How to Screen Tenants Effectively in London

Choosing the right tenant is one of the most important decisions a London landlord makes, and one of the easiest to get wrong by relying on instinct. A confident applicant who turns up early to a viewing is not necessarily a reliable payer, and a quieter applicant with steady finances may turn out to be the tenancy that runs smoothly for years. Effective screening replaces gut feeling with a consistent, fair process that you apply to everyone in the same way. This is partly good practice and partly a legal requirement, because the rules now place clear limits on how landlords can assess and select tenants.

Start with a clear, lawful position

Before you advertise, decide what the property genuinely requires and write it down. Screening works best when your criteria are set out beforehand and applied identically to every applicant, rather than adjusted case by case. That protects you against accusations of unfair treatment and gives you a clean record of why a decision was made.

It is worth being clear about what you cannot do. You must advertise an asking rent and you cannot invite or accept offers above it, so screening is never about finding who will pay the most. Discrimination against families with children or against tenants in receipt of benefits is prohibited, and the Equality Act 2010 protects a range of characteristics. The aim of screening is to confirm that an applicant can afford and look after the property, nothing more.

Understand what referencing actually checks

Most landlords and agents assess affordability and reliability through a formal reference. If you are new to the process, our guide to how tenant referencing works walks through it step by step, but the essentials are straightforward. A reference typically confirms identity, looks at income against the rent, checks credit history for adverse records such as County Court Judgments, and seeks a view from a previous landlord and, where relevant, an employer.

None of this is a verdict on someone as a person. It is a structured way of answering one question: on the evidence, is this tenancy likely to be affordable and well kept? Treating it that way keeps the process objective and consistent.

Assess affordability sensibly

Affordability is the single most useful signal you have. The conventional approach is to compare a household's income against the annual rent, and a reference provider will usually apply a clear ratio so that the rent sits comfortably within what the household earns. Combined incomes from joint applicants can be assessed together.

Where an applicant is self-employed, recently arrived in the UK, or moving from abroad, standard income evidence may be harder to produce. That does not mean the tenancy is risky; it means you may need different evidence, such as accounts, savings or an employer's confirmation of a role. A guarantor can also be referenced to stand behind the rent. The point is to look for genuine financial substance rather than to default to a yes or a no.

Get the documents right

Screening only works if the paperwork behind it is sound. Ask every applicant for the same set of documents so that nobody is treated differently, and so that your reference provider has what it needs to reach a fair view. Our breakdown of the documents a tenant needs to pass referencing sets this out in full, but a reasonable starting list includes:

• Proof of identity and the right to rent in the UK
• Recent payslips or, for the self-employed, accounts or tax documents
• Bank statements covering a recent period
• Contact details for a current or previous landlord and, where appropriate, an employer

Gathering this consistently at the application stage avoids delays later and means a decision rests on evidence rather than impression.

Carry out Right to Rent checks correctly

Right to Rent immigration checks are a legal requirement before a tenancy begins, and they sit alongside affordability rather than replacing it. The current and simplest method for most applicants is the online share code: the applicant obtains a share code through the government service and gives it to you along with their date of birth, and you confirm their status online. British and Irish citizens are generally evidenced through document checks instead.

It is important to apply this check to every applicant in the same way. Singling out particular tenants for extra scrutiny based on how they look or sound is both unfair and unlawful. A uniform check, recorded properly, is the safe approach.

Be careful about fees and holding deposits

Screening costs money, but you cannot pass referencing or admin charges on to tenants. The Tenant Fees Act 2019 prohibits charging tenants for referencing and most administration, and a holding deposit is capped at one week's rent. If you take a holding deposit to reserve a property while checks are completed, handle it correctly and be clear about the limited circumstances in which it can be retained.

This is one of several areas where using an agent removes risk. If you want to understand the wider remit, our overview of what a letting agent does in London covers how compliant screening fits alongside marketing, referencing and ongoing management. A letting agent holding client money must also have Client Money Protection and be a member of a redress scheme.

Screen for the tenancy you will actually have

The legal backdrop to every London tenancy has changed, and screening should reflect that. Under the Renters' Rights Act 2025, tenancies are periodic and roll month to month, fixed terms have gone, and possession can only be sought on specific Section 8 grounds. In practice this means the quality of your initial assessment matters more than ever, because you are entering an open-ended arrangement rather than a fixed contract with a built-in end date.

It also means you should not treat any single group of tenants as inherently superior. Corporate relocations, including the Japanese corporate tenants we frequently work with, are one segment among many and bring their own paperwork and timelines. They are assessed on the same affordability and reference basis as everyone else, not given preferential treatment.

Keep a fair, written record

Whatever decision you reach, write down the basis for it. If an application does not proceed, the reason should be objective and tied to your stated criteria, such as affordability not being demonstrated on the evidence provided. A clear, consistent record protects you if a decision is ever questioned and helps you improve your process over time.

Done well, screening is not about excluding people. It is about giving every applicant a fair and identical assessment, then matching the right household to the right home so the tenancy works for both sides.
