5 min read
In a context where the issue of energy efficiency and ecological transition is more relevant than ever, the reduction of VAT to 5.5% for heating work represents a valuable opportunity. Optimizing the energy performance of one's home while benefiting from tax advantages is now within reach. In this article, we will explore in depth the criteria and application procedures of this scheme, as well as the financial implications related to the work. Get ready to discover everything you need to know to fully take advantage of this incentive measure.
Understanding the VAT applied to heating work
Taxation on renovation and energy improvement work is a major issue for property owners. In 2025, building work, whether carried out in a new construction or in an existing home, is subject to different VAT rates: 5.5%, 10%, or 20%. It is essential to know these rates, as they directly impact the total cost of the work. The reduced-rate VAT, if correctly applied, can turn an energy project into a financially viable endeavor for individuals.
What types of work can benefit from the 5.5% VAT?
The reduced VAT at 5.5% is specifically intended for renovation work aimed at improving the energy performance of a home. This includes, but is not limited to:
thermal insulation (of attics, walls, or windows),
replacement of boilers with more efficient equipment,
external insulation.
These works must meet energy performance criteria set by law, and only homes built more than two years ago can benefit from them. This signals a desire to promote renovations rather than new constructions.
Concrete examples of eligible work
To better understand this VAT reduction, let’s take a few examples of eligible interventions:
Type of work | Examples | Applicable VAT rate |
|---|---|---|
Thermal insulation | Insulation of attics, window replacement | 5.5% |
Heating | Replacement of a conventional boiler with a condensing boiler | 5.5% |
Energy systems | 5.5% |
Each project must be carefully planned to ensure that all eligibility criteria are met to avoid unpleasant surprises during billing.
Conditions to benefit from the 5.5% VAT
For a project to benefit from the reduced VAT, certain conditions must be fully respected. These conditions are crucial to ensure that the VAT reduction is applied correctly.
Eligibility criteria
Here are the specific criteria to be met:
The construction of the home must have been completed for more than two years.
The work must aim to improve energy efficiency.
The materials and equipment installed must meet minimum performance standards.
The work must be carried out by a qualified professional.
It is important to note that if a person decides to purchase materials on their own and handle the installation themselves, the reduced rate will not apply to these purchases. Thus, it is always recommended to consult qualified companies such as Duralex, Thermor, or Atlantic, who will not only execute the work but also provide correct invoices reflecting the applicable VAT reduction.
Obtaining and retaining certificates
To justify the application of the 5.5% VAT, the client must provide a certificate to the contractor. This certificate can be standard or simplified, depending on the nature of the work:
Standard certificate: required for work affecting floor areas or modified volumes.
Simplified certificate: sufficient for work that does not alter the main structure of the home.
These documents must be kept for 5 years to justify compliance with eligibility conditions to the tax authorities.
The other VAT rates applicable to heating work
In addition to the reduced rate of 5.5%, there are other VAT rates that may apply to heating work, depending on their nature. It is essential to be aware of them to choose the best option.
Intermediate rate of 10%
The rate of 10% applies to renovation work that does not directly improve energy efficiency but falls within the framework of improvement, development, or maintenance. For example:
Installation of new tiles or parquet flooring.
Plumbing work, such as replacing sanitary fixtures.
This rate is therefore slightly higher than the reduced rate, but is generally advantageous compared to the full rate.
Full rate of 20%
The normal VAT rate of 20% is applied to most building works, as well as to work carried out in recent constructions less than two years old. This includes:
The construction of a new house.
Extension or elevation work when the surface exceeds 10% of the existing structure.
This taxation illustrates the importance of being vigilant about the classification of work to avoid significant additional costs.
Planning and estimating the costs of heating work
Before embarking on any renovation project, it is essential to estimate the total cost. This includes not only the work itself but also the tax implications related to VAT.
How to make an accurate estimate?
To make an estimate, you can follow these steps:
Evaluate needs: Identify necessary heating work (boiler replacement, insulation, etc.).
Consult professionals: Request quotes from qualified contractors such as Engie or Bosch, who offer solutions tailored to the need.
Compare quotes: Don’t hesitate to ask for several quotes to compare the costs of the work and the VAT rates applied.
Check eligibility: Ensure that the work meets the criteria for the reduced VAT.
Example of cost estimation
Suppose you want to replace your old boiler with a condensing boiler while carrying out insulation work on your attic. Here’s how your initial estimate would be distributed:
Type of work | Estimated cost | Applicable VAT rate | Total cost including tax |
|---|---|---|---|
Boiler replacement | 3,000 € | 5.5% | 3,165 € |
Attic insulation | 4,000 € | 5.5% | 4,220 € |
Total | 7,000 € | - | 7,385 € |
This estimate gives you a clear idea of the total costs to consider, while illustrating the importance of optimizing the work to benefit from the reduced VAT rate.
