What Quartzelec does
Quartzelec Ltd is a UK-headquartered electrical engineering services company specialising in rotating electrical machines (AC/DC motors and generators up to 660MW) and HV/LV electrical infrastructure. Operating since circa 1920 and wholly owned by Quartzinvest Limited, the business is organised around two service lines — Contracting Services (HV/LV construction, utility works, building services) and Rotating Machines (design engineering, repair/rewind/refurbishment, condition monitoring) — supported by wholly-owned subsidiaries Quartzcoil (coil and winding manufacture up to 6m length), Quartzteq GmbH (proprietary LIFEVIEW condition monitoring brand) and TS Metals (welding and fabrication).
The company's product portfolio centres on the LIFEVIEW suite of permanent online partial discharge analysers (PDA II, PDA III launched February 2026, Mobile) with proprietary QCC12/QCC17 sensors, complemented by AVR/Excitation systems, Rosenberry Hub motor starters, Rotoguard protection devices, a full range of HV terminal boxes, and replacement spares for rotating machines. Underlying technology rests on state-of-the-art coil manufacturing equipment (loop winder, Roebel bar assembly, coil forming), Ex-certified workshop capability in Aberdeen, Swansea, Grimsby and Sheffield, and a dense stack of sector accreditations (ISO 9001/14001/45001, Achilles UVDB Verify, RISQS, NERS, IECEx, FPAL Verified).
Quartzelec makes money primarily through project-based professional services and multi-year framework agreements with large enterprise and government customers across power generation, oil and gas, metals and mining, marine and defence, utilities, rail, healthcare, education and commercial real estate. Named anchor customers include SSE (4-year framework, 40+ generators), Anglian Water, Scottish Power Energy Networks, BP, Essar Stanlow, NHS Greater Glasgow and Clyde, Royal Navy, Airbus, Tata Steel and First ScotRail. Pricing is bespoke with custom quotes per project; revenue is supplemented by hardware sales (LIFEVIEW systems, terminal boxes, spares, coils), approved service partnerships (e.g., Grundfos UK warranty) and recurring maintenance contracts. FY2025 turnover reached £93.8m with £10.2m profit before tax, supported by a record £99.4m order book.
