Our History, Values & Partners


From humble beginnings.

Initially formed back in 1978 as Automatic Temperature Controls, the company provided small scale projects, service and maintenance to local clients. Under diligent management succession and re-branded in 1999 as ATC Systems Ltd the company has grown steadily to become one of the leading BEMS controls companies throughout UK and Ireland with offices in Newtownabbey, Derry/Londonderry and Dublin.

Customer focus and innovative, energy efficient design is at the heart of the company. This approach has allowed us to build strong relationships with both customers and market leading manufacturers. We are proud to support major Healthcare Trusts, Education, Retail, Hospitality and Industrial sectors.


Honesty, Integrity, Innovation and Professionalism.

ATC Systems Ltd have built an enviable reputation based on these core values. With strong corporate and social responsibilities we believe in working together with other like minded companies to create business opportunities, boost local communities and ensure sustained growth for future generations.
