Materials cost inflation continues to rise, although the effects of sterling’s weakness are filtering out slightly and the increase in input costs has slowed. Michael Hubbard of Aecom reports

ºÃÉ«ÏÈÉúTV cost index
A composite measure of building costs increased over the past 12 months by 3.9% at Q2 2017. Materials cost inflation continues to increase, as do labour rates. Inflation arising from higher imported materials costs still plays a part in the reasoning, but the effect of sterling weakness is working its way through and out of the system for the time being. This may well increase once again, as the pound has fallen against the euro recently. 

Mechanical cost index
The rate of annual change increased to 3.9% at Q2 2017. Both labour and materials components of the index increased, with the latter almost reaching 6% over the period. 

Electrical cost index
The electrical cost index increased by 2.5% over the year. The materials component of the index recorded a 5% change in the 12 months to Q2 2017. 

Consumer prices index
Consumer price inflation maintained a steady rate through the second quarter of 2017. The largest fall was recorded in motor fuel, but this was offset by increases in a range of other domestic goods and services.  

The following chart shows Aecom’s index series since 2005, reflecting cost movements in different sectors of the construction industry and consumer prices.

02 / Price adjustment formulae for construction contracts

Price adjustment formulae indices, compiled by the ºÃÉ«ÏÈÉúTV Cost Information Service (previously by the Department for Business, Innovation and Skills), are designed to calculate increased costs on fluctuating or variation of price contracts. They provide guidance on cost changes in various trades and industry sectors – ie 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 1.6% on a yearly basis. Higher increases were recorded in the following categories:

Consumer prices% change: July 2016 – July 2017
Consumer Prices Index (CPI) 2.6 â–²

Consumer price inflation rose by 2.6% in the 12 months to July. Consumer price inflation remains higher than overall earnings growth, contributing to falling real wage levels and a squeeze on consumer spending. With increased raw materials costs now passed into the supply chain and out to consumer prices, recent falls in the value of sterling will be watched for renewed effects on input cost inflation. 

 

Industry input costs% changeJuly 2016 – July 2017
Materials and fuels purchased by manufacturing industry 6.5 â–²
Materials and fuels purchased by manufacturing industry excluding food, beverages, tobacco and petroleum industries 5.5 â–²

Input costs increased by 6.5% on a yearly basis to July 2017 – a notable slowing in the annual rate of change when compared with change in the preceding months of 2017, decreasing by 13.4% from a peak of 19.9% in January. Further consolation is found in the July figure as it records the slowest rate of annual change since July 2016 at 4.2%, while the monthly movement of 3.5% from June 2017 is the largest downward shift since April 2012. Moderate strengthening of sterling and a fall in crude oil by about 12% over H1 2017 are two reasons there is a slower rate of inflation for materials and fuels inputs.  

 

Industry output costs% changeJuly 2016 – July 2017
Output prices of manufactured products 3.2 â–²
Output prices of manufactured products excluding food, beverages, tobacco and petroleum 2.4 â–²

Source: ONS

Factory gate prices increased 3.2% on a yearly basis in July. Falling input costs in recent months have contributed in part to a slower rate of overall output price growth. As recent large rises in input costs have eased a little, output prices have continued to increase steadily, offering some respite for producers in managing the balance between input cost pressure and output prices. However, the rate of change in output price inflation has slowed through 2017.

Commodity prices mainly continued to make gains through the second quarter of 2017. This follows downward drift in prices through the preceding quarter. Prices are therefore at similar levels to those seen at the turn of the year. Global economic growth expectations are perceived to be improving, with corresponding knock-on effects on demand for metals commodities.

GBP / USD 1.3141 1.2994 -1.1

Having followed broadly similar trends against the euro and the US dollar, sterling again lost ground against the euro during Q2 2017. It sank further more recently as eurozone economic confidence and performance beat the UK’s economic story,

and the situation is not helped by ongoing Brexit uncertainty weighing on the outlook. Against the US dollar, sterling’s performance is better, but this reflects changing views about the US economic landscape and political developments.

Labour

05 / Labour market statistics

  • Average weekly earnings (total pay including bonuses) in construction increased to £586 in June 2017, from £581 a month earlier.

Regular pay (excluding bonuses and arrears) rose to £564 per week in June, with annual rates of 2.4% on a single-month basis and 1.9% using a three-month average.
  • Construction industry regular and total pay rates of change are broadly in line with equivalent changes to average earnings for the whole economy classification.
  • Real average weekly earnings for the whole economy fell by 0.4% (regular pay) in June 2017 when compared with June 2016.

ºÃÉ«ÏÈÉúTV and Allied Trades Joint Industry Council

As the second part of a two-year agreement reached in 2016, this year will see a further 2.5% pay rise in all wage rates. Changes to employer pension contribution mean the minimum employer contribution prior to 5 April 2017 under pension auto-enrolment rules is 1% of pensionable pay between £5,824 and £42,385. From 6 April 2017 until 5 April 2019 this minimum employer contribution will rise to 2%. From 6 April 2019 onwards it will rise to 3%.

Guide to data

Aecom’s cost indices track movements in the input costs of construction work in various sectors, incorporating national wage agreements and changes in materials prices as measured by government index series.

They are intended to provide an underlying indication of price changes and differential movements in the various work sectors but do not reflect changes in market conditions affecting profit and overheads provisions, site wage rates, bonuses or materials’ price discounts/premiums. Market conditions and commentary are outlined in Aecom’s quarterly Market Forecast (last published August 2017).
