Construction output rises 3.5% year-on-year, with new housing construction still a prominent reason for increases in output and materials price inflation


  • Construction output rose 1.8% month-on-month and 3.5% year-on-year in September 2014.
  • New housing construction continues to be the predominant reason for increases in new work output and materials price inflation
  • Construction materials prices rose by 1.0% in the year to September
  • Consumer price inflation increased to 1.3% in October, from 1.2% in September
  • Construction average weekly earnings increased on a yearly basis by 2.4% for total pay and 1.3% for regular pay (three-month averages) in September

The following chart shows Aecom’s index series since 2000, reflecting cost movements in different sectors of the construction industry and consumer prices.

Cost Update 2811

Building cost index
Building costs increased in the year to Q3 2014 by 2.2%. Wage awards effective in Q3 are the largest component of the increase.

Mechanical cost index
The rate of annual change was 0.5% at Q3 2014. Although this is an increase on Q2’s rate of annual change, it is explained by the base effects of the index in Q3 2013 which was lower than its preceding quarter last year.

Electrical cost index
The electrical cost index increased by 1.4% in Q3 2014. Again, this is due to a fall in the index between Q2 and Q3 last year, not significant increases in the present index level.

Consumer prices index
The annual consumer price inflation rate was 1.3% at October 2014. This was a small increase on September’s figure of 1.2%.


Price Adjustment Formulae indices, compiled by the Building Cost Information Service (previously by the Department for Business Innovation & Skills), are designed for the calculation of increased costs on fluctuating or variation of price contracts. They provide useful guidance on cost changes in various trades and industry sectors - i.e. those including labour, plant and materials - and on the differential movement of work sections in Spon’s Price Books.
The 60 building work categories recorded an average increase of 1.2% on a yearly basis.

Mechanical services materials for housing fell on an annual basis at -1.0%. The index of mechanical services materials for non-housing work continues to show little change. The electrical services materials index declined by 0.5% annually in September; however, this current rate of decline slowed from changes recorded throughout 2014.

UK economy

Cost update 7

The annual rate of consumer price inflation rose to 1.3% in October. This was a marginal increase on the figure posted in September, which was a five-year low at 1.2%.

Cost update 8


Input prices are falling at their fastest rate since September 2009. Input prices fell 8.4% annually at October, an increased rate from that in September when prices were falling at an annual rate of 7.4%. Core input inflation, which excludes volatile items, decreased 2.7% in the year to October. The price of oil is the largest component of the decline.

Cost update 9

Output prices of UK manufactured goods (factory gate prices) fell 0.5% in the year to October. This is the fourth consecutive fall in the index. The narrower core index, which excludes volatile items such as petroleum and food, increased 0.9% in the year to October.

Sterling fluctuated against the euro in the third quarter of 2014 but maintained its strength overall. The same was not true against the US dollar, where continuing dollar strength saw sterling fall by 7% over the quarter.


  • In September 2014, average weekly earnings (total pay including bonuses) in construction increased to £563 from £558 in August. Annually, earnings rose 2.4% in September, using a three-month average basis. Regular pay (excluding bonuses and arrears) increased at a slower yearly rate of 1.3% on a single month comparison.
  • Construction industry regular pay broadly tracked similar changes to average earnings for the whole economy. However, total pay statistics for the construction industry outstripped the same measures for the whole economy, at 2.4% and 1.0% respectively (three-month averages).
