By 2025, energy renovation will be a major challenge for reducing energy bills and improving the comfort of French homes. Faced with the constant rise in energy costs, many homeowners are looking for financing solutions for their energy renovation work .
The PTZ (Zero Interest Rate Loan) represents an exceptional opportunity to finance these projects without incurring bank interest. This government program facilitates access to energy performance improvements for all eligible households. Discover in this article the conditions for obtaining it, the procedures to follow, and the advantages of this financing, supported by professionals like the Reno firm in Paris, specializing in interior design and renovation.
PTZ work conditions: the essential eligibility criteria to know
Access to a zero-interest home improvement loan depends on specific criteria established by the French government. These conditions concern both your personal situation and the characteristics of your home.
Resource conditions for the zero-rate loan for work
The borrower’s income determines eligibility for the eco-PTZ works program. The administration calculates these ceilings based on your household’s reference tax income. This amount appears on your most recent available tax notice.
The geographic area of your primary residence directly influences these income thresholds. Zones A, A bis, and B1 correspond to the areas with the most pressure on the real estate market. In contrast, zones B2 and C include less urbanized municipalities.
However, slightly exceeding these limits does not automatically exclude your application. Some banks agree to review applications that exceed the limit on a case-by-case basis.
Criteria for housing eligible for the PTZ renovation
Your property must meet several conditions to qualify for renovation financing. First, the property must have been your primary residence for at least two years. This rule applies to both owners and future buyers.
The age of the building is a fundamental criterion for the existing PTZ scheme. Your home requiring energy renovation must have been completed more than two full years ago. This condition clearly distinguishes between new construction and energy renovation.
The initial energy performance of your property determines which work is eligible for financing. A recent energy assessment establishes this housing energy classification. Consequently, properties classified F or G benefit from priority access to aid, particularly to improve their thermal insulation .

What work is financed by the PTZ in 2025 ?
The PTZ eco loan covers a wide range of energy efficiency improvement projects. These interventions all aim to reduce the energy consumption of your existing home.
List of works eligible for the zero-rate loan
Thermal insulation is the top energy renovation project funded by this program. This category includes wall, roof, and lower floor insulation. Similarly, the insulation of unused or converted attics benefits from this advantageous financing.
Efficient heating systems are a top priority in the eco PTZ program. Replacing an old boiler with a heat pump is included in this program. Installing a pellet stove or biomass boiler is also eligible.
Domestic water production using energy-efficient equipment is one of the subsidized projects. Thermodynamic water heaters and solar tanks meet these technical requirements. These installations significantly reduce your annual energy bill .
High-performance exterior joinery improves the airtightness of your building envelope. Replacing old windows with double or triple glazing optimizes insulation. This intervention significantly limits winter heat loss.
Energy performance improvement works
The main objective of the system is to improve the energy performance of your main residence. Your work must allow a minimum energy gain of 35% compared to the initial state. This requirement guarantees the real efficiency of the investments made, particularly important in view of the new DPE regulations .
Some essential work can be financed simultaneously with the main interventions. For example, electrical renovations often accompany the insulation of interior walls. Similarly, plumbing revisions are necessary when changing the heating system, especially in the context of an electrical renovation of an old house .
The equipment and materials used must meet the required certifications. The RGE (Recognized Environmental Guarantor) label is required for all companies involved. This qualification ensures compliance with current technical standards.
Maximum amount of PTZ renovation work
The maximum amount of the zero-interest loan depends directly on the composition of your tax household. This amount varies between 15,000 euros for a single person and 50,000 euros for a large family. However, certain complex transactions may justify higher amounts.
Combining this with other government aid significantly optimizes your renovation financing plan. MaPrimeRénov’, Energy Savings Certificates, and local aid combine perfectly. This strategy can cover up to 90% of the total cost of your project, as detailed in our guide on how to combine renovation financial aid .
At Reno, we provide accurate quotes to maximize your eligibility for the various grants available. Our in-depth knowledge of energy renovation grants allows us to optimize the financing of your energy renovation. We also assist you in choosing the most efficient technical solutions.
