For years, Section 21 has been one of the defining features of the private rented sector in England. Whether praised as a necessary route for landlords to regain possession or criticised as the legal basis for no-fault eviction, it has shaped the relationship between landlords, tenants and letting agents for decades. Now, with its abolition looming under the Renters’ Rights Act, the market is reacting in exactly the way many expected: by rushing to use it while it still exists.
Recent figures suggest that Section 21 evictions continued to rise during 2025, following a sharp jump the year before. On one level, that should not surprise anyone. When a long-standing legal mechanism is about to disappear, those who have relied on it will naturally look to use it before the door closes. But this rise is about far more than a short-term spike in notices. It is a sign of deeper anxiety in the market, uncertainty about how possession will work in future, and a growing shift in landlord behaviour that could have lasting consequences for the supply, cost and stability of rented housing across the UK.
Why landlords are moving now
The simplest explanation is that landlords are acting before the rules change.
Section 21 has traditionally allowed landlords to recover possession without having to prove fault, provided the correct process is followed and sufficient notice is given. That has made it a backstop option in a wide range of circumstances: where a landlord wants to sell, where they no longer feel comfortable continuing a tenancy, where the relationship has broken down, or where they want certainty without the cost and delay of relying on more contested legal grounds.
Once Section 21 is removed, the landscape changes fundamentally. Landlords will no longer be able to end tenancies through a no-fault route. Instead, they will need to rely on Section 8 and one or more specified legal grounds for possession. Those grounds are expected to include rent arrears, anti-social behaviour, damage to the property, and certain landlord circumstances such as wanting to sell or move family in. Even where those grounds exist, however, many landlords are concerned that the process will become more technical, more heavily scrutinised and more dependent on court efficiency than ever before.
That concern is driving behaviour today. For some landlords, the calculation is straightforward: if they are already considering selling, restructuring a portfolio, exiting the market or regaining possession for another reason, it feels safer to act under the current system than wait for an unfamiliar one.
The psychology behind the surge
The rush is not just legal. It is psychological.
Markets do not respond only to what the law says. They respond to what participants believe the law will mean in practice. In this case, many landlords see the loss of Section 21 not simply as a procedural change but as a reduction in control over a high-value asset.
Property owners are asking themselves difficult questions. What happens if a tenant stops paying and the Section 8 route is slower than expected? What happens if they need to sell quickly? What happens if the courts become clogged with possession claims? What happens if they make a mistake in the new process and have to start again?
Even where the new regime does provide routes to possession, the perception of risk matters. If landlords believe possession will become harder, slower or costlier, many will make defensive decisions before the reforms fully bite. That can mean serving notice now rather than later, becoming more selective about future tenants, or leaving the sector altogether.
Why the official numbers may understate the real picture
One of the most important points in the article is that official eviction or repossession figures likely capture only part of what is happening.
In many cases, when a tenant receives a Section 21 notice, they leave before the matter ever reaches court. That means the formal statistics do not necessarily show the full scale of disruption. Behind every recorded possession case may be a wider pattern of notices served, tenancies ended early, and households forced to move before legal action is completed.
That matters because the policy debate often centres on court data and possession claims, while the lived reality is broader. A rise in Section 21 usage does not just mean more cases in the system. It can also mean more instability in local rental markets, more households scrambling for alternative accommodation, and more pressure on councils already dealing with homelessness prevention and temporary housing demand.
Why this is happening across the sector, not just among “bad landlords”
It would be easy to frame the surge purely as a final wave of no-fault evictions by landlords trying to exploit a disappearing power. In some cases, that may be part of the story. But the fuller picture is more complex.
Many landlords are not rushing because they are acting unfairly; they are rushing because they are uncertain. They are looking at a market already under strain from tax changes, compliance burdens, mortgage costs, licensing requirements, rising repair bills and frequent regulatory change. For some, the abolition of Section 21 is arriving not in isolation but as the latest in a long series of measures that have made being a landlord feel more complex, less predictable and less commercially viable.
That does not mean reform is wrong. It does mean that reform has behavioural consequences. When confidence declines, exits rise. When exits rise, supply tightens. And when supply tightens in a market where demand remains high, tenants can end up paying the price through higher rents and fewer choices.
The role of letting agents in the middle
Letting agents are caught between competing pressures.
On one side are landlords seeking advice on whether to act now, how to regain possession lawfully, and how to prepare for a system that will rely more heavily on evidence-based grounds. On the other are tenants who may already feel insecure, anxious or confused about what the reforms mean for them.
