Awaab’s Law - Why ventilation is central to healthy homes By John Felgate, Managing Director, STIEBEL ELTRON UK

Instead, landlords now have a clear legal duty to investigate and resolve issues, marking a decisive move toward accountability and prevention in the housing sector. 

The law changes what is expected of those who let, manage and build homes, delivering stringent requirements which must be met when complaints are raised by a resident. 

Remedial work must be carried out within mandated deadlines and, where homes are deemed unsafe to occupy, the responsibility of finding alternative accommodation will fall on the landlord.

Crucially, any organisation or private letter which fails to meet these new responsibilities runs the risk of suffering significant legal and reputational ramifications. 

From reaction to prevention

The true power of Awaab’s Law is not in the issues it will resolve, but in the mindset shift it will inspire. 

For responsible developers and landlords, house management will shift away from reactive repairs towards a more preventative, resident-focused model. 

With scrutiny intensified, it will have a significant impact on the way in which new homes are designed and built. Build quality, airtightness and ventilation will no longer be matters of best practice but will become fundamental elements of legal responsibility. 

For those developers who fail to consider how moisture moves through a building or how fresh air is supplied and stale air removed, they risk creating homes which quickly fall short of both regulatory expectations and the needs of residents. 

Awaab’s Law brings into sharp focus the critical role of preventing the conditions it is designed to eliminate. Damp and mould are rarely a cosmetic issue, but a visible result of fundamental problems within a dwelling. 

Whether it is trapped moisture, poor airflow, insufficient air changes, or all the above, mould is the product of a contributing factor. 

It is not something which only affects older buildings too. Modern housing, which is increasingly airtight in the pursuit of energy efficiency, can unintentionally trap humidity and stale air indoors. Everyday activities such as cooking,  showering and drying clothes release large amounts of vapour   into the air, which condenses on cold surfaces to create an environment where mould thrives. 

Mould spores These pollutants have a detrimental effect on human health, with prolonged exposure linked to respiratory conditions such as asthma, bronchitis and persistent coughing. It also risks exacerbating existing allergies and compromising immune systems, particularly in children, older people and those with underlying health conditions. 

Meanwhile, the build-up of fine particulates and carbon dioxide indoors can contribute to headaches, fatigue, poor sleep and reduced cognitive function. 

For landlords and developers, moving to a preventative approach is far more effective and cost-efficient than repeated, reactive repairs, and shows a heightened duty of care to residents.

Delivering healthy homes with ventilation

This is where whole-house ventilation systems play an important role, helping to continuously extract moist, stale air from areas such as kitchens and bathrooms while supplying fresh, filtered air to living spaces and bedrooms. 

They operate at continuously low levels, rather than intermittently. This helps manage humidity while improving air quality by diluting and removing airborne pollutants which stem from everyday activities.   

Additionally, by extracting moisture-laden air from a home, modern systems recover heat from outgoing air to warm the fresh air, maintaining an ambient temperature which reduces a reliance on additional heating measures.

The result is a healthier indoor environment which doesn’t compromise energy efficiency. At a time when fuel costs and carbon reduction targets across Britain’s homes remain high on the national agenda, the importance of this cannot be overstated.

While Awaab’s Law sets out new regulations, it represents an opportunity for the housing sector to deliver a fundamental shift in the way it approaches safety and responsibility, moving beyond minimum standards to embed health-first thinking into housing. 

By prioritising robust ventilation systems, the housing industry and landlords can ensure that every home is not only warm and energy efficient, but genuinely safe and fit for purpose.
