The Short Answer: It's Complicated
If you're living with damp and mould in your London rental, you're probably wondering whether you can simply walk away from your tenancy. The short answer is that there's no automatic legal right to break your lease because of damp. But that doesn't mean you're without options.
The law gives tenants significant protections when landlords fail to maintain properties. Understanding these rights, and knowing when and how to use them, can help you either fix the problem or exit the tenancy without losing money.
This guide explains your legal position, the steps you should take, and how the landscape is changing with new legislation coming into force.
What the Law Says About Damp and Mould
UK law is clear that landlords must provide homes that are safe and fit to live in. Several pieces of legislation protect tenants from substandard housing conditions.
Landlord and Tenant Act 1985
Section 11 of this Act requires landlords to keep in repair the structure and exterior of the property, including drains, gutters, and external pipes. They must also maintain installations for water, gas, electricity, heating, and sanitation.
If damp is caused by a leaking roof, failed pointing, broken gutters, or defective damp proofing, these are structural issues that fall squarely within the landlord's legal responsibility.
Homes (Fitness for Human Habitation) Act 2018
This Act requires landlords to ensure properties are fit for human habitation throughout the tenancy. A property might be unfit if conditions seriously affect a tenant's health or put them at risk of harm.
Severe damp and mould that poses a health risk can make a property legally uninhabitable. The Act covers factors including freedom from damp, adequate ventilation, and absence of conditions prejudicial to health.
Housing Health and Safety Rating System (HHSRS)
Local authorities use the HHSRS to assess hazards in residential properties. Damp and mould growth is a defined hazard. If an environmental health officer identifies a serious Category 1 hazard, the council is required to take enforcement action against the landlord.
Awaab's Law
Named after Awaab Ishak, a two-year-old who died in 2020 from respiratory problems caused by prolonged mould exposure in his family's social housing, this law sets strict timeframes for social landlords to address damp and mould hazards.
From October 2025, social landlords must investigate hazards within 14 days, provide a written summary within 3 days, and begin repairs within 7 days for significant hazards (or 24 hours for emergencies).
The Renters' Rights Act 2025 will extend Awaab's Law to private landlords, though the exact implementation date is expected around 2030.
Can You Just Leave?
Walking out of a tenancy because of damp is risky. Simply leaving without following proper procedures can result in:
Losing your deposit
Remaining liable for rent until the end of the fixed term
Facing a money claim from your landlord
Being marked as having made yourself intentionally homeless (if you need council housing assistance)
No specific legislation gives you an automatic right to end a tenancy early because of damp and mould. However, there are several legitimate routes to exit.
Using a Break Clause
Check your tenancy agreement for a break clause. This allows either party to end the tenancy early by giving notice. If your agreement includes one, you can use it without having to prove anything about the property's condition.
Not all tenancies have break clauses. They're more common in longer fixed terms and must be negotiated before you sign.
Negotiating Surrender
You and your landlord can mutually agree to end the tenancy early. This is called surrender. If your landlord refuses to deal with damp problems, they might prefer to let you leave rather than face formal complaints or legal action.
Get any agreement in writing and ideally as a signed deed. Make sure the agreement confirms you'll receive your deposit back and won't be pursued for remaining rent.
Claiming the Property is Uninhabitable
If the property is genuinely unfit for human habitation, you may have grounds to argue the landlord has breached the tenancy agreement and you're entitled to leave.
This is a high bar. The damp must be severe enough to seriously affect your health or safety. You'll need evidence, and you should seek legal advice before taking this route.
If you leave claiming uninhabitability and your landlord disputes it, you could end up in court fighting over the deposit and unpaid rent.
The Better Approach: Force the Landlord to Act
Rather than walking away and risking financial consequences, the smarter approach is usually to force your landlord to fix the problem, or build a case that protects you if you do need to leave.
Step 1: Report the Problem in Writing
Landlords only become liable for repairs once they know about the problem. Report damp and mould in writing, whether by email, text, or letter. Keep copies of everything.