The agents who navigate this period best will be those who focus on clarity and process. Landlords need to understand that acting hastily without legal compliance can create risk. Tenants need clear communication and proper notice. And both sides need realistic guidance about what will and will not change once the reforms take effect.
In the years ahead, good agents are likely to become even more valuable. As the possession framework becomes more rules-based and documentation-heavy, professional management, strong record keeping, tenancy support and early intervention on arrears or disputes will matter more than ever.
What the long-term consequences could be
The abolition of Section 21 is intended to improve tenant security. In principle, that should reduce arbitrary displacement and give renters greater confidence to settle, plan and stay in their homes. For many tenants, that will be a positive and overdue change.
But every major reform creates secondary effects. The long-term consequences for the private rented sector may include the following.
1. A more cautious landlord market
Landlords who remain in the sector are likely to become more risk-conscious. That may mean stricter affordability checks, more conservative tenant selection and less willingness to let to applicants with complex circumstances, patchy credit histories or limited guarantor support.
That would be an unintended consequence of a reform designed to improve fairness. If landlords feel possession is harder, they may try to reduce the chance of ever needing it.
2. Reduced supply in some parts of the market
Some landlords will decide the new balance of risk and reward no longer works for them. Those already considering a sale may accelerate their exit. Smaller landlords in particular may conclude that the compliance burden, financing environment and legal uncertainty are too much.
If enough landlords leave, rental supply will shrink further. In areas where demand is already intense, that could worsen affordability and competition for homes.
3. Greater reliance on Section 8 and the courts
The end of Section 21 does not remove the need for possession. It simply channels possession into a different route. That means Section 8 will become more important and court performance will become even more critical.
If the court system is not fast, consistent and adequately resourced, frustration will build quickly. Landlords may feel the law offers rights on paper but not in practice. Tenants may face longer, more adversarial disputes. Agents may be left managing drawn-out cases with increasing cost and stress for all involved.
4. A more professionalised sector
There is also a more positive possibility. The removal of Section 21 may push the sector toward better management standards, earlier dispute resolution, stronger documentation and more deliberate use of legitimate grounds for possession.
Over time, that could support a more professional rental market in which good landlords continue to operate successfully, poor practice is squeezed out, and tenants benefit from greater security and transparency.
But that outcome depends heavily on implementation. Reform alone does not guarantee improvement. The system around the reform must work.
5. Continued upward pressure on rents
If supply falls while demand remains strong, rents are unlikely to ease. In fact, one of the paradoxes of the current moment is that a reform designed to improve tenant protections may coincide with worsening affordability if it contributes to landlord exit or more cautious investment decisions.
Security of tenure matters, but so does access to housing in the first place. Policymakers will ultimately be judged not just on whether they abolish Section 21, but on whether tenants can still find decent homes at prices they can afford.
What happens next
The key issue now is not whether the sector can function without Section 21. It can. The real question is whether the replacement system will be trusted.
For landlords, trust means confidence that legitimate possession claims can be handled fairly and efficiently. For tenants, trust means confidence that they cannot be uprooted without a proper reason. For agents, trust means having a legal framework that is workable in practice, not just in theory.
That is why the current rush to serve Section 21 notices matters so much. It is not just a last burst of activity under an outgoing rule. It is a warning signal. It tells us that a large part of the market remains unconvinced about what comes next.
If the post-Section 21 regime is clear, balanced and supported by functioning courts, the sector may eventually stabilise and mature. If it is slow, unclear or poorly implemented, the consequences could include reduced supply, higher rents, more defensive landlord behaviour and a less flexible market overall.
Final thoughts
The rise in Section 21 usage ahead of abolition is a reminder that property law does not operate in a vacuum. Every reform sends signals, and the market reacts before the law fully arrives.
What we are seeing now is a sector trying to manage uncertainty. Some landlords are moving quickly to regain possession while they still can. Some are reviewing whether to stay in the market at all. Some are waiting to see whether the new Section 8 framework will genuinely protect their ability to recover property when there is a valid need.
For the private rented sector, the long-term consequences will depend less on the headline abolition of Section 21 and more on what replaces it in practice. Tenant security is a legitimate goal. But unless reform is matched by legal clarity, court readiness and renewed landlord confidence, the sector may end up more constrained, more expensive and more fragile than before.
