Form 3A Notice Periods Explained: 4 Months, 4 Weeks, 2 Weeks — and the Grounds With No Minimum
How long must a private landlord in England wait between serving Form 3A and starting a possession claim? The notice periods under section 8(4AA) of the Housing Act 1988 for the common grounds, how to count them, and how to serve the notice.
Quick Answer
For private assured tenancies in England, Form 3A replaced the old Section 8 notice (Form 3) from 1 May 2026, and the notice periods changed at the same time. The minimum period between service and the earliest date a claim can begin is fixed by section 8(4AA) of the Housing Act 1988 and depends on the ground: four months for the landlord or family moving in (Ground 1), selling (Ground 1A) and redevelopment (Ground 6); four weeks for the rent-arrears Grounds 8, 10 and 11; and two weeks for Grounds 12 and 13. For the anti-social behaviour Grounds 7A and 14 there is no minimum: the date in the notice may be the date of service (s.8(4)), but an order on those grounds alone cannot take effect within 14 days of service (s.7(5D)). A notice that gives too little notice for the ground relied on puts the claim at risk, and the landlord may have to start again with a fresh notice. This article covers England. From 1 May 2026 these rules apply to private assured tenancies. Assured tenancies of social housing let by private registered providers (housing associations) stay on the pre-1 May 2026 rules, including Form 3, the two-month or eight-week Ground 8 threshold and section 21, until the Renters' Rights Act changes are commenced for them; GOV.UK says this will be 2027 at the earliest. In Wales most tenancies are occupation contracts under the Renting Homes (Wales) Act 2016.

Why Notice Periods Are Doing More Work Than Ever
Before 1 May 2026, a landlord with an assured shorthold tenancy had two routes to possession. Section 8 was used for the cases where a stated ground was easy to evidence — usually rent arrears or anti-social behaviour. Section 21, the "no-fault" route, was used for everything else.
For private assured tenancies, section 21 has gone. Every possession claim on a private tenancy now runs through Section 8 on Form 3A, and that means the Section 8 notice period is now the key step on every recovery.
The notice period is set by Section 8(4AA) of the Housing Act 1988, as amended by the Renters' Rights Act 2025. The Act is at legislation.gov.uk/ukpga/2025/26. Form 3A is prescribed by SI 2026/354.
A defective notice can defeat the claim. Mountain v Hastings (1993) 25 HLR 427 is the foundational Court of Appeal authority on the content of a Section 8 notice (confirmed in Prempeh v Lakhany [2020] EWCA Civ 1422).
The Periods, Side by Side
| Notice period | Grounds | Mandatory or discretionary? |
|---|---|---|
| 4 months | 1 (landlord or close family moving in), 1A (landlord selling), 6 (redevelopment) | Mandatory. Grounds 1 and 1A are available only if the tenancy began at least a year before the date specified in the notice (Ground 1A has an exception where notice of compulsory acquisition has been given) |
| 4 weeks | 8, 10, 11 | 8 mandatory; 10 and 11 discretionary |
| 2 weeks | 12, 13 | Discretionary — breach of a tenancy term, deterioration |
| 4 months | 6B | Mandatory — compliance with enforcement action |
| No minimum (the date in the notice may be the date of service; an order on 7A or 14 alone cannot take effect within 14 days of service) | 7A | Mandatory — serious anti-social behaviour with a conviction or equivalent |
| No minimum (as for 7A) | 14 | Discretionary — anti-social behaviour |
Where a notice relies on more than one ground, the longest period applies (section 8(4AA)), unless the notice includes Ground 7A or 14, in which case proceedings can begin immediately (section 8(4)).
The four-month grounds are the headline change. Before the Renters' Rights Act many of these would have been Section 21 cases with two months' notice.
The Four-Month Grounds — 1, 1A and 6
These are the grounds where the landlord wants the property back for a settled non-arrears reason: own occupation, family-member occupation, sale or redevelopment.
Four months is a substantial commitment. Ministry of Justice statistics for April to June 2026 show a median of 27.1 weeks from claim to landlord repossession.
Practical implications:
- The four-month period runs from service, not from the date the notice is drafted. Reliable service methods — recorded delivery, service by a process server, or attended service with photographic evidence — are the practical norm.
- The burden of proving service rests on the landlord.
For Grounds 1 and 1A there is also a restriction on re-letting. Where a landlord relies on Ground 1 or 1A, the landlord must not let the property (on a tenancy of 21 years or less, or a paid licence) or market it for letting, from the day the notice is served until the end of 12 months beginning with the earliest date given in the notice, whether or not the tenancy continues.
The Four-Week Grounds — 8, 10 and 11
This is the working set for arrears claims.
Grounds 8, 10 and 11 need four weeks beginning with the date of service before proceedings may begin (Housing Act 1988 s.8(4AA)).
Two points that catch landlords:
-
Four WEEKS is twenty-eight days. It is not "a month."
-
The arrears must still meet the threshold at the hearing. For Ground 8, a tenant who pays down to below the three-month threshold before the hearing defeats the mandatory ground. The discretionary Grounds 10 and 11 can survive, but the mandatory route is gone.
