The cost of an apartment renovation in 2025: Everything you need to know
Renovating an apartment is an exciting step, but it requires serious preparation. In 2025, labour and material prices continued to change, particularly with the impact of new energy standards. The budget can therefore vary considerably depending on the type of renovation envisaged, the surface area of the property and the finishes chosen.
Let us discover together a clear estimate of the costs of an apartment renovation to help you anticipate and avoid bad surprises.
1. The different levels of renovation and their costs
Light renovation (refreshment)
This category concerns simple work that aims to give a young shot back to the apartment without touching the structure. It is ideal if the property is already in good general condition but lacks modernity.
Examples:
- Paint walls and ceilings,
- Place a new floor (floating floor, tiled flooring),
- Replace some plumbing equipment (robinetry, toilet),
- Small electrical repairs (takes, switches).
👉 Estimated budget: between 200 and 500 €/m2.
Complete renovation
Here, it is no longer just a matter of refreshing, but of bring the apartment up to standards and modernize each room. Complete renovation often includes:
- The total repair of electricity,
- Plumbing (replacement of old pipes, creation of new water points),
- The modernization of the kitchen and bathroom,
- Replacement of floors, paints and sometimes interior carpentry.
👉 Estimated budget: between 800 and 1,200 €/m2.
This option is most common when buying an old apartment to be converted into a modern and comfortable accommodation.
Heavy renovation
Heavy renovation involves structural work and a major overhaul of housing. It is often necessary in very old, degraded or poorly insulated apartments. This includes:
- Beat or modify partitions (or even touch a carrier wall with engineering validation),
- Complete insulation (walls, floors, ceilings),
- Install a new heating/air conditioning system,
- Change all carpentry (windows, doors),
- Totally reorganize space.
👉 Estimated budget: between 1,200 and 2,000 €/m2.
It is a significant investment, but it is also the one that gives real heritage value to the good.
2- Factors influencing the final price
The surface of the apartment
The area directly influences the overall cost. The larger the apartment, the higher the quote. However, the price per m2 may decrease slightly Some items of expenditure (installation of the site, relocation of craftsmen) are shared.
Initial housing status
Renovating an apartment that has not been maintained for 30 years has nothing to do with an already modernized housing. The older the apartment, the more the costs explode: re-establishing a standard electrical installation is expensive, and lead plumbing is often to be replaced in its entirety.
Selected materials
The choice of materials is one of the items where the budget can vary from simple to triple. Basic tile can cost 20 €/m2, while a quality ceramic stoneware reaches 80 to 100 €/m2. Same for paints: standard or ecological high-end, the difference is notable.
👉 It is advisable to find the right balance between quality, durability and aestheticsaccording to your priorities.
The location of the property
Labour and materials prices vary by region. In the provinces, rates are often more accessible than in Île-de-France or in some major coastal cities. In addition, the accessibility of the site (pedestrian city centre, high floor without elevator, complicated parking) can generate additional costs.
3. The largest expenditure items
The kitchen, a central and expensive space
The kitchen is often the heart of a renovation. Between furniture, home appliances and finishes, prices quickly fly away.
- Entry to the range: 3,000 to 8,000 €
- Midrange: 8,000 to 15,000 €
- Top of the range: 15,000 to 25,000 € and more
The bathroom, small room but big budget
It is one of the most expensive rooms to renovate because it concentrates plumbing, tile, furniture and sometimes floor heating.
- Simple renovation: 4,000 to 7,000 €
- Complete transformation: 8,000 to 15,000 €
Electricity and plumbing, invisible foundations
We don't see them very much, but these items represent a large part of the budget.
- Electrical upgrade: 80 to 150 €/m2
- Complete plumbing repair: 4,000 to 12,000 €
This work is essential to ensure safety and comfort.
Isolation and carpentry to reduce invoices
Renovating without improving insulation means missing substantial energy savings.
- Inner insulation: 40-90 €/m2
- Replacement of windows: 500 to 1200 € per unit
An investment that also improves the value of housing in the market.
4- Renovation and standards in 2025: what to know
New energy requirements
Since the gradual ban on "thermal passageways", energy renovation has become a must for landlords. A poorly classified apartment may lose value and be difficult to rent.
Financial support available
Fortunately, several devices allow the bill to be lightened:
- MaPrimeRenovation : up to 11 000 € According to work.
- Eco-loan at zero rate : interest-free financing.
- Energy saving certificates (EEC) Energy supplier premiums.
These aids are conditional on the intervention of RGE certified professionals.
The importance of a clear and detailed estimate
A good estimate must detail each item to clarify the costs of an apartment: labour, materials, deadlines, guarantees. This protects you from unforeseen events and allows you to objectively compare several companies.
5. How to optimize your renovation budget?
Setting priorities with methodology
It is crucial to distinguish the essential works (safety, conformity, energy) from aesthetic or comfort elements. This prioritization avoids exceeding the budget from the first steps.
Compare several quotes to better negotiate
Request at least 3 quotes gives you a fairer view of the market and allows you to negotiate. Please note: the cheapest quote is not always the best choice, check the quality of the materials offered and the company's reputation.
Choose a qualified professional
An experienced and certified RGE craftsman can not only guarantee quality work, but also open up access to financial assistance. It is an investment that secures your project and values your property in the long term.
✅ Conclusion: Anticipating for better investment
In 2025, the cost of an apartment renovation varies between 200 and 2000 €/m2 depending on the scale of the project. The main thing is to prepare its budget well, compare estimates and anticipate energy standards.
