How the gas switch actually works
Three steps, and that is the whole list.
- Enter your postal code and yearly gas use in kWh. Your last gas bill shows the figure under Jahresverbrauch.
- Pick a tariff. The widget shows the total yearly price, the price guarantee period, and the cancellation period for each one.
- Sign up with your IBAN, your meter number (Zaehlernummer), and your current customer number.
You do not call anyone. You do not post a letter. You do not email your current provider to break up. The new provider takes care of the handover, including cancellation, on your behalf.
How long until the switch is done?
Four to six weeks for most contracts. The Bundesnetzagentur (Germany's Federal Network Agency) sets the rules around switching, and providers are legally bound to finish the process inside that window. If your current contract has a longer cancellation period (some run three months), the new tariff simply starts the day after the old one ends.
You get a confirmation email with the activation date. Mark the calendar. That is the day the savings start counting.
Will my gas get shut off during the switch?
No. Section 36 of the German Energy Industry Act, Section 36 EnWG, makes your local grid operator responsible for keeping you supplied no matter what. This duty is called Grundversorgungspflicht, or universal supply duty. If a new provider goes bankrupt mid-switch, which does happen now and then, your local default supplier picks you up automatically.
The worst case is not "no gas." The worst case is "gas at the default price for a few extra weeks." That is it.
When can I cancel my current gas contract?
The answer depends on what you signed.
- Grundversorgung (default tariff): You can cancel any time with two weeks' notice. No reason needed.
- Regular fixed-term contract: You are locked in for the agreed period (usually 12 or 24 months). When the provider raises the price, Section 41 Abs. 5 EnWG gives you a Sonderkundigungsrecht: one month to cancel from the day the new price takes effect.
Read your last bill closely. If a price increase is announced for next month, your window is open right now.
Comparing vs switching: what is the difference?
Comparing is the research phase. You look at tariffs side by side, you weigh price guarantees, you read the fine print. If that is what you came for, compare gas providers in Germany is the better stop. It goes deep on the comparison criteria and the customer rights you have once you sign.
Switching is the action phase. You already know you are paying too much, you have a rough sense of the market, and you want to be done with it before dinner. That is this page.
Both paths use the same widget. The difference is how long you sit with the comparison before you click.
A few quick wins while you are here
Most households who switch gas also realize they are overpaying somewhere else. Each of these takes about ten minutes:
- Compare electricity providers in Germany. Usually a bigger saving than gas, in our experience.
- Compare car insurance in Germany. Many newcomers overpay because they do not know about the Schadenfreiheitsklasse transfer from their home country.
- Free credit card in Germany. For newcomers without Schufa history, there are cards that issue without a credit check.
- Small loan in Germany, fast. If you want to fold an expensive Dispo (overdraft) into something cheaper.
Frequently Asked Questions
Can foreigners switch gas providers in Germany?
Yes. You need a German address, a German bank account (IBAN), and a working meter number. You do not need a Schufa score, you do not need to be German, and you do not need to speak fluent German to use the widget. The provider will write to you in German by default, but most of the larger ones handle English by email if you ask politely.
How much money will I actually save with an instant gas switch?
Finanztip estimates around 340 EUR per year on average when households move off Grundversorgung (Finanztip, March 2026). The realistic range is wider. A one-person apartment using 8,000 kWh saves about 310 to 530 EUR per year. A family using 18,000 kWh saves 520 to 910 EUR. The larger your use, the larger the gap between the default rate and a new-customer rate.
What about the CO2 price on gas in 2026?
The German national carbon price applies to natural gas in 2026 and adds roughly 1.4 ct/kWh to your bill. For a household using 20,000 kWh, that is about 280 EUR a year extra, baked into the price every provider charges. Switching does not avoid the CO2 surcharge, but a lower base rate softens the impact.
Can a gas provider reject my application?
It happens, but it is rare. The usual reasons: you have switched providers more than three times in two years and the new provider flags you as a "bonus chaser," the address has unpaid bills tied to your name, or the meter number on the form does not match the supply point. The comparison widget will simply suggest the next-best provider with similar pricing.
Is biogas worth the small extra cost?
Biogas is gas produced from biomass, like food waste, agricultural residues, or wastewater. Tariffs run from 10% to 100% biogas content. A 100% biogas tariff usually costs only a little more than a standard one. Be careful with tariffs labelled klimaneutral that are not actual biogas. Those offset CO2 with certificates rather than supplying biomass-sourced gas.
Do I have to read my meter on switch day?
You do, but only once. Your new provider asks for the meter reading (Zaehlerstand) at the handover date. That number divides your old bill from your new one. If you forget, both providers estimate, and at least one of those estimates always lands high.
Bottom line
An instant gas switch in Germany is the rare bureaucratic task that is actually easier than it sounds. The form takes 5 minutes, the handover takes 4 to 6 weeks, your supply is protected by Section 36 EnWG, and Finanztip puts the average household saving at around 340 EUR per year for 2026.
