By switching to a natural gas plan from Grünwelt Energie, you’ll enjoy multiple benefits: Thanks to our streamlined organization, we offer affordable rates and supply you with 100% sustainable, climate-neutral natural gas. This is good for the environment and easy on your wallet. Of course, we don’t skimp on service—our friendly customer service representatives are here to help with any questions or concerns you may have regarding your energy supply.

Any gas customer with their own meter can switch to us conveniently and securely. To do so, first enter your ZIP code and your consumption into our rate calculator, and you’ll receive a non-binding price quote. Then simply click the “Order” button, and we’ll guide you step by step through the ordering process—via an encrypted connection, of course. At the end, you’ll receive an order confirmation that you can print out for your records. Just a few days later, you’ll receive your contract confirmation from us. In the meantime, we’ll take care of all the formalities. If necessary, we’ll cancel your old gas contract and switch you over to our affordable rates exactly on the delivery date, without any interruption to your gas supply.

If you rent an apartment with its own gas heating system, you can easily switch to us. The same applies if you rent a house with its own gas meter. If you live in an apartment building without your own meter, you should discuss switching to us with your landlord or property management company, as the meter may be shared among several residents.

To switch gas providers, you will need your gas meter number, your gas consumption for the past year, and your customer number from your current provider. You can usually find all this information on your most recent gas bill. We also need your billing address and, if necessary, a SEPA mandate to process your order. All data is transmitted via an encrypted connection and handled in accordance with the Federal Data Protection Act.

You generally do not need to cancel your existing gas contract yourself, as you can grant us power of attorney to do so as part of your order. We will then cancel your old gas contract on your behalf in time for the start of service and handle all the necessary paperwork. The only exception: If you wish to switch to us due to a price adjustment or another short-notice termination option, you should terminate your contract yourself due to the tight timeline. In this case, please let us know the end date of your contract when placing your order.

No, no additional contracts are required; by placing your order with us, you have already taken care of everything necessary.

No, of course there are no fees for switching to us.

If you are already a Grünwelt Energie customer and would like to place another order, please give us a call—our friendly service experts will be happy to work with you to explore the options available for your contract. You can reach our customer service team using the contact information provided.

There are legally mandated deadlines for switching gas suppliers that all providers must adhere to. If your current contract does not include long notice periods, we need about four weeks from the time you place your order until service begins. Shortly after you place your order, we will send you a contract confirmation with an estimated start date for service. We will then cancel your old gas supply contract and register your supply point with the relevant network operator. Both your previous supplier and the network operator must confirm these steps to us. Once we have the green light from both, we will immediately inform you of the good news with a supply confirmation.

We do our very best to meet your requested delivery date. However, in order to switch providers, we also need to coordinate with your current provider and the local network operator. If any issues arise, we will of course notify you immediately and work to find a solution right away so that we can get you connected as soon as possible.

Yes, even if your old contract still has some time left on it, you’re welcome to place an order with us in advance. The remaining term of your old contract can be up to 12 months.

Yes, if you are exercising your right to early termination, you can let us know when placing your order. We will then schedule your delivery accordingly.

Your utility provider will contact you to obtain your meter readings at the start and end of your gas service. We recommend that you always provide your meter readings to your utility provider and make a note of them for your records.

No, due to legal regulations, it is impossible for your gas supply to be interrupted when you switch providers. The local backup provider ensures a continuous supply of gas at all times—even if a problem should arise.

We first calculate your estimated bill for the coming year and then divide it into equal monthly installments so that the difference at the end of the billing period is as small as possible. You will find the exact amount and payment dates in your order confirmation. You can pay your installments via SEPA direct debit or bank transfer.

The base rate is a fixed annual fee included in your contract and is billed on a monthly basis. The usage rate is the variable charge per kilowatt-hour of gas consumed.

The estimated bill amount for the coming year is divided into monthly installments so that the difference at the end of the billing year is as small as possible. To calculate this, your consumption is multiplied by the rate per kilowatt-hour, and the annual base fee is added. The result, divided by the number of months, gives the monthly installment amount. Any new customer bonus that may have been agreed upon is not included in the monthly installments, as this will be paid out to you on the dates specified in the contract.

After one year of service, we will first ask you to provide us with your meter reading. We will then prepare your consumption bill for the past year and send it to you.

For some plans, we offer a new customer bonus. This bonus may be provided as a percentage credit toward the total cost of gas service during the first year of service or as a bank transfer a certain number of days after service begins. The specific terms and the amount of the bonus depend on your plan and are clearly outlined in your order form and contract confirmation.

If we have agreed to a limited price guarantee, we may not change prices during this period. Exceptions to this include changes to the fees payable to the market area operator (e.g., SLP balancing charge, conversion charge), the concession fee, and the gas and energy taxes. Excluded are also price changes to the extent that new taxes, levies, or other government-imposed charges or reliefs affecting the procurement, production, grid use (transmission and distribution), or consumption of gas take effect in the future. Section 6 of our General Terms and Conditions applies to price changes.

Please let us know about your move at least two weeks in advance, for example via our contact form. We would be happy to continue providing our services at your new address at our competitive rates. Please contact us by phone or email, and we will be happy to provide you with an attractive quote.

If you are the first occupant to move into a new property and would like to be supplied with gas at Grünwelt’s competitive rates, you can still sign up retroactively up to 6 weeks after moving in. Otherwise, the local utility provider will initially supply gas to your new home on a temporary basis. Please let us know your desired start date for service when placing your order.

When you move into an apartment, we will need information from you, including your planned move-in date and the meter number for that apartment. You can usually obtain this information by contacting your future landlord.

A kilowatt-hour is a unit of energy. It refers to the amount of energy released or absorbed at a power of 1,000 watts per hour.

No, you do not need to make any changes to your gas connection. You also do not need to replace the meter.

No, due to legal regulations, it is impossible for your gas supply to be interrupted when you switch providers. The local backup provider ensures a continuous supply of gas at all times—even if a problem should arise.

At the end of each billing year, we will ask you to take a reading of your meter and submit it online. In addition, the local utility may take readings.

In the event of disruptions to the gas supply, your local network operator remains your point of contact, as before. The operator is required to continue resolving such disruptions. We pay a usage fee for the operation and maintenance of meters and the gas network, which is already included in your bill.

All personal data we receive from you in connection with the gas supply contract will be handled in strict compliance with applicable data protection laws. This means that we collect, process, and use your data solely for the purpose of fulfilling the contract and providing support and advice regarding your gas supply from us. Grünwelt will not sell or otherwise market your data to third parties.

Our affordable gas continues to flow through the gas network to your home connection, just as before. We use the existing pipes and lines for this purpose, for which we pay a usage fee to the gas network operator. These fees are, of course, already included in your gas bill.

If your gas consumption is only available in cubic meters (m³), you will need to convert it to kilowatt-hours (kWh). The volume in m³ is multiplied by the gas calorific value and the condition factor. These two values are determined by the utility company for the delivery location. For an estimate, the volume in cubic meters can be multiplied by 10.
