You reported the mould six weeks ago. You sent the photos, you sent the texts. Your landlord said they'd look into it. Nothing happened, and now the black patches on your bathroom ceiling have spread to the bedroom wall. You are not being difficult. Your landlord is in breach of their legal obligations.
Damp and mould in rented homes are not a lifestyle issue. They are a health hazard, and the law treats them as one. Under the Landlord and Tenant Act 1985 and the Homes (Fitness for Human Habitation) Act 2018, your landlord has to keep the property in repair and fit to live in, and serious damp or mould can make it legally unfit. The Housing Act 2004 gives your council the power to inspect and force repairs. The Renters' Rights Act 2025 will strengthen these protections further, but some of those changes are still to come, and the dates matter. This guide is clear about what applies now and what is on the way. Around 1 in 10 privately rented homes in England has damp, so this is a common problem, and many of those tenants have a claim they have not yet made.
This article covers what your landlord is required to do, whether Awaab's Law applies to you, how much you can claim in compensation, and what steps to take if your landlord keeps stalling.
What is your landlord legally required to do about damp and mould?
The legal baseline for landlord obligations on damp and mould comes from two pieces of legislation. The Landlord and Tenant Act 1985 requires landlords to keep the structure and exterior of a property in repair, which includes walls, roofs, windows, and drainage systems. The Housing Act 2004 introduced the Housing Health and Safety Rating System (HHSRS), which classifies damp and mould growth as a Category 1 hazard when it poses a serious risk to occupants' health.
The distinction that trips most tenants up is the question of cause. Landlords are responsible for damp that comes from structural defects. That means rising damp, penetrating damp from a damaged roof or wall, or condensation caused by inadequate ventilation or heating that the landlord controls. If a qualified surveyor determines the mould is caused entirely by a tenant's own behaviour (for example, drying laundry in an unventilated room with no extractor fan), the picture gets more complicated. But in practice, most damp in UK rentals has a structural component. Older properties, poor insulation, broken seals around windows, and blocked gutters are landlord responsibilities, not tenant ones.
The Homes (Fitness for Human Habitation) Act 2018 sits on top of these duties. It requires your home to be fit to live in, and serious damp or mould can make it unfit whether it comes from condensation, rising damp, or a structural fault. The main exception is damage caused solely by your own behaviour. You can enforce this in the county court yourself, without waiting for the council to act first. The Renters' Rights Act 2025 will also bring the Decent Homes Standard to private rentals, but that is a future change, not current law. The government has confirmed it will apply from 2035. Until then, your live protections are the repairing and fitness duties above and your council's HHSRS powers.
Does Awaab's Law cover private renters yet?
Awaab's Law came directly from the death of two-year-old Awaab Ishak in 2020, who died from prolonged exposure to black mould in a social housing flat in Rochdale. The coroner's inquest found the mould was a significant factor in his death. Parliament responded with legislation requiring landlords to act within fixed timescales, rather than whenever they felt like it.
Here is the part that matters for where you live. Awaab's Law is in force for social landlords, in phases from 27 October 2025. A social landlord must investigate an emergency hazard and carry out emergency safety work within 24 hours, investigate significant damp and mould within 10 working days, and complete the safety work within 5 working days of that investigation.
For private landlords, Awaab's Law is not in force yet. The Renters' Rights Act 2025 extends it to private lettings, but the government still has to consult on and make the detailed regulations, and the current expectation is around 2027. So if you rent privately, you cannot yet hold your landlord to those fixed 24-hour or 10-day deadlines.
What you can rely on now is the standard that has always applied to private landlords. Once you report damp in writing, your landlord must put it right within a reasonable time, and what counts as reasonable depends on how serious the hazard is. Black mould spreading across a bedroom is not something a landlord can leave for months. That reasonable period starts running when you report the problem, which is why written, dated reports matter so much. A text, an email, or a WhatsApp message with a timestamp and a photo is evidence. A phone call is not.
How much compensation can a tenant claim for damp and mould?
Compensation for damp and mould disrepair claims typically falls into three categories: general damages for living in a substandard property, special damages for costs you've actually incurred, and in some cases, rent repayment.
General damages are calculated based on how long you lived in the property while it was in disrepair and how severely the condition affected your quality of life. Courts and tribunals look at the proportion of the property affected, how long you were reporting the issue, and whether it affected your health. A bedroom made unusable by mould for six months in a two-bedroom flat could easily produce a general damages award in the range of £2,000 to £5,000, though actual awards vary by case.
Special damages cover out-of-pocket costs you can prove: clothing or furniture damaged by mould, medical expenses linked to respiratory problems caused by the damp, alternative accommodation costs if the property became uninhabitable. Keep receipts.
