Awaab Ishak was two years old when prolonged exposure to mould in his family's Rochdale flat killed him in 2020. The coroner ruled his death entirely preventable, caused by a hazard his landlord had been told about again and again. The law that now carries his name turns that failure into binding duties: fixed timescales for investigating and fixing damp and mould, starting with social housing from October 2025 and extending to the private rented sector under the Renters' Rights Act. If you're a landlord, or you work in the trade that fixes the underlying physics, 2026 is the year this stops being a headline and becomes your working reality.
What the law actually requires
Awaab's Law writes response deadlines straight into tenancy obligations. Emergency hazards have to be dealt with within 24 hours. Significant damp and mould hazards must be investigated within a fixed number of days of being reported, the findings shared with the tenant in writing, and remedial work started and finished inside prescribed windows. It also kills off the classic deflection: blaming 'tenant lifestyle' is no longer a defence where the building's fabric and ventilation make condensation inevitable. Social landlords are in scope first. Private landlords should treat the extension as imminent and the standard as already set, because courts, insurers and the Housing Ombudsman are benchmarking against it now. Do check the current commencement details for your sector, but plan as if the clock is already running. Morally and commercially, it is.
Why mould is usually a window story
Most rental mould is condensation mould, and condensation goes hunting for cold surfaces. Moisture from cooking, showers and simple breathing finds the coldest square metre in the room and beads on it. Nine times out of ten, that square metre is glazing or the reveal around it. Single glazing runs cold. So do failed 1990s units and blown sealed units. Perished seals leak, and painted-shut vents take away the escape route. The full physics is here, but the landlord translation is blunt: you can't compliance-clean your way out of cold glass. Mould wiped off a freezing reveal comes back within weeks, and now there's a documented report trail sitting behind it.
The compliant fix, layer by layer
- Immediate (days): treat existing growth with fungicidal wash and document it; check the extractor fans actually work; unblock trickle vents and show tenants how to use them.
- Root cause (weeks): swap failed sealed units for modern Low-E warm-edge glass, which lifts inner surfaces above the dew point; re-gasket draughty frames; fit humidity-tracking extractors in wet rooms.
- Structural (planned): where whole windows are pre-2002 or failing, replace them with A++ units and integrated ventilation. That's the fix that ends the cycle, helps the EPC toward the C deadline, and usually costs less than one void period plus one tribunal.
- Paper trail throughout: dated photos, invoices, tenant communications. Under fixed timescales, the documentation is half the compliance.
The portfolio-level play
Reactive compliance is the expensive kind. Every tenant report now starts a statutory clock, and work done against a deadline gets billed at rush prices. There's a better way: run an audit-led programme instead. Inspect every unit's glazing, vents and extract fans once. Rank properties by condensation risk (single glazing, north-facing bedrooms, a known complaint history). Then schedule glazing and ventilation works across quiet periods and tax years. Landlords who ran this play ahead of the social-housing deadline report the unglamorous payoff: no clocks ever start, because the hazards never form. It's the same maintenance-beats-emergency logic that applies to everything else in property, except delay now carries legal interest.
The human point, kept in view
Underneath all the compliance detail sits the reason the law exists. Mould makes people ill, children and asthmatics most of all, and a warm, dry, ventilated home is the baseline of decent housing rather than some premium feature. The happy alignment of 2026 is that the right thing and the smart thing have merged. Glazing that ends condensation also cuts tenants' bills, lifts the EPC, reduces voids and complaints, and protects the asset. We work with landlords and agents across Greater Manchester on exactly this: unit swaps, repairs and full replacements, documented for the file and scheduled around tenancies. The law sets the floor. The physics does the rest.
Frequently asked questions
What is Awaab's Law in simple terms?
It sets legal timescales for landlords to investigate and fix damp, mould and other hazards. Emergencies within 24 hours, significant hazards on fixed investigation and repair deadlines, with findings shared in writing. Social housing came first from October 2025; the private rented sector follows under the Renters' Rights Act.
Does Awaab's Law apply to private landlords in 2026?
The framework is being extended to the private sector under the Renters' Rights Act, so check the current commencement position for your tenancies. In practice, courts and insurers already benchmark against its standards, which means private landlords should operate as if they're in scope now.
Can landlords still blame condensation on tenant lifestyle?
That defence has effectively died. Where cold glazing and poor ventilation make condensation inevitable, the fabric is the cause and it's the landlord's to fix. Normal cooking, washing and breathing aren't tenant misconduct.
Do new windows stop mould in rental properties?
They remove its main engine. Modern Low-E units keep inner surfaces above the dew point, and integrated trickle vents restore background airflow. Paired with working extract fans, glazing upgrades end most recurrent condensation mould at the root.
What should a landlord do when a tenant reports mould?
Acknowledge it straight away, inspect within the statutory window, treat the visible growth, diagnose the cause (glazing, ventilation, leaks), share findings in writing and schedule the fix, documenting every step with dates and photos. The clock and the paper trail are both part of compliance now.
Is fixing mould cheaper than the penalties?
Almost always. A room's worth of replacement sealed units costs a few hundred pounds, set against tribunal awards, rent repayment orders, void periods and reputational damage. Preventing it at portfolio level is cheaper still than any reactive route.
Landlord with a damp file open?
We survey, fix the glazing at the root and hand you a documented paper trail. Unit swaps in days, full replacements scheduled around tenancies, right across Greater Manchester. One call before the clock runs out.
