What Happens When a Tenant Fails Referencing?

References don't come back as a simple pass or fail — they return data, and it's the agency's job to interpret it. An income shortfall with a clean credit history is a very different situation from a history of CCJs and a negative landlord reference. The response should reflect that distinction.

When a reference flags concerns, there are broadly four paths forward.

Decline the application. Sometimes the right call — particularly where serious credit issues, fraud indicators, or a failed Right to Rent check are involved. Right to Rent failures leave no room for discretion: proceeding exposes the landlord to fines of up to £20,000 per tenant under the Immigration Act 2014.

Accept with a guarantor. The most common route when income is the primary concern. The guarantor needs to be properly referenced — not just named. Income, credit, identity, and since May 2025, AML and sanctions screening all apply. A guarantor accepted without adequate checks provides security on paper only.

Accept with documented risk. Where only one element of the reference is borderline, a landlord may choose to proceed. That decision should be in writing. If a landlord overrides an agent recommendation, the letting agency needs a paper trail — a verbal "they said it was fine" is not sufficient protection if things go wrong later.

⚠️ Holding deposits: Under the Tenant Fees Act 2019, if the tenancy doesn't proceed, a holding deposit must be returned within 7 calendar days unless a specific retention ground applies — such as the tenant providing false information or failing a Right to Rent check. Missing that deadline is a breach, regardless of why the tenancy fell through.

How an agency communicates a failed reference matters as much as the decision itself. Tenants should be told promptly, in general terms, what the concern is and whether any options exist. Landlords should receive a clear briefing on what the data shows — not vague reassurance — so they can make an informed decision about how to proceed.

Leaving either party to chase for an update, or giving a verbal steer before the position is confirmed, creates complaints that have nothing to do with the tenant's referencing outcome and everything to do with how the process was handled.

Under UK GDPR: Tenants have the right to know that a decision has been made based on their data and understand the general grounds for it. Agencies don't need to hand over the full report, but they do need to communicate clearly. The ICO guidance is straightforward on this.

A failed reference is a piece of information, not a crisis. The agent's job is to interpret it honestly, communicate it clearly, and ensure that whatever decision is made — by the landlord or the letting agency — is documented. The agencies that do this consistently are the ones landlords trust with their most difficult tenancies.
