Form 3A: the Section 8 notice form explained

Form 3A is the official form a private landlord in England must use to serve a Section 8 notice on an assured tenant from 1 May 2026. Its full title is "Notice seeking possession of a property let on an assured tenancy or an assured agricultural occupancy in the private rented sector". If you use the old Form 3, an out-of-date template or a form that changes the wording, your notice may be invalid.

What is Form 3A?

Form 3A is the prescribed form for a notice under section 8 of the Housing Act 1988 in the private rented sector. It is prescribed by S.I. 2026/354, which came into force on 1 May 2026. The current version is marked (05.26) in the footer, is Crown copyright 2026, and runs to 10 pages.

The regulations work differently from the old forms. They don't print the form in a schedule. Instead, the prescribed form is the version published by the Secretary of State that has effect at the time you serve, "or a form substantially to the like effect". In practice that means:

• the government can replace Form 3A at any time;
• the version that counts is the one in force on the day you serve, not the day you started filling it in;
• you shouldn't change its wording. GOV.UK's forms page says that if you change the wording, the form may not be valid, unless the form itself says you can.

The form applies to England only. Wales uses occupation contracts under the Renting Homes (Wales) Act 2016, and Scotland and Northern Ireland have their own systems.

Where to get the official Form 3A

The official form is on the GOV.UK page Assured tenancy forms, which was last edited on 20 October 2026. The same page links to three companion documents, all uploaded on 24 April 2026:

Document	What it's for
Form 3A: guidance for private landlords	How to complete and serve the notice, with worked date examples
Form 3A: guidance for tenants	What the tenant is told about the notice and their options
Form 3A: legal wording for possession grounds	The full wording of each ground, which you must use in question 4.2

Before you serve, open the GOV.UK page and check that the version code in the footer of the PDF matches the copy you are using. Our Section 8 notice template guide explains how to spot an out-of-date download.

What each part of Form 3A asks for

Form 3A follows the same order every time. Some parts are fixed text; others you must complete.

Part	What it covers	What you do
Cover page	Tells the tenant they don't have to leave straight away, warns against illegal eviction and suggests getting advice	Nothing; fixed text
1.1	Full names of the tenants	Name every tenant, including joint tenants
1.2	Property address	First and second line, town or city, county (optional) and postcode
2.1	The earliest date court proceedings can begin	The day after the longest notice period for your grounds ends
3	The latest date to apply to court	Nothing; fixed text saying 12 months from the date of service
4.1	Tick boxes for common reasons	Optional: Ground 8; Grounds 10/11; Grounds 1/1A; Grounds 4A/5A/5C; Ground 6; Grounds 7A/14; Ground 12; Grounds 13/15; Ground 7B; or Other
4.2	The ground or grounds you rely on	Mandatory. The full legal wording of each ground, not just its name or number
4.3	Your explanation for each ground	Mandatory. A heading per ground and your reasons in your own words, with as much evidence as possible
5.1 to 5.3	Signature, capacity and date	Sign as landlord, agent or licensor; joint landlords each sign or agree that one signs for all
5.4 to 5.7	Name, address, phone and email of the person who signed	Giving an email address means agreeing that the tenant and the court can serve documents on you by email
Page 7	Additional signatures	Up to three more joint landlords or licensors
6	Information for tenants	Nothing; fixed text on advice services, landlord duties and breathing space
Page 10	Extra sheets	Continue any answer here, numbering the question, then sign and date

Why the old Form 3 no longer works for private landlords

Before 1 May 2026, every landlord used Form 3 under S.I. 2015/620. Those regulations are revoked for private assured tenancies from 1 May 2026, except for transitional cases. Form 3 (without the "A") is now for:

• social housing assured tenancies of private registered providers, which stay on the old rules until the reforms are applied to social housing (expected in 2027 at the earliest); and
• private notices served before 1 May 2026, under the transitional rules.

The transitional route has effectively closed. A Section 8 notice served before 1 May 2026 could only be used if the court claim was started by 31 July 2026 (with a narrow breathing-space exception). So for any new private notice today, Form 3 is the wrong form and its use is a defect. The same goes for old Word versions of Form 3 saved before May 2026, which carry the pre-2026 grounds, the old Ground 8 thresholds and old notice-period rules. Our page on tenancies that started before May 2026 explains what happened to those old notices.

What "substantially to the like effect" means

The regulations accept Form 3A "or a form substantially to the like effect". That gives a little room for error, not a licence to redesign the form. Courts ask how a reasonable tenant would understand the notice and whether it gives the same information. An obvious slip that a reasonable tenant would spot and correct may survive, but ground wording that drops key words can make a notice invalid.

There is also a penalty risk. A document that claims to be a Section 8 notice but doesn't comply with section 8 can be treated as a "purported notice of possession", and the council can impose a civil penalty of up to £7,000 for serving one. The safe approach is to reproduce Form 3A's text and structure exactly, including Sections 3 and 6 and the notes, and to copy the GOV.UK legal wording word for word.

Common Form 3A errors

Most problems with Form 3A come from a few places:

• Question 1.1: missing a joint tenant, including one who has moved out.
• Question 2.1: a date that comes too early because of the wrong period, a miscounted month, posting time, or the first-year rule for Grounds 1 and 1A.
• Question 4.2: writing "Ground 8" or "rent arrears" instead of the full legal wording.
• Question 4.3: a one-line explanation with no facts or figures.
• Section 5: a missing signature, or a joint landlord who hasn't signed or agreed to one signing for all.

The full list, with fixes, is in why Section 8 notices fail.
