Mould, Fungus or Dampness Claims in the United Kingdom?

Living with damp, black mould or persistent condensation isn’t just miserable—it can damage your health, your belongings, and your finances. If your landlord failed to fix the problem, you may be entitled to compensation. This guide explains how mould compensation claims work, who’s responsible, what you can claim, and typical payout ranges.

You can bring a mould, fungus or dampness claim if your landlord knew about the issue and didn’t fix it within a reasonable time. Compensation can cover pain and suffering (e.g., asthma or dermatitis), damage to belongings, alternative accommodation, and lost earnings. Time limits are strict—3 years for personal injury and 6 years for housing disrepair losses—so act quickly.

Do I have a valid mould compensation claim?

You may have a strong claim if:

• You live in a rented home (private or social) and reported damp or mould, but your landlord failed to repair the cause in a reasonable timeframe.
• The conditions harmed your health (e.g., breathing difficulties, worsened asthma or skin irritation), or damaged your possessions. Government guidance confirms damp and mould pose serious health risks and must be addressed promptly.
• There’s evidence linking the housing conditions to your loss (see the checklist below).

Owner-occupiers can sometimes claim for building defects against developers/contractors, but most mould compensation claims we handle involve tenants in private or social housing.

Who is responsible—landlord, council or housing association?

Landlords must keep rented homes fit for human habitation and address hazards such as damp and mould. In England, “Awaab’s Law” (named after two-year-old Awaab Ishak, who died in 2020 after prolonged exposure to mould) sets strict response timeframes for social landlords from 27 October 2025 (phase-in continues through 2026–27).

Key points in the draft guidance include:

• Emergency damp/mould hazards: investigate within 24 hours and make safe within 24 hours (or provide suitable alternative accommodation).
• Significant hazards: investigate within 10 working days, issue findings within 3 working days, and start remedial works within 5 working days of the investigation ending. Supplementary works must begin as soon as practicable and within 12 weeks.

Although not yet extended to the private sector, wider landlord duties still apply under existing housing law, and MPs’ research briefing sets out options for tenants to escalate damp and mould concerns.

How damp and mould affect health

Damp homes can aggravate or contribute to asthma, chest infections, allergies, and skin conditions. Government and NHS sources note that mould produces spores, allergens, and irritants that can worsen respiratory symptoms—especially in children, pregnant people, and those with existing lung disease.
Certain moulds (e.g., Aspergillus) can cause serious illness in vulnerable people with underlying lung conditions or weakened immunity.

Evidence checklist (what to gather now)

• Photos/videos showing damp patches, black mould growth and condensation.
• Timeline of reports: dates you notified the landlord/agent and their responses.
• Repair records: emails, texts, call logs, repair orders, or inspection notes.
• Medical evidence: GP/consultant letters, prescriptions, inhaler changes, dermatology notes.
• Independent reports (if you have them): EHO/surveyor findings or humidity/temperature logs.
• Receipts: damaged belongings, cleaning, dehumidifiers, replacement bedding or furniture.
• Accommodation costs: temporary hotel stays or additional heating/energy required due to the defect.

What can mould compensation cover?

If your mould compensation claim succeeds, you can recover:

• General damages for pain, suffering and loss of amenity (e.g., breathing problems, dermatitis, anxiety).
• Special damages for financial loss: destroyed/damaged items, medical expenses, travel, lost earnings, and alternative accommodation if your home was temporarily uninhabitable.
• Inconvenience and loss of enjoyment of your home in housing disrepair claims.

How much compensation could I get?

Courts use the Judicial College Guidelines (JCG) as a starting point when valuing injury. Figures below are indicative only and depend on medical evidence and duration/severity.

Injury Type (illustrative)	Typical JCG-Based Brackets*
Respiratory illness (lung disease/asthma) – severe, ongoing disability	£94,470 – £127,530
Respiratory illness – moderate, persistent symptoms	£51,420 – £94,470
Respiratory illness – mild, full/near-full recovery	£29,380 – £51,420
Dermatitis/eczema (hands/skin) – severe, long-lasting	£11,000 – £18,000+
Dermatitis/eczema – moderate	£4,500 – £11,000
Dermatitis/eczema – mild, short-lived	Up to £4,500

*Ranges compiled from recent summaries of the 17th Edition (April 2024) JCG brackets for respiratory disease and skin conditions.

You may also claim property damage (e.g., ruined clothes, bedding, furniture), cleaning costs, and other out-of-pocket losses, supported by receipts.

Time limits (don’t miss your window)

• Personal injury caused by damp/mould: generally 3 years from the date of injury or date of knowledge (when you first realised your symptoms were linked to the conditions). For children, time runs from their 18th birthday.
• Housing disrepair losses (e.g., damaged belongings/amenity): generally 6 years from when the landlord first failed to fix the issue after notice.

Because the clock can run while you’re still chasing repairs, it’s wise to seek help now and protect your position.

Fast-track repairs (where possible)

While your claim progresses, the priority is making your home safe. Current government guidance for landlords emphasises urgent action to address damp and mould and protect health; social landlords now face fixed timeframes under Awaab’s Law.

Practical tips while your claim is investigated

These steps don’t replace repairs, but they can help you manage risk:

• Keep rooms well-ventilated during cooking/bathing; use extractor fans and close doors to trap moisture.
• Avoid drying clothes indoors where possible; if you must, ventilate.
• Maintain steady background heating; sudden temperature swings drive condensation.
• Consider a dehumidifier as an interim measure and record humidity levels to support your evidence.

If symptoms worsen—especially for children, older adults, or anyone with lung disease—speak to your GP.

FAQs about mould, fungus and dampness claims

1. Will Awaab’s Law help private renters?
At present, Awaab’s Law applies to social landlords with staged implementation from 27 October 2025, alongside stronger regulation of the sector. Wider tenancy and housing reforms remain under debate, but private landlords already have legal duties to fix hazards.

2. What if my landlord blames “lifestyle”?
Damp and mould often have structural or ventilation causes. Government guidance warns against tenant-blaming attitudes and requires landlords to investigate and resolve the root cause. Keep reporting issues in writing and gather evidence.

3. Can I claim for stress and loss of enjoyment?
Yes. In housing disrepair claims, you can claim for inconvenience and loss of amenity in addition to injury and financial loss, depending on the facts and evidence.
