Mould and Damp in Rental Properties - Your Rights

Complete guide to landlord responsibility for mould and damp, including Awaab's Law reforms, HHSRS Category 1 hazards, local authority enforcement, and compensation claims.

Quick Answer

Your landlord is responsible for mould and damp caused by structural defects (roof leaks, rising damp, condensation issues in poorly maintained properties). Awaab's Law (April 2024) requires landlords to fix Category 1 hazards within strict deadlines (14-28 days). Local authority Environmental Health can force repairs. You can claim rent reduction, damages for health impact, and compensation for breach of s.11 of the Landlord and Tenant Act 1985. You cannot be evicted for reporting mould (protected by Deregulation Act 2015 s.33).

How to Address Mould and Damp

1

Document the Issue

Take photos and video of all affected areas (date-stamped). Note onset date, pattern (where it appears), and whether it follows structural defects (roof, pipes, external walls). If you have health symptoms (respiratory, asthma flare-ups), document these with dates. Keep all communications with the landlord in writing.

2

Report to Local Authority

Contact your local authority's Environmental Health team. Report that the property has structural damp/mould (not condensation from your use). They will inspect and assess under HHSRS. If Category 1 hazard, they issue an enforcement notice giving the landlord 14-28 days to remedy. They monitor compliance and can prosecute if ignored.

3

Claim at Court for Damages

Sue for breach of s.11 and s.9 Homes (Fitness for Human Habitation) Act 2018. Claim rent reduction proportionate to uninhabitability period, damages for health impact (GP visits, medication), inconvenience, and psychological impact. Include the authority's inspection report as evidence. Courts award £100-£500+ per month for serious mould cases.

What the Law Says

Awaab's Law (2024) - Housing (Fitness for Human Habitation and Liability for Housing Standards) Act 2022
Named after Awaab Ishak (4-year-old who died due to mould exposure). Landlords must fix Category 1 hazards (including mould and damp) within 14 days of local authority notification, or 28 days if the landlord requests extension and is progressing repairs. Failure to comply can result in prosecution, unlimited fines, and criminal liability. Landlords can no longer delay indefinitely on serious health hazards.
Housing Health and Safety Rating System (HHSRS) - Environmental Health Act 1990
Local authorities assess properties for hazards. Pervasive damp causing mould is a Category 1 hazard (serious risk to health). HHSRS scoring: properties scoring above 200 points = Category 1 hazard trigger automatic enforcement. Mould affecting multiple rooms is typically Category 1. Category 1 requires enforcement within 28 days of notice served on landlord.
Landlord and Tenant Act 1985 s.11: Implied Repairing Covenant
Landlord must keep structure, roof, and outgoings (including ventilation) in repair. Structural damp (from roof/external walls/ground) is the landlord's liability. Tenant can claim breach if structural repair is needed. Condensation from tenant's daily living (not ventilating/drying) may be shared liability, but poor ventilation is landlord's structural fault.
Homes (Fitness for Human Habitation) Act 2018 s.9
Dwelling must be free from significant damp and mould that poses risk to health. Breach entitles tenant to sue for damages and specific performance (court-ordered repairs). No time limit on bringing claims. Damages include rent reduction, health impacts, inconvenience, and costs incurred. Court can issue orders requiring completion within a deadline.
Deregulation Act 2015 s.33: Retaliatory Evictions Protection
You cannot be evicted for reporting mould/damp to the landlord or local authority. Section 21 notice issued within 6 months of reporting is automatically invalid and must be dismissed by court. This protection applies even if the property is small or outside Housing Act 1988 scope.

Common Mould and Damp Situations

Roof Leak Causing Mould

Water enters from roof during rain; mould spreads in affected rooms. This is clearly landlord's responsibility (s.11 - landlord maintains roof). Report to Environmental Health (Category 1 hazard). Demand repair in writing. If not done within 14 days, authority issues enforcement. Claim rent reduction for the period and damages for health impact.

