Why renovate a house?
Renovating a house is an opportunity to:
- to adapt housing to your lifestyle
- To save energy
- to improve the comfort of occupants
- to increase the real estate value of the property
To adapt the interior to your lifestyle
Your needs are changing, your home must follow suit. Renovating a house means ensuring that every square meter meets your current and future needs.
For example, to adapt your home to your lifestyle, you can:
- Transforming an office into a child's bedroom in order to welcome a new member into the family.
- Open a kitchen to the living room in order to create a larger and more convivial living space.
- Arrange the attic in order to offer a teenager a more independent space or to create an isolated parental suite.
- Create custom storage in order to optimize every corner and declutter living rooms.
At Maison Kyka, we offer a turnkey renovation of your house. Our interior design studio, our project managers and our companions are at your disposal to help you make your home a place to live adapted to your daily life.
To save energy
A house overconsumes if it is poorly insulated or heated by outdated equipment., which weighs on your bills and on the ecological footprint of your home. Renovating a house is therefore an opportunity to take back control of your energy expenses. By targeting the right jobs, you can drastically reduce your expenses while increasing the value of your assets.
Here are the most strategic items to deal with to reduce your energy expenses:
- Roof and wall insulation: according to ADEME, up to 40% of heat can escape through a poorly insulated roof and up to 25% through walls.
- Window insulation : installing double glazing with reinforced insulation helps to reduce heat loss.
- Efficient heating : replacing an old oil or gas boiler with a heat pump or pellet boiler can halve the bill in some cases.
- Home automation : adding a programmable thermostat or connected equipment optimizes the energy consumption of your home.
NOTE
Beyond immediate savings, these renovations also help you stay ahead of upcoming regulations. For instance, since January 1st, 2025, homes with a G energy rating (DPE) can no longer be rented out under the Climate & Resilience Law.
At Maison Kyka, we can help you target the most profitable jobs according to your budget, your consumption habits and the performance of your home.
To improve the comfort and safety of occupants
An old house does not always offer the standards of comfort and safety expected today. Renovating can be justified by the need to create a more pleasant and healthy living environment.
Here are some examples of work that can improve the comfort of a home:
- Installing a more efficient heating system in order to avoid cold rooms and temperature variations from one room to another.
- Review the insulation of joinery, in order to eliminate cold wall sensations near windows or walls.
- Improving interior acoustics by installing sound insulation (walls, floors, ceilings) to gain tranquility in each room.
- Rethinking lighting can have a big impact on the comfort of occupants
In addition to comfort, renovating a house also makes it possible to reinforce the safety of the occupants:
- Updating the electrical installation : in homes built before the 90s, poorly positioned sockets, bare wires or obsolete panels can present a real risk of electrocute or domestic fire.
- Plumbing overhaul : replacing old pipes helps to avoid water leaks and potentially dangerous molds.
- Improving ventilation : an adapted CMV limits humidity problems and protects occupants from indoor pollutants.
- Effective ventilation : a single or double flow CMV protects occupants from indoor pollutants by limiting humidity and improving air quality.
- Securing stairs, balconies or railings : these often overlooked elements can be brought up to standard to prevent falls and domestic accidents.
To increase the value of the house in the real estate market
The charm of the old combined with the comfort of the modern is particularly valued on the real estate market. Provided that the work has been carried out in an intelligent manner, a renovation allows increase the value of a property. It may be more profitable to renovate a house before selling it than to sell it with work to be done.
Here are some examples of renovations that can increase the value of a home:
- Improving energy performance : a good DPE reassures buyers and seduces rental investors, which increases the value of the property.
- Modernizing strategic parts : renovating and furnishing the kitchen or bathroom, the main rooms of a home, often makes it possible to sell at a higher price.
- Modernizing electricity, plumbing, and heating : secure housing that does not require heavy work is easier to sell.
- Take care of the finishes : sustainable materials, harmonious colors, functional layout increase the chances of triggering a crush during a visit.
NOTE
Don’t overestimate certain types of work — it’s better to focus on visible, cost-effective renovations that align with the property’s position on the market.
At Maison Kyka, our team of real estate hunters and interior designers accompanies you in all stages of buying a property and its renovation. Our aim is to help you make the right choices in order to sustainably increase the value of your (future) home.
”I was supported by Maison Kyka in the realization of my project and I am very satisfied with the result! All the teams listened to me and fully understood my expectations. I am delighted to have been supported by the Maison Kyka service and I advise anyone who wants to carry out a tailor-made and innovative real estate project to go for it with them!”
