Summary
Dart Sensors Ltd from Devon, UK, is a small, active company established 30 years ago. With 24 employees and £4,744,380 in assets, it’s a well-established player in its niche. The company has three directors and two owners, operating from a real address in Totnes. It regularly imports machinery, boilers, and mechanical appliances—parts, with the last import operation occurring in July 2024. Interestingly, it exports nothing, with 149 months of export activity recorded, the last in February 2025.
The company’s website highlights its focus on alcohol and formaldehyde detection, supplying components and sensors to customers worldwide. It’s a major supplier of alcohol fuel cell type sensors and components, boasting over a million sensor components and 190,000 sensors supplied in 2022. Products range from transdermal alcohol sensors to formaldehyde sensors, and even include OEM services and calibration standards. The website also mentions a focus on meeting international standards and using sensing material manufactured on site in the UK.
Financially, Dart Sensors Ltd shows some concerning trends. Cash reserves have fallen significantly by 65%, dropping to £1.3 million. Debtor values have increased by 110%, reaching £1.8 million, which could indicate challenges in collecting payments. Net assets have also decreased by 12%, to £5.1 million. While creditors have decreased by 76%, to £120,000, the drop in cash and increase in debtors suggest a potential strain on liquidity. The company’s small size (meeting two of three criteria for turnover under £10.2m, assets under £5.1m, and fewer than 50 employees) means it’s likely exempt from a full audit, so the figures are unaudited. The company’s average number of employees has also decreased by 25%, from 24 to 18. The company is using CCH software.
Registered in England/Wales under the registration number 02931435, with a registered address at TQ9 5RP, Devon, 30 Fore Street, Totnes.
