self-employed applicants, use 2–3 years of accounts or an SA302 tax return from HMRC.
Contact the applicant's employer directly — not just the HR contact the applicant provides. Verify:
For applicants starting a new job, request a signed contract of employment plus a letter from the new employer confirming start date and salary.
A reference from the tenant's current or most recent landlord is invaluable — and often ignored. Ask specifically:
Watch out: If the "previous landlord" reference comes from a relative's address or a property the applicant claims to own, verify independently. Some applicants fabricate references from renting a room from a friend.
Not every applicant will sail through with a perfect reference. Here's how to approach common borderline situations:
Options include:
A single, old, satisfied CCJ doesn't automatically disqualify a tenant. Assess:
If in doubt, require a guarantor and discuss with your landlord client before proceeding.
Self-employed income can be verified via:
Zero-hours workers present higher uncertainty. Look for consistent income over 12 months rather than just the most recent payslip.
Referencing involves processing significant personal data. You must:
| In-House | Referencing Agency | |
|---|---|---|
| Cost | Staff time only | £15–£40 per applicant |
| Credit data access | Limited | Full bureau data |
| Speed | Varies | 24–72 hours typical |
| Liability | Higher — you own the decision | Some protection if agency negligent |
| Consistency | Depends on staff | Standardised process |
For most agents handling more than a handful of lettings per month, a specialist agency (Homelet, Let Alliance, Rent4Sure, Canopy, OpenRent's referencing tool) saves time and provides better data. For very small agencies, in-house can work with a robust checklist.
Best practice: Whichever route you choose, document your decision on every application — including why you accepted a borderline reference. This protects you if a landlord later disputes the decision.
If you decline an applicant based on referencing, you are not obliged to provide detailed reasons — doing so can expose you to challenges. However:
Benefits discrimination: Many councils and some local laws prohibit "No DSS" policies. While there is no national ban, courts have found blanket refusals of Housing Benefit recipients to be indirect discrimination. Assess each application on its merits — income, not source of income.
If you're managing 50+ tenancies, keeping track of Right to Rent recheck dates, reference statuses, and document expiry dates in a spreadsheet is a recipe for missed deadlines.
Propflow lets you log referencing status per tenant, set Right to Rent recheck reminders, and attach referencing documents directly to tenant profiles — so nothing falls through the cracks.
