Section 21 abolished: what landlords need to know

Section 21 no-fault evictions ended for private tenancies on 1 May 2026, and the window for using older notices closed on 31 July 2026. To regain possession now, you serve a Section 8 notice on a specific ground and prove it in court.

This is the biggest change to the private rented sector in a generation. If you haven't adapted yet, you're exposed. This guide covers exactly what Section 21 was, why it was removed, what replaces it, and the practical steps you need to take to protect your position as a landlord.

What Section 21 was and how it worked

Section 21 of the Housing Act 1988 allowed landlords to end an assured shorthold tenancy without giving a reason. You served a Section 21 notice, gave the tenant at least two months' notice, and if they didn't leave, you applied to the court for a possession order. The court had no discretion. If the notice was valid, possession was granted automatically.

This was known as a “no-fault eviction” because the landlord didn't need to demonstrate any fault on the tenant's part. You didn't need to prove rent arrears, antisocial behaviour, or any other breach. You simply served the notice and waited.

In practice, Section 21 was the most commonly used route for landlords to regain possession. It was simpler, faster, and more predictable than Section 8. Many landlords used it routinely at the end of fixed terms, or when they wanted to sell, renovate, or move back into a property.

Why Section 21 was abolished

The government's position was that no-fault evictions created insecurity for tenants. Tenants could be forced to leave their homes with two months' notice for no reason, making it difficult to plan, raise families, or put down roots. Tenant advocacy groups argued that Section 21 was also used as a retaliatory tool, with landlords serving eviction notices after tenants complained about disrepair or other issues.

The political momentum had been building for years. The Conservative government first committed to abolishing Section 21 in 2019 but never legislated it. The Labour government followed through with the Renters' Rights Act 2025, which received Royal Assent in late 2025 and brought the abolition into force on 1 May 2026.

The same changes ended fixed-term tenancies. Assured shorthold tenancies no longer exist for private lets. New private tenancies are assured periodic tenancies from the start, and existing ones became periodic on 1 May 2026, so tenants can leave with two months' notice at any time. The balance of flexibility has shifted decisively toward tenants.

When Section 21 ended

The abolition of Section 21 took effect on 1 May 2026 for private tenancies in England, including those that existed before the Act. From that date no new Section 21 notice could be served. There was a short transition. A valid notice served on or before 30 April 2026 could still support a court claim, but the claim had to be issued within 6 months of the notice or by 31 July 2026, whichever came first.

That window has now closed. If you served a Section 21 notice but did not issue a claim in time, the notice can no longer be used and you need to start over using Section 8. If you did issue in time, that case carries on under the old rules until it ends. For a full overview of all the changes that came with the Act, read our guide on the Renters' Rights Act and what landlords must do.

What replaces Section 21: the Section 8 system

With Section 21 gone, Section 8 of the Housing Act 1988 is now the only route for landlords to regain possession. Unlike Section 21, Section 8 requires you to prove a specific ground for possession. There are now 37 grounds in total: 26 mandatory grounds (where the court must grant possession if proven) and 11 discretionary grounds (where the court decides whether eviction is reasonable). Many of them can only be used by social landlords or supported housing providers.

The Renters' Rights Act also introduced new grounds to partially compensate for the loss of Section 21. The most important new addition is Ground 1A: intention to sell. This gives landlords a legitimate route to regain possession when they want to sell the property. It needs four months' notice, and the possession date cannot fall within the first 12 months of the tenancy.

Other key grounds include:

• Ground 1: Landlord or a close family member wants to move in (the landlord no longer needs to have lived there before)
• Ground 8: Serious rent arrears (at least three months' rent, or 13 weeks' if paid weekly or fortnightly)
• Ground 10: Some rent unpaid
• Ground 11: Persistent late payment of rent
• Ground 12: Breach of tenancy terms
• Ground 14: Antisocial behaviour

For a detailed breakdown of the grounds and how they work in practice, see our full guide on Section 8 eviction grounds for 2026.

