Informations rapidesIn Q2 2026, production costs in construction rose by 2.6% over a quarter and by 4.7% over a year Costs of production indices in construction - second quarter 2026

In Q2 2026, the production costs in construction rose by 2.6% over a quarter, after +1.4% in the Q1 2026. They accelerated in building construction (+1.8% after +1.2%), in civil engineering (+6.1% after +1.5%) and in specialised construction works (+1.8% after +1.4%). This sharper increase was mainly driven by the acceleration in materials costs: +3.1% after +2.0% in building construction, +13.6% after +0.4% in civil engineering, +2.9% after +1.9% in renovation and +3.6% after +1.9% in specialised public works.

Year on year, the production costs in construction also accelerated (+4.7% after +2.1% in Q1 2026). They accelerated in building construction (+3.6% after +2.1%), in civil engineering (+7.3% after +0.4%) and in specialised construction works (+4.1% after +2.6%).

Production costs in public works

  • Source: INSEE.

Revision

For the first quarter of 2026, the quarterly and annual changes in the construction production cost index are unchanged: they stand at +1.4% and +2.1% respectively, as published in June 2026.

For further information

Monthly production cost indices are released every three months.

These indices aggregate the cost indices of six or seven factors of production: capital, labour, energy, materials, services, transport and wastes (only for public works). Please note that these indices are based on the production and import prices of inputs and measure costs before any subsidies or reimbursements.

These indices are subject to revision. They are primarily used as inputs for the national accounts and macroeconomics analyses.

Next issue: end of December 2026.
