Replacing an aging or inefficient boiler can represent a major investment for households. However, there are a number of financial aids available from the government and other bodies to help you reduce the cost of this project. In 2025, various grants and tax credits are available to encourage the energy transition and the installation of more efficient equipment. Find out more about the main financial assistance available for replacing your boiler.
Public assistance for boiler replacement
1. MaPrimeRénov’
MaPrimeRénov’ is a financial aid scheme set up by the French government to promote energy-efficient home renovation. In 2025, it remains one of the most accessible forms of assistance for households wishing to replace their boiler. It is awarded on the basis of your income and the type of work carried out. If you replace an old boiler with a more efficient model (condensing boiler, heat pump, biomass boiler, etc.), you can benefit from substantial financial assistance.
2. Zero interest rate eco-loan (Eco-PTZ)
The Eco-PTZ allows you to finance energy renovation work interest-free. This zero-rate loan is available to homeowners who wish to replace their boiler. In 2025, the conditions of the Eco-PTZ remain advantageous, with the possibility of borrowing up to €30,000 to finance work to replace boilers and other energy installations. This assistance can be combined with MaPrimeRénov’ to maximize financing.
3. Reduced-rate VAT
For energy renovation work, the applicable VAT is reduced to 5.5% instead of 20%. This reduction applies to the purchase and installation of a new boiler as part of energy renovation. If you replace an inefficient boiler with a more environmentally-friendly model, you can benefit from this reduced VAT, which considerably reduces the cost of the work.
4. Energy Savings Certificates (CEE)
CEE are financial incentives provided by energy suppliers. When replacing a boiler, you can benefit from CEE bonuses that vary according to your project and the type of equipment installed. These bonuses are often offered by energy distributors, and it’s advisable to check with your supplier to find out if you are eligible.
Local and regional aid
1. Local authority aid
Some regions, départements or communes have their own financial aid schemes to support boiler replacement projects. This may take the form of grants or reduced-rate loans. In 2025, these aids vary according to where you live, and it’s advisable to check with your local council or region to find out if specific aids are available to you.
2. Assistance from energy associations
In some regions, energy associations offer special grants for boiler replacement. These grants are generally designed to encourage residents to adopt more ecological and efficient heating solutions. They can be combined with other schemes such as MaPrimeRénov’.
How can you benefit from this aid?
To qualify for financial assistance in 2025, a number of conditions must be met. It’s important to use an RGE (Reconnu Garant de l’Environnement) certified professional to install your new boiler. This label is often required to qualify for subsidies. What’s more, the work must be carried out as part of an energy-efficiency renovation and involve certified equipment.
Conclusion
Replacing a boiler in 2025 can be largely financed thanks to a range of financial incentives. MaPrimeRénov’, zero-rate eco-loans, reduced VAT and Energy Savings Certificates are just some of the ways in which you can reduce the cost of the work. Don’t forget to ask about local and regional grants too. For further information or a personalized estimate, don’t hesitate to contact our experts.
