About Us

Combined Services is a dynamic, long established and customer focused Building Energy Management System (BMS) specialist company, offering complete turnkey solutions from initial system design, to service and maintenance of installed systems.

Since our inception in 1992 Combined Services have seen organic and steady growth and although remaining completely vendor agnostic, are an approved system house for a number of leading BEMS manufactures, allowing us to select best fit products for each individual project.

As well as offering complete turnkey system projects to our diverse and expanding client base within the Build Environment, we are a leading and trusted supplier of HVAC control panels within the industry, to other BEMS specialist companies. Our dedicated retail BEMS team is a trusted and time proven partner of some of the UK’s largest supermarket chains.

Through utilizing our skilled in-house staff, sub-contractors and well established supply chain we can integrate our systems with a wide range of 3rd party systems including lighting, security, access and home automation applications. We also integrate open protocols including BACnet, LON, M-BUS, Modbus and KNX.
