Ceiba Renewables Limited

What Ceiba Renewables Limited does

Ceiba Renewables Limited is a privately held, MCS- and NICEIC-accredited solar PV, battery storage, and EV charger installation company headquartered in Glasgow, Scotland, founded in 2008 by Duncan Crosthwaite. The company designs, supplies, and installs integrated renewable energy systems for Scottish residential homeowners, commercial businesses, heritage properties, and remote or off-grid sites. Its core product set spans on-roof, in-roof, and ground-mounted solar PV arrays; battery storage using Tesla Powerwall, Hanchu ESS, and BSL-Victron configurations; and smart EV chargers from MyEnergi, Hanchu, and Tesla. Ceiba integrates best-in-class components from SunPower (Premier Partner), SolarEdge, Enphase, and Victron to optimize performance under Scotland's challenging weather and partial-shade conditions, and offers specialized heritage and off-grid installation methodologies demonstrated at the Edinburgh EIS Headquarters and the Isle of Canna.

The company operates a consultative, sales-led go-to-market model exclusively in Scotland, offering a six-step process from free initial consultation through fixed-price quote, installation (typically 1-3 days), and ongoing aftersales support. Revenue is generated primarily through one-time project fees on residential systems (£4,000-£15,000+ depending on battery size) and commercial installations, with ancillary aftersales/maintenance revenue and a finance partner referral option for customers. Ceiba's regulatory accreditation stack (MCS, NICEIC, RECC, TrustMark, Which? Trusted Trader, Living Wage Foundation) and 2026 Solar PV Installer of the Year award differentiate it, while its role as a SunPower Premier Partner and Tesla Energy Certified Installer secures premium product access.

The company is bootstrapped, operates with a small team of approximately 8 employees including naval engineers and industry specialists, and is exposed to UK solar policy, Smart Export Guarantee tariffs, and Scottish regional demand rather than global market dynamics. Its commercial moat is anchored by accreditation, complex-project execution (heritage, off-grid, island microgrid), and customer-rated trust.
