Gross domestic product (GDP) measures the value of goods and services produced in the UK. It estimates the size of and growth in the economy.


Next month we will be publishing our larger time series dataset on a separate entry in the release calendar to the bulletin and accompanying datasets. We have had to separate these for technical reasons. This dataset will appear in the release calendar as GDP monthly estimate, UK: March 2021 time series.



The United Kingdom Statistics Authority has designated these statistics as National Statistics, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Official Statistics.

Designation can be broadly interpreted to mean that the statistics:

  • meet identified user needs
  • are well explained and readily accessible
  • are produced according to sound methods
  • are managed impartially and objectively in the public interest

Once statistics have been designated as National Statistics it is a statutory requirement that the Code of Practice shall continue to be observed.

Changes to this release date

  • Previous date:
    12 April 2021 07:00
    Reason for change:
    As the end of the transition period for the UK leaving the EU approaches, the Office for National Statistics (ONS) recognises that this will change how data collection and processing is carried out for our trade data. We are working to ensure that our data reflects only changes in economic trends and not any changes in processing methods. Taking this into consideration, we have made the decision to make some small delays to some of our publications in 2021, ensuring that we have adequate time to quality assure our estimates. The February releases of UK trade, Monthly GDP, Quarterly GDP, Index of Production, Index of Services and Construction will now be published on 12 February 2021 rather than on the 10 February 2021 as originally planned. The April releases of UK trade, Monthly GDP, Index of Production, Index of Services and Construction will now be published on 13 April 2021 rather than on the 12 April 2021 as originally planned.
