About Sun Key Energy
A family-run business based in Folkestone, dedicated to helping homeowners across Kent make the switch to clean, affordable renewable energy.
Our Story
Sun Key Energy was founded with a simple mission — to make renewable energy accessible, affordable, and hassle-free for homeowners across Kent. With over 10 years of experience in the electrical and renewable energy industry, we've built a reputation for quality, reliability, and outstanding customer service.
Sonny leads every installation with the same care and attention to detail he'd give his own home. Keighley ensures every customer journey is smooth from the very first enquiry, handling all communications and administration with warmth and professionalism.
Together, we've helped hundreds of families across Folkestone, Dover, Canterbury, and the wider Kent area reduce their energy bills and carbon footprint — and we're just getting started.
