Is my landlord legally required to fix damp and mould?

Yes. Damp and mould caused by a structural defect, inadequate heating or ventilation, or penetrating damp from disrepair can fall within the landlord's repair duty under section 11 of the Landlord and Tenant Act 1985 and the Homes (Fitness for Human Habitation) Act 2018. Those duties already apply now. Awaab's Law is being extended to the private rented sector, but the official detailed timetable for private landlords must be checked carefully.

What should I do first if I find damp or mould?

Report it to your landlord in writing - email, text, or letter - with the date clearly stated and photographs attached. Keep a copy. This creates the written notice that matters for existing repair and fitness duties. Do not rely on a verbal report; you need evidence of when the landlord was notified.

My landlord says the mould is caused by my lifestyle: is that true?

Sometimes condensation mould is linked to tenant behaviour such as insufficient ventilation or drying clothes indoors. But landlords often use this as a blanket excuse when the real cause is inadequate insulation, poor heating, or penetrating damp. An HHSRS inspection by the council's environmental health team can determine the actual cause independently, and where structural factors contribute, the duty to repair falls on the landlord regardless of any tenant behaviour.

How long does my landlord have to fix damp and mould?

There is no single timetable for every case. Existing law usually requires action within a reasonable time once the landlord has notice, and serious health or safety risks justify faster escalation. Awaab's Law is being extended to the private rented sector, but the detailed private-sector timetable must be confirmed from current official guidance rather than assumed.

Can I withhold rent because of damp and mould?

This is risky and not generally advisable without legal advice. Withholding rent can lead to a rent-arrears possession claim even where the underlying repair dispute is valid. The safer route is to keep paying rent, document the issue, put the landlord in breach through formal written reporting, and pursue a housing disrepair claim or environmental health complaint. A disrepair counterclaim can reduce any arrears figure if possession proceedings are brought.

What can I claim if my landlord refuses to fix damp and mould?

You may be able to claim a court order requiring specific repairs; damages for the period of disrepair based on a reduction in the property's rental value plus any personal injury or damage to belongings; and the cost of storage or temporary accommodation if the property became uninhabitable. Many housing disrepair claims settle before trial. Seek advice from Shelter on 0808 800 4444 before bringing a claim.

Damp and mould: your rights as a tenant in England

Direct answer

Landlords already owe repair, fitness, and serious hazard duties in damp and mould cases. Awaab's Law is being extended to the private rented sector, but the detailed private rented sector timetable must be checked carefully against current official guidance.

Your landlord has legal duties to deal with damp and mould wherever repair, fitness, or serious hazard law applies, and those duties are in force now. Awaab's Law is being extended to the private rented sector, but the detailed private-sector timetable must be checked against current official guidance rather than assumed.

The legal framework: three overlapping duties

Damp and mould is covered by three overlapping statutes, each giving you a separate right of action.

Landlord and Tenant Act 1985, section 11 (structural repairs): the landlord must keep the structure and exterior in repair. Penetrating damp from a damaged roof or wall, rising damp from a failed damp-proof course, and damp from a structural defect all fall within this duty once the landlord has notice.
Homes (Fitness for Human Habitation) Act 2018 (habitability): the property must be fit to live in throughout the tenancy. This covers the whole property and does not require a specific structural fault - persistent black mould that makes a room unhealthy can breach the standard even where the cause is disputed.
Awaab's Law, Renters' Rights Act 2025 (PRS extension): being extended to private renting, with the detailed timetable to follow consultation. Until it is formally in force, rely on the repair, fitness, and HHSRS duties that already apply.

Types of damp: structural vs condensation

Landlords often argue mould is caused by the tenant's lifestyle. Sometimes condensation mould is linked to behaviour, but just as often the building itself - inadequate insulation, ventilation, or heating - creates the conditions. An HHSRS inspection assesses the real cause independently, and where structural factors contribute, the repair duty falls on the landlord regardless of tenant behaviour.

Usually the landlord's responsibility: penetrating damp from a damaged roof, chimney, or wall; rising damp from a failed damp-proof course; damp through cracked window frames; leaks behind walls; condensation from broken or missing ventilation; mould from inadequate heating infrastructure.
Where tenant behaviour may be relevant: black mould where warm moist air meets cold surfaces; mould around single-glazed windows without trickle vents; bathrooms without extractor fans where the tenant rarely ventilates; mould in wardrobes against poorly insulated external walls.

Health impact and HHSRS classification

Under the Housing Health and Safety Rating System (HHSRS), damp and mould is a recognised hazard. A council surveyor scores it on the likelihood and severity of harm, and a Category 1 hazard triggers a legal duty on the council to take enforcement action - it has no discretion to ignore it.

Exposure to black mould can cause respiratory infections, worsened asthma, allergic rhinitis, and eye or skin irritation, with children, elderly residents, and those with respiratory conditions most at risk. Where health has been affected, personal-injury damages in a disrepair claim can be significant.

What to do: step-by-step escalation

Build a paper trail from day one - it is what every later route relies on.

Report it in writing immediately (email or text), describing the location and extent, with dated photographs. Keep the sent copy.
Give a deadline matched to the risk: urgent health hazards justify same-day escalation to the council; less urgent damp should still be chased promptly in writing.
Document everything: photograph the mould weekly with the date visible, keep records of related medical appointments and damaged belongings.
Contact your council's environmental health team if the landlord fails to act - they can run a free HHSRS inspection and must serve an improvement notice if a Category 1 hazard is found.
Consider a housing disrepair claim for a repair order plus damages for the period of disrepair; many solicitors take these on a no-win no-fee basis.
Watch for retaliatory eviction: if a notice arrives soon after you complain, keep a clear timeline - the Renters' Rights Act 2025 requires a court to dismiss a possession claim brought in retaliation for exercising a repair right.
