Understanding Mould and Damp in Rental Properties
Mould and damp are common problems in many UK rental properties. Mould is a type of fungus that grows in moist conditions, often appearing as black, green, or white patches on walls, ceilings, or other surfaces. Damp refers to excess moisture in a building, which can lead to condensation, water stains, peeling wallpaper, and a musty smell. Both issues can damage property and pose health risks, especially for children, the elderly, and people with respiratory conditions.
There are several reasons why mould and damp develop in rented homes. Poor ventilation is a major factor – when windows are not opened regularly or extractor fans are not used, moisture from everyday activities like cooking, showering, or drying clothes indoors can build up. Leaks from roofs, windows, or plumbing are also a frequent cause, as water can seep into walls and floors over time. Structural problems, such as damaged guttering or rising damp from the ground, may also contribute. If you suspect a leak or water ingress, it’s important to address it quickly; you can learn more about related issues in our guide to leaks and roof repairs in rented homes.
Mould and damp are important issues for both tenants and landlords. For tenants, living in a damp or mouldy home can lead to health problems like asthma, allergic reactions, and infections. It can also damage belongings and make the home uncomfortable. For landlords, failing to deal with damp and mould can mean breaching legal obligations to provide a safe and habitable property. This can result in complaints, enforcement action, or even legal claims from tenants.
Understanding your rights and responsibilities is crucial. Both tenants and landlords have roles to play in preventing and tackling mould and damp. For a broader overview of your rights and the legal standards expected in rental properties, see our guide on rental conditions in the UK.
Legal Responsibilities of Landlords Regarding Mould and Damp
Landlords in the UK have a legal duty to keep rented properties in a good state of repair and free from health hazards, including mould and damp. This responsibility is set out in various laws, including the Housing Act 2004 and the Environmental Protection Act 1990. If you are a tenant, it’s important to know what your landlord must do to keep your home safe and healthy.
Keeping the Property Safe and Well-Maintained
A landlord must ensure that the structure and exterior of the property are kept in good repair. This includes making sure the roof, walls, windows, and doors are sound and weatherproof. Problems such as leaks, faulty gutters, or broken windows can let in moisture and lead to damp or mould. If any of these issues arise, your landlord is legally required to fix them.
For more details on these obligations, see our guide on Landlord Repair Responsibilities: What Tenants Need to Know in the UK.
Addressing Structural and Ventilation Issues
Mould and damp often start because of structural problems or poor ventilation. For example, rising damp can be caused by a damaged damp-proof course, while condensation might be made worse by a lack of extractor fans in kitchens or bathrooms. Landlords must address these underlying issues – not just clean away visible mould. If the property’s structure is contributing to the problem, it is the landlord’s duty to repair it.
If you suspect a structural issue is the cause, you can learn more in our section on Building Safety and Structural Issues.
Dealing with Leaks and Repairs
Leaks from roofs, pipes, or plumbing are a common cause of damp. Landlords are responsible for repairing these promptly to prevent further damage and health risks. If you notice a leak, report it to your landlord as soon as possible. For more information on how leaks should be handled, visit our page on Leaks and Roof Repairs in Rented Homes: Tenant and Landlord Rights.
Legal Standards and Health Hazards
The law treats mould and damp as potential health hazards. Under the Environmental Protection Act 1990, landlords must not allow conditions in their properties that could harm tenants’ health. Local councils can take action against landlords who fail to deal with serious mould or damp problems.
The Housing Health and Safety Rating System (HHSRS) is used by councils to assess hazards in rented homes, including excess damp and mould. This system helps determine whether a property is safe to live in and what action should be taken if it is not. For an overview of how this system works, see the Housing Health and Safety Rating System: introduction | Practical Law.
Practical Advice for Tenants
If you spot mould or damp, report it to your landlord in writing straight away. Keep records of all correspondence and take photos of the affected areas. If your landlord does not act, you may be able to contact your local council for help. Remember, your landlord cannot ignore problems that are their responsibility, especially when health is at risk.
Understanding your landlord’s legal duties can help you take the right steps to get mould and damp problems resolved quickly and effectively.
Tenant Responsibilities and Actions to Prevent Mould and Damp
As a tenant, you have a key role in helping to prevent mould and damp in your rented home. While your landlord is responsible for fixing structural problems and ensuring the property is fit to live in, tenants are expected to take reasonable steps to minimise the risk of mould and damp developing.
Ventilation and Heating
Good ventilation is essential. Try to open windows regularly, especially after cooking, showering, or drying clothes indoors. Use extractor fans if provided, and avoid blocking air vents. Keeping rooms well-ventilated helps moisture escape, reducing the chance of mould growth.
