Most agency growth plans are all attack: more marketing, more valuations, more landlords through the door. Almost none of them are about defence — keeping the landlords already on the books and protecting them from the one thing that makes them leave. It is a leaky bucket, and you cannot fill a leaky bucket by pouring faster.
The defence, unglamorous as it sounds, is tenant referencing and vetting. Get it right and landlords stay, arrears cases fall, and your reputation does the marketing for you. Get it wrong and you lose the landlord, the fee, and the next three they would have referred. Here is the growth case for taking it seriously in 2026.
General guidance for letting agents.
The leaky bucket
A landlord who leaves is not one lost fee — it is every future fee from that property, plus the ones they would have sent your way. And landlords rarely leave over price. They leave over a bad tenant: arrears, damage, a possession case that dragged, the sense that the agent did not protect them.
Every one of those traces back to who was let in. So the cheapest growth an agency can buy is not another lead campaign; it is making sure the tenants it places are the right ones. Retention is growth that compounds, and referencing is where retention starts.
Fraud made the stakes much higher
This is not the referencing environment of five years ago. According to Cifas Fraudscape 2026, filings for tenant referencing fraud rose 263% in a year, driven by false and altered documents and, increasingly, AI-generated ones. And the automated checks a lot of agencies lean on are not keeping up: in testing, they flagged only about 26% of AI-generated IDs — so "the system checked it" is worth far less than it sounds.
For an agency that means a payslip that looks perfect and a reference that ticks a box are no longer enough. The landlord who ends up with a fraudulent tenant does not blame the fraudster; they blame the agent who vetted them.
It is also what landlords now choose you for
Referencing is not just a defence against churn — it has become a reason landlords pick one agent over another. When a landlord is deciding who to trust with their property, "how do you vet tenants?" is increasingly the question, because they have read the same fraud headlines you have. An agency that can answer it clearly — a regulated credit reference agency, affordability, identity, adverse data, a real process — has a selling point the agency down the road waving a lower fee does not.
So the same thing that keeps your existing landlords also wins new ones. That is why it is a growth engine, not a cost centre.
What good vetting actually looks like
Defence and growth in one place
The reason agencies treat referencing as an afterthought is usually that it lives outside their main system — a separate portal, a separate login, disconnected from the tenancy and the landlord relationship. That is exactly what makes it easy to skimp on.
LetCompliance puts the defence where the growth is: referencing through a regulated UK credit reference agency and a deeper Tenant Risk Report, stored on the tenancy, alongside the compliance score, rent and statements landlords judge you on — with multi-branch agency workspaces and client accounting in the same login. One place to run the operation you are actually judged on, so keeping landlords stops being a hope and becomes the system.

Frequently asked questions
How does tenant referencing help a letting agency grow?
By keeping the landlords you already have. Landlords rarely leave over price — they leave over a bad tenant (arrears, damage, a dragged-out possession), which traces back to who was let in. Good referencing keeps landlords, cuts arrears cases and builds the reputation that wins referrals, so retention compounds into growth. It is also increasingly what landlords choose an agent for in the first place.
How bad is rental fraud for agents in 2026?
Significant and rising. Cifas Fraudscape 2026 recorded a 263% rise in tenant referencing fraud filings in a year, driven by false, altered and AI-generated documents, and in testing automated checks flagged only about 26% of AI-generated IDs. A payslip that looks perfect and a box-ticked reference are no longer enough — and the landlord who ends up with a fraudulent tenant blames the agent who vetted them.
What does good tenant vetting look like for an agency?
A regulated UK credit reference agency rather than a tick-box form — credit history, affordability against the rent and adverse data — plus identity and Right to Rent handled with the fraud reality in mind, guarantors referenced to the same standard, the result stored against the tenancy as evidence, and a visible process you can explain to a prospective landlord. That process is both a defence against churn and a selling point that wins new instructions.
