For landlords, mould is a repair and compliance issue as well as a cleaning job. Damp and mould growth is one of the hazards assessed under the Housing Health and Safety Rating System in England, and councils can take enforcement action where it is serious. Social landlords in England are already bound by Awaab's Law timescales, and the government has legislated to extend similar duties to private rented homes. A slow or superficial response to a tenant's report is the most common way a manageable problem turns into a dispute.

Mould treatment for rented property focuses on speed and a clear record. Affected rooms are cleaned and treated, finishes made good where needed, and the visit is documented with before and after photos, the areas treated, moisture readings and a plain explanation of the likely cause. Where the cause is a building fault, such as a failed extractor fan, a leaking gutter or missing insulation, that is stated clearly so it can be repaired, and where it is condensation, practical advice for the occupants is included without simply blaming them.

What is included

Landlord and end-of-tenancy mould treatment: FAQs

How quickly should a landlord deal with a mould report?

As soon as reasonably possible. Social landlords in England must investigate significant damp and mould within 10 working days under Awaab's Law, and emergency hazards within 24 hours. Private landlords should already act promptly under their repairing and fitness duties, and the government has legislated to bring them under Awaab's Law, with timing set separately. A fast inspection and clear record protects both tenant and landlord.

Can a landlord charge a tenant for mould?

Only in limited cases. End-of-tenancy dispute services generally expect the landlord to show the mould resulted from the tenant's behaviour rather than the property, for example a working extractor fan and heating that the tenant did not use. Where the cause is a building issue such as poor ventilation, cold walls or a leak, the cost falls to the landlord. Good records of inspections and advice given matter a lot in any dispute.

What records should a landlord keep about mould?

Keep the date of each report, inspection notes, photos before and after work, moisture readings, a description of the cause, details of the work done and any repairs arranged, and copies of advice given to the tenant. These records show the problem was taken seriously and help if the council, a redress scheme or a tenancy dispute service becomes involved.

Is mould treatment enough to meet a landlord's duties?

Not on its own. Cleaning removes the hazard for now, but the landlord is also expected to deal with the cause where it relates to the property, such as repairing leaks, fixing or upgrading extractor fans, providing adequate heating or improving insulation. Treatment plus a clear plan for the cause is what shows the problem has actually been addressed.
