Changing your gas boiler in 2025: what government aid is available?

In 2025, many French households face the necessity of upgrading their heating system, mainly due to new environmental and economic requirements. Replacing a gas boiler can be expensive, but the government provides significant assistance to ease the financial burden of this transition. This article examines the support mechanisms available, highlighting the actions established under the government of Prime Minister Élisabeth Borne, and explores solutions to optimize access to these subsidies.

Government Assistance for Replacing Gas Boilers

As part of the current energy policy, several aids have been established to facilitate the energy transition. In particular, the boiler conversion bonus. Since March 1, 2023, it has been increased to a minimum amount of 5,000 euros.
