On November 2, 2026, Ukraine fully launches its 2026–2027 heating season. On this day, residential buildings in Kyiv, Cherkasy, Chernivtsi, Poltava, Zaporizhzhia, Ivano-Frankivsk, Vinnytsia, and Sloviansk are beginning to be connected to the central heating system. In several cities—Ternopil, Khmelnytskyi, and Lviv—heat supply to apartments began a few days earlier, while in Odesa, the boiler room startup is tentatively scheduled for November 9. The general rule, confirmed by authorities in all listed cities, is that the connection of the housing stock occurs in stages, meaning radiators in different buildings will begin to heat up at different times over the course of several days.
Kyiv: Three Thousand Kilometers of Networks and a Seven-Day Startup Cycle
In the capital, the heating season for social infrastructure facilities started on October 16: upon the requests of administrators, 157 medical institutions, 402 kindergartens, and 85 schools were connected to heat, which is nearly half of the city's social infrastructure. Kyiv Mayor Vitali Klitschko explained that starting the centralized heat supply system, with network lengths of about 3,000 kilometers, technically requires up to seven days. This is precisely why the decision to connect the residential sector was made in advance, considering the forecasted temperature drop. Since November 2, heat supply to apartment buildings has been conducted gradually, and the mayor warned residents that in some houses, radiators might start warming up with a delay of one or two days.
Cherkasy, Chernivtsi, and Poltava: Social Sector First, Housing from Tuesday
In Cherkasy, educational and medical institutions were connected to heating earlier than the housing stock, and heat supply to apartments and enterprises began on November 2. In Chernivtsi, according to Mayor Roman Klichuk, the decision to launch heating in residential buildings and enterprises was made at an extraordinary meeting of the executive committee on October 30, taking into account the forecast of a gradual decrease in average daily temperatures; schools, medical institutions, and other city social infrastructure facilities have been heated since October 20. In the Poltava community, the 2026–2027 heating period officially begins on November 2: according to Poltavaoblenergo, boiler rooms are being launched according to an agreed schedule over 48 hours, so some residents will receive heat on Monday, while others will receive it on Tuesday, November 3.
Zaporizhzhia, Ivano-Frankivsk, and Vinnytsia: Phased Startup and Internal System Maintenance
In Zaporizhzhia, boiler rooms will be turned on in stages from November 2 to November 9, reported Regina Kharchenko, secretary of the city council and acting mayor. After the heat carrier is supplied, management companies, HOAs (condominiums), and cooperatives are obligated to adjust internal building systems, remove air from risers, and flush them. The 1580 contact center will begin accepting complaints about the lack of heating from November 10. In Ivano-Frankivsk, boiler rooms began to be turned on gradually on the night of November 2; Mayor Ruslan Martsinkiv expects that by the end of the day, most of them will be operational. 499 buildings remain on centralized heating in the city. The Vinnytsia municipal enterprise Teploenerhopostachannia is starting to supply heat to residential buildings and social facilities; however, due to power outages, the system startup might be prolonged, and heat in apartments will appear gradually. In Vinnytsia itself, the heating season for residents started on November 1: as of 11:00 AM on November 2, heat was supplied to 487 out of 1,210 residential buildings served by Vinnytsiamiskteploenerho, while 47 kindergartens, 9 healthcare institutions, 31 schools, and 3 educational complexes in the social sector are already receiving heat.
Sloviansk, Lviv, Ternopil, and Khmelnytskyi: Who Started Earlier and Who Is Waiting
In Sloviansk, Donetsk region, the heating season for residents began on November 1. According to Mayor Vadym Lyakh, by 2:00 PM on Sunday, heat was already being supplied to 254 multi-story buildings, while utility workers continued work to ensure the heat reached the apartments directly. In Lviv, according to Mayor Andriy Sadovyi, the season began on October 30; the connection lasts several days, and heat in homes was expected over the weekend. In Ternopil and Khmelnytskyi, heat supply to residential buildings was organized in stages starting as early as October 28. In Odesa, the startup of boiler rooms is tentatively scheduled for November 9, although city authorities declare their readiness to start heat supply earlier if weather conditions worsen.
What to Do If Radiators Do Not Warm Up
Authorities in all listed cities give residents the same recommendation: if heat has not appeared in the house within the first 24 hours after the official start, it is necessary to contact the balance holder—the management company, housing cooperative, or HOA. It is these entities that are responsible for flushing risers, removing air, and adjusting internal building systems. In Kyiv and Poltava, it is additionally reminded that in case of mass failures, one can call city contact centers. As a general rule, set in the startup schedules, full coverage of the housing stock takes from two to seven days depending on network length and weather conditions.
