Price of a fitted
window.

The prices below do not come from a national price list: we took 142 window lines from 25 of our quotes, drawn up between 2024 and 2026 for houses and flats in Savoie and Haute-Savoie. Each window there is supplied and fitted by our joiners, without shutter or blind; the removal of the old one is counted separately. French windows, sliding windows and roof windows are left aside: their price follows other rules.

We classed each window by its area, calculated from the dimensions written on the quote, then kept one price per quote and per size. The ranges run from the first to the ninth decile, rounded to €50: eight quotes out of ten fall within them. The median prices are €570 excl. VAT for a small window, €900 for a standard one and €1,100 for a large one. A roller shutter or sun-shading louvre built into the window is priced on top. The 5.5% rate assumes a window that reaches the performance thresholds detailed below.

Brought back to area, the ranking is reversed. In our quotes, the median price reaches about €1,230 excl. VAT per m² for a small window, €1,030 for a standard window and €620 for a large one. A bathroom window therefore costs, per square metre, twice as much as a living room window.

The explanation lies in everything that does not depend on size: the opening hardware, the fitting time, the sealing against air and water, the adjustment of the opening sashes. These items weigh as much on a small window as on a large one. That is why a per-m² price found online cannot be used to estimate a house: count your windows one by one, size by size.

When the material is specified on the quote line, it is PVC more than eight times out of ten. Our ranges are therefore most solid for PVC. For the other materials, our quotes for the period contain too few lines to publish an honest range, and we prefer to say so.

Aluminium. On the only quote where the same 95 × 60 cm window was priced in both materials, the aluminium version cost about 50% more than the PVC version. Its slimmer profiles leave more glazing for the same opening.

Timber. Only one timber window line appears in our recent quotes: a pine window with glazing bars, with burglar-resistant glazing. It came to about three times the price of a PVC window of the same size. One case does not make an average, but it gives the order of magnitude of made-to-measure timber joinery.

Timber-aluminium composite appears in none of our 2024-2026 quotes: we give no price.

The material is not chosen on budget alone. In an old town centre or near a monument, the regulations may impose timber or a specific design: this is the subject of our pages on window replacement in Annecy and in Aix-les-Bains.

The price of a "fitted" window also depends on what is taken out and how the new one is fixed. Four lines make the bill vary.

Removal of the old window. Our quotes count it separately, at €80 to €120 excl. VAT per unit removed and disposed of (seven quotes). When all the joinery in a house is changed, it often takes the form of an overall lump sum.

Fitting onto the old frame or full removal. Keeping the existing frame avoids touching the interior reveals and the plastering. Removing the whole frame means reworking them, an item we price separately depending on their condition. The choice has a lesser-known financial consequence: the CEE premium for windows is valid only if the old frame is replaced.

Surface-mounted fitting with frame extension. When the walls receive internal lining or external insulation, the window receives a frame extension, a piece that widens the frame to reach the new thickness of the wall: 140 or 160 mm on our quotes. These windows remain within the ranges in the table.

The window sill. When the concrete sill is damaged, it is redone: €250 excl. VAT per unit on the two quotes that price it.

When the glazing is specified, our 2024-2026 quotes provide double insulating glazing, with a stated Uw coefficient of 1.3. None includes triple glazing: we therefore have no price to publish for it.

Triple glazing is not automatically the right choice in the mountains. An extra pane reduces heat loss, but also lets in slightly less solar energy, which heats a south-facing living room for free in winter. Performance is therefore read on two values: the U coefficient, for losses, and the solar factor S, for gains. These are precisely the two values that determine reduced VAT and the CEE premium: check them on the technical data sheet before signing, especially for triple glazing.

On a north facade, in shade almost all day, the reasoning changes: solar gains there are low, and limiting losses comes first.

VAT at 5.5% applies to windows and French windows whose U coefficient does not exceed 1.3 W/m².K with a solar factor S of at least 0.3, or whose U coefficient does not exceed 1.7 with an S factor of at least 0.36 (article 30-0 D bis of Annex IV to the French general tax code, in force since 1^st January 2025). For a roof window, the threshold is U ≤ 1.5 and S ≤ 0.36. The home must have been completed more than two years ago; if the window does not reach the thresholds, the 10% rate for improvement works applies. The detail is in our guide to VAT on works.

MaPrimeRénov' no longer funds windows on their own: since 1^st September 2026, the per-measure scheme no longer covers insulation (order of 25 August 2026). Windows remain eligible in a whole-house renovation, reserved for homes rated E, F or G, with at least two insulation measures and a gain of at least two energy classes. Our MaPrimeRénov' 2026 page details the rates.

The CEE premium (sheet BAR-EN-104) targets the replacement of a single-glazed window, frame included, in a home more than two years old, with the same U and S thresholds as reduced VAT. Replacing a window that is already double-glazed does not qualify, and the premium requires a firm holding the quality mark required for this work.

The zero-interest eco-loan (éco-PTZ) remains available for a window replacement on its own, for up to €7,000 borrowed.

Our RGE CertiRénov certification (no. CR-2026-73-0095) covers the whole-house renovation offer: it comes fully into play when the windows are part of an overall insulation project.

To fix an order of magnitude, let us apply the median prices from our quotes to a house changing eight windows, with removal of the old ones:

This calculation is not a real project: it counts neither the reworking of the reveals, nor the sills, nor the shutters, which depend on each house. Above all it shows that a whole house is priced window by window.

Replacing windows with a different model, whether in material, colour or glazing bars, changes the external appearance and requires a prior declaration (déclaration préalable) at the town hall. Processing takes one month, two in a protected area. The planning rules of Savoie municipalities often set the colour of joinery: better to know before manufacture than after.

As windows are made to measure, we place the order once authorisation has been obtained. Our guide to the prior declaration details the file; in Chambéry, see also our page on window replacement in Chambéry.

The replacement of all the joinery, front doors, sliding windows and shutters included, is covered in our guide changing your joinery.
