United by purpose.
We’re the trusted partner for the UK construction industry, delivering pioneering engineering and technology solutions that make buildings perform better.
From offsite manufacturing to advanced digital design, our integrated approach ensures resilient, sustainable MEP systems, built with precision, improved quality, and a better experience for users and the environment.
But we’re not ones to stand still. Today, we’re driven by a bold spirit of innovation and a shared purpose: to create smarter, more sustainable spaces where people and communities thrive.
What we do
We partner with Tier One contractors and end users to deliver complex and considerate engineering services to some of the UK’s largest and most exciting builds.
With a 64-year heritage, we specialise in the design, fabrication, and installation of building services and infrastructure solutions across a wide range of sectors. Born from a proud heritage of engineering excellence. SES has always valued craftsmanship and precision.
How we work
From pioneering digital tools to embracing modern methods of construction, our integrated approach blends technical mastery with advanced design and digitalisation.
With a growing network of offsite facilities, we deliver resilient MEP solutions that are not only precise and high-performing, but also environmentally attuned and user-focused.
Our approach has evolved beyond traditional subcontractor-customer relationships to forge long-term partnerships which emphasise early engagement, transparency, and delivering strategic visions.
At the heart of everything SES does lies our purpose:
Reimagining places for people to thrive
Our transformation extends beyond mere growth. In line with our purpose, we’re reimagining the future of technology in construction.
“Through sustained investment in advanced digital engineering, smart technologies and offsite manufacturing, combined with striving for excellence in delivery, we are positioning ourselves to become the most profitable and sustainable engineering and technology business in UK construction.”
