Section 21 Abolished: What Replaces It and What UK Landlords Must Do Now

On 1 May 2026, Section 21 of the Housing Act 1988 ceased to have effect in England. The mechanism that allowed landlords to end an assured shorthold tenancy without giving a reason — commonly called a "no-fault eviction" — is gone. If you're a landlord, this is the single biggest change to residential letting law in over thirty years, and it affects every tenancy you manage.

This guide explains what Section 21 was, why it was abolished, what replaces it, and the practical steps you must take now to protect yourself and your rental business.

What Was Section 21?

Section 21 of the Housing Act 1988 gave landlords the right to recover possession of a property let on an assured shorthold tenancy (AST) without needing to prove any fault on the tenant's part. The landlord simply served a notice (Form 6A) giving the tenant at least two months' warning, and if the tenant didn't leave, the landlord could apply to the county court for a possession order. The court had no discretion — if the paperwork was correct, possession had to be granted.

Why landlords relied on it:

• It was procedurally straightforward — no need to prove a specific ground
• It offered certainty — if the form was correct, the court had to grant possession
• It provided an exit route for tenancies that weren't working, without the need to attribute blame
• It was the standard mechanism for ending fixed-term tenancies at their natural expiry date

Why it attracted criticism:

• Tenants could be displaced with no fault on their part
• It was cited as a driver of homelessness, particularly for families with children
• The government's own data indicated that Section 21 notices were the leading cause of homelessness in England
• It created a power imbalance that discouraged tenants from raising legitimate complaints (so-called "retaliatory evictions")

The Timeline: How Abolition Happened

The path to abolition was neither quick nor straightforward.

April 2019: The government first announced its intention to abolish Section 21 evictions.

May 2023: The Renters (Reform) Bill was introduced to Parliament. It included the abolition of Section 21 but stalled before the 2024 general election.

July 2024: The newly elected Labour government committed to bringing forward strengthened legislation.

September 2024: The Renters' Rights Bill was introduced, building on the earlier bill with additional tenant protections.

Late 2025: The Renters' Rights Act 2025 received Royal Assent, with commencement dates set for 2026. For a comprehensive overview of every change in the Act, see our Renters' Rights Act 2025 landlords' guide.

1 May 2026: Section 21 abolished for all tenancies in England, including existing tenancies that predate the Act. Any Section 21 notice served before this date but not yet enforced through a court order is also invalidated. All existing fixed-term ASTs converted to assured periodic tenancy agreements on this date.

This last point is critical. If you served a Section 21 notice in early 2026 and had not yet obtained a possession order by 1 May, that notice is no longer valid. You cannot rely on it.

What Replaces Section 21?

Section 21 has not been replaced by a single equivalent mechanism. Instead, the Renters' Rights Act 2025 expands and strengthens Section 8 of the Housing Act 1988, which requires landlords to cite specific grounds for seeking possession.

The Expanded Section 8 Grounds

Section 8 grounds are divided into mandatory grounds (where the court must grant possession if the ground is proven) and discretionary grounds (where the court decides whether it is reasonable to grant possession). For the full end-to-end process, see our guide to possession via Section 8.

Key mandatory grounds:

• Ground 1 — The landlord previously occupied the property as their only or principal home and wishes to return, or reasonably requires it for occupation
• Ground 1A (new) — The landlord intends to sell the property with vacant possession
• Ground 2 — A mortgage lender requires possession to exercise its power of sale
• Ground 6 — The landlord intends to demolish, reconstruct, or carry out substantial works
• Ground 8 — Serious rent arrears of at least three months (or 13 weeks for a weekly or fortnightly tenancy) at both the date of notice and the date of hearing (see our rent arrears action guide)

Key discretionary grounds:

• Ground 10 — Some rent arrears (below the Ground 8 threshold)
• Ground 11 — Persistent late payment of rent
• Ground 12 — Breach of any term of the tenancy agreement
• Ground 13 — Deterioration of the property or furniture due to the tenant's neglect
• Ground 14 — Nuisance, annoyance, or antisocial behaviour
• Ground 17 — The tenant obtained the tenancy through false statements

New Grounds Introduced by the RRA 2025

The Act introduced two important new grounds to fill the gap left by Section 21:

Ground 1A — Sale of the property. This is entirely new. If you genuinely intend to sell the property with vacant possession, you can seek possession on this ground. However, you cannot use it within the first twelve months of the tenancy, and if you re-let the property within twelve months of gaining possession rather than completing a sale, you face financial penalties.

