Control panels for building services and BMS contractors

BMS integrators need a panel builder who reads a points list the way they do, works to their specification without being told twice, and delivers on the date the site programme depends on. We build for building services engineers every day.

Who we work with

  • BMS system integrators
  • Mechanical and electrical contractors
  • Controls specialists
  • Consulting engineers
  • Facilities management

From points list to drawing

Send the points list and we produce the wiring diagram for approval.

Your specification or ours

We build to the integrator's spec. Where none exists, our minimum specification is published.

Standard panels, predictable

Evometrix and Gateway panels are built on one platform, so the drawings, the price and the lead time are known before you order.

Documented and tested

Test certificate and drawings in the door pocket of every panel.
