WHAT TO DO
What is it and when to do it?
A gas contract is only needed if your apartment has gas central heating or a gas hob and those costs are not included in the rent (Kaltmiete). As with electricity: the Grundversorger connects you automatically on move-in day, so your first step is photographing the gas meter reading the moment you get the keys.
Where and how much does it cost?
Switching provider is free: signing the contract takes 5–10 minutes online, the switch itself 1–2 weeks. Compare on Verivox↗.de or Check24↗.de. The gas meter is usually in the basement, boiler room, or a utility cupboard in the hallway — ask your landlord. You’ll need the meter number (Zählernummer) to sign up.
Saw 'Warmmiete' in the contract and still took out a gas contract with the Grundversorger. Paid double for three months before I noticed. Always read the tenancy agreement carefully before signing any energy contract.
👩🏼💼
Lea recommends:
Turned on the gas boiler without checking it — a week later found out the ventilation wasn't working. That's life-threatening. At move-in, always request the boiler's maintenance record and don't operate any gas appliance until the landlord confirms it's safe.
FREQUENTLY ASKED QUESTIONS
How do I know if I need my own gas contract?▾
Check your tenancy agreement: look for the words Warmmiete or Heizkosten. If heating and hot water are included in the rent, you don't need a separate gas contract — the landlord handles billing. If the contract states Kaltmiete without a heating cost component, you need your own gas contract.
What is the Grundversorger for gas?▾
Under § 36 EnWG every area must have a default gas supplier that is obliged to serve any household. As with electricity, they connect you automatically when you move in — at the highest tariff. It's worth comparing alternatives on Verivox or Check24.
Is it dangerous to turn on gas appliances yourself when moving in?▾
Yes. Do not switch on a gas boiler, water heater or hob without a prior safety check. Ask your landlord for the Wartungsprotokoll (maintenance record) and confirm the ventilation is working properly. If in doubt, call a certified engineer — this is the landlord's responsibility.
