A Family Legacy of Quality & Care

Founded by Andreas Papadopoulos in 2008, cchellenic combines three generations of Greek craftsmanship traditions with modern British engineering standards. What began as a single van and a commitment to excellence has grown into one of Southeast England's most trusted renewable energy installers, yet we've never lost our family values.

Andreas learned precision and pride in workmanship from his grandfather, a master builder in Athens. Those same principles guide every installation we complete today. Our MCS-certified team treats every customer's home as if it were our own, bringing warmth, integrity, and meticulous attention to detail to more than 1,850 successful projects across Kent, Sussex, Surrey, and beyond.

We're proud to be British professionals with Mediterranean hearts – passionate about renewable energy, committed to quality, and dedicated to helping UK families transition to sustainable living with confidence. When you choose cchellenic, you're not just getting an installer; you're gaining a partner who genuinely cares about your home, your savings, and our shared planet.

Hear from families across Southeast England who've transformed their homes with cchellenic

"Andreas and his team were absolutely brilliant. They installed an air source heat pump in our 1930s semi and the transformation has been incredible. Our heating bills have dropped by over £100 a month, the house is warmer than ever, and the Boiler Upgrade Scheme covered most of the cost. But what really stood out was how much they cared – nothing was too much trouble, and they explained everything in plain English. Couldn't recommend cchellenic more highly."

Robert & Catherine Mills

Tunbridge Wells, Kent | Air Source Heat Pump Installation

★★★★★
"We'd been thinking about solar for years but were overwhelmed by conflicting advice. cchellenic made everything simple and transparent. They designed a system with battery storage perfectly matched to our usage, handled all the grant paperwork, and completed the installation in just two days. Six months on, we're generating more electricity than we use and our bills are practically zero. The whole experience felt personal and professional – exactly what you want from a family business."

Simon & Jenny Blackwell

Sevenoaks, Kent | Solar PV + Tesla Battery Storage

★★★★★
"As environmentally conscious parents, going renewable was important to us, but we live in a Grade II listed cottage which complicated things. cchellenic's expertise with period properties was invaluable – they worked sensitively with our listed building consent and installed a ground source heat pump that's invisible from outside. The craftsmanship was impeccable, and they clearly took pride in their work. Three years later, the system still performs perfectly, and we've cut our carbon footprint by 80%. True professionals."
