J Ll Leach has been a trusted partner to Midlands industry since 1936. We understand that in Derby’s high-precision environments, compressed air is not just a utility—it is a mission-critical component of your production process. Whether you are supporting a major aerospace supply chain or a local engineering workshop, our team provides the rapid-response servicing and technical expertise required to keep your operations moving.
Derby is home to some of the most prestigious names in engineering, particularly within the aerospace, rail, and automotive sectors. From the massive production facilities at Sinfin and Raynesway to the diverse engineering firms on the Wyvern Business Park and Pride Park, reliable compressed air is the heartbeat of the city’s economy.
In these high-spec environments, any compromise in air quality or pressure can lead to catastrophic component failure, expensive rework, or failed quality audits. We specialise in delivering high-uptime, high-purity solutions for Derby’s critical industries:
While compressed air is our heritage, J Ll Leach offers a “whole factory” approach to industrial utilities. We are fluid power specialists, capable of managing all your piped systems to improve efficiency and reduce total cost of ownership.
For Derby’s advanced materials and pharmaceutical sectors, we provide On-Site Nitrogen Generation. By switching from delivered cylinders to an Atlas Copco nitrogen generator, businesses can save up to 80% on gas costs while eliminating the logistical headaches of supplier deliveries.

We are also authorised distributors for Spirax Sarco, providing expert design and maintenance for Steam Systems used in process heating and sterilisation. Our engineers can survey your steam traps and control valves to ensure you aren’t losing money through thermal inefficiency.
To support your sustainability goals, we offer comprehensive Energy Audits and Heat Recovery Systems. We can capture up to 94% of the waste heat from your compressor and repurpose it for space or water heating, significantly lowering your carbon footprint and helping you comply with ESOS or ISO 50001 requirements.
