Please complete our impact survey (here) It’s been more than a year since homeowners in the Gower Estate, Hirwaun, were told that their homes were built using a dangerous, obsolete material called Reinforced Autoclaved Aerated Concrete (RAAC)—a product which many believe to have had a lifespan of just 30 years. And yet, for many of these residents, life has stood still ever since.
Now, they face an impossible choice: pay tens of thousands of pounds for questionable repairs, or continue living in crumbling homes with no clear end in sight.
77 Homes Affected, But No Permanent Fix in Sight
In February 2024, it was confirmed that 77 homes on the estate were affected by RAAC—60 under Trivallis Housing and 17 privately owned. The housing association offered a so-called “permanent solution” at an average cost of £23,000 per homeowner, but that promise quickly unraveled under scrutiny.
According to Lesley Lewis, Chair of the Cymru RAAC Campaign Group, and direct communication with the contractor CS Phillips, the proposed solution is anything but permanent. The company itself reportedly admitted that continued monitoring of the deck system would be necessary, and that deterioration could still progress—potentially leading to further costly interventions. Rhondda Cynon Taf Council outlining the Trivallis Housing proposal:
"The solution identified by Trivallis is known as a ‘safety deck system’ which involves fitting a structurally designed wooden safety deck under the RAAC panels in the home to make them secure. Trivallis have advised that this solution will permanently stop the risk of the panels collapsing and will protect the roof, electrical wiring, insulation, and decoration in the property.
Their plan has been carefully designed by a team of experts who deal with difficult structural problems. The solution involves installing a wooden safety deck in a specific way to all ceilings on the upper floor of the property. This deck will keep the RAAC panels in place, making sure that they stay permanently stable and secure.
To make the solution even stronger, Trivallis have advised they will also be adding a layer of plywood on top of the deck. This plywood will retain very small pieces of RAAC which might break off from the panels in the future and is an important safety measure to keep the home safe long term.
Trivallis have advised this is a permanent solution and further works to make the RAAC safe will not be required. The solution is likely to make the ceiling height of upper floors slightly lower but will keep the home safe.

Wilson Chowdhry, Chairman of the UK RAAC Campaign Group, said:
"I’m deeply concerned that both the Welsh Government and the local authority appear to naively consider the ‘Safety Deck system’ a permanent solution. Any approach that leaves crumbling, dangerous RAAC in place cannot be regarded as long-term. Spending £23,000 on a temporary fix that still traps homeowners as mortgage prisoners and risks making homes uninsurable is not just short-sighted—it’s senseless."
To make matters worse, CS Phillips is not a structural roofing or RAAC specialist but a property developer, leaving serious doubts about whether they are equipped to deal with this crisis at all.
Grant Scheme Unfit for Purpose—and Already Failing Residents
While the Welsh Government has announced grants of up to £35,000—based on pre-existing local authority schemes—these offerings are proving woefully inadequate for the scale and urgency of the RAAC crisis. The primary repair plan leaves homeowners facing a shortfall of around £17,000 each, a sum that is simply out of reach for many, particularly elderly and retired residents.
Worse still, the current grant system appears to be a repurposed stopgap, never intended for a structural emergency of this magnitude. It lacks the flexibility and scope required to address the unique challenges posed by RAAC.
Already, one homeowner has had their application denied, and one other has been advised that they do not meet the rigid eligibility criteria. The reality is clear: these schemes were never built with this scandal in mind—and beleaguered homeowners are paying the price.
This leaves homeowners, many of whom are elderly or retired, trapped in homes that may now be unsellable and uninsurable. And with properties physically linked to neighbouring Trivallis homes, independent remedial work for private owners isn’t even an option.
In a letter to Mrs Lewis, the Weslh Assembly wrote:
"In respect of private homeowners, I am aware that the Local Authority has engaged homeowners and offered grant assistance via its normal financial support arrangements. It is my understanding that some homeowners have not yet undertaken any surveys to identify the extent of the RAAC within their homes. As a first step I would strongly encourage all homeowners to undertake surveys and to engage with the Local Authority who stand ready to support them and discuss options.
