About us

ATC Systems Ltd is one of the leading Building Energy Management System (BEMS) specialists across the UK and Ireland. We design and deliver smart, energy-efficient solutions that bring buildings to life – from stand-alone control systems to fully integrated, multi-site projects.

Innovation and customer focus are at the heart of everything we do. This commitment has helped us build lasting partnerships with clients across the Healthcare, Education, Retail, Hospitality, and Industrial sectors.

Our history

ATC has over four decades of proven experience in the design, installation, and support of advanced control systems.

Established in 1978 as Automatic Temperature Controls Limited, the company initially delivered small-scale control system projects and maintenance services to local clients. In 1999, we rebranded as ATC Systems Ltd and have since grown steadily into a premier HVAC and control systems provider.

Our values

Honesty, integrity, innovation, and professionalism are at the core of everything we do. These values have shaped our reputation for quality, reliability, and technical excellence.

We are committed to working collaboratively with like-minded organisations to create sustainable growth, strengthen local communities, and promote environmentally responsible practices that support a low-carbon future.
