Section 8 grounds explained: notice periods, evidence and timelines
Since the Renters' Rights Act took effect on 1 May 2026, every possession claim in England stands or falls on the grounds you put on your Section 8 notice (Form 3A). Pick the right ground with the right evidence and the process is predictable. Pick the wrong one and you lose months - or commit an offence. This is the reference table we wish every landlord had pinned to the fridge. For the overall process, see our Section 8 notice guide.
Mandatory vs discretionary: the distinction that decides cases
Grounds come in two types. If a mandatory ground is proven, the court must order possession - the judge has no choice. With a discretionary ground, proving the facts is only half the job: the court also decides whether possession is reasonable. In practice, mandatory grounds are what you build a case on; discretionary grounds are what you add as backup.
Every ground landlords actually use, in one table
| Ground | What it covers | Notice period | Type |
|---|---|---|---|
| Ground 8 | Serious rent arrears - at least 3 months' rent unpaid (13 weeks if rent is weekly or fortnightly) at BOTH service and the hearing | 4 weeks | Mandatory |
| Grounds 10 and 11 | Arrears of any amount / persistent late payment | 4 weeks | Discretionary |
| Ground 1 | You or close family (parent, grandparent, sibling, child, grandchild) moving in - not usable in the first 12 months | 4 months | Mandatory |
| Ground 1A | Selling the property - not usable in the first 12 months; 12-month re-letting ban after use | 4 months | Mandatory |
| Ground 6 | Demolition or substantial redevelopment - you must have owned the property before the tenancy started | 4 months | Mandatory |
| Ground 4A | HMO let to full-time students - notice must expire between 1 June and 30 September | 4 months | Mandatory |
| Ground 7 | Tenant has died - proceedings must start within 12 months of the death | 2 months | Mandatory |
| Ground 7A | Severe antisocial or criminal behaviour (conviction, injunction breach) | None - proceedings can start immediately | Mandatory |
| Ground 14 | Nuisance or annoyance to neighbours, or criminal behaviour at the property | None - proceedings can start immediately | Discretionary |
| Ground 12 | Breach of any tenancy term other than rent (unauthorised pets pre-consent, subletting, business use) | 2 weeks | Discretionary |
| Grounds 13 and 15 | Deterioration of the property or furniture through neglect or damage | 2 weeks | Discretionary |
| Ground 7B | Tenant has no right to rent under immigration rules | 2 weeks | Mandatory |
| Ground 17 | Tenancy obtained by a false statement made knowingly or recklessly | 2 weeks | Discretionary |
The evidence courts actually expect
Judges decide on paperwork, not frustration. Match your evidence to your ground family:
- Arrears (8, 10, 11): a dated rent schedule showing every amount due and received, updated to the day of the hearing, plus your reminder letters. Remember the universal credit caveat - arrears that exist only because a UC housing payment has not yet arrived are ignored for Ground 8.
- Moving in or selling (1, 1A): evidence of genuine intention - an estate agent instruction, a memorandum of sale, or a statement explaining the family member's circumstances.
- Breach and damage (12, 13, 15): the signed agreement showing the term breached, dated photographs, inventory comparisons and written warnings.
- Antisocial behaviour (7A, 14): incident logs with dates, neighbour statements, police reference numbers and any conviction or injunction documents.
Realistic timelines by ground
Add the notice period to roughly 2 to 4 months for a court date if the claim is contested, plus several weeks for bailiffs where needed. An arrears case on Ground 8 might resolve in 4 to 6 months end to end; a sale under Ground 1A is closer to 6 to 8 months once the 4 months' notice has run. The single biggest factor in staying at the shorter end is a correctly completed Form 3A with clean compliance paperwork behind it - deposit protected, gas safety, EPC and EICR all served.

Prepare my Section 8 notice →Frequently asked questions
Can I combine grounds on one notice? Yes - citing Grounds 10 and 11 alongside Ground 8 is standard practice in arrears cases, so the claim survives if the tenant pays down below the 3-month threshold before the hearing.
Which grounds are blocked in the first 12 months? Grounds 1 and 1A. Because both carry 4 months' notice, the earliest service date is month 8 of the tenancy, expiring at month 12.
Do discretionary grounds ever succeed alone? Yes, but outcomes vary with the judge and the evidence. Where possible, anchor the claim on a mandatory ground and use discretionary grounds as support.
What if my situation spans several grounds? That is normal - arrears plus damage plus nuisance often travel together. List each ground you can evidence. If you are unsure whether to act at all, a rent review under Section 13 or a renewed written agreement sometimes solves the underlying problem faster than possession.
