Design, installation, and maintenance in heating, cooling, ventilation & water — delivered with innovation and care.
At RSG, we provide innovative, reliable, and compliant solutions across heating, cooling, ventilation, and water — from full system design and installation to ongoing maintenance and compliance.
Our focus is on safeguarding the built environment while making it safer, more efficient, and more comfortable for the people who live, work, and visit.
By combining technical expertise, customer focus, and the latest technologies, we keep systems performing at their best — creating sustainable environments for end-users and peace of mind for our clients.
From offices to industrial plants, reliable heating isn’t optional—it’s business-critical. RSG designs, installs, and maintains heating systems that deliver consistent performance with reduced running costs. Our engineers are trusted across Scotland for their expertise in boilers, heat pumps, CHP units, and distribution pipework.
With planned maintenance and lifecycle replacement, we help clients avoid costly breakdowns, extend equipment life, and cut carbon emissions. It’s why healthcare, education, and commercial clients across Scotland rely on us to keep their buildings warm, safe, and fully compliant—whatever the season.
From data centres demanding precision to workplaces needing comfort control, RSG delivers cooling systems that never miss a beat. We cover chilled water systems, VRF/VRV, and industrial process cooling—designed for resilience and efficiency.
Our engineers maintain systems to manufacturer and industry standards, optimising performance while ensuring F-Gas compliance. And when issues do arise, our local teams are on hand to respond quickly, minimising disruption. With RSG, you get cooling solutions that are efficient, reliable, and backed by responsive Scottish support.
Clean air isn’t just a compliance requirement—it’s the foundation of healthier, more productive environments. At RSG, we design and maintain ventilation systems that safeguard occupant wellbeing while meeting CIBSE and SFG20 standards.
From air handling units and ductwork to specialist extract systems, we ensure airflow is safe, balanced, and efficient. Regular inspections prevent hidden risks, protect building performance, and ensure energy isn’t wasted. The result? Safer spaces, happier people, and systems you can depend on.
Water systems need more than compliance—they need careful integration with your wider mechanical plant. That’s where RSG stands apart. Alongside our heating and cooling expertise, we deliver water safety services including Legionella risk assessments (ACoP L8, HSG274), BG29/50 closed-system sampling, and valve testing.
For clients across healthcare, education, and FM, our approach keeps water systems safe, efficient, and fully audit-ready. By embedding water compliance into your broader maintenance plan, we make safety seamless—protecting both your people and your reputation.
