In today’s rental market, landlords face a difficult balancing act. On one hand, carrying out robust affordability checks is essential to reduce arrears and protect your investment. On the other hand, applying screening criteria incorrectly or inconsistently can lead to accusations of discrimination under UK law.
With increased scrutiny around tenant selection and greater awareness of renters’ rights, it has never been more important for landlords to understand the difference between legitimate affordability checks and unlawful discrimination.
Here’s how you can stay compliant, protect your property, and reduce risk, without falling into legal pitfalls.

Why affordability checks matter
Affordability checks are a fundamental part of responsible letting. They help landlords assess whether a prospective tenant is financially able to sustain rent payments throughout the tenancy.
A typical affordability assessment may include:
- Income verification (payslips, contracts, tax returns)
- Employment references
- Credit checks
- Previous landlord references
- Benefit income confirmation (if applicable)
A common approach used by letting agents and referencing providers is to apply a set affordability benchmark. This usually means a tenant must earn at least 30 times the monthly rent annually, or have a monthly income equivalent to 2.5–3 times the rent.
Used correctly, this type of financial assessment is entirely legitimate. Affordability checks are an important part of managing risk and helping to prevent rent arrears.
Difficulties arise when these criteria are enforced rigidly or without proper justification, particularly if their application is indirect and disadvantages certain groups.
Understanding discrimination in the private rental sector
Under the Equality Act 2010, landlords must not discriminate against tenants based on protected characteristics. These include race, disability, sex, religion or belief, pregnancy and maternity, sexual orientation, gender reassignment, age, and marriage or civil partnership.
Discrimination can be:
- Direct discrimination – treating someone unfairly because of a protected characteristic.
- Indirect discrimination – applying a rule to everyone that unfairly affects certain people, without a valid reason.
- Disability discrimination – failing to make reasonable changes or adjustments for a disabled tenant.
Recent legal cases have highlighted how blanket policies such as refusing tenants in receipt of benefits can amount to indirect discrimination, particularly affecting women and disabled applicants.
This is where affordability checks and discrimination concerns can intersect.
“No DSS” and blanket policies: Why they’re risky
Historically, some landlords advertised properties as “No DSS” or “No benefits”. However, court rulings have clarified that blanket bans on tenants receiving Universal Credit or housing support may constitute indirect discrimination.
Why? Because women and disabled individuals are statistically more likely to receive certain benefits. A policy that excludes all benefit recipients can therefore disproportionately impact those groups.
Even if your concern is rent security, a blanket refusal is unlikely to be legally defensible.
Instead, landlords should assess affordability based on the individual’s overall financial position, not the source of income.
How to conduct lawful affordability checks
The key to staying compliant is consistency, transparency, and evidence-based decision-making.
- Set the Standard – Define clear affordability rules and apply them consistently to every applicant.
- Follow the Money – Assess total verified income, not just employment status.
- Protect with a Guarantor – Use a suitable guarantor to strengthen applications that fall slightly short.
- Stay Fair and Flexible – Make reasonable adjustments where required, particularly for disabled tenants.
- Decide with Evidence – Base every decision on documented affordability checks, never assumptions.
Protecting yourself financially without discriminating
Some landlords worry that removing strict criteria increases exposure to arrears. In reality, you can reduce risk in several compliant ways:
Rent Guarantee Insurance
This can cover missed payments and legal costs in the event of arrears. Many policies require full referencing, reinforcing the importance of structured affordability checks.
Professional Referencing Services
Using a regulated referencing provider ensures assessments are consistent and documented. This provides an audit trail if your decision is ever challenged.
Clear Tenancy Agreements
Under the new periodic tenancy system (under The Renters’ Rights Act), a clear written agreement remains essential. It should clearly outline rent terms and responsibilities to protect both landlord and tenant.
Regular Reviews
Monitor rent payments closely and act promptly if issues arise. Early intervention is often more effective than reactive enforcement.

Documentation: Your best legal protection
If an applicant challenges your decision, your defence will depend on clear documentation. Keep records of your written affordability policy, income calculations, referencing reports and specific financial reasons for declining. Avoid vague explanations such as “not suitable” and instead record clear, evidence-based reasons. Clarity and documentation are essential.
Protect your investment the right way
Staying compliant while protecting your rental income can be complex, particularly as legislation evolves. A professional letting agent can help by carrying out compliant referencing, applying consistent affordability criteria and advising on discrimination risks, while offering options such as rent protection.
Affordability checks themselves are entirely legitimate, but blanket bans, inconsistent standards or decisions based on assumptions can create legal exposure. The key is to use clear written criteria, assess total income fairly, document your decisions and rely on objective financial evidence. With the right processes and the right support, landlords can reduce risk while remaining fully compliant with the law.