Olivier Dhalluin
What types of work should you do to renovate a house?
Many types of work can be considered when renovating a house:
- Demolition and partitioning
- Thermal and acoustic insulation
- Replacing windows or frames
- Replacing the heating system
- Electrical and plumbing renovation
- Replacing or installing a ventilation system
- Painting ceilings and walls
- Replacing flooring
- Kitchen renovation
- Attic renovation
- Bathroom renovation
Demolition of the existing building (if necessary) and partitioning
To be able to build something new, sometimes you have to deconstruct the old one first. This is why during a renovation, certain parts of the house may be removed, modified, or reorganized to allow for a more consistent redistribution of volumes.
However, it is only a question of removing what is holding back the optimization or modernization of housing.
Some common examples of useful demolition include:
- Knock down a partition to open a kitchen into the living room or expand a living room.
- Remove an old chimney in order to free up space and modernise the layout.
- Dismantling a false ceiling to gain height and clarity.
- Bring down a load-bearing wall when technically possible.
NOTE
Any demolition work — especially if it involves a load-bearing wall or an old structure — should be preceded by a technical assessment to avoid any risk of collapse or structural weakening.
Once the spaces are freed up, partitioning consists of using suitable materials to rearrange the house according to your tastes and needs:
- Drywall (plasterboard type): quick to install, ideal for easily separating two rooms.
- Acoustic partition : recommended to preserve the calm of the rooms.
- Water-repellent partition : used in humid rooms such as a bathroom or laundry room.
- Glass partition : to delimit by allowing light to pass through.
NOTE
These renovations also allow you to conceal electrical wiring, plumbing, or ventilation ducts within the structure.
Thermal and sound insulation
On the thermal side, insulation aims to limit heat loss in winter and to maintain freshness in summer. Here are the main areas to be treated as a priority:
- The attic and the roof : this is where the heat escapes first.
- The walls : they can represent 15 to 25% of losses. They can be insulated from the inside or from the outside.
- The floor : insulating the floor limits the sensations of cold in the rooms on the ground floor.
NOTE
The most commonly used materials include glass wool, rock wool, polyurethane, or bio-based alternatives such as hemp or cellulose wadding.
On the acoustic side, the objective is to reduce noise pollution, whether it comes from outside or from an adjoining room. Several solutions exist:
- Insulate the adjoining walls
- Installing an acoustic false ceiling between two floors of the house
NOTE
Thermal and acoustic insulation often go hand in hand. A good thermal insulator, such as rock wool, also offers excellent soundproofing performance.
Replacing windows and frames
Changing windows and frames is a powerful tool for improving the thermal and acoustic insulation of your home. Old windows, especially single-glazed windows, let in cold, humidity and drafts. The result: energy losses, a rising bill and a feeling of cold even when the heating is on.
Here are the elements to take into account when it comes to windows and frames:
- The glazing : opt for double glazing with reinforced insulation (type 4/16/4) or triple glazing if your house is facing north or in a very cold zone.
- The frames (frames) : aluminum, PVC, wood or mixed (wood/aluminum), each material has its advantages. PVC is economical, wood is noble, aluminum is particularly durable.
- Watertightness : well-installed windows prevent air and water from entering.
- The shutters : replacing or motorizing existing shutters improves both the insulation and the security of the house.
NOTE
To check window airtightness, try the candle test: hold a flame near areas where air might be leaking. If the flame flickers, there's a draft.
In old or listed buildings, pay attention to urban planning rules: certain materials or types of carpentry may be imposed by the Architect of Buildings of France.
At Maison Kyka, we recommend installing windows with excellent energy performance because of their impact on your loads and comfort.
Installation of an efficient heating system
An outdated heating system, poorly regulated or poorly adapted to the configuration of your home is often synonymous with thermal discomfort, energy waste and high bills.
Modern heating equipment and systems consume less, heat better and can be controlled in order to adapt consumption hour by hour, and even room by room.
Here are some examples of solutions that are commonly installed when renovating a house:
- Air/water heat pump : ideal as a replacement for an oil boiler, it supplies a heated floor or existing water radiators.
- Pellet stove : it heats up a large living room quickly and makes it possible to use central heating less.
- Gas condensing boiler : efficient, it can be a good alternative if you are already connected to gas.
