How to Serve a Section 8 Notice in 2026 — A Practical Guide for UK Landlords
From 1 May 2026, Section 8 of the Housing Act 1988 becomes the only legal mechanism for private landlords in England to recover possession of a residential property. The Renters' Rights Act 2025, which received Royal Assent on 27 October 2025, abolishes Section 21 no-fault evictions on this date.
This is not a minor procedural change. For the first time in nearly 40 years, every possession claim in the private rented sector must be grounded in a specific legal reason. If you need a tenant to leave — for any reason — you must now follow the Section 8 process.
This guide explains exactly how to do that correctly.
What is a Section 8 notice?
A Section 8 notice is a formal written notice served on a tenant that sets out the grounds on which the landlord is seeking possession. It does not immediately end the tenancy. It triggers a notice period, after which — if the tenant has not left — the landlord can apply to the court for a possession order.
The notice must specify:
- The grounds being relied upon (from Schedule 2 of the Housing Act 1988 as amended)
- The facts supporting each ground
- The date after which possession proceedings will be commenced
- The required information about the tenant's right to seek advice
Serving a Section 8 notice incorrectly — wrong form, wrong notice period, missing information, wrong method of service — will result in the court rejecting the claim. Given that possession proceedings currently take an average of 7 to 9 months from notice to eviction, an invalid notice is an expensive mistake.
The new Form 3A — use this, not Form 3
From 1 May 2026, private landlords in England must use a new form called Form 3A to serve a Section 8 notice. This replaces the previous Form 3 for private tenancies. Form 3 continues to be used by social housing providers only.
Form 3A will be published on GOV.UK before 1 May 2026. Using an outdated form after this date will invalidate your notice.

The mandatory and discretionary grounds explained
Schedule 2 of the Housing Act 1988, as amended by the Renters' Rights Act 2025, contains two types of possession grounds.
Mandatory grounds: if the landlord proves the ground exists, the court must grant a possession order. The judge has no discretion to refuse.
Discretionary grounds: even if the landlord proves the ground exists, the court will only grant possession if it considers it reasonable to do so in all the circumstances.
Most landlords should include both a mandatory and a discretionary ground where possible — for example serving Ground 8 (mandatory, serious arrears) alongside Ground 10 (discretionary, some arrears) and Ground 11 (discretionary, persistent late payment). This provides a fallback if the mandatory threshold is not met at the hearing date.
The key grounds and notice periods from 1 May 2026
Mandatory grounds
| Ground | Reason | Notice Period |
|---|---|---|
| Ground 1 | Landlord or family member wants to move in (requires 12 months' tenancy) | 4 months |
| Ground 1A NEW | Landlord intends to sell (requires 12 months' tenancy; 12-month re-letting ban; £40,000 fine for misuse) | 4 months |
| Ground 1B NEW | Landlord intends to substantially redevelop; 12-month re-letting restriction applies | 4 months |
| Ground 2 | Mortgage lender requires possession (no longer needs to pre-date tenancy) | 2 months |
| Ground 7A | Serious criminal conviction or closure order | Immediate |
| Ground 7B | Tenant has no right to rent in the UK | 2 weeks |
| Ground 8 UPDATED | 3+ months' rent arrears at date of notice AND at hearing (increased from 2 months; UC delays excluded) | 4 weeks |
Discretionary grounds
| Ground | Reason | Notice Period |
|---|---|---|
| Ground 9 | Suitable alternative accommodation available | 2 months |
| Ground 10 UPDATED | Some rent arrears (any amount) at date of notice | 4 weeks |
| Ground 11 UPDATED | Persistent late payment (even if no current arrears) | 4 weeks |
| Ground 12 | Breach of tenancy obligation (other than rent) | 2 weeks |
| Ground 13 | Deterioration of the property through neglect | 2 weeks |
| Ground 14 | Nuisance or antisocial behaviour; illegal use of property | Immediate |
| Ground 15 | Deterioration of furniture due to ill-treatment | 2 weeks |
| Ground 16 | Former employee of the landlord | 2 months |
Ground 8 in detail — serious rent arrears
Ground 8 is the most commonly used mandatory ground and has been substantially changed by the Renters' Rights Act 2025. The new threshold is 3 months' arrears (previously 2 months) for monthly tenancies, or 13 weeks (previously 8 weeks) for weekly tenancies. The arrears must exist both at the date the notice is served AND at the date of the court hearing.
