Accelerated possession: what it is and what to do

Accelerated possession is a court process built on Section 21 notices. The Renters' Rights Act 2025 abolished Section 21 on 1 May 2026. So no new accelerated claim can start. But older claims, started on pre-abolition notices, still move through the courts. Papers can still arrive. Here is how the process works for those cases, and your options.

Key facts

• Ministry of Justice figures show landlords made 22,733 possession claims in the county courts of England and Wales in January to March 2026, with 6,888 repossessions carried out by county court bailiffs. Mortgage and landlord possession statistics, GOV.UK
• In the same quarter there were 16,848 possession orders and 10,172 warrants, each down on the same period a year earlier. Mortgage and landlord possession statistics, GOV.UK

What is accelerated possession?

In a normal possession claim, the landlord starts a court case. A judge then weighs the evidence at a hearing. Accelerated possession ran differently. The landlord applied on papers only. A district judge read them. Papers in order meant an order could follow. Nobody stood before a judge.

It could only be used where:

• The landlord relied on a Section 21 notice, not Section 8 grounds
• A written tenancy agreement existed
• The tenant had not left by the notice's expiry

It could not carry a rent arrears claim in the same application. That needed a separate money claim.

The Section 21 notice must be valid

The process works only where the underlying notice was valid. A notice fails where:

• The notice period fell short. Usually two months was needed, though the rules changed over time
• The deposit was never properly protected. Or the prescribed information never came
• The gas certificate, energy certificate, or How to Rent guide never came before the tenancy began
• The home sat in a licensing area with no licence
• An improvement notice, or emergency works notice, ran at service
• The notice came in the tenancy's first four months
• The wrong form was used, or the notice went unsigned

An invalid notice supports no possession order. That holds even in the accelerated procedure. And since abolition, no invalid pre-2026 notice can be served again. The landlord would need a Section 8 ground instead.

What happens after the landlord applies

Court papers arrive in the post:

• Form N5B, the landlord's possession claim
• A defence form, Form N11B

You hold 14 days from the date on the form to reply, using Form N11B. Never ignore the papers.

What to put in your defence

You can defend the claim by showing the notice was invalid. On the defence form, set out the reasons that fit your case. Common ones:

• The deposit sat outside an approved scheme, or the prescribed information never came within 30 days
• The required papers never came: gas certificate, EPC, How to Rent guide
• The notice came while an improvement or remedial notice ran. That barred Section 21 completely
• The notice period fell short
• The home needed a licence and had none

In disrepair? That matters a lot. A notice served after a disrepair complaint may mean a revenge-eviction argument too. And a disrepair claim stops none of your defence to the possession case.

What happens if you do not respond

No defence form back means the district judge usually makes a possession order with no hearing. Fourteen days to leave follow. After that, the landlord can seek a bailiff's warrant.

What happens if you do respond

A valid defence raised usually brings a short hearing. A judge weighs the arguments. A winning defence, with the notice found invalid, sinks the claim. And since abolition, no fresh Section 21 notice can follow. The landlord would need a Section 8 ground.

Section 21 is abolished: what remains

The Renters' Rights Act 2025 abolished Section 21 in England on 1 May 2026. No new accelerated claim can start. The process now matters only for older claims, started on pre-abolition notices, still moving through the courts. Check our article on what the abolition of Section 21 means for the full position.
