Addison Project

Addison Project is an award-winning engineering, design, project management and EPCM organisation delivering complex capital projects and engineering services across the energy, chemicals, process manufacturing, infrastructure and utilities sectors.

Established in 1997 from the former ICI engineering division, we have built a reputation for providing pragmatic, safe and value-driven engineering solutions while acting as a trusted extension of our clients' teams.

With offices in Teesside, Cheshire, Lancashire and Harlow, we provide nationwide support through a team of multi-discipline engineers, designers, project managers and construction professionals. Our in-house capability spans process, mechanical, piping, civil & structural, electrical, control & instrumentation engineering, alongside project controls, procurement support, CDM, construction management and programme delivery services. We support projects from concept development, feasibility studies and FEL/FEED through to detailed design, procurement, construction, commissioning and handover.

Our experience ranges from small plant modifications and engineering resource support through to major brownfield and greenfield capital projects exceeding £100 million in value. We work across highly regulated and safety-critical environments, helping clients improve asset performance, increase capacity, enhance sustainability, maintain compliance and deliver their net-zero ambitions.

At the heart of Addison Project is a collaborative approach. We pride ourselves on developing long-term partnerships, integrating seamlessly with client teams and providing practical engineering solutions that add value throughout the project lifecycle. Safety remains central to everything we do, underpinned by ISO 9001 accreditation and a long-standing commitment to engineering out risk through safe, robust design and project execution.
