Summary

Castellex Ltd from Hertford UK is a small, active company founded nine years ago in 2015. With four employees and £125,889 in assets, it operates from a real address and is managed by two directors and one owner. The company regularly imports and exports machinery, boilers, and mechanical appliances, parts – with recent activity recorded in March for imports and September for exports.

The company’s website, Castellex, specializes in NBC (Nuclear, Biological, Chemical) and CBRN (Chemical, Biological, Radiological, Nuclear) air filtration systems. It caters to military, government facilities, families, and preppers, offering both domestic and commercial solutions. The site emphasizes comprehensive fallout and bunker protection, highlighting the importance of air quality in survival scenarios. They offer DIY-friendly kits and ship worldwide.

Financially, Castellex Ltd shows a mixed picture. Cash reserves have increased significantly, jumping 110% to £120,000, a positive sign. However, net assets decreased by 48% to -£9,200, and bank borrowings decreased by 16% to £32,000. Creditors increased by 48% to £100,000, and trade debtors dropped significantly by 97% to £1,200. The company meets the criteria for a small company, with turnover under £10.2 million, assets under £5.1 million, and fewer than 50 employees. The accounts are unaudited, likely due to its small size.

The increase in cash reserves suggests improved cash flow management, but the decrease in net assets and increase in creditors could indicate growing expenses or delayed payments. The company’s focus on specialized air filtration systems, however, suggests a niche market with potential for growth.

Registered in England/Wales under the registration number 09877853, with a registered address at SG14 1NN, England, Hertford, Hertfordshire, 16a Mimram Road.
