Introduction

The Construction Output Statistics published in this bulletin and the accompanying tables provide a general measure of the quarterly and annual changes in the volume and value of construction output in Northern Ireland for Quarter 2 2026 (April to June).

Output estimates are calculated from the Quarterly Construction Enquiry (QCE) aspect of the Quarterly Business Survey (QBS). They exclude work carried out by Northern Ireland Construction firms in other parts of the UK or elsewhere. All figures are adjusted for seasonality where a seasonal variation has been found to exist.

Estimates of construction output are converted into indices which are a convenient way of expressing time series, making it easier to see changes in the series. Each series is expressed in relative terms, with the average turnover in 2023 set as the base value of 100. All other turnover values are then measured in relation to this base.

Key Points

  • In Quarter 2 2026 the total volume of construction output decreased by 1.7% over the quarter, increased by 3.5% over the year and increased by 3.6% on a rolling four quarters basis1.
  • In Quarter 2 2026, a quarterly decrease was seen in New Work (5.1%) while there was an increase in Repair & Maintenance (6.7%).
  • In Quarter 2 2026, there were decreases in the Housing (1.9%) and Other Work (0.5%) subsectors. However, the Infrastructure subsector increased by 6.3%, compared to the previous quarter.

1 Rolling four quarters compares the total for the latest four quarters with the total for the previous four quarters.
