30 years of E-CHECK – only from your electrical guild contractor
The recognised safety inspection from a qualified electrical guild contractor.

Peace of mind with inspected electrics

The E-CHECK provides clarity and safety.

Modern life places far greater demands on electrical installations than in the past. Higher loads, older wiring or subsequent alterations can create unnoticed weaknesses. With the E-CHECK, we professionally inspect the condition of your electrical installation.

Identify risks early

Wear, damage and safety-related defects are checked systematically.

Document the results

You receive an inspection report with the results and clear guidance.

Make safety visible

Following a successful inspection, the E-CHECK label confirms the proper condition.

What is inspected?

  • Distribution board, circuits and protective devices
  • Wiring, sockets and switches
  • Residual-current protective devices (RCDs)
  • Protective measures of the electrical installation
  • Subsequent alterations to the installation

When is an E-CHECK advisable?

  • For older installations or those not inspected for a long time
  • After purchasing or moving into a property
  • Following renovations or extensions
  • When protective devices trip frequently
  • As a regular safety precaution