Describe the problem, its location, and how long it's been present. Mention any health effects you or your household have experienced. Take dated photographs.
Step 2: Give Reasonable Time to Respond
The law requires landlords to act within a reasonable timeframe once notified. What counts as reasonable depends on the severity.
Emergency hazards that pose immediate health risks should be addressed within 24 hours. Less urgent repairs might reasonably take a few weeks. If you've heard nothing after a month, that's generally considered unreasonable.
Step 3: Follow Up and Document
Send follow-up communications if you don't receive a response. Keep a log of all contact, including phone calls (note the date, time, and what was discussed).
If the landlord visits or sends contractors, note what they said and what, if anything, was done.
Step 4: Contact Environmental Health
If your landlord fails to act, contact your local council's environmental health team. They can inspect the property and assess whether the damp poses a health hazard.
If they identify a serious hazard, they can serve an improvement notice requiring the landlord to carry out repairs. They can also prosecute landlords who fail to comply.
Having council involvement on record strengthens your position if you later need to defend leaving the tenancy or make a compensation claim.
Step 5: Seek Legal Advice
If the situation isn't resolved, consider consulting a solicitor who specialises in housing disrepair. Many offer initial consultations free of charge.
A solicitor can advise on the strength of your case, whether you can safely leave the tenancy, and whether you're entitled to compensation.
Protection from Retaliatory Eviction
One reason tenants tolerate poor conditions is fear that complaining will lead to eviction. This fear has been well founded: under Section 21 of the Housing Act 1988, landlords could evict tenants without giving a reason.
Current Protections
Even now, there are some protections against retaliatory eviction. A Section 21 notice can be invalid if served after a tenant has complained about repairs and environmental health has taken enforcement action.
The Renters' Rights Act 2025
From 1 May 2026, Section 21 "no-fault" evictions will be abolished entirely. This is transformative for tenant rights.
Once the Act takes effect, landlords will only be able to evict tenants for specific reasons set out in law, such as rent arrears, antisocial behaviour, or the landlord needing to sell or move into the property. They cannot evict simply because a tenant complained about repairs.
All tenancies will become periodic, meaning they roll from month to month rather than being fixed for a set term. Tenants can leave with two months' notice at any time. Landlords must go to court and prove valid grounds for any eviction.
This means tenants will finally be able to challenge damp and poor conditions without fear of losing their home.
Can You Claim Compensation?
If your landlord has failed to address damp and mould after being notified, you may be entitled to compensation for:
Loss of Amenity
This covers the reduction in your enjoyment of the property. Compensation is typically calculated as a percentage of your rent for the period you lived with the problem. For severe damp affecting multiple rooms, this might be 25% to 50% of rent. Completely uninhabitable properties could theoretically warrant 100%, though this is rare.
Damage to Belongings
If damp has ruined furniture, clothing, bedding, or other possessions, you can claim the replacement value. Keep receipts where possible and document the damage with photographs.
Health Impact
If damp has caused or worsened health problems, you may be able to claim additional compensation for personal injury. Respiratory conditions, allergies, and asthma attacks linked to mould exposure can all form the basis of a claim.
You'll need medical evidence showing the condition and linking it to your housing. The disrepair doesn't have to be the only cause; it can be a contributing factor.
Time Limits
You generally have six years from when the problem started (or when you became aware of it) to bring a housing disrepair claim. For personal injury claims, the limit is three years.
Importantly, you can still claim compensation after you've moved out. So even if you've already left a damp property, you may still be able to pursue the landlord.
Who Is Responsible for Damp?
Not all damp is the landlord's responsibility. Understanding who is liable is crucial before taking action.
