Users should exercise caution when comparing the Production in Building and Construction Index release with the New Dwelling Completions release due to timing and other comparability issues. For example, while the work completed by a firm on a residential building could take place over several months, the New Dwelling Completions will only count the building as completed when it has been connected to the ESB electricity network.
Please see the Background Notes in both the Production in Building and Construction Index release and the New Dwelling Completions release for further information on methodologies.
Users should note that the Production in Building and Construction Index will undergo a rebase adjustment later this year. An index rebase is a routine process conducted to recalculate weights and reform methodological procedures implemented. As a consequence of this process, data may be revised.
The volume of production in Building and Construction rose by 4.9% in Quarter 1 (Q1) 2025 when compared with Quarter 4 (Q4) 2024.

The headline table shows the seasonally adjusted volume and value indices for production in building and construction for Q1 2024, Q4 2024, and Q1 2025. It should be noted that the deflator, used in the calculation of the Production in Building and Construction Index (PBCI), has increased over the past 12 months and shows a 2.0% increase in Q1 2025 when compared with Q1 2024. See the Background Notes for more details. Further information on seasonal adjustment is available in the CSO's video on Seasonal Adjustment.
