Order an electricity connection to a detached house
If you are building your own house, you will need an electricity connection from your local electricity network company. Usually, you should order the electricity connection already at the start phase of construction, immediately after you have been granted the building permit. In Helsinki, the electricity connections are provided by Helen Electricity Network Ltd. You can order the construction of the installations on the plot from your own electricity contractor or Helen Electricity Network Ltd’s contractors.
