Deposit Registration Under the Renters' Rights Act: The Liability Trap Letting Agents Are Already Falling Into

The Renters' Rights Act became law on 1 May 2026, and within weeks the industry is already identifying a compliance fault line that has received considerably less attention than Section 21 abolition or pet consent obligations. The fault line is deposit registration, and the warnings now circulating among letting agents are not theoretical. They reflect a structural change in how tenancies are created under the new regime, one that has quietly invalidated assumptions that landlords and their agents have operated on for over a decade.

Under the Housing Act 2004, the thirty-day clock for protecting a tenancy deposit was well understood. Landlords and agents knew when a tenancy started, registered the deposit, and issued the prescribed information accordingly. The process was linear because fixed-term tenancies had a defined commencement date. The Renters' Rights Act has altered that architecture entirely. All new tenancies are now periodic from day one. There is no fixed term. That single change, which has been discussed almost exclusively in the context of possession reform, carries a direct consequence for deposit compliance that the sector is only beginning to absorb.

The question of precisely when the deposit protection clock begins on a statutory periodic tenancy has generated inconsistent practice. Some agents are treating the rental commencement date as the trigger, which is correct. Others, operating on inherited workflows designed for fixed-term agreements, are introducing delays because their compliance checklists were built around a tenancy lifecycle that no longer exists. Agents warned by Propertymark and other professional bodies about this risk are being told, in plain terms, that getting this wrong exposes the landlord, not the agent, to the financial penalty. That distinction matters enormously and it deserves unpacking.

Who Bears the Legal Liability When an Agent Registers Late?

The statutory obligation to protect a deposit sits with the landlord. Section 213 of the Housing Act 2004 is explicit: the person who has received the deposit, or on whose behalf it has been received, is responsible for compliance. Where a letting agent collects and holds the deposit as agent for the landlord, the landlord remains the liable party in the eyes of the tribunal. If an agent fails to register within thirty days, or fails to serve the prescribed information correctly, the penalty falls on the landlord. That penalty is a minimum of one times the deposit and a maximum of three times the deposit, awarded to the tenant by a tribunal, in addition to the deposit itself being returned.

This has always been the legal position, but it was a manageable risk in a world where fixed-term tenancies gave agents a clear and predictable workflow. The Renters' Rights Act has introduced a new category of error: agents who do not yet understand that periodic tenancies require immediate registration rather than registration pegged to a fixed-term start date in a system built for that purpose. Where agents are managing large portfolios through automated compliance platforms, those platforms have in many cases not been updated to reflect the new tenancy structure. Over three hundred agencies are reportedly in the process of onboarding new AI compliance platforms, but onboarding is not the same as operational compliance. A landlord whose agent is mid-migration between systems is a landlord who may be unprotected.

The practical exposure is compounded by the prohibition on serving a valid Section 21 notice where deposit compliance was deficient, a prohibition that is now moot given Section 21 abolition, but which has been replaced by a different risk. Under the Renters' Rights Act, a landlord who cannot demonstrate proper deposit registration may face an extended barrier to possession through the tribunal system, where delays are already severe. Any procedural deficiency that hands a tenant a legitimate counterclaim transforms what should be a straightforward possession case into protracted litigation. Landlords who have relied entirely on their agent's compliance record without independent verification are carrying a risk they have not priced.

What Does Correct Compliance Actually Require on a Periodic Tenancy?

The mechanics of deposit protection on a periodic tenancy created under the Renters' Rights Act require landlords and agents to work through several practical questions that did not previously arise with the same urgency. First, the deposit must be registered with an approved scheme within thirty days of receipt. Receipt is the operative word, not the date the tenancy agreement is signed, and not the date the tenant takes possession if those dates differ. Agents who collect holding deposits that convert into tenancy deposits upon signing need a compliance process that identifies that conversion point precisely.

Second, the prescribed information must be served on the tenant and any relevant person within the same thirty-day window. Prescribed information includes the scheme leaflet, the contact details for the scheme, details of the circumstances under which deductions may be made, and the procedure for resolving disputes. On a periodic tenancy, there is no renewal event that might otherwise prompt an agent to re-serve this information. The periodic tenancy simply continues indefinitely, which means the initial service of prescribed information is the only opportunity to get it right. Agents who historically re-served prescribed information at the start of each fixed-term renewal have lost that natural compliance checkpoint.

Third, where deposits were taken before 1 May 2026 under a fixed-term tenancy that has since transitioned to a periodic tenancy under the new Act, landlords should take legal advice on whether re-service of prescribed information is required. The Act created a transition mechanism for existing tenancies, but the precise obligations on prescribed information in that transitional period are not uniformly understood across the sector. The cautious position, and the one with the stronger legal footing, is to re-serve prescribed information where there is any doubt about the current documentation's validity.

Landlords managing portfolios through agents should now be requesting written confirmation from those agents of the deposit registration status of every tenancy, the scheme used, the registration date, and the date on which prescribed information was served. That request should be documented. If an agent cannot produce that information within a reasonable timeframe, the landlord has identified a risk that needs to be remediated before a tenant raises it in tribunal proceedings.

Does the Industry's Warning System Reach Landlords in Time?

Professional bodies including Propertymark and the NRLA have issued guidance on deposit risks under the Renters' Rights Act, but the reach of that guidance is uneven. It reliably reaches agents who are members of professional bodies and landlords who are actively engaged with sector organisations. It does not reliably reach the significant portion of private landlords who operate without professional memberships, manage properties themselves without agent oversight, or who have not revisited their compliance arrangements since the Act came into force three weeks ago.

The enforcement environment makes timing critical. As this publication has previously reported, councils have moved away from proactive warning and toward direct enforcement action. A council housing officer who identifies a deposit compliance failure during a routine inspection or in response to a tenant complaint is unlikely to issue an informal advisory. The pattern across local authorities has shifted toward immediate penalty notices and tribunal referrals. In that context, the thirty-day window for deposit registration is not a guideline with soft edges: it is the boundary beyond which liability begins to accrue.

Landlords who use regulated agents have contractual recourse if an agent's negligence causes a deposit compliance failure. Pursuing that recourse through the courts or an approved redress scheme takes time and money that a tribunal penalty does not defer. The more effective strategy is verification before any dispute arises. The Renters' Rights Act has created enough structural novelty in tenancy creation that every landlord using an agent should treat deposit compliance as an item requiring their own independent confirmation, not a delegated obligation they can assume is being handled correctly.
