Possession Claims Rise as Final Section 21 Deadline Closes In

Landlord possession claims rose by almost 6% in the first three months of 2026, as property owners prepared for the biggest change to the private rental market in decades.

Compared with the previous quarter, the increase amounted to almost 1,300 additional claims. Standard possession claims brought by private landlords rose even more sharply, increasing by 11.1% in just three months.

The timing is significant. The figures cover the final full quarter before Section 21 was abolished for private tenancies on 1 May 2026.

Section 21 had been one of the most widely used routes for recovering possession. The latest English Housing Survey found that, among private renters who had been asked to leave during the previous three years, almost half said they had received a Section 21 notice.

That route has now closed for new notices, but a limited window remains for landlords who served a valid Section 21 notice before 1 May.

Those landlords can still begin possession proceedings, provided they do so by whichever date comes first: the time remaining on the notice or 31 July 2026. Where the earliest date on which proceedings could begin falls on or after 1 August, the notice cannot be used to issue a Section 21 claim.

The important point is that serving notice was only the first stage. The possession claim itself must be issued within the permitted period. A landlord who allows the deadline to pass will need to start again under the new Section 8 framework, which is likely to be a longer and more demanding route, with greater scope for delay and dispute.

Landlords holding an unissued Section 21 notice should therefore review their position promptly. Validity depends on the full history of the tenancy and the landlord’s compliance at the relevant time, rather than simply the date shown on the notice. Leaving the review until the end of July may provide little opportunity to resolve a defect or obtain missing documents before the court deadline expires.

The approaching deadline also comes as councils receive stronger powers to address serious hazards in rented homes.

Since 22 June 2026, local authorities have been able to impose civil penalties of up to £7,000.00 where the statutory conditions are satisfied in relation to a Category 1 hazard. These are the most serious housing hazards and can include severe damp and mould, dangerous electrical installations, fire risks, excessive cold, and structural concerns. The Government estimates that around one in ten privately rented homes contains at least one serious health and safety hazard.

The following day, an updated Housing Health and Safety Rating System came into force. The revised framework reduces the number of hazard descriptions from 29 to 21 and introduces a simplified method of assessing their seriousness. It is the first substantial update to the system in approximately 20 years.

These changes affect both sides of the tenancy. Landlords need to be certain that any possession claim is properly founded and that concerns about the condition of the property have been addressed. Tenants, meanwhile, may need advice where they have received notice, are facing possession proceedings or believe that serious repair issues have been left unresolved.

Our Commercial & Residential Property Litigation team acts for both landlords and tenants. We can advise on possession claims, rent arrears, tenancy compliance, disrepair and enforcement, and provide clear guidance from the first notice through to the conclusion of proceedings.

The rise in possession claims shows how quickly the private rental sector is changing. With the Section 21 transitional deadline approaching and stronger housing enforcement powers now in force, both landlords and tenants should understand their position and obtain advice before matters become more difficult or costly.
