Comparison Center

German households spend thousands of euros every year on electricity, gas, internet, and mobile phone contracts — often without realizing they are overpaying. S4TN provides free, independent comparison tools powered by Check24 and Tarifcheck that let you compare hundreds of providers in seconds. Simply enter your postcode and current usage, and our tools instantly show you the cheapest tariffs available in your area, including exclusive online discounts and bonus deals you will not find elsewhere.

Our car insurance comparison tool from Tarifcheck makes it equally easy to find affordable Kfz-Versicherung. Compare liability, comprehensive, and partial coverage options from Germany's leading insurers — all in one place. Switching providers is simple and typically takes less than 10 minutes. On average, users who switch through our comparison tools save between 200 and 500 euros per year on their household bills.
