What Optimum Heating does
Optimum Heating (legal name Optimum Heating and Electrical) is a Barnstaple, Devon-based commercial heating, electrical, and renewable-energy contractor founded in 1992, serving customers primarily across South West England with an 11-50 employee headcount. The company designs, installs, commissions, and maintains commercial heating systems spanning gas, oil, biomass, air-source heat pumps, ground-source heat pumps, photovoltaic generation, and battery storage, alongside BMS integration, electrical contracting, and catering equipment services. It holds a deep stack of UK trade accreditations (Gas Safe, NICEIC, HETAS, OFTEC, NAPIT, SafeContractor, WRAS, CP42) and operates an in-house qualified engineering team backed by a 24/7 service desk.
Revenue is generated through three reinforcing streams: project-based contracting for installation and commissioning of heating, electrical, and renewable systems; planned and reactive maintenance contracts on the installed base (including BMS); and equipment distribution margins earned via exclusive and non-exclusive agreements with manufacturers. The company holds exclusive South UK distributorship for KWB biomass boilers and acts as a regional distributor for Maxa air-source heat pumps, Volta/Ecoforest ground-source heat pumps, and SolarEdge PV/battery products, giving it both installation and channel-leverage optionality in the South UK market.
Customer engagements span hospitality, manufacturing, education, healthcare, agriculture, professional services, and residential development, with named references including housing developers (Barratt London district heating projects), creative agencies (Bray Leino), and country-house hospitality venues (High Bullen). The business is privately held with no disclosed funding rounds, M&A activity, or leadership transitions in the evidence base, positioning it as a bootstrapped, mature SME that has layered renewable-energy distribution onto a traditional commercial contracting foundation.
