There was always something of a myth about landlord and tenant law in England. The myth was that, provided you had a tenancy agreement and a Section 21 notice, possession was ultimately within your control.
Those of us practising in the field knew otherwise.
Even under the outgoing regime, the path to possession was littered with technical traps. A landlord who took a prohibited payment and failed to repay it would find their Section 21 notice invalid. A landlord relying on rent arrears would discover—often too late—that Ground 8 is only “mandatory” if pleaded and proved with precision. And even where everything was done correctly, a tenant who understood the system could delay matters significantly.
That was the position before 1 May 2026.
The Renters’ Rights Act 2025 does not simplify that system. It replaces it with something more structured, more prescriptive, and far less forgiving.
A System Rewritten
At its core, the Act does three things.
First, it abolishes assured shorthold tenancies.
Second, it abolishes fixed terms.
Third, it abolishes Section 21.
That combination is not incidental—it is transformative.
All tenancies are now periodic from the outset. There is no six-month or twelve-month term to expire. No contractual endpoint to rely upon. The tenancy continues indefinitely unless the tenant chooses to leave or the landlord can prove a statutory ground for possession.
In practical terms, time has been removed as a mechanism of control.
Possession: From Right to Argument
The removal of Section 21 is the headline change, but its real significance lies in what replaces it.
Possession is now entirely grounds-based, under an expanded Section 8 framework. Landlords must justify their claim. Sale, occupation, rent arrears, anti-social behaviour—each ground is available, but each comes with its own conditions, evidential requirements, and risks.
And critically, the timelines have shifted.
Where the old regime worked to a two-month benchmark under Section 21, the new regime frequently requires four months’ notice for sale or occupation grounds. That is before proceedings are issued, before the court timetable begins, and before enforcement is even contemplated.
The system has not just become more complex—it has become slower.
The Quiet Revolution: The Section 16D Statement
Perhaps the most significant change is not the abolition of Section 21, but the introduction of a new statutory duty.
Section 12 of the Act inserts section 16D into the Housing Act 1988, creating a requirement that landlords provide a written statement of terms and prescribed information.
This is not simply a rebranding of the tenancy agreement.
The statement must include:
- the terms of the tenancy (whether formally agreed or otherwise recorded);
- prescribed information about the tenancy, the property, the parties, and their respective rights;
and, importantly, it may include a statement that the landlord wishes to rely on certain statutory grounds for possession.
That last point is easily overlooked. It should not be.
The legislation expressly links the inclusion—or omission—of those grounds in the section 16D statement to the landlord’s ability to rely on them later. The cross-references to sections 16E and 16I make clear that failure at this stage may have consequences when serving a possession notice.
In other words, this is not just administrative compliance. It is foundational to enforcement rights.
The Information Sheet: A Familiar Trap, Reintroduced
Alongside section 16D sits a more practical but equally important requirement: the statutory information sheet.
Landlords must now ensure:
- that the document is provided at the outset of every new tenancy; and
- that it is served on existing tenants by 31 May 2026.
This will feel familiar to practitioners who recall the “How to Rent” requirements. The difference is context.
Under the old regime, failure to serve prescribed documents invalidated Section 21. Under the new regime, there is no Section 21. The consequence is not that one route is blocked—it is that the entire possession framework becomes harder to navigate.
It is, in effect, a new compliance gateway.
The End of Renewal—and of Leverage
Under the previous system, landlords retained a degree of control through the renewal process.
A fixed term would end. A new agreement would be negotiated. Rent could be increased. Terms could be revisited.
That mechanism has gone.
There is no renewal. The tenancy continues automatically.
Rent increases are now governed by statute—limited to once every twelve months and subject to challenge. The landlord cannot use the end of a term as leverage, because there is no end of term.
The relationship becomes continuous, not episodic.
Rent and the Market: Controlled by Process
The Act stops short of formal rent control, but it introduces something functionally similar.
Landlords must advertise a fixed rent. They cannot invite or accept bids above that figure. The increasingly common practice of competitive bidding is prohibited.
During the tenancy, increases must follow the statutory route. They are open to scrutiny. They are no longer a matter of contractual discretion.
The market remains, but it operates within defined procedural limits.
Discrimination: The Closing of Old Loopholes
The Act also addresses practices that have long existed at the margins of the sector.
Section 36 renders ineffective lease terms that seek to:
- prevent tenants from having children in the property; or
- exclude tenants based on their benefits status.
Importantly, this operates up the chain. Superior lease provisions cannot be used to justify discriminatory restrictions at the sub-tenancy level.
This is not merely a policy statement—it is a direct intervention in the contractual freedom of landlords.
Pets: From Prohibition to Reasonableness
The Act also reshapes the position on pets. Tenants are now entitled to request permission to keep a pet, and landlords must not unreasonably refuse. Blanket prohibitions are no longer tenable. Refusals will need to be justified by reference to legitimate factors—such as superior lease restrictions, building regulations, or a real risk of damage or nuisance—and may be conditioned on safeguards such as appropriate insurance. What was once a matter of discretion becomes a question of reasonableness, and therefore, a potential point of dispute.
A System That Assumes Litigation
One of the most striking features of the new regime is what it assumes.
Under the old system, Section 21 often allowed disputes to be resolved without the court engaging with the underlying merits.
Under the new system, that is no longer possible.
Every possession claim requires:
- a valid ground;
- a compliant notice;
- adherence to extended notice periods;
- evidence capable of withstanding scrutiny.
Litigation is no longer the exception. It is the mechanism.
The Reality for Landlords
It is tempting to view these changes in isolation: Section 21 is gone; notice periods are longer; compliance requirements have increased.
But taken together, they amount to something more fundamental.
The landlord is no longer operating within a largely contractual framework, supplemented by statutory rules. They are operating within a statutory system that governs the contract from start to finish.
Errors at the outset—failure to serve the section 16D statement correctly, failure to provide the information sheet by 31 May 2026, failure to comply with rent-setting requirements—are no longer irritants. They are structural weaknesses.
And without Section 21, there is no fallback.
Conclusion: Precision Is Now the Price of Possession
The Renters’ Rights Act 2025 does not remove the landlord’s ability to recover possession. But it does change the terms on which that ability is exercised.
Possession is no longer a right that can be invoked with notice. It is a remedy that must be justified, prepared, and proved.
The practical message is simple.
What was once a system that tolerated informality—albeit at risk—has become one that demands precision. From the initial statement of terms under section 16D, to the service of the information sheet by 31 May 2026, to the identification and proof of a statutory ground, every stage now matters.
Landlords who adapt will continue to operate successfully.
Those who do not will find that the difficulty of obtaining possession has not merely increased—it has become determinative.
On a personal note, this is not merely an abstract legal shift. My own family has been involved in the property rental business since the 1960s, and I practise as a barrister specialising in property and landlord and tenant law. Seen through both lenses—commercial and legal—this legislation marks the end of a more informal era. The private rented sector has long operated on a mixture of contract, custom, and experience. That model has now been replaced by one of statutory control and procedural discipline.
For better or worse, the message is clear: the margin for error has gone.
