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