Is your landlord responsible for mould in your flat?
Direct answer
Your landlord is responsible for mould when it is caused by disrepair, damp, leaks, inadequate heating, poor insulation, defective ventilation, or any condition that makes the home unfit for human habitation. The landlord cannot simply blame your lifestyle without investigating the building and ventilation first. You should report the mould in writing, photograph it, explain any health impact, and ask for inspection and remedial works. If the landlord does not act, the council can inspect and enforce.
What the law says
Section 11 of the Landlord and Tenant Act 1985 requires the landlord to repair the structure and exterior and the installations for heating, water, and sanitation. Mould caused by leaking roofs, defective gutters, penetrating damp, rising damp, defective windows, failed extractor fans, or heating failures is therefore the landlord's repair responsibility. Section 9A of the same Act requires the home to be fit for human habitation throughout the tenancy.
The Homes (Fitness for Human Habitation) Act 2018 made the fitness duty enforceable by tenants. Damp and mould are also hazards under the Housing Health and Safety Rating System in Part 1 of the Housing Act 2004. The council can inspect and require action where mould creates a health risk. Where Awaab's Law timescales apply, the landlord must investigate damp and mould within the set deadline and begin remedial action within the required period.
Step-by-step: what to do
1. Photograph the mould close up and from the whole room. Add dates and repeat photos after cleaning or after rain.
2. Report it in writing to the landlord or agent. Describe where it is, when it appeared, and whether there are leaks, cold walls, condensation, broken fans, or heating problems.
3. Ask for an inspection and written plan, not just advice to open windows. The landlord must investigate the cause.
4. Keep health evidence if anyone has asthma, breathing problems, skin irritation, or sleep disruption. Ask your GP to record symptoms.
5. If the landlord does not act, complain to Environmental Health and ask for a Housing Act 2004 inspection.
Common mistakes to avoid
Do not accept a blanket statement that mould is your fault. The landlord must look at the property condition, heating, insulation, and ventilation. Do not rely only on cleaning products: cleaning removes visible mould but does not fix the underlying cause. Do not delay reporting because mould often worsens quickly and the landlord will argue they had no notice. Do not throw away damaged belongings before photographing them.
- Do not let the landlord treat repainting as the only remedy.
- Do not ignore broken extractor fans or heating faults.
- Do not clean before taking dated photos.
- Do not wait for winter to end before escalating health risks.

Common questions
- Is your landlord responsible for mould in your flat?
- Your landlord is responsible for mould when it is caused by disrepair, damp, leaks, inadequate heating, poor insulation, defective ventilation, or any condition that makes the home unfit for human habitation. The landlord cannot simply blame your lifestyle without investigating the building and ventilation first. You should report the mould in writing, photograph it, explain any health impact, and ask for inspection and remedial works. If the landlord does not act, the council can inspect and enforce.
- Can the landlord blame me for mould?
- The landlord can raise tenant behaviour only after investigating the building, ventilation, heating, leaks, insulation, and repair issues. A bare accusation that you caused mould is not enough.
- Does the landlord have to remove mould?
- Yes, when mould is caused by disrepair or makes the home unfit. The landlord must deal with the underlying cause, not just wash or paint over the visible mould.
- Can Environmental Health help with mould?
- Yes. The council can inspect under Part 1 of the Housing Act 2004 and require the landlord to deal with damp and mould hazards.
- Can I claim compensation for mould?
- Yes. A claim can cover loss of amenity, damaged belongings, extra costs, and health impact if the landlord breached section 11 or the fitness duty.