- Electric inertia heaters : more efficient than a “toaster” radiator, they provide gentle and constant heat
NOTE
Wherever you live in France, installing solar panels on your roof is an efficient (and cost-effective) way to power your appliances, heat domestic water, and increase your property’s market value.
At Maison Kyka, we help you choose the heating system that best suits your consumption habits and the specificities of your home.
Electricity & plumbing
Behind the walls, what you can't see is just as important as what's obvious.
When renovating an old house, using electricity again allows:
- To improve housing security : an electrical installation that does not comply with the current standard (NF C 15-100) exposes to risks of electric shock or fire.
- To adapt to the uses of our time: an electrical renovation makes it possible to create new circuits, to add sockets (in particular RJ45 for the internet) and to rethink the lighting.
On the plumbing side, here are the most common interventions in a renovation:
- Replacing aging pipes (often made of lead or galvanized steel) that present a risk of corrosion or leaks.
- Optimizing water networks : by changing arrivals and evacuations, you can rethink the layout of the kitchen or bathroom.
- Install economical equipment : thermostatic faucets, dual-flow flush, smart water heater etc...
Ventilation
Ventilation is often the poor part of renovation, while it plays a major role in the comfort and sustainability of your home. A poorly ventilated home accumulates humidity and deteriorates indoor air quality, which is as harmful to your health as it is to your materials.
Improving ventilation makes it possible to renew the air continuously without cooling the interior unnecessarily, to avoid mould (especially in water rooms) and to limit unpleasant odors.
Here are some examples of solutions that are often present in a renovated house :
- Humidity-controlled single-flow VMC : it automatically adjusts the air flow according to the humidity level,
- VMC double flow : it makes it possible to recover the heat from the outgoing air to heat the incoming air.
- Assisted natural ventilation : in some cases, existing ducts can be coupled with air extractors to improve circulation without redoing everything.
Painting ceilings and walls
In renovation, repainting walls or ceilings is a simple and quick intervention that makes it possible to enhance natural light and personalize the rooms according to your tastes.
Here are some signs to know if it's a good time to repaint:
- Paint is peeling, yellowing, or cracking in places.
- Black spots are visible around windows, on the ceiling, or near heat sources.
- Repairs (plugging, partitioning, installing sockets) have left marks.
- You no longer feel in sync with the colors or the overall ambiance of the room
NOTE
In addition to enhancing your interior, repainting also helps protect surfaces.
At Maison Kyka, our painters apply techniques adapted to each space: washable, breathable, matt or satin, always with a high-end finish. With our interior design studio, all you have to do is choose the colors that suit you.
Installing flooring
When renovating a house, the choice of flooring improves comfort, maintenance, acoustics and the perception of space. It is also an opportunity to correct the defects of an old floor: irregularities, squeaks, worn materials or materials not adapted to the use of a room.
Here are some types of coatings that are often preferred, depending on the rooms and needs:
- Semi-solid or laminated parquet : warm, elegant, it is suitable for bedrooms and living rooms.
- Tile : ideal for a kitchen and a bathroom, it has the advantage of being robust and easy to maintain.
- Vinyl or PVC floor : economical, easy to install, it imitates wood or concrete well and is suitable for rooms in which there is a lot of traffic.
- Waxed concrete or resin : trendy in contemporary interiors, it offers a smooth and seamless surface.
- Carpet : appreciated for its acoustic and thermal comfort, especially in the rooms.
NOTE
The choice of flooring should also take heating into account: some types of flooring are more compatible with underfloor heating than others.
Kitchen renovation
The kitchen is a central room in a home, a space where you prepare, share and live. Over time, the original layout no longer always meets your needs. Furniture gets damaged, equipment becomes obsolete, and traffic can become impractical. Renovating allows you to start again on a healthy basis, with a better thought-out organization and sustainable materials.
Here are some examples of work that can be done when renovating a kitchen:
- Replace tall and low furniture with more ergonomic modules, with shock absorbers, sliding drawers or corner storage.
- Change the countertops for a more resistant material: quartz, marble, recycled plastic, etc...
- Rethink the lighting by adding integrated spots or LED strips.
- Modernizing household appliances: built-in oven, induction hobs, silent hood and energy-efficient refrigerator...
- Redo floors and walls: for a kitchen that is easier to maintain (tiling, washable paint, etc...)
NOTE
A modern, well-designed kitchen can have a significant impact when reselling a home, as it gives buyers the impression ofinvesting in a luxury property.
Attic renovation
Renovating the attic of a house allows you to gain more living space, increase the value of your home and create a new living space.
