Accelerated possession: what it is and what to do

Accelerated possession is a court process that a private landlord can use to repossess a property using a Section 21 notice, without needing to attend a full court hearing. Because there is no oral hearing in most cases, the process can move quickly, which is why it is important to understand it and to know your options if you receive papers.

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 standard possession claim, the landlord issues proceedings and the case is listed for a hearing where a judge considers the evidence. With accelerated possession, the landlord applies to the court using a paper-only procedure. A district judge reviews the paperwork. If everything appears in order, a possession order can be made without anyone appearing before a judge.

It can only be used where:

• The landlord is relying on a Section 21 notice (not Section 8 grounds)
• There is a written assured shorthold tenancy agreement
• The tenant has not vacated by the date the notice expires

It cannot be used if the landlord also wants to claim rent arrears as part of the same application, a separate money claim is needed for that.

The Section 21 notice must be valid

Accelerated possession stands or falls on the validity of the Section 21 notice. A notice is invalid if:

• It does not give the correct amount of notice (usually two months, though this has changed over time)
• The deposit was not properly protected or the prescribed information was not served
• The landlord did not provide a gas safety certificate, Energy Performance Certificate, or the "How to Rent" guide before the tenancy began
• The property is in a licensing area and does not have the required licence
• An improvement notice or emergency remedial action notice was in force when the notice was served
• The notice was served within the first four months of the tenancy
• The form used was incorrect or the notice was not signed

If the notice is invalid, the court cannot make a possession order on it, even using the accelerated procedure.

What happens after the landlord applies

You will receive court papers through the post. These will include:

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

You have 14 days from the date on the form to respond using Form N11B. Do not ignore the papers.

What to put in your defence

You can defend the claim by challenging the validity of the Section 21 notice. Your defence form should clearly set out the reasons the notice is invalid if any apply to your situation. Common grounds include:

• The deposit was not protected in an approved scheme, or the prescribed information was not served within 30 days of receiving the deposit
• The landlord did not provide the required documents (gas certificate, EPC, How to Rent guide)
• The notice was served while an improvement notice or remedial action notice was in effect, this is a complete bar on using Section 21
• The notice does not give the correct amount of notice
• The property requires a licence and does not have one

If you are in disrepair: this is a highly relevant point. If your landlord has served a Section 21 notice after you complained about disrepair, you may also have a claim for retaliatory eviction, and the existence of a disrepair claim does not prevent you from defending the possession proceedings.

What happens if you do not respond

If you do not return the defence form, the district judge will normally make a possession order without a hearing. You will then have 14 days to leave, after which the landlord can apply for a bailiff's warrant.

What happens if you do respond

If you raise a valid defence, the court will normally list the matter for a short hearing so a judge can consider the arguments. If your defence is upheld and the notice is found to be invalid, the claim will be dismissed, though the landlord may be able to issue a fresh, valid notice.

If Section 21 is abolished

The Renters' Rights Act 2025 abolishes Section 21 notices in England. Accelerated possession as it currently works will therefore cease to apply to new tenancies once the relevant provisions come into force. Check our article on what the abolition of Section 21 means for the latest position.
