Between energy savings and property value, energy renovation is increasingly becoming an investment strategy for French households.

An increasingly economical approach to energy renovation

While environmental concerns remain important, the French are now approaching eco-renovation from a very practical angle: optimizing their expenses.

The desire to reduce energy bills is the primary motivation for 73% of them. This pragmatic approach illustrates the growing importance of economic considerations in renovation decisions.

Improving comfort (51%) and home maintenance (35%) complement these expectations, demonstrating that the desired benefits are both immediate and long-lasting.

What budget do the French allocate to eco-renovation ?

The French report allocating an average budget of €3,634 for their energy-efficiency renovation projects. This amount represents an 8% increase year-on-year, reflecting a gradual rise in these projects’ importance to households.

However, this budget often remains lower than the actual cost of some energy-efficiency renovations, which may explain why some projects remain partial or are postponed.

Does eco-renovation increase the value of your property ?

Beyond energy savings, eco-renovation is also seen as a way to increase the value of real estate.

Nearly a quarter of French people (24%) believe that these renovations can contribute to increasing the value of their property. This perception confirms that these investments are also part of a long-term strategy.

Financial constraints that further limit projects

Despite growing interest in these projects, financial resources remain a crucial factor.

In fact, 47% of French people say they cannot afford the renovations they deem necessary. This figure highlights that the issue is not just the desire to renovate, but also the actual ability to do so.
