Charging an electric car in an apartment block

Can you charge in an underground car park at all?

Yes, charging in an underground car park is permitted, but for fire-safety reasons it often requires a fire-safety assessment. An enclosed car park is a space with stricter requirements, so the installation is not something to do “on your own”.

UDT acceptance (by Poland’s Office of Technical Inspection) depends on how the charger is used. If you use it individually — as a private wallbox for a single user — UDT acceptance is usually not required. However, if it is an internal charging station serving many residents, it is subject to technical inspection and requires UDT acceptance.

Who has to agree

Parking spaces in an apartment block usually belong to the common property or are assigned to units, so installing a charger requires the consent of the housing community or housing co-op. Most often, a resolution setting out the rules for installation and billing is needed.

So the association doesn’t pay extra

The key is to assign consumption to a specific resident — so that everyone pays for their own sessions and the association doesn’t pay for a neighbour’s electricity, with no commission on energy sales. Metering can be done in several ways, depending on the installation and technical conditions:

• A MID-certified submeter on the charger circuit — consumption is read and billed by the Domena Power system, per user and with authorisation in the app.
• A charger with a built-in MID meter — metering is in the device itself, and billing is handled by the Domena Power system.
• Your own DSO meter (a separate contract with the distribution system operator) — where technical conditions allow; the resident then pays for energy directly to the operator, outside the common-area billing.

The scope of requirements (including fire safety) depends on the specific building. Confirm it before installation.
