Construction cost index, France

How much more renovation costs in France than it did in 2021, taken from the French statistics office. In Q1 2026 the index stood +19.9% above the 2021 average, and +1.7% above the same quarter a year earlier.

What this series measures

This one measures exactly what you are doing: Insee calls it the price index for the maintenance and improvement of buildings, residential, so it follows renovation work on existing homes rather than new build. That makes it a closer fit than the Spanish series on the sister page, which has to fall back on new housing. The figures are before VAT.

Latest published period: Q1 2026 (provisional; Insee can still revise it). Base 2021 = 100, prices before VAT.

The third column is the step between two neighbouring annual averages; it is not published as a figure in its own right. There is nothing for 2019, where the series starts here. Recent years carry quarters Insee can still revise, and the last year so far holds only the quarters published to date.

What it does not tell you

An index is not a price for your job. It measures an average movement across many building sites, across the whole of France and before VAT; your region, your house and the firm working on it may have moved differently. A converted amount is there to prepare a conversation, not to fix a price.

An index moves the ground under the prices; it does not price your job. For that, What the work costs per square metre in France has the ranges published for actual work, with the calculator underneath.

Frequently asked questions

Does this cover renovation, or new build?

Renovation. Insee publishes it as the price index for maintenance and improvement of residential buildings, which is work on homes that already exist. That is the one thing it does better than the Spanish series, where no renovation index is published at all.

Is the latest figure final?

Not always. Insee marks recent quarters as provisional and can revise them later. Where that is the case this page says so next to the figure rather than quietly presenting it as settled.

Does the index include TVA?

No, the series is before VAT. Which French rate applies to your work, and the three conditions attached to the lower ones, is a separate question that the page on TVA answers with the article next to each line.
