Housing Ombudsman’s New Tiered Investigations Process: What London Landlords Must Do Now

The Housing Ombudsman has launched a three-tiered further investigations process in early 2024 to help landlords identify and resolve issues early, aiming to improve complaint handling, repairs, and support for vulnerable residents. London landlords should promptly review and enhance their complaint procedures and service delivery to align with this new framework and avoid escalation.

Housing Ombudsman’s New Tiered Investigations Process: What London Landlords Must Do Now

Understanding the New Further Investigations Process

In early 2024, the Housing Ombudsman introduced a structured, three-tiered further investigations process to encourage landlords to detect and fix problems at the earliest stage. This approach begins with Tier 1, where landlords must submit a response plan addressing identified issues, escalating only if problems persist through Tiers 2 and 3, which involve formal full investigations and published reports.

This development signals a shift towards increased accountability and proactive resolution, with a focus on complaint handling, repairs (notably damp and mould), and vulnerable resident support. Several landlords have already undergone Tier 1 engagement, with ongoing monitoring of their improvement efforts.

Why This Matters to London Landlords

London’s diverse rental market—including single-unit landlords, HMO operators, and large portfolio holders—faces unique operational and compliance challenges. The Ombudsman’s new process means landlords who fail to swiftly identify and resolve service issues risk escalation to public investigations, potentially damaging reputation and incurring regulatory scrutiny.

For landlords managing multiple properties or HMOs, the layered approach requires robust internal controls and timely interventions. Even accidental landlords should note that early responsiveness is now formally expected.

Practical Implications Across Your Operations

  • Complaint Handling: Landlords must review procedures to ensure complaints are logged, investigated, and resolved promptly. Delays or inadequate responses increase risk of Tier 1 engagement.

  • Repairs and Maintenance: Damp and mould remain high-risk areas. Proactive inspections and swift remedial action can reduce complaints escalating to the Ombudsman.

  • Resident Vulnerability: Enhanced awareness and support for vulnerable tenants are critical. Training staff to recognise and respond appropriately forms part of compliance expectations.

  • Data Monitoring: Regular analysis of complaint trends and repair turnaround times helps detect systemic issues early.

  • Communication and Transparency: Clear, timely communication with residents regarding repairs, compensation, or service improvements can prevent dissatisfaction from escalating.

Concrete Next Steps for London Landlords

  1. Review the Housing Ombudsman’s Published Guidance: Access the official further investigations process via the Housing Ombudsman website to understand precise expectations and timelines.

  2. Audit Your Complaint and Repair Handling: Benchmark current performance metrics against Ombudsman priorities. If lacking detailed data, start tracking complaints by type, response times, and outcomes.

  3. Develop or Update Internal Procedures: Establish clear escalation paths and response plans for potential Ombudsman inquiries, ensuring accountability at every stage.

  4. Train Your Team: Implement mandatory training on complaint management, tenant communication, and vulnerability awareness. Smaller landlords may consider external courses or advisory support.

  5. Engage Your Residents: Involve tenants in service improvement plans and maintain transparent communication channels, including about compensation policies where applicable.

  6. Monitor and Document Improvements: Keep detailed records of changes made following Ombudsman interactions or internal reviews to demonstrate measurable service enhancements.

Tailoring Actions to Your Landlord Profile

  • Single-Unit Landlords: Focus on timely communication and quick repairs. Digital tools or letting agents can help streamline complaint handling.

  • HMO Operators: Due to complexity, ensure robust policies for communal areas and rapid response to repair issues affecting multiple residents.

  • Portfolio Landlords: Invest in compliance audits and centralised complaint management systems to detect patterns across properties.

  • Accidental Landlords: Seek advice on regulatory obligations and consider partnering with managing agents to meet new standards.
