The post-1 May 2026 Section 8 grounds list has 17 mandatory and 7 discretionary grounds, all served on the new Form 3A. Key new/revised grounds: Ground 1A (sale of the property, 4-month notice, 12-month re-let ban), Ground 8 arrears threshold raised to 3 months, Ground 4A (student HMO end-of-academic-year), ASB grounds strengthened. Section 21 is abolished � every English possession claim now runs on Section 8.

For rent-arrears claims the court expects to see escalation letters, an affordability questionnaire and evidence of signposting to advice services. Our Pre-Action Rent Arrears Letters pack (�9) handles this in three escalations.
Picking the right ground
Use as many grounds as reasonably apply, the court will grant possession on any one of them if proved. If you have rent arrears below the three-month threshold, cite Grounds 10, 11 and 12 together. If there is ASB, cite 14 and 14ZA together. Our Section 8 Ground Picker does this automatically.
When to instruct a solicitor anyway
- The tenant has instructed a solicitor and the claim is heading to a contested hearing.
- There is a counter-claim for disrepair, discrimination or harassment.
- There is a vulnerable-adult or child safeguarding dimension.
- The contract value of the tenancy (annual rent � expected remaining term) is materially above the cost of advice.
