Damp and Mould in a Rental Property: Your Legal Duty and Response Deadlines

Damp and Mould in a Rental Property: Your Legal Duty and Response Deadlines

Private landlords in England have no fixed statutory deadline for damp and mould. Awaab's Law applies only to social housing, and its extension to the private sector sits in Phase 3 of the Renters' Rights Act roadmap with no date set. The duty to act comes from section 9A of the Landlord and Tenant Act 1985.

This article is for general information purposes only and does not constitute legal advice. Landlords should seek independent legal advice for their specific circumstances. It describes the position in England.

Does Awaab's Law apply to private landlords?

No, and a considerable amount of published content says otherwise.

Awaab's Law is the Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025, made under the Social Housing (Regulation) Act 2023. It came into force for the social rented sector on 27 October 2025. The MHCLG guidance is explicit that it applies to social housing occupied under a tenancy and let by a registered provider.

The Renters' Rights Act 2025 contains the power to extend it to the private rented sector. The government's implementation roadmap places that in Phase 3, and states that the timescales will be subject to consultation. No consultation outcome has been published and no commencement date has been announced. Shelter has suggested 2027 as the earliest plausible date; the government has not committed to one.

Landlords should treat any source claiming Awaab's Law binds private landlords from 1 May 2026 as wrong.Several currently do. Commencement dates can move, so the position is worth checking against the roadmap before relying on it either way.

What actually applies right now

Four routes, and none of them carries a fixed number of days.

The fitness route matters most and is the most commonly overlooked. Section 9A implies a term into the tenancy that the dwelling is fit for human habitation, and fitness is assessed by reference to the HHSRS hazards, which include damp and mould growth. Unlike section 11, it does not require the problem to be a matter of disrepair. A property that is structurally sound but so poorly ventilated or insulated that mould is inevitable can be unfit without anything being broken.

The remedy is a claim by the tenant for an order requiring the works and for damages. There is no council penalty attached to section 9A and no prescribed timescale, which is precisely why the absence of a deadline is not the reassurance it sounds like.

The social sector timescales, and why they matter to you

Even though these do not yet bind private landlords, they are worth knowing for two reasons: they are the strong signal for what Phase 3 will look like, and courts assessing what was reasonable are unlikely to ignore a published government standard.

The guidance treats the day the landlord becomes aware as day zero, with day one running from the following working day. Its examples of an emergency hazard include prevalent damp or mould having a material impact on a tenant's health, and it treats a report mentioning a pregnancy, a child's asthma, or respiratory symptoms as capable of pushing damp into the 24 hour category.

A private landlord adopting these timescales voluntarily is not complying with Awaab's Law, because it does not apply. They are building a record that answers the question a court will actually ask, which is whether they acted within a reasonable time.

The "lifestyle" problem

The most common landlord response to a mould report is that it is caused by the tenant drying washing indoors and not opening windows. The MHCLG guidance addresses this directly in the social context and the reasoning transfers.

It states that it is unacceptable for landlords to assume the cause of a hazard is the tenant's lifestyle, and that everyday activities such as cooking, bathing, washing and drying laundry unavoidably produce indoor moisture. Those activities are unlikely to constitute a breach of contract by the tenant and should not be a reason to take no action.

The legal point underneath is about deficiency. Where mould results from an absence of adequate ventilation or insulation, the guidance treats that as a structural deficiency the landlord must address, giving installation of mechanical ventilation or effective insulation as examples. Condensation produced by ordinary occupation in a property with no extractor fan is a ventilation problem, not a tenant problem.

Tenant conduct is not irrelevant. Deliberately blocking ventilation fans is given as an example of conduct that takes a hazard outside the regime. The distinction is between ordinary living and deliberate interference, and a landlord asserting the latter needs evidence of it. Our article on telling condensation from rising and penetrating damp covers the diagnostic side.

What a council can actually do

This is where the enforceable exposure sits for private landlords today.

A local housing authority assessing a property under the HHSRS can rate damp and mould growth as a category 1 or category 2 hazard. For a category 1 hazard the authority has a duty to take enforcement action, and the usual route is an improvement notice under section 11 of the Housing Act 2004. Failure to comply with an improvement notice is an offence under section 30, carrying a civil penalty of up to £40,000 with a published starting point of £25,000, or prosecution.

Two further points. The Renters' Rights Act 2025 introduced a financial penalty route for category 1 hazards themselves rather than only for notice breaches, and authorities now hold significantly wider investigatory powers, including the ability to require documents and to enter business premises. Our articles on the civil penalties framework and how councils find non-compliant landlords cover both.

The tenant route is separate and increasingly used. A disrepair counterclaim in possession proceedings reduces the arrears figure, and where that takes the net arrears below the three month threshold, Ground 8 collapses entirely.

What a defensible response looks like

In the absence of a statutory deadline, the standard is reasonableness, and reasonableness is demonstrated by a documented sequence rather than by an outcome.

Log the report on the day it arrives, with the date, who reported it, what they said, and any health information they volunteered. Health information changes the urgency assessment and it is the detail most often absent from a landlord's file.

Respond in writing within a few days, confirming what you will do and when. Inspect promptly, in person unless photographs genuinely resolve the question, giving the 24 hours' written notice that section 11(6) of the Landlord and Tenant Act 1985 requires. Where the cause is not obvious, instruct a survey rather than guessing.

Deal with the immediate hazard and the underlying cause as two separate tasks. A mould wash removes the visible problem; it does not address a failed damp proof course or a missing extractor fan, and a tenant whose mould returns in six weeks has a stronger claim than one whose landlord did nothing.

Keep the tenant updated in writing throughout, including when things slip.

How a tenant enforces this

Three routes, and they run independently of each other.

A claim under section 9A. The tenant applies to the county court for an order requiring the works and for damages. Damages in disrepair cases are commonly assessed as a proportion of the rent for the period the property was unfit, with a separate element for damage to belongings and for distress and inconvenience. There is no cap, and the period runs from when the landlord had notice.

A complaint to the local housing authority. This is free to the tenant and is the route most likely to produce enforcement. The authority inspects, rates the hazard, and where it finds a category 1 hazard has a duty to act.

A statutory nuisance prosecution under section 82 of the Environmental Protection Act 1990. The tenant brings this directly in the magistrates' court without involving the council. Premises in a state prejudicial to health can constitute a statutory nuisance, and severe mould has been treated as capable of meeting that test. The court can order works, impose a fine, and award compensation and costs.

The Pre-Action Protocol for Housing Conditions Claims sits in front of the first route. A landlord receiving a letter of claim under it should treat that as notice of the defect if they did not have it already, and respond within the Protocol timescales rather than waiting for proceedings.

What is coming, and when

Two Phase 3 measures will change the position, and the timing is further out than most commentary suggests.

Awaab's Law for the PRS. Subject to consultation, with no date announced. The social sector phasing runs damp, mould and emergency hazards first, then a wider set of hazards in 2026, then all remaining HHSRS hazards apart from overcrowding in 2027. The private version is expected to follow a similar staged pattern, but the scope and order will be set by regulations that do not yet exist.

The Decent Homes Standard for the PRS. The government's New Decent Homes Standard policy statement indicates application to private rented homes from 2035. That is a decade away, and articles describing it as imminent are not reflecting the published position.

Both are worth preparing for and neither is a current obligation. Landlords are advised to check the roadmap directly rather than rely on secondary summaries, since these are exactly the dates that move.

Damp claims are decided on what the landlord did and when, and the file is usually assembled long after memory has gone. LLCR's Property Issue Log records a tenant report with its date, the actions taken in response, and the evidence, so the sequence exists as a record.
