Rainham Group

Rainham Group was established in 1988 as a specialist provider of commercial refrigeration, air conditioning, and heating solutions. Our team of fully qualified and registered engineers delivers installation, service, and maintenance across the UK, prioritising engineering excellence and technical competence. We acquired Air Environment Limited in 2005 to expand our expertise in ductwork and ventilation, enabling a comprehensive in-house service. Our operations leverage modern information and communication technology to enhance performance and client satisfaction. The personal touch remains central to our business philosophy, underpinning our reputation for quality and service. We offer 24/7 reactive support, with engineers registered under Refcom and Gas Safe standards.

Our services span design, sales, installation, and maintenance of systems ranging from small split units to large-scale building refurbishments. Tailored maintenance agreements and compliance-focused solutions, including water risk assessments and TR19-compliant ductwork cleaning, address diverse client needs. Gas safety certifications and adherence to health and safety regulations ensure reliability and legal compliance. With decades of experience, we combine technical expertise, industry-leading partnerships, and a commitment to innovation to deliver trusted solutions for commercial clients nationwide.
