Section 21 Deadline Looms for Landlords: Act Now or Risk Losing Your Possession Rights

Landlords who served a Section 21 notice before 1 May 2026 should be aware of a significant deadline that could affect their ability to recover possession of their property.

Following the introduction of the Renters' Rights Act on 1 May 2026, the longstanding "no-fault" eviction procedure under Section 21 of the Housing Act 1988 has been abolished. While landlords can no longer serve new Section 21 notices, transitional provisions preserve the validity of notices that were correctly served before the changes came into force. However, those rights are subject to a strict time limit.

The Critical Deadline: 31 July 2026

For landlords who served a valid Section 21 notice before 1 May 2026, possession proceedings must be issued by the court no later than 31 July 2026 (or six months from service of the notice, if earlier).

This deadline does not simply relate to the claim being submitted. The claim must be formally issued by the court within the permitted period. Given the current pressures on the county courts and administrative delays affecting possession claims, landlords who leave matters until the last minute may find themselves out of time despite having lodged their application.

Does This Affect You?

You may need to take urgent action if all of the following apply:

• You served a Section 21 notice before 1 May 2026;

• The tenant remains in occupation;

• Possession proceedings have not yet been issued;

• The notice has not already expired.

If you meet these criteria, immediate legal advice should be sought to assess whether your position can still be protected.

Section 8 Notices Also Affected

The transitional arrangements also apply to certain Section 8 notices served before 1 May 2026. Landlords relying on grounds such as rent arrears should therefore review their position carefully, as similar deadlines may apply.

‍

What Happens If You Miss the Deadline?

The consequences can be significant.

If possession proceedings are not issued within the required timeframe, the Section 21 notice will cease to have effect and cannot be revived. The landlord will permanently lose the ability to rely upon that notice.

In practice, this means the tenancy will continue under the new assured periodic tenancy regime and any future possession claim will need to be based on one of the statutory grounds available under Section 8.

These grounds include:

• Persistent or substantial rent arrears;

• Anti-social or criminal behaviour;

• Sale of the property;

• Occupation by the landlord or a family member; and

• Other prescribed circumstances.

Each ground has its own evidential requirements, notice periods and procedural hurdles, making the process more complex than the former Section 21 route.

‍

A One-Off Opportunity

The period leading up to 1 May 2026 saw a significant increase in Section 21 notices being served, resulting in a corresponding surge in possession claims. As a result, courts are experiencing considerable backlogs, which further increases the risk of delay.

For landlords who are still considering whether they can rely on a previously served notice, this should be treated as a one-off opportunity rather than a deadline that can be revisited later. Once missed, the Section 21 route is unlikely to be available again.
