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) 2025, 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 66.8% 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 (Month 3) results but are not reported in time for the provisional (Month 2) results. This can result in upward revisions in the later estimates for business investment and GFCF. Following investigation of the impact of this effect, from Quarter 3 (July to Sept) 2013, an option to include a bias adjustment was introduced in the provisional estimate to help manage uncertainty around these early estimates. The bias adjustment for this provisional release is £1.6 billion.
