Mould Detection and Prevention: A Critical Aspect of Property Management

9 September 2024

Damp and mould are becoming a significant problem across UK households – especially in social housing. They aren’t just unsightly issues: they pose significant health risks to residents and can even cause structural damage if left unaddressed. For social housing providers, property managers, and landlords, tackling mould is essential not only to ensure tenant well-being but also to maintain property standards and stay compliant with ever-changing legal obligations. This blog explores the dangers of mould, the legal responsibilities of landlords, and how Resisure’s advanced mould detection and prevention technology can help property providers stay ahead of these issues to provide a safe and healthy living environment that tenants deserve.

The Growing Problem of Mould in the UK

Mould is becoming an increasingly common issue in the UK. Data from various surveys highlight that 29% of the population experiences mould in their homes frequently or occasionally​, and around 2 million people live in homes with significant damp and mould issues highlighting just how pervasive the issue is. This is particularly prevalent across the rented sector, with 11% of private rental homes and 4% of social housing units being affected by damp and mould​.

What’s more, the problem is showing no signs of abating, with the Housing Ombudsman reporting a 99% increase in complaints about damp and mould was recorded between 2021 to 2022, indicating the scale of the problem​. It has never been clearer that the time to act against damp and mould is now.

The Health and Structural Risks of Mould

Mould growth isn’t just a visual issue that can make walls and ceilings look unattractive – there are severe health implications, especially for vulnerable groups such as children, the elderly, and those with respiratory conditions. Studies have shown that living in damp and mouldy conditions increases the risk of asthma, allergic rhinitis, and respiratory infections. Dampness in a property can also lead to long-term structural damage: if not detected early, moisture can seep into walls, foundations, and wooden structures, leading to costly repairs. Property managers and social housing providers who fail to address these issues promptly face growing repair costs and dissatisfied tenants, both of which can harm their reputation and increase tenant turnover.

Legal Responsibilities and Awaab’s Law

Recent high-profile cases, such as the tragic death of two-year-old Awaab Ishak due to long-term mould exposure, have highlighted the critical need for landlords to take damp and mould issues seriously. The introduction of Awaab’s Law has tightened regulations, making it mandatory for landlords and social housing providers to address mould complaints quickly and effectively. This law has been part of a broader government effort to improve living conditions, especially in rented accommodations, by holding landlords to account when damp and mould are present.

Landlords are now legally required to ensure their properties are “fit for human habitation,” a term that encompasses freedom from damp and mould. Failure to comply with these regulations not only results in legal repercussions but also jeopardizes the health of tenants​. Now, tenants can take legal action against their landlords if they do not promptly and effectively address issues such as damp and mould in their household – this exposes landlords to costly fines and can even result in court action. This is why preventing mould growth across your portfolio is more important than ever before.

Why Mould Detection And Prevention Detection Matters

One of the biggest challenges in managing mould is detecting it early enough to prevent major disrepair. Since mould thrives in hidden or hard-to-reach places, it often goes undetected until it becomes visible, by which time it can already have caused significant harm. The Resisure’s monitoring platform has the ability to track internal environmental conditions continuously allowing the property manager or landlord to take preventive measures long before mould becomes a serious problem. Moreover, with our detailed reporting, landlords can have accountability and transparency when addressing tenant concerns, which is crucial in light of the Homes (Fitness for Human Habitation) Act, keeping you compliant.

How Resisure Can Help: The Technology Behind Mould Detection

At Resisure, we understand the challenges landlords and property managers face in detecting and addressing mould before it becomes a bigger problem – we know how difficult it can be to keep tabs on a large portfolio of properties, and understand that the growing threat of damp and mould across rental homes can be a particularly large concern. That’s why we created Resisure to give landlords, property managers and housing associations the power to prevent damp and mould growth before it starts to have a dangerous impact on your properties and your tenants. 

Our innovative property monitoring platform offers real-time insights of key internal environmental factors like temperature, humidity and air-quality all of which are early indicators of mould growth. We have developed and created the Resisure Mould Index, in conjunction with research from the University of Exeter, to analyse these data insights and generate weekly reports that can alert landlords and property managers to potential risks before they escalate. By installing our technology within properties, property managers and landlords can monitor environmental trends and identify patterns that might otherwise go unnoticed.

Harness The Power Of Mould Prevention With Resisure

For landlords and property managers, staying ahead of mould growth is not just about preserving property value—it’s about protecting tenant health and avoiding legal pitfalls. Resisure’s advanced monitoring technology offers a proactive solution that ensures properties remain safe, compliant, and mould-free. In today’s rental market, where more than half of people affected by mould live in privately rented, local authority, or housing association accommodations​, investing in a reliable mould detection system like Resisure’s is a sensible investment in your portfolio and in your tenants’ well-being. 

Don’t wait for complaints or costly repairs—take action now to protect both your properties and your tenants. Get in touch with us today to find out how the power of preventative property technology can transform your portfolio:


What is mould detection?

Mould detection is the process of identifying environmental risks before visible growth actually occurs. While traditional methods rely on physical inspections once a problem has started, proactive detection uses smart sensors to monitor atmospheric conditions in real time. By identifying high humidity and persistent condensation early, you can act before the building fabric is compromised or a resident’s health is affected.

Why is mould prevention important?

Prevention is far more cost-effective and ethical than remediation. Once mould is visible, it has often already begun to impact indoor air quality and can trigger respiratory issues for tenants. By preventing its growth, landlords protect the long-term value of their assets, avoid expensive deep-cleaning or replastering costs, and ensure they remain fully compliant with modern safety legislation like Awaab’s Law.

How can landlords implement mould prevention?

Effective prevention starts with a combination of structural maintenance and environmental control. Landlords should ensure all properties have adequate, functioning ventilation systems and sufficient insulation to eliminate cold spots. Implementing monitoring technology like Resisure provides the final layer of protection, offering the objective data needed to manage humidity levels and intervene the moment a property falls outside of healthy parameters.
