The first students to sign tenancies under the Renters’ Rights Act are about to collect their keys, and the market they enter no longer runs on the academic calendar. The Act’s first phase took effect in England on 1 May 2026, ending Section 21 and converting most private student tenancies to assured periodic tenancies with no fixed end date.
For student HMO landlords the consequence is blunt. Possession for the 2027-28 intake now depends on a ground with hard statutory dates, and missing them sets the cycle that underpins student yields back a full year.
The academic year no longer sets the tenancy
An assured periodic tenancy runs until the tenant ends it or the landlord makes out a valid possession ground. Tenants can serve notice at any point: agreements can demand no more than two months, less if agreed in writing.
In a joint tenancy, notice from one sharer will usually end the tenancy for the whole house. A group of four can become a void in June because one of them finished exams in May.
Agreed swaps survive where the landlord and the outgoing, incoming and remaining tenants all consent. What cannot be contracted away is the mid-year departure that leaves a room, or a whole house, empty when no student is looking.
Ground 4A and who qualifies
The route back to the September cycle is Ground 4A, a mandatory ground allowing a qualifying student HMO to be recovered and re-let to a new group of full-time students each year. Government guidance for landlords is clear it does not cover every student property.
The conditions are cumulative: an HMO, normally at least three unrelated tenants sharing a kitchen, bathroom or toilet; let to full-time students; an intention to re-let to another group of full-time students; written notice to tenants before the tenancy begins that Ground 4A may be relied on; and a tenancy agreed no more than six months before its start.
In a joint tenancy, every tenant must be a full-time student when it is granted, or the landlord must reasonably believe they will become one during it. On individual room agreements it works only against tenants who meet the student test, as the National Residential Landlords Association’s analysis sets out. One or two sharers normally fall outside the HMO definition, and outside Ground 4A with it.
The dates that decide the 2027-28 letting
Under the standard rules, a Ground 4A notice must give at least four months, and possession must be required between 1 June and 30 September inclusive. A landlord who wants possession on 1 June 2027 must serve by 1 February 2027; later dates still need four clear months.
The six-month signing restriction bites at the other end. An agreement for a September 2027 move-in cannot be concluded more than six months before its start date, which means March 2027 at the earliest and ends the traditional race to sign next year’s group before Christmas.
Transitional arrangements eased the changeover. For tenancies that began before 1 May 2026, landlords could serve Ground 4A notices between 1 May and 31 July 2026 with two months’ notice rather than four; notices validly served then can still support possession up to 30 September 2026.
That route has closed. A new notice needs the full four months, so landlords who did not use it are unlikely to regain possession under Ground 4A in what remains of the 2026 window. Other grounds may fit particular cases; the prudent assumption is that planning now points at summer 2027.
Advance rent, guarantors and the PBSA carve-out
The Act has also rewritten the cash flow of a student let. Rent cannot be required or accepted before the agreement is entered into, and once it is signed, at most one month’s rent can be required before the tenancy starts. Tenants can volunteer more during the tenancy; it can never be a condition of securing the property.
That lands hardest on international students without a UK guarantor, who typically offered several months upfront and are a segment the market is building new products for. Guarantor services and insurance-backed products are the lawful routes; conditioning a tenancy on advance rent is not.
Not every student is covered. University halls usually run on licences or common law tenancies, and privately operated purpose-built student accommodation can stay outside the periodic regime where the provider belongs to and follows an approved code of practice, preserving academic-year fixed terms even as parts of the PBSA sector contend with rising vacancies.
For HMO investors the conclusion is unsentimental. Demand remains deep and the market faces a projected shortfall of student rooms, but the houses that fill each September will belong to landlords who served notice the previous winter and signed the next group at the right moment in spring.
