Welsh Housing Association Criticised Over Years of Damp, Mould and Repair Failings
Tenants were left dealing with damp, mould, poor communication and delayed repairs, including one case where problems continued for nearly seven years.
Welsh housing association Trivallis has been criticised following findings by the Public Services Ombudsman for Wales, according to recent reports. The Ombudsman investigated complaints from two tenants, Mr B and Mrs C, about how Trivallis responded to damp and mould. Mr B’s complaint also involved delays in dealing with a broken boiler. The Ombudsman said the cases raised concerns about possible systemic failings, including poor record-keeping, missed opportunities to act, and failures to properly consider vulnerable residents.
For social housing tenants, the findings are worrying because they show how disrepair can continue for long periods when landlords fail to investigate properly, communicate clearly or act on repeated reports.
What did the Ombudsman find?
In Mr B’s case, the Ombudsman found that Trivallis failed to respond appropriately to reports of damp and mould. Outstanding repair issues persisted for nearly seven years, and reports were not handled in line with relevant policies and guidance. The Ombudsman also found that delays in repairing a broken boiler left Mr B unable to heat his home properly while awaiting the repair.
The boiler issue was eventually repaired after Mr B’s wife complained. The Ombudsman said residents should not have to make complaints to their landlord before urgent repairs are completed.
In Mrs C’s case, surveys found moisture in the same area of her home, leading to damp and mould, but the cause had not been confirmed. The Ombudsman also found that Trivallis’ communication with Mrs C was not always appropriate, and that the needs of her disabled granddaughters were not clearly considered.
The Ombudsman said the failings may be systemic, pointing to weaknesses such as inaccurate records, missed opportunities to act on repeated repair requests and failures to properly consider vulnerable residents.
Why damp, mould and heating problems matter
Damp and mould should never be treated as minor problems. They can affect a tenant’s health, damage belongings and make a home unpleasant or unsafe to live in. For households with children, elderly relatives, disabled residents or people with respiratory conditions, the impact can be even more serious.
A broken boiler can also be a major issue, especially during colder months. If tenants cannot heat their home properly, damp and mould may worsen, and the property may become uncomfortable or unsuitable for day-to-day living.
Premier Legal Assist supports tenants affected by damp and mould, faulty plumbing, heating and boilers, leaks and water damage, and other housing disrepair claims.
Housing association duties to tenants in Wales
Housing associations are expected to keep homes safe, habitable and in a reasonable state of repair. In Wales, the relevant legal framework includes the Renting Homes (Wales) Act 2016 and the Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022.
Welsh Government guidance explains that, from 1 December 2022, landlords must ensure rented homes in Wales are “fit for human habitation”. The guidance for landlords says homes must be in good repair and fit to live in, while tenant guidance explains what landlords must do under the fitness for human habitation rules.
The Fitness for Human Habitation rules include factors to consider when deciding whether a home is fit to live in. These include damp and mould growth, excess cold, fire safety, electrical hazards and other risks to health and safety.
Tenants should report problems as soon as they become aware of them. Once a landlord has been notified, it should take appropriate action within a reasonable time. This may include inspecting the home, identifying the root cause, arranging repairs, keeping the tenant updated and checking whether the work has resolved the issue.
Where the same problem keeps being reported, landlords should look beyond surface treatment. Repeated damp or mould may point to an underlying repair issue, such as water ingress, poor ventilation, defective windows, leaks or inadequate heating.
Social housing law in England and Wales
The legislation around social housing is different in England and Wales, but landlords still have a responsibility to their tenants.
In England, Awaab’s Law came into force for social landlords on 27 October 2025, introducing strict timeframes for dealing with emergency hazards and significant damp and mould hazards in social housing.
In Wales, tenants are protected under Welsh housing law, including the Renting Homes (Wales) Act 2016 and the Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022. These rules require landlords to make sure rented homes are fit to live in, including taking issues such as damp, mould, excess cold and other health and safety risks seriously.
Regardless of where a tenant lives, social landlords should not ignore serious repair problems or leave people living in homes that are unsafe, unhealthy or unsuitable.
What rights do social housing tenants have?
Social housing tenants have the right to live in a safe and properly maintained home. This applies whether their landlord is a council or a housing association.
If a landlord fails to deal with reported repairs, tenants may have options. These may include:
- Making a formal complaint to the landlord
- Asking for a clear repair plan and timescale
- Keeping evidence of the problem and all communication
- Escalating an unresolved complaint to the relevant Ombudsman
- Seeking legal advice
- Exploring whether they may be able to make a housing disrepair claim
Useful evidence can include photographs, videos, repair reference numbers, emails, complaint responses, medical information, damaged belongings and a diary of when problems were reported.
The Ombudsman and compensation routes
In Wales, complaints about housing associations can be considered by the Public Services Ombudsman for Wales. In England, social housing complaints are usually considered by the Housing Ombudsman Service, which deals with complaints about councils and housing associations.
The Ombudsman can investigate complaints, make findings and recommend action, including repairs, apologies and compensation. However, the Ombudsman process can take time and may not always provide the urgent or enforceable outcome that tenants need. The Ombudsman can recommend action, but it cannot force a landlord to take it.
Tenants may also wish to seek legal advice, especially where repairs have been delayed repeatedly, the home is unsafe or unfit to live in, damp or mould has affected health, belongings have been damaged, or the landlord has failed to act despite repeated reports.
A housing disrepair claim may help tenants seek repairs and, where appropriate, compensation. Compensation may reflect factors such as the length of time the home was affected, loss of enjoyment of the property, damaged belongings, inconvenience, and the impact on health or day-to-day life. The exact position will depend on the evidence and the circumstances of each case.
