Global renovation: how to combine assistance to improve insulation and heating in 2025?

The energy transition is at the heart of the concerns of French households in 2025, especially for those living in old or notoriously energy-consuming homes. With rising energy bills, it has become essential to find effective solutions to improve the insulation and heating of one’s home. Thus, many financial aids have been put in place to support renovation projects. In this article, we will explore how to combine these aids, such as MaPrimeRénov', the eco-zero-interest loan, and many others, while considering the concept of global renovation.

Understanding global renovation and its stakes

Global renovation is a comprehensive process aimed at transforming a home through various interventions, including insulation and heating work. For a successful large-scale renovation project, it is crucial to understand the different aspects that compose it.

Definition and characteristics of a large-scale renovation

For a renovation to be considered large-scale, several criteria must be met. The first characteristic lies in its content: at least two types of thermal insulation interventions must be realized. Moreover, if an oil heating system is replaced, it must also be part of the work. The second characteristic is related to the expected result: the goal must be to achieve a gain of at least two energy classes, according to the evaluation of the energy performance diagnosis (DPE).

  • Necessary interventions: Attic insulation, wall insulation, heating system change, ventilation.

  • Objective: Improve the comfort of the home and reduce energy bills.

Who is the large-scale renovation aimed at?

It is important to emphasize that large-scale renovation is not reserved for certain types of housing. Every home can benefit from it, although this type of project is more common for homes classified as F or G. These homes, often referred to as "thermal sieves," have concrete needs for work to achieve significant energy savings.
