England Section 21 deadline: old notices face final court cut-off on 31 July

Landlords in England who served a Section 21 notice before the rental reforms took effect face a final transitional deadline this week. Court proceedings relying on the old notice must be started by 31 July 2026, or by the notice’s own earlier expiry date.

The deadline does not revive an invalid or expired notice, and it does not mean every pre-May notice remains usable until Friday. The government’s guidance says landlords can use a Section 21 notice served before 1 May 2026 to begin proceedings only up to and including whichever comes first: the time left on the notice or 31 July 2026.

What changed in England

The tenancy reforms in the Renters’ Rights Act 2025 began on 1 May 2026. From that date, Section 21 was removed for existing and new assured tenancies in England. A limited transition allowed some notices served before commencement to continue towards a court claim.

That transition is now reaching its outer limit. Official guidance, last updated on 13 July, states that possession proceedings based on a pre-commencement Section 21 notice cannot be started after 31 July 2026. If the earliest date for proceedings shown in the notice falls on or after 1 August, the guidance says the notice is invalid for issuing proceedings.

This is an England-only change. Landlords elsewhere in the UK should use the possession rules and official guidance for Wales, Scotland or Northern Ireland rather than applying the English deadline to their tenancy.

The deadline may be earlier

The important phrase is “whichever date comes first”. A notice may already have expired, or its own time limit may run out before 31 July. The final national date is therefore not an automatic extension.

Norwich City Council has also reminded landlords that the relevant possession claim must be issued by the court by the deadline. Merely preparing papers, contacting a solicitor or sending documents does not itself satisfy that requirement.

Validity remains a separate question. The government guidance lists conditions that affected Section 21 notices, including the type of tenancy, the notice period, tenancy-deposit protection, prohibited payments and certain property documents. Property condition enforcement action can also affect whether a notice is usable. A looming deadline does not cure an earlier defect.

Pre-May Section 8 notices are also affected

The transitional rules also matter where a landlord served a Section 8 notice before 1 May using the former grounds and form. Government guidance says proceedings based on such a notice can begin only up to whichever comes first: 12 months after the notice was given or the three-month period beginning on 1 May 2026.

There are specific provisions where a tenant is in a debt-respite breathing space, so landlords should not assume that every case follows an identical timetable. The correct date depends on the notice, ground and circumstances.

Practical checks before 31 July

Landlords or managing agents holding an old notice should identify which route it uses, record when it was served, check its stated dates and confirm whether a claim has actually been issued. They should also gather the tenancy and compliance records relevant to the notice rather than relying on the deadline alone.

Where there is doubt about validity, expiry or court procedure, the safest next step is prompt independent legal advice. This article is general information, not legal advice. Starting a possession claim has serious consequences for both landlord and tenant, and the correct process depends on the individual tenancy.

What happens after the deadline

After the applicable transitional date, a landlord cannot use the old Section 21 notice to start proceedings. If possession is still sought, the case may need to begin under the post-1 May Section 8 framework using an available statutory ground and the current process.

The deadline is therefore a final administrative checkpoint, not a general instruction to bring a claim. Landlords should first establish whether possession is still required, whether the old notice remains valid and whether the legal and procedural conditions are met.
