Awaab’s Law: Damp, Mould and What Social Housing Providers Need to Know
Updated: Sep 2
Awaab’s Law has changed how damp, mould and other serious housing hazards must be managed within social housing in England.
Since 27 October 2025, social landlords have been subject to legally enforceable timeframes for investigating and addressing significant damp and mould hazards and all emergency hazards.
Named after two-year-old Awaab Ishak, who tragically died following prolonged exposure to mould in his home, the legislation reinforces the importance of taking damp and mould seriously - investigating the cause, protecting occupants and taking appropriate action promptly.
For housing associations, local authorities and property management teams, this means having robust procedures in place to identify, investigate, repair and remediate affected properties.
What Does Awaab’s Law Require?
Under the first phase of Awaab’s Law, social landlords must meet specific timeframes when potential hazards are reported or identified.
Significant damp and mould hazards
Where a potential significant damp or mould hazard is identified, landlords must:
Investigate within 10 working days of becoming aware of the potential hazard
Provide the tenant with a written summary within 3 working days of the investigation concluding
Where a significant hazard is identified, complete the necessary relevant safety work within 5 working days of the investigation concluding
Take appropriate steps to address further work required to prevent the hazard recurring
Emergency hazards
Where a hazard presents an imminent and significant risk of harm, landlords must investigate and undertake relevant safety work within 24 hours of becoming aware of it.
Where a property cannot be made safe within the required timeframe, the landlord may also be required to provide suitable alternative accommodation.
Vulnerable Tenants and Awaab’s Law
The individual circumstances of the people living in the property matter.
Age, health and other relevant factors can influence the level of risk posed by damp, mould or another housing hazard.
This means landlords need to consider not only the condition of the property, but also the potential impact of that condition on the particular occupants.
Awaab’s Law Is Expanding
The legislation is being introduced in phases.
Phase 1 – from 27 October 2025
Covers significant damp and mould hazards and all emergency hazards.
Phase 2 – from 30 November 2026
The significant-hazard requirements extend to a wider range of housing hazards, including excess cold and heat, falls, fire and explosion, electrical hazards and structural collapse.
A further phase is intended to extend the requirements to the remaining Housing Health and Safety Rating System (HHSRS) hazards, with overcrowding excluded.
For housing providers, this makes effective hazard management, contractor availability, communication and record keeping increasingly important.
Damp and Mould: Remediation Must Go Beyond the Visible Problem
Mould should not simply be cleaned away or painted over without investigating why it developed.
Common contributing factors can include:
Water ingress
Plumbing leaks
Condensation
Inadequate ventilation
Excess humidity
Thermal bridging
Building defects
Previous water damage
The underlying moisture source or building defect needs to be identified and appropriately addressed.
Once this is underway, specialist mould remediation can deal with the resulting fungal contamination.
This distinction is important: remediation treats the contamination; it does not replace the need to correct the conditions that caused it.
How BioSweep UK Supports Social Housing Providers
BioSweep UK provides specialist mould remediation and suppression, decontamination, environmental sampling and odour removal services for housing providers and property professionals.
We can work alongside housing teams, surveyors, building contractors, damp specialists and restoration professionals as part of a coordinated response to affected properties.
Depending on the circumstances, our services can include:
Environmental air and surface sampling
Independent laboratory analysis
Detailed surface cleansing
Mould remediation and suppression
Reduction of residual fungal contamination and microbial load
BioSweep® treatment following appropriate preparation
Post-remediation environmental sampling
Treatment and completion reporting
Specialist odour removal
BioSweep does not replace the role of building surveyors, ventilation specialists, damp professionals or contractors responsible for identifying and correcting structural or moisture-related defects.
Instead, we provide the specialist environmental remediation and verification support required where mould or associated contamination remains within the property.
Environmental Sampling and Verification
Where appropriate, environmental sampling can provide useful supporting evidence before or after remediation.
BioSweep can undertake air and surface sampling, with samples submitted to an independent laboratory for analysis.
This can help housing providers:
Establish environmental conditions within sampled areas
Support remediation decisions
Compare pre- and post-treatment findings
Maintain supporting evidence within property records
Demonstrate the environmental remediation work undertaken
Laboratory results relate specifically to the samples, locations and conditions tested. They should therefore be considered alongside the wider property investigation rather than used in isolation as certification of whole-property conditions or legal compliance.
A Practical Damp & Mould Response
A robust response should follow a clear process:
Report → Triage → Investigate → Identify Cause → Make Safe → Repair → Remediate → Verify Where Appropriate → Monitor
This approach separates the different responsibilities involved.
For example, a building surveyor or appropriate property professional may investigate the cause of water ingress or condensation; contractors may undertake necessary repairs; and
BioSweep can subsequently address the resulting environmental contamination.
This helps avoid the common problem of treating visible mould without resolving why it developed in the first place.
What Should Housing Providers Be Doing Now?
Review your response procedures
Ensure reports of damp and mould are captured, assessed and escalated promptly.
Understand the statutory timeframes
Relevant employees, property managers and contractors should understand the applicable deadlines and when they begin.
Consider the occupants
Risk assessments should take account of the people actually living within the property and any circumstances that may increase their susceptibility to harm.
Identify the underlying cause
Mould remediation should be coordinated with appropriate investigation and correction of leaks, ventilation issues, condensation, water ingress or other contributing factors.
Establish access to specialist contractors
Having remediation and environmental specialists available can help avoid delays once investigation and repair requirements have been established.
Maintain clear records
Record reports, investigations, communications, photographs, works undertaken, dates, laboratory results and post-remediation findings where applicable.
Does Awaab’s Law Apply to Private Landlords?
The regulations currently in force apply to social housing in England.
Legislation provides for Awaab’s Law requirements to be extended into the private rented sector, but private landlords should not currently be described as being subject to the same Awaab’s Law social-housing timeframes.
Regardless of tenure, however, damp and mould can present significant property and occupant risks and should be investigated and addressed appropriately.
Can BioSweep Make a Property Awaab’s Law Compliant?
Awaab’s Law compliance is the responsibility of the landlord and involves more than mould remediation alone.
BioSweep therefore does not certify a landlord or property as “Awaab’s Law compliant”.
What we can provide is specialist environmental assessment, remediation, sampling and documentation that can form an important part of the landlord’s wider response and property records.
Does BioSweep Eliminate All Mould Spores?
No responsible mould remediation service should promise to create a completely spore-free environment. Fungal spores occur naturally in outdoor and indoor environments.
BioSweep's approach is designed to remediate and suppress mould contamination and reduce microbial load, alongside appropriate action to correct the underlying moisture source.
Where required, post-remediation environmental sampling can provide further information about conditions within the areas tested.
Can BioSweep Prevent Mould From Returning?
Successful long-term mould management depends on controlling the conditions that allowed mould to develop.
BioSweep can address existing fungal contamination, but leaks, water ingress, condensation, inadequate ventilation, excess humidity, thermal bridging or other building-related causes must also be investigated and corrected.
Without addressing the underlying cause, mould may return.
