2026/27 Heating Season: When Will the Heat Be Turned On in Ukraine?
There is no single date for the start of the heating season in Ukraine. The decision to begin heat supply is made by local authorities, taking into account the temperature, the technical condition of the networks, and the security situation.
With the first cold snaps and frosts, Ukrainians are already wondering when their homes will be heated and whether the infrastructure is ready for the new heating season.
According to current regulations, the heating season must begin no later than when the average daily air temperature over three consecutive days does not exceed +8 °C.
This refers specifically to the average daily temperature, not to a single reading on the thermometer in the morning or at night.
At the same time, reaching the +8 °C threshold over three days does not mean that heating will automatically be turned on simultaneously throughout Ukraine. Weather conditions vary by region, as does the technical condition of heating networks.
Certain social infrastructure facilities—hospitals, daycare centers, and schools—may be connected earlier based on decisions by local communities and upon requests from the heads of the respective institutions.
The mechanism for turning on heating in Ukraine is decentralized.
City, town, or village authorities determine when the heating season begins in their community. After that, heating companies start up their equipment and begin supplying heat to consumers.
However, heat does not necessarily reach all buildings in the city at the same time. Connections are made in stages, and the time it takes for heat to actually reach a specific apartment depends on the operation of the boiler room, the condition of the heating networks, and the building’s internal heating system.
Preparations for the 2026/27 season began well in advance.
According to government data, as of September 7, 79.2% of the housing stock was ready for heat supply. More than 114,000 of the nearly 144,000 planned residential buildings were prepared.
At the same time, damage to energy infrastructure caused by Russian attacks remains an additional risk factor.
According to Naftogaz, the group’s facilities have suffered 287 attacks since the beginning of 2026. Therefore, this heating season, it will be important not only to ensure the technical condition of heating networks but also to ensure that communities can maintain heat supply during potential accidents and power outages.
If the heating season has officially begun in a community but the radiators in an apartment remain cold, consumers should contact their service provider or building manager.
When making the request, it is advisable to note the address, the time the heat was out, and the temperature inside the premises.
For residential units in buildings whose design documentation was approved before October 1, 2005, the standard temperature is +18 °C. For newer residential buildings, the relevant state building codes apply.
If the service is provided improperly or no heat is reaching the building at all, the consumer has the right to request an inspection and the preparation of a complaint report.
A representative of the service provider or building manager must arrive within the timeframe specified in the contract, but no later than one day after the request is made. If the representative fails to arrive or refuses to sign the document, the report may be prepared by the consumer and other residents of the building.
If a violation is confirmed, the consumer has the right to request a recalculation of the service fee.
However, the cause of low indoor temperatures may not be solely related to the heating provider’s operations. It is also influenced by the condition of the building’s internal heating system, windows, insulation, and other building characteristics.
As of September 11, 2026, there is no specific nationwide date for the start of the heating season.
The main factors remain the actual temperature in the fall and the security situation, which directly affects the technical ability to provide heat.
The Ukrainian Hydrometeorological Center forecast an average monthly temperature of 11–18 °C for September, which is close to the climatic norm.
Therefore, a widespread start of the heating season as early as September is not currently expected. October remains the traditional benchmark for the start of the season.
At the same time, heating may be needed earlier in the northern, western, and mountainous regions, while in the southern regions, the season may begin later.
Thus, Ukrainians should rely primarily on decisions by local authorities, actual temperatures, and the readiness of their specific community, rather than on the fixed date of October 15.
In late August 2026, Ukrainian President Volodymyr Zelenskyy enacted a decision by the National Security and Defense Council regarding preparations for the 2026–2027 heating season.
Regions were instructed to strengthen the protection of critical infrastructure, increase backup power by 20%, and build up a fuel reserve of at least two weeks.
All of this should help communities ensure a stable heating season even in the event of new Russian attacks on the energy system.
Kyiv Mayor Vitali Klitschko noted that Kyiv is nearly 90% prepared for the new heating season.
In Zaporizhzhia, two underground electrical substations are scheduled to be commissioned before the start of the new heating season. This was announced on August 19 by Ivan Fedorov, head of the Zaporizhzhia Regional State Administration, who emphasized the importance of preparing the city’s power grid for winter.