For Ground 8, the threshold is three months' arrears (or 13 weeks for weekly/fortnightly tenancies) both when the notice is served and at the hearing. See our Ground 8 13-weeks rule guide.
The Two-Week Grounds — 12 and 13
Ground 12 (breach of another term of the tenancy) and Ground 13 (deterioration of the property) are discretionary. The minimum notice is two weeks.
Ground 7A — No Minimum Notice
Ground 7A is the mandatory anti-social-behaviour ground. Its conditions are set out in Ground 7A of Schedule 2 to the Housing Act 1988. The notice must be served within 12 months of the conviction or court finding relied on, or within 3 months of a closure order (with the period running from any appeal's determination) (s.8(4C)–(4F)).
There is no minimum notice period: the date in the notice may be the date of service (s.8(4)), but an order on Ground 7A or Ground 14 alone cannot take effect within 14 days of service (s.7(5D)).
Where the conduct is urgent, a landlord may apply to the court for an injunction under Part 1 of the Anti-social Behaviour, Crime and Policing Act 2014, which can be obtained without notice in cases of real urgency.
Ground 14 — No Minimum Notice
Ground 14 is the discretionary anti-social-behaviour ground. There is no minimum notice period: the date in the notice may be the date of service (s.8(4)), but an order on Ground 7A or Ground 14 alone cannot take effect within 14 days of service (s.7(5D)).
Ground 14 can be paired with an application for an injunction under Part 1 of the Anti-social Behaviour, Crime and Policing Act 2014. Where the underlying conduct is genuinely urgent, the injunction restrains the conduct while the possession claim proceeds.
How to Calculate the Notice Period Correctly
Section 8(4AA) of the Housing Act 1988 sets the minimum period between service of the notice and the earliest date given in it for proceedings to begin. For Grounds 8, 10 and 11 that is four weeks beginning with the date of service.
Worked example: Form 3A on Ground 8 served on 1 May 2026. The four weeks beginning with 1 May 2026 end on 28 May 2026.
Worked example for Ground 1A served on 1 May 2026: four months from 1 May 2026 ends 31 August 2026.
If the notice gives an earlier date than the minimum period allows, the claim may fail on that notice.
Service and Proof of Service
Form 3A must be served on the tenant. Section 196 of the Law of Property Act 1925 applies to service of the notice only where the tenancy agreement incorporates it. Where it does, a notice is sufficiently served if it is left at the tenant's last-known place of abode, or sent by registered post or recorded delivery and not returned undelivered; a notice sent that way is deemed served when it would in the ordinary course be delivered (LPA 1925 s.196(3)–(4); Recorded Delivery Service Act 1962 s.1).
In practice, landlords should:
- Serve in person where possible, with a witness or photographic evidence.
- Send by first-class post with proof of posting from the Post Office.
- Email a copy in addition, if the tenancy agreement provides for email service.
- Keep a witness statement of service ready for issue, exhibiting the proof of posting and the notice.
The court will not assume service. Disputes about service are common and the landlord bears the burden of proof on the balance of probabilities.
The Form 3A Itself
SI 2026/354 prescribes Form 3A. Use the form published on the GOV.UK assured tenancy forms page, and copy the ground wording from GOV.UK's "Form 3A: Legal wording for possession grounds". GOV.UK's instruction is: "Do not change the wording of these forms unless the form says you can. If you change the wording, the form may not be valid."
What Tenants Can Do With a Defective Notice
A tenant who thinks the notice is defective has three options:
-
Wait and defend. If the landlord issues, the tenant raises the defective notice in the defence and at the first hearing. If the court agrees, the claim on that notice fails unless the court considers it just and equitable to dispense with the notice, which it cannot do for Grounds 7A, 7B or 8 (Housing Act 1988 s.8(1)(b) and (5)); the landlord may then have to serve a fresh notice.
-
Apply for a declaration. Less common, but available — the tenant can apply for a declaration under CPR Part 8 that the notice is invalid. This settles the position without waiting for the landlord to issue. Cost-effective only where the dispute is ongoing.
-
Get advice. The Housing Loss Prevention Advice Service, funded by the Legal Aid Agency, gives free early legal advice to anyone at risk of losing their home from the moment they receive written notice, and on-the-day advice and representation at possession hearings, whatever their income. Find a provider at find-legal-advice.justice.gov.uk. Citizens Advice and Shelter England also advise.
The single most common tenant response to a defective notice is to do nothing and then raise it as a defence. This works, but it loses the tenant the chance to put their position early. Tenants who can take advice should.
Looking Ahead: Landlord Registration
Registration on the Private Rented Sector Database is not yet a legal requirement. Once it is in force, an unregistered landlord will still be able to serve Form 3A, but the court will be unable to make a possession order on most grounds while the breach continues. See PRS Database for landlords: what registration means for your possession claim.
Serving is the easy part. A notice period counted correctly still leads nowhere if the deposit or, in time, the registration position is wrong. ComplyWithMe's guide to Section 8 grounds for possession after the Renters' Rights Act 2025 sets out those bars alongside the grounds, and its exposure check shows what a property is exposed to from a postcode and a few answers.
