Construction output is a measure of the activity of businesses in Great Britain (Northern Ireland conduct their own equivalent survey) that are classified to the Construction Industry. ‘Output’ differs from ‘turnover’ in that it is net of payments made to subcontractors and to suppliers of purchased services (architects, quantity surveyors, etc). By measuring ‘output’ double counting of activity within the construction industry is avoided. Construction contributes approximately 6.8% to the UK’s GDP.
This bulletin shows output in the construction industry for the fourth quarter of 2012. Most figures are estimates in constant (2005) prices, seasonally adjusted. The overall estimate for construction output this quarter was 0.9% higher when compared with the previous quarter and 9.3% lower when compared with the same quarter in 2011. Compared with the same quarter in 2011, there were falls in seven of the nine published sectors. Growths were seen only in private industrial and public housing repair and maintenance, but these are relatively small sectors (approximately 3% and 6% of total output respectively).
Further breakdowns, including non-seasonally adjusted and current price series, can be found in the

. This publication focuses on the latest quarterly figures, but also includes latest annual and monthly estimates as well as revisions to earlier periods in line with our revisions policy.
The preliminary estimate of quarter four 2012 Gross Domestic Product (GDP) included a nowcast of a rise of 0.3% in construction output in the fourth quarter of 2012 compared with the previous quarter.
The estimate released in this publication shows that construction output grew by 0.9% in the fourth quarter.
There is, therefore, no impact at one decimal place on the preliminary quarter four 2012 GDP estimate from this release of construction output estimates.
New work in the fourth quarter of 2012 grew by 1.6% compared with quarter three. The largest rises were in private housing (5.9%) and infrastructure (4.2%) partially offset by falls in public non-housing and private housing repair and maintenance (4.9% and 4.8% respectively).
Over the year from the fourth quarter of 2011 to the fourth quarter of 2012, there was a 9.3% fall in total construction output. The overall fall in new work was 11.6%. There were decreases in all types of new work other than private industrial, but this is a small sector. The largest falls in new work were seen in public non-housing (18.5%) and private commercial (17.0%). Repair and maintenance output fell by 4.7% over the same period. The only sector of repair and maintenance that grew in this period was public housing (3.4%).
The fourth quarter of 2012 sees the continuation of the decline in public new work sectors (public housing and public non-housing) which, as reported last quarter, have seen an almost continuous decline since the fourth quarter of 2010.

The volume of new private housing work in the fourth quarter of 2012 was 5.9% higher compared with the previous quarter but 3.8% lower than the same quarter in 2011.
The volume of new public housing work in the fourth quarter of 2012 was 1.9% cent lower compared with the previous quarter and 17.0% lower than the same quarter in 2011. There has been a downward trend in this sector since the fourth quarter of 2010.
During the last year private housing output volumes have been approximately three times bigger than public housing output volumes.
The volume of new infrastructure output in the fourth quarter of 2012 was 4.2% higher compared with the previous quarter. Compared with the same quarter a year ago infrastructure new work fell by 6.1%.
The volume of new work in the public non-housing (excluding infrastructure) in the fourth quarter of 2012 was 4.9% lower compared with the previous quarter and 18.5% lower compared with the same quarter in 2011. This sector has been declining since the fourth quarter of 2010.
The volume of new construction in the private industrial sector in the fourth quarter of 2012 grew by 2.5% compared with the previous quarter and was 5.4% higher than the same period in 2011.
The volume of new construction in the private commercial sector in the fourth quarter of 2012 grew by 1.0% compared with the previous quarter but was 17.0% lower than the same period in 2011.
The volume of housing repair and maintenance work (including improvement work) in the public sector in the fourth quarter of 2012 was 0.8% lower compared with the previous quarter but 3.4% higher than the same quarter in 2011. This sector has been broadly flat from the beginning of 2011.
The volume of housing repair and maintenance work (including improvement work) in the private sector in the fourth quarter of 2012 was 4.8% lower compared with the previous quarter and 14.3% lower compared with the same quarter in 2011. The quarter-on-quarter decline continues the trend seen in recent quarters.
The volume of repair and maintenance in the non-housing sector in the fourth quarter of 2012 was 2.3% higher compared with the previous quarter and 1.8% lower compared with the same quarter in 2011. The introduction of an infrastructure repair and maintenance question in 2010 means that we do not yet have sufficient data to produce seasonally adjusted estimates for the components of this series.
In general revisions will follow the standard revisions policy for construction statistics shown in the table below.
|Source of revisions||Revision periods|
|New survey data||New month + revised 12 previous months|
|Revised deflators from BIS*||New quarter + revised 2 previous quarters|
|Seasonal factors||New quarter + revised 5 previous quarters|
Revisions to the output series for the last 12 months were also due to revised and late responses from respondents.

Changes to Construction Statistics
In June 2009 ONS announced major changes to the arrangements for producing construction statistics and indicated that the changes would take effect from the beginning of 2010. From January 2010, a new Monthly Business Survey replaced the quarterly output surveys for construction, and a quarterly new orders survey replaced the previous monthly new orders survey.
Deflation and seasonal adjustment
'Value' of construction output is also known as 'current price' or 'nominal price' construction output. 'Volume' of construction output is also known as 'constant price' construction output. A volume series aims to measure the level of construction output, adjusting for price inflation, allowing comparisons of activity to be made between periods. The headline data are given in constant 2005 prices, seasonally adjusted. Deflators adjust the value series to take out the effect of price changes to give the volume series. Deflation of output is carried out sectorally, and a range of relevant tender price and output price indices are used.
Seasonally adjusted monthly estimates will not be available until enough monthly data are available for this to be done reliably. After 3 years of estimates are available, ONS will review if it is feasible to introduce a seasonally adjusted series.
