Summary
Sl Engineering Ltd, based in Sleaford, UK, is a well-established family business with a 51-year history and an active trading status. Employing 70 people and holding assets valued at £3,151,633, the company operates from a real address and is managed by six directors and four owners. It’s a regular importer of machinery, boilers, and mechanical appliances, parts, with 15 months of import activity, and a regular exporter with 90 months of export activity.
The company’s website details a full-service operation specializing in the manufacture of rigid tube assemblies, tubular manifolds, and precision machined components. It caters to a diverse range of sectors, including aerospace, civil military, engine airframe, power generation, and transportation. They provide CNC tube manipulation, welding, brazing, and NDT testing—offering a comprehensive suite of capabilities. The website also highlights case studies, news updates, and a vacancies section, showcasing its commitment to innovation and growth.
Financially, Sl Engineering Ltd presents a mixed picture. Current assets increased by 12% to £3,200,000, while net assets increased by 55% to £1,200,000. Bank borrowings decreased by 26% to £300,000, and cash reserves decreased by 86% to £6,200. Creditors increased by 19% to £720,000. The company’s small size—meeting two of three criteria for turnover under £10.2m, assets under £5.1m, and fewer than 50 employees—allows for flexibility, but the drop in cash reserves is something to keep an eye on. The company’s unaudited financial statements, as a small company, are not independently verified.
The company’s long history and family ownership suggest stability, but the fluctuating financial data indicates potential challenges. The company’s focus on high-performance products and specialized manufacturing, however, positions it well for continued success in demanding industries.
The company operates in Processing & manufacturing → Metal products → Other products n.e.c..
Registered in England/Wales under the registration number 01147082, with a registered address at NG34 0HJ, England, Sleaford, Lincolnshire, Sl Engineering Ltd Temple Road, Aslackby.
