HMO planning tips

  1. Mandatory HMO licence: Required for 5+ people from 2+ households. Apply to your local authority — fees typically £500–£1,500 and must be renewed every 5 years.
  2. Article 4 Directions: Many councils restrict new HMOs through Article 4, requiring full planning permission for C3→C4 conversion. Check before buying.
  3. Yield uplift: HMO yields are typically 2–3× higher than standard BTL but require significantly more management and compliance overhead.
  4. Selective licensing: Some areas require ALL private rented properties to be licensed, not just HMOs. Check your local council's licensing register.
  5. Fire safety: Budget for interconnected smoke alarms, fire doors, emergency lighting, and annual fire risk assessments — non-compliance can mean fines up to £30,000.