How to apply for a PTZ work?
Preparing a PTZ work file requires careful and methodical preparation. This administrative process determines whether you will receive financing for your work.
Administrative procedures for obtaining the PTZ renovation
Your bank is the first point of contact when applying for an eco-PTZ. The lending institution will verify your eligibility based on current income criteria. It will then examine the technical coherence of your energy-efficient renovation project.
The complete application includes several documents essential for processing your application. You must provide your last three pay slips and your most recent tax notice. Proof of home insurance and floor plans are also required.
The detailed estimate for eligible work must be prepared by RGE-certified professionals. This document specifies the exact nature of the work and its estimated cost. It also indicates the expected energy performance after completion of the work. For more information on financing options, see our complete guide to the PTZ energy renovation loan .
Processing times generally vary between three weeks and two months, depending on the institution. During this period, your banker may request additional information or supporting documents. The final response will be sent to you by registered mail with acknowledgment of receipt.
Approved PTZ lending organizations
Only certain banks are authorized to distribute the zero-interest eco loan for renovations. These institutions have signed a specific agreement with the French government for this scheme. They are committed to complying with the conditions of granting the loan as defined by the regulations.
Negotiating repayment terms remains possible despite the zero annual percentage rate. You can also discuss the term of your loan based on your financial capacity. This period generally extends between ten and fifteen years for this type of financing.
Your existing banking relationship often has a positive impact on the review of your PTZ application for old renovations. Institutions favor their loyal customers when granting this advantageous loan. However, nothing prevents you from applying to several banks simultaneously.
Declaration of honor and commitments
Obtaining financing places you under a legal obligation to the lending institution and the government. In particular, you must strictly adhere to the conditions of occupancy of your primary residence. This obligation lasts for the entire duration of the loan repayment.
Completing work within the specified timeframe is an absolute contractual obligation. Generally, you have three years to complete all planned work. This deadline may be extended in exceptional circumstances upon a reasoned request to your bank.
Random inspections may be conducted to verify compliance with your situation. These inspections concern both the actual occupancy of the property and the completion of the work. Failure to comply with the commitments will result in the immediate repayment of the borrowed capital.
Reno, the renovation specialist company, will assist you in the complete preparation of your zero-interest loan application. Our administrative expertise greatly facilitates your dealings with funding agencies. We also ensure strict adherence to the completion schedule to preserve your financial assistance.
Other aid for energy renovation in addition to the PTZ
Before optimizing your financing strategy, it’s important to understand the main types of assistance available and their eligibility requirements. Each program has its own eligibility criteria, which can be combined with the PTZ (Price-Free Loan) for work.
MaPrimeRénov’ is the leading public aid program for financing your energy renovation work. This grant is available to all homeowners regardless of income, but its amount varies depending on your income. The ceilings range from 25% to 90% of the cost of the work, depending on your income category (blue, yellow, purple, or pink).
Energy Savings Certificates (ESCs) offer incentives paid directly by energy suppliers. This assistance applies to all homeowners and tenants, regardless of income. The amount depends on the nature of the work and the energy savings generated. These incentives can easily be combined with other public programs.
The National Housing Agency (ANAH) offers specific subsidies to homeowners with modest and very modest incomes. The “Habiter Mieux Sérénité” program finances up to 50% of the work, with a ceiling of €15,000. This grant requires a minimum energy gain of 35%, similar to the PTZ (Private Interest Loan) for work.
Local authorities are developing their own energy renovation support programs. These grants vary considerably depending on your municipality, department, or region. Some authorities offer preferential-rate loans or lump-sum grants for specific equipment.
Optimizing your financing: PTZ and other work assistance
The optimal financing strategy intelligently combines the PTZ with other available aid schemes. This comprehensive approach maximizes your subsidy opportunities while respecting the regulatory constraints of each scheme.
Combining PTZ and MaPrimeRénov’ to maximize aid
Combining the PTZ works loan with MaPrimeRénov’ is the most advantageous strategy for financing your energy renovation. These two schemes complement each other perfectly and together can cover up to 90% of the total cost of your eligible work.
