From 1 May 2026, Section 21 of the Housing Act 1988 ceases to exist. The 'no-fault' eviction route that landlords have relied on for nearly four decades is gone. No transition period. No opt-out. No exceptions for existing tenancies.
What replaces it is not new — Section 8 has always existed alongside Section 21 — but the way it works has been substantially rewritten by the Renters' Rights Act 2025. There are new grounds for possession, extended notice periods, a higher rent arrears threshold, and restrictions on when certain grounds can be used.
This guide covers every ground available to you, when each applies, the exact notice periods, and the practical steps to build a possession case that actually succeeds in court. This post is part of our complete Renters' Rights Act guide.

Why Section 21 Mattered — and Why Losing It Changes Everything
Section 21 allowed landlords to regain possession without giving a reason, provided they served a valid notice and followed the correct procedure. For many landlords, it was not primarily an eviction tool — it was a management tool. The ability to end a tenancy without needing to prove fault gave landlords a safety net for situations that were difficult to evidence: persistent low-level nuisance, relationship breakdown, gradual property deterioration.
That safety net is gone. Every possession claim from 1 May 2026 must be supported by a specific statutory ground under Section 8. If you cannot prove one of those grounds, the court will not grant possession. It does not matter how frustrated you are, how difficult the tenant is, or how badly you want to sell. Without a ground, you have no route.
Landlords must move from reactive management to documented, evidenced management. Your records, communication logs, and compliance documentation are now the foundation of any future possession case.
Section 8: How the Process Works
The Section 8 process follows a defined sequence. Getting any step wrong can invalidate the entire claim, delay proceedings by months, or result in costs being awarded against you.
Identify the ground
Determine which statutory ground (or grounds — you can cite multiple) applies to your situation. Each ground has its own conditions that must be met before you can serve notice.
Serve a Section 8 notice
This must be in the prescribed form, cite the correct ground(s), and give the correct notice period for each ground cited. If you cite multiple grounds with different notice periods, the longest period applies.
Wait for the notice period to expire
You cannot begin court proceedings until the full notice period has passed. Premature applications will be struck out.
Apply to the court
File a possession claim with the county court. You will need your Section 8 notice, evidence supporting your ground(s), the tenancy agreement, and proof of service.
Attend the hearing
For mandatory grounds, the court must grant possession if you prove the ground is satisfied. For discretionary grounds, the court also considers whether it is reasonable to grant possession — this is where evidence quality matters enormously.
Enforce the order
If the tenant does not leave by the date specified in the possession order, you must apply for a warrant of eviction executed by county court bailiffs. You cannot lawfully change the locks or remove the tenant yourself.
Mandatory vs Discretionary: The Distinction That Decides Your Case
Mandatory grounds require the court to grant possession if you prove the ground is made out. The judge has no discretion — if the conditions are met, possession is granted. These are your strongest grounds.
Discretionary grounds allow the court to grant possession, but only if it also considers it reasonable to do so. The judge weighs the circumstances: the severity of the breach, the tenant's conduct, whether they have dependants, the impact of eviction. This is where weak documentation kills your case. If you cannot demonstrate a clear pattern of breach with dates, evidence, and communications, the court may decline possession even if the ground technically applies.

The Evidence Standard: Why Documentation Is Now Your Most Valuable Asset
Under Section 21, you did not need to justify your reasons. Under Section 8, every claim lives or dies on evidence. District judges in possession hearings will scrutinise:
Communication records. Every complaint, every warning, every request for action — in writing. Verbal conversations not followed up in writing do not exist as far as the court is concerned.
Inspection reports. Dated photographs, formal inspection notes, contractor assessments. For Ground 12 property damage claims, you need before-and-after evidence.
Rent payment records. A complete ledger showing every payment, every late payment, every missed payment, with dates. For Ground 8, you must prove three months' arrears at two separate points in time.
Formal notices and warnings. Evidence that you gave the tenant reasonable opportunity to rectify breaches before escalating. Courts expect proportionality.
Compliance documentation. Gas safety certificate, EICR, EPC, deposit protection confirmation, and How to Rent guide must all be in order. Compliance gaps can be used against you and may prevent you from serving a valid notice at all.
This is the operational reality of post-Section 21 landlording. You are building a legal file from the first day of every tenancy. If you do not have a system for capturing, dating, and storing this information, you need one before 1 May.

