BLUE DIAMOND ENGINEERING LIMITED
Company number 02090988 · Monitor this company
Executive summary
Blue Diamond Engineering is experiencing severe financial deterioration, with net equity declining 95% over three years to just £53,235 and negative working capital of nearly £1M. The company is technically insolvent on a current basis, with a current ratio of 0.43:1 and minimal cash reserves of £19,010. The combination of heavy leverage (36:1 debt-to-equity), substantial finance obligations of £1.94M, a large tax liability potentially indicating HMRC arrears, and a 24% workforce reduction presents an unacceptable unsecured credit risk. Any lending would require full asset security with significant haircuts and personal guarantees.
