If you are an expat in Germany, you probably spend way too much on your gas bills. Energy prices have risen to record levels over the past years and if you do not choose your gas provider deliberately, you end up in the so called 'Grundversorgung', which is the most expensive standard tariff of the local gas company.
The easiest and fastest measure you can take to cut your energy bills is to switch to a cheaper provider (Versorger). Today there are more than 500 gas providers (Gasanbieter) in Germany and gas prices (Gaspreise) vary from region to region due to different network charges. The easiest way to make sure you get the best deal is to conduct a gas price comparison (Gaspreisvergleich).
1-Gasvergleich.de provides you with a very easy to use gas rate comparison calculator (Gasrechner). Your just enter your zip code and get the best results from all the big comparison platforms.
