Sign a district heating contract well in advance

The heating contract of a new building is signed once the construction permit has been obtained and the construction schedule has been confirmed, or no later than upon the commencement of the building's foundation work. A district heating contract for an existing property is signed when the building owner or representative announces that they want to connect the building to the district heating network.

For those replacing other forms of heating with district heating, we will prepare a tender calculation based on the information we have received in the invitation to tender.
