About Us
Building a network of sustainability champions
We're a private, fully accredited renewable energy installer with a single goal: deliver premium clean-energy systems that genuinely change how UK homes and businesses use power.
Our Story
Engineering-led, customer-first
Gwella Group was founded by engineers who were frustrated with rushed, low-quality renewable installations across the UK market. We built a different kind of company: design-led, properly accredited, and fully committed to long-term customer relationships.
Every system we install is privately funded by the customer — so the only thing we have to sell is genuine quality and measurable performance. That's how we like it.
Today we operate from St Asaph in North Wales, with installation teams covering the whole of England and Wales.