Five Mistakes That Will Destroy Your Possession Claim
These are not theoretical. They happen in court regularly and result in cases being struck out, delayed by months, or dismissed entirely.
1. Serving the wrong form or citing the wrong ground
The Section 8 notice must be in the prescribed form and must correctly cite the ground(s) you are relying on. A notice that cites Ground 8 when the arrears are actually two months and three weeks — not three full months — is invalid. You cannot amend it retrospectively.
2. Starting proceedings before the notice period expires
If you serve a notice requiring four months and apply to the court after three months and 28 days, the application is premature and will be struck out. Count the days carefully.
3. Relying on verbal evidence for discretionary grounds
Telling the judge 'the tenant is always causing problems' without dated written evidence is worthless. The court needs a documented trail: complaint letters, formal warnings, photographs, neighbour statements, police report numbers.
4. Having your own compliance gaps
If your gas safety certificate has lapsed, your deposit is not protected, or you failed to serve required prescribed information, the court may refuse to make a possession order. Your compliance must be watertight before you begin proceedings.
5. Not citing multiple grounds
You can cite more than one ground in a single Section 8 notice. If a tenant has rent arrears and has also breached the tenancy agreement, cite Ground 8 (or 10) and Ground 12. If Ground 8 fails because the tenant pays down below the threshold, Ground 12 or Ground 11 may still succeed. This is basic litigation strategy — use it.
The Grey Zone: Difficult Tenants Who Are Not Technically in Breach
This is the uncomfortable truth about losing Section 21. Some situations do not fit neatly into the Section 8 grounds. A tenant who pays on time, does not damage the property, but is unpleasant, uncommunicative, or makes your life difficult in ways that fall short of a tenancy breach — there is no ground for that.
The government's position is clear: landlords should not be able to remove tenants from their home simply because the relationship is poor. The Act is designed to protect tenants from arbitrary eviction, and that protection necessarily means some frustrating situations will not have a possession route.
Document everything in case the behaviour escalates to a level that constitutes a breach or nuisance (Grounds 12 or 14). Ensure your tenancy agreement is specific enough that the behaviour you find problematic is actually prohibited. Manage the relationship proactively through clear communication and formal processes. Having an intermediary handle difficult tenant relationships removes personal friction and creates a documented communication trail.
The Transition: Section 21 Notices Already Served
If you served a valid Section 21 notice before 1 May 2026, it does not automatically become invalid. However, you must request the court to issue a claim form for possession proceedings by 31 July 2026. If you have not done so by that date, the notice lapses entirely. There is no extension and no appeal.
If you served a Section 21 notice in early 2026, you have a limited window to act on it. Do not assume you can begin proceedings at any point after 1 May. The 31 July deadline is final.
What to Do Right Now
Build your documentation system
If you do not have a formalised system for recording tenant communications, complaints, inspections, and maintenance requests — with dates, evidence, and follow-up actions — create one now. This is not administrative overhead; it is your legal defence capability.
Review your tenancy agreements
Ensure your agreements are specific about prohibited activities, maintenance obligations, and communication expectations. Vague clauses are unenforceable. If the agreement does not prohibit the behaviour, Ground 12 does not apply.
Audit your compliance
Gas safety, EICR, EPC, deposit protection, prescribed information, How to Rent guide. All must be current. Any gap undermines your ability to bring possession proceedings successfully.
Address existing breaches now
If you have tenants currently in breach of their tenancy, do not wait until after 1 May to act. Document the breach, issue formal written warnings now, and consider whether it is appropriate to begin proceedings while Section 21 remains available.
Consider professional management
The compliance, documentation, and legal process requirements under the new regime are substantially more demanding than what most self-managing landlords have dealt with. A managing agent with systems for tracking obligations, generating evidence, and managing Section 8 processes adds significant risk reduction.

Frequently Asked Questions
Get Ready Before Section 21 Disappears
The transition from Section 21 to Section 8 is not just a legal change — it is an operational change. It requires different processes, better documentation, stronger tenancy agreements, and more rigorous compliance. Landlords who prepare now will manage this smoothly. Those who do not will find themselves unable to regain possession when they need to.
