Compensation for damp and mould — what tenants can realistically claim

If your home has been affected by damp and mould and your landlord has failed to put it right, you may be entitled to compensation. The amounts vary widely. The Housing Ombudsman has published decisions ranging from a few hundred pounds to several thousand pounds in the most serious cases. This page sets out what you can claim for, how compensation is actually calculated, the five routes available to you, and where the £19.99 Tenant Action Pack fits in.

Realistic, not legal advice. Anchored in published Housing Ombudsman decisions and current statutory timescales.

What you can claim for

There are three distinct categories of compensation, and most successful claims include elements of more than one:

Loss of amenity (sometimes called "rent refund")

The Housing Ombudsman uses the rent you pay as a yardstick for the loss of enjoyment of your home. If part of the home has been unusable, an award equivalent to a percentage of the rent over the period of failure is common. The Ombudsman is explicit that this is not a rent rebate — it's a basis for considering the loss of enjoyment.

Distress and inconvenience

Compensation reflects the impact on you: time and trouble, stress, loss of confidence, disruption to family life. This sits alongside any loss-of-amenity component, not instead of it. The Ombudsman's compensation guidance treats this as a distinct element of an award (see “How the Housing Ombudsman assesses compensation” below).

Special damages — out-of-pocket costs and belongings

Money you actually spent because of the damp and mould: ruined clothes or furniture, prescriptions, extra laundry, dehumidifier hire, alternative accommodation, travel to GP appointments. The Housing Ombudsman has limited jurisdiction over belongings claims and will often direct you to your landlord's insurer for those. Insurance is a separate, parallel route — see "The five routes to compensation" below (Route 1).

How much is awarded in practice

Compensation for damp and mould varies widely. It depends on how serious the hazard was, how long it went unresolved, the impact on the household, and how the landlord handled the complaint. The Housing Ombudsman publishes anonymised findings in its regular “Learning from Severe Maladministration” reports, including a report focused on damp and mould published in October 2024. Because every case turns on its own facts, we do not quote individual case awards. For an illustrative estimate based on your own circumstances, use our compensation calculator.

How the Housing Ombudsman assesses compensation

Since 1 April 2026 the Housing Ombudsman applies its updated guidance, “A New Era for Housing Compensation: Clearer Standards, Fairer Outcomes” (published 3 February 2026). This moved the Ombudsman away from broad principles toward clearer, more structured standards — including some defined sums for specific losses — so that both Ombudsman-ordered remedies and landlords' own offers are assessed more consistently. The amount awarded in any individual case still depends on how serious the hazard was, how long it went unresolved, and the impact on the household.

How compensation is actually calculated

Rent percentage as a loss-of-amenity proxy

The percentages below are an illustrative way of approximating loss of use — consistent with the Ombudsman basing loss-of-use compensation on a proportion of the rent — not the Ombudsman's official figures or a guaranteed rate. When part of the home has been unusable or the conditions have meaningfully reduced enjoyment of the home, the Ombudsman commonly awards a percentage of the rent charged over the period of failure. In the published October 2024 cases, percentages ranged from around 15% (significant impact but rooms partially usable) up to 50% (a full family decant). 20% to 30% is common where rooms became uninhabitable for extended periods. The Ombudsman is explicit: this is a basis for considering loss of enjoyment, not a rent rebate.

Distress and inconvenience on top

An additional component for distress, inconvenience, time and trouble usually sits alongside the loss-of-amenity component. In the published cases, this element tends to fall within the lower three bands (£50–£1,000 per finding). Households with young children, mental health conditions, or disabilities tend to see higher D&I components, reflecting the greater impact.

Special damages for actual costs

Out-of-pocket costs are added in addition: prescriptions, dehumidifier hire, extra laundry, alternative accommodation, travel to medical appointments, ruined belongings. Where the cost is for damaged belongings, the Housing Ombudsman has limited jurisdiction and may direct you to your landlord's buildings or contents insurer. This is not a tactical retreat — it's the correct structural route. But where the insurer has already considered the claim, the Ombudsman will not reconsider it.

