Serving the wrong notice form, using the wrong notice period, or failing to serve correctly are the most common reasons landlord possession claims are struck out by courts. In 2026, the risk is higher than ever, the Renters' Rights Act 2025 introduced new mandatory grounds, new prescribed forms, and removed Section 21 entirely.
This guide explains every legal notice a private landlord in England can serve in 2026, which form to use, and what the consequences are of getting it wrong.
Section 8 possession notice, Form 3A (mandatory from 1 May 2026)
Section 8 of the Housing Act 1988 is now the only statutory possession route in England. The prescribed form is Form 3A, updated for the Renters' Rights Act 2025. Using any earlier version of the form risks invalidity.
- Form required: Form 3A (2026 version), the old Form 3 is invalid
- When to use: Any possession claim for a private rented property in England from 1 May 2026

- Notice periods: Vary by ground, from 2 weeks (Ground 14: anti-social behaviour) to 4 months (Ground 1A: landlord sale)
- Service: Personal service to each named tenant, or first-class post (deemed served 2 working days after posting). Keep a dated proof of postage

Section 13 rent increase notice, Form 4A (mandatory from 1 May 2026)
Section 13 of the Housing Act 1988 is the only lawful rent increase route in England from 1 May 2026. The prescribed form is Form 4A. The old Form 4 has no legal effect from commencement.

Renters' Rights Act Information Sheet 2026, one-off obligation
Every existing tenant in England must be served the Renters' Rights Act Information Sheet 2026 by 31 May 2026. This is not a contractual notice, it is a statutory obligation imposed by the Renters' Rights Act 2025.

- Penalty: Up to £7,000 civil penalty per breach for non-service
'How to Rent' guide, required at new tenancy commencement
Landlords in England must provide the current 'How to Rent' guide to every new tenant at or before the start of the tenancy. This is a pre-condition for serving a valid Section 8 notice, failure to provide it may jeopardise any future possession claim.
- When required: At or before commencement of every new tenancy
- Version: The current version at the date of tenancy commencement, older versions do not comply
- Method: Can be delivered as a PDF by email to the tenant's confirmed email address or in hard copy

When a tenancy deposit is taken, landlords must serve the prescribed information relating to deposit protection. This is a statutory requirement under the Housing Act 2004.
- Deadline: Within 30 days of receiving the deposit
- Scheme: The deposit must be protected in a government-approved scheme (TDS, DPS, or mydeposits) within the same 30-day window
- Content: The prescribed information must include the scheme name and contact details, the amount protected, and the dispute resolution service

Section 21 notice, abolished 1 May 2026
Section 21 of the Housing Act 1988 no longer exists as a possession route in England. Landlords cannot serve a Section 21 notice for any tenancy after 1 May 2026.
- Serving a Section 21 after 1 May 2026: Civil offence, civil penalty of up to £7,000
- Pre-commencement notices: A Section 21 notice served before 1 May 2026 remains valid only if court possession proceedings are filed by 31 July 2026
- Replacement: Section 8 is the only remaining possession route, use Form 3A and cite a statutory ground
Frequently asked questions
What is the correct form for a Section 8 notice in 2026?+
Form 3A, the version updated for the Renters' Rights Act 2025 and mandatory from 1 May 2026. The previous Form 3 is no longer valid. Using the wrong form invalidates the notice even if the underlying ground is legitimate.
What is the correct form for a rent increase notice in 2026?+
Form 4A, updated for the Renters' Rights Act 2025 and mandatory from 1 May 2026. The old Form 4 has no legal effect from commencement. Rent may only be increased once per 12 months with at least 2 months' notice.
Can I still serve a Section 21 notice?+
No. Section 21 was abolished in England on 1 May 2026 by the Renters' Rights Act 2025. Serving a Section 21 notice after commencement is a civil offence with a penalty of up to £7,000. Use Section 8 and Form 3A for all possession claims.
Does the Information Sheet need to be sent to new tenants as well as existing ones?+
Yes. The 31 May 2026 deadline applies to existing tenants. New tenants taking up tenancies after 1 May 2026 must also receive the Information Sheet at or before commencement of their tenancy.
What happens if I serve a Section 8 notice with the wrong notice period?+
The notice is likely invalid. Incorrect notice periods are the most common reason Section 8 notices are challenged and possession claims are struck out. Notice periods vary by ground, from 2 weeks (Ground 14) to 4 months (Ground 1A). Always verify the notice period for each ground you are relying on before serving.
