When something needs attention, our teams are ready to respond. Through our mobile engineering fleet and 24/7 support capability, we provide reactive maintenance across mechanical, electrical and building services systems, helping minimise disruption and keep buildings operating safely and efficiently.

Good maintenance is about preventing problems before they happen. We provide tailored planned and preventative maintenance programmes designed around the needs of each building, helping extend equipment life, reduce outages and maintain long-term performance.

Our experienced helpdesk provides a single point of contact for ongoing building support. From managing defects and arranging engineer visits to coordinating servicing and remedial works, we help clients get the right support quickly and keep issues moving towards resolution.

Keeping buildings compliant requires regular inspection, testing and action. Our teams support clients with services that include fixed-wire inspections, PAT testing, emergency lighting certification, fire alarm servicing and associated remedial works, with experience across large and varied estates.

Our involvement can continue seamlessly beyond project completion. By engaging with project teams before handover, our aftercare specialists build an understanding of the building and its systems, helping manage defects, identify recurring issues and provide continuity during the transition into operation.

Not every requirement needs a major project team. ESG Prime can mobilise quickly for smaller works and multi-site programmes, including equipment replacement, upgrades, retrofit works and minor fit-out projects, providing clients with an experienced team for ongoing improvements across their buildings and estates.
