C80 Group expands with acquisition of building services consultancy

Leeds-based building consultancy business, C80 Group Ltd, has expanded its portfolio of services and geographical presence with the acquisition of Birmingham-based Stewart Associates as the latest company to join the Group. Stewarts was established in 1995 and counts the NHS and many UK Universities as some of its longstanding clients.

With 24 staff, including an experienced team of engineers and CAD designers, Stewart Associates will continue to operate from its Midlands office in partnership with C80 Group’s two companies operating from Yorkshire, C80 Solutions and YDBC Ltd. Stewart Associates’ specialist expertise in Building Services engineering will complement the services offered by C80 Group’s established team of Building Control surveyors and consultants in energy assessment, Building Compliance, consultancy, and testing.

Mark Heptonstall, CEO of C80 Group, said:

“We are very excited to welcome Stewart Associates to C80 Group. They have outstanding credentials in high quality engineering solutions for Building Services design and management, with a proven track record in delivering compliant, cost-effective, environmentally considerate and energy-efficient designs for Mechanical, Electrical and Personnel Transportation installations. C80 Group will be able to harness this valuable skillset in tandem with the other range of specialisms within the Group, serving new and existing clients across the UK. The arrival of Stewart Associates comes almost exactly one year after C80 Group’s acquisition of YDBC, which joined the C80 Group alongside C80 Solutions at the end of 2019. The collective capabilities of the Group’s three companies give us a very strong footing to expand our business on a nationwide basis.”
Steven Mason, Managing Director of Stewart Associates, said:
“Becoming part of C80 Group is a major development for Stewart Associates, enabling us to accelerate the growth of our business and develop new markets, in both regional and sectoral terms. We work extensively in various sectors including, health, education, commercial and industrial across the four corners of the UK. These sectors complement C80 Group’s traditional client base which predominantly comprises housebuilders, contractors, developers, and architects. With a shared belief in the importance of sustainable solutions, the Group’s combined strengths and market presence offer enormous potential in the coming years.”

C80 Group’s expertise encompasses all aspects of Building Regulations, Building Control and environmental performance, including energy assessment, BREEAM, air tightness, sound testing, environmental noise and thermal modelling. Its services support construction across both the commercial and domestic sectors.
