En-Gen Diesel

What En-Gen Diesel does

En-Gen Diesel Products Limited is a privately-held UK distributor, authorised dealer, and technical service provider for diesel and gas engines, generator sets, and related spare parts, headquartered in Great Yarmouth, Norfolk. Founded in June 2017 by directors Nigel Haylett and Anthony Hills, the company serves five end-markets — Marine (leisure, commercial and industrial), Oil & Gas (including Zone II / Rig Safe hazardous-environment applications), Industrial, Power Generation, and Materials Handling — across the UK and globally via a freight-forwarding partner network. It holds authorised-dealer positions for multiple premium OEMs including Himoinsa (a Yanmar company), Baudouin, PowerHeat (Carlor/ZeroStart), Marapco, Yanmar, Kawasaki, and WaterMota/JMP Pumps, alongside sourcing access to major brands such as Caterpillar, Detroit Diesel, Volvo Penta, Perkins, Scania and John Deere.

The company's core technology and capability stack spans three pillars: parts and equipment supply (engine and generator spares, air starters, remanufactured parts, filtration, lubricants, pumps, surplus/used equipment, generator sets from 7 kVA to 2 MW including soundproof, container, open-skid and trailer-mounted configurations); in-house and on-site technical services including engine rebuild and repair by factory-trained engineers, dynamometer testing up to 2000 bhp, fuel-injection spares and test/repair for Delphi/Continental/Denso/Bosch/Stanadyne/Woodward equipment, hydraulic design/manufacturing/repair, precision CNC machining in stainless steel, aluminium, nylon, brass and plastic, and oil analysis for predictive maintenance; and direct e-commerce via the engendiesel-shop.com storefront for PowerHeat and JMP Pumps parts. Operations are conducted from Unit 15, Faraday Road, Gapton Hall Industrial Estate (NR31 0NF), with the engine service and rebuild centre opened in January 2020.

The business model combines hardware sales (engines, generator sets, parts) with professional services revenue (rebuilds, dyno testing, fuel injection, hydraulics, machining, oil analysis), distributed through a hybrid of direct enterprise sales with dedicated departments for General, Parts, Service, Engine Sales and Generator Sales, an authorised-dealer channel for premium OEMs, and an online parts shop. Pricing is predominantly quote-based across all product and service lines, with generator unit pricing structured around kVA rating and specification tier. The customer base is anchored in enterprise accounts across Oil & Gas, Marine and Materials Handling with named contracts (e.g., an offshore supply company engine rebuild and a pilot-boat operator two-engine supply), supplemented by SMB and individual buyers via the online shop. There is no external funding, parent company, or subsidiary structure; the company is entirely founder-owned and operates with 1-10 employees.
