RRA: Ground 4A Explained: The New Possession Right for Student HMOs

When the government abolished Section 21, it did not leave student HMO landlords entirely without a route to possession. It created a replacement: a new statutory ground sitting within the amended Housing Act 1988, built specifically for the student market and designed to align landlord possession rights with the academic year. That ground is Ground 4A, and it is the single most important piece of legislation you need to understand as a student HMO landlord in 2026.

It is also considerably more complicated than the headlines suggest. Ground 4A is not a simple swap-in for Section 21. It comes with strict qualifying conditions, a prescribed notice structure, a specific window in which possession can be sought, and a set of procedural requirements that, if missed, permanently remove your right to use it for that tenancy. Understanding exactly how it works, where it applies, and where it falls short is not optional for landlords who want to be able to recover their properties at the end of each academic year. It is essential.

This post covers all of it.

The Rule

Ground 4A is a mandatory possession ground under the Renters' Rights Act 2025. Mandatory means that if the ground is properly established and the procedural requirements have been met, the court must grant possession. The judge has no discretion to refuse it. That is a meaningful distinction from discretionary grounds, where a judge can weigh up the circumstances and decline to order possession even if the ground technically applies. Get Ground 4A right, and possession is yours. The academic-year cycle is protected.

But getting it right requires satisfying a checklist of conditions, and every single one of them matters.

The HMO Test. The property must be a house in multiple occupation. This means three or more occupiers from two or more separate households living in the same property. This applies whether or not the property holds a formal HMO licence from the local authority — the licensing threshold and the HMO definition for Ground 4A purposes are independent of each other. Crucially, Ground 4A does not apply to one-bedroom or two-bedroom student properties. A studio flat let to a single student, or a two-bedroom house let to a couple of friends, falls entirely outside the ground's scope regardless of how it is managed or marketed. Those properties are subject to the full periodic tenancy regime with no specialist student possession route available.

The Student Test. All of the tenants must be full-time students, or the landlord must have had reasonable grounds to believe they would become full-time students during the tenancy. The Act specifies that this applies to full-time higher education courses — it is not sufficient that someone is doing part-time study or is enrolled at a further education college on a short course. Landlords should obtain confirmation of full-time student status at the point of letting and retain copies. One important protection is built into this test: if a student drops out or switches to part-time study during the tenancy, the landlord does not automatically lose the right to use Ground 4A, provided they had reasonable grounds to believe the student met the test when the tenancy started. This matters, because student circumstances do change.

The Written Statement. This is the condition that catches the most landlords out, and the consequences of missing it are severe. Before Ground 4A can ever be used, the landlord must have provided the tenants with a written statement at the start of the tenancy confirming three things: that the tenants met the student test when the tenancy was entered into, that the landlord intends to re-let the property to full-time students in future, and that the landlord wishes to be able to recover possession using Ground 4A. This written statement is not optional paperwork. Without it, Ground 4A is permanently unavailable for that tenancy. It cannot be served late and backdated. It cannot be argued around in court. If it was not given at the right time, the ground simply does not exist for that letting.

For existing tenancies that are converting to assured periodic tenancies on 1 May 2026, there is a transitional concession. Landlords who did not include the Ground 4A written statement in their original AST have until 31 May 2026 to serve it as a standalone document. This one-off transitional window also disapplies the six-month advance signing restriction for existing tenancies, meaning landlords whose tenants signed well in advance can still access the ground during this first cycle. After 31 May 2026, that window closes permanently. For all new tenancies created after 1 May 2026, the written statement must be included before the tenancy is signed.

The Notice Period. When a landlord wishes to exercise Ground 4A and seek possession, they must serve a formal Section 8 G4A notice on the tenants giving at least four months' notice. That notice must specify a possession date that falls between 1 June and 30 September. The landlord cannot serve a Ground 4A notice requiring students to leave in October, or in March, or at any other time of year. The window is fixed: June to September, in alignment with the academic calendar. If students do not vacate by the specified date and the landlord needs to pursue a court order, proceedings must be issued promptly — an unexercised notice will eventually lapse.

