Summary

Cambridge Reactor Design Ltd, based in Cottenham, Cambridge, UK, is a small, active company established 34 years ago. With six employees and £4,955,191 in assets, it’s a well-established player in its niche. The company operates from a real address and is led by one director and owner. It regularly imports machinery, boilers, and mechanical appliances – parts, with the latest import occurring in July 2024. Conversely, it’s a prolific exporter, having shipped similar goods for 156 months, with the most recent shipment in February 2025.

The company specializes in designing and manufacturing innovative scientific products and solutions, particularly reactors for both batch and flow chemistry. Its website showcases a range of products, including flow reactors, batch reactors, and heating, cooling, and stirring platforms, alongside check valves and fittings. Notably, it caters to both experienced and new users in the field, offering customisation work when needed. It also has a division focused on piano restoration, a seemingly unrelated but equally prestigious venture.

Financially, Cambridge Reactor Design Ltd presents a mixed picture. Cash bank on hand has increased significantly by 52% to £2.2 million, a positive sign. However, trade debtors have decreased by 18% to £2.7 million, which could indicate slower customer payments. Creditors have also decreased by 50% to £150,000, suggesting improved debt management. Net assets have increased by 6.6% to £4.8 million, and the company’s small size (meeting two of three criteria for a small company) allows for agility. The company is exempt from an audit, so the figures are unaudited.

The increase in cash reserves is encouraging, but the decrease in debtors warrants attention. The dual focus on reactors and piano restoration, while potentially diversifying risk, could also stretch resources. Overall, Cambridge Reactor Design Ltd appears to be a stable, albeit small, company navigating the challenges of a competitive market.

Registered in England/Wales under the registration number 02550086, with a registered address at CB24 8PS, Cottenham, Cambridge, Cambridgeshire, Unit 2 Brookfield Business, Centre Twentypence Road.
