Annual Inquiry of Construction and Allied Trades
The Annual Inquiry of Construction and Allied Trades is a survey of businesses within the construction and allied trades sector in Great Britain. The survey collects information about the nature of business, manpower and, for main contractors, the total value of new work carried out during the year.
The resulting information is used to maintain ONS’s register of businesses, ensuring an accurate and up-to-date sampling frame for other ONS construction surveys.
