Ground 4A for Student HMOs: Why the New Possession Route Is Riskier Than You Think

The End of Fixed-Term Tenancies Just Changed Everything for Student Landlords

As of 1 May 2026, the Renters' Rights Act has officially abolished fixed-term tenancies across England. For most landlords, this shift has been discussed for months. But for student HMO landlords in London, the reality is only just sinking in.

The traditional model was beautifully simple: sign students on a fixed-term tenancy each September, let it expire naturally the following June or July, turn the property around over summer, and re-let to a fresh cohort. Rinse and repeat. That model is now gone.

In its place, Parliament introduced Ground 4A, a brand new possession ground designed specifically for student HMOs. On paper, it sounds like a reasonable replacement. In practice, it is far narrower than many landlords realise, and it introduces real legal risk into what used to be one of the most predictable letting cycles in the market.

How Ground 4A Actually Works

Ground 4A is a mandatory possession ground, meaning a court must grant possession if the conditions are met. That part sounds reassuring. But the conditions themselves are where things get tricky.

To use Ground 4A, all of the following must be true:

• The property must be a purpose-built or designated student HMO.
• Every single tenant in the property must be a full-time student at the point the tenancy was granted.
• The landlord must have given written notice at the start of the tenancy confirming that Ground 4A may be used.
• The landlord must serve a valid Section 13 notice giving at least two months' notice, timed correctly to align with the academic cycle.

Miss any one of these steps and the ground falls apart. For example, if one tenant in a five-bed HMO defers their studies, drops out mid-year, or switches to part-time status after moving in, you may find yourself unable to rely on Ground 4A at all. The requirement that every tenant is a full-time student is strict and applies at the point of grant, but any ambiguity around status could still create grounds for dispute.

The Notice Requirements Are Unforgiving

Under the old fixed-term model, the tenancy simply expired. There was no notice to serve and no process to follow. Ground 4A flips this entirely. You now need to serve notice proactively, with perfect timing, and any procedural error could delay possession by months.

Given that the summer turnaround window for student lets is typically just four to six weeks, even a short delay can mean missing the September intake entirely. That is not a minor inconvenience. That is a full year of lost income or a forced pivot to a different tenant demographic at the worst possible moment.

Why This Creates Real Risk for London Student HMO Landlords

London's student rental market has always been competitive and lucrative. But the appeal was built on predictability: guaranteed annual turnover, strong demand each autumn, and minimal void periods. Ground 4A undermines every one of those pillars.

Here are the key risks landlords need to be watching:

Untested legal territory. Ground 4A has never been tested in court. There is no case law, no judicial guidance, and no established precedent for how tribunals will interpret edge cases. Early adopters will essentially be guinea pigs.

Tenant challenges. Under the new Act, tenants have stronger protections and more avenues to challenge possession notices. Even a well-prepared landlord could face delays if a tenant disputes their student status or argues the notice was improperly served.

Void period exposure. If possession is delayed past mid-August, the September reletting window closes. At Airhosts, we speak with landlords every week who are already re-evaluating their exposure to this exact scenario.

Compliance burden. Between HMO licensing requirements, the new possession procedures, and the ongoing responsibilities of managing a multi-tenant property, the administrative load on student HMO landlords has never been heavier.

The Financial Maths Are Shifting Too

Even when the cycle works perfectly, student HMOs in London typically sit empty for six to eight weeks over summer. That is roughly 15% of the year generating zero income. Factor in the cost of annual deep cleans, tenant find fees, inventory checks, and deposit administration, and net yields start looking considerably less impressive than the headline rent suggests.

A Simpler, Higher-Yielding Alternative Already Exists

While student HMO landlords navigate this new legal minefield, a growing number of London property owners are discovering that professionally managed short-term lets offer stronger returns with far fewer headaches.

Here is the contrast in plain terms. With a student HMO, you are now dependent on a single untested possession ground, locked into an annual cycle, exposed to summer voids, and carrying a heavy compliance burden. With a serviced accommodation model, your property earns income year-round, you retain full flexibility over your calendar, and there are no possession proceedings to worry about because short-term guests check out at the end of their booking.

London's short-term rental market remains exceptionally strong. Business travellers, relocating professionals, and tourists all drive consistent demand across every season. Properties in zones one through four regularly outperform their long-let equivalents by 30% to 60% on gross revenue when managed properly.

The key phrase there is "managed properly." Short-term lets do require active, professional management to hit those numbers. That is exactly where Airhosts comes in.

Why London Landlords Are Choosing Airhosts

Airhosts is a London-based short-term let management company built specifically for landlords who want high yields without the daily operational grind. We handle everything: listing optimisation, dynamic pricing, guest communications, professional cleaning, linen management, maintenance coordination, and full regulatory compliance.

For landlords currently running student HMOs, the transition is often far smoother than expected. Many HMO properties, particularly those with good locations and modern interiors, perform brilliantly as serviced accommodation. And because Airhosts manages the entire process from onboarding to ongoing operations, you do not need to become a hospitality expert overnight.

Our landlords benefit from year-round income, no void periods, no possession proceedings, and complete transparency through real-time reporting dashboards. It is the hands-off, high-yield model that the student HMO cycle used to promise but can no longer reliably deliver.

The Bottom Line

Ground 4A gives student HMO landlords a legal route to maintain their annual reletting cycle, but it is narrower, riskier, and more administratively demanding than the fixed-term model it replaces. For landlords who want predictable, strong returns from their London property without navigating untested legal territory every summer, professionally managed short-term lets are the clearest alternative.

If you are a London landlord wondering whether your property could earn more with less stress, get in touch with Airhosts today. We will give you an honest, no-obligation rental estimate and show you exactly what your property could achieve in the serviced accommodation market. Your property is too valuable to leave to legal uncertainty.
