TL;DR
Section 8 possession grounds are the only route to regain possession from an assured periodic tenancy since Section 21 ended on 1 May 2026. There are 37 grounds in total under Schedule 2 of the Housing Act 1988, but ten of them cover almost every realistic landlord case. Notice periods range from 4 months for selling or moving in, down to 2 weeks for false statements and serious breaches. Mandatory grounds bind the court if proven; discretionary grounds invite the judge to weigh reasonableness. This guide to the section 8 possession grounds covers the ten grounds you actually need, the post-1 May 2026 rules, and the mistakes that get notices struck out.
What Section 8 is — and how it changed on 1 May 2026
Section 8 of the Housing Act 1988 is the fault-based route to ending an assured tenancy. Until 1 May 2026, most landlords used Section 21 — the no-fault route — to recover possession. Section 21 is now abolished for all new tenancies, and pre-existing Section 21 notices expire on 31 July 2026. From August 2026 onwards, the section 8 possession grounds are the only mechanism.
The Renters’ Rights Act 2025 simultaneously expanded the grounds from 17 to 37 under Schedule 2. Some of those 37 are narrow specialists — agricultural workers, ministers of religion, Crown servants. The ten section 8 possession grounds in the next section cover virtually every private landlord scenario in London, including assured periodic tenancies which became the default tenancy type from 1 May 2026.
A Section 8 notice citing one or more of the section 8 possession grounds is formally a Form 3 (Notice Seeking Possession). It must specify the exact ground or grounds being relied on, the date by which the tenant must give up possession, and accurate particulars supporting each ground. Errors that are immaterial may survive judicial scrutiny; substantive errors — wrong ground, wrong date, wrong tenant — get the whole notice struck out and the landlord starts again.
Mandatory grounds vs discretionary grounds
Every one of the section 8 possession grounds is either mandatory or discretionary, and the distinction shapes everything that follows.
Among the section 8 possession grounds, a mandatory ground binds the court. If the landlord proves the facts of the ground, the judge must grant possession. There is no balancing of fairness, no weighing of tenant circumstances. Grounds 1, 1A, 4A, 6, and 8 are the main mandatory grounds for private landlords.
A discretionary ground invites the court to weigh reasonableness. The landlord can prove every fact and still lose if the judge finds it unreasonable in the circumstances — for example, if the tenant has cleared arrears by the hearing date under Ground 10, or if anti-social behaviour was a one-off and provoked. Grounds 10, 11, 12, 14, and 17 are discretionary.
Grounds can be pleaded in the alternative. The most common combination is Grounds 8, 10, and 11 together on arrears cases, so the case proceeds under Grounds 10 and 11 if the mandatory Ground 8 fails because arrears have fallen below the 3-month threshold at the hearing. Pleading multiple grounds increases the chance of success but requires accurate particulars for each.
Within the section 8 possession grounds, mandatory grounds are the landlord’s strongest cards. Discretionary grounds are slower, less predictable, and often resolve through negotiation.
Section 8 possession grounds at a glance
The ten section 8 possession grounds private landlords are most likely to use:
| Ground | Type | Notice | What it covers |
|---|---|---|---|
| 1 | Mandatory | 4 months | Landlord or family member moving into the property |
| 1A | Mandatory | 4 months | Landlord selling the property |
| 4A | Mandatory | 4 months | Student HMO needing vacant possession for the new academic year |
| 6 | Mandatory | 4 months | Substantial redevelopment requiring vacant possession |
| 8 | Mandatory | 4 weeks | Tenant in 3+ months’ rent arrears at both the notice date and the hearing date |
| 10 | Discretionary | 4 weeks | Some arrears (less than 3 months) at the notice date |
| 11 | Discretionary | 4 weeks | Persistent late payment of rent even if not in arrears at the hearing |
| 12 | Discretionary | 2 weeks | Breach of any term of the tenancy other than rent |
| 14 | Discretionary | Immediate | Anti-social behaviour or criminal use of the property |
| 17 | Discretionary | 2 weeks | Tenancy granted on the basis of a false statement |
Across these section 8 possession grounds, the notice period is the minimum the tenant has between receiving the notice and the earliest date the landlord can apply for a possession order. It runs from the date the tenant receives the notice, not the date the landlord posts it — and the landlord must be able to prove service if challenged.
Two grounds carry post-possession rules. Grounds 1 and 1A both have a 12-month protected period: the landlord cannot use the same ground again within 12 months of the previous attempt. Ground 1A also carries a 12-month no-relet rule — re-letting within 12 months after possession is a criminal offence with civil penalties up to £40,000.
