Domestic installation inspection: procedure and safety certificate

Safety

Why the house installation inspection is important

Faulty electrical installations can cause accidents or fires.

Electricity is practical, but it can be dangerous if handled improperly or if it flows through faulty installations and devices. Responsible owners must therefore have their electrical installations inspected regularly.

Roles and responsibilities

Who has which task during the check

Owners, inspection body, electrical installation company and network operator have clearly separated roles.

Owners

Owners remain responsible for the safety of their electrical installation. They commission the inspection, bear the costs and submit the safety certificate on time.

Process

The installation inspection step by step

From the request to the safety certificate.

This is how the periodic inspection of your domestic installation works.

Periodic request 01

Written request received

Property owners receive a written request from the grid operator for the periodic inspection and for submission of the safety certificate with the measurement and test report.

Mandate to the inspection body 02

Commission an independent inspection company

Owners commission an independent inspection body. It must not have been involved in the planning, construction, modification or maintenance of the installations to be inspected.

Inspection 03

Have inspection carried out

The inspection body checks all installations in the building in accordance with the applicable legal provisions and standards. If everything meets the requirements, owners receive the safety certificate with measurement and inspection report.

Rectification of defects 04

Rectify defects within the deadline

If the inspection body identifies defects, it prepares a report or a list of defects. Owners commission a licensed electrical installation company to remedy them. The defects must be rectified within the specified deadline.

Electrical safety certificate 05

Have a safety certificate issued

If the installations are free of defects, the inspection body issues the safety certificate with the measurement and test report and hands it over to the owners.

Submission 06

Submit and retain proof

Owners are responsible for ensuring that the grid operator receives the safety certificate on time. The safety certificate must be kept at least until the next inspection and presented on request.

Deadlines and costs

What you should know before the inspection

The focus is on the inspection period, costs and responsibility.

The safety certificate must be renewed after the specified inspection period has expired. Depending on the installation, this period is 1, 3, 5, 10 or 20 years. The costs of the inspection and any costs for rectifying defects are borne by the owners of the installation.
