How to Read These Figures

  • Businesses are enterprises whose main activity is this industry, as counted by the ONS Annual Business Survey. A company with many sites counts once.
  • Turnover is the industry's total sales, including exports and excluding VAT, in cash terms. It is not adjusted for inflation, so part of any rise reflects higher prices.
  • 2019 is the starting point because it is the last year before the pandemic; 2020 would flatter most growth rates.
  • Every number links to the exact table and cell it comes from. Percentage changes and turnover per business are calculated directly from those cited figures.