Ground 4A has a seasonal window: the notice must expire between 1 June and 30 September, and the ground cannot be used at all if the tenancy was agreed more than 6 months before the tenant’s move-in date.
Grounds 1 and 1A — when the landlord wants the property back
Of the section 8 possession grounds covering owner intent, Ground 1 covers the landlord, their spouse or civil partner, or a close family member moving into the property as their principal home. Ground 1A covers the landlord intending to sell the property — either on the open market or to a specific buyer.
Both are mandatory. Both require 4 months’ notice. Both carry the 12-month protected period, and Ground 1A specifically carries the 12-month no-relet rule. The combination means a landlord using Ground 1A cannot simply repossess and re-let if the sale falls through — they must either complete the sale, leave the property vacant, or sell to a different buyer within the 12-month window. Re-letting inside that window is a criminal offence with civil penalties up to £40,000 per offence enforced by local authorities, plus a potential Rent Repayment Order of up to 2 years’ rent.
The intention must be genuine. Courts have repeatedly thrown out Ground 1 cases where the landlord’s “intention to move in” turned out to be a pretext for raising rent on a new tenant. Evidence helps: estate agent instructions for Ground 1A, mortgage documents for the new property under Ground 1, family member commitments to relocate.
The 12-month protected period dates from the start of the tenancy, not from when the landlord acquires the property — catching buy-to-let purchasers who expected to recover possession immediately after acquisition.
Ground 8 — three months’ rent arrears
Of all the section 8 possession grounds, Ground 8 is the one private landlords use most often. Under the Renters’ Rights Act 2025, two thresholds tightened simultaneously:
- The arrears threshold rose from 2 months to 3+ months at both the notice date and the hearing date
- The notice period doubled from 2 weeks to 4 weeks
Of all the section 8 possession grounds, Ground 8 is the strictest on arithmetic: if the tenant pays rent down below 3 months by the hearing, Ground 8 fails — the court must dismiss it. This is why many Section 8 cases plead Grounds 8, 10, and 11 together: if the mandatory Ground 8 fails because of last-minute payment, the discretionary Grounds 10 and 11 remain in play.
Universal Credit and Housing Benefit complications matter here. Where the tenant’s housing element is paid late or capped, the law requires the court to consider whether the arrears are attributable to benefit payment failures. This doesn’t automatically defeat Ground 8, but it weakens the landlord’s position and can push the judge toward suspending the possession order on terms.
Accurate calculation of arrears at the notice date and the hearing date is non-negotiable. A landlord who serves a Ground 8 notice on arrears of 2 months and 25 days will lose — the threshold is 3 full months at the notice date. A rent ledger, dated bank statements, and a schedule of receipts are mandatory evidence.
Discretionary grounds — behaviour, late payment, and breaches
The discretionary section 8 possession grounds cover the messier reality of difficult tenancies.
Ground 10 captures arrears below 3 months at the notice date. It’s the backup for failed Ground 8 cases and the primary ground when arrears are present but the 3-month threshold isn’t met. Discretionary status means the court can suspend a possession order — common where the tenant agrees to a repayment schedule.
Ground 11 addresses persistent late payment even when the tenant isn’t formally in arrears at any given date. A tenant who consistently pays 2-3 weeks late month after month, then catches up before any single arrears threshold trips, has done nothing to trigger Grounds 8 or 10. Ground 11 exists for exactly this pattern. Evidence is a rent ledger across at least 6-12 months of late payments.
Ground 12 is the catch-all for breach of tenancy terms other than rent. Unauthorised pets, illegal subletting, smoking in a non-smoking property, breach of HMO licence conditions on the tenant’s side. Particulars must specify which term was breached and how.
Ground 14 covers anti-social behaviour and criminal use of the property. It carries no minimum notice period — the landlord can apply to court immediately on serving notice. This is the strongest discretionary ground but requires solid evidence: police involvement, neighbour statements, ASB case papers.
Ground 17 covers tenancies granted on a false statement — typically false employment or income on the original application. The 2-week notice period reflects the seriousness, but discretionary status means the court still weighs proportionality.
The court process after the notice expires
Once one of the section 8 possession grounds has been served and the tenant doesn’t leave by the notice expiry date, the landlord applies to the county court for a possession order. Two procedural routes exist.
