Gas, electricity and water
No water supply company included in the utility costs of your rental contract? Ask the local town council to direct you to the appropriate company.

As a matter of course, this concerns your house or apartment’s distribution system. For electricity or gas, the German energy market was liberalized at the end of the 1990s. You can choose between many providers but be sure to inquire about their offers and compare their services with other companies first. On websites such as www.vervox.de or www.biallo.de you can compare the offers of the providers.
