Section 21 (the no-fault possession route that allowed landlords to recover a property without providing a reason) was abolished on 1 May 2026 under the Renters' Rights Act 2025. Abolished 1 May 2026
This is the most significant change to residential possession law in thirty years. Since the introduction of assured shorthold tenancies in 1988, the no-fault route had been the primary mechanism through which landlords ended tenancies: straightforward, procedurally clean, and, provided compliance prerequisites were met, largely predictable. That route no longer exists. Every possession claim in England now requires a statutory ground under Section 8 of the Housing Act 1988, and every claim must survive greater court scrutiny than was previously required.
Any Section 21 notice served on or after 1 May 2026 is invalid. Landlords who served valid Section 21 notices before 1 May 2026 had until 31 July 2026 to file court proceedings — after that date, any unexercised notice lapsed and Section 8 is the only route. For all possession proceedings from this point, Section 8 applies.
How Do the Section 8 Grounds Actually Work?
Section 8 grounds are statutory — they are set out in Schedule 2 of the Housing Act 1988, as amended by the Renters' Rights Act 2025. Each ground has a specific basis, a notice period, and either mandatory or discretionary application. Understanding the distinction between mandatory and discretionary grounds is critical, because it determines the level of certainty a landlord can expect from a court application.
| Ground | Basis | Type | Minimum Notice |
|---|---|---|---|
| Ground 1 | Landlord or close family intends to occupy as principal home | Mandatory | 4 months |
| Ground 1A | Landlord intends to sell the property | Mandatory | 4 months |
| Ground 6 | Landlord intends to demolish or substantially redevelop | Mandatory | 4 months |
| Ground 7A | Serious criminal or anti-social behaviour | Mandatory | Immediate |
| Ground 8 | At least 3 months' (or 13 weeks') rent arrears at service and hearing | Mandatory | 4 weeks |
| Ground 10 | Some rent arrears (below Ground 8 threshold) | Discretionary | 4 weeks |
| Ground 11 | Persistent late payment of rent | Discretionary | 4 weeks |
| Ground 12 | Breach of a tenancy obligation | Discretionary | 2 weeks |
| Ground 14 | Nuisance, annoyance, or anti-social behaviour | Discretionary | Immediate |
| Ground 17 | Tenant induced landlord to grant tenancy by false statement | Discretionary | 2 weeks |
For mandatory grounds, a court must grant possession if the ground is proven. For discretionary grounds, the court considers whether it is reasonable to grant possession even where the ground is established — adding a layer of judicial assessment that makes the outcome less certain and the evidential standard effectively higher.
What Evidence Do You Need for the Most Common Grounds?
Ground 8 (rent arrears) is the ground most frequently relied upon in practice, and the evidence requirements are specific. The arrears must exist both at the date the Section 8 notice is served and at the date of the court hearing — and must be at least three months throughout. If a tenant reduces arrears below the statutory threshold between notice and hearing, Ground 8 falls away, and the claim must be reconstituted on a discretionary ground — significantly weakening the landlord's position. Note also that arrears caused solely by Universal Credit payment delays cannot be used to satisfy the Ground 8 threshold.
A court-ready rent schedule should show: the tenancy start date, every rent payment due, every payment received (with date and amount), and the running balance at each point. This document should be maintained continuously from the moment rent first falls due — not assembled retrospectively when arrears become a problem. Tribunals and courts give significantly more weight to contemporaneous records than to summaries produced at the time of the claim.
For Ground 14 (nuisance and anti-social behaviour), evidence must document the specific incidents: dates, times, descriptions, witnesses where available, and any communications between the landlord and tenant addressing the behaviour. Police reports, neighbour statements, and local authority correspondence all strengthen the position. A landlord who can demonstrate a pattern of reported incidents, formal warnings, and continued behaviour is in a substantially stronger position than one who can only describe conduct verbally. Where conduct is serious enough to meet the criminal threshold, Ground 7A provides an immediate mandatory route.
How Does the Loss of Section 21 Change How Landlords Should Manage Tenancies?
The operational implication of Section 21's abolition extends beyond possession procedure. The design of no-fault possession allowed landlords to tolerate compliance gaps, relationship difficulties, and procedural ambiguities — because if things deteriorated badly enough, Section 21 offered an exit that did not require proof of wrongdoing. That safety net is gone.
The practical response is to treat every tenancy as if it must be defended on its merits from the outset. Compliance records must be complete, because compliance failures now carry no possession-route backstop. Rent accounts must be meticulous, because Ground 8 depends on a provable arrears position at a specific date. Communication records must be maintained, because Ground 14 requires documented evidence of conduct. Inventories and inspection reports must be thorough, because property condition disputes are decided on contemporaneous evidence.
This is not a pessimistic framing. Landlords who manage tenancies professionally, maintaining complete records, responding promptly to maintenance obligations, and tracking compliance continuously, are better positioned under the Section 8 regime than under Section 21, because their operational discipline generates the evidence base that makes ground-based possession reliable. The landlords who are exposed are those who relied on procedural convenience as a substitute for robust management.