- If the tenant pays down arrears to below 3 months before the hearing, the court cannot grant a mandatory possession order on Ground 8 alone
- Arrears attributable to delayed Universal Credit payments are excluded from the calculation
Grounds 1A and 1B — selling or redeveloping
Both are entirely new mandatory grounds introduced by the Renters' Rights Act 2025:
- If possession is obtained, the landlord cannot re-let the property for 12 months
- Misuse can result in a fine of up to £40,000

Generate a Section 8 Notice →How to serve a Section 8 notice correctly — step by step
Step 1: Choose your grounds and calculate the notice period
Select the grounds that apply to your situation. Where you are relying on multiple grounds with different notice periods, the longest notice period applies to the whole notice.
Step 2: Complete Form 3A
Download Form 3A from GOV.UK once it is published before 1 May 2026. Complete it fully and accurately. For rent arrears grounds, include:
- Monthly rent amount
- Total arrears at the date of serving the notice
- Number of months in arrears
- Date rent was last paid in full
Step 3: Choose your method of service carefully
- Hand delivery: deemed served on the date of delivery. Note on the notice "served by hand on [date]" and keep a copy.
- First-class post: deemed served on the second working day after posting under Section 196 of the Law of Property Act 1925. Weekends and bank holidays do not count. Use recorded delivery and keep the receipt.
- Email: only valid if the tenancy agreement expressly provides for service by email.
Step 4: Wait for the notice period to expire
The tenant does not have to leave when the notice period expires. The notice period simply determines the earliest date on which you can apply to court.
Step 5: Apply to court if the tenant does not leave
If the tenant remains in occupation after the notice period expires, apply to the county court for a possession order:
- Possession Claim Online (PCOL) — available at gov.uk/possession-claim-online, for rent arrears claims (Grounds 8, 10 and 11) only.
- Paper claim (Form N5 and Form N119) — for all other grounds. Court fee: £355.
Step 6: Attend the court hearing
The court will list the case for a hearing, typically 4 to 8 weeks after the claim is issued.
- Mandatory grounds: if you prove the ground, the court must grant a possession order
- Discretionary grounds: the court will decide whether it is reasonable to grant possession
If granted, the court typically orders the tenant to leave within 14 to 28 days. If the tenant does not comply, apply for a warrant of eviction.
The most common mistakes that invalidate a Section 8 notice
- Using Form 3 instead of Form 3A — from 1 May 2026, Form 3 is for social housing only.
- Incorrect notice period — forgetting to use the longest notice period, or miscalculating the service date for postal service.
- Incomplete particulars — failing to set out the full facts supporting each ground. For rent arrears, the court needs a precise arrears figure.
- Arrears below the Ground 8 threshold — serving a Ground 8 notice when arrears are below 3 months. Use Ground 10 or Ground 11 instead.
- Prescribed information failures — failing to have previously served the gas safety certificate, EPC, and How to Rent guide.
- Serving in the first 12 months for Grounds 1 and 1A — both grounds are unavailable in the first 12 months of the tenancy.
What to do if you are in the transitional period (before 1 May 2026)
If you are reading this before 1 May 2026 and need to serve a Section 8 notice now, you must use the current Form 3 and the current notice periods (Ground 8 is currently 2 weeks' notice with a 2-month arrears threshold). The new rules do not apply to notices served before 1 May 2026.
However, any Section 8 notice served before 1 May 2026 can only be used to issue court proceedings up until the date that is 12 months after service, or until a date set by the commencement regulations — whichever comes first.
