Sofia Central Heating to Switch On Gradually from 29 October

Toplofikatsiya Sofia has announced that it will begin the phased switch-on of central heating across the capital from Thursday, 29 October 2026. Schools and kindergartens will be connected first, followed by residential and administrative buildings.

According to weather forecasts for the next seven days, temperatures are expected to drop below seasonal averages, prompting the start of the heating season.

Residents who wish to delay the heating in their building must submit an official application to a customer service centre, accompanied by a protocol from the building's general assembly decision. The company also reminds customers to complete any repairs to internal installations and ensure systems are filled if they were drained. Heating will not be switched on in buildings where the internal installation is not filled.

To help the process run smoothly, customers are advised to fully open the thermostatic valves on their radiators to avoid the need for extra bleeding. They should also check the displays of electronic heat cost allocators fitted on radiators; if a display is blank, contact the building's heat accountant.

Further information about the start of the heating season is available on 0700 11 111 or through the company's digital channels.
