This annual publication brings together a range of statistics currently available on the construction industry from the Office for National Statistics (ONS).

The construction industry is categorised as section F of the Companies House UK Standard Industrial Classification (SIC) 2007, which is defined as:

All data published are in current prices and, unless otherwise stated, non-seasonally adjusted and correct at the time of release, however, are subject to revisions as per the respective revisions policies.

Data relating to the numbers of construction firms and employees are point-in-time estimates classified in the third quarter of 2025 (July to Sept) on the IDBR. We use the same point in time each year to ensure consistency.

Construction output estimates

Construction output estimates are monthly estimates of the amount of output chargeable to customers for building and civil engineering work done in the relevant period, excluding Value Added Tax (VAT) and payments to subcontractors.

Construction Output Price Indices (OPIs)

The construction OPIs are compiled using input costs; material, labour and plant, which are weighted together for a selection of types of construction projects. A mark-up is then applied to account for profit by the construction firm. The result is considered a proxy for output prices.

Inter-Departmental Business Register

The Inter-Departmental Business Register (IDBR) is a comprehensive list of UK businesses registered for Value Added Tax (VAT) and Pay As You Earn (PAYE) used by government for statistical purposes. The IDBR provides the main sampling frame for surveys of businesses carried out by the Office for National Statistics (ONS) and other government departments. It is also an important data source for analysis of business activities.

The two main sources of input are VAT and PAYE records from HM Revenue and Customs (HMRC). Additional information comes from Companies House, Dun and Bradstreet and the ONS business surveys.

New orders

The new orders data measure the value and volume of new orders of main contractors by type of work and region.

Seasonally adjusted estimates

Seasonally adjusted estimates are derived by estimating and removing calendar effects (for example, leap years such as 2024) and seasonal effects (for example, decreased activity at Christmas because of site shutdowns) from the non-seasonally adjusted estimates.

Value estimates

The value estimates reflect the total value of work that businesses have completed over a reference month. Value estimates are also referred to as the data in current prices.

Volume estimates

The volume estimates are calculated by taking the value estimates and adjusting to remove the impact of price changes. Where chain-linking is applied, volume estimates are referred to as chained volume measures.
