2. Things you need to know about this release

The Construction Output Price Index is designated as a National Statistic, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Statistics.

Since taking responsibility for the Construction Price and Cost Indices (CPCIs) on 1 April 2015, we have developed the Construction Output Price Indices (OPIs). The indices use our existing data sources, all of which are National Statistics, so that users can be assured of the quality of the source data.

Improvements to the OPIs were made in September 2017 and have been published in the article Construction development: impact of improvements to construction statistics.

Prior to the Quarter 3 (July to Sept) 2017 release, the OPIs were calculated on a base year of 2010 (2010 equals 100). As of the Quarter 3 2017 release, the base year has been updated to 2015 (2015 equals 100).

In addition, there were further improvements implemented in the Quarter 3 2017 release. Further details can be found in Section 5 of the Construction development article released on 29 September 2017.

Revisions are subject to the revisions policies of component series; for routine revisions the series will remain open for a period of five months, in line with the Producer Price Index (PPI), its main component.

The OPI will also be revised on an annual basis to account for the profit mark-up margin update, introduced as part of the methodological improvements in the July to September 2017 release. It would be expected that these changes would take effect in the April to June publication each year, although this may depend on the availability of the data. Alternative sources for profit mark-up data are currently being investigated as a future possibility to improve the timeframe and provide data continuity.

Due to the improvements made to the Construction Output Price Indices publication in Quarter 3 (July to Sept) 2017, this publication is now a statistical bulletin. Previous releases prior to this were published as articles.

3. All construction price inflation summary

Overall, prices in the construction industry, as estimated by the Construction Output Price Index (OPI), rose 11.6% between October 2014 and June 2019 (Figure 1). Peaks and troughs seen within the new work index between October 2014 and June 2019 are mostly due to movements within the earnings component of the OPI, which is sourced from the Average Weekly Earnings (AWE) index for construction.

The annual rate of inflation for all construction was 3.0% in June 2019 (Table 1), up from 2.9% in May 2019. Annual growth for new work was 3.6% in June 2019, while annual growth for repair and maintenance was 1.6% in June 2019. Annual growth rates for the three main construction OPIs have remained positive since September 2015 (Figure 2).

The Construction Output Price Index (OPI) for new construction work rose 3.6% on the year and 0.4% on the month to June 2019 (Table 2). The annual rate of inflation for new work rose 0.1 percentage points from 3.5% in May 2019. Infrastructure showed the largest annual and monthly growth at 5.0% and 1.0% respectively.

Housing provided the largest upward contribution to the 12-month rate in June 2019 at 0.97 percentage points. The largest contribution to the monthly rate for new work came from infrastructure at 0.24 percentage points (Figure 3).

All sectors within new work provided upward contributions to both the 12-month and 1-month rate.
