Summary

Stm Engineering Ltd from Great Yarmouth UK: a small, holding company with an active status, was founded 29 years ago. Employing 31 people and holding £4,489,088 in assets, it operates from a real address and is managed by four directors and one owner. The company regularly imports machinery, boilers, and mechanical appliances, parts, with 29 months of import activity recorded, and exports similar items, with 16 months of export activity.

Stm Engineering Ltd specializes in marine diesel engineering, CNC machine shop services, fabrication, and welding, alongside diesel engine repairs and maintenance. The company serves shipping, oil and gas, chemical, power generation, and civil engineering sectors, operating from workshops in Great Yarmouth and Middlesbrough. It also acts as an agent for Man Engines and Components Corrosion BV Rock Oil, and boasts a strong reputation, evidenced by positive customer feedback.

Financially, Stm Engineering Ltd’s recent performance shows some concerning trends. While cash reserves increased by 9.8% to £2.8 million, net assets plummeted 99.99% to just £7,700—a dramatic shift. Bank borrowings decreased by 78%, reaching £270,000, and trade debtors decreased by 27%. Property plant equipment decreased by 1.6% to £1.6 million. The company’s small size (meeting two of three conditions for being a small company) allows for flexibility, but the sharp decline in equity raises questions about its financial health. The lack of an auditor is consistent with its status as a small company, meaning the financial statements are unaudited. It seems like the company has been struggling to maintain its equity, and it's important to monitor its performance closely.

Registered in England/Wales under the registration number 03119560, with a registered address at NR31 0NQ, Great Yarmouth, Norfolk, Masco House Shuttleworth Close, Gapton Hall Industrial Estate.
