The ΥΔΕ (Υπεύθυνη Δήλωση Εγκαταστάτη, the installer’s responsible declaration) for a home usually costs 50–150 € on the free market, although there are offers from 30 €. ΔΕΗ (the Public Power Corporation) offers a flat price of 108 € (with VAT) for a connection that is energised. If the installation needs corrections, they are charged separately.

02What affects the price
Condition of the installation
high
Without a residual-current relay or earthing the electrician will not sign. Corrections are paid separately.
Floor area and circuits
medium
More circuits mean more measurements and a bigger diagram.
Single-phase or three-phase
medium
Three-phase usually has a higher price on the free market.
Use of the property
high
Commercial premises cost many times more.
Energised or not
medium
For a property without power (reconnection) the price is higher, e.g. 172.80 € instead of 108 € at ΔΕΗ.
03Regional differences
The ΔΕΗ price is the same across Greece, regardless of area and floor area. That makes it a useful reference point for islands and remote areas, where private contractors often charge for travel too. In big cities private electricians are often cheaper for small apartments.
04Tips before you pay
- Ask whether the price includes the diagram, measurements, filing with ΔΕΔΔΗΕ and VAT.
- If the installation is old, first ask for an estimate for the corrections (relay, earthing, fuse board).
- Check that the electrician has the right licence for the type of installation.
- The ΥΔΕ expires: for homes it is usually renewed every 14 years or when the use/supply changes. It is worth checking before a lease or a sale.
- Keep a copy of the ΥΔΕ and the diagram. You will be asked for them at the next change.
05Frequently asked questions
How much does a ΥΔΕ cost for an apartment?
On the free market usually 50–150 €. One source also mentions 30–80 € for a home. ΔΕΗ offers it at 108 € with VAT, if the property has power.
Is there a state price for the ΥΔΕ?
No. The licensed electrician sets the fee freely. The ΔΕΗ price is a commercial service, not a state fee.
What happens if the installation does not pass?
The electrician must refuse to sign until the corrections are made, which are priced separately (e.g. residual-current relay, earthing, fuse board).
How much does a ΥΔΕ cost for a shop?
Usually from 150 € upwards. ΔΕΗ charges 149 € (energised) or 249 € (not energised) with VAT.
When do I need a new ΥΔΕ?
For a new connection, a reconnection after a cut-off, a change of use, an increase in power and when the previous one expires.
Does the ΥΔΕ cost include the power connection?
No. The connection or reconnection fees of ΔΕΔΔΗΕ are separate.
