Design & Consultancy - Renewable Energy Experts in Carmarthenshire & Wales

Renewable energy has always been our passion, not just our business. With over 20 years of hands-on experience, we’ve established ourselves as pioneers here in Carmarthenshire, Wales, known for our practical, honest approach and commitment to sustainability.


Our foundation was a master’s degree (MSc) in Renewable Energy and the Built Environment from the Centre for Alternative Technology (CAT) in Machynlleth. This deep understanding, combined with decades of real-world experience, means we understand the why, not just the how, behind every system we design.


We’ve spent years helping homeowners, farms, and businesses transition to renewable energy with confidence. From rural off-grid properties to large commercial buildings, our projects are designed around real-world performance, efficiency, and value — not just box-ticking or sales figures.

Honest Renewable Energy System Design, Tailored to You

We believe a great renewable energy system starts with a proper design, not just a sales quote. Every property is different, and so are the people who own them. That’s why we take the time to listen, assess, and design systems that fit your energy needs, lifestyle, and long-term goals.

We guide your project from the earliest stage of site assessment through to design, planning, and system integration. Our comprehensive design service handles all the technical details for you:

We’ve successfully designed systems for a wide range of clients across England and Wales — including private homeowners, farms, housing associations, local authorities, and large commercial and industrial premises. Whatever the scale or sector, our goal is always the same: to create efficient, well-integrated systems that stand the test of time.

Making Renewable Technologies Work Together

Our speciality lies in creating smart, cost-effective solutions by integrating multiple technologies. Our expertise covers heating, biomass, solar PV, heat pumps, battery storage, and solar thermal systems — allowing us to design complete off-grid systems or upgrade existing installations for maximum performance. We understand how these technologies work together, maximising efficiency and reducing running costs. For example, solar PV and battery storage can reduce dependency on the grid, while heat pumps and thermal systems can balance energy use throughout the year. We only recommend what is grounded in data, proven by experience, and right for your property.

Independent Renewable Energy Consultants in Wales

As independent consultants, we’re not tied to any single manufacturer or technology. That means our advice is independent and focused entirely on what’s right for you. We can work alongside your existing contractors or manage the full design process ourselves, ensuring that each system is correctly sized, compatible, and future-ready. Whether you need a feasibility study for a large public-sector project or a tailored renewable solution for your home, we support you at every stage — from initial renewable energy consultancy to project completion.

Our Process: From Concept to Results

Every system we design is built to perform – from the very first sketch to ongoing real-world monitoring. This example shows how we brought a fully optimised renewable energy system to a primary school in Carmarthen.
