Latest movement in the private housing construction price index

The BCIS Private Housing Construction Price Index is a measure of the prices paid by housebuilders for constructing houses/flats, i.e. changes in the costs of direct/subcontracted labour, plant and materials, overheads and profit attributed to the construction, but excluding the cost of land and other development costs and any development profit.

A range of small, medium and national housebuilders are surveyed each quarter to identify the change in prices paid for constructing a standard house type. Contributors are also asked to provide their expectations for price changes in the following quarter and the mean of these projections is published as a forecast for the current period.

Continued growth in housebuilding cost inflation

Annual housebuilding cost inflation, as measured by the BCIS Private Housing Construction Price Index (PHCPI), stood at 1.7% in 4Q2024, down from a peak of 15.3% in 2Q2022.

On a quarterly basis, this represented a 0.3% increase compared with 3Q2024.

At the same time, ONS construction output figures demonstrate reduced pressure on the private housing sector. In 4Q2024, private new housing output saw a quarterly increase of 1.3% and the sector was up by 3.8% on the same quarter a year earlier.

Karl Horton, BCIS Chief Data Officer, said: ‘In light of the government targeting 1.5 million new homes over the course of this Parliament, we’re also asking housebuilders about the current and expected impacts on their operations.

‘More commonly, respondents said their plans are aligned with internal expectations rather than government targets. They cautioned that labour shortages, planning constraints and supply chain issues could all serve as limiting factors.’

Of the respondents reporting a change in costs in 4Q2024, 40% reported an increase in materials’ costs, 20% pointed to an increase in labour costs, and 20% indicated an increase in sub-contractor costs. A further 20% said they had experienced a decrease in labour costs.

Looking to 1Q2025, the housebuilders surveyed said they expected to see an average increase in costs of 0.7% on the quarter.

We would like to thank the PHCPI survey respondents for their contribution.
