For landlords who grew accustomed to using Section 21 as a clean exit route, the post-1 May 2026 regime requires a fundamental change in approach. Section 8 demands more evidence, more process, and a clear statutory reason for seeking possession, but it remains fully effective where that reason exists.
The Renters' Rights Act 2025 not only abolished Section 21 but also introduced three new mandatory possession grounds that partially replace its functions. Understanding which ground applies to your situation is the starting point for any possession action from 2026 onwards.
Why Section 21 no longer works
From 1 May 2026, serving a Section 21 notice is not just ineffective, it attracts a civil penalty of up to £7,000. Local authorities actively enforce the ban. Remove any Section 21 templates from your property management workflow immediately.
The only exception is the transitional window for notices served before 1 May 2026: these remain valid if court proceedings are filed by 31 July 2026 (or within 6 months of service, whichever is earlier). After that deadline, the transitional window closes permanently.
The Section 8 possession routes available in 2026
Section 8 allows possession where a specific statutory ground is proved. There are both mandatory grounds (the court must grant possession if the ground is proved) and discretionary grounds (the court weighs all circumstances).
Mandatory grounds, court must grant possession if proved
These are the grounds where, once proved, the court has no discretion. The landlord will obtain possession:
- Ground 1 (Amended), Owner-occupation: Landlord or named family member requires the property as their principal home. 4 months' notice. Requires a prior notice at tenancy start (if not served, this ground may be unavailable).
- Ground 1A (New), Landlord intends to sell: Landlord genuinely intends to sell the property with vacant possession. 4 months' notice. The landlord must not re-let within 3 months of recovering possession.
- Ground 4A (New), Student HMO: For HMOs with full-time students only. Notice can only expire between 1 June and 30 September. 4 months' notice. Partial replacement of Section 21 for student landlords.
- Ground 7A, Serious ASB or criminal conviction: Anti-social behaviour conviction or serious criminal offence related to the property. 1 month's notice.
- Ground 8, Rent arrears (2 months at service and hearing): At least 2 months' rent arrears at both service and the court hearing. 4 weeks' notice. Arrears must still exist on the hearing date.
- Ground 8A (New), Persistent arrears (3 months cumulative): Three months' cumulative rent arrears at any point during the tenancy. 4 weeks' notice. A powerful new ground for landlords dealing with persistent short-payers.
Discretionary grounds, court weighs all circumstances
For discretionary grounds, the court must be satisfied it is reasonable to grant possession, even if the ground is proved:
- Ground 10, Some rent arrears (below Ground 8 threshold): Useful where arrears fall below the 2-month threshold for Ground 8.
- Ground 11, Persistent late payment: Pattern of late payments even where arrears have been cleared. Useful for landlords dealing with habitually late payers.
- Ground 12, Breach of tenancy obligation: Tenant has broken any term of the tenancy agreement. Wide application.
- Ground 13, Deterioration of the property: Tenant has allowed property condition to deteriorate.
- Ground 14, Anti-social behaviour: Nuisance, annoyance, or harassment affecting neighbours. No notice period required, can proceed to court immediately after service.
- Ground 17, False statements at tenancy start: Tenant obtained the tenancy by making a false statement.
How to serve a valid Section 8 notice in 2026
A Section 8 notice served on the wrong form or with an error is invalid, even if the underlying ground is genuine. Follow these steps:
- Step 1, Use Form 3A. The new prescribed form is Form 3A (not the old Form 3). The old form is invalid from 1 May 2026. Use the updated form available in LetSafe UK's Section 8 Notice Pack.
- Step 2, Choose your grounds. You may rely on multiple grounds simultaneously. Use the Section 8 Ground Picker tool to identify all applicable grounds.
- Step 3, Calculate the notice period precisely. Each ground has its own notice period. Calculate from the date of service, not date of writing. Allow for postal service (2 working days for first-class post).
- Step 4, Set out full particulars. For each ground cited, include detailed supporting facts: exact arrears figures, dates of incidents, evidence relied on. Vague particulars can invalidate the notice.
- Step 5, Serve correctly. Personal service (hand to tenant) or first-class post. Keep a certificate of posting or photograph of service.
- Step 6, Wait for the notice period to expire before filing court proceedings. Filing early results in automatic strike-out.
- Step 7, File a possession claim. Complete form N5 (possession claim) and N119 (particulars). Pay the court fee. The hearing date is typically set by the court, expect 4–12 weeks from filing.
Common mistakes with Section 8 notices post-2026
These errors invalidate an otherwise valid possession claim:
- Using old Form 3 instead of Form 3A, invalid from 1 May 2026
- Wrong notice period, especially where grounds have been amended post-RRA
- Arrears figure incorrect or not updated to the date of service for Ground 8
- Failing to serve all named joint tenants, each must receive a separate notice
- No proof of service, undermines the claim if challenged at court
- Filing court proceedings before the notice period has expired, automatic strike-out
How long does Section 8 possession take?
Section 8 claims take longer than the old accelerated Section 21 route. After serving the notice and waiting for the notice period to expire, a court hearing is typically listed 4–12 weeks after filing. For mandatory grounds (Grounds 8, 8A, 7A, 1A), if the ground is proved, the court must grant possession and fix a possession date.
For discretionary grounds, the court has more latitude and timescales are less predictable. Tenants who contest discretionary claims can extend proceedings significantly.
Building a strong evidence file from day one, rent statements, correspondence, inspection records, is essential for an efficient Section 8 process.
Frequently asked questions
Can I still use a Section 21 notice I served before 1 May 2026?+
Yes, but only within the transitional window. A valid Section 21 notice served before 1 May 2026 can still be used to pursue possession if court proceedings are filed by 31 July 2026 (or within 6 months of service, whichever is earlier). After that deadline, the notice is permanently unenforceable and you must proceed via Section 8.
My tenant has left arrears below 2 months, which ground should I use?+
For arrears below the 2-month threshold required for Ground 8, use Ground 10 (some rent arrears, discretionary). You can also add Ground 11 if there is a pattern of persistent late payment. Combining multiple grounds in one notice strengthens the claim.
Can I use Ground 1A to sell my property with a tenant still in place?+
Yes. Ground 1A is a new mandatory ground allowing possession where the landlord genuinely intends to sell the property with vacant possession. Four months' notice is required, and the landlord must not re-let the property within 3 months of recovering possession. The ground is mandatory, if proved, the court must grant possession.
I want my property back for my own use, which ground applies?+
Ground 1 (amended) allows possession where the landlord (or a named family member) requires the property as their principal home. Four months' notice is required. To use this ground, a prior notice must have been served at the start of the original tenancy informing the tenant that this ground may be used. If no prior notice was served, this ground may not be available.
Does the abolition of Section 21 apply to Wales, Scotland, or Northern Ireland?+
No. The Renters' Rights Act 2025 applies to England only. Wales abolished the equivalent (Section 173 no-fault notice under the Renting Homes (Wales) Act 2016) in 2022. Scotland abolished short assured tenancies in 2017. Northern Ireland has different rules. If you let property outside England, the relevant local legislation applies.
