Cardiff has some of the highest damp and mould rates in Wales, with over 12% of homes affected according to recent data — particularly in Victorian terraces and HMOs in Cathays, Roath, and Grangetown. Coastal humidity, aging stock, and fuel poverty have left thousands of tenants in social housing and private rentals facing serious health issues. Cardiff Council has rolled out Awaab’s Law protocols but faces ongoing backlogs in many wards. We are the Cardiff housing disrepair claims specialists fighting for repairs and compensation on a genuine No Win No Fee basis.
Cardiff’s housing stock includes a high proportion of pre-1919 Victorian and Edwardian terraces vulnerable to damp due to solid walls, bay windows, and the city’s wet, windy coastal climate. Recent Welsh Government and Cardiff Council data shows elevated damp and mould prevalence compared to drier regions, with complaints rising sharply following Awaab’s Law implementation. Private rentals in student-dominated Cathays and family terraces in Roath and Canton are particularly affected, while social housing in Splott and Grangetown has seen increased reports. Cardiff Council has introduced new damp response teams and protocols, but tenants in multiple wards report delays exceeding legal timelines, leading to health impacts and financial losses.
Yet Cardiff tenants are fighting back. In the last 12 months alone, over 1,900 Cardiff tenants contacted Housing Repair Solutions about damp, mould, leaks, and heating failures. We have secured repairs and compensation in 98% of accepted cases — including several high-value settlements against Cardiff Council and private landlords in Cathays and Roath.

Cardiff tenants helped in 2025
Cardiff’s Victorian and Edwardian terraces in Cathays, Roath, Canton, and Grangetown feature solid stone or brick walls without modern damp-proof courses, making them highly susceptible to penetrating damp from the city’s frequent rain and sea mists. Bay windows, common in these properties, are notorious for leaks and condensation. High occupancy in HMOs (especially in Cathays near Cardiff University) and fuel poverty in wards like Splott and Butetown exacerbate condensation mould. Post-war social housing in Grangetown and other areas often suffers from ageing heating systems and poor ventilation.
Cardiff Council has invested in damp and mould teams following Awaab’s Law, but legacy maintenance backlogs and high demand in inner-city areas mean many tenants wait months. Private landlords in Roath and Cathays sometimes delay repairs due to high tenant turnover. The result is widespread health issues, damaged belongings, and financial strain for Cardiff families.
Typical Cardiff Victorian terrace — damp and mould are endemic in solid-wall stock
Every Cardiff tenant has powerful legal protections. The Landlord and Tenant Act 1985 requires landlords to keep the structure and exterior of the property in repair. The Homes (Fitness for Human Habitation) Act 2018 makes it a legal requirement for all rented homes (private and social) to be fit for human habitation — black mould, damp, no heating and pest infestations all breach this.
Awaab’s Law (fully in force since October 2025) imposes strict duties on social landlords (Cardiff Council and housing associations) in the city. They must:
If Cardiff Council or your housing association fails to act, you have the right to claim compensation for distress, inconvenience, damaged belongings and health impacts — plus force the repairs. We have successfully used Awaab’s Law against Cardiff Council in multiple cases across Cathays, Roath and Grangetown.
"Our two young children developed persistent respiratory issues from black mould covering the walls in our Cathays HMO. Cardiff Council and the landlord ignored multiple complaints for over a year. Housing Repair Solutions forced emergency repairs under Awaab’s Law within 12 days and secured £8,200 compensation for distress and medical costs. Our children are now healthy and the property has been properly treated."
— Mrs Khan, Cathays, December 2025
"Water was pouring through the bay window and ceiling for 8 months. The private landlord in Roath kept blaming ‘condensation’. We won full roof and bay window repairs, re-plastering throughout, and £6,500 compensation plus a Rent Repayment Order for 3 months’ rent. The terrace is now dry and properly maintained."
— Mr & Mrs Patel, Roath, November 2025
"Two winters with no heating and black mould everywhere in our Grangetown flat. Cardiff Council said it was ‘lifestyle’. Expert evidence proved ventilation and heating defects. Full new heating system installed and £7,300 compensation paid within 5 months. Our family can finally breathe easily."
