About
Established in 1979, we’ve expanded our business and expert services whilst retaining the same family-run ethos our founders instilled.
A family-run business and your expert, trusted partner.
Your Trusted Partner for Mechanical, Electrical, and Construction Services
At ETS, we know what matters most to our clients: clear communication, dependable delivery, and a job done right, first time. That’s exactly what we’ve built our reputation on.
Whether you need temporary power for a live construction site or a full refurbishment and M&E package, we make it simple to get moving, with one experienced team who brings everything together.
A Family Business Built on Practical Expertise
ETS Group of Companies is made up of ETS (SW) Ltd, ETS (FM) Ltd, ETS (EPE) Ltd, and ETS Cymru Ltd, operating out of our Bristol headquarters and supporting clients across the South West, Wales, and the wider UK.
We’re proud to be a family-run business, with strong roots and strong values. Founded in 1979 by Des Derrick and Dave Cole, ETS was built on trust, craft, and a commitment to adapting with the times, and we’ve stayed true to that approach ever since.
From Humble Beginnings to High-Profile Projects
After nearly a decade of steady growth and early success, ETS secured our first major contract in 1987 with Tesco Stores, followed soon after by the Aylesbury Shopping Centre for Henry Boot and a significant installation project at Tidworth Army Barracks.
As the company’s reputation spread, demand increased, particularly across Wales. In 1993, we opened a Cardiff office, leading to high-profile projects like the refurbishment of the Museum of Wales and the landmark Millennium Stadium, home of Welsh rugby.
Leadership That Stays in the Family
In 2010, company leadership passed to the next generation. Mark Cole, son of co-founder Dave Cole, became Managing Director. He was joined by:
Sam Cole, Company Secretary and Head of Accounts
Mark Herbert, Director of the Temporary Electrics Division (until 2018)
Nathan Cole, who joined as Operations Director in 2015
Together, they’ve steered ETS into a new era of professionalism, growth, and innovation, all while keeping the close-knit, family values the company was built on.
Today, our senior management team includes a group of highly experienced professionals, many with over 20 years of service at ETS, who bring deep expertise in electrical contracting, construction services, and project management.
Growing Stronger — Year After Year
ETS now employs over 35 skilled professionals, delivering everything from temporary site services and electrical installations to mechanical engineering and full turnkey fit-outs for commercial, industrial, and public sector clients.
We’ve built long-standing relationships with national brands, contractors, and local authorities, not through flashy sales tactics, but by doing what we say, when we say it, and doing it well.
In 2019, we proudly celebrated 40 years of service, and our story is still being written.
