Student lets used to be the simplest part of the private rented sector. Fixed-term tenancy, academic year, Section 21 as the backstop if a group didn't leave on time. That simplicity is gone. The Renters' Rights Act carved out a specific, narrow mechanism for student HMOs — and left a significant category of student accommodation with no equivalent route at all.

This edition covers what Ground 4A actually requires, the critical 31 May 2026 deadline many landlords may have already missed, why a 2-bedroom student flat is treated completely differently from a 3-bedroom student house, and what that gap means in practice.

Student accommodation in England now falls into three distinct regulatory categories, and confusing them is the single biggest risk in this area.

University-owned accommodation and true halls of residence — exempt from the Act entirely. Students here have common law tenancies, not assured shorthold tenancies, and are unaffected by any of this.

Purpose-Built Student Accommodation (PBSA) run by private companies — exempt from the Act, provided the operator complies with an approved code of practice such as the ANUK/Unipol Code. This exemption is not automatic or retrospective — existing tenancies in place up to the end of the 2025/26 academic year don't automatically benefit, though they do get the transitional version of Ground 4A described below.

Everyone else — HMOs and 1-2 bedroom student lets in the ordinary private rented sector. This is the category that includes most landlords reading this newsletter, and it's the category with the least protection under the new framework.

Ground 4A is a mandatory ground that allows landlords of HMOs let to full-time students to recover possession at the end of the academic year, specifically so the property can be re-let to a new group of students for the next year.

This is genuinely useful — it recreates, within the Section 8 framework, the academic-year cycle that fixed-term tenancies and Section 21 used to provide automatically. But it comes with conditions that are considerably more demanding than the old system, and missing any one of them means the ground simply isn't available.

The conditions, all of which must be met:

The property must be an HMO with three or more bedrooms. Ground 4A is specifically restricted to properties meeting the HMO definition — three or more unrelated tenants sharing facilities. A 1 or 2 bedroom student let does not qualify, regardless of how clearly it's marketed and understood as student accommodation.

All tenants must be full-time students. The tenants must meet the "student test" when the tenancy is entered into — either genuinely full-time students, or the landlord must have reasonable grounds to believe they will become full-time students. A mixed household — some students, some not — does not qualify.

Advance written notice is mandatory. Before entering into the tenancy, the landlord must have informed the tenants in writing of their wish to rely on Ground 4A to recover possession and relet to new students. This has to happen before the tenancy starts, not retrospectively.

The tenancy must not have been agreed too far in advance. The tenancy must not have been entered into more than six months before the tenants are entitled to possession of the premises. Given that student lettings are often agreed well before Christmas for the following September, this six-month restriction genuinely changes how the letting cycle needs to work.

Notice must fall within the academic year window. In order to rely on this ground, the landlord must provide a minimum of four months' notice, which must take effect between 1 June and 30 September in that year. This aligns Ground 4A specifically with the standard academic calendar — it isn't available as a general-purpose possession route outside that window.

If you have existing student tenants who moved in before 1 May 2026, you must provide written notification that Ground 4A applies by 31 May 2026. Miss this deadline and you cannot use Ground 4A for those tenancies.

This is a transitional provision worth checking urgently if it applies to you — in the same spirit as the 31 July court-filing deadline covered in Edition 32. For tenancies already in existence when the Act commenced, the landlord had one month — to 31 May 2026 — to serve written notice of intent to rely on Ground 4A, without needing to satisfy the usual six-month advance notice restriction for those existing tenancies specifically.

If you're a student HMO landlord with tenants who were already in occupation before 1 May and you haven't served that written notice, this deadline has now passed. Check today whether it was actioned — by you, your agent, or your solicitor.

This is the part of student letting reform that has received the least attention and causes the most practical difficulty.

Ground 4A is only applicable to HMO student lettings. Therefore, any landlords who let non-HMO properties to students — one or two bedroom properties or studio flats — will not be able to rely on this. These will be subject to the same regime as non-student private sector lettings.

In plain terms: a landlord letting a 2-bedroom flat to two students has no student-specific possession route at all. If those students want to stay indefinitely after their course ends, the landlord's only options are the same general Section 8 grounds available to any landlord — rent arrears, anti-social behaviour, sale, moving in — none of which are designed around, or naturally aligned with, an academic year cycle.

This may lead to a reduction in the availability of smaller properties in the private rented sector for the student market — landlords of 1-2 bedroom properties have a genuine incentive to reconsider whether letting to students remains viable, given they've lost the reliable annual turnover mechanism that HMO landlords retained through Ground 4A.

If you currently let a 1 or 2 bedroom property to students and have relied on the academic year as a natural exit point, that mechanism no longer exists in the way it used to. Worth thinking through now, before your next letting cycle, rather than discovering the gap when a tenant simply doesn't leave.

Student lettings have traditionally been agreed well before Christmas for the following September — landlords securing tenants for the next academic year as early as October or November, sometimes even earlier, to give certainty to both sides.

The six-month rule under Ground 4A works against that timeline directly. It is only available where the tenancy was not entered into more than six months in advance — this is likely to impact the way in which the private sector student accommodation market operates, since lettings are often agreed before Christmas for a September start, which is more than six months ahead.

If you want to rely on Ground 4A and you're currently agreeing tenancies in autumn or early winter for the following September, that timing needs to shift. Signing later in the letting cycle — inside the six-month window before the tenancy actually starts — protects your ability to use the ground later, at the cost of losing some of the early-booking certainty landlords have traditionally relied on.

Worth being precise about the boundaries. Ground 4A does not apply to mixed-occupancy HMOs where some tenants are students and some are not, and it does not apply to purpose-built student accommodation providers, who have their own separate exemption route.

A landlord running a 4-bedroom HMO with three students and one working tenant cannot use Ground 4A for that property at all — the ground requires every tenant to meet the student test. Mixed households fall back to the same general possession framework as any other shared house.

✅ Identify which category your property falls into — university-owned/PBSA (exempt), HMO with 3+ bedrooms all-student (Ground 4A available), or 1-2 bedroom / mixed occupancy (no student-specific route).

✅ If you have existing student tenants pre-dating 1 May 2026 — confirm written notice of intent to use Ground 4A was served by 31 May 2026. Check this today if you're not certain.

✅ For new student HMO tenancies — serve the written Ground 4A notice before the tenancy is signed, not after.

✅ Check your letting timeline against the six-month rule — agreeing tenancies more than six months before the start date may forfeit your ability to use Ground 4A later.

✅ Serve any Ground 4A notice within the June to September window — four months' notice, taking effect only in that period.

✅ Confirm the property genuinely meets the HMO threshold — three or more bedrooms, three or more unrelated tenants. A 2-bedroom student let doesn't qualify regardless of intent.

✅ Check for mixed occupancy — if any tenant in an HMO doesn't meet the student test, Ground 4A isn't available for that tenancy.

✅ If you let smaller student properties — plan now for the absence of any academic-year-specific possession route; the general Section 8 grounds are your only option.

Ground 4A gives HMO student landlords a genuinely workable route back to the academic-year cycle that used to run automatically — but it's narrower, more procedurally demanding, and less forgiving of timing mistakes than the fixed-term system it replaced. And for landlords letting smaller student properties, there's no equivalent mechanism at all.

The landlords who navigate this well are those who've mapped their entire student portfolio against these categories now — checked the 31 May deadline where relevant, adjusted letting timelines around the six-month rule, and accepted that 1-2 bedroom student lets sit in a genuinely different, less certain position going forward.
