Section 8 Possession Grounds: A Landlord's Guide to the Post-RRA Process

If there is a compliance gap, the deposit must be protected and the prescribed information served first. Only then can Form 3A be given to the tenant. Serving the notice and correcting the gap at the same time does not work.

For the full detail on the 30-day rule and prescribed information requirements, see our guide to deposit protection rules for landlords.

Serving the Section 8 Notice: Form 3A

From 1 May 2026, the notice seeking possession must be served using Form 3A. This is the updated form prescribed under the Renters Rights Act 2025, replacing the previous Form 3. Form 3A is available free from GOV.UK's assured tenancy forms page.

Form 3A requires landlords to:

• State which grounds are being relied on. More than one ground can be included in the same notice.
• Set out the factual basis for each ground.
• Give the correct notice period for each ground claimed.
• Include the landlord's name, contact details, and the property address.

Getting Form 3A wrong has real consequences. An incomplete or inaccurate notice can be dismissed by the court, requiring the landlord to serve a fresh notice and restart the notice period from the beginning.

Notice periods vary by ground. Most grounds require 4 months' notice. Arrears grounds require 4 weeks. Anti-social behaviour grounds have no minimum notice period in advance. The specific notice period is set out under each ground below.

Proof of service matters. Keep a dated record of how and when the notice was delivered: hand delivery, first-class post with a certificate of posting, or email where the tenancy agreement allows for electronic service. Serve the notice at the address where the tenant is currently living, not a correspondence address used when the tenancy was first signed.

Key Mandatory Grounds

Ground 1: Landlord or family member intends to occupy

Notice period: 4 months. Ground: mandatory.

The landlord, their spouse, civil partner, or a specified family member intends to use the property as their only or principal home. This ground cannot be used within the first 12 months of a tenancy. After obtaining possession under Ground 1, the landlord cannot re-let or remarket the property for 12 months from when the notice period expires.

Ground 1A: Landlord intends to sell

Notice period: 4 months. Ground: mandatory.

A new ground introduced by the Renters Rights Act. It applies where the landlord genuinely intends to sell the property. The same restrictions apply as Ground 1: not available in the first 12 months, and a 12-month bar on re-letting or remarketing after possession. Evidence of intent, such as a signed sale agreement or estate agent instruction, will support the claim.

Ground 2: Mortgage lender requires vacant possession

Notice period: 4 months. Ground: mandatory.

Where the property is subject to a mortgage and the lender is exercising its power of sale to recover a debt. The landlord does not need to have notified the tenant at the outset that this ground might be used.

Ground 6: Substantial works or demolition

Notice period: 4 months. Ground: mandatory.

The landlord intends to demolish, reconstruct, or carry out substantial works to the property, and those works cannot reasonably be done while the tenant remains in occupation. The landlord must be able to demonstrate the works are genuine and that the tenant's continued occupation makes them impracticable.

Ground 8: Serious rent arrears

Notice period: 4 weeks. Ground: mandatory.

The threshold for Ground 8 from 1 May 2026 is at least 3 months' unpaid rent, or 13 weeks where rent is paid weekly or fortnightly. The arrears must exist both when the notice is served and on the date of the court hearing. A tenant who clears the full arrears before the hearing defeats Ground 8 entirely.

Ground 8A: Repeated arrears

Notice period: 4 weeks. Ground: mandatory.

This is a new ground targeting habitual non-payers. It applies where the tenant has been at least 2 months in arrears on three or more separate occasions in the preceding three years, regardless of whether those arrears have since been cleared. Unlike Ground 8, a last-minute payment does not defeat this ground.

Key Discretionary Grounds

Ground 10: Some rent arrears

Notice period: 4 weeks. Ground: discretionary.

The tenant is in some arrears but below the Ground 8 threshold. The judge has discretion. Payment history and the context in which arrears built up will both be relevant to whether the court grants possession.

Ground 11: Persistent late payment

Notice period: 4 weeks. Ground: discretionary.

The tenant has persistently paid rent late, even if not currently in arrears. A documented history of late payments, such as bank statements, a rental ledger, or written correspondence chasing overdue rent, strengthens this ground considerably.

Ground 14: Anti-social behaviour

Notice period: None required in advance. Ground: discretionary.

Ground 14 is the only ground where no advance notice period is required before serving Form 3A. However, the court cannot make a possession order until at least 14 days after the notice was served. Evidence is essential: police reports, noise complaint logs, local authority records, and witness statements. The judge will weigh the severity and frequency of the conduct.

Ground 15: Deterioration of furniture or fittings

Notice period: 2 weeks. Ground: discretionary.

Furniture or fittings provided by the landlord have deteriorated due to waste, neglect, or default by the tenant or a member of their household. A photographic check-in inventory showing the original condition of the items, compared against current evidence of deterioration, is needed to support this claim. Landlords seeking possession for deterioration of the property structure or common parts should use Ground 13, which carries the same notice period and discretionary status.

What Happens When You Go to Court

If the tenant does not leave once the notice period expires, the landlord must apply to court.

For a standard possession claim (which can also include a claim for arrears), the forms are N5 (the claim form) and N119 (particulars of claim). The current court fee is £404. Both forms can be submitted online or posted to the county court covering the area where the property is located.

A hearing is scheduled. For mandatory grounds, the landlord must demonstrate the ground is proven. For discretionary grounds, the landlord must also persuade the judge that possession is reasonable.

Current court possession proceedings average more than 8 months from notice to possession order (Ministry of Justice, 2026). The NRLA has described the justice system as heading towards breaking point. Landlords should factor this timeline into their planning.

Common Mistakes That Invalidate Claims

Using the wrong form. The pre-RRA Form 3 is no longer valid for notices served after 1 May 2026. Only Form 3A is accepted for possession proceedings under the new framework.

Wrong notice period. Giving 4 weeks' notice for a ground that requires 4 months is a fatal error. The notice is invalid. A new notice must be served, resetting the clock.

Relying on the wrong ground. The facts of the situation should determine which ground applies. Using a discretionary ground in circumstances where a mandatory one is available weakens the position unnecessarily.

No proof of service. Without a dated record of how the notice was delivered, it is impossible to prove the notice period has expired and court proceedings can be challenged.

Serving at the wrong address. The notice must go to the address where the tenant is living at the time of service. An old correspondence address or the property address if the tenant has temporarily moved out may not be valid.

Unprotected deposit. Most grounds are blocked until deposit protection is confirmed and prescribed information served. The deposit must be protected and prescribed information served before Form 3A is given to the tenant.