Aggravating factors that strengthen a claim

The Ombudsman's Guidance lists factors that tend to increase the award: presence of a mental health condition in the household, young children, disability, dependents with disability, previous history of mishandling by the same landlord. Document these clearly in any complaint.

Mitigating factors that reduce or remove a claim

The Guidance is also explicit about resident behaviour that weakens a claim: failure to communicate clearly with the landlord, failure to bring matters to the landlord's attention within a reasonable timeframe, refusing reasonable help, refusing the landlord access for inspection, or pursuing the complaint in an unreasonable or excessive way. Evidence is not enough on its own — engagement matters.

A worked example

This is an illustrative example, not a real case. Actual outcomes vary widely depending on rent level, duration, rooms affected, and household circumstances. Real published cases range from a few hundred pounds to several thousand pounds in the most serious cases.

A social-housing tenant reports damp and mould to her landlord. Two bedrooms are affected. Her ten-year-old has mild asthma. The landlord inspects at month four, recommends works, and then nothing happens for fourteen more months. The tenant continues to chase. Rent is £550 per month. The tenant goes through the landlord's complaints process; the landlord offers £400. The tenant escalates to the Housing Ombudsman.

On the published bands, the Ombudsman might consider:

• Loss of amenity: Two bedrooms partially affected over eighteen months. At 20% of rent — a common figure where rooms were significantly compromised but not fully uninhabitable — that is around £1,980.
• Distress and inconvenience:Mid-range, factoring in the child's asthma and the eighteen months of stress. Perhaps £400–£800.
• Special damages:Dehumidifier hire of £150, ruined sofa of £400, extra laundry of £100, prescriptions of £30. Note the £400 sofa might go via the landlord's contents insurer rather than the Ombudsman — but the other £280 of out-of-pocket costs typically sits within an Ombudsman award.

An award in the £2,700 to £3,500 range would be plausible in this illustrative case. The landlord's initial £400 offer is well short and likely to be raised on Ombudsman determination. Real outcomes depend entirely on the specific facts.

The five routes to compensation

There is no single route to compensation for damp and mould. The right route depends on what you are claiming for, how serious the conditions are, and whether you are in social or private rented housing. Most cases use more than one route. The five are:

Route 1 — Your landlord's buildings or contents insurer

If your belongings have been damaged by damp, mould, or a leak, the appropriate first step is often a claim against the landlord's buildings insurance (where the damage relates to the building) or your own contents insurance (where it relates to your possessions). The Housing Ombudsman has limited jurisdiction over insurers; where the insurer has considered a claim, the Ombudsman will not generally reconsider the financial element. Insurance is a parallel route, not a substitute for the others below.

Route 2 — The landlord's internal complaint procedure

The Housing Ombudsman's Complaint Handling Code 2024 is statutory from 1 April 2024. It sets out a mandatory two-stage process:

• Stage 1: The landlord must acknowledge your complaint within 5 working days, and issue a full response within 10 working days of that acknowledgement. They may extend by up to 10 further working days for good reason.
• Stage 2: If you escalate, the landlord must acknowledge the escalation within 5 working days, and issue a final response within 20 working days of that acknowledgement. They may extend by up to 20 further working days for good reason.

In practice the full procedure runs around eight calendar weeks at standard pace, up to around fourteen weeks with the maximum permitted extensions. You must usually file the complaint within twelve months of the issue occurring or your becoming aware of it. The complaints process is required before you can escalate to the Housing Ombudsman, except in limited circumstances.

Route 3 — The Housing Ombudsman

If you remain dissatisfied after the landlord's stage 2 final response, you can escalate to the Housing Ombudsman. The Ombudsman is free to use, does not require legal representation, and is the route for social housing tenants and many housing association tenants. Decisions are published at https://www.housing-ombudsman.org.uk/decisions/. The Ombudsman is explicit that it does not operate as a court — it does not make binding findings on negligence or liability, and it does not order damages in the way a court does. Its remedies are based on the published Guidance on Remedies (see “How the Housing Ombudsman assesses compensation” above).

