ENG Electrical is a specialist electrical contractor based in Hertfordshire, delivering high-performance electrical and life safety installations across some of the UK's most demanding commercial and data centre environments.
What sets ENG apart is the breadth of what can be delivered under one roof. In-house electrical design, in-house ICT infrastructure, off-site fabrication, confined space works, lighting design and control and fire and life safety systems are all delivered directly by ENG's own teams. Disciplines that most contractors of a similar size would need to subcontract out. That means fewer interfaces, tighter programmes and a single point of accountability for the client.
The business works across five core disciplines. Data centres, commercial installations, design and CAD, project management and residential. Operating across London, Hertfordshire and the South of England, with the capacity to mobilise nationally on the right projects.
Every project is managed by a dedicated project manager, coordinated through Hilti Fieldwire and backed by Alcumus SafeContractor accreditation. The same standards applied on a hyperscale data centre are applied on every job, regardless of scale.
This form is designed for serious project enquiries. The more detail you provide, the faster our team can respond with a meaningful proposal.
