IES provides a complete end-to-end service including bespoke or repeat design, manufacture, installation, commissioning and ongoing service. We carry out all critical processes on-site – training, site safety, software and hardware design, and installation – and every job is assigned a project manager: a fully trained engineer who acts as a single point of contact throughout.

Our approach results in a seamless and rapid service with no handover issues or sub-supplier delays. Our methods ensure quality, co-ordination and cost are all kept under control and result in trouble-free lifetime design and builds for all our clients.

As approved contractors of the NICEIC and audited members of UVDB Verify we’re dedicated to working within strict Health and Safety, Environmental and Quality guidelines. We provide a safe, first-class service and ensure complete compliance with industry standards and legislation.
