A network nearby—or an area marked as suitable or planned—does not guarantee a connection. Confirm eligibility, timing, capacity, costs, and required building work before making a heating decision.
How to check district-heating availability
- Search your exact address. Use the official heat-network portal recommended by your municipality or utility. The lookup may ask for a full address or just a postcode. For example, France’s Montpellier directs residents to the France Chaleur Urbaine address search; Denmark’s consumer guidance points to a postcode search for availability and supplier details; and Wien Energie asks for the home address in its checker. Montpellier’s recommended address search, Denmark’s district-heating guidance, and Wien Energie’s availability checker illustrate the local approach.
- Interpret the status, not just the map. Check whether the result means the building is already connected, a connection is currently possible, an expansion is underway or planned, or the area is merely considered suitable. Hamburg’s map indicates where a network might make economic sense; it does not promise construction or a connection for a particular building. Wien Energie’s checker distinguishes several connection and expansion statuses, and warns that some address information may not yet be current. Hamburg’s heat-network maps and guidance explain the map’s limits.
- Contact the operator identified by the lookup. Ask whether it serves your exact building, has capacity, and is accepting connections. If an extension is planned, ask whether it has a firm schedule. In Hamburg, the city says only heat-network operators can make binding connection commitments; a map is not one. Hamburg’s connection guidance explains how to proceed.
- Check the building’s existing heating system. A main in the street does not establish that your property is connected or ready to connect. Ask the owner or building manager what system is installed and recorded. Denmark’s guidance points to the Building and Housing Register for the building’s heating installation. Wien Energie advises residents without an available functioning connection to consult the property manager or owner about a new building connection or installation.
- Get the practical terms in writing. Ask about the connection charge, heat exchanger and other equipment, technical requirements, work needed inside the building, capacity constraints, and the likely connection date. Denmark notes that fees typically apply when an unconnected property chooses to connect, and that a heat exchanger may also be an expense. Hamburg cautions that some connections can take several years and may require substantial modernization, such as installing central heating.
What the map can—and cannot—tell you
Availability tools are useful for identifying a possible network and the operator to contact, but their labels are not interchangeable. Existing coverage, a planned expansion, and an area considered suitable for future development describe different levels of certainty. Even an existing network near your home does not confirm that the operator can connect your building. Treat the lookup as the start of an inquiry and get a building-specific answer from the operator.

Check the date and any caveats displayed by the tool. Address data can lag behind current network conditions, and an expansion plan may not have a firm construction or connection date. If a result is unclear or appears out of date, ask the operator to verify it.

Questions to ask the operator and property manager
- Is this exact building within your service area, and can it connect now?
- Is capacity available, and are you currently accepting connection requests?
- If connection depends on an extension, is it approved and scheduled? What is the earliest credible date?
- What are the connection charge and equipment costs, and what ongoing charges should the building expect?
- What work is required on the building’s side, including any central heating or heat-exchanger installation?
- Who must approve the work—the owner, property manager, building association, or another decision-maker?
- Can you provide the eligibility, costs, technical conditions, and timing in writing?
Compare feasible heating options before committing
District heating being available does not automatically make it the best choice. Compare it with alternatives that are technically feasible for the property, such as a heat pump. Consider the full lifecycle cost, including connection and building work; the earliest credible installation date and confidence in the schedule; space and technical fit; operating and maintenance responsibilities; and who has authority to make the building’s decision. Hamburg’s guidance recommends considering costs alongside practical factors such as indoor or outdoor space and operating and maintenance effort. If replacement is urgent or the decision is complex, seek advice specific to the property.

Why the right lookup depends on where you live
There is no single universal address checker or connection rule. Start with your local authority or utility’s recommended tool, then confirm the result with the operator serving your area. Official examples include the France Chaleur Urbaine lookup for Montpellier residents, Denmark’s postcode-based guidance, Wien Energie’s address checker, and Hamburg’s municipal maps. Their labels and processes are local; for example, Danish rules about heating supply should not be assumed to apply elsewhere.
