Key Changes Coming in 2026
Mandatory Licensing Expansion
From October 2026, mandatory HMO licensing will expand to cover all properties with 2 or more tenants from 2 or more households (reduced from 5+ people). This represents the biggest change to HMO regulation in a decade.
Minimum Room Size Requirements
New national minimum room sizes will apply:
- Single rooms: 6.5 sqm minimum
- Double rooms: 11.5 sqm minimum
- All rooms must have natural light and adequate ventilation
Fire Safety Standards
Properties must now include:
- Interlinked smoke alarms on every floor
- CO2 detectors in rooms with fossil fuel appliances
- Approved fire-resistant doors
- Emergency escape routes clearly marked
What Landlords Must Do
- Check if your property needs a license — Use the local council's HMO checker tool
- Apply for a license before the deadline — Processing takes 8-12 weeks
- Update gas and electrical certificates — Ensure compliance with latest regulations
- Review tenant agreements — Update to reflect new requirements
Penalties for Non-Compliance
Unlicensed properties: Unlimited fines and up to £30,000 in penalties
Breach of conditions: Up to £5,000 fines per violation