Provided it is properly insulated, well ventilated, and high enough to allow for comfortable circulation, the attic can be transformed into a bedroom, a playroom, an isolated office, or even a master suite with bathroom.
Here are some examples of possible work when renovating the attic of a house:
- Reinforcement or modification of the frame, if it prevents the development of space.
- Thermal (and sometimes acoustic) insulation to guarantee comfort in summer and winter.
- Creation of roof windows or skylights, to bring in natural light.
- Installation of a technical floor, electrical connection, heating, water network according to the uses envisaged.
- Installation of a practical and secure access staircase.
NOTE
To be considered habitable, your attic must have a ceiling height of at least 1.8 meters over 60% of the surface area. Below this, it can be converted but will not be included in the habitable surface measurement (Carrez Law).
Renovation of the bathroom and sanitary facilities
A renovated bathroom improves the comfort of all occupants: it facilitates daily actions, limits the risk of falls and enhances the entire home. It is also an opportunity to install equipment that is more efficient in water and energy.
Here are some examples of frequent work when renovating a bathroom or sanitary room:
- Replacing the bathtub with an Italian shower, more secure and practical, especially for the elderly or children.
- The installation of a vanity unit with integrated storage to optimize the use of space.
- The installation of suspended sanitary ware for easier cleaning and a visually more aesthetic result.
- The upgrading of plumbing and electricity, with waterproof lighting and secure sockets.
- Replacing wall and floor coverings with durable, anti-slip and moisture-resistant materials.
At Maison Kyka, we start each renovation project with a complete study of the existing situation and an analysis of priorities. This strategic step makes it possible to build a realistic schedule, a controlled budget and a clear roadmap for the entire project.
“House Kyka is an incredible experience and team! I am the happy new owner of a property entirely sourced and renovated thanks to Maison Kyka! A first purchase is complicated and scary, so being accompanied under these conditions is simply the best possible experience!”
Jordan Lorho
The 6 stages of a renovation project
A home renovation project involves 6 steps:
- Identification and prioritization of the work to be carried out
- Assessment of the construction site budget (including grants)
- Timely planning of work
- Completion of the necessary administrative procedures
- Craftsman's choice
- Supervision of the site until the work is received
1. List and prioritize the renovation work to be done in the house
To begin with, it is essential to have a clear vision of The initial condition of your home. This first step makes it possible to detect possible structural problems and to measure the extent of the renovation to be expected.
This involves doing a technical state of affairs of the house: roof, walls, floors, electrical networks, electrical networks, plumbing, heating, ventilation, carpentry, etc.
To do this, you can rely on mandatory real estate diagnostics, such as:
- The DPE (Energy Performance Diagnosis)
- Electrical diagnosis
- The gas diagnosis
- Sanitation diagnosis
NOTE
If you don’t have a recent inspection report, it is recommended to call on certified RGE professionals or approved inspectors. These documents can also be used with your bank or a potential buyer.
Once the list of work has been identified, priorities must be established. Not everything can be done at the same time or with the same budget. The objective is therefore to distinguish between:
- The works urgent (roof to be redone, dangerous electrical installation).
- The works structural (rearrangement, creation of openings, insulation).
- The works techniques (heating, plumbing, ventilation).
- The finishes and interior fittings, to be positioned later (if necessary).
This prioritization of work can be supported by an architect or a project manager. Their professional experience helps to avoid mistakes and to imagine design solutions that are not always thought of at the beginning.
2. Define the work budget
A successful renovation starts with a well-planned budget. Start with Distinguish jobs that you can do yourself (painting, small installations, decoration...) of those that require the intervention of qualified professionals (structural work, electricity, plumbing, insulation...).
Then, have it done several quotes per trade. Compare the proposals, check that the services are well detailed item by item and make sure that the equipment offered meets your expectations in terms of quality and durability.
NOTE
A good quote isn’t necessarily the cheapest one, but the one that is precise, transparent, and consistent with the actual scope of the work. Encourage the contractors you contact to visit the property.
Include in your budget:
- The cost of technical diagnostics and possible preliminary studies.
- The fees of an architect or a contractor if you are accompanied.
- A safety margin (5 to 15%) for unexpected construction site events.
- Expenses related to administrative procedures, insurance or connections.
- The financial aid you can apply for (see lower).
Once the budget is estimated, you can prepare your financing plan. Some banks require a detailed description of the work, signed quotes and proof that the companies selected are well insured and qualified. The clearer your file is, the more likely you are to obtain, under good conditions, a works loan or a real estate loan including renovation.
