How this estimate works
The Housing Ombudsman calculates compensation for damp and mould failures using a percentage of the rent paid during the period of failure. The percentage reflects how much of the property was affected and how severely. The April 2026 Ombudsman Compensation Guidance (effective 1 April 2026) sets out the framework landlords should follow.
- Minor: One room affected, limited impact on daily life — typically 10–25% rent reduction.
- Significant: Multiple rooms or sustained impact on daily life — typically 25–50% rent reduction.
- Severe: Widespread across property, health risk or property made partially uninhabitable — typically 50–75%+ rent reduction.
This tool provides indicative estimates only. Actual compensation depends on the specific circumstances, evidence available, and the Ombudsman's or court's assessment. This is not legal advice.
