Price of an
installed gate.

Catalogue prices often cover the gate alone, delivered without installation. On a project, the "gate" line is only one of the four lines that make an entrance: the gate and its finishing post, the motorisation, the masonry that receives it (post, pillar, threshold) and the electrical supply to the motor. Comparing two offers without checking what each puts in its line is comparing a leaf with a finished entrance.

Our figures come from five projects priced in 2025 and 2026, around Aix-les-Bains and Chambéry. That is few, and we prefer to say so: five real quotes are worth more than a national average, but they give an order of magnitude, not a price list. The price of your entrance depends on its width, the model chosen and the condition of the existing posts.

All our lines are gates supplied and installed, made to measure in powder-coated aluminium. For a complete entrance — a motorised sliding gate of 2.5 m by 2 m, matching wicket gate, reworking of the post and concrete threshold, motor cabling — one of our 2025 quotes totalled just under €9,700 excl. VAT.

The fence that extends the gate, its low walls and its panels have their own guide: the price of a fence. On land that retains earth, the low wall becomes a retaining structure, which is calculated differently: see our guide to the retaining wall.

All the gates priced in our recent quotes are sliding gates. We therefore have no price for a swing gate to give you, and we will not invent one.

The choice depends first on the terrain. A swing gate sweeps the ground in front of it as it opens: on a sloping entrance, as found on many of the hillsides around Lac du Bourget and Lac d'Annecy, its leaves may hit the rise. A sliding gate glides along the fence: it needs lateral clearance at least equal to the width of the opening, and a well-levelled concrete threshold for its rail. It is this threshold that the "reworking of the entrance" line of our quotes prices.

In winter, a rail in the ground must be cleared after a snowfall. On a shaded entrance or at altitude, this is a point to weigh before choosing.

The width. This is the first difference in our quotes: €4,200 to €5,800 excl. VAT for a 2.5 to 2.8 m opening, €7,600 to €9,200 excl. VAT for a 3.5 m gate.

The infill. Open bars, spaced slats or solid slats: the more solid the leaf, the more it weighs and the more it costs. The highest quote in our survey combines both factors, 3.5 m wide and solid slats.

The condition of the entrance. A concrete post to demolish and a threshold to pour represent €1,100 to €1,500 excl. VAT in our quotes; a new masonry pillar, reinforced and capped, €3,200 excl. VAT. When the entrance has to be widened, with demolition of the pillar and part of the low wall, we priced the whole for a lump sum: €8,820 excl. VAT for a 4.5 m opening, gate included.

The accessories. A video entry phone that opens the gate and the wicket gate from the house costs around €1,300 excl. VAT installed; an electric strike on the wicket gate is added to the price of the wicket gate.

In our quotes, the motor has no line of its own: it is included in the price of the sliding gate when the quote details it. The priced kit includes the motor and its control unit, the rack and its cover, two remote controls, a set of photoelectric cells, an amber warning light with its aerial and a backup battery.

Alongside the gate, an electrical line of €250 excl. VAT brings power to the motor, the cell and the intercom: 40 mm conduit, cable, junction box and reinforced socket. If the entrance is far from the house, the trench that receives the conduit is added, priced according to the distance.

Our masons prepare the post and threshold, our joiners install the gate, our electricians run the line: each in his own specialty, all salaried staff of the workshop and under the same contract.

Outside protected areas, a fence — and the gate it carries — in principle requires no planning formalities (article R*421-2 of the planning code). Article R*421-12, however, requires a prior declaration (déclaration préalable) in four cases: a remarkable heritage site or the surroundings of a historic monument; a listed or classified site; an area protected by the local plan (PLU) under its heritage and landscape articles; a commune that has decided to make fences subject to declaration.

In our areas, the question often arises. Between Lac du Bourget, a listed site since 1974, and the protected surroundings of the thermal baths, a gate may fall under a procedure in Aix-les-Bains; in the old centre of Chambéry, a remarkable heritage site, the declaration is required. Our pages on outdoor landscaping in Aix-les-Bains, Chambéry and Annecy detail these situations.

Processing takes one month, two months in a protected area, where the ABF heritage architect gives an opinion. To install in spring, the file must therefore be submitted in winter: our guide to the prior declaration describes the documents to provide.

If the entrance widens onto a pavement, lowering the kerb, the "dropped kerb" (bateau), is a separate application: a road occupancy permit (permission de voirie), requested from the town hall for a road within a built-up area (from the intercommunal authority in some towns).

VAT at 10% applies to improvement and maintenance work on a dwelling completed more than two years ago, usual outbuildings included. The tax doctrine in force (BOFiP published on 9 September 2026) lists among these outbuildings cellars, attics, garages, loggias and terraces, but not the gate.

As a precaution, the amounts including VAT in this guide are therefore calculated at 20%. The rate applied to your project appears on the quote, after examination of your home and the nature of the work. The general rules are detailed in our guide to VAT on building work.