Strengthened Ground 14 — Antisocial behaviour. The RRA 2025 clarified the definition of antisocial behaviour and introduced faster court processing for the most serious cases, including those involving violence or threats of violence.

Practical Steps Landlords Must Take Now

1. Review Your Tenancy Agreements

If your tenancy agreements still reference Section 21, they need updating. While the clauses don't make the agreement invalid, they are misleading and could cause confusion if a dispute arises. Ensure your agreements reflect the current legal position: all tenancies are now assured periodic tenancies, and possession can only be sought under Section 8.

You do not need to issue new agreements to existing tenants solely because Section 21 has been abolished — the change happens by operation of law. But the next time you update or renew an agreement, ensure it is fully up to date.

Check the rent review clause at the same time. Contractual review clauses no longer operate on an assured periodic tenancy, so every increase now goes through the section 13 procedure — and most Form 4A notices that fail do so on the dates, not the figure.

2. Understand the Section 8 Grounds

This is no longer optional knowledge. Every landlord needs to understand which grounds apply to which situations, the notice periods for each ground, and the evidence courts expect. Our summary of the new eviction rules UK landlords face in 2026 walks through how possession now works end to end. Familiarise yourself with the full list of grounds and the practical requirements for each.

For example, if you may one day want to sell a property with a tenant in it, you need to know about Ground 1A — including the twelve-month restriction and the evidence of genuine intent to sell that courts will require.

3. Start Building Evidence from Day One

Under the old system, evidence was important but not always essential — Section 21 didn't require you to prove anything. That has fundamentally changed. Every Section 8 ground requires evidence, and the quality of your evidence often determines whether you succeed or fail at court.

What good evidence looks like:

• Rent records: A complete, accurate rent ledger showing every payment due and every payment received (or not received). Bank statements corroborating the ledger
• Property condition records: Check-in and check-out reports with dated, time-stamped photographs. Regular inspection reports throughout the tenancy
• Communication records: Copies of all correspondence with the tenant — emails, letters, and text messages. A record of verbal conversations with dates and a summary of what was discussed
• Compliance records: Evidence that you have met all your legal obligations (gas safety, EICR, EPC, deposit protection, How to Rent guide). Failing to comply can undermine your possession claim

4. Conduct Regular Property Inspections

Inspection reports serve two critical purposes: they demonstrate the condition of the property at specific points in time, and they show that you are actively managing the tenancy. If you later need to rely on Ground 13 (property deterioration) or defend against a counterclaim that you failed to maintain the property, inspection reports are your primary evidence — see how to document property condition for court.

Inspections should be conducted at move-in, at regular intervals during the tenancy (every three to six months is standard), and at move-out. Each inspection should include dated photographs, room-by-room condition notes, and ideally acknowledgment from both landlord and tenant. LetSorted can schedule these periodic inspections for you so the interval never slips.

5. Keep Your Compliance Documents Current

Under the Renters' Rights Act 2025, failure to comply with your legal obligations can be used against you in possession proceedings. Ensure the following are always in order:

• Gas Safety Certificate — renewed annually, and renewed on time: it cannot be backdated if you let it lapse
• Energy Performance Certificate (EPC) — valid and meeting minimum energy efficiency standards
• Electrical Installation Condition Report (EICR) — renewed every five years
• How to Rent guide — latest version provided to the tenant
• Deposit protection — deposit protected within 30 days, prescribed information served

6. Act Promptly When Issues Arise

One of the risks of the new system is delay. Under Section 21, a landlord who tolerated months of late payments could simply serve notice and move on. Under Section 8, delay can weaken your case. If a tenant falls into arrears, document it immediately and communicate in writing. If antisocial behaviour is reported, start an incident log straight away. Courts look more favourably on landlords who acted promptly and proportionately.

Promptness cuts both ways on arrears. Ground 8 is measured at two separate moments, and a tenant who pays down the arrears before the hearing takes the mandatory ground away from you — why a Ground 8 rent-arrears notice fails sets out the threshold and the timing. And where the issue reported is damp, mould or a serious hazard, log and act on it: whether Awaab's Law applies to private landlords explains what is actually in force for the sector and what a court will expect of you regardless.

How Existing Tenancies Are Affected

Fixed-Term ASTs

All existing fixed-term assured shorthold tenancies have been converted to assured periodic tenancies by operation of law. This happened automatically on 1 May 2026. Your fixed-term tenancy agreement remains in force — the terms don't disappear — but the tenancy itself is now periodic. The tenant can end it with two months' notice at any time, and you can only seek possession under Section 8.

