What is a Section 8 notice?
A Section 8 notice (formally: Notice seeking possession under Section 8 of the Housing Act 1988) is the legal document a landlord must serve before applying to court for possession of a residential property. It tells the tenant why the landlord wants possession and gives the required notice period before court proceedings can begin.
Section 8 applies to assured tenancies (the standard form used in England since 1989). Most private rented tenancies in England are assured shorthold tenancies — a type of assured tenancy — so Section 8 applies.
Unlike Section 21 (which was abolished by the Renters' Rights Act 2025 and ceased to apply to new tenancies from 1 May 2026), Section 8 requires the landlord to state a reason(a “ground”) for seeking possession. Courts have no obligation to grant possession unless the ground is proved at hearing.
Form 3A: the prescribed form
From 1 May 2026, Section 8 notices for private rented assured tenancies must use Form 3A. The previous form (Form 3, prescribed before the RRA 2025 changes) is no longer valid.
The government states: “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.”
Form 3A is available on GOV.UK (assured-tenancy-forms). LetSense populates Form 3A automatically from your tenancy data, calculates the correct notice period for your selected grounds, and generates a court-ready PDF.

| Ground 8 (Rent arrears — mandatory) | 4 weeks |
| Ground 10 (Rent arrears — some) | 4 weeks |
| Ground 11 (Persistent late payment) | 4 weeks |
| Ground 12 (Breach of tenancy) | 2 weeks |
| Ground 13 (Deterioration of property) | 2 weeks |
| Ground 14 (Nuisance or annoyance) | 0 days |

Mandatory vs discretionary grounds
Mandatory grounds (Ground 8 is the main one) mean the court must grant possession if the ground is proved. If the tenant owes 3 months' rent at both the notice date and the hearing date, the court has no discretion — possession is granted.
Discretionary grounds mean the court decides whether it is “reasonable” to grant possession even if the ground is proved. For discretionary grounds, courts consider whether the breach was serious and whether the tenant can remedy it.
Ground 8: the 3-month arrears threshold
This is the ground most agencies rely on for rent arrears possession. Under the Renters' Rights Act 2025, the threshold increased from 2 months to 3 months (or 13 weeks for weekly rents).
The 3-month threshold must be met at two points:
- At the date the Section 8 notice is served
- At the date of the court hearing
If the tenant pays down arrears between notice and hearing so they owe less than 3 months, Ground 8 fails. You can often fall back on Ground 10 (discretionary, any arrears) or Ground 11 (persistent late payment) if Ground 8 fails, but courts have discretion on those.
How to serve a Section 8 notice
The notice must be served on the tenant personally. Acceptable methods:
- 1.Hand delivery to the property — keep a note of date and time, ideally with a witness.
- 2.First class post — presumed served on the second working day after posting (if not returned). Keep proof of postage.
- 3.Email or other electronic means — valid under the Electronic Communications Act 2000 if the tenancy agreement permits it or the tenant has agreed to receive notices electronically.
- 4.Process server — recommended for contested cases, as they provide a sworn certificate of service.
Important: calculate the notice period correctly
The notice period runs from the date of service, not the date the notice was written. If you post the notice on Monday (first class), it is presumed served on Wednesday. The notice period starts Wednesday. For Ground 8 (4 weeks), proceedings cannot begin until 4 weeks after Wednesday.
12-month limit on court applications
Once you serve a Section 8 notice, court proceedings must be started within 12 months of the notice date. After 12 months, the notice expires and you must serve a fresh one.
Common mistakes that invalidate a notice
- ✕Using Form 3 instead of Form 3A after 1 May 2026
- ✕Serving the notice before arrears reach the 3-month threshold (Ground 8)
- ✕Wrong notice period for the selected grounds
- ✕Notice period calculated from notice date rather than service date
- ✕Serving on the wrong person (must be served on each tenant individually)
- ✕No proof of service — court may dismiss application if service is disputed
- ✕Waiting more than 12 months to issue court proceedings after service
