Awaab's Law and Private Landlords: Your Damp, Mould and Decent Homes Duties

TL;DR: Awaab's Law sets legally binding deadlines for dealing with dangerous hazards like damp and mould. Since 27 October 2025 it has applied to social landlords only. The Renters' Rights Act gives the government the power to extend it to private landlords, but no start date is confirmed as of 17 July 2026. The part most guides miss: you don't need to wait for that clock to start. Private landlords already owe a legal duty to keep homes free of serious damp and mould under the Homes (Fitness for Human Habitation) Act 2018 — Awaab's Law won't create that duty, it will simply put a deadline on it.

For years, damp and mould was the kind of complaint a busy landlord could let slide down the to-do list behind the gas safety check and the tax return. Awaab's Law changes the tempo. It turns "we'll get to it" into a countable number of working days, and it does so in a niche that is already under more regulatory pressure than any private landlord asked for. This guide sets out what Awaab's Law actually requires, exactly where private landlords stand today, and how to get ahead of the deadlines before they start ticking on your properties.

What is Awaab's Law, and does it apply to private landlords?

Awaab's Law is named after Awaab Ishak, a two-year-old who died in 2020 after prolonged exposure to mould in a social home. It was introduced through the Social Housing (Regulation) Act 2023 and given legal effect by the Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025. According to the government's Awaab's Law guidance for social landlords, it came into force on 27 October 2025 and forces social landlords to deal with emergency hazards, and with damp and mould, inside fixed timeframes rather than at their own pace.

As of 17 July 2026, Awaab's Law does not yet apply to private landlords — but the Renters' Rights Act contains the power to change that. The government's Guide to the Renters' Rights Act confirms the Act "will allow new requirements to be set requiring private rented sector landlords to address hazards, such as damp and mould, within a specified time period," adding that the government "will set out further detail on our plans in due course." In plain terms: the power is on the statute book, the deadlines are coming to the private sector, but the switch has not been flicked and no commencement date has been published.

What are the Awaab's Law timescales for damp and mould?

The confirmed timescales apply to social landlords today, and they are the clearest preview of what private landlords will eventually face. The government's guidance sets a two-track system: a fast track for emergencies, and a defined track for significant damp and mould. Each track starts from the moment the landlord becomes aware of the problem — not from a convenient date in your diary.

These are the social-sector figures set out in the government's timeframes guidance. For a significant damp and mould hazard, the sequence a social landlord must follow looks like this:

1. Investigate within 10 working days. Once you are aware of a potential damp and mould hazard, you have 10 working days to inspect and establish whether there is a genuine hazard and what is causing it.
2. Write to the tenant within 3 working days. Within 3 working days of finishing the investigation, you must give the tenant a written summary of what you found and what you intend to do.
3. Make the home safe within 5 working days. Relevant safety work to make the hazard safe must be done within 5 working days of concluding the investigation, with any longer preventative works begun promptly and, where they cannot start straight away, within 12 weeks.

The reason these deadlines are drawn so tightly for damp and mould is health, not paperwork. The government's guidance on the health risks of damp and mould is explicit that mould can cause serious harm, especially to children and people with respiratory conditions — which is exactly why the law now measures a landlord's response in working days rather than good intentions.

Do private landlords already have to deal with damp and mould?

Yes — and this is the point most Awaab's Law coverage skips over. You do not get a free pass until the regulations reach the private sector. Under the Homes (Fitness for Human Habitation) Act 2018, in force since 20 March 2019, a private landlord in England must keep a let property "fit for human habitation," which the government's guide for landlords confirms means free of hazards — including damp and mould — that are so serious the home is not reasonably suitable to live in.

The one thing that Act does not give you is a stopwatch. The same government guidance notes there is currently no specific timeframe within which damp and mould work must be done, only that landlords should act promptly and treat serious cases as urgent. That single gap — a real duty with no deadline — is precisely the space Awaab's Law is designed to fill. Understanding this reframes the whole debate: the argument is not whether private landlords must tackle damp and mould, because they already must. The only thing changing is how fast, and how measurable, that response has to be.

You already owe your tenants a home free of serious damp and mould. Awaab's Law doesn't add the duty — it adds the deadline.