ADVICE
If you need to make budget trade-offs, it’s better to prioritize major and energy-related work (electrical upgrades, insulation, roofing, joinery, heating).
At Maison Kyka, we help you establish a realistic budget, adapted to your project and your financing capacities. We work transparently to allow you to make informed choices, from the very first design phases.
”My experience with this team has been exceptional. My architect fully understood my expectations and the project team was always attentive. My project was delivered on time and the end result is fantastic. I am very satisfied with the service received.”
Lyrod Levy
3. Plan the different types of work over time
In a renovation project, the order of work is important and a well-thought-out schedule makes it possible to avoid unnecessary interventions, backlogs and delivery delays.
In general, home renovation generally consists of three main phases, ranging from more structural At more aesthetic :
- The structural work corresponds to work that affects the structure of the building (demolition, masonry, masonry, roof, framework, opening of load-bearing walls, sanitation, etc.).
- The second work includes technical elements such as electricity, plumbing, insulation, heating, carpentry or partitions.
- The finishes include painting, installing custom flooring and furniture, decoration, etc...
NOTE
Poor planning of renovation work can be costly. For example, painting before updating the electrical system or installing insulation may force you to start over.
Please note, renovation project planning must also take into account:
- Material delivery times, which may vary depending on the suppliers and the nature of the products (custom tiling, equipped kitchen, exterior carpentry, etc.).
- The availability of the various trades in order to avoid harmful overlaps or periods of inactivity.
- Your own constraints: date of move in, occupancy of the home during the work, bank deadline...
At Maison Kyka, a renovation project manager ensures coordination between the construction manager, the technical director, the contractors and the team dedicated to the purchase of the materials and equipment necessary for the smooth running of the site. Thus, each stage of the project goes on without a hitch, on time and in compliance with the specifications.
4. Carry out administrative procedures
A common mistake is to start work without permission, thinking that it will go unnoticed. However, many renovations require a declaration at the town hall, or even a building permit. Anticipating these procedures saves you from sanctions, delays or redoing work.
The type of authorization depends on the nature and extent of the work:
- One prior declaration of work is generally sufficient for projects that do not modify the structure of the house (installation of windows, renovation of the facade, installation of a small pergola or carport, etc.).
- One building permit is mandatory for any extension of more than 20 m², elevations, changes of destination (e.g. transforming a garage into a living room) or certain works impacting the supporting structure.
NOTE
Since 2017, if the renovated house has a surface area of 150 sq. m or more, hiring an architect is mandatory. Additionally, a house located in a protected area, a heritage zone, or near a historic monument may require approval from the Architect of the Buildings of France (ABF). This entails constraints on materials, colors, and facade modifications.
In order to avoid any unpleasant surprises, it is recommended to call on a professional who knows the local urban planning rules (PLU) and who ensures that all the documents are in order before the start of the construction site.
5. Choosing qualified and certified artisans
Renovating a house can mobilize many trades: mason, roofer, carpenter, carpenter, carpenter, drywall, plumber, heating engineer, painter, tiler... and sometimes artisans with more specific skills such as a waterproofer, an ironworker or an installer of photovoltaic panels.
To ensure that the work is carried out according to the rules of the art, several checks are required before signing the estimate from a craftsman:
- The legal existence of the company (Kbis extract, SIRET number).
- A valid ten-year insurance.
- The RGE label (Recognized Environmental Guarantor) for works eligible for State aid (insulation, heating, windows, etc.).
- Verifiable references : photos of achievements, customer reviews, worksites that can be visited.
NOTE
Trust is just as important as technical skill. A reliable contractor provides a detailed quote, takes the time to communicate with you, respects agreed deadlines, and remains reachable throughout the entire project.
At Maison Kyka, we collaborate with our own team of companions, selected for the quality of their work, their transparency and their commitment. This allows us to carry out renovation work with greater autonomy, a higher level of requirements and to limit the risks of unforeseen events.
6. Follow the progress of the construction site until delivery
Before the start of the work, remember to prepare the premises: clear the rooms concerned by the work, protect the furniture that remains on site or the parquet.
During the construction site, organizing regular meetings makes it possible to:
- Validate the completed steps before moving on.
- Verify the conformity of materials and finishes.
- Answer the questions of the artisans or specify certain details.
- Ensure that the site meets the deadlines agreed upon at the start.
- Take photos of technical elements (networks, insulators, structures) before they become invisible.
