Summary

Sleeman & Hawken Limited, based in Newton Abbot, UK, is a small, holding company with an active status, having been established 67 years ago in 1958. Employing 14 people, the company holds assets worth £3,382,534, but operates from a virtual address where 122 companies are registered. It’s managed by three directors and owned by K Mason Holdings Ltd. The company regularly imports and exports machinery, boilers, and mechanical appliances, parts—with 261 months of import activity and 361 months of export activity recorded.

The company’s website showcases a specialist in diesel engine spare parts, representing brands like Deutz, FG Wilson, and Lister Petter. It caters to a wide range of industries, including construction, agriculture, and marine applications, offering both new engines and comprehensive restoration services. The site also features a news section highlighting industry updates and showcasing the company’s long-standing relationships with key suppliers.

Financially, Sleeman & Hawken Limited’s report reveals a concerning trend. Current assets have decreased by a substantial 39%, dropping to £3.4 million, while net assets have plummeted 48%, settling at £2.6 million. Bank borrowings have increased significantly, rising by 140%, reaching £140,000, and cash reserves have vanished almost entirely, falling 100% to just £640. Creditors have also increased by 58%, reaching £910,000, suggesting a potential strain on working capital. The company's small size—meeting two of three criteria for a small company—helps it remain flexible, but the sharp decline in equity and cash is a cause for concern. The report, unaudited due to its small company status, relies on director-reported data.

Despite these financial pressures, Sleeman & Hawken Limited continues to operate, leveraging its extensive network of suppliers and its reputation for technical expertise. Whether the company can navigate these challenges and sustain its long-standing presence in the diesel engine spare parts market remains to be seen.

Registered in England/Wales under the registration number 00599191, with a registered address at TQ12 4AA, Newton Abbot, Devon, Wessex House, Teign Road.
