From 1 May 2026, every Section 8 possession notice served in England must use the new prescribed Form 3A. The old Form 3 is abolished. If you serve a notice on the wrong form after commencement, the court will strike it out and you will have to start again — losing months. This guide explains exactly what Form 3A is, why it replaced Form 3, how to complete it, and what to watch out for.
What is Form 3A and why it replaced Form 3
Form 3A is the prescribed notice form for Section 8 possession proceedings under the Housing Act 1988 as amended by the Renters' Rights Act 2025. It replaces Form 3 (which was the prescribed form under the Assured Tenancies and Agricultural Occupancies (Forms) (England) Regulations 2015). The change was necessary because the Renters' Rights Act 2025 restructured the possession grounds, introduced new grounds (1A, 1B, 6A, 14A), amended notice periods, and converted all tenancies to periodic Assured Tenancies. Form 3 simply did not accommodate these changes.
What changed between Form 3 and Form 3A
| Feature | Old Form 3 | New Form 3A |
|---|---|---|
| Tenancy type reference | Assured Shorthold Tenancy / Assured Tenancy | Assured Periodic Tenancy only (ASTs no longer exist) |
| Grounds listed | Original Housing Act 1988 grounds | Full post-RRA 2025 grounds including 1A, 1B, 6A, 14A |
| Notice periods | Pre-2026 periods (e.g. Ground 1 = 2 months) | Updated periods (e.g. Ground 1 = 4 months, Ground 1A = 4 months) |
| Tenant information section | Basic rights summary | Expanded tenant rights information reflecting RRA 2025 protections |
| Ground 8 arrears threshold | Two months' rent | Three months' rent at both service and hearing |
| Section 21 cross-reference | Present | Removed entirely (Section 21 abolished) |
When to use Form 3A
Form 3A must be used for every Section 8 possession notice served on or after 1 May 2026, regardless of when the tenancy started. This applies to:
- New tenancies granted after 1 May 2026 (which are periodic Assured Tenancies from day one)
- Existing ASTs that auto-converted to periodic Assured Tenancies on 1 May 2026
- Existing periodic tenancies that were already running before commencement
- HMO per-room tenancies, where each occupier's tenancy is assured
There is no grace period for switching forms. From 1 May 2026 it is Form 3A or nothing. If you have pre-printed Form 3 stock, destroy it.
How to complete Form 3A step by step
- Landlord details. Enter the full legal name and correspondence address of every person who is a landlord under the tenancy. If a company, use the registered name and registered office.
- Tenant details. Enter the full name of every person named as tenant. All named tenants must be served.
- Property address. Enter the full address of the dwelling, including postcode. This must match the address in the tenancy agreement.
- Grounds relied upon. Tick every ground you intend to rely on. You may cite multiple grounds. For each ground ticked, you must provide full particulars in the next section.
- Particulars of each ground. For each ground, write a clear factual statement explaining why the ground is made out. For rent arrears (Ground 8 or 10), include the exact sum outstanding, the date arrears began, and the payment history. For anti-social behaviour (Ground 14), include dates, descriptions and any police reference numbers.
- Notice period. The form will state the earliest date on which proceedings can begin. This is calculated from the date of service plus the notice period for the longest-notice ground cited. Do not set a date earlier than the statutory minimum.
- Date and signature. Sign and date the form. If you are an agent, confirm your authority to act and provide the agent's details.
- Service. Serve the completed form on every named tenant. Keep a dated copy and proof of service (hand delivery with witness, or recorded delivery).
Common mistakes to avoid
- Using the old Form 3. Any notice served on Form 3 after 1 May 2026 is invalid. The court will not accept it.
- Insufficient particulars. Ticking a ground but providing only a one-line summary is a frequent reason for notices to be challenged. Give full facts — dates, amounts, references.
- Wrong notice period. Each ground has its own minimum notice period. If you cite multiple grounds, the notice period is the longest of all cited grounds. Getting this wrong invalidates the notice.
- Not serving all tenants. Every person named on the tenancy must be individually served with a copy of the notice.
- Omitting the landlord's address. The notice must include a valid correspondence address for the landlord. A PO Box alone may not suffice if the tenant needs to serve counter-notices.
- Serving too early. Ground 1A (landlord intends to sell) and Ground 1 (landlord or family occupation) require the tenancy to have been in existence for at least 12 months before service.

What happens if you use the old Form 3 after 1 May 2026
A Section 8 notice served on the old Form 3 on or after 1 May 2026 is not a valid notice under the Housing Act 1988 (as amended). The tenant or their solicitor will apply to have it struck out, and the court will agree. You will then need to re-serve on Form 3A and wait the full notice period again before issuing proceedings. In a rent-arrears case, this delay could mean the tenant clears just enough arrears to fall below the Ground 8 threshold — costing you a mandatory ground.
Using the wrong form after commencement is one of the most expensive landlord mistakes. The cost of re-serving, re-waiting, and potentially losing a mandatory ground far exceeds the cost of getting the right form from day one.

Frequently asked questions
Can I still use Form 3 if the tenancy started before 1 May 2026?
No. The relevant date is when the notice is served, not when the tenancy started. Any Section 8 notice served on or after 1 May 2026 must use Form 3A, regardless of the tenancy commencement date.
Do I need to use Form 3A in Wales, Scotland or Northern Ireland?
No. Form 3A is prescribed for England only. Wales uses notices under the Renting Homes (Wales) Act 2016. Scotland uses Notices to Leave under the Private Housing (Tenancies) (Scotland) Act 2016. Northern Ireland uses Notices to Quit under the Private Tenancies Act (NI) 2022.
What if I served a valid Form 3 before 1 May 2026 but haven't issued proceedings yet?
A Form 3 served before 1 May 2026 remains valid provided it was properly served while the pre-commencement regime applied and you issue proceedings within the notice validity window. You do not need to re-serve on Form 3A. However, if the notice expires and you need to re-serve, the new notice must use Form 3A.
Can I download Form 3A from GOV.UK?
The government publishes the prescribed form in the statutory instrument. However, the bare statutory form does not include ground-by-ground guidance, a notice-period calculator, or a proof-of-service log. The LetSafe UK Section 8 Notice Pack includes all of these plus pre-filled versions for every ground.
Is there a fee to serve a Section 8 notice on Form 3A?
There is no court fee to serve the notice itself. Court fees apply only when you issue possession proceedings (currently £355 for an accelerated possession claim and £355 for a standard claim). The notice is simply a document you serve on the tenant directly.
What if the tenant refuses to accept service of Form 3A?
If the tenant refuses personal service, you can use recorded delivery to the property address, or leave it at the property. Keep a witness statement or proof of posting. The court will accept service by first-class post under the Civil Procedure Rules if you can evidence despatch.
