Rent arrears are the single most common reason landlords seek possession, but the threshold for a mandatory possession order under Ground 8 moved from 2 months to 3 months under the Renters’ Rights Act 2025. That extra month is a real cash-flow gap, and it means landlords need clean, dated evidence of arrears — not just a spreadsheet — because a court will not grant mandatory possession where the arrears fall below 3 months on the day of the hearing. Grounds 10 and 11 remain available for smaller or persistent arrears but are discretionary, so the judge weighs reasonableness.

Disrepair
A property condition falling below the landlord’s repairing obligations under Section 11 of the Landlord and Tenant Act 1985 or the Homes (Fitness for Human Habitation) Act 2018. Tenants can sue for damages and specific performance. Disrepair is not in itself a defence to a possession claim, but a damages counterclaim can be set off against rent arrears — which can drop the arrears below the Ground 8 threshold — and it weighs against the landlord on the reasonableness test for discretionary grounds.
Form 3A (Notice of Seeking Possession, Section 8)
The prescribed form a private landlord uses to start a Section 8 possession claim under the Housing Act 1988. GOV.UK publishes two versions: Form 3A for the private rented sector and Form 3 for social housing, so a private landlord who serves Form 3 has used the wrong form. It identifies the tenancy, the grounds being relied on (from Schedule 2 to the Housing Act 1988) and the date by which the tenant must give up possession. Notice periods vary by ground: no minimum notice for grounds 7A and 14 (anti-social behaviour), 4 weeks for ground 8 (rent arrears), 4 months for ground 1A (landlord sale) post-RRA 2025. A defective notice — wrong form, wrong ground, wrong notice period, missing prescribed wording — is the most common reason possession claims fail at first hearing.
Ground 8 (Serious Rent Arrears)
The mandatory possession ground for serious rent arrears under Schedule 2 of the Housing Act 1988. Since the Renters’ Rights Act 2025 the threshold is at least three months’ rent unpaid (13 weeks’ for weekly tenancies), up from two months, and the Section 8 notice period is four weeks. The arrears must be at or above the threshold both when the notice is served and again at the hearing, so a tenant who pays below it before the hearing defeats the ground.
Mandatory Ground
A ground for possession under Schedule 2 of the Housing Act 1988 that the court must grant if proved. Examples include Ground 1 (landlord moving in), Ground 1A (sale) and Ground 8 (serious arrears). Contrast discretionary grounds, where the court decides if possession is reasonable.
Notice Period
The minimum period a landlord must give before seeking possession under Section 8. Most grounds now require 4 months' notice under the Renters Rights Act 2025, anti-social behaviour can be served with immediate effect, and Ground 8 arrears notice is 4 weeks.
Possession Order
The court order made at the end of a possession claim, requiring the tenant to give up the property to the landlord on a specified date. Two main types under Section 8: outright (give up by a fixed date, typically 14–42 days) or suspended (postponed if the tenant complies with terms, e.g. clearing arrears). If the tenant does not leave by the date in the order the landlord must apply for a Warrant of Possession to enforce eviction by a county court bailiff or High Court Enforcement Officer.
