When carrying out electrical installations in our home or premises, we often hear the terms “Electrical Plan” and “YDE” (Certificate of Electrical Installation). What exactly do these mean, and why are they important?
What is an electrical plan?
The electrical plan is the “map” of the electrical installation. It shows how the wiring, switches, sockets, and fuses are connected in your space.
This plan shows:
- Where the electrical outlets and switches are located.
- How electrical power is distributed among the various areas (kitchen, living room, bedrooms, etc.).
- Where are the fuses and switchboards that protect the electrical circuit.
- Which lines are grounded for safety.
The plan helps both the electrician and you understand exactly how the electrical system of your home or business premises is structured. It is particularly useful when repairs, additions, or upgrades are required, as it shows the existing setup and how the work can be carried out correctly.
Furthermore, the electrical plan is essential for verifying the safety of the electrical installation and for issuing the YDE (the official certificate), which confirms that everything was carried out in accordance with regulations.
What is YDE?
The YDE (Installer’s Responsible Declaration) is the official certificate signed by the electrician, declaring that the installation was carried out correctly and in accordance with safety regulations. The YDE is always accompanied by the electrical schematic.
Why do you need the electrical plan and the YDE?
Safety: To ensure that your premises’ electrical system is safe.
Legality: Without these, you cannot activate the electricity supply from PPC or another provider.
Quality: They ensure that the installation was carried out by a professional electrician.
Property value: They are essential for sale or rental, as they demonstrate the legality and good condition of the installation.
When is the Electrical Plan/Certificate (YDE) mandatory?
The issuance or re-issuance of the YDE (Electrical Installation Inspection Certificate) is required in the following cases:
- New electricity supply (e.g., newly constructed buildings or new grid connections).
- Power reconnection after an outage.
- Change of use to commercial premises (in accordance with Law 5106/2024).
- Changing the name on the electricity account when the previous Certificate of Electrical Installation (YDE) has expired.
- Increase in power supply capacity (e.g., from single-phase to three-phase).
- Power supply for the construction site.
- Extension or modification of the electrical installation.
- Change of electricity supplier, upon request.
- Validity and Renewals of the YDE Certificate
The validity period of the YDE varies depending on the premises:
Residences: Renewed every 10 years.
Commercial premises and retail stores: Renewed every 5 years.
Special facilities (industrial plants, service stations, hospitals, public assembly venues): Renewed every 2 years.
Furthermore, the Responsible Declaration of the Licensed Electrician (YDE) must absolutely be issued:
In cases of a change of use or a change of owner/tenant for a commercial space.
After modification or extension of the installation.
Upon reconnection following a disconnection, if the certificate has expired.
After damage or an accident (e.g., fire, flood).
Failure to renew the Electrical Installation Inspection Certificate (YDE) within the prescribed timeframes can lead to a power disconnection by DEDDIE and legal penalties. Therefore, it is advisable to schedule an inspection of your installation with a licensed electrician in good time.
Legal Framework and Regulations
The issuance of the electrical schematic and the YDE (Declaration of Electrical Installation) is mandatory under Greek legislation, which aims to ensure the safety of electrical installations and the people who use them. These regulations are based on Law 5106/2024 and other safety standards.
This requirement ensures that your electrical installation complies with the most modern and safe standards.
What to Consider Before Commissioning Electrical Work
Before assigning your project, ensure that the electrician you choose:
- It holds the appropriate license and certifications.
- It provides an official electrical schematic and a Certificate of Compliance (YDE).
- It provides clear and comprehensive information about the project.
- He guarantees the quality of his work.
- He is available for technical support after completion.
FAQ — Frequently Asked Questions
1. How much does it cost to issue the YDE (Certificate of Electrical Installation)?
The cost depends on the size and scope of the electrical installation. Contact us for a no-obligation quote.
2. How long does the issuance take?
The process is usually completed within a few days, depending on the project.
3. What happens if I don’t have a YDE?
PPC does not activate the power supply without a Licensed Electrician’s Certificate (YDE), while any inspections may result in fines.
4. Is a new electrical plan and a Declaration of the Licensed Electrician (YDE) required if I upgrade the lighting or the electrical installation?
If you make minor changes, such as replacing light fixtures or adding a few lighting points, a new plan or YDE (Electrician’s Compliance Certificate) is usually not required. However, when the changes are significant—such as new wiring, replacing the distribution board, or an extensive upgrade—a new electrical plan and YDE certification are required to ensure the installation’s safety and compliance with regulations.