Route 4 — County Court via the Pre-Action Protocol

For breach of repairing obligations, you can bring a civil claim in the County Court. Three statutory anchors usually apply:

• Section 11 of the Landlord and Tenant Act 1985 (primary source) implies a repairing covenant covering the structure and exterior of the dwelling, the installations for water, gas, electricity, and sanitation, and the installations for space and water heating. Breach of section 11 is the most common cause of action for damp and mould caused by structural defects, leaks, or failed installations. The court can order specific performance (i.e. order the landlord to actually do the works) under section 17 of the same Act.
• Section 9A of the Landlord and Tenant Act 1985 (inserted by the Homes (Fitness for Human Habitation) Act 2018) implies a separate covenant that the dwelling will be fit for human habitation throughout the tenancy. This applies where the dwelling is unfit because of prescribed hazards — which includes damp and mould assessed under the Housing Health and Safety Rating System. The court can order specific performance directly under section 9A itself.
• Section 4 of the Defective Premises Act 1972 and common-law claims in nuisance and negligence are also available in appropriate cases.

Before issuing proceedings, the Pre-Action Protocol for Housing Conditions Claims (England) must be followed. You send a detailed Letter of Claim; the landlord must respond within twenty working days; a joint expert typically inspects within a further twenty working days. Courts can order costs sanctions against parties who fail to comply with the Protocol.

Limitation periods: A claim under section 11 (contract) has a six-year limitation period from the date of breach. A personal injury claim, if any, has a three-year limitation period from the date of knowledge of the injury. These are statutory long-stops — you can lose your right to claim by waiting too long.

Legal aid:Housing legal aid is available for "homelessness, eviction, losing your home, or serious disrepair" subject to means and merits tests. Check eligibility at https://www.gov.uk/check-legal-aid.

Route 5 — Awaab's Law (social housing only, currently)

The Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025 — known as Awaab's Law — came into force on 27 October 2025. The Regulations impose statutory timescales on social landlords for investigating and remediating prescribed hazards in social housing. The key deadlines are:

• Emergency hazards: the landlord must investigate within 24 hours.
• Significant hazards: the landlord must investigate within 10 working days of becoming aware.
• Safety works for confirmed significant hazards: the lessor must secure that the relevant safety work is completed within 5 working days of investigation completing (Regulation 11(2)(a) of SI 2025/1042).
• Supplementary preventative works: must begin within 5 working days, with a 12-week longstop, and complete within a reasonable period.

Awaab's Law operates via an implied contractual term in social tenancies and is a fifth, distinct cause of action alongside sections 11 and 9A. It currently applies to social housing only; extension to the private rented sector has been announced as government intent but is not yet enacted. If your social landlord misses the Awaab's Law deadlines, see your legal options if a landlord breaks Awaab's Law for the routes available — the Housing Ombudsman, the council, and the courts.

The civil penalty of up to £40,000 that a council can impose on a landlord is paid to the local authority, not to you — it is enforcement, not tenant compensation. See our guide to penalties and enforcement.

Evidence that strengthens a claim

The strongest claims combine documentation of the conditions, documentation of every report to the landlord, and documentation of the impact. The Ombudsman has been explicit that resident engagement matters — refusing access, failing to communicate, or pursuing the complaint in an unreasonable way will weaken or remove a claim. The most useful evidence is:

• Dated photographs and short videos of every affected room, with a phone clock or newspaper visible to anchor the date.
• A written log of every conversation, phone call, text, email, or visit involving the landlord or their contractors. Note the date, the person, what was said, and what was promised.
• Copies of every written communication with the landlord — emails, letters, online portal messages, complaint submissions.
• Medical evidence where conditions have been affected by the damp — GP letters confirming symptoms or conditions, hospital records, prescriptions. The Pre-Action Protocol distinguishes between minor personal injury claims (a GP letter is sufficient) and substantial PI claims (the Personal Injury Pre-Action Protocol applies).
• Records of out-of-pocket costs — receipts for cleaning products, dehumidifier hire, alternative accommodation, travel, prescriptions, ruined belongings.
• Independent expert reports where the case proceeds to PAP — these are typically arranged as part of the Protocol procedure (single joint expert by default).

