Section 21 is gone. From 1 May 2026, the no-fault notice that landlords in England leaned on for more than thirty years can no longer be served, and the route to recovering a property now runs entirely through Section 8 of the Housing Act 1988. If you let residential property and you have only ever ended a tenancy by handing over a two-month notice with no reason attached, the ground beneath that habit has shifted. This guide walks through what changed under the Renters' Rights Act 2025, how the reformed Section 8 process actually works in practice, and the points where a careless notice now collapses a possession claim before it reaches a hearing.
For most landlords the practical question is not whether the reform happened but how to get a tenant out lawfully when there is a genuine reason to. That answer now lives in the grounds, the notice periods and the evidence you can put in front of a county court judge.
What Section 21 was, and why its removal matters
Section 21 let a landlord end an assured shorthold tenancy without giving any reason, provided the deposit was protected, the right documents had been served and the notice itself was correctly drafted. It was fast, it was mechanical, and it did not require the landlord to prove anything beyond compliance. That is precisely why the government targeted it. The reform replaces the old assured shorthold tenancy with a single periodic assured tenancy that runs with no fixed end date, and it strips out the no-reason exit entirely.
The change is not cosmetic. Under the old regime a landlord who wanted the property back simply waited out the fixed term and served notice. Now every possession claim must rest on a stated, provable ground. A landlord can no longer end a tenancy merely because the fixed term has expired, for the simple reason that fixed terms have stopped existing for residential lettings. The whole architecture of how you end a tenancy has moved from "no fault needed" to "name your reason and prove it".
One transitional point still bites. Section 21 notices served on or before 30 April 2026 remain valid under the old rules, but only if court proceedings were issued in time under the transitional arrangements. Anything served from 1 May onward is simply ineffective. If you are reading this after the switchover, that door is closed.
The legal framework after the Renters' Rights Act 2025
The Renters' Rights Act 2025 received Royal Assent on 27 October 2025, and its central tenancy reforms commenced on 1 May 2026. From that date almost all existing assured and assured shorthold tenancies converted automatically into periodic assured tenancies, fixed terms fell away, and Section 21 of the Housing Act 1988 ceased to be available. The Act works by amending the Housing Act 1988 rather than replacing it, so the familiar Schedule 2 grounds remain the backbone of possession, now substantially rewritten and expanded.
Possession therefore runs exclusively through Section 8. The landlord serves a notice citing one or more statutory grounds, waits out the relevant notice period, and if the tenant does not leave, applies to the county court for a possession order. Grounds split into two families. Mandatory grounds oblige the court to grant possession once the ground is proved, while discretionary grounds leave the judge to decide whether possession is reasonable in all the circumstances even where the facts are made out. That distinction governs everything about how you build a claim, because a mandatory ground with clean evidence is a far stronger position than a discretionary one that invites the court to weigh the tenant's circumstances against yours.
Two structural protections sit on top of the grounds. New tenancies carry a protected period of twelve months during which the landlord cannot use the sale or moving-in grounds, and several non-fault grounds now require four months' notice rather than the old two. Government guidance, new prescribed forms and the detail of the reformed grounds are set out in the official material on the GOV.UK guidance on the Renters' Rights Act and assured tenancies, which is the source to check before serving anything, since the prescribed wording is unforgiving.
There is also a deadline unconnected to any eviction. Every landlord had to give existing tenants the official information sheet by 31 May 2026, with penalties of up to £7,000 per tenancy for failing to do so. It is worth confirming you discharged that obligation, because a tribunal that finds you ignored one statutory duty tends to look hard at the others.
The Section 8 grounds you will actually use
Most landlords reach for a handful of grounds, and it pays to know them precisely. For landlords who want to sell, the new Ground 1A allows possession where you intend to sell the property, on four months' notice, and it cannot be used in the first twelve months of the tenancy. Ground 1 covers the landlord or a close family member moving in to occupy the property as their only or principal home, again on four months' notice and again barred during the protected period. Both grounds carry re-letting restrictions afterwards: having recovered the property to sell or to live in, you cannot quietly put it back on the rental market for a restricted window, and a tenant who spots a fresh listing has a real complaint.
