Inspection & YDE Certificates

Comprehensive inspection of your electrical installation, preparation of the necessary plans, and issuance of the Installer's Declaration of Compliance for residential, commercial, and other premises.

What is YDE?

The Installer's Responsible Declaration (YDE) is the official document in which the qualified electrician declares—following inspection and measurements—that the electrical installation is safe and fit for use.
The YDE is accompanied by the required inspection protocols and electrical diagrams and is submitted to DEDDIE in accordance with the prescribed procedure.

When is a YDE (Certificate of Electrical Installation) required?

New electricity connection

For connecting a new residence, business premises, or other facility to the electricity grid.

Re-examination due to expiration

Each YDE (Licensed Electrician's Declaration) has a specific validity period. Before it expires, a new inspection of the installation and the issuance of a new declaration are required.

Change of owner or user

In certain cases, a valid Electrical Installation Certificate (YDE) may be required upon a change of user, tenant, or ownership status of the installation.

Change of use of the premises

When a residence is converted into a commercial space, or when the activity and electrical loads change substantially.

Modification or expansion of an installation

Following a major electrical renovation, an extension, the installation of a new distribution board, the addition of new high-power loads, or other significant changes.

What happens when problems are detected?

The inspection is not merely a formality. If deficiencies are identified during the on-site assessment or measurements, we provide you with a detailed explanation of the necessary corrective actions.
The work may include:
– replacement of an old or unsuitable distribution board,
– installation or replacement of a residual current device (RCD),
– rectification of grounding issues,
– replacement of worn cables or components,
– separation of overloaded circuits,
– proper circuit protection (fusing/circuit breakers),
– labeling and organization of the distribution board.
Once the necessary work is completed, a re-inspection is conducted; if the installation is deemed safe, the issuance of the Electrical Installation Inspection Report (YDE) proceeds.

Electrical Plans & Issuance of YDE (Certificate of Compliance)

What the service includes

Issuance and Submission of Electrical Installation Certificate

After the successful completion of the inspection and the rectification of any issues, the Electrical Installation Certificate is prepared and submitted along with the required accompanying documents. The current procedure of DEDDIE mandates a digital signature from the authorized installer and electronic submission, together with the relevant
declaration from the owner or user.

Inspection Protocol

We record the results of visual inspections, tests, and measurements in the corresponding protocol.

Electrical Plans

We draft or update the required plans, such as:
- single-line diagram of the electrical panel,
- floor plan of the electrical installation,
- mapping of key circuits and points,
- grounding and protection details.

Electrical measurements

We conduct the required tests and measurements using appropriate instruments to evaluate the safety and proper operation of the installation.

Visual inspection

We inspect the equipment, wiring, panels, and protective devices for signs of wear, deficiencies, or areas requiring repair.

Installation Inspection

We inspect the electrical panel, wiring, protective devices, grounding, and the general condition of the installation.
