The 2017 International Trade in Services (ITIS) publication provides a detailed breakdown of annual trade in services estimates, analysing data by country, product and industry. These data are sourced from the International Trade in Services Survey.

The ITIS survey is the main source of UK services trade data, although it is important to note that the survey does not cover the whole of the UK services economy. The travel, transport and banking industries are not covered by the ITIS survey, as these data are obtained from other sources such as the International Passenger Survey and the Bank of England. Estimates for the overall level of trade in services, including these industries, are published in the annual Pink Book and monthly UK trade publications.