For the 2026 transitional period specifically, there is a temporary reduction in the notice period. Where a Ground 4A Section 8 notice is served between 1 May and 31 July 2026 against a tenancy that started before 1 May 2026, only two months' notice is required rather than the standard four. This is a meaningful concession for landlords managing the transition in this first cycle and who need possession before or during September 2026. It does not apply to new tenancies entered into after 1 May 2026, where the four-month requirement is always in force.

The New Norm

Ground 4A is now the primary legal mechanism through which student HMO landlords recover possession at the end of each academic year. In that sense it replaces Section 21, which is abolished. But it would be misleading to describe it as a like-for-like replacement, and we want to be honest about that.

Section 21 was blunt, fast, and reliable. A landlord served the notice, gave the required period, and obtained possession. It required no proof of any particular condition. It could not be challenged on its merits, only on procedural grounds. It was the reason student HMO landlords could confidently sign tenancies knowing they could get their property back.

Ground 4A is more conditional and more procedurally demanding. It requires the right type of property, the right type of tenants, documentation served at the right time, a specific notice window, and a minimum notice period that is four times longer than the two-month Section 21 notice most student landlords used. If any condition is not met, the ground fails. If the written statement was not served correctly, the ground fails. If the tenancy was signed too far in advance, the ground fails — though we cover that in detail in the next post in this series, because it is a problem significant enough to warrant its own discussion.

There is also a genuinely open question in the market right now about whether some student HMO landlords will choose not to use Ground 4A at all. The ground's conditions impose a constraint that matters commercially: to use it, tenancies cannot be signed more than six months before the start date. That restriction compresses the letting window significantly, potentially pushing signing to spring rather than autumn for a summer start. Some landlords and agents in markets with strong competition from purpose-built student accommodation — Nottingham being a prime example — have argued that the ability to sign tenants early and secure lettings before Christmas outweighs the benefit of having a formal possession ground against the small number of students who would not otherwise leave voluntarily. If almost all students leave at the end of the year anyway, is the protection Ground 4A offers worth the restriction it imposes on the letting calendar?

That is a legitimate debate, and there is no single right answer. It depends on the property, the market, the landlord's risk tolerance, and their specific tenant profile. What we would say is that the landlords most likely to need Ground 4A are exactly the ones who most need to understand it: those whose tenants are on periodic tenancies, who cannot predict with certainty that students will leave willingly, and who cannot afford to be without a formal legal route to possession if a student decides to stay.

For most student HMO landlords on our books, our view is that Ground 4A is worth using, properly and from day one. The peace of mind it provides is real, and the procedural requirements, while demanding, are entirely manageable with the right documentation in place at the point of letting.

How We're Handling It

At Student Housing, Ground 4A written statements are now a standard component of every new tenancy we create for a qualifying HMO property. We do not treat it as optional paperwork or an add-on to the tenancy agreement. It is part of the core documentation package, served before the tenancy is signed, in the correct form, with the tenants' receipt confirmed.

We have reviewed the requirements under the Act carefully and taken legal guidance on the precise wording and form of the written statement. The content must confirm the student test, the landlord's intention to relet to students, and the landlord's wish to rely on Ground 4A. We have incorporated this into our standard assured periodic tenancy agreement so that it is impossible for the statement to be omitted through oversight.

For all existing tenancies converting on 1 May 2026, we are actively coordinating the service of standalone Ground 4A written statements to qualifying tenants before the 31 May deadline. This is being managed by our branches across Lincoln, Nottingham, and Hull, and we are tracking every managed property to ensure nothing is missed. If you are a Student Housing managed landlord with an HMO that has students in it right now, and you have not yet confirmed with your branch that the Ground 4A written statement process is underway, please contact us immediately. The deadline is firm, and the consequences of missing it are permanent.

On the broader question of whether to use Ground 4A, we are having that conversation with each landlord individually, because the answer is not the same for every property. What we will say here is that landlords who do choose to use it should be under no illusion that it is a passive protection. It requires active, accurate documentation at the start of every tenancy, and it requires the Section 8 notice to be served in the correct form with correct timing when possession is needed. Done properly, it works. Done carelessly, it fails, and when it fails, there is no fallback.

That is exactly why professional management matters more now than it ever did under Section 21. The old system was forgiving of imprecision. The new one is not.
