Tenant Lifestyle Myth: Why Landlords Must Fix Root Causes Under Awaab's Law

Why Awaab’s Law Changes Everything for Landlords, and Why Ventilation Is at the Heart of It

For decades, a convenient narrative has circulated through the housing sector: that damp and mould in rented properties are largely the tenant’s fault. Too much cooking. Too many showers. Not enough windows opened. It’s a story that has let structural problems go unfixed for years, and in the worst cases, it has cost lives.

Awaab Ishak was two years old when he died in December 2020. The cause was a respiratory condition directly linked to mould in the social housing property his family had repeatedly reported. His death, and the inquest that followed, exposed something the housing sector could no longer ignore: that blaming tenants for conditions caused by inadequate ventilation and insulation isn’t just unfair, it’s dangerous.

Awaab’s Law, which came into effect on 27 October 2025, now places a legal duty on social landlords to investigate and fix hazards related to damp and mould within strict timeframes. Emergency hazards must be addressed within 24 hours. Significant hazards must be investigated within 14 days and repaired within a further seven. The law doesn’t offer a defence of “the tenants were cooking too much.” It asks a harder, more honest question: is the building actually fit for purpose?

Since the law came into force, the effects have been immediate. Inside Housing reports a sharp rise in emergency hazard reports from social landlords, a signal that properties which have long harboured moisture problems are finally being surfaced and scrutinised.

This article looks at the root causes behind damp and mould, why the “tenant lifestyle” explanation so often misses the point, and what landlords and developers need to understand about ventilation and insulation if they’re going to meet both the letter and the spirit of this law. I’ve spent years working on ventilation solutions in residential properties, and the pattern I see again and again is this: where buildings are properly designed to manage moisture at source, the problem largely disappears. Where they aren’t, no amount of tenant behaviour change makes a meaningful difference. For a deeper understanding of how these issues intersect with broader housing standards, see our guide on compliance with housing regulations and the role of building inspections in identifying defects.

Understanding that distinction, between lifestyle and structure, is exactly what Awaab’s Law now demands.

For years, a particular response echoed through housing offices whenever tenants reported damp or mould: “It’s condensation from cooking and drying clothes.” That explanation, convenient, cheap, and almost entirely unverifiable, allowed landlords to close cases without spending a penny on the property itself. Awaab’s Law has changed that calculation entirely.

Why ‘Lifestyle’ is No Longer an Excuse

Under the current regulatory framework, landlords can no longer attribute damp and mould solely to how tenants live. Awaab’s Law guidance from the government is explicit: when a hazard is reported, the landlord must investigate its root cause, not issue lifestyle advice and consider the matter closed.

This is a genuine structural shift. The old defence, “the tenant generates too much moisture”, has been effectively wiped out as a standalone justification for inaction. Landlords, both social and private, are now required to assume responsibility, open a proper investigation, and document what they find. The burden of proof has flipped. You don’t get to blame the occupant without first ruling out every structural and systemic cause.

Honestly, this was overdue. I’ve spoken with tenants who received leaflets about opening windows while living in properties with no functioning extractor fans and single-glazed windows facing north. The advice wasn’t wrong exactly, ventilation does matter, but it was being used as a substitute for actual remediation. That approach won’t hold up any more.

Root Cause: What Landlords Really Need to Address

So what should landlords actually be investigating? The checklist is more technical than many property managers have historically been comfortable with. Missing or inadequate ventilation, damaged or absent insulation, failing damp-proof courses, and poorly maintained building fabric are the starting points, not the tenant’s cooking habits.

Here’s the thing: moisture problems in residential buildings very often trace back to construction flaws or systems that have degraded over time, not to how people live in a space. A family of four will produce moisture. That’s unavoidable. But a well-designed, properly maintained building is engineered to handle that load. When it can’t, the building has a problem, not the family.

A straightforward example makes this concrete. Bathrooms without functioning extractor fans are one of the most common findings in damp investigations. The fix is relatively simple and inexpensive. The impact, though, is significant: without mechanical extraction, humid air from showers has nowhere to go except into the fabric of the building. Mould follows. And yet, in many cases, tenants in those properties were being told to open a window rather than having the fan repaired or installed. That’s the kind of gap Awaab’s Law is designed to close.

The Housing Ombudsman’s learning resources on Awaab’s Law reinforce this point, drawing on casework that consistently shows inadequate ventilation and building defects, not tenant behaviour, as the primary drivers of hazardous damp conditions.

