In Q1 2026, production costs in construction rose by 1.4% over a quarter and by 2.1%
over a year Costs of production indices in construction - first quarter 2026
In Q1 2026, the production costs in construction rose by 1.4% over a quarter, after +0.1% in the Q4 2025. They rose in building construction (+1.2% after a stability), driven by a rebound in machinery for structural work costs (+0.7% after -1.3%) and in materials costs (+1.9% after -0.6%) and by a sharp acceleration in energy costs (+10.2% after +0.4%). Production costs bounced back in civil engineering (+1.5% after -0.4%): energy costs accelerated sharply (+17.7% after +0.9%) and machinery for public works costs bounced back (+0.4% after -0.6%), as did materials costs (+0.4% after -2.2%). They accelerated in specialised construction works (+1.4% after +0.3%), due to the acceleration in renovation materials costs (+1.9% after +0.1%) and to the rebound in specialised public works materials costs (+1.8% after -0.3%).
Year on year, the production costs in construction accelerated (+2.1% after +1.5% in Q4 2025). They accelerated in building construction (+2.0% after +1.5%), in civil engineering (+0.4% after +0.2%) and in specialised construction works (+2.6% after +1.9%).

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.
