Section 21 Abolished: What Landlords Need to Do Now

1. What “abolition” actually means

Section 21 of the Housing Act 1988 allowed landlords of assured shorthold tenancies to recover possession without giving a reason, provided procedural requirements (deposit protection, EPC, gas safety, How to Rent guide) had been met. From 1 May 2026, that route disappears. All possession claims against assured tenants must be brought under a reformed Section 8, which requires the landlord to establish a specific ground for possession on the evidence.

The effect is twofold. First, every tenancy becomes, in practice, open-ended: the tenant chooses when to leave (on two months’ notice), and the landlord can only end the tenancy for a reason recognised by statute. Second, possession proceedings become merits-based rather than procedural, meaning every case will go to a hearing rather than through the accelerated paper-based route that Section 21 made available.

2. The key dates

30 April 2026. The last day on which a valid Section 21 notice can be served. After 4:30pm on this date, no further Section 21 notices can be issued, regardless of the tenancy’s start date.

1 May 2026. Section 21 is abolished. All existing assured shorthold tenancies automatically convert to assured periodic tenancies. Fixed-term clauses cease to have effect.

31 May 2026. Deadline for landlords of existing tenancies to provide tenants with the government-produced Renters’ Rights Act Information Sheet 2026. The penalty for non-compliance is up to £7,000.

31 July 2026. The long-stop deadline for issuing court proceedings on the basis of any Section 21 notice served before 1 May 2026. After this date, any unissued Section 21 claim is time-barred and the notice cannot be relied upon.

3. Transitional rules for notices already served

A Section 21 notice served before 1 May 2026 remains valid after that date, but with a compressed window for court action. The landlord must issue possession proceedings by the earlier of:

This matters in practice because it can shorten the window a landlord would otherwise have had. For example, a Section 21 notice served on 25 April 2026 would, under the pre-existing rules, give the landlord until 24 October 2026 to issue proceedings. Under the transitional rules, the deadline is the earlier of that date or 31 July 2026, which means 31 July 2026 is the effective hard stop. Landlords sitting on Section 21 notices served in the run-up to 1 May should diarise 31 July 2026 carefully.

Also worth noting: if the earliest date for possession proceedings specified in the Section 21 notice falls on or after 1 August 2026, the notice is invalid for the purposes of issuing proceedings at all.

• six months from the date the notice was served, or
• 31 July 2026.

4. What replaces Section 21

From 1 May 2026, all possession against assured tenants proceeds under Section 8 of the Housing Act 1988, as substantially amended by the Renters’ Rights Act 2025. There are 37 grounds for possession in the revised Schedule 2 to the Housing Act 1988, some mandatory (where the court must grant possession if the ground is established) and some discretionary (where the court also considers whether possession is reasonable).

The grounds most likely to be relevant to a typical private landlord include:

• Ground 1: landlord or close family member intends to occupy (four months’ notice; cannot be used in the first 12 months)
• Ground 1A: landlord intends to sell (four months’ notice; cannot be used in the first 12 months; 12-month re-let restriction)
• Ground 6: demolition or substantial redevelopment (four months’ notice)
• Ground 8: at least three months’ (or 13 weeks’) rent arrears at the date of notice and hearing (four weeks’ notice)
• Grounds 10 and 11: some rent arrears, or persistent late payment (four weeks’ notice; discretionary)
• Ground 12: breach of a significant term of the tenancy (two weeks’ notice; discretionary)
• Ground 14: anti-social behaviour (immediate; discretionary)

5. What landlords should do before 1 May 2026

Portfolio review. Identify any tenancies where possession is likely to be needed in the near term. If Section 21 is a realistic option and the prerequisites (deposit protection, EPC, gas safety, How to Rent guide) are in order, serving before the deadline preserves the faster route for at least some of the transitional period.

Compliance audit. A Section 21 notice is only valid if the underlying compliance is in order. The same is true for most Section 8 grounds from May 2026 onwards: a court will not grant possession where the deposit is unprotected or prescribed information has not been served. There is limited time now to remedy long-standing compliance gaps.

Tenancy documentation. Any tenancy agreement template in current use needs to be rewritten for the post-Section 21 regime. Fixed terms, contractual rent reviews, blanket pet bans and penalty clauses for early tenant departure are all void under the new Act.

Rent review strategy. Contractual rent reviews are abolished. From 1 May 2026, rent increases must follow the Section 13 statutory procedure (two months’ written notice, no more than once in any 12 months). Landlords should plan their first post-commencement rent review with this in mind.

6. What landlords should do after 1 May 2026

Issue the Information Sheet. All existing assured tenants must be given the government-produced Renters’ Rights Act Information Sheet 2026 by 31 May 2026. This is a mandatory step and carries a civil penalty for non-compliance.

Move to the new tenancy template. Any new tenancy granted on or after 1 May 2026 must be in the form of an assured periodic tenancy and must include (or be accompanied by) the written statement of terms.

Keep better records. Without Section 21 as a fallback, breach-based possession under Section 8 will turn on evidence: warnings issued, communications with the tenant, rent ledgers, inspection reports. A landlord who relies on memory and informal communications will be in a much weaker position in court than one who maintains clear written records.

Plan for longer possession timelines. Every Section 8 claim requires a court hearing, and the county court possession lists are already under pressure. Landlords should budget for longer timescales and factor this into rent arrears tolerance, insurance arrangements and void provisions.

7. The bigger picture

The abolition of Section 21 is the headline reform, but it sits within a wider package: the new PRS Database (from late 2026), the Private Landlord Ombudsman (expected 2028), the Decent Homes Standard for the PRS and the extension of Awaab’s Law. Landlords who treat 1 May 2026 as a single compliance hurdle will find themselves repeatedly catching up. The more useful framing is that the private rented sector is moving from a lightly regulated contractual model to something closer to the regulated professional service standard that has always applied in social housing.
