What Wilson Power Solutions does

Wilson Power Solutions is a third-generation, family-owned UK transformer manufacturer founded in 1946, headquartered in Leeds with manufacturing operations in Chennai, India and a rental business in Dubai. The company designs and builds power transformers (5MVA to 300MVA, up to 400kV) and distribution transformers (up to 5MVA), with a particular focus on amorphous metal core technology that delivers up to 27% lower combined losses than EU Tier 2 Ecodesign standards. Its registered product range includes the Wilson e2/e3/e4 amorphous series, the Wilson T2 Ecotrans Tier 2 line, the Wilson d2 iDNO Unit Type, and packaged substations/ancillaries, sold via direct field sales with regional UK sales managers and specification support, complemented by an exclusive Toshiba DNO partnership and a strategic collaboration with Tesla for Battery Energy Storage Systems.

The company serves a diversified enterprise customer base across Battery Energy Storage, Data Centres (AWS), DNO/iDNO/ICP network operators, Renewable Energy, EV charging (GRIDSERVE), Industrial/Manufacturing (Rolls-Royce), Retail (Tesco), Food & Beverage (Arla, Oatly, British Sugar), Healthcare, Education, Water, and Transport (Wimbledon). Revenue is generated through one-time bespoke and standardised transformer sales priced per project based on rating, voltage, efficiency class, cooling type, and accessories, with multi-year contract cadence typical for infrastructure projects. Wilson holds ISO 9001/14001/45001 certifications, manufactures to IEC 60076, and reports £113.6 million in revenue for its most recent reporting year (Sunday Times 100 2026), with 66.67% three-year annual sales growth and recognition in both the Sunday Times 100 and Financial Times 1000 Europe fastest-growing companies lists.