Rent arrears remain the most common trigger. The mandatory Ground 8 now requires three months' arrears at both the date of the notice and the date of the hearing, raised from the old two-month threshold, with the notice period extended to four weeks. A new Ground 8A tackles tenants who repeatedly let arrears build and then clear them just before a hearing, by allowing possession where arrears of two or more months arose on three separate occasions within three years. Universal Credit payment delays are now stripped out of the arrears calculation, so a tenant whose benefit ran late is not pushed over the threshold by the state's own slowness. The discretionary arrears grounds, where some rent is owed or rent has persistently been paid late, survive but leave the decision to the judge.
Anti-social behaviour grounds also continue, and in serious cases the notice period can be very short. The practical lesson across all of these is the same: the ground you choose dictates the notice period, the evidence you need and whether the court has any discretion at all, so the choice is the first and most consequential decision in the whole process. Getting it wrong does not just slow you down, it can invalidate the notice.
How possession works step by step
The sequence is now unforgiving in its formality. First you identify the correct ground and confirm it is available, which for the sale and moving-in grounds means checking you are past the twelve-month protected period. Next you complete the prescribed notice, the current Form 3A for assured tenancies, citing every ground you intend to rely on and stating the arrears or facts accurately, because a court will hold you to what the notice says. Then you serve it and let the notice period run, which ranges from a fortnight for the most serious grounds up to four months for the non-fault routes.
If the tenant does not leave when the notice expires, you apply to the county court for a possession order. For mandatory grounds with solid evidence, the accelerated reality is still that court time is the bottleneck: claims commonly take several months from issue to a repossession, and recent figures put the median well beyond half a year. A possession order does not itself remove anyone. You must never change the locks or force a tenant out yourself, because doing so is a criminal offence under the Protection from Eviction Act 1977; if the tenant stays past the order you apply for a warrant and the work is done by county court bailiffs or, in some cases, High Court enforcement agents.
The thread running through every stage is documentation. Rent ledgers that reconcile to the penny, gas safety and electrical certificates, the deposit protection paperwork and a record of communications all decide whether a contested hearing goes your way. A judge faced with a tidy bundle and a vague tenant defence reaches for the possession order; faced with a sloppy bundle, the same judge adjourns.
Generating a compliant Section 8 notice
Because the notice now carries the entire legal weight of the eviction, the wording and the cited grounds have to be right the first time. This is where Captain.Legal earns its place: the Section 8 notice template for UK landlords walks you through the questions that actually determine validity, rather than handing you a blank form to misfill. You answer plain questions about the tenancy, the ground you are relying on and the arrears or circumstances behind it, and the generator assembles the statutory wording, applies the correct notice period for that ground, and outputs a document you can serve.
The same logic applies upstream, before any dispute arises. A tenancy that was set up properly is far easier to end lawfully, which is why the assured shorthold tenancy agreement, now drafted for the post-reform regime, and the deposit receipt with prescribed information template matter as much as the notice itself: a deposit that was never protected, or prescribed information that was never served, can sink a possession claim long before the grounds are even examined. Every document downloads in both Word and PDF, so you can edit the detail and keep a signature-ready copy, and the templates track the current legislation rather than the version that applied before 1 May 2026. For a landlord handling possession without a solicitor, the value is in not having to reverse-engineer the prescribed wording from scratch under time pressure.
Where landlords get it wrong
The mistakes are predictable and almost all of them are fatal to the claim. The most common is reaching for Section 21 out of habit and serving a notice that no longer exists in law; from 1 May 2026 it does nothing at all. A close second is citing the wrong ground or the wrong notice period, since each ground carries its own minimum and a notice that gives too little time is simply void. Landlords also routinely understate or overstate arrears on the notice, then find the figure does not match the ledger at the hearing, which hands the tenant a defence.