The Welsh Government is not able to offer direct interest free loans to cover costs for works undertaken. There are however a number of funding options, grants and loans available through Rhondda Cynon Taf CBC. I have for completeness under annex A attached a copy of the potential financial support available from the Council.
Welsh Government continue to monitor the situation through engagement with both the Local Authority and Trivallis."

A Deafening Silence from Authorities
Residents describe a complete lack of communication from Trivallis and Rhondda Cynon Taf Council. Carol Evans, a long-time resident, said she has been left “mentally and physically” unwell by the stress. Malcolm Twigg said "Nobody is helping us at all. We are on our own.” Linda Page put it simply: “We are just sitting in limbo.”
Mr. Chowdhry, Chairman of the UK RAAC Campaign Group, wrote to the council on 20th May 2024 requesting the opportunity to represent local homeowners through a formal deputation. The response he received was brief and dismissive:
"Dear Mr. Chowdhry,
Thank you for your email below.
We have noted your request and wish to advise you that, as a Council, we have not identified any substantive issues relating to RAAC within the Council estate.
Kind regards,
Julia Nicholls"
The tone and content of the response made it clear that the council was unwilling to engage meaningfully on the issue. Rather than acknowledging the growing crisis faced by residents, the response appeared to downplay concerns and avoid any form of responsibility or involvement.
The human cost of this scandal cannot be overstated. These are not just houses; they are people’s homes, their security, their life savings—and for many, their future.
What Needs to Happen Now
The RAAC scandal is a national failure, but the Gower Estate is its ground zero in Wales. These homeowners are the first to feel the consequences, but they will not be the last unless immediate and meaningful action is taken.
We call on Rhondda Cynon Taf Council, Trivallis Housing, and the Welsh Government to:
Commission independent, expert-led assessments of all remediation plans and the contractors executing them. Residents deserve credible, transparent, and accountable solutions.
-
Reform and expand the grant scheme so no homeowner is excluded due to arbitrary criteria or excessive red tape. This crisis demands tailored support—not recycled funding models.
-
Engage with affected residents transparently and consistently, ensuring they are fully informed and meaningfully consulted at every stage of decision-making.
-
Provide targeted financial relief and dedicated mental health support for residents who have endured prolonged uncertainty, displacement, and psychological strain.
-
Challenge the UK Government to amend the Financial Services Act, so banks are prohibited from charging interest on mortgages for homes rendered uninhabitable by no-fault safety issues like RAAC.
-
Push for the restoration of first-time buyer status for any homeowner whose property is condemned due to systemic construction faults beyond their control.
-
Introduce a UK version of the EU’s General Safety Product Regulation (GSPR)—offering 50-year protections for homeowners impacted by building materials later found to be unsafe. Developers, manufacturers, and governments must be held accountable.
-
Establish a national ‘High Risk Homes Register’ to flag unsafe or defective properties and ensure buyers are protected and properly informed.
These families did not cause this problem—they bought homes in good faith. Now, they are being asked to pay the price for historic construction failings and years of regulatory neglect.
If we don’t act now, the Gower Estate could become a blueprint for how not to manage a national housing emergency.
Wilson Chowdhry added:
"Many affected homeowners—predominantly those over 70—now face the very real prospects of bankruptcy and homelessness. Securing external lending for these safety works will be almost impossible, especially given that these properties sit in areas ranked among the most deprived. It’s crucial to remember that these homes were sold under the UK Government’s Right to Buy scheme—a policy heralded as a pathway to affordable, equitable homeownership. Those ambitions have been dashed, and it’s time to make good on the promise and put things right."
On Saturday 10th May, Wilson Chowdhry will visit the Hirwaun community to meet with RAAC-affected homeowners and support them in establishing a formally constituted group to advance their campaign for justice and remediation. Mr. Chowdhry has also submitted an online petition to the Welsh Government, which is currently undergoing the approval process.
