If you are connected to district heating (fjernvarme) and water (vandværk), you should keep an eye on the yearly general assembly (generalforsamling). As a user, you can vote and candidate for the leadership (bestyrelsen). Also, at the general assembly, you can discuss the price and what happens with the common resources, among other things.
You can check the website of your district heating/water company (check your latest bill if you don’t know the name) – scroll down the latest news until you find one related to the general assembly – or you can just call to ask when the next one is. If you’re wondering if it’s important to have a say over how your district heating is run, just take a look at the current situation. 200,000 houses connected to district heating will experience massive increases in price, while 1.6 million houses also connected will not. Why? Because some district heating companies have chosen to run only on gas or electricity.
