Awaab's Law Damp and Mould Timelines: Investigation and Repair Deadlines

Why Awaab’s Law Marks a Turning Point for Damp and Mould in Social Housing

Damp and mould have been a persistent problem in social housing for decades. But for too long, the response from landlords was inconsistent, some acted swiftly, others dragged their feet, and tenants had little legal recourse in the meantime. That changed on 27 October 2025, when Awaab’s Law came into force in England, introducing strict, enforceable timelines for investigating and repairing significant damp and mould in social rented properties.

The law takes its name from Awaab Ishak, a two-year-old boy who died in 2020 from a respiratory condition caused by prolonged mould exposure in his family’s social housing flat. His death became a catalyst for legislative change that housing campaigners had been pushing for years. Now, according to GOV.UK guidance for social landlords, social landlords must investigate reported damp and mould hazards within 14 days, begin repairs within a further 7 days, and complete emergency hazard repairs within 24 hours of a report being made.

These aren’t targets or guidelines. They’re legal obligations with real consequences for non-compliance.

I think what makes this legislation genuinely significant, beyond the headlines, is that it reframes damp and mould as a health hazard first and a maintenance issue second. That shift in framing matters. It changes how landlords must prioritise, resource, and document their response. And for tenants living with persistent damp, it provides something that’s been missing for too long: a clear, time-bound right to action.

This article breaks down the specific timelines landlords must meet, explains what counts as a “significant” damp and mould hazard under the law, and outlines the practical steps social housing providers need to take to stay compliant. Whether you’re a housing officer, a property manager, or a tenant trying to understand your rights, understanding these deadlines is now essential. Shelter England’s analysis of the new duties confirms that from October 2025, these responsibilities apply to all social landlords, no exceptions, no grace period.

The law is also set to expand. In 2026, the government will extend the regulations to cover a wider range of hazards beyond damp and mould, including excess cold. Getting systems in place now isn’t just about meeting today’s requirements, it’s about building the operational capacity to handle what’s coming next.

Damp and mould aren’t always emergencies, but that doesn’t mean landlords can take their time. Under Awaab’s Law, which came into force on 27 October 2025, significant damp and mould hazards trigger their own strict chain of deadlines. Miss one, and the legal consequences are real.

Here’s what the timeline actually looks like in practice.

Key Takeaways

• Understand the 10-Day Investigation Requirement: Landlords must initiate and complete investigations into significant damp and mould hazards within 10 working days of tenant notification to remain compliant with Awaab’s Law.

• Communicate Findings Promptly: After concluding the investigation, landlords have only three working days to provide tenants with a detailed written summary of the findings, including the action plan.

• Act Quickly on Repairs: Once a significant hazard is confirmed, safety works must begin immediately and be completed within five working days to avoid legal repercussions, including the provision of alternative accommodation.

• Document Everything: Comprehensive record-keeping of all communications and actions taken is essential for compliance and can protect landlords in case of future disputes.

• Prepare in Advance: Landlords should develop structured processes and relationships with contractors before complaints arise to ensure timely responses and adherence to the strict timelines set by Awaab’s Law.

Ten Working Days to Investigate Significant Hazards

Once a tenant reports significant damp or mould, the clock starts immediately. Government guidance on Awaab’s Law is clear: landlords must begin and complete their investigation within 10 working days, no delays, no waiting to see if the problem resolves itself.

Remote assessments are permitted in some circumstances, but tenants have the right to request an in-person investigation. If they do, that request effectively resets the 10-day window, which means landlords need to be ready to mobilise quickly.

What counts as a proper investigation? This is where many landlords fall short. It’s not enough to look at the visible mould on a wall and call it condensation. A compliant investigation means identifying the root cause, whether that’s faulty or absent ventilation, inadequate insulation, structural defects, or a combination of factors. Treating symptoms without understanding causes won’t satisfy the law, and it won’t solve the problem.

To ensure you meet these new deadlines and protect yourself legally, it’s crucial to understand the requirements around Awaab’s Law record keeping and compliance. Documentation of every step, from the date of notification to the findings of the investigation, is now an operational necessity.

Three Days to Share Investigation Results with Tenants

Once the investigation is complete, landlords have just three working days to provide tenants with a written summary of the findings. Three days. That’s a tight turnaround, and it demands that the investigation process itself produces clear, communicable outputs, not just internal notes.

Transparency here is non-negotiable. The written summary needs to tell tenants what was found, what the action plan is, and who they should contact if problems persist or worsen. Vague reassurances won’t cut it. Tenants are entitled to understand exactly what’s happening in their home and what steps are being taken to fix it.

I’d argue this three-day communication requirement is one of the most operationally challenging parts of the new legislation, not because the timeline is impossible, but because it demands a level of process discipline that many housing providers haven’t had to maintain before. Record-keeping of all written communications is now a compliance necessity, not a ‘nice-to-have’. If a dispute arises later, the paper trail will matter enormously.

Five Days to Complete Safety Works: Rapid Repair in the Real World

After a significant hazard has been identified, safety works must begin without delay and be completed within five working days. There’s an important exception: if the work genuinely requires specialist contractors or complex remediation, the five-day rule may not apply to completion, but landlords must still act promptly and document why additional time is needed.

The stakes for non-compliance are high. If works can’t be finished within the required timeframe, landlords are legally required to provide alternative accommodation at their own expense. That’s a significant cost, and a significant incentive to get the repairs done right and on time.

Think about what this looks like in practice. A landlord receives a report of serious mould caused by a persistent leak behind a bathroom wall. They investigate within the 10-day window, identify the leak as the root cause, share findings with the tenant within three working days, then mobilise a plumber and remediation team. Repairs begin the following morning and are completed by day three. The tenant is kept updated throughout. That’s the standard Awaab’s Law is setting, and it’s achievable, but only with the right systems and contractor relationships already in place.

Shelter England has noted that from 27 October 2025, these duties represent a fundamental shift in how social landlords must approach damp and mould complaints, moving from reactive, slow-moving responses to structured, time-bound accountability.

The message for landlords is straightforward: build the process before you need it. Waiting until a complaint arrives to figure out your investigation and repair workflows is how you miss deadlines. The landlords who will navigate Awaab’s Law most effectively are those who have already mapped out their response chains, briefed their contractors, and put strong documentation systems in place. Understanding how to manage tenant communication during repairs is equally important, as keeping tenants informed throughout the process reduces disputes and demonstrates compliance.
