Energy performance diagnostics: how to improve your heating in 2025?
In 2025, the importance of the Energy Performance Diagnosis (DPE) has never been more crucial. As we become increasingly aware of environmental issues, the DPE positions itself as a key tool for assessing the energy consumption of housing. Whether you are a homeowner wishing to sell or a tenant wanting to understand your charges, the DPE guides you towards better energy efficiency. So, how can you improve your heating system while meeting DPE requirements? This article will provide you with answers, practical solutions, and tips to optimize your energy consumption and increase the value of your property.
What is the purpose of the DPE?
The DPE is an essential document that assesses the energy performance of a property. It assigns a grade to your home, ranging from A for very efficient homes to G for those consuming a lot of energy.
This diagnosis is now required for any sale or rental of property in France, making both owners and tenants more aware of energy issues and their environmental impact. In 2025, this awareness is more important than ever, as citizens are encouraged to adopt more sustainable practices.
Here is a summary table of the DPE categories:
Class | Energy performance |
|---|---|
A | Very efficient |
B | Efficient |
C | Fairly efficient |
D | Moderately efficient |
E | Poorly efficient |
F | Energy-intensive |
G | Very energy-intensive |
In this context, a well-rated property not only allows for reduced energy bills, but also contributes to the fight against climate change. At the end of the DPE, the owner is also able to better target improvements to optimize energy consumption.
How is it calculated?
The DPE relies on numerous criteria that allow for the evaluation of energy performance, including:
Primary energy consumption: This criterion includes the different energy sources used, such as electricity, gas, fuel oil, or other fuels.
Greenhouse gas emissions: This factor is crucial for assessing the environmental impact of your home and its contribution to global warming.
Thermal insulation: Good insulation is essential to avoid heat loss, thereby reducing energy consumption.
Heating and hot water production equipment: The efficiency of these systems directly impacts the score assigned to the DPE.
To understand the importance of these criteria, let’s take the example of two similar properties with differences in insulation and heating equipment. The first property, well insulated and equipped with a heat pump, could receive a B score, while the second, poorly insulated with old radiators, could fall to a D or E score. This contrast underscores the importance of investing in efficient heating solutions.
It is possible to reduce one's impact through improvements in energy efficiency. This is an investment to consider, especially with the aids offered by organizations such as EDF, Engie, or TotalEnergies that can lighten the initial cost.
An increasingly strict regulation
Since the DPE reform in 2021, the responsibility of owners regarding the information contained in the diagnosis has been greatly increased. In 2025, this trend is strengthening: progressive measures now prohibit the rental of properties classified F and G. The aim is to force owners to improve the energy performance of their properties to combat energy poverty.
Here are the main consequences of these new regulations:
Rental prohibition: Properties classified F and G can no longer be rented. This pushes owners to renovate to remain in the real estate market.
Financial incentives: To support improvement works, various aid schemes such as those offered by Energie Partagée are available, allowing for a reduction in renovation costs.
Awareness-raising: This new legislation also informs tenants, who may choose to prioritize better-rated homes to reduce their bills.
In light of these challenges, it is important for owners to look to the future. In a few years, all homes will have to meet strict energy efficiency standards. To remain competitive in the real estate market, investing in the improvement of energy performance must become a priority.
How to improve your DPE?
Improving your DPE score is not just about legislation, it is also an opportunity to save in the long term. Here are several avenues for improvement:
Thermal insulation: Investing in the insulation of walls, roofs, and windows is essential. Good insulation can significantly reduce heat loss.
Installation of an efficient heating system: Replacing old boilers with modern and efficient models can provide considerable energy savings. Opt for systems like those from Izi by EDF or condensing boilers.
Use of renewable energies: Installing solar panels, heat pumps, or turning to energy suppliers like MeilleurSolaire can contribute to a better DPE while reducing your environmental impact.
Replacement of energy-intensive equipment: Replacing old heating or air conditioning devices with energy-efficient alternatives is fundamental. This not only improves the DPE but also reduces energy bills.
It is also wise to seek financial aids to ease the cost of renovations. Organizations like Dalkia and other local initiatives offer grants and zero-interest loans specifically for energy renovations.
For those doubting the profitability of investments, comparing initial costs with energy savings made in the long term, it is clear that these renovations are worth it. For example, switching from a conventional boiler to a heat pump may represent a higher initial investment, but savings on bills and the resale value of your property increase significantly.
