Damp and Mould Housing Disrepair Claims

Damp and mould in a rented home is not just unsightly — it is a serious health hazard and a legal issue. If your landlord has been notified and failed to act, they are in breach of their statutory obligations. You may be entitled to repairs, compensation, and a rent reduction for every month you were forced to live in affected conditions.

What the Law Says

Section 11 of the Landlord and Tenant Act 1985 obliges your landlord to keep the structure and exterior in repair, covering all structural causes of damp. The Homes (Fitness for Human Habitation) Act 2018 specifically lists damp and mould as factors in assessing fitness. The HHSRS classifies damp and mould as a Category 1 hazard when it poses a significant risk to health.

Common Causes

Rising damp — Moisture from the ground rises through walls when the damp proof course fails — a structural defect the landlord must fix.

Penetrating damp — Water entering through cracked walls, a damaged roof, failed gutters, or defective window frames.

Condensation from poor ventilation — Where adequate ventilation or heating is not provided, condensation builds up and mould follows.

Leaking pipes or plumbing — Slow internal leaks can saturate walls and floors for months before becoming visible.

Blocked or damaged gutters — Overflowing gutters saturate external walls and allow water to penetrate to internal surfaces.

Warning Signs to Watch For

Black, green, or white mould patches on walls, ceilings, or around windows
Persistent musty or earthy smell in one or more rooms
Wallpaper bubbling, peeling, or lifting from walls
Tide marks or brown staining on walls or ceilings
Salt deposits or white powder on brickwork or plasterwork
Flooring that feels soft, damp, or spongy underfoot

Landlord Response Timeframes

24-48 hours for widespread black mould affecting multiple rooms or causing acute health symptoms. 14-21 days for significant spreading damp or new mould outbreaks. 28 days for general damp that does not pose an immediate health risk.