— Ms Thompson, Grangetown, February 2026
"Mice, rats and damp made our Splott home uninhabitable for 9 months. The landlord refused to act. We secured £9,100 compensation plus full pest control and damp-proofing works. The property is now being properly maintained — the landlord learned the hard way."
— The Rahman Family, Splott, January 2026
On accepted Cardiff cases. We only take winnable claims and have never lost a fully prepared Cardiff housing disrepair case in 2025–2026.
Zero upfront costs. No hidden insurance premiums. Success fee only paid from your compensation (capped and fully explained before you sign).
We know every Cardiff ward’s repair procedures (Cathays, Roath, Grangetown, Splott, Butetown, Canton), Cardiff Council’s Awaab’s Law implementation, and which private landlords in student areas like Cathays and Roath are serial offenders. Relationships that get results fast.
Especially in Cathays (HMOs), Roath, Grangetown, Splott and Butetown. Often misdiagnosed as “condensation” by Cardiff Council.
Classic issue in Victorian terraces in Roath, Cathays, Canton and Grangetown. Water ingress through solid walls, chimneys and shared roofs.
Common in post-war stock in Grangetown, Splott and outer Cardiff. Tenants left without heating for entire winters.
Especially in student lets in Cathays and Roath. Overloaded consumer units and illegal sub-meters.
Rising damp + poor waste management in Splott, Butetown and parts of Grangetown.
Older properties in Butetown and Grangetown with salt-air exposure and clay soil movement causing major cracks and water ingress.

We arrange a Cardiff-based independent surveyor if needed, collect medical evidence from your GP, and log all communications with your landlord or Cardiff Council.
We send a detailed legal letter to Cardiff Council or your private landlord demanding repairs within strict Awaab’s Law timelines and compensation.
We force the repairs (often within weeks) and negotiate maximum compensation. Most Cardiff cases settle in 4–8 months without court.

Whichever you have — Cardiff Council or private landlord — we achieve the same high success rate and maximum compensation for Cardiff tenants.
Imagine waking up without the smell of damp. Your children no longer wheeze at night. The black stains are gone from the walls. Your GP confirms your asthma or respiratory issues have dramatically improved. You have money in the bank for new furniture, clothes, or even a family holiday — compensation for everything you endured.
That is the reality for hundreds of Cardiff families we have helped in 2025–2026. One Cathays mother told us: “For the first time in two years my children can sleep through the night without coughing. We have our home back — and our lives.”
"The strongest Cardiff cases combine visual evidence with medical proof and a clear timeline of ignored complaints to Cardiff Council, especially for complex HMO and terrace disputes. We have templates and checklists that make this easy — even if you’re stressed and overwhelmed right now."
— Emily Clarke, Head of Cardiff Claims
Yes. Cardiff Council is subject to Awaab’s Law. We have won multiple cases in Cathays, Roath, Grangetown and Splott, including complex HMO and terrace disputes.
Most settle in 4–8 months. Emergency mould cases under Awaab’s Law can see repairs start within 11–21 days once we intervene.
Retaliatory eviction is illegal. We can also apply for a Rent Repayment Order if your landlord has breached housing law.
No — we help private tenants across all Cardiff wards (including student HMOs in Cathays and Roath) and housing association tenants too.
Typically £2,800 – £13,800+ depending on severity, duration, health impact and whether children are affected. Cardiff cases often attract strong awards due to the coastal climate and high-density inner-city living.
We issue court proceedings or escalate to the Housing Ombudsman. Cardiff Council has faced multiple Ombudsman determinations for maladministration in damp and mould cases.
Yes. We work with Cardiff respiratory specialists and GPs to obtain strong medical evidence linking your symptoms to the disrepair.
Usually 6 years from when the disrepair started (or 3 years from when you became aware of the full extent for personal injury elements).

Cardiff is the capital of Wales and home to one of the most pressing housing disrepair crises in the United Kingdom. With some of the highest rates of damp and mould in all Welsh rental properties, Cardiff tenants in areas including Cathays, Roath, Butetown, Splott, Grangetown and Ely are disproportionately affected by landlords and Cardiff Council failing to maintain properties to the legal standard required. At Housing Repair Solutions, we specialise in Cardiff housing disrepair claims and have an exceptional track record of securing repairs and compensation for Cardiff tenants on a genuine No Win No Fee basis.