The protected period catches out landlords who want to sell or move in within the first year and do not realise Ground 1A and Ground 1 are blocked until month twelve. The re-letting restriction trips up those who recover a property on the sale ground and then quietly re-advertise it, a step that is both a breach and easy for an aggrieved former tenant to evidence. And underneath all of these sits the documentation failure: an unprotected deposit, a missing gas safety certificate, prescribed information never served, or the new information sheet ignored past the 31 May 2026 deadline. Any one of them can turn a winnable possession claim into an adjournment or an outright dismissal, which is why the careful landlord treats paperwork as the foundation of the eviction rather than an afterthought to it.
Frequently asked questions
Is a Section 8 notice legally valid if I prepare it myself without a solicitor?
Yes. A Section 8 notice prepared by a landlord is fully valid in law provided it uses the prescribed form, cites genuine statutory grounds and gives the correct notice period for each ground. There is no requirement to instruct a solicitor to serve notice. What matters is accuracy: the form, the grounds, the arrears figures and the dates must all be right, because the county court will hold you to exactly what the notice says. Using a structured template that applies the current prescribed wording removes most of the risk of a technical error that would otherwise make the notice ineffective.
Can I still use a Section 21 notice after 1 May 2026?
No. Section 21 was abolished on 1 May 2026 and no Section 21 notice can be served from that date onward. Notices served on or before 30 April 2026 remained valid under the old rules, but only where court proceedings were issued within the transitional time limits. After the switchover, every possession claim in England must rely on a Section 8 ground under Schedule 2 of the Housing Act 1988. Serving an old-style no-fault notice now achieves nothing and simply wastes the notice period.
What notice period must I give under Section 8?
It depends entirely on the ground. The non-fault grounds, such as selling the property under Ground 1A or moving in under Ground 1, require four months' notice. Rent arrears under Ground 8 now carry four weeks. The most serious anti-social behaviour grounds can require as little as two weeks, and in the gravest cases the court can dispense with much of the wait. Because each ground sets its own minimum, a notice that gives too little time is void, so the period has to match the ground you actually cite.
How long does the whole eviction take in practice?
Longer than most landlords expect, because the court stage is the bottleneck. After the notice period expires you apply to the county court, and recent statistics show the median time from claim to repossession running well beyond six months. A contested hearing, an adjournment for further evidence or the need to instruct bailiffs all add time. Starting early, choosing a mandatory ground where you can and arriving with a clean evidence bundle are the levers that genuinely speed things up.
Can I evict a tenant simply because the fixed term has ended?
No, and this is the heart of the reform. Fixed terms no longer exist for residential tenancies in England; tenancies are now periodic from day one. There is no longer any moment at which the tenancy "ends" and the landlord can take possession without a reason. You can only recover the property by establishing a Section 8 ground, whether that is arrears, anti-social behaviour, an intention to sell or an intention to move in. The expiry of a term is not a ground.
In what format can I download a Section 8 notice?
Documents generated on the platform download in both Word and PDF. The PDF is ready to print and serve, while the Word version lets you adjust details before finalising. The tenancy and possession documents in the UK real estate category all follow the same dual-format approach, so you keep an editable working copy alongside a clean signing copy.
What happens if I get the deposit protection wrong?
It can derail the whole claim. Deposit protection failures and missing prescribed information were already grounds for challenge under the old regime, and they remain a serious vulnerability. A judge examining a possession claim will look at whether you complied with your wider statutory duties, and an unprotected deposit signals carelessness across the board. Protecting the deposit in an approved scheme and serving the prescribed information correctly is foundational, which is why landlords increasingly sort the paperwork at the start of the tenancy rather than scrambling once a dispute begins.
Does the Renters' Rights Act apply across the whole UK?
No. The Section 21 abolition and the reformed Section 8 regime apply to England only. Wales, Scotland and Northern Ireland operate their own separate rental laws and possession procedures, which were not changed by this Act. If your property is outside England, the grounds, notice periods and forms described here do not apply, and you should work from the rules of the relevant nation instead.