Rising Damp from Ground

Damp creeps up external walls; mould forms on lower walls. This is structural and the landlord's duty under s.11. Report to Environmental Health. Landlord must install/repair damp proof course (structural work). This triggers Awaab's Law 14-28 day deadline. Claim rent reduction and damages for health issues caused by prolonged damp exposure.

Mould Caused by Poor Ventilation

Ventilation is inadequate (no extractor fans, broken windows). Mould develops. This is partly structural (landlord's duty to provide adequate fittings) and partly tenant use (ventilation from daily living). If property design causes the issue (no windows, no vents), it's the landlord's fault (breach of HHSRS). Claim if landlord refuses to improve ventilation/install extractors.

Condensation Mould on Windows

Mould only on windows due to condensation from showering/cooking. This is usually tenant responsibility (ventilation needed). However, if windows are defective (broken seals, poor insulation) or ventilation is structurally inadequate, landlord is liable. Clarify with Environmental Health whether this is structural. If structural, claim rent reduction and damages.

Persistent Mould After Reported Multiple Times

You've reported to landlord 3+ times; mould returns within weeks. This indicates structural failure. Report to Environmental Health. Await inspection and enforcement notice. If mould continues after authority intervention, sue for ongoing breach. You may be able to claim the property is uninhabitable and break the tenancy early.

Health Impact from Mould (Asthma, Respiratory)

You develop or worsen asthma, chest infections, or allergies due to mould. Report to GP and get medical records. Report to Environmental Health and local authority. Sue for damages including medical costs, medication, and health impact. Courts award higher damages when mould directly impacts tenant health (documented by GP/medical records).

Frequently Asked Questions

What is Awaab's Law and how does it help me? +
Awaab's Law (named after Awaab Ishak, 4, who died from mould-related illness) requires landlords to fix Category 1 hazards (serious health risks including mould/damp) within 14 days of local authority notice, or 28 days if requesting extension and progressing. Failure is a criminal offence with unlimited fines. This gives you a faster enforcement route - once local authority confirms Category 1, the landlord has strict legal deadlines or faces prosecution.
How does local authority Environmental Health enforce mould removal? +
You report the mould. They inspect and assess under HHSRS. If Category 1 hazard, they issue a statutory enforcement notice requiring landlord to fix within 14-28 days. If landlord ignores it, the authority can carry out works themselves and recover costs from the landlord. They can also prosecute for wilful failure to comply, leading to fines and, in severe cases, criminal liability. This is free for you.
Can I claim compensation for mould-related health issues? +
Yes. Sue for breach of s.11 and the Homes (Fitness for Human Habitation) Act 2018. If you have medical evidence that mould caused or worsened health (GP referrals, prescriptions, hospital visits), you can claim damages for: medical costs, medication, inconvenience, psychological impact, and rent reduction for the period the property was uninhabitable. Evidence: GP records, prescription receipts, photos, Environmental Health report.
Will reporting mould get me evicted? +
No. Deregulation Act 2015 s.33 protects you. You cannot be evicted for reporting mould to the landlord, local authority, or Environmental Health. If the landlord serves section 21 notice within 6 months of you reporting, that notice is automatically invalid and the court must dismiss any eviction claim. You are fully protected; report without fear.
What is the difference between Category 1 and Category 2 hazards? +
Category 1 = serious risk to health (mould affecting multiple rooms, severe damp, uninhabitable conditions). Triggers automatic enforcement within 14-28 days under Awaab's Law. Category 2 = moderate risk (limited mould, some damp, but property still habitable). Category 2 does not trigger automatic enforcement but authority can issue guidance to landlord. If in doubt, Environmental Health assesses - pervasive mould is usually Category 1.
Can I break my tenancy early due to mould? +
If mould makes the property uninhabitable (severe structural damp, health risk), you may have grounds to break the tenancy for breach of covenant (s.11, Homes Act 2018). Consult advice first - you'll need strong evidence (Environmental Health report, GP records). Breaking tenancy without legal grounds can trigger eviction. Better to claim damages and rent reduction at court while seeking repairs through local authority enforcement.
