District heating (távfűtés) in Budapest is supplied by FŐTÁV and covers a large share of the city’s apartment stock, particularly in panel buildings and inner-district blocks. It is billed centrally, requires no individual boiler maintenance, and typically costs between 15,000–30,000 HUF per month in winter for a standard 50–70 m² flat, though costs vary by building insulation and metering setup.
What district heating actually is
District heating is a centralised system in which hot water is produced at a large plant and piped through insulated underground networks to residential and commercial buildings. Inside the building, a heat exchanger (substation) transfers that heat to the internal radiator circuit. Individual apartments do not have their own boiler or gas connection for space heating — the heat arrives ready-made.
In Budapest, the dominant supplier is FŐTÁV Zrt. (Fővárosi Távhőszolgáltató Zrt.), a company majority-owned by the City of Budapest. FŐTÁV operates one of the largest district heating networks in Central Europe, with hundreds of kilometres of pipeline running beneath the city. The heat itself comes from a mix of gas-fired combined heat-and-power plants and, increasingly, waste-heat recovery sources.
For apartment buyers, the key practical point is that district heating is not optional at the apartment level. If the building is connected, you use it. You cannot legally disconnect a single flat from the building’s shared system and install an independent gas boiler instead — at least not without the unanimous consent of the homeowners’ association (társasház) and a technically complex retrofit, which is rarely approved.
Which Budapest districts and buildings are connected
District heating is most prevalent in the large panel-block estates built between the 1960s and 1980s. The biggest concentrations are in Districts X (Kőbánya), XI (Újbuda — particularly Kelenföld and Gazdagrét), XIII (Angyalföld and Újlipótváros), XIV (Zugló), and the outer sections of Districts IV, XV, XVI, XVII, and XIX. These are the areas where socialist-era prefabricated housing was built at scale, and virtually all of those buildings are on the FŐTÁV network.
Inner-city districts are more mixed. In Districts V, VI, VII, and VIII — the historic Belváros, Terézváros, Erzsébetváros, and Józsefváros — you will find both district-heated buildings and buildings with individual gas convectors or central gas boilers. Many of the ornate pre-war apartment buildings in District VI along Andrássy út or in District XIII near Pozsonyi út were retrofitted with district heating during the communist era and remain on the network today.
The simplest way to confirm whether a specific building is connected is to ask the seller for the most recent közös költség (common charge) breakdown, which will list távfűtés as a line item, or to contact FŐTÁV directly with the building’s address. FŐTÁV publishes a service-area map on its website. If you are browsing Budapest property listings, the heating type is usually noted in the property description — but always verify with the building’s administrator (közös képviselő).
How billing works: flat-rate versus heat meters
This is where buyers often get confused, and it matters financially. Budapest buildings on the district heating network use one of two billing models.
Flat-rate allocation (arányos elosztás): The building receives one collective bill from FŐTÁV. That bill is then divided among apartments proportionally — usually by floor area (m²), sometimes with a correction factor for floor level or exposure. You pay a fixed monthly amount regardless of how warm you keep your flat. This model is common in older panel buildings that have not been retrofitted with individual meters.
Heat-cost allocators or individual meters (hőmennyiségmérő / költségmegosztó): A growing number of buildings, particularly those that have undergone energy renovation (felújítás), have installed individual heat meters or heat-cost allocators on each radiator. In this case, your bill reflects your actual consumption. You still pay a standing charge (alapdíj) for your share of the building’s fixed network costs, but the variable portion tracks your usage. This model gives you meaningful control over your bill.
When evaluating an apartment, ask explicitly which model the building uses. A flat-rate building in a poorly insulated panel block can produce surprisingly high annual costs because you are subsidising neighbours who overheat their flats. A metered building with good insulation is usually more predictable and fairer.
District heating versus gas convectors: a practical comparison
Many buyers — especially those coming from Western Europe or North America where individual boilers are the norm — ask whether district heating is preferable to a building with gas convectors (gázkonvektor) or a central gas boiler (gázkazán). There is no universal answer, but the table below captures the main differences.
For a buy-to-let investor, district heating has a practical advantage: there is no boiler to break down between tenants, no annual gas safety certificate to arrange, and no emergency call-out at midnight in January. For an owner-occupier who wants precise temperature control and the ability to heat the flat in September before the official season starts, a gas convector building may suit better.
District heating covers hot water as well as space heating in many Budapest buildings — meaning a single monthly line item replaces what would otherwise be two separate utility contracts.
What to check before signing a purchase contract
The heating system should be part of your due diligence, not an afterthought. Here is what to verify before exchange of contracts.
- Confirm the supplier and connection status. Ask for the FŐTÁV contract number or the building’s service agreement. If the building has arrears with FŐTÁV, that debt can affect the entire building’s service.
- Check for outstanding common charges (közös költség hátralék). Unpaid heating bills from a previous owner can, in some circumstances, become a lien on the property. A Hungarian property lawyer will check this in the land registry (ingatlan-nyilvántartás).
- Review the building’s energy performance certificate (energetikai tanúsítvány). Since 2012, sellers are legally required to provide this. A panel building with a DD or EE energy rating will cost more to heat than a renovated block with a CC or BB rating.