The conditions for combining funds require complete consistency between the two aid application files. Your work must appear on the eligibility lists of both programs simultaneously. In addition, the companies involved must have RGE certification to maintain this funding.
Calculating the total amount of aid available depends on your income, the composition of your household, and the nature of your renovations. For a family of four in zone B1, the total amount can reach €35,000 in PTZ (Private Interest Rate) plus €10,000 in MaPrimeRénov’ (MaRenovation Prime). This combination generally covers the entire cost of a complete energy renovation.
The optimal financing strategy requires seamless coordination of deadlines and administrative procedures. Both applications should be submitted simultaneously to avoid inconsistencies. Our expertise at Reno facilitates this complex coordination and maximizes your chances of approval.
Additional loans and banking solutions
The classic eco-PTZ differs from the PTZ for works in its scope and eligibility conditions. The former exclusively finances energy improvement work, while the latter can include other types of interventions. This distinction directly influences your overall financing strategy.
Traditional home improvement loans effectively complement the zero-interest loan (PTZ) when your needs exceed the authorized limits. These traditional bank loans cover projects not eligible for public schemes. For example, renovations or comfort improvements can be financed through these complementary solutions.
Negotiating comprehensively with your bank optimizes the overall terms of your financing plan. You can obtain preferential rates on additional loans in exchange for the PTZ loan. This comprehensive approach significantly reduces the total cost of your renovation project.
PTZ work and energy performance: maximize the impact of your investment
The zero-interest loan for renovations is part of a comprehensive approach to improving the energy performance of your home. To optimize your investment, you need to understand how to coordinate zero-interest loan conditions with your energy-saving goals and the selection of suitable professionals.
PTZ eligibility and energy savings: a strategic approach
PTZ eligibility is based on a fundamental principle: your PTZ-eligible work must generate significant energy savings. This requirement transforms your project from a simple renovation grant into a genuine investment in your assets. Whether you’re planning an apartment renovation in the capital or a house renovation in the provinces, this rule applies uniformly.
PTZ financing prioritizes projects with a high energy impact. Thermal insulation, replacing heating systems, and improving joinery are the cornerstones of this strategy. These projects sustainably reduce your energy bills while adding value to your property.
The combination of PTZ works and MaPrimeRénov’ significantly optimizes your budget. This synergy allows you to finance up to 95% of your projects while respecting the PTZ conditions. The Paris Reno interior design firm has a thorough understanding of this complex relationship between the various aid schemes.
Professional support and regulatory compliance
The success of your project requires expert support to navigate the requirements of a zero-interest home improvement loan and energy performance objectives. RGE-certified professionals guarantee the technical compliance essential to maintaining your financial assistance.
Choosing a specialized Paris interior design firm like Reno facilitates the coordination between aesthetic design and energy performance. This technical expertise optimizes the use of your renovation financing while creating harmonious and energy-efficient living spaces.
Expert advice for the success of your PTZ works project
The success of your PTZ construction project depends on a rigorous selection of professionals and methodical planning of the project. These technical aspects determine the compliance of your application and the preservation of your financial aid.
Choosing the right professionals for your PTZ work
The importance of RGE certifications cannot be underestimated in the context of the PTZ works loan. This qualification guarantees the technical compliance of your work and determines the continuation of your financial aid. Only companies with this certification can carry out work eligible for public funding.
Selecting qualified companies requires a thorough check of their references and technical expertise. Choose professionals who specialize in your type of project and have extensive experience in energy renovations. Recommendations from previous clients and similar projects are excellent indicators of quality.
Coordinating various trades is a major challenge in comprehensive renovation projects. An experienced project manager efficiently coordinates the work of each specialist according to an optimized schedule. This professional coordination limits delays and avoids costly defects, which is particularly important with an architect specializing in renovations .
Reno customer testimonial: “Thanks to Reno’s support for our apartment renovation in the 16th arrondissement, we were able to benefit from the PTZ and optimize our work budget. Their technical and administrative expertise saved us valuable time in our procedures.”
