Construction costs: departmental reductions 2012-2013

This publication was published under the 2010 to 2015 Conservative and Liberal Democrat coalition government

Departmental construction cost benchmarking data, including benchmarks, predicted speed of cost reductions and cost reductions achieved.


The government has been publishing cost data since 2012 in order to understand the cost of government construction, to drive down costs and to deliver 15 to 20% savings by the end of this parliament. The latest December 2013 data shows that costs are continuing to go down, and it gives a level of comparison data which will assist a greater debate between industry and government as we work towards securing a sustainable low cost position. By publishing this data we will drive transparency, collaboration and challenge across public and private sector construction clients, with central government taking the lead.

The December addendum supplements the departmental construction cost benchmarks (£/m2, £/km, etc) originally published in July 2013. It also sets out the corresponding cost reduction trajectories (ie the speed with which cost reduction will be achieved) and the actual cost reductions achieved during 2012 to 2013.

Taken together this information shows the range of costs currently paid for departmental construction projects and the plans departments are developing to reduce those costs. It also provides further evidence that the overarching target of the Government Construction Strategy - to achieve a sustainable reduction in the cost of construction by 15 to 20% by the end of this parliament - remains practicable.
