Not what you remember. Not what the landlord believes happened. What the documentation can prove, line by line, date by date, to an investigator who has seen every variation of "we always do things properly" and is looking at the evidence in front of them.
For most letting agents, that question is more uncomfortable than it should be. And from 1st May 2026, it matters in ways it simply didn't before.
The Property Ombudsman reported over 73,000 consumer contacts in a single year, with more than 70% of formal cases upheld in favour of consumers. The Tenancy Deposit Scheme handles over 22,000 dispute applications annually, issuing more than 15,000 adjudications. These are not theoretical volumes. They are the environment letting agents are already operating in – and mandatory redress makes every case in that environment more consequential.
What determines the outcome of an investigation is straightforward: evidence. The quality, completeness and timeliness of the documentation an agent can produce when a complaint is raised. Not what the agent remembers. Not what the landlord believes. What the record shows.
For agents still relying on point-in-time inventories as their primary documentation tool, that is a material exposure.
Under the previous framework, a fixed-term tenancy had a natural conclusion – a point at which the evidential record was closed, the deposit settled and the relationship ended. Disputes arose within a defined window.
Periodic tenancies don't work that way. Without a fixed end date, a tenancy can continue indefinitely. The conditions of that tenancy – the property's state, the landlord's compliance with maintenance obligations, the agent's responsiveness to reported issues – accumulate over time as an ongoing record rather than a contained episode. A complaint raised in year three may require an agent to demonstrate what happened in year one.
That is not a future risk. It is the operational reality of managing properties right now.
A more detailed check-in report does not solve the problem of what happens between check-in and check-out. Better photography does not create a maintenance log. A thorough schedule of conditions does not track safety compliance, inspection history or response timelines.
It is worth being clear about what this argument is not saying. The professional inventory clerk – independent, qualified, producing a thorough and impartial record – is not made less important by any of this:
They are made more important.
Under longer, rolling tenancies, the check-in report becomes the baseline for a potentially extended evidential timeline. Without clear, detailed and reliable check-in documentation, TDS guidance is explicit: it becomes significantly more difficult to support deposit deductions through adjudication. The inventory remains critical. It is simply no longer sufficient on its own.
What agents need is a shift in thinking – from a snapshot model to a system model. The property record, rather than the inventory, becomes the operative concept: a living, continuous record that captures not only condition at two fixed points but the full evidential thread of a tenancy. Safety compliance, inspection history, maintenance reporting and response, condition updates, relevant communication. Operational infrastructure, not bureaucracy.
The most effective response is what the construction industry, following the Hackitt Review, calls a golden thread – a single, continuous, unbroken evidential record that runs through the entire life of a property. In lettings, that thread begins before a tenancy starts, with an HHSRS assessment as the property enters the agent's pipeline. It runs through the inventory and check-in, through frequent interim inspections, through Fitness for Human Habitation assessments conducted during the tenancy and fed back into the original hazard record, and through to a check-out that drives maintenance scheduling for the next tenancy rather than simply closing the current one.
Each stage connects to the next. Each document informs what follows. The evidential loop is closed not at the end of a tenancy, but continuously throughout it.
That is the standard the new framework requires. Agents who build it into their operations now – working alongside trained inventory professionals who understand not just what to record but where that record goes next – will be the ones best placed when a complaint is raised and the property record is the only thing that matters.
Because in a redress-led system, you are not judged on what you intended to do. You are judged on what you can prove.