Heating also plays a part. Keeping your home at a consistent, reasonable temperature can help prevent condensation and damp. If you are unsure about the best way to use your heating system, or if you have concerns about your rights to adequate heating and hot water, see our guidance on heating and hot water responsibilities. For tips on balancing comfort and cost, you might also find it helpful to read about whether it’s cheaper to have the heating on all the time.
Reporting Problems Promptly
If you notice signs of damp or mould – such as musty smells, black spots on walls, or peeling wallpaper – report the problem to your landlord or letting agent as soon as possible. Early reporting helps prevent the issue from getting worse and ensures your landlord is aware of their duty to address it. If the damp is caused by a leak or a structural issue, such as a faulty roof, you should notify your landlord promptly. For more on what to do if leaks or roof damage are involved, see our guide to leaks and roof repairs in rented homes.
Taking Reasonable Care
Tenants are expected to take reasonable care of the property. This means not drying clothes on radiators without good ventilation, wiping away condensation from windows, and not overfilling cupboards or wardrobes, which can trap moisture. However, you are not responsible for fixing structural faults or dealing with issues caused by disrepair.
For a comprehensive overview of your rights and responsibilities, including your obligations around repairs and maintenance, you can refer to A tenant’s guide to repairs and maintenance from the Tenancy Deposit Scheme.
By taking these steps, you can help keep your home healthy and comfortable, and ensure any issues are dealt with before they become serious.
Health Risks and Impact of Mould and Damp
Exposure to mould and damp in the home can cause a range of health problems, especially for vulnerable groups. Breathing in mould spores or living in damp conditions may lead to coughing, wheezing, throat irritation, and worsening of asthma or allergies. Children, older adults, and people with weakened immune systems are at particular risk. In some cases, mould exposure can trigger more serious respiratory infections.
Both tenants and landlords should take these risks seriously. Health problems linked to mould and damp can develop quickly and may become severe if the underlying issues are not addressed. For landlords, ignoring these problems could result in legal action and damage to the property. For tenants, living in a damp or mouldy environment can make daily life uncomfortable and may lead to long-term health concerns.
If you or anyone in your household starts to experience symptoms like persistent coughing, shortness of breath, or skin irritation, it is important to seek medical advice. If you have existing health conditions such as asthma, be extra cautious and speak to your GP if your symptoms get worse. The UK government offers detailed guidance on understanding and addressing the health risks of damp and mould in the home, including steps you can take to protect yourself and your family.
It is also wise to investigate the root cause of damp or mould as soon as possible. Sometimes, issues like leaks or poor ventilation are to blame. For further information on how leaks and structural problems can contribute to damp, see our guide on leaks and roof repairs in rented homes. Taking early action can help prevent health risks and avoid more costly repairs in the future.
What to Do If You Have Mould or Damp Problems
If you notice mould or damp in your rented home, it’s important to act quickly. Mould and damp can damage your belongings and harm your health, so don’t ignore the problem.
1. Report the Issue to Your Landlord
Start by informing your landlord or letting agent as soon as you spot signs of mould or damp. Put your report in writing, such as by email or letter, so you have a clear record. Describe the problem in detail, including where it is, how severe it seems, and when you first noticed it. If you can, attach photos to show the extent of the issue.
If you are unsure how to structure your request, you can use a sample repair request letter to formally notify your landlord. This helps ensure your communication is clear and covers all the necessary details.
2. Keep Records and Gather Evidence
Always keep copies of any messages or letters you send and receive. It’s also a good idea to take dated photographs of the affected areas. If the problem gets worse, update your records with new photos and notes. This evidence can be vital if you need to prove that you reported the issue or if you have to take further action.
3. Request Repairs or a Professional Inspection
Your landlord is legally responsible for fixing problems that make your home unsafe or unhealthy, including serious mould and damp. If the issue is linked to leaks or structural faults, your landlord should arrange repairs promptly. Sometimes, a professional inspection may be needed to identify the cause, especially if the source isn’t obvious.
For more on your rights and what landlords must do, see our guide to repairs and maintenance in rented homes. If you suspect the damp is due to a leak or roof problem, you might also find our page on leaks and roof repairs helpful.
4. What If Your Landlord Does Not Act?
If your landlord ignores your request or refuses to deal with the problem, don’t give up. Follow up in writing, reminding them of their duty to keep the property fit for living. If there is still no response, you can escalate the issue. Guidance on how to complain to your landlord covers the steps you can take, including contacting your local council or seeking legal advice.
Remember, you should never stop paying your rent, even if your landlord hasn’t fixed the problem. Withholding rent can put you at risk of eviction. Instead, focus on documenting the issue and following the correct process to get it resolved.
Resolving Disputes and Getting Further Help
If your landlord does not address mould or damp problems after you report them, you have several options to help resolve the issue.
