WESTWIRE HARNESSING LIMITED
Company number 02142617 · Monitor this company
Executive summary
Westwire Harnessing Limited is a rapidly growing niche manufacturer in the aerospace and defence wire harness sector, achieving exceptional financial performance that significantly outpaces industry benchmarks. With revenue growth of 66% year-on-year to £8 million, gross margins of 50% (versus a sector norm of 30-40%), and operating margins exceeding 20%, the company has clearly benefited from strategic investment by its Indian parent SASMOS HET Technologies and favourable conditions in the defence supply chain. The planned Morocco expansion and capacity tripling position Westwire for continued growth, though sustained success will depend on managing customer concentration risk, working capital demands, and talent acquisition in a competitive regional labour market.
