Customers living in a detached home can buy renewable district heat for exactly the amount of their metered consumption.

Contract issues

You can change the question with arrow keys and open and close the answer with space key.

You need not do anything because the heat contract has been drawn up with the housing company. Households in apartment blocks and terraced houses do not have a district heat contract with Helen as they pay a fixed sum for district heat each month in connection with the management charge or rent to the housing company that has drawn up the district heat contract. With this product, you will secure part of renewable heat production for yourself, and it has no impact on the heat contract signed with the housing company.

You can draw up a separate contract on Renewable District Heat. Your current heat contract will remain unchanged.

When you move to a new address, please tell our customer service so that we can update your contract to suit your new home. If you move out of Helsinki, you are entitled to cancel your contract.
