For social housing teams in England
Awaab’s Law: testing that supports the property record
Respond to damp and mould concerns with a clear investigation, timely action and documented findings.
Use testing where it helps the investigation
Aerolyse can provide agreed sample analysis and written findings to support your wider property investigation.
Testing can help document an identified concern or selected areas after remediation. It is not required in every case, does not itself deliver legal compliance and must not delay action on a known hazard.
The landlord’s duties remain
Aerolyse provides environmental testing and reporting support. We do not determine whether a landlord has met its statutory duties.
