Quick Answer

The Renters' Rights Act 2025 replaced the old Section 8 notice (Form 3) with the new prescribed Form 3A from 1 May 2026, and rewrote the notice periods at the same time. The period varies sharply by ground: four weeks for rent arrears and most discretionary breaches, four months for owner-occupation grounds (1, 1A, 1B, 6 and 6A), two weeks for the new domestic-abuse perpetrator ground (14A), no minimum notice period for the anti-social-behaviour-with-conviction Ground 7A (the court cannot make a possession order within 14 days of notice), and no minimum at all for Ground 14. Get the notice period wrong and the Form 3A is voidable on its face. The court will dismiss the claim and the landlord pays the wasted court fee plus, often, the tenant's costs.

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.

Section 21 has gone. Every possession claim now runs through Section 8 on the new Form 3A, and that means the Section 8 notice period — which used to be a curiosity for the small number of Section 8 cases — is now the gating 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 full Act is at legislation.gov.uk. The new Form 3A is prescribed by SI 2026/354.

A wrong notice period kills the notice. Mountain v Hastings (1993) 25 HLR 427 is the foundational Court of Appeal authority on the consequences of getting prescribed-information requirements wrong, and although it predates the 2026 regime, the strict-compliance logic survives.

The Periods, Side by Side

The four-month grounds are the headline change. Before the Renters' Rights Act these would all have been Section 21 cases with two months' notice. The four-month period is part of the policy quid pro quo for abolishing the no-fault route — tenants get longer to find somewhere else, and the landlord cannot use the "ground" as a fig leaf for a routine recovery.

---

The Four-Month Family — Grounds 1, 1A, 1B, 6 and 6A

These are the grounds where the landlord wants the property back for a settled non-arrears reason: own occupation, family-member occupation, sale, demolition, or compliance with enforcement action.

Four months is a substantial commitment. A landlord serving Form 3A on Ground 1A in May 2026 cannot expect proceedings to issue before mid-September. With listing pressures running at 8 to 16 weeks in most regions, the realistic possession date is March 2027 — nearly a year after deciding to recover.

This has changed the economics of buy-to-let. Several landlord trade bodies have argued that the new periods amount to a soft rent freeze on any tenancy that the landlord might want to exit. Whether or not that is right, the period is the law and there is no judicial scope to abridge it. The court has no power to dispense with the notice requirement on these grounds.

Practical implications:

• The four-month period starts from the date of service, not the date the notice is drafted. Reliable service methods — recorded delivery, service by a process server, or attended service with photographic evidence — are the practitioner norm.
• The burden of proving service rests on the landlord. Vague witness statements about "posting it through the door" rarely survive cross-examination, on the case-law line. Stronger evidence is the published practitioner standard.
• The published timing position is that the period runs strictly from the date of service; courts have not abridged it on the case law to date.

For Grounds 1, 1A and 1B the four-month period is paired with a twelve-month re-letting lockout. See our Ground 1A intent-to-sell re-letting lockout guide for the consequences of re-letting too early.

The Four-Week Family — Grounds 8, 10, 11, 12 and 13

This is the working set for arrears claims and routine tenancy breaches.

Four weeks is the period from the date of service of Form 3A to the earliest date the landlord can issue proceedings. The clock starts on the day after service.

Two arithmetical traps that catch landlords:

1. Four WEEKS is twenty-eight days. It is not "a month." A Form 3A served on 1 May 2026 entitles the landlord to issue on 29 May 2026 at the earliest. Issuing on 28 May 2026 kills the claim.

2. The arrears must subsist on the date of issue, not just on the date of notice. For Ground 8, a tenant who pays down to below the three-month threshold during the four-week notice period defeats the mandatory ground absolutely. 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) on BOTH the date of the notice and the date of the hearing. See our Ground 8 13-weeks rule guide.

The Fourteen-Day Ground — 7A

Ground 7A is the mandatory anti-social-behaviour ground. The conditions are strict: a relevant conviction, a breach of an injunction made under the Anti-social Behaviour, Crime and Policing Act 2014, a closure notice on the property, or a finding that the tenant has been convicted of an offence in connection with antisocial behaviour. The conditions are listed at Section 84A of the Housing Act 1985 and incorporated into the assured tenancy regime by reference.

Fourteen days' notice. The shorter period reflects the seriousness of the underlying conduct and the public-protection element. Even so, fourteen days is fourteen days. Issuing on day 13 voids the notice.

Where the conduct is so serious that fourteen days is too long, a landlord may apply to the court for an injunction under Part 1 of the 2014 Act, which can be obtained without notice in cases of real urgency.