Construction site planning and monitoring
The optimal phasing of the work respects technical logic while maximizing the energy efficiency of each intervention. Insulating the envelope generally precedes replacing the heating system to properly size the equipment. This logical sequence optimizes final performance and limits rework.
Meeting PTZ deadlines is an absolute contractual obligation to preserve your financing. A detailed schedule with precise milestones allows you to monitor progress and anticipate potential delays. Weather conditions, supply times, and the availability of tradespeople all influence this schedule.
Quality control and acceptance of work are carried out according to a rigorous protocol to validate technical compliance. Each intervention is subject to verification before the next phase of the project. This method prevents hidden defects and guarantees the final quality of your energy renovation.
PTZ work conditions: what you need to know to optimize your renovation
The PTZ works loan represents an exceptional opportunity to finance your energy renovation project without incurring interest. This government program facilitates access to energy-efficient improvement work for all eligible homeowners. However, obtaining this aid requires compliance with strict conditions regarding your income and housing.
The success of your project depends largely on the quality of your application and the choice of professionals. RGE-certified companies guarantee the technical compliance necessary to maintain your grants. Additionally, expert project coordination optimizes deadlines and preserves your projected budget.
Combining this with other programs like MaPrimeRénov’ significantly maximizes your financing options. This strategy can cover up to 95% of the total cost of your eligible work. However, this approach requires in-depth knowledge of current regulations.

FAQ: PTZ works conditions
1. Can I benefit from the PTZ work loan for a condominium apartment?
Indeed, apartment owners can obtain a zero-interest loan for their private renovations. However, only work carried out in your personal home is eligible for financing. Work on common areas is covered by other schemes specific to co-ownerships.
Your interior thermal insulation, the replacement of your woodwork, or the installation of your individual heating system all fall within this framework. However, the renovation of the facade or collective roof requires different types of assistance. The National Housing Agency offers tailored solutions for these collective interventions.
2. What is the maximum time limit for completing the work after obtaining the PTZ?
Regulations generally allow three full years to complete all eligible work. This period begins on the date you signed your PTZ eco loan agreement. However, certain exceptional circumstances may justify an extension of this deadline.
Delays due to business disruptions, prolonged inclement weather, or technical changes may require an extension. Your bank will consider these requests on a case-by-case basis based on the justification provided. However, plan ahead, as extensions are never automatic.
3. Is the PTZ works loan compatible with a rental investment?
No, the eco-PTZ works loan exclusively finances improvements to your current primary residence. This condition of personal occupancy is an absolute prerequisite for the government scheme. Consequently, rental or secondary properties are formally excluded from this financing.
However, other financing solutions for renovation work exist for rental investments. Traditional bank loans or certain tax exemption schemes can support these projects. The renovation specialist company Reno can advise you on these alternatives based on your situation.
4. What happens if I sell my home before the end of the PTZ?
The early sale of your primary residence automatically results in the full repayment of the outstanding principal. This contractual obligation is explicitly stated in your zero-interest eco loan agreement. No repayment schedule can be maintained after the sale of the property.
However, certain exceptional situations may deviate from this general rule. Death, disability, or forced job transfer constitute cases of force majeure. These circumstances are subject to special review by your lending institution.
5. How to prove energy improvement for the PTZ works?
A pre- and post-renovation energy audit objectively establishes the improvement in your home’s energy performance. This assessment compares the initial theoretical consumption with the expected performance after renovation. A minimum energy gain of 35% must be clearly demonstrated.
Detailed invoices from RGE companies and equipment conformity certificates complete this technical file. These documents prove that the work eligible for financing has actually been completed. In addition, they demonstrate compliance with the required performance standards.
6. Can I use several companies for my PTZ work?
Absolutely, you can contact different specialized companies depending on the trades involved in your project. However, each contractor must have RGE certification in their field of expertise. This requirement guarantees technical quality and preserves your eligibility for aid.
Coordination between various professionals requires rigorous organization to meet deadlines. An experienced project manager can oversee the entire project and ensure technical consistency. This approach limits the risk of delays and optimizes the overall quality of your renovation.
