Data within this bulletin

All data within this bulletin, unless specified, are presented in chained volume measure (CVM), otherwise known as real. This means the effect of price changes has been removed (in other words, the data are deflated).

In Quarter 3 (July to Sept) 2024, the Quarterly Acquisitions and Disposals of Capital Assets Survey (QCAS), the largest data source for gross fixed capital formation (GFCF) and business investment, had a response rate of 65.3% for estimates used in the provisional release.

Adjustments

Large capital expenditure tends to be reported later in the data collection period than smaller capital expenditure. This means that larger expenditures are often included in the revised results but are not reported in time for the provisional results. This can lead to a tendency toward upward revisions in the later estimates for business investment and gross fixed capital formation (GFCF).

Following investigation of the impact of this effect, from Quarter 3 2013, an approach to apply a bias adjustment was introduced in the provisional estimate. Any bias adjustment is later removed in the revised release.

This adjustment approach was suspended in Quarter 2 (Apr to June) 2020 because of uncertainties surrounding the effect of the coronavirus (COVID-19) pandemic. However, since Quarter 4 (Oct to Dec) 2021, after further investigation and analysis of its impact, the bias adjustment approach was reintroduced to business investment and GFCF. The bias adjustment for this provisional release is £1 billion.