How to evict a tenant under the new system

The eviction process under Section 8 is more demanding than Section 21 ever was. Here is the practical sequence every landlord needs to follow.

Step 1: Identify your ground. You must choose one or more of the Section 8 grounds and have evidence to support each one. Speculative claims weaken your case. Only cite grounds you can prove with documentation.

Step 2: Serve the correct notice. Section 8 notices must use the correct form (Form 3A in England) and specify the correct notice period. Notice periods vary by ground and range from two weeks to four months for most grounds. Getting this wrong invalidates your notice entirely and forces you to restart the process.

Step 3: Apply to the court. If the tenant doesn't leave after the notice period expires, you apply to the county court for a possession order. For mandatory grounds, the court must grant possession if you prove the ground. For discretionary grounds, the court weighs reasonableness and proportionality.

Step 4: Enforcement. If the tenant still doesn't leave after the possession order, you apply for a warrant of possession. County court bailiffs then enforce the eviction. You must never attempt to evict a tenant yourself. Illegal eviction is a criminal offence.

Why compliance records are critical for Section 8 success

This is the point most landlords underestimate. Under the old Section 21 system, missing paperwork such as the How to Rent guide, EPC or gas certificate could invalidate your notice. Those rules went with Section 21. Under Section 8, the compliance rule that decides whether the court can make an order at all is the one on deposits.

Even with a mandatory ground like Ground 8 (serious rent arrears), the court cannot make a possession order if you took a deposit and did not protect it or serve the prescribed information. This applies to every ground except Grounds 7A and 14. The bar lifts once you protect the deposit and serve the prescribed information, even late, or return the deposit. A missing EPC or Gas Safety Certificate does not stop a Section 8 claim, but it still carries penalties.

For discretionary grounds, your conduct matters more. The court considers whether eviction is “reasonable”, and a landlord who hasn't followed the rules is unlikely to be treated sympathetically. Judges look at the full picture, including whether you acted fairly, met your obligations and gave the tenant a proper chance.

So keep dated, timestamped evidence that you have met your compliance requirements throughout the tenancy. It protects you from penalties and helps if a case reaches court. That includes:

• Deposit protection and prescribed information served within 30 days
• Written statement of terms given before a new tenancy is entered into (for written tenancies that began before 1 May 2026, the Renters' Rights Act Information Sheet, due by 31 May 2026)
• Valid EPC provided to the tenant
• Current Gas Safety Certificate provided annually
• EICR completed and provided where required
• Proof of delivery for every document, showing the tenant actually received it

How landlords should adapt to Section 21 being abolished

The abolition of Section 21 requires a fundamental shift in how you manage your tenancies. Here are the practical changes every landlord should make.

Document everything from day one. Record every document you provide, every inspection you carry out and every communication with your tenant, with timestamps and proof of delivery. Under Section 8, contemporaneous evidence is far more persuasive than anything reconstructed after the fact.

Keep the core paperwork up to date. Gaps still carry penalties, and an unprotected deposit stops the court making a possession order on almost every ground. Possession starts with getting these basics right.

Understand the grounds before you need them. Don't wait until you have a problem tenant to learn how Section 8 works. Understand which grounds apply to common situations, such as rent arrears, property damage or wanting to sell, and what evidence each ground requires.

Review your tenancy agreements. Your tenancy terms matter more than ever. Clear, specific obligations in the tenancy agreement make it easier to prove breach under Ground 12. Vague or outdated terms are harder to enforce.

Handle rent increases correctly. With all tenancies now periodic, rent increases must follow the Section 13 process. If you don't follow the correct procedure, the increase is invalid, and any attempt to claim rent arrears based on an invalid increase will fail. For the current rules, see our guide on rent increase rules for landlords in 2026.

What Section 21 abolition means for existing tenancies

The abolition applies to all private tenancies, including existing ones. If you had tenants on fixed-term agreements, those tenancies became assured periodic tenancies on 1 May 2026, even if they were part-way through the fixed term. The fixed term stopped having effect on that date.

