Section 8 Form 3A: How to Serve a Notice Seeking Possession in England

Form 3 vs Form 3A: What Changed

Since 1 May 2026, any Section 8 notice for a private assured tenancy in England must use Form 3A, officially titled "Notice seeking possession of a property let on an assured tenancy or an assured agricultural occupancy in the private rented sector." The old Form 3, which many landlords still have saved from previous lettings, is no longer valid for private rented sector tenancies.

This change came through The Assured Tenancies (Private Rented Sector) (Prescribed Forms and Transitional Provisions) (England) Regulations 2026 (S.I. 2026/354). Serving an obsolete Form 3 instead of Form 3A can invalidate the notice.

Form 3 is still used for social housing tenancies. Private landlords must use Form 3A.

How to Complete Form 3A

Form 3A requires you to specify which Schedule 2 ground or grounds you are relying on for possession, along with the factual details and evidence supporting each ground. This is where many landlords make mistakes — the form is not just a tick-box exercise.

For each ground you cite, you must set out the full statutory details:

• Ground 1 (landlord moving in): State that you or a close family member intends to occupy the property as a principal home. Include the name of the person moving in and their relationship to you. You may serve notice during the first 12 months, but it cannot expire before that period ends.
• Ground 1A (selling the property): State that you intend to sell the dwelling-house or a superior interest.
• Ground 8 (serious rent arrears): Specify the exact amount owed and the period it covers. Arrears must equal at least 3 months' rent at both the date of notice and the date of the hearing.
• Ground 14 (nuisance/anti-social behaviour): Detail the specific conduct, dates, and impact.

Incomplete or vague ground descriptions can result in the court refusing to proceed.

Notice Periods by Ground

Each ground has its own minimum notice period. Getting this wrong invalidates the notice.

• Ground 1 or Ground 1A: 4 calendar months
• Ground 4A (student HMO turnover): 4 calendar months
• Ground 8 (serious rent arrears): 4 weeks
• Ground 10 or Ground 11 (minor/persistent arrears): 4 weeks
• Ground 12 (breach of tenancy terms): 2 weeks
• Ground 7A (serious anti-social behaviour): No notice period; proceedings can start immediately, but the court cannot make a possession order until 14 days after notice is given
• Ground 14 (nuisance): Proceedings can start upon service

If you cite multiple grounds with different notice periods, the notice must run for the longest applicable period before you can file with the court.

Serving the Notice

Form 3A must be served in compliance with the statutory requirements and any service provisions in the tenancy agreement. Accepted methods:

• Personal service (handing it directly to the tenant)
• Leaving it at the tenant's last known address
• Registered post

Keep proof of service. A Certificate of Service (Form N215) completed at the time of delivery is the standard approach. If the case reaches court, you will need to demonstrate when and how the notice was served.

Filing at Court

Once the notice period expires without the tenant vacating, you file a possession claim at the County Court using Claim Form N5 and Particulars of Claim N119. Court proceedings must be commenced within 12 months of serving Form 3A — if you miss this window, the notice expires and you need to start again.

Accelerated possession procedure (which previously allowed certain Section 21 claims to proceed without a hearing) has been abolished. Every possession claim now requires a judicial hearing before a District Judge, typically scheduled 8-12 weeks after filing.

Common Mistakes to Avoid

• Using Form 3 instead of Form 3A — automatic invalidation for private rented sector tenancies
• Failing to serve the Information Sheet first — if you did not serve the statutory Information Sheet 2026 on your existing tenant by the deadline, you cannot issue certain possession notices until you do
• Wrong notice period — using two months (the old Section 21 habit) instead of the correct ground-specific period
• Vague ground descriptions — "the tenant has not paid rent" is not enough for Ground 8; you need the exact arrears figure and period
• Setting a Ground 1 or 1A notice expiry date within the first 12 months — the notice can be served during that period, but cannot expire before it ends