The Two-Week Ground — 14A

New for 2026. Inserted by the Renters' Rights Act 2025. Where one joint tenant is the victim of domestic abuse from another joint tenant or a household member, the landlord can recover possession against the perpetrator on Ground 14A.

Two weeks is the notice period. The ground is mandatory if the conditions in the new Schedule 2 paragraph are met — primarily that the conduct of the perpetrator amounts to domestic abuse within the meaning of Section 1 of the Domestic Abuse Act 2021, and that the victim-tenant supports the application.

The ground sits alongside the new Section 8A regime, under which the victim-tenant can apply directly to the court for a transfer of the tenancy with the perpetrator removed. The Domestic Abuse Commissioner's office has issued guidance for landlords and managing agents on engaging with Ground 14A — the guidance is at the Domestic Abuse Commissioner's website (retrieved 14 May 2026).

The No-Minimum Ground — 14

Ground 14 is the discretionary anti-social-behaviour ground. There is no statutory notice period. The Form 3A can specify any period — including same-day — and proceedings can issue immediately.

In practice, "no minimum" is rarely used in practice. The court will be slow to grant possession on the day of service of a notice, and even on Ground 14 a court can extend time for the tenant to respond. CPR Part 55.6 allows the court to abridge or extend time as it sees fit.

The most common use of Ground 14 is same-day issue paired with an application for an interim 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 at the normal listing pace.

How to Calculate the Notice Period Correctly

The notice period runs from the day after service. Section 8(4AA) of the Housing Act 1988 uses the words "is to be specified in the notice and is not to be earlier than" — meaning the date in the notice is the earliest date the landlord can issue.

Worked example: Form 3A on Ground 8 served on 1 May 2026.

• Day of service: 1 May 2026 (does not count)
• Day 1: 2 May 2026
• Day 28: 29 May 2026
• Earliest issue date: 29 May 2026

If the notice specified an earlier date — say 26 May 2026 — and the landlord issued on that date, the notice is voidable. The defence is in the tenant's hands.

Worked example for Ground 1A served on 1 May 2026:

• Four months from 1 May = 1 September 2026
• Earliest issue date: 2 September 2026 (Section 8(4AA) reads "is not to be earlier than", so the period must have elapsed)

Where the four-month period ends on a weekend or bank holiday, the issue date is the next working day. This is not in the statute but is the working assumption of every County Court office.

Service and Proof of Service

Form 3A must be served on the tenant. Section 196 of the Law of Property Act 1925 sets out the deemed-service mechanism for written notices generally: a notice served by post is deemed served at the time at which the letter would in the ordinary course be delivered, unless returned undelivered.

In practice, landlords should:

1. Serve in person where possible, with two witnesses or photographic evidence.
2. Send by first-class post with proof of posting from the Post Office.
3. Email a scanned copy in addition, if the tenancy agreement contemplates email service. Most modern tenancy agreements now do.
4. File a witness statement of service at the same time as issuing proceedings, 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 leading modern authority on deemed service of written notices under Section 196 LPA 1925 is Kinch v Bullard [1999] 1 WLR 423.

The Form 3A Itself — What Must Be in It

SI 2026/354 prescribes the form. The required information:

• Landlord's full name and address for service
• Tenant's full name and address
• Property address
• Tenancy start date and tenancy type
• The Schedule 2 ground or grounds being relied on
• The facts giving rise to the ground (Ground 8: arrears figure and statement period; Ground 1: identity of the family member if relevant)
• The earliest date on which proceedings may be issued
• Statement that the notice expires twelve months after the earliest issue date

A Form 3A that omits any prescribed item is voidable. Several early County Court judgments in May 2026 have struck out claims where the notice omitted the twelve-month expiry statement — a small omission with a fatal consequence.

The MHCLG model Form 3A is available on gov.uk (retrieved 14 May 2026). It carries the SI reference and the prescribed schedule, and is updated when the underlying statutory instrument changes.

What Tenants Can Do With a Bad Notice

A tenant who suspects the notice is bad has three options:

1. Wait and defend. If the landlord issues, the tenant raises the defective notice as a defence at the first hearing. If the court agrees, the claim is dismissed and the landlord starts again with a fresh notice.

2. 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 crystallises the position without waiting for the landlord to issue. Cost-effective only where the dispute is ongoing.

3. Seek free advice. The Housing Loss Prevention Advice Service is free to any tenant served a Section 8 notice (regardless of income or means), funded under the Legal Aid Sentencing and Punishment of Offenders Act 2012 as amended. The service operates from County Courts and via the legal-aid telephone gateway. Citizens Advice and Shelter England give related advice without the HLPAS court connection.

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 to the court early. Tenants who can take advice should.
