Mould in Your Rented Home: Your Rights and Your Landlord's Obligations

Damp and mould in a rented property is not just unpleasant — it's a health hazard your landlord is legally required to address. Here's what UK law says and what you can do.

fairead Team16 February 2026

Damp and mould is one of the most common problems in the private rented sector — and one of the most dangerous. Prolonged exposure to mould spores has been linked to respiratory conditions, worsening asthma, and, in the most severe cases, fatal illness.

Following the death of two-year-old Awaab Ishak from a mould-related respiratory condition in a social housing property, the law has tightened significantly. Here's what you're entitled to and what your landlord must do.

Your Landlord's Legal Duty to Repair

Under Section 11 of the Landlord and Tenant Act 1985, your landlord has a statutory duty to keep the structure and exterior of your property in repair — including the roof, walls, windows, and drainage. Damp that results from structural failure (a leaking roof, rising damp, failed cavity wall insulation, defective guttering) falls squarely within this duty.

This obligation cannot be removed by contract. Any clause in a tenancy agreement that attempts to make you responsible for structural repairs is unenforceable.

In addition, the Housing Health and Safety Rating System (HHSRS) — enforced by local councils — classifies damp and mould growth as a potential Category 1 hazard, meaning a serious and immediate risk to health. A local authority can serve an Improvement Notice on your landlord, requiring them to fix the problem within a set period.

Awaab's Law: What It Means for Private Renters

Awaab's Law was originally introduced for the social housing sector under the Social Housing (Regulation) Act 2023. Following the public inquiry into Awaab Ishak's death, the Government extended these protections to the private rented sector under the Renters' Rights Act 2025.

Under Awaab's Law as it applies to private landlords, your landlord must:

  • Investigate any reported damp or mould hazard within 14 days of notification
  • Begin emergency repairs within 24 hours if the hazard poses an immediate risk to health
  • Complete all repairs within a prescribed timeframe depending on severity
  • Provide written confirmation of what they plan to do and when

Failure to comply exposes your landlord to enforcement action and potential compensation claims.

"Lifestyle Condensation" — The Common Landlord Excuse

Landlords frequently blame tenants for damp and mould, citing "lifestyle condensation" — the idea that the tenant is generating too much moisture by cooking, bathing, or drying laundry indoors.

This excuse has limits. While tenants do have a duty not to act in a way that causes damage, courts and adjudicators have become increasingly sceptical of blanket condensation claims, particularly where:

  • The property has poor ventilation, inadequate heating, or cold walls (all structural issues)
  • The problem affects rooms not typically associated with moisture generation (bedrooms, living rooms)
  • The problem persists despite the tenant's reasonable efforts

If your landlord claims your lifestyle is the cause, you are entitled to ask for a damp survey from an independent specialist. A council Environmental Health Officer can also inspect the property and make their own assessment.

How to Report the Problem Correctly

How you report damp and mould matters — both for legal purposes and for preserving your rights.

Step 1: Notify in writing Email your landlord or letting agent, describing the location and extent of the mould, attaching photos with timestamps. Keep a copy of everything.

Step 2: Follow up if nothing happens If your landlord doesn't respond or fails to act within a reasonable time (or within the Awaab's Law timeframes where applicable), send a formal follow-up letter setting out the issue and the legal obligations.

Step 3: Contact your local council If your landlord ignores you, contact the Environmental Health department of your local council. They have the power to inspect the property and serve notices. This is free and you do not need a solicitor.

Step 4: Withhold rent? Be careful Withholding rent is risky and generally not advised. Even if your landlord is in breach of their repair obligations, withholding rent can lead to rent arrears proceedings against you. The correct route is through council enforcement or the courts — not unilateral rent withholding.

Can You Claim Compensation?

Yes. If your landlord has failed to repair a damp or mould problem and you've suffered loss as a result — damage to your belongings, health effects, or having to live in degraded conditions — you may have a claim for damages.

Claims can be made:

  • Through the small claims court (for amounts under £10,000) — straightforward and doesn't require a solicitor
  • Via the Property Ombudsman or a redress scheme if the property is managed by a letting agent
  • Through a no-win no-fee housing disrepair solicitor for more serious cases

The measure of compensation typically includes: reduction in the rental value of the property for the period of disrepair, plus any quantifiable out-of-pocket losses.

What If You Have Mould-Related Health Problems?

If you or a family member — particularly a child — has suffered health consequences linked to mould in your rented property, you may have a personal injury claim in addition to a disrepair claim. Specialist housing solicitors handle these cases, many on a no-win no-fee basis.

Keep records: GP visits, prescriptions, correspondence linking the health issues to your living conditions, and any written advice from a doctor connecting the conditions to damp exposure.

Protecting Yourself as a Tenant

  • Report any damp or mould immediately and in writing — don't wait for it to get worse
  • Take dated photographs of affected areas
  • Keep your property reasonably ventilated (open windows, use extractor fans) — this protects you from a lifestyle condensation counter-claim
  • Do not attempt to paint over mould yourself without the landlord's knowledge — this could be used against you and masks the underlying problem