Landlord Responsibility
Landlords are responsible for damp caused by:
Structural defects (leaking roofs, failed pointing, cracked walls)
Failed or bridged damp proof course
Defective gutters, downpipes, or drainage
Inadequate ventilation systems they installed
Broken extractor fans
Poor insulation that causes condensation through design flaws
Penetrating damp from external defects
Rising damp from failed damp proofing
Potential Tenant Responsibility
Tenants may be responsible if damp is caused purely by their behaviour:
Blocking ventilation by covering trickle vents
Never opening windows
Drying large amounts of laundry indoors without ventilation
Failing to heat the property at all
However, the government is clear that landlords should not blame "lifestyle" factors without proper investigation. If the property lacks adequate ventilation or heating, that's a design issue the landlord must address.
Many condensation problems that appear to be tenant-caused actually stem from structural issues like inadequate insulation, poorly designed ventilation, or windows that don't open properly. A professional damp survey can establish the true cause.
What Tenants Should Do Now
If you're a London renter dealing with damp, here's your action plan:
Immediate Steps
Report the problem in writing to your landlord. Take photographs and keep copies of all communications. Note any health effects you or your household experience.
If No Response
Contact your local council's environmental health department. Continue documenting the problem and your communications with the landlord.
Protect Yourself
Don't withhold rent as this can lead to eviction and won't help your case. Consider whether you have a break clause you can use. Seek free legal advice from organisations like Shelter or Citizens Advice.
Before Leaving
Don't move out without somewhere permanent to go. Get legal advice before breaking your tenancy agreement. If you negotiate an early exit, get it in writing.
After Leaving
You can still pursue compensation after you've moved out. Gather your evidence and consult a housing disrepair solicitor.
How a Professional Damp Survey Helps
If you're locked in a dispute with your landlord over damp, an independent professional survey can be invaluable.
Establishes the Cause
A surveyor using moisture meters, thermal imaging, and expert knowledge can identify whether damp is caused by structural defects (landlord responsibility) or purely tenant behaviour (tenant responsibility). Most disputes over "lifestyle" vs structural causes can be resolved with proper investigation.
Provides Evidence
A professional report documents the type, extent, and cause of damp. This evidence supports complaints to environmental health, strengthens compensation claims, and can be used in court if necessary.
Demonstrates You Took Reasonable Steps
If you later need to justify leaving the tenancy, having commissioned a professional survey shows you acted responsibly rather than simply walking out.
Identifies Solutions
A good survey doesn't just identify problems; it recommends appropriate remediation. This gives your landlord clear guidance on what needs to be done.
FAQs: Tenants and Damp
Can I withhold rent because of damp?
No. Withholding rent is risky and can lead to eviction proceedings. Continue paying rent while pursuing other remedies such as environmental health complaints and compensation claims.
Can I do the repairs myself and deduct the cost from rent?
Technically, tenants can sometimes do this, but it's complicated and risky. You need to give the landlord written notice and reasonable time to act first. Seek legal advice before attempting this.
How quickly should my landlord respond to reports of damp?
There's no fixed legal timeframe in the private sector (yet). Generally, landlords should acknowledge reports promptly and arrange inspections within a few weeks. Emergency hazards affecting health should be addressed much faster. Awaab's Law will introduce specific timeframes when extended to private landlords.
What if my landlord blames my lifestyle?
Landlords cannot simply dismiss complaints as lifestyle issues without investigation. The Housing Ombudsman has ruled that the "lifestyle" defence is not acceptable. Request a professional damp survey to establish the true cause.
Can I be evicted for complaining about damp?
Currently, there are limited protections against retaliatory eviction, but they're not comprehensive. From 1 May 2026, Section 21 "no-fault" evictions will be abolished, making it much harder for landlords to evict tenants who complain.
What compensation can I get?
Compensation typically ranges from a few hundred to several thousand pounds, depending on severity, duration, and health impact. Awards of 25% to 50% of rent for the affected period are common. Health-related claims and damage to belongings can increase the total significantly.
How long do I have to make a claim?
Six years for housing disrepair claims, three years for personal injury. You can claim after you've moved out.