First, keep a record of all your communications with your landlord, including emails and letters, as well as photos of the affected areas. This evidence can be useful if you need to escalate the matter.
If your landlord continues to ignore the problem or refuses to carry out necessary repairs, you can contact your local council’s environmental health team. Councils have the power to inspect your home and can order landlords to fix serious health and safety hazards, including damp and mould. To find out how to make a complaint, visit the official government guidance on Council housing: Complaints – GOV.UK.
Tenant support organisations, such as Shelter or Citizens Advice, can offer free guidance on your rights and help you understand your options. You may also be eligible for legal aid if your health or safety is at risk due to poor housing conditions.
In some cases, mediation can help you and your landlord reach an agreement without going to court. If all else fails, you might consider taking legal action. This could involve making a claim for repairs or compensation through the courts, especially if the mould or damp has caused damage to your belongings or affected your health.

Taking action can feel daunting, but support is available to help you ensure your home is safe and healthy.
Preventing Mould and Damp Through Property Maintenance
Proper property maintenance is key to preventing mould and damp in rented homes. Both tenants and landlords have a role to play in keeping the property safe, dry, and healthy.
Plumbing and Water System Upkeep
Leaking pipes, faulty taps, and blocked drains are common causes of damp. Regular checks and prompt repairs help avoid water escaping into walls and floors. Landlords should arrange for professional inspections and fix any issues quickly. Tenants should report leaks or plumbing problems as soon as they notice them. For more on how plumbing responsibilities are divided, see our guide on Understanding UK Plumbing Laws: Your Guide to Water System Rules.
Sometimes, damp is caused by problems with the roof or guttering. Missing tiles or blocked gutters can let water in, leading to mould growth. If you spot water stains on ceilings or walls, it could be a sign of a leak. Find out more about your rights and steps to take in our section on Leaks and Roof Repairs in Rented Homes: Tenant and Landlord Rights.
Pest Control and Property Health
Pests like rodents and insects can damage property and create conditions where mould thrives. For example, rats may chew through pipes, causing leaks, while insects can block ventilation. Keeping the property clean and dealing with infestations quickly is crucial. Landlords are usually responsible for making sure the property is free from pests at the start of the tenancy, while tenants should avoid attracting pests through poor housekeeping. Learn more about legal duties in our page on Pest Control in UK Rentals: Legal Duties for Landlords and Tenants.
Utilities, Energy Supply, and Condensation
Adequate heating and ventilation help control condensation, one of the main causes of mould. If the heating does not work or there is poor insulation, moisture can build up on walls and windows. Landlords must ensure the property has a reliable supply of gas, electricity, and heating. Tenants should use heating and ventilation systems as intended. If you have questions about your rights regarding energy supply or utility maintenance, read our guide on Utilities and Energy Supply in UK Rentals: Tenant and Landlord Rights.
By staying on top of maintenance, both landlords and tenants can help prevent mould and damp, protecting the property and everyone’s health.
Additional Resources and Insurance Considerations
Dealing with mould and damp in a rented home can be stressful, especially when it comes to repairs and potential damage to your belongings. Understanding how home insurance works in these situations, and where to find further support, can make a big difference.
Home Insurance and Mould or Damp Damage
Many tenants and landlords wonder if home insurance covers damage caused by mould or damp. The answer depends on the cause and the type of policy in place. Standard contents insurance policies often exclude gradual damage from mould or damp, especially if it results from condensation or lack of ventilation. However, if the mould is caused by a sudden event – like a burst pipe or a leaking roof – your insurance might cover repairs and replacement of damaged items.
Landlords should also check their buildings insurance, as some policies may help with structural repairs if the damp is linked to issues like leaks or storm damage. It’s important to read the policy details carefully and ask your insurer about what is and isn’t covered. For a full breakdown of what home insurance typically covers, including mould and damp issues, see our guide on Home Insurance in the UK: What It Covers, Legal Duties and Key Tips.
Choosing the Right Insurance Policy
When selecting an insurance policy, look for clear terms about damp and mould. Some policies offer optional add-ons for accidental damage or emergency repairs, which may include cover for leaks and the resulting damp. Always declare any existing mould or damp problems when applying for insurance, as failure to do so could invalidate your cover.
If you’re a tenant, consider contents insurance that protects your personal items from water damage. Landlords should ensure their buildings insurance covers common causes of damp, such as leaking roofs or faulty plumbing. For more on landlord and tenant responsibilities around leaks and repairs, see our resource on Leaks and Roof Repairs in Rented Homes: Tenant and Landlord Rights.
Where to Find More Information and Support
If you’re facing mould or damp issues, you don’t have to handle it alone. Local councils, housing charities, and Citizens Advice can offer guidance. Your letting agent or landlord should also be your first point of contact for repairs.