Worked example: a mould report on a Manchester terrace

Take a landlord with a three-bed terrace in Manchester, let on a standard assured tenancy. In November the tenant emails to say black mould is spreading across the bathroom ceiling and creeping into the back bedroom, and their youngest has a persistent cough.

Under the rules today, this landlord is already exposed. The Fitness for Human Habitation Act duty is live: if the mould makes the home unfit and the landlord drags their feet, the tenant can take them to court for repairs and compensation. But there is no fixed clock, so a landlord who books an inspection "in a couple of weeks" is not automatically in breach of a deadline — only of the general duty to act promptly.

Now run the same email through the Awaab's Law regime that already binds social landlords and is coming to the private sector. The clock starts the moment that email lands. The landlord has 10 working days to investigate, 3 working days after that to put the findings in writing to the tenant, and 5 working days from the end of the investigation to make the hazard safe. The vague "we'll sort it" becomes a documented timeline a court or council can check against a calendar. For a self-managing landlord juggling several properties, the practical lesson is simple: build the fast response now, on the properties you already own, so the deadline is a formality rather than a scramble when it finally lands.

How does the Decent Homes Standard fit in?

Awaab's Law is not the only quality bar heading for the private rented sector. The same Renters' Rights Act applies a Decent Homes Standard to privately rented homes for the first time — a broader baseline covering the overall condition of a property, not just damp and mould. The government's Renters' Rights Act guide states that "applying a DHS to privately rented homes will ensure tenants benefit from homes that are safe and decent," and that it will apply to homes let on assured tenancies and to privately rented supported housing.

As with Awaab's Law, the timing is not yet fixed. The government published a consultation on a reformed Decent Homes Standard on 2 July 2025, which closed on 10 September 2025, but no enforcement date has been set as of 17 July 2026. The sensible read is that Awaab's Law and the Decent Homes Standard are two halves of the same push: one puts deadlines on the worst hazards, the other sets a floor for general condition. If you want the detail on the condition side, our guide to the Decent Homes Standard for private landlords breaks it down, and our existing explainer on Awaab's Law, damp and mould covers the hazard side in more depth.

What happens if you ignore damp and mould?

The enforcement routes already exist, which is why waiting for Awaab's Law before you act is a poor bet. A private tenant can take a landlord to court under the Fitness for Human Habitation Act if the home is unfit, and the court can order repairs and award compensation. Separately, a local authority can inspect under the Housing Health and Safety Rating System and require works where it finds a serious hazard. Once Awaab's Law reaches the private sector, a missed deadline becomes a breach of a term implied into the tenancy — a cleaner, faster route for a tenant to enforce.

The good news is that getting ahead is mostly about process, not cost. A landlord who logs every damp or mould report with a date, inspects quickly, writes to the tenant, and keeps evidence of the fix is already meeting the spirit of Awaab's Law and building the paper trail that protects them.

Frequently Asked Questions

Does Awaab's Law apply to private landlords yet?

No. As of 17 July 2026, Awaab's Law applies only to social landlords in England, where it has been in force since 27 October 2025. The Renters' Rights Act gives the government the power to extend it to the private rented sector, but no start date has been announced.

How quickly will private landlords have to fix damp and mould?

The confirmed social-sector timescales — investigate within 10 working days, write to the tenant within 3 working days, and make the home safe within 5 working days — are the likely template for private landlords. The private-sector timescales will be set by future regulations and could differ, so confirm the current rules before you rely on a specific deadline.

What counts as an emergency hazard under Awaab's Law?

An emergency hazard is one that presents an imminent and significant risk of harm — the government's guidance gives examples such as gas leaks, dangerous electrics, serious water leaks and, in severe cases, extreme damp and mould. Emergency hazards must be investigated and made safe within 24 hours.

What is the difference between Awaab's Law and the Decent Homes Standard?

Awaab's Law puts fixed deadlines on fixing specific dangerous hazards, starting with damp and mould and emergency hazards. The Decent Homes Standard sets a broader minimum condition baseline for the whole property. Both are being extended to the private rented sector by the Renters' Rights Act.

Can a tenant take me to court over damp and mould today?

Yes. Under the Homes (Fitness for Human Habitation) Act 2018, a private tenant in England can already take a landlord to court if the home is unfit because of serious damp and mould. The court can order the landlord to carry out repairs and can award the tenant compensation.
