What PlugMeIn does

PlugMeIn (legal entity: Plug Me In (Solar) Limited, Companies House number 07578432) is a UK-based commercial clean energy installer founded in 2011 and operating as a wholly-owned subsidiary of Calisen Group (Holdings) Limited since its 2022 acquisition of parent Environmental Energies Limited. The company designs, installs, and maintains commercial-scale solar PV systems, battery storage, and EV charging infrastructure for UK businesses, with named enterprise customers across agriculture (Barfoots Farm, Slate Barn Farm), public sector (NHS Lynfield Mount Hospital, London School of Economics), logistics (Cummins Logistics), media (BBC Essex), commercial office (Fruitful Office), and SMB verticals. Its technology stack integrates third-party inverters and batteries (SolarEdge, Tesla, Solax, Sun Synk, Solis), a Meteocontrol weather-forecasting integration for solar yield optimisation, and proprietary smart monitoring, load-balancing, and power management software for EV charging depots.

The business model combines upfront installation revenue (traditional purchase or capital-funded PPA, where PlugMeIn funds the system and customers pay per kWh consumed) with recurring service and maintenance contracts, and emerging annuity income from National Grid balancing services via customer battery assets. The firm holds MCS, OZEV, NICEIC, TrustMark, RECC, NFU, and CHAS accreditations that gate access to UK government grants and public sector procurement, including appointment to the £660M LHC Procurement Group Retrofit and Decarbonisation (N9) Framework. Go-to-market is hybrid: direct enterprise field sales for large commercial, agricultural, and public sector clients, an inside-sales motion for mid-market and SMB inbound quote requests, and a dedicated 'Plug me in Fleet' sub-brand targeting commercial fleet operators. Operations are delivered through in-house engineers with national mainland UK coverage, a UK-based contact centre, and shared back-office functions provided by parent Calisen Group.
