Like with other utilities, if your new home has gas, it’ll already be flowing when you move in. If you have a house with central heating, it’s likely heated with gas. Many ovens also are gas. You’ll just need to call Gasag and give them your details and read the gas meter for them. You can also do this online. Then it’s the usual drill of set monthly payments followed by yearly readings. Gasag has a monopoly on gas in Berlin but is actually a private joint venture. It can be reached at www.gasag.de or 0180 142 7242. It also has a customer service centre at Friedrichstrasse 185 in Mitte. If you just cook with gas, expect to pay about €30 a month and double that if you also heat with it.
