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.

Average Cardiff compensation
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.

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).