Mandatory Upgrades: When Legal Duties Trigger Mechanical Interventions

Once an investigation identifies a structural or systemic cause, the legal duty to act kicks in. Where a building lacks functioning ventilation or has faulty insulation, landlords are now required to install or replace those systems, not advise tenants to compensate for the gap through their behaviour.

The Regulator of Social Housing has set out minimum standards that define what adequate ventilation and insulation look like in practice. These aren’t aspirational guidelines. They’re compliance benchmarks. Falling short of them, particularly after a hazard has been reported and investigated, creates direct exposure to non-compliance findings, and the enforcement consequences that follow.

What this means practically is that landlords need to move from a reactive, complaint-by-complaint posture to a more systematic one. If a property has a pattern of damp reports, that’s a signal worth investigating at a building level, not just a unit level. Are the extractor fans in that block up to specification? Is the insulation in the external walls performing as it should? Has the building’s ventilation strategy kept pace with any retrofitting work done over the years?

These are engineering questions, and they require engineering answers. I’d argue that landlords who invest in getting ahead of this, commissioning proper ventilation assessments and insulation surveys now, will find compliance far less disruptive than those who wait for enforcement action to force their hand. The Final Stage Impact Assessment for Awaab’s Law acknowledges the resource demands this places on the sector, but the direction of travel is clear and the timelines are already live.

The bottom line: the lifestyle myth is legally untenable now. Root causes, ventilation, insulation, building fabric, are where the responsibility sits, and where the solutions need to be found.

Frequently Asked Questions

What is Awaab’s Law and how does it impact landlords?
Awaab’s Law mandates that landlords must investigate the root causes of damp and mould rather than attributing these issues to tenant lifestyle. This means landlords are now responsible for ensuring proper ventilation, insulation, and other structural elements are in good condition to prevent hazardous living conditions.

How can landlords ensure compliance with Awaab’s Law?
To comply with Awaab’s Law, landlords should conduct thorough investigations into reported damp issues, focusing on potential structural problems such as inadequate ventilation or damaged insulation. Regular maintenance checks and updates to building systems can help prevent non-compliance and improve tenant safety.

What are common root causes of damp that landlords should address?
Common root causes of damp include inadequate ventilation, faulty insulation, and structural defects. Landlords should prioritize fixing these issues to create a safe living environment, as these problems are often the true drivers of damp conditions rather than tenant behavior.

How does Awaab’s Law change the approach to tenant complaints about damp?
Under Awaab’s Law, landlords can no longer dismiss tenant complaints about damp as merely a result of lifestyle choices. Instead, they must take each report seriously and investigate potential structural issues, ensuring that tenants live in safe and healthy conditions.

What should landlords do if they discover ventilation or insulation issues?
If ventilation or insulation issues are identified, landlords are legally obligated to address these problems promptly. This may involve installing or repairing mechanical ventilation systems and improving insulation to meet compliance standards set forth by the Regulator of Social Housing.

Common Mistakes to Avoid

Mistake 1: Ignoring Ventilation Needs

One common mistake landlords make is neglecting the ventilation requirements of their properties. Failing to install or maintain adequate ventilation systems can lead to persistent damp and mould issues, which are now the landlord’s responsibility under Awaab’s Law. To avoid this, ensure that all properties are equipped with functional extractor fans and that ventilation strategies are regularly assessed and updated.

Mistake 2: Overlooking Insulation Quality

Many landlords underestimate the importance of proper insulation in preventing damp issues. Insufficient or damaged insulation can exacerbate moisture problems, leading to costly repairs and potential legal repercussions. Conduct regular insulation assessments and replace or upgrade insulation materials as needed to maintain compliance and protect your property.

Mistake 3: Relying on Tenant Behavior Justifications

Landlords often fall into the trap of attributing damp and mould problems solely to tenant behavior, such as cooking or drying clothes. This mindset disregards the structural issues that may be the true root causes. Instead, focus on thorough investigations of the property to identify and address underlying problems rather than blaming tenant actions.

Mistake 4: Delaying Property Assessments

Another mistake is postponing necessary property assessments and maintenance until tenant complaints arise. This reactive approach can lead to significant compliance issues under Awaab’s Law. Proactively schedule regular inspections and maintenance to identify and rectify potential hazards before they escalate into tenant complaints.

Mistake 5: Failing to Document Investigations

Landlords sometimes neglect to keep detailed records of their investigations into reported damp issues, which can lead to compliance failures. Proper documentation is essential for demonstrating that you have taken the necessary steps to investigate and address root causes. Implement a systematic approach to record all findings, actions taken, and communications with tenants to ensure compliance and accountability.
