Electrical installations to standard

We deliver high- and low-voltage wiring, distribution boards and intelligent controls for commercial and residential projects.

We cover the entire electrical part of a construction project — from laying cables during the shell stage through fitting distribution boards to inspections and handover. We work with a certified inspection technician and all installations comply with the applicable standards.

  • Low-voltage systems (data, intruder alarm, fire alarm, CCTV)
  • Distribution boards and their installation
  • Lightning protection and earthing
  • LED lighting and controls
  • Smart home and KNX solutions
  • Initial and periodic inspection

Frequently asked questions

Do you carry out inspections without doing the installation?

Yes, we provide initial and periodic professional inspections and tests for buildings we did not construct.

What is the difference between high and low voltage?

High voltage is the usual 230/400 V wiring for appliances and lighting. Low voltage covers data, telephone, camera, security and fire systems with voltages up to 50 V.