Rent repayment is a narrower route than tenants often assume. A rent repayment order is not available just because a property is damp. It becomes possible where the landlord has committed a specific offence, for example failing to comply with a council improvement notice or prohibition order for the hazard, or renting out an unlicensed HMO.
Where one of those offences applies, a rent repayment order returns the rent you actually paid while the offence was running, capped at 12 months for offences before 1 May 2026 and 2 years for offences from that date. Because the order only reaches rent paid during the offence period, the 2-year ceiling is not reachable in practice until 2028. This is one reason getting the council involved, and its notice on record, can matter for more than the repair itself.
How to build a disrepair claim your landlord cannot ignore
A disrepair claim lives or dies on evidence. The process is straightforward once you have the right documentation.
First, create a written record of every communication with your landlord about the damp or mould. Screenshots, emails, letters. If you've only spoken on the phone, send a follow-up email summarising the conversation: 'Further to our call today, I am writing to confirm I reported the mould on the bathroom ceiling and bedroom wall.' This creates a paper trail even if the original conversation wasn't written.
Second, photograph the affected areas thoroughly, with timestamps active. Photograph from multiple angles, photograph any personal property damaged, and photograph again every week if the problem worsens. Progression photos are strong evidence of how long the landlord let the condition deteriorate.
Third, get a surveyor or an environmental health officer involved. Your local council's environmental health team can inspect the property for free and issue a formal improvement notice to your landlord if they find a Category 1 hazard. That notice is evidence. It removes any ambiguity about the severity of the problem.
Fourth, send a formal letter before action. This is a letter that states the disrepair, the dates you reported it, your landlord's failure to act, and the compensation you are seeking. Landlords who ignored texts often respond quickly to a formal legal letter citing the Housing Act 2004 and the Landlord and Tenant Act 1985.
Remedy can draft that letter for you. The platform analyses your situation, cites the relevant legislation, and generates a formal letter your landlord will take seriously. You don't need a solicitor for this step, and generating a legal letter to your landlord costs a fraction of what a law firm would charge.
When can you take a damp or mould complaint to court?
A letter before action resolves many landlord disrepair cases without needing to go further. But some landlords still do nothing, or they do just enough work to make the mould disappear temporarily, then walk away before the cause is fixed. If your landlord is in that category, tribunal is the next step.
The county court handles disrepair claims, and the First-tier Tribunal (Property Chamber) handles rent repayment orders. The right route depends on what you're claiming. For general and special damages from disrepair, the county court is where most claims land. For rent repayment orders, it's the tribunal.
This is where preparation matters. A tribunal bundle is the set of documents you submit to support your case: your tenancy agreement, the timeline of communications, photographs, the council's environmental health report if you have one, any medical evidence linking your health issues to the mould. The bundle needs to be organised and clearly labelled.
This is where Remedy can help. You upload and annotate your evidence, the platform tracks your deadlines, and it generates the final submission bundle. If you want a human expert alongside you, that support is available on a no-win-no-fee basis, so it does not depend on being able to pay a solicitor up front.
What tenants get wrong about mould and damp responsibility
Three misconceptions come up repeatedly in disrepair cases, and they cost tenants money.
The first is accepting blame for condensation. Landlords often tell tenants that mould is their fault for 'not ventilating properly.' Sometimes this is true. More often, it's a deflection. If the property lacks adequate extractor fans in the bathroom or kitchen, has windows that don't open, has inadequate heating, or has walls with poor insulation that cause cold surfaces where moisture condenses, the cause is structural. You have a right to request an independent survey to establish the cause. Don't accept a landlord's self-serving opinion on whose fault it is.
The second is waiting too long to report in writing. Tenants often tell landlords verbally, assume the problem is being dealt with, and only start documenting weeks later when nothing has happened. A landlord's reasonable time to put the problem right runs from the date of your written report. Every week you delay that written report is a week you cannot use in your claim.
The third is not knowing you can bring in the council, or sue on fitness. Your local council's environmental health team can inspect under the Housing Health and Safety Rating System and, if the damp is a serious Category 1 hazard, order your landlord to fix it. Separately, the Homes (Fitness for Human Habitation) Act 2018 lets you take your landlord to the county court yourself if the property is unfit to live in. You do not need to go straight to court to force action. Start with your council's environmental health team. Their involvement costs you nothing and strengthens your case.
Damp and mould are not a cosmetic issue to wait out. A private landlord has to repair the hazard within a reasonable time of your written report, and a serious damp or mould problem can make the property legally unfit to live in. Your landlord cannot hide behind vague promises while your health and belongings suffer.
If you have already reported the issue and your landlord hasn't acted, you have a claim. Remedy can tell you what your landlord was required to do, whether they have breached those duties, and what you could be owed, and can draft the formal letter or help you build a tribunal bundle if it comes to that.