NOTE
Photographing the hidden elements of the renovation (electrical wiring, ductwork passages, insulation behind partitions) can be very useful in case of disputes or future work.
The final stage of a renovation project is Acceptance of work. Before signing the acceptance report, take the time to inspect everything: proper functioning of the equipment, condition of the finishes, compliance with the initial plans. In case of doubt, you have the right to express reservations and request the correction of non-compliant points before final validation.
At Maison Kyka, we assign a dedicated project manager, which ensures the link between you, the construction supervisor, the contractors and the suppliers. We keep you informed of the progress of the construction site, step by step, so that you can follow your project with peace of mind.
“I have just purchased my second property and Maison Kyka took care of everything from A to Z. From research to work, the architect managed to transcribe my need as I imagined but better! The team is responsive and it allowed me to free up time for myself and to leave the work part with complete peace of mind! Thanks again, I highly recommend!”

Assistance available for renovating a house
The renovation of a house may be eligible for various aids:
- MaPrime Rénov'
- MaPrimeRenov' Serenity
- The eco-loan at zero interest
- Energy certificates
- A VAT rate reduced to 5.5%
- Tax arrangements (for houses classified or located on a protected site)
MaPrime Rénov'
MaPrime Rénov' is the best known aid to finance energy renovation work. Set up by the State, it is open to all owners, occupants or lessors, with no resource requirements but with amounts that vary according to your income and the nature of the work.
This assistance covers a wide range of works, provided they are carried out by companies with the RGE label (Recognized Environmental Guarantor). This includes, among others:
- The insulation of walls, attics and floors.
- The replacement of a heating system with a more efficient solution (heat pump, pellet boiler, etc.).
- The installation of double flow ventilation or solar thermal panels.
MaPrimeRénov' primarily finances so-called efficient renovations, that is to say the projects that allow your home to significantly improve its energy performance.
Some expenses are therefore not covered by MaPrimeRénov', such as surface extensions, purely aesthetic work or renovations without an energy objective.
MaPrimeRenov' Serenity
MaPrimeRenov' Serenity is a reinforced version of MaPrimeRénov'. It is intended for owner-occupants with modest or very modest incomes who want to undertake a global renovation of their homes.
To qualify, you must:
- Be the owner occupying a home that is more than 15 years old, located in mainland France or overseas.
- Not having benefited from a zero interest loan in the last 5 years (with some exceptions).
- Achieve a bouquet of works Allowing you to win at least 35% energy savings.
- Call on RGE professionals for carrying out the work.
The zero-interest eco-loan
The zero interest eco-loan or”eco-PTZ”, is an interest-free loan that allows you to finance your energy renovation work. It is awarded by partner banks of the State, and reimbursable over a period of up to 20 years.
This loan is open to all owners, occupants or lessors, with no resource requirements. It only concerns main residences built over two years ago, located in mainland France or overseas.
The amount of the loan granted depends on the number of work stations carried out:
- Up to €15,000 for a single station (e.g. attic insulation only).
- Up to €25,000 for a package of two seats.
- Up to €30,000 for three or more positions, or for a global renovation.
- Up to 50,000€ if you carry out a global renovation that allows an energy gain of 35%.
NOTE
The eco-zero interest loan (eco-PTZ) can be combined with MaPrimeRénov’.
Energy saving certificates
Les energy savings certificates (CEE) allow you to finance part of your work in the form of bonuses, paid directly or via partners.
This help is available to all households with no income requirement, although the amounts are higher for modest or very modest households.
Concretely, the amount of the bonus depends on:
- Of the type of work undertaken.
- Of the treated surface.
- Household income level.
NOTE
The Energy Savings Certificates (CEE) can be supplemented by the 'Coup de pouce énergie' scheme, which can provide up to €4,000 to finance the replacement of an old heating system (source : https://www.ecologie.gouv.fr/dispositif-des-certificats-deconomies-denergie).
VAT reduced to 5.5%
As part of an energy renovation, some works benefit from a VAT reduced to 5.5% instead of the standard rate of 20%.
This reduced rate VAT only applies to homes completed more than two years ago, whether they are occupied by the owner or rented as a primary residence.
Here are some examples of jobs where 5.5% VAT is applicable:
- Thermal insulation work (attics, walls, walls, floors, roofs).
- Installation of high-performance exterior carpentry (double or triple glazing).
- Installation or replacement of a more economical heating system (condensing boiler, heat pump, wood stove, etc.).