The standard possession procedure suits cases with disputes about facts or notice validity. It involves a directions hearing, then a full hearing where evidence is tested. Timeline from application to possession order: typically 3-5 months.
The accelerated possession procedure is available only for some mandatory grounds, only where the case is documentary, and only where the tenant doesn’t defend. It’s faster — typically 4-8 weeks from application to order — but loses its speed advantage if the tenant files a defence.
Court fees for enforcing the section 8 possession grounds are £391 for a paper application and £375 online. Solicitor costs vary but a contested Section 8 hearing typically runs £1,500-£3,500 in legal fees. Costs are recoverable from the tenant in successful mandatory cases, usually not in discretionary ones.
If the court grants possession and the tenant still doesn’t leave, the landlord applies for a warrant of possession and bailiff enforcement. Bailiff backlog in London currently runs 4-8 weeks. Total elapsed time from Section 8 notice service to physical repossession is therefore typically 6-12 months for Ground 8, longer for grounds with 4-month notice periods.
What landlords often get wrong with Section 8 notices
Five recurring errors weaken or destroy what would otherwise be valid section 8 possession grounds applications:
1. Wrong tenant on the notice. Joint tenants must all be named. Adding a tenant’s partner who isn’t on the tenancy doesn’t help; missing a co-tenant is fatal.
2. Inaccurate ground particulars. Each ground requires specific particulars — for Ground 8, the exact arrears amount and dates; for Ground 1, the family member’s name and relationship; for Ground 14, dates and nature of incidents. Generic wording fails.
3. Service date errors. The notice period runs from when the tenant receives the notice, not when the landlord posts it. First-class post is assumed received 2 working days later; the landlord must be able to prove service if challenged.
4. Notice expiring on the wrong day. For monthly tenancies, the notice must expire on the day before a rent period begins — getting the date wrong by even one day invalidates Ground 8 notices in particular.
5. Failure to supply the prescribed Information Sheet. Under the RRA 2025, landlords must provide the Information Sheet by 31 May 2026 or pay a £7,000 penalty. Possession applications by landlords who haven’t complied are vulnerable to being struck out or refused costs.
Across all section 8 possession grounds, a struck-out notice means 4 months for re-service plus another 3-12 months of court process, with no rent recovery throughout. AIIC-accredited inventory clerks producing a check-in report at the start of the tenancy and a check-out report at the end provide the evidential backbone for breach-based grounds — Grounds 12 and 14 cases often fail on evidence alone without them.
FAQ
What are the section 8 possession grounds a landlord can use?
There are 37 grounds in total under Schedule 2 of the Housing Act 1988, but ten cover almost every realistic private landlord case: 1, 1A, 4A, 6, 8, 10, 11, 12, 14, and 17. The grounds split into mandatory (binding on the court if proven) and discretionary (the court weighs reasonableness).
Is Section 21 still available?
No. Section 21 was abolished for all new tenancies from 1 May 2026 under the Renters’ Rights Act 2025. Pre-existing valid Section 21 notices expire on 31 July 2026. From August 2026 onwards, the section 8 possession grounds are the only route to possession.
How much notice does Ground 8 require?
4 weeks — doubled from 2 weeks under the previous regime. The tenant must be in 3+ months’ rent arrears at both the notice date and the hearing date. If arrears fall below 3 months by the hearing, the court must dismiss the ground.
How long does a Section 8 possession case take?
For most section 8 possession grounds, the typical timeline runs 6-12 months from notice service to physical repossession. Ground 8 with 4-week notice can be quicker if undefended; the four-month-notice grounds (1, 1A, 4A, 6) inherently take longer.
What happens if I re-let after using Ground 1A?
Re-letting within 12 months of possession under Ground 1A is a criminal offence. Civil penalties run up to £40,000 per offence enforced by local authorities, plus a potential Rent Repayment Order of up to 2 years’ rent.
Can I use multiple grounds in one Section 8 notice?
Yes — combining multiple section 8 possession grounds is standard practice. Grounds 8, 10, and 11 are commonly pleaded together for arrears cases — if Ground 8 fails on the 3-month threshold, the discretionary grounds remain. Each ground requires its own accurate particulars and supporting evidence.
Do I need a check-in and check-out report for Section 8 cases?
Not formally required by the section 8 possession grounds rules, but for breach-based grounds (12 and 14) a property condition report from an AIIC-accredited inventory clerk is often decisive evidence. Courts give significant weight to independent inventories signed by the tenant at check-in.
