About us
Controls and electrical engineers for the modern London estate
We keep commercial buildings comfortable, compliant and efficient - from City headquarters to schools, hospitals and data halls.
Built by engineers, run for occupiers
EcoNex is a newly combined company, but the team behind it brings together more than 75 years of collective industry experience. That depth is why we can work confidently in commercial buildings, critical infrastructure and occupied environments where there is no room for guesswork.
We provide a complete end-to-end service: our designers write the control strategy, our workshop builds the panels, our electricians install the power, our commissioning engineers prove every point, and our maintenance team keeps it accurate for the years that follow.
One accountable team, from concept through to long-term support. That single line of responsibility is why clients keep us on their estates long after handover.

How we work
Open by default
Open protocol systems the client owns. No proprietary lock-in, ever.
Energy first
Every strategy is written to cut consumption, not just satisfy a spec.
One team
Design, installation, electrical and commissioning under a single point of contact.
Live buildings
Phased, out-of-hours delivery so occupiers never lose heating or cooling.
