Open full guideWhy Mandatory Ground matters for landlords
Mandatory grounds give the best possession certainty because the court must grant the order if the ground is proved. But each has its own evidence bar and notice period — Ground 1A (sale) requires genuine intention to sell, and a landlord who re-lets within 12 months of a Ground 1A possession can be sued. Picking the right ground is the single most important decision in a post-RRA Section 8 claim.

Arrears (Rent Arrears)
Unpaid rent that is past its due date. Ground 8 of Schedule 2 to the Housing Act 1988 (mandatory) requires at least 3 months of rent arrears under the Renters Rights Act 2025 (previously 2 months). Grounds 10 and 11 remain as discretionary grounds.
HMO (House in Multiple Occupation)
A property let to 3 or more people from 2 or more households who share facilities (kitchen, bathroom, toilet). Any HMO with 5 or more occupants from 2 or more households needs a mandatory HMO licence from the local authority. Many councils also operate additional licensing for smaller HMOs.
Landlord Licensing
Local authority schemes that require landlords to hold a licence to let property in a defined area. Three types: mandatory HMO licensing (national), additional licensing (smaller HMOs), and selective licensing (non-HMOs). Operating without a required licence carries fines up to £30,000 and can invalidate possession claims.
Property Redress Scheme
A government-approved ombudsman scheme for property-related complaints. Letting agents in England must be members of a redress scheme (The Property Ombudsman or Property Redress Scheme). The Renters Rights Act 2025 extends mandatory redress to private landlords.
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.
Section 8 Notice
A possession notice served under Section 8 of the Housing Act 1988 citing a specific ground. From 1 May 2026 this is the only route to possession in England. Common grounds: Ground 1 (landlord moving in), Ground 1A (sale), Ground 8 (3 months' arrears).
