About Us

ESG are a leader in the building services market, underpinned by our strong brand and long trading history. Our core values are intrinsic in a continued drive for engineering excellence; being a ‘Smart, Responsible, Trusted partner of choice, who is Focused and Passionate about every project we deliver.

In 1975 our Chairman John Sampson created the Essex Services Group, a family business which provided building services installation to the retail and commercial fit-out sectors. Today, as ESG, it generates an annual turnover of more than £100 million with average MEP project values of £30 million yet retains the same family values it always has done. ESG operates across a diverse range of construction markets including high-spec residential, commercial fit-out, data centre delivery, modular engineering and the fast-paced retail and specialist fit-out sectors.

To ensure we provide the right solution for your project, the group is supported further by our specialist fit-out and aftercare team at ESG Prime. Their experience is founded upon decades within a reactive retail and commercial fit-out marketplace, where minimal lead-times and short construction periods require an expert team. ESG Prime provide facilities management and a comprehensive range of aftercare services, delivered by our mobile engineering fleet.

Our people are driven by innovation and have a reputation for combining engineering excellence with years of experience and grounding. Through steady growth and solid client relationships, we show an ambition to lead, not just to follow and it is this focused determination, passion and smart approach that makes us the right choice for your building services delivery.
