Statement of support

In the face of rising housing demand, construction costs and carbon reduction targets, ClwydAlyn, Isle of Anglesey County Council and Williams Homes (Bala) developed a partnership demonstrating what can be achieved when a registered social landlord, local authority and private sector developer work together.

The partnership was built around a goal: increasing the supply of affordable homes on Anglesey while tackling fuel poverty and supporting sustainable communities. As housing need grew, all three organisations recognised the need for a solution that could accelerate delivery, reduce risk and create social value.

Building on a longstanding relationship forged through previous housing developments, the partners established a collaborative delivery model combining ClwydAlyn’s development expertise, the council’s housing ambitions and Williams Homes’ construction capability and local knowledge.

ClwydAlyn led the development process, managing design, stakeholder coordination and project delivery. The council provided strategic direction, ensuring the scheme responded directly to local housing needs and supported community objectives. Williams Homes played a pivotal role as construction partner, bringing expertise in quality housebuilding, programme management and delivery. Together, the partners maintained rigorous standards, supported by ClwydAlyn’s technical team and clerk of works function.

A challenge emerged when administrative constraints made the council’s funding mechanism unworkable. Rather than allowing progress to stall, the partnership found a solution. ClwydAlyn stepped in to cashflow the development and create a turnkey delivery model, while Williams Homes maintained momentum on-site and the council remained focused on securing housing outcomes. This approach enabled the homes to be transferred seamlessly on completion, removing barriers that could otherwise have delayed delivery.

The partnership is showcased at Pentraeth, where 23 EPC A-rated affordable homes were delivered through a mixed-tenure approach. Thirteen homes were retained by  ClwydAlyn for social rent allocations through the housing register, while 10 homes were sold to the council for intermediate rent through Tai Teg. Working together from concept to completion, the partners ensured the development met a range of local housing needs while maximising community benefit.

The collaboration demonstrated how strong partnerships can navigate planning challenges. ClwydAlyn, the council and Williams Homes worked closely to deliver homes within a sensitive setting while incorporating sustainable drainage systems, public open spaces and a community orchard, ensuring the development enhanced its surroundings.

Innovation sits at the heart of the project. Through collaboration, the homes were built using modern methods of construction and local Welsh timber-frame technology. Williams Homes’ build expertise and offsite workshop inside HMP Berwyn were instrumental in driving these methods. Simultaneously, ClwydAlyn and the council ensured sustainability and community impact remained central to the vision. Crucially, the initiative delivered social value through an offender mentoring programme at HMP Berwyn, where inmates manufactured timber panels, equipping 25 individuals with industry qualifications and pathways to future employment.

Sustainability benefits have been impressive. The homes include high-performance wood-fibre insulation, air-source heat pumps and solar photovoltaic panels, creating energy-efficient homes that exceed regulatory standards. These features help reduce energy consumption, lower household costs and support health and wellbeing for residents while contributing to environmental goals.

The partnership extends beyond construction. ClwydAlyn manages shared public open spaces, sustainable drainage infrastructure and landscaping on behalf of residents, invoicing the Council annually for its agreed share. This arrangement ensures long-term asset management and maintains neighbourhood quality for future generations.

Importantly, the model is transferable. By combining ClwydAlyn’s development expertise, the council’s strategic leadership and Williams Homes’ construction capability, the partnership has created a blueprint that can support affordable housing delivery at pace. Together, the organisations have shown how partnerships can overcome financial, operational and environmental challenges to deliver sustainable homes that strengthen communities and improve lives across North Wales.

Outcomes and achievements

The partnership between ClwydAlyn, Isle of Anglesey County Council and Williams Homes (Bala) delivered a practical and scalable housing model that combines sustainable construction, financial flexibility and strategic ambition.

 At Pentraeth, the partnership delivered 23 EPC A-rated affordable homes through a mixed-tenure approach, comprising 13 social-rented homes managed by ClwydAlyn and 10 intermediate-rental homes managed by the council through Tai Teg. Delivered using modern methods of construction and Welsh timber, the homes feature air-source heat pumps, solar PV and enhanced insulation, reducing energy use and tackling fuel poverty.

ClwydAlyn cashflowed the development and implemented a turnkey acquisition model. Williams Homes maintained construction progress and quality standards, while the council ensured the homes met identified housing needs. This collaborative approach enabled delivery of affordable housing without increasing development risk or requiring additional local authority delivery capacity.

The scheme generated social value through its partnership with HMP Berwyn, where the manufacture of timber wall panels helped 25 inmates gain construction-related qualifications; improving future employment prospects.

Residents are benefiting from lower household costs, improved wellbeing, greater housing security and stronger community connections. Importantly, the partnership has established a proven model that can be replicated across Wales to accelerate delivery of sustainable affordable homes.