This means your existing tenants now have the right to give two months' notice and leave at any time. You cannot hold them to a fixed term. Equally, you cannot end their tenancy without proving a Section 8 ground.

If you were relying on Section 21 as a backstop, planning to serve notice at the end of a fixed term, that option no longer exists. You need to build your compliance and evidence base now, for every current tenancy, so that you have options if problems arise.

Notice periods under the new system

The notice period depends entirely on the ground you use, and getting it wrong invalidates the notice:

• Four months: Ground 1 (landlord occupation), Ground 1A (sale), Ground 2 (mortgage lender), Ground 4A (student HMOs), Ground 6 (redevelopment), Ground 6B (licence refused or revoked).
• Two months: Ground 5 (minister of religion), Ground 5C (end of employment), Ground 7 (death of tenant), Ground 9 (suitable alternative accommodation).
• Four weeks: Ground 8 (serious rent arrears), Ground 10 (some rent unpaid), Ground 11 (persistent late payment).
• Two weeks: Ground 12 (breach of tenancy), Ground 13 (property deterioration), Ground 15 (furniture deterioration), Ground 17 (false statement).
• Immediately: Ground 7A (serious antisocial or criminal behaviour) and Ground 14 (anti-social behaviour). You can start court proceedings as soon as the notice is served.

The 12-month restriction

Two of the most useful grounds, Ground 1 (landlord occupation) and Ground 1A (sale), cannot be used to end a tenancy in its first 12 months. You can serve the notice during the first year, but the possession date in it must fall after the first 12 months. If you grant a tenancy knowing you may want to sell or move in within the year, you are locked in for the full twelve months regardless. Factor this in before the tenancy starts.

Anti-avoidance: using a ground you don't mean

The Act anticipates landlords reaching for whichever ground is convenient. After relying on Ground 1 or Ground 1A, you must not re-let or market the property for 12 months from the date in the notice. Breaking that rule can lead to a council civil penalty of up to £40,000 or prosecution, and the former tenant can apply for a rent repayment order. Misusing a ground, for example claiming you will move in when you don't mean to, carries the same risks. The ground you serve has to be the reason you actually have.

Common mistakes landlords are making post-abolition

Assuming they can't evict at all. Some landlords believe the abolition of Section 21 means they're stuck with problem tenants permanently. In fact, Section 8 provides clear routes to possession, as long as you prove your case and maintain compliance.

Not keeping proof of document delivery. Serving required documents is only half the obligation. You must be able to prove the tenant received them. Email confirmations, signed receipts, and timestamped delivery records are essential.

Using outdated notice forms. The Renters' Rights Act updated prescribed forms. In England, a Section 8 notice now uses Form 3A. If you serve a Section 8 notice using the old Form 3, it may be invalid. Always check you're using the current form.

Neglecting rent records. Ground 8 requires you to prove the tenant owes at least three months' rent (13 weeks' if paid weekly or fortnightly) both when you serve the notice and at the court hearing. Without clear, dated rent records, you cannot meet this threshold. Informal arrangements and cash payments without receipts make this extremely difficult.

Waiting too long to act. Under Section 8, time matters. Rent arrears can fluctuate. Evidence can become stale. If you have grounds for possession, don't delay. Gather your evidence, check your compliance, and serve notice promptly.

Getting your evidence ready for Section 8

Section 21 has been abolished for every private tenancy in England, and there is no sign that it will come back.

Section 8 gives you legitimate routes to regain possession, including new grounds for selling or moving back in. Every one of those routes requires evidence, and almost every one is blocked unless the deposit was protected and the prescribed information served.

The landlords who do well under this system will be the ones who keep their records and compliance in order. Proof of document delivery, timestamped records and organised evidence are what a Section 8 claim relies on.

Start building that evidence now for every property and every tenancy, so the proof is ready if you ever need to use Section 8.
