As our clients' needs grew, so did we. We expanded into the water industry in 1994, moved into specialist pharmaceutical projects in 2008, and in 2013 established our own electrical installation capability to meet strict WIMES standards and reduce our reliance on subcontractors. In 2022 we went further, investing in in-house plastic ductwork manufacturing and control panel production — bringing greater control over programme, quality, and adaptability to better serve the people who trust us with their projects.

From two founders to nearly 100 people. From a single specialism to a genuinely multi-disciplinary contractor, working nationwide across pharmaceuticals, logistics, utilities, high-end commercial and residential, and service and maintenance, with a turnover of £15m.

Over 85% of our clients return within 12 months. That figure says more about who we are than any accreditation.

What makes ATS different is the ATS Way. We combine the care and adaptability of a close-knit team with the structure and capability of a much larger business. Our people stay — the average length of service is over five years — because they are valued, and that experience translates directly into consistency and quality for our clients. Alongside investment in our people, we stay at the forefront of technology and hold accreditations including ISO 9001 and ISO 14001, ensuring every project is delivered responsibly, ethically, and safely.
