What Marlec Engineering does

Marlec Engineering Co Ltd is a UK-based manufacturer founded in 1978 by John Fawkes in Rutland, specialising in small-scale off-grid renewable energy hardware. The company designs and produces the proprietary Rutland Windcharger range of micro wind turbines (including the 504, 505, 914i, 1200 Marine and Terrain, FM910-4 Furlmatic, and VertX 360 variants) at its Corby, Northants headquarters, and has since expanded into solar panels (proprietary SpectraSolar label plus distributed Ameresco, Alpex, SunWare, BP, and Longi ranges), the Solar iBoost+ PV immersion controller and its iBoost+ Buddy monitoring accessory, and the VEVA EV Charger co-developed with Em-Lite. Complementary accessories include HRDi and HRSi charge controllers, Steca, Spectra and Morningstar solar regulators, PureSine and ModiSine inverters, AGM/GEL batteries, and mounting kits.

The business operates a sales-led go-to-market combining direct e-commerce via its online shop, distribution through electrical wholesalers (notably BEW Electrical Distributors) and trade channels, marine-industry trade shows (Southampton Boat Show, METS Amsterdam), and bespoke system design delivered by an in-house Green Systems engineering team. Customers span four segments: marine and leisure vessel owners, off-grid/remote-site operators (telecoms, rail, security/CCTV), residential solar PV owners seeking to maximise self-consumption, and commercial vehicle fleet operators. Products are deployed in approximately 53 countries, with named enterprise relationships including Heatrae Sadia (Solar iBoost+ integration into Megaflo PV Ready cylinders), Komcept (government border-surveillance CCTV trailers), East Goscote Electrics/Jelson Homes (UK new-build EV charging installations), and sponsorship cases such as Jazz Turner's 2025 solo circumnavigation.

Marlec is a privately held, founder-owned UK private limited company (company number 01388473) operating with a workforce of 1–10 employees, led by Sales Director Stuart James. The company achieved carbon-neutral status (Scope 1 and 2) in 2023 and operates an on-site PV system that has generated 137MWh of renewable energy since 2011. Revenue is not publicly disclosed, there are no known funding rounds or external institutional investors, and the business model is overwhelmingly hardware sales with a small professional-services overlay for bespoke Green Systems projects.
