Mould: landlord or tenant responsibility?

Quick answer

Responsibility for mould usually comes down to its cause. Mould from building faults — leaks, rising damp, structural or ventilation defects — is generally the landlord's to fix. Mould from everyday condensation and how the property is used is often the tenant's to manage. When it's disputed, an independent inspection decides.

It comes down to cause

There's rarely a blanket answer to "who pays for mould." In practice it hinges on what's causing it — a building problem or how the home is being lived in. Establishing the cause is what resolves almost every landlord–tenant mould dispute.

If the mould stems from a defect in the building, it's generally down to the landlord to remedy: a roof or plumbing leak, rising damp, penetrating damp, inadequate built-in ventilation, or structural issues. These aren't things a tenant can reasonably fix.

Usually the tenant's to manage

Mould caused purely by everyday living without reasonable ventilation — persistent condensation from never opening windows, drying laundry indoors with no airflow, blocking vents — is often considered the tenant's responsibility to manage through better habits.

The grey area — and how to settle it

Many cases are a mix, which is where disputes arise. The fair resolution is an independent diagnosis. A neutral mould inspection measures the moisture and identifies whether the root cause is structural or behavioural — giving both parties an objective basis rather than an argument. It's used by landlords protecting their property and tenants protecting themselves.

Frequently asked questions

Who is responsible for mould in a rented property?
It depends on the cause. Building faults (leaks, rising damp, ventilation defects) are generally the landlord's; condensation from living habits is often the tenant's to manage.
Does the landlord have to remove mould?
If the mould is caused by a building defect, the landlord is generally responsible for fixing it. If it's from tenant living habits, responsibility shifts.
How is a mould dispute between landlord and tenant resolved?
An independent inspection identifies the root cause — structural or behavioural — giving both sides an objective basis to agree who should act.
Can a tenant be held liable for mould damage?
Potentially, if it results from failing to ventilate reasonably. If it stems from a building fault, the tenant isn't liable. Diagnosis clarifies responsibility.
