  • Only the existing boiler system will be replaced by the heat transfer station for district heating. The heat distribution in the building remains the same. By removing the existing boiler plant, you gain additional space.

  • The costs for the connection, the so-called “connection fees”, depend on the scope of the work to be carried out (network, transfer station). These are one-off charges payable at the start of the contract and are subject to VAT at 17%.

  • The heat tariffs are defined in the cost estimate which is submitted to the customer beforehand. They are regularly adjusted to inflation and changes in primary energy prices using an adjustment formula.

    LuxEnergie pursues a transparent pricing policy. The monthly invoice is made up of various items. This allows you to exactly track the amount to be paid:

    • a monthly fee for the use of the network infrastructure and heat production facilities
    • the energy consumption: it is recorded by meters at the heat transfer station
    • the VAT of 8% on the total amount of the invoice

  • By signing a SEPA Direct Debit Mandate, you authorize us to automatically debit your bank account with the invoice amounts until revoked by you. This way you do not have to worry about paying your bills.

    Give us the SEPA mandate by filling out the PDF document and sending it to us by post.

    You can also pay your bills by Digicash.