What evidence does not do, on its own, is overcome the mitigating factors above. The strongest evidence in the world matters less if you cannot show you communicated reasonably and gave the landlord a fair chance to put things right.

When the £19.99 Tenant Action Pack is the right tool

The Tenant Action Pack is a structured, step-by-step pack covering the same primary sources cited on this page. It is the right tool when:

• You are confident your case is straightforward and you want a defensible structure for documenting it and engaging the landlord without paying for solicitors.
• You want to follow the Complaint Handling Code 2024 timescales correctly, including drafting the right escalation letters at the right moments.
• You want a Pre-Action Protocol Letter of Claim template you can adapt yourself, knowing it matches the published Protocol annexes.
• You want a structured way to track evidence, log communications, and assess whether to escalate to the Ombudsman or proceed toward court.

The Tenant Action Pack is NOT the right tool if:

• Anyone in the household has respiratory symptoms attributable to the conditions, has been pregnant during the period, or is an infant.
• The conditions are dangerous (collapsing ceilings, exposed wiring, flooding, structural movement) and require emergency action.
• You believe a personal injury claim is realistic and you need legal advice on whether and how to pursue it.
• You are at or near a statutory limitation period.
• You are facing eviction proceedings linked to the disrepair complaint.

In any of those cases, contact a solicitor or Citizens Advice directly. The Law Society's Find a Solicitor service allows you to filter by housing specialism. Housing-related legal aid may be available — check https://www.gov.uk/check-legal-aid.

Frequently asked questions

How long do I have to make a claim?

The time limits vary by route. For a breach-of-contract claim under section 11 or section 9A of the Landlord and Tenant Act 1985, the limitation period is six years from the date of breach. For a personal injury claim within the same matter, the limitation period is three years from the date you knew (or should have known) about the injury. The landlord's internal complaint procedure has a twelve-month time limit — the issue must have occurred, or you must have become aware of it, within twelve months of filing the complaint. The Housing Ombudsman is reached after the internal procedure has been exhausted; there is no separate limitation period to escalate.

What if my landlord is a private landlord rather than a council or housing association?

Most of the routes above still apply. Sections 11 and 9A of the Landlord and Tenant Act 1985 apply to private tenancies of less than seven years (and certain longer fixed-term leases). The Pre-Action Protocol applies to all housing conditions claims regardless of landlord type. The Housing Ombudsman covers social housing including most housing associations; private tenants would typically use their landlord's redress scheme (if a member) or proceed directly to the County Court route. Awaab's Law currently applies to social housing only — extension to the private rented sector has been announced as government intent but is not yet in force.

Will I have to pay if I lose a court case?

The Pre-Action Protocol is designed to settle cases before litigation. If a case does go to court and the tenant loses, the tenant may be ordered to pay the landlord's costs, though housing disrepair cases often run on conditional fee arrangements ("no win, no fee") or under damages-based agreements that limit the tenant's downside. Legal aid may be available for housing disrepair claims — check https://www.gov.uk/check-legal-aid. For specific advice on costs risk, speak to a housing solicitor before issuing proceedings.

Can my landlord evict me for complaining about damp and mould?

Retaliatory eviction protections under the Deregulation Act 2015 provide a defence in some cases where a private landlord serves a section 21 notice after the tenant has raised legitimate complaints about housing conditions. The protections are imperfect and have been subject to ongoing legislative review. If you are concerned about eviction risk, do not let that stop you raising the issue, but get advice early from Citizens Advice or a housing solicitor. Social landlords typically cannot evict for raising legitimate disrepair complaints.

What evidence should I be gathering right now?

Photographs and short videos with the date visible (phone clock or newspaper), a dated log of every report you make to the landlord, copies of every written communication, GP letters for any health symptoms, and receipts for out-of-pocket costs (cleaning, dehumidifier hire, alternative accommodation, prescriptions, ruined belongings). Lifestyle factors can become mitigating arguments by the landlord — ventilate the property where possible and document that you have done so, while still maintaining your claim that the underlying cause is the landlord's responsibility.
