Mould Law for Landlords 2025: What You Need to Know (And How to Stay Compliant)

🚨 What Is the New Mould Law for Landlords?
Following the tragic death of toddler Awaab Ishak and a growing crisis in rental housing conditions, the government has introduced stricter mould and damp legislation for landlords starting October 2025.
- Under the Mould Law for Landlords 2025, you are now legally required to:
- Respond to tenant reports of mould or damp within 14 days
- Investigate and document the cause of mould, not just clean it
- Begin necessary repairs within 7 to 21 days, depending on severity
- Provide tenants with written findings and a clear action plan
- Maintain rental properties in a condition free from significant mould risks

⚠️ What Happens If You Don’t Comply?
Landlords who ignore the new law face serious consequences:
💸 Fines and rent repayment orders
🧾 Enforcement notices from local authorities
❌ Being added to the rogue landlord database
👎 Reputational damage and tenant legal action
This law applies to all landlords, including private lets, HMOs, and letting agents acting on behalf of landlords.
