Connecting to the District Heating Network in Poland

Legal basis

The connection of buildings to district heating networks in Poland is governed primarily by the Energy Law Act (Ustawa Prawo energetyczne, Dz.U. 1997 nr 54 poz. 348, with subsequent amendments) and regulations issued by the Minister of Climate and Environment. The Energy Regulatory Office (URE) oversees compliance and handles tariff approvals. Each distribution company operates under a licence granted by URE and must publish its connection conditions and tariff schedule.

Step 1 — Determining network availability

The first step is establishing whether the district heating network passes within a technically and economically justifiable distance of the building. In Poland, the Energy Law obliges operators to connect buildings located within the coverage area of their network, provided the connection is technically feasible and cost-effective. The operator assesses this based on the building's heat load, distance from the nearest distribution pipe, and available network capacity.

Prospective applicants can contact the local heat operator directly or check the publicly available network coverage maps that major operators publish on their websites. For example, Veolia Energia Warszawa publishes an interactive map showing the extent of its Warsaw primary and secondary network.

Step 2 — Submitting the connection application

The building owner or authorised representative submits a formal connection application (wniosek o wydanie warunków przyłączenia) to the heat operator. The application typically requires:

• Proof of legal title to the property (land register extract or notarial document)
• Estimated thermal power demand in kW, broken down by space heating and domestic hot water preparation
• Address and cadastral number of the building site
• Building permit number, if the connection is for new construction
• Preliminary architectural plan or building energy calculation (if available)

Each operator has its own application form; most now accept electronic submissions. Processing time for a connection conditions decision (warunki techniczne przyłączenia) is set by regulation at up to 30 days from a complete application.

Step 3 — Receiving technical conditions

If the operator approves the application, it issues a technical conditions document specifying:

• The point of connection on the primary or secondary network
• Maximum contracted thermal power (in kW or MW)
• Required supply and return temperatures at the delivery point
• Metering location and type
• Substation configuration requirements (indirect connection with heat exchanger is standard for new connections)
• Validity period of the conditions (typically 2–3 years)

Step 4 — Connection agreement and cost

Before construction begins, a connection agreement (umowa o przyłączenie) is signed. Connection fees are set according to the tariff approved by URE and are calculated based on contracted power, distance of the connection pipe, and complexity of the work. The fee structure is published in the operator's tariff schedule and cannot exceed amounts set by regulation.

For existing buildings converting from individual gas or coal boilers, connection costs are sometimes offset by urban heat transition subsidies available at the municipal level. In Warsaw and Kraków, dedicated programmes have provided partial co-financing for connection fees in buildings located in air quality protection zones.

Step 5 — Substation installation and commissioning

The heat substation must be designed and installed by a licensed thermal installation engineer. The operator inspects the completed substation, verifies conformity with the technical conditions, and activates the connection. Final commissioning includes pressure testing, calibration of the heat meter, and registration of the meter reading as the starting point for billing.

Step 6 — Supply agreement and tariff

Following commissioning, a heat supply agreement (umowa sprzedaży ciepła) is signed. The tariff applicable to the consumer is the one approved by URE for the relevant operator and consumer group. Tariffs are revised periodically — major operators typically submit tariff revision applications to URE once or twice per year. Current approved tariffs are published on the URE website.
