Mould growth in rental properties is a common issue that can cause problems for both tenants and landlords.

In the UK, landlords have legal responsibilities to ensure their properties are safe and habitable, which includes addressing mould problems promptly. In this article, we'll delve into the landlord's responsibility concerning mould in rental properties in the UK, as well as the obligations of tenants, and provide guidance on how to handle mould-related issues effectively.

Landlord Responsibilities:


Providing a Safe Environment: Landlords are legally obligated to provide tenants with a safe and habitable living environment. This includes ensuring that the property is free from hazards such as mould that could affect the health and well-being of occupants.

Maintaining the Property: Landlords are responsible for maintaining the property in good repair and ensuring it is fit for habitation. This includes addressing any issues that could contribute to mould growth, such as leaks, dampness, and poor ventilation.

Taking Action on Mould: If mould is present in a rental property, landlords have a duty to take prompt and appropriate action to address the problem. This may involve cleaning and removing mould, repairing any underlying issues causing moisture buildup, and preventing mould from recurring.

Providing Information and Advice: Landlords should inform tenants about the risks associated with mould and provide guidance on how to prevent its growth. This may include advising tenants on proper ventilation, moisture control measures, and how to report mould-related issues.

Tenant Responsibilities:

Maintaining Cleanliness: Tenants have a responsibility to maintain cleanliness in their rental property to prevent mould growth. This includes regular cleaning of surfaces, proper disposal of food waste, and minimizing clutter that can trap moisture.

Reporting Issues: Tenants should promptly report any signs of mould or moisture problems to their landlord. Early detection allows landlords to address mould issues before they worsen and become more difficult to remediate.

Ventilation: Tenants should ensure adequate ventilation in their rental property by using extractor fans in bathrooms and kitchens, opening windows when possible, and avoiding blocking air vents.

Laws Applicable:

Landlord and Tenant Act 1985: This legislation outlines the landlord's obligation to keep the structure and exterior of the property in repair, including addressing issues such as dampness and mould that could affect habitability.

Housing Health and Safety Rating System (HHSRS): Under the HHSRS, local authorities have powers to take enforcement action against landlords whose properties fail to meet certain health and safety standards, including those related to mould and dampness.

Environmental Protection Act 1990: This legislation provides powers to local authorities to address environmental health issues, including mould and dampness in rental properties. Landlords who fail to address mould problems may face enforcement action under this Act.

Handling Mould Problems:

Tenant Communication: Tenants should report any mould-related issues to their landlord as soon as they become aware of them. Landlords should respond promptly to tenant complaints and take action to address mould problems in a timely manner.

Property Inspection: Landlords should conduct regular inspections of their rental properties to identify and address any issues that could contribute to mould growth. This may include checking for leaks, ensuring adequate ventilation, and addressing any signs of dampness.

Mould Remediation: If mould is found in a rental property, landlords should take steps to remediate the problem effectively. This may involve cleaning and removing mould from affected areas, repairing any water damage, and improving ventilation to prevent mould from returning.

Legal Obligations: Landlords should familiarise themselves with their legal obligations regarding mould in rental properties. In the UK, landlords can be held liable if they fail to address mould problems promptly and adequately, leading to potential legal disputes and financial consequences.


Landlords and tenants in the UK both play crucial roles in tackling mould problems in rental properties. By understanding their respective responsibilities and working together to address mould issues promptly and effectively, they can create safe and habitable living environments for all occupants. Effective communication, regular maintenance, and early intervention are key to preventing mould problems and ensuring the well-being of tenants.