Rolling Periodic Tenancies

If your tenancy was already periodic (rolling month-to-month after a fixed term expired), very little changes in practical terms. The tenancy continues as it was, but you can no longer serve Section 21 to end it.

Pending Section 21 Notices

If you served a Section 21 notice before 1 May 2026 but did not obtain a court order before that date, the notice is invalid. You cannot proceed with it. If you need possession, you must now use Section 8.

If you obtained a court order based on a Section 21 notice before 1 May 2026, that order remains valid and enforceable. The abolition does not retrospectively invalidate court orders already made.

Common Myths Debunked

"I can never get my property back now"

This is false. The Section 8 grounds provide multiple routes to possession, including new grounds specifically introduced to replace Section 21. If you want to sell the property, move back in, carry out major works, or if the tenant has breached the tenancy, there are grounds available.

"The court process takes years"

A straightforward mandatory ground case typically takes three to six months from notice to possession. That is longer than the old Section 21 accelerated procedure, but it is not the multi-year ordeal some commentators suggest. Complex contested cases can take longer, but they always could.

"Tenants can now stay forever"

Tenants have greater security, but they are not immune from eviction. A tenant who doesn't pay rent, damages the property, causes antisocial behaviour, or breaches the tenancy agreement is at risk of a possession order. And a landlord who genuinely wants to sell or move back in has specific grounds designed for that purpose.

"I need to sell up and leave the market"

Some landlords have exited the market, but many are continuing to operate successfully. The key is to treat letting as a professional activity: keep proper records, maintain the property, comply with the law, and manage tenancies actively rather than passively.

"Section 8 never works — courts always side with the tenant"

On mandatory grounds, the court has no discretion — if the ground is proven, possession must be granted. On discretionary grounds, courts do consider the tenant's circumstances, but they also consider the landlord's. The key factor is evidence. Landlords who present clear, well-organised evidence typically succeed.

"The old Section 21 forms I have saved still work"

No. Any Section 21 notice — whether served, pending, or saved for future use — is now worthless. The legal mechanism no longer exists. Section 8 uses a different form (Form 3A), different notice periods, and an entirely different process.

Frequently Asked Questions

When exactly was Section 21 abolished?

Section 21 was abolished on 1 May 2026 for all tenancies in England, including existing tenancies that predated the Renters' Rights Act 2025. Any Section 21 notice served before that date but not yet enforced through a court order was also invalidated. There was no grace period or transitional arrangement for unexecuted notices.

Can I still evict a tenant without Section 21?

Yes. Section 8 of the Housing Act 1988 provides multiple grounds for possession. Mandatory grounds — where the court must grant possession if proven — include serious rent arrears (Ground 8), landlord wanting to sell (Ground 1A), and landlord wanting to move back in (Ground 1). Discretionary grounds cover situations like antisocial behaviour, persistent late payment, and tenancy breaches.

What if I want to sell my rental property?

Ground 1A, introduced by the RRA 2025, allows you to seek possession if you genuinely intend to sell with vacant possession. You must give four months' notice and cannot use this ground within the first twelve months of the tenancy. If you re-let the property within twelve months of gaining possession instead of completing a sale, you face financial penalties.

How long does the Section 8 eviction process take?

A straightforward mandatory ground case typically takes three to six months from serving notice to obtaining possession. Contested discretionary ground cases can take longer. The key factor is having strong, well-organised evidence prepared from the start of the tenancy. Courts look favourably on landlords who documented everything and acted promptly.

What This Means for Your Business

The abolition of Section 21 is a structural change, not a temporary disruption. It requires landlords to shift from a reactive model (serve notice when you want the property back) to a proactive model (build evidence continuously, manage the tenancy actively, and address problems early).

The landlords who will do well under the new system are those who keep good records, conduct regular inspections, maintain clear communication with tenants, and act promptly when problems arise. None of this is particularly onerous — it's simply good practice that many landlords were already following.

LetSorted is built around exactly this approach. From structured inspection reports with timestamped photos and tenant acknowledgment, to rent tracking that builds a clear payment history, to compliance management that ensures your documents are always in order — every feature is designed to help you build the evidence trail that the new legal framework demands.

If you're not already keeping structured records of your property's condition, your tenant's payment history, and your compliance status, now is the time to start. The cost of not having evidence when you need it is measured in months of delay and thousands of pounds in legal fees. Get started with LetSorted and put your documentation in order before a problem arises.
