Summary
Summary
The Welsh Government Energy Service supports public sector decarbonisation by enabling projects that are designed, installed and maintained in Wales. DA Hughes, an electrical and renewable energy contractor based in Denbighshire, is a clear example of the Welsh supply chain at work: a locally rooted SME delivering solar PV, battery energy storage systems (BESS) and electric vehicle charging infrastructure (EVCI) across North Wales while training apprentices and creating skilled employment.
The business has adapted through four decades of market change, from early electrical contracting, through the Feed‑in Tariff (FIT) era, to today’s smart PV plus storage and EV integration. DA Hughes now employs eleven people, including three apprentices, with solar and storage accounting for around half of its work. Through Energy Service funded projects, the company has delivered installations across schools, leisure centres and council estate, alongside privately funded work for rural estates and local SMEs.
Context: the Welsh supply chain
Public sector decarbonisation depends on a delivery system that is resilient, investable and scalable. In Wales, this means local capacity to design, install and maintain low‑carbon systems; skills pathways that bring new entrants into the sector and upskill existing trades; economic value retained in Wales; and practical delivery for public assets such as schools, leisure centres, offices and housing, often under tight operational constraints.
Energy Service projects increasingly require integrated solutions: solar PV, export‑limited connections, battery storage for peak management, and EV charging with smart control. The Welsh supply chain therefore needs to cover electrical design, grid compliance, commissioning, handover and ongoing performance support.
Supplier profile: DA Hughes, Denbighshire
DA Hughes is a Welsh SME that has built capability incrementally over four decades. The company traces its origins to 1985, when the founder began in the electrical trade at 18 and later established an independent practice. In 2004, the business formalised under Part P and began taking on employees and apprentices, embedding training as part of business‑as‑usual.
From 2011 the company became MCS certified for solar PV, reflecting the shift from conventional electrical contracting to renewables delivery during the FIT era. Like many installers, it experienced supply constraints and market volatility, including periods when panels were difficult to secure, and returned to MCS in 2021 as the market matured into today’s PV plus storage demand. DA Hughes remains a strong electrical contractor, with renewables now accounting for approximately half of its work. This long‑term capability building creates expertise that stays in Wales and can be mobilised quickly for public sector delivery.
Project delivery in North Wales
DA Hughes has delivered schemes across Denbighshire, Gwynedd and wider North Wales. The examples below illustrate both technical breadth and operational adaptability.
Leisure centre solar PV with battery storage
A representative project combined around 100 kWp of rooftop solar PV on a leisure centre with two battery units of approximately 215 kWh each (around 430 kWh in total). The configuration supports daytime load matching and can reduce peak import, improving value for the public estate.
EV charging with battery storage
In another scheme, DA Hughes delivered a PV and storage project integrated with 12 EV chargers. The operational profile was designed around fleet use, with refuse vehicles operating from early morning through mid‑afternoon, so battery charging and discharge could be aligned to the charging window.
Schools and public buildings
The company has installed solar PV at around 10 schools in Denbighshire and at further schools, leisure centres and office buildings in Gwynedd. Repeatable delivery across similar assets is central to scaling decarbonisation efficiently.
Rural and commercial estates
Work in agricultural and rural settings includes a planned PV and storage scheme for a milking farm and an estate site where PV supports farm retail and hospitality. These projects show the Welsh supply chain serving both public and private assets, helping to stabilise demand for skills and materials.
Community energy and legacy schemes
DA Hughes has also supported community‑scale renewables, including hydro projects delivered during the FIT era, demonstrating experience of local, community‑led delivery alongside mainstream public sector procurement.
Skills, apprenticeships and upskilling
The business consistently reports that finding work is easier than finding suitably qualified workers, with skills shortages now a key constraint across the sector. DA Hughes addresses this through direct training and clear progression routes.Three apprentices are currently in training, supported through Welsh further education at Coleg Cambria and Grŵp Llandrillo Menai. The company also develops in‑house capability across design support, payback calculations and grid connection applications. One practical example is the internal capacity to manage G99 grid connection applications for larger generation and storage systems, which is increasingly essential for PV and BESS projects and reduces reliance on external consultants.
Quality and long-term performance
Public sector projects require systems that work reliably for years, with clear handover and accessible monitoring. DA Hughes uses a standard approach to commissioning and user support: a written handover pack, demonstration and set‑up of monitoring including app‑based tools, and use of online portals for performance oversight and troubleshooting.
The company has also navigated price volatility and supply disruption, including sharp changes in panel costs in the early period of the war in Ukraine. Contractors who have managed this volatility are better placed to deliver public programmes at pace while maintaining quality and compliance.
Conclusion
DA Hughes illustrates the elements the Energy Service needs from the Welsh supply chain: local delivery capacity across PV, BESS and EV charging; the ability to scale from small social housing systems through to larger multi‑technology schemes; grid and compliance competence, including export management and connection applications; a commitment to training rooted in Wales; operationally informed delivery designed around how sites actually run; and quality handover with ongoing performance support.
The transition to a net zero public estate in Wales depends on delivery capability on the ground as well as capital funding and policy ambition. DA Hughes demonstrates that Wales has a capable and evolving installer base of Welsh jobs, Welsh apprentices and Welsh SMEs delivering technically robust energy projects across North Wales. The Energy Service role is to continue enabling this market: supporting the pipeline of projects that allows local companies to invest in people, equipment and accreditation; strengthening frameworks accessible to public bodies; and ensuring the benefits of decarbonisation are retained in Wales through local employment and skills.
