Section 21 abolition in 2026: what landlords must do | August

Evictions in 2026: navigating the end of Section 21

Section 21 was abolished on 1 May 2026, ending more than three decades of no-fault eviction in England. From that date, a landlord can no longer end a tenancy simply by giving notice; every possession now rests on a specific legal ground proved through the courts under Section 8 of the Housing Act 1988. This guide explains what changed, the transition rules for any notice served before commencement, how possession works now, and the rules on illegal eviction that carry the heaviest penalties of all. Section 21 abolition is one part of the Renters' Rights Act, which reshaped the wider tenancy system at the same time.

What Section 21 was and why it has gone

For over thirty years Section 21 let a landlord end an assured shorthold tenancy without giving a reason, by serving a notice on Form 6A with two months' notice and, if needed, using an accelerated court procedure that usually avoided a hearing. The government abolished it to give tenants greater security and to remove the fear that raising a complaint about conditions might prompt a retaliatory eviction. For landlords the practical effect is a shift in mindset: ending a tenancy is no longer a matter of giving notice but of having, and being able to prove, a recognised ground. That single change is the one self-managing landlords most need to absorb, because it reshapes how a tenancy must be documented from the first day.

What changed on 1 May 2026

Three things changed together. Section 21 ended, so Section 8 became the only route to possession. Fixed terms were abolished and every assured shorthold tenancy became a periodic assured tenancy, rolling month to month. And the Section 8 grounds themselves were revised, with longer notice periods on the major grounds and a higher rent arrears threshold. The mechanics of all this sit in dedicated guides, covered below, but the headline is that possession is now slower, evidence-led and unforgiving of procedural error.

The transition: notices served before 1 May 2026

If you served a valid notice before commencement, you can still rely on it, but only within a limited window, and the deadlines are firm. A Section 21 notice served before 1 May 2026 remains valid and the tenancy stays an assured shorthold tenancy until proceedings conclude, but you must ask the court to issue proceedings by the backstop date. The same broad approach applies to a Section 8 notice served before commencement.

The 31 July 2026 backstop is the binding deadline for almost all pending Section 21 notices, reflecting the rule that proceedings must begin within the earlier of six months from service or three months from commencement. If you hold a pre-commencement notice you have not yet acted on, that date is the one to diarise.

How possession works now

With no-fault gone, possession runs through Section 8, and the detail lives in four companion guides. Every possession now rests on a specific legal ground, mandatory or discretionary, each with its own notice period and evidence requirements. Each ground is set out in a notice served on the current prescribed form, and how to serve a Section 8 notice correctly is a process in its own right. The claim then runs through the courts, and how long eviction now takes is considerably longer than the route it replaced, because the accelerated procedure has gone. Rent arrears remain the most common reason for possession and have their own combination of grounds and a route to recover the debt, set out in the guide to evicting tenants for rent arrears.

Illegal eviction: the line you must not cross

The costliest mistake a landlord can make is to take possession into their own hands. Recovering a property by any route other than the court process is illegal eviction, and it is far more serious than a failed possession claim. Changing the locks while a tenant is out, removing their belongings, cutting off utilities or pressuring them to leave are all offences, whether done deliberately or simply because a notice has expired and patience has run out. Only county court bailiffs, acting on a warrant, may remove a tenant.

Unlawful eviction and harassment are criminal offences under the Protection from Eviction Act 1977, carrying up to six months' imprisonment in the Magistrates' Court and up to two years and an unlimited fine in the Crown Court. The Renters' Rights Act added a further layer: a local authority can now impose a civil penalty of up to £40,000 as an alternative to prosecution, and a tenant or the authority can seek a rent repayment order of up to two years' rent, on top of any civil damages a court awards. The lesson is simple. However long the lawful process takes, it is always cheaper than the alternative.

What to do now: adapting to grounds-based possession

Because possession now turns on proving a ground, the work that protects a landlord happens long before any notice is served. Front-loaded referencing matters more than ever, since a reliable tenant is the best defence against ever needing the courts, and accepting a weak applicant to avoid a void can cost far more in a drawn-out possession claim. Records matter more too: a clean rent ledger, protected deposits, in-date safety certificates and a clear trail of correspondence are the evidence a court will expect, so it pays to keep your compliance current and to keep the evidence for a possession claim in one place rather than across email, paper and memory. Beyond that, the principles are unchanged: serve the right notice correctly, act promptly once a ground is met, and treat the tenancy as a long-term business relationship, because the tenancies that never reach court are the ones managed well from the start.

Frequently asked questions

Can I still use a Section 21 notice in 2026? 

No new Section 21 notice could be served on or after 1 May 2026, and the last date to serve one was 30 April 2026. If you served a valid notice before then and the tenant has not left, you must issue court proceedings by 31 July 2026 or the notice lapses.

What replaces Section 21? 

Section 8 of the Housing Act 1988. Every possession now requires a recognised ground, served by notice and, if the tenant does not leave, proved at a court hearing.

Can I evict a tenant without a court order? 

No. Taking possession by any other means is illegal eviction, a criminal offence that can also bring a civil penalty of up to £40,000 and a rent repayment order. Only court bailiffs may carry out an eviction.

Do I need to send my tenants anything because of the change? 

Yes. Existing tenants must be given the Renters' Rights Act Information Sheet 2026, with a deadline of 31 May 2026 and a penalty of up to £7,000 for missing it. If you want your records and compliance in order, you can start for free.

Key takeaways

Section 21 ended on 1 May 2026 and is not coming back. Possession now runs through Section 8 on a proven ground, takes longer, and demands evidence kept from the start of the tenancy. Any pre-commencement notice must reach court by 31 July 2026. Above all, never recover a property outside the court process, because illegal eviction is the one mistake whose cost dwarfs the inconvenience of the lawful route.