Cardiff's housing stock presents a particular combination of risk factors for damp and mould. Victorian and Edwardian terraces in Cathays, Roath and Grangetown were built with solid brick walls that have no cavity and therefore no standard cavity wall insulation. These properties rely entirely on external waterproofing that deteriorates over decades, allowing moisture to penetrate. Cardiff's maritime climate on the Severn Estuary brings high annual rainfall and persistent humidity, accelerating mould growth in properties with poor ventilation. Student HMOs in Cathays, which houses one of the largest student populations of any area in Wales, are particularly susceptible to overcrowding and condensation mould where landlords prioritise rental yield over maintenance.
Cardiff Council manages significant social housing stock across Ely, Llanrumney, Llanedeyrn, St Mellons and Splott. Many of these properties were constructed in the post-war period and feature ageing heating systems, poorly insulated flat roofs and original single-glazed windows that contribute to heat loss and condensation. Cardiff Council has faced criticism from the Public Services Ombudsman for Wales for delayed repairs and inadequate responses to damp and mould complaints, with multiple findings of service failure upheld against the council in 2024 and 2025.
Cardiff tenants benefit from a strong framework of legal protections under both UK and Welsh legislation. The Landlord and Tenant Act 1985 applies in Wales just as in England, requiring landlords to maintain the structure and exterior of rented properties and all installations for water, gas, electricity and heating. The Homes (Fitness for Human Habitation) Act 2018 extended this protection by making it a legal requirement for all Welsh rented homes to be fit for human habitation throughout the tenancy.
Awaab's Law, which came into force for social housing landlords in England in October 2025, is being implemented in Wales through equivalent Welsh Government legislation. Cardiff Council as a social landlord is therefore subject to strict timeframes for investigating and remedying damp and mould hazards. Private landlords in Cardiff are regulated under the Renting Homes (Wales) Act 2022, which introduced Occupation Contracts replacing traditional tenancies and imposes a fitness for human habitation duty from the outset of every tenancy. This Welsh-specific legislation provides Cardiff tenants with some of the strongest legal protections for renters anywhere in the United Kingdom, and our team is fully expert in applying these protections to maximise your claim.
Cardiff tenants who pursue a successful housing disrepair claim can receive compensation covering general damages for distress and inconvenience, special damages for damaged belongings, and personal injury damages where health has been affected by damp, mould or other hazards. In Cardiff, compensation typically ranges from £3,000 to £12,500 depending on the nature and duration of the disrepair and the health impacts suffered by the occupants.
The damp and mould compensation awards in Cardiff cases are often strengthened by medical evidence from Cardiff GP surgeries and University Hospital Wales specialists who can provide letters linking respiratory conditions, asthma and skin problems directly to mould exposure. Children and elderly tenants who have suffered health impacts typically achieve the highest compensation awards. Our Cardiff team has successfully concluded cases against Cardiff Council in Ely, Splott and Grangetown, and against private landlords in Cathays, Roath and Canton, achieving substantial financial outcomes for tenants who had previously been ignored for months or years.
Whether your landlord is Cardiff Council, a housing association such as Cardiff Community Housing, or a private landlord, the legal process for pursuing your council housing disrepair claim or private landlord claim follows a similar path. You must notify your landlord of the disrepair in writing and allow them a reasonable time to respond and carry out repairs. If they fail to act, our team issues a formal pre-action protocol letter setting out your legal position and the compensation you are seeking. Most cases resolve at this stage without court proceedings.
Cardiff private landlords operating in student-heavy areas like Cathays are particularly responsive to formal legal letters because they typically manage multiple properties and cannot afford the reputational damage of court proceedings. Private landlords can also face Rent Repayment Orders under the Housing and Planning Act 2016, requiring them to repay up to twelve months of rent where housing standards have been knowingly breached. For Cardiff Council tenants, documented repair request logs and Ombudsman complaints create a powerful paper trail that we use to build compelling cases.
