Even though insulating a home requires a significant budget, it provides multiple significant advantages. This type of investment allows households to save energy. That’s not all; it also provides them with optimal thermal comfort both in winter and summer.
To encourage them to insulate their homes, there are many subsidies from the State and private companies that reduce expenses.
Before asking yourself: can you insulate an exterior wall yourself, it is necessary to inform yourself about the various available aids. If you meet all the conditions, you will be able to benefit from them.
📋 In brief: Personally, I consider insulation to be the number one lever to reduce bills because MaPrimeRénov’ can finance up to 80% of the cost of work for the most modest households. My opinion is that one must act strategically by combining State aids with energy savings certificates. In 2026, this concrete approach allows you to immediately gain thermal comfort while enhancing your property’s value.
What are the State aids for insulation in 2026?
✅ Advantages
- Immediate reduction of the remaining balance to pay.
- Possible combination between several schemes.
- Enhancement of the property’s DPE label.
🔍 Drawbacks
- Often complex administrative files.
- Variable payment delays for bonuses.
Just like roof and wall repairs, their insulation is very useful in preventing heat loss. The work helps to sustainably limit energy consumption.
Despite their costly price, the investment will be financed by several government aids, but also by countless private actors.
🌍 Did you know? According to ADEME data, about 30% of heat loss in an uninsulated house occurs through the roof. It is the most cost-effective area to insulate first.
MaPrimeRénov is among the well-known State subsidies. This public aid is intended for all households. However, it should be noted that the amount available will be proportional to their income.
As for the CEE or Energy Savings Certificates, this scheme constitutes aid from the private sector also related to insulation work.
The Monexpert Energy Bonus was born from the CEE requiring energy suppliers and fuel sellers to reduce their customers’ energy consumption. The goal is to be able to subsidize insulation work.
Besides that, individuals have the option to benefit from the ANAH aid called MaPrimeRénov Sérénité. They can also take advantage of the Eco-PTZ or zero-interest eco-loan, Action Logement aids, the renovation advance loan, the energy voucher and the reduced-rate VAT on works.
📍 My experience: In October 2024, I helped a neighbor insulate his lost attic for a remaining cost of only 210 euros after deduction of bonuses. We spent two afternoons comparing RGE quotes and preparing the administrative file. The lesson learned is that good preparation upstream avoids losing thousands of euros in subsidies due to simply forgetting a supporting document.
Who is eligible for 1 € insulation in 2026?
1 € insulation is defined as a commercial offer dedicated to individuals. It encourages them to carry out energy renovation of their home. By calling on a professional, the cost of their intervention will subsequently be paid by CEE.
It is important to specify that this scheme ended on July 1st, 2021. However, your work remains eligible for MaPrimeRénov and the Energy Bonus.
Moreover, the offer is not addressed to just anyone. There are income ceilings determining eligibility for the system. For example, a household of 2 people living in Île-de-France must not have a taxable income exceeding 30,225 euros to benefit from 1 euro insulation.
To go further, I advise you to check if insulating an exterior wall yourself is an authorized option to receive aid. Knowing how to transform a house into a BBC also helps anticipate future energy standards. Finally, discovering the best exterior insulation will help you choose the right materials for your project.
What works are covered by ANAH 2026?
ANAH or National Housing Agency is a public institution that finances individuals planning to improve the energy performance of their housing.
If you wonder how to benefit from ANAH aids, know that the concerned house must be a primary residence. Also, it must be at least 15 years old. At the time of requesting aid, you must not have started the energy renovation work yet.
ANAH offers you financial aid to subsidize wall insulation, installation of double-glazed windows, attic insulation, replacement of heating equipment, installation of a double-flow ventilation system, conducting an energy audit or diagnosis, and global renovation.
⚠️ Misconception: Believing that 1 euro insulation still exists. This scheme was removed to limit poor workmanship. Today, aids are proportional to your income, but there remains always a minimum self-financing part.

You can similarly enjoy a 5.5 % VAT reduction. This aid applies not only to main residences but also to secondary ones. Otherwise, there is a property tax exemption which can be partial or even total.
