Our story

How we got here.

Circle Energy launched in 2026, but the thinking behind it had been building for a while. Working across aerospace and maritime, Greg kept noticing the same thing in the solar industry: systems installed too quickly, signed off too loosely, and left with no one accountable once the scaffolding came down. For something meant to sit on a roof for twenty-five years, that didn't sit right.

At the same time, the demand was clear. New-build developers increasingly need solar as standard — driven by the Future Homes Standard and tightening building regulations — and they need a partner who can design it in properly at build stage, deliver it across a whole development, and still be there afterwards. New-build is simply where solar is done best: designed in early rather than bolted on later, and repeatable across every plot.

So Circle Energy was built to be that partner — one accountable team under a single contract, from early-stage design through installation, compliance and aftercare. No chain of subcontractors, no gaps in the paperwork, and real support after handover rather than a number that stops answering.

Underneath it is a straightforward belief: clean energy should do two jobs at once. Help build a more sustainable future for the next generation, and give people a little control back. In an economy that asks more of everyone every year, a well-designed solar system takes one household cost and puts it back in their own hands.

Leadership

The people behind the work.

Greg Dally

Co-Founder & Director

Circle Energy was co-founded by Greg Dally, an engineer whose career spans more than twelve years across aerospace and maritime. He started out as an aircraft engineer, working on the overhaul of commercial aircraft engines, before a stint at sea as an engineer aboard superyachts. More recently he's worked back in aviation — in inspection technology and aircraft asset consultancy, managing assets on behalf of clients and keeping airworthiness compliance predictable and fairly costed.

Solar might sound like a departure, but for Greg it's anything but. The things that keep an aircraft engine safe in the air are the same things that make a solar system worth trusting on a roof — careful maintenance, real quality control, a safety-first way of working, and documentation you can actually stand behind.

That's what Circle Energy is built on: every system engineered properly, installed to specification, and backed by paperwork that stands up to scrutiny.

And underneath it all is something simpler — wanting to help leave a cleaner planet for the next generation, and to give people energy they can depend on and afford, putting at least one part of the household bills back in their own hands.

Why Circle

End-to-end delivery under a single contract — helping accelerate clean energy across new housing and supporting Wales' decarbonisation targets.