- Ask about planned renovations. If the building is scheduled for external insulation (hőszigetelés) or window replacement under a government or EU-funded programme, your future heating costs could drop significantly — but the renovation levy will temporarily increase your common charges.
- Understand the metering setup. As noted above, flat-rate versus individual meters changes your financial exposure considerably.
Working with a local agency that knows how to read these documents matters. Our safe property purchase legal service includes a full review of the building’s financial standing and utility contracts before you commit.
Renovation and system changes: what is and is not allowed
A common question from buyers who want to renovate is whether they can replace the old cast-iron radiators, add thermostatic valves, or switch to underfloor heating. The short answer: radiator replacement and thermostatic valve installation are generally permitted and are often encouraged, since they improve efficiency. Underfloor heating connected to the district system is technically possible but requires the building’s substation to be compatible with the lower flow temperatures that underfloor systems need — this is worth checking with a qualified heating engineer before budgeting for it.
What is not straightforward is opting out of the district system entirely. Hungarian law (specifically the Távhőszolgáltatásról szóló 2005. évi XVIII. törvény — the District Heating Act) governs disconnection. An individual apartment cannot unilaterally disconnect; the entire building must agree, and the technical and administrative process is lengthy. In practice, full disconnections are rare. Partial workarounds — such as adding a small electric infrared panel for a home office — are common and unproblematic.

Running costs and what to budget for
Precise figures depend on the building, the metering model, the apartment’s floor area and orientation, and the annual FŐTÁV tariff, which is regulated and published. As a working guide for buyers:
- A 45–55 m² flat in a non-renovated panel building in District XIII or XIV on flat-rate billing: expect roughly 20,000–35,000 HUF per month averaged across the heating season (October to April), with hot water charges on top if bundled.
- A 60–80 m² flat in a renovated panel building with individual meters in District XI (Kelenföld): typically 15,000–25,000 HUF per month in winter, lower in shoulder months.
- A 40–50 m² inner-city flat in a pre-war building in District VI or VII that was retrofitted with district heating: costs vary widely depending on insulation quality, but 18,000–28,000 HUF per month in winter is a reasonable range.
These figures are illustrative ranges based on market knowledge as of 2025–2026 and should be verified against actual bills for any specific property. FŐTÁV publishes its current tariffs on its website, and the building administrator can provide the per-m² rate the building is currently paying.
For investors focused on net rental yield, heating costs matter because in Budapest it is common for landlords to include heating in the rent (rezsi benne) for short-term lets, and to pass it through separately for long-term tenants. Either way, understanding the building’s heating bill is part of calculating your real return. You can find more on this in our investment thesis for Budapest property.

Frequently asked questions
- Can I turn off district heating in my Budapest apartment if I get too warm?
- You can turn radiators off or down using the valves on each unit, but you cannot disconnect from the system. In flat-rate buildings, you will still pay the same monthly charge regardless of how much heat you use. In metered buildings, turning radiators off will reduce your variable charge, but you still pay the standing fee (alapdíj) for your share of the building’s fixed network costs.
- Is district heating cheaper than gas convectors in Budapest?
- It depends on the building’s insulation and metering setup. In a well-insulated, metered building, district heating is generally competitive with or cheaper than individual gas. In an uninsulated flat-rate panel block, costs can be higher than expected because you are sharing the bill with less efficient neighbours. Always compare actual bills, not assumptions.
- Does FŐTÁV supply hot water as well as space heating?
- In many Budapest buildings, yes. The district system delivers both space heating and domestic hot water through the same network. The hot water charge (melegvíz) appears as a separate line in the building’s cost breakdown. In some buildings, hot water is produced locally by a separate gas boiler even if space heating comes from FŐTÁV — check the building’s setup specifically.
- When does the district heating season start and end in Budapest?
- FŐTÁV typically starts the heating season when the outdoor temperature falls below 10°C for several consecutive days, usually in mid-to-late October. The season ends in April, again based on outdoor temperatures. The exact dates vary each year and are announced by FŐTÁV. Outside the season, district-supplied space heating is not available, though hot water supply continues year-round.
- Will a district-heated apartment affect my ability to get a Hungarian mortgage?
- No. Hungarian banks do not discriminate between heating types when assessing mortgage eligibility. The energy performance certificate (energetikai tanúsítvány) is relevant to valuation, and a lower energy rating may affect the bank’s assessed value, but the heating type itself is not a disqualifying factor. Consult a Hungarian mortgage broker for specifics on your situation.
- What happens if the building has unpaid FŐTÁV debts?
- Arrears to FŐTÁV are a building-level liability. In serious cases, FŐTÁV can suspend service to the entire building. Before purchasing, your lawyer should check for any outstanding utility debts in the building’s financial records and the land registry. This is a standard part of due diligence for Budapest apartment purchases and should not be skipped.
- Can I install air conditioning as a supplement to district heating?
- Yes, and this is increasingly common in Budapest apartments. A split-unit air conditioner provides cooling in summer and can serve as supplemental heating in the shoulder months (September, May) when district heating is off. Installation requires building association approval for the external unit placement, but it is routinely granted in most Budapest társasház buildings.
