There are no revisions to previously published data in this monthly release because of the regular National Accounts revision policy. We will see data revisions from our pre-announced changes highlighted in the Impact of Blue Book 2023 article in the Quarterly national accounts release (to be published on 29 September 2023), and also in the next monthly GDP release (to be published on 12 October 2023).

1. Main points

  • Monthly production output is estimated to have fallen 0.7% in July 2023; this follows an unrevised growth of 1.8% in June 2023.

  • The monthly decrease in output in July 2023 resulted from a decline in three of the four production sectors, with manufacturing being the main contributor to the monthly fall (0.8%) with other smaller contributing decreases in electricity and gas (1.5%) and water supply and sewerage (0.5%); this was partially offset by a rise in mining and quarrying (1.9%).   

  • Monthly manufacturing output decreased by 0.8% and saw decreases in 9 of its 13 subsectors during July 2023; most notably, manufacture of rubber and plastic products and manufacture of computer, electronic and optical products fell 5.5% and 3.2%, respectively.

  • Looking at the longer-term profile, production output for the three months to July 2023 rose by 0.6% compared with the three months to April 2023; growth came solely from manufacturing (1.7%), partially offset by falls in electricity and gas (2.0%), mining and quarrying (3.2%) and water supply and sewerage (1.7%).

  • Further analysis of the effect on our monthly IoP estimate is available in our Gross domestic product (GDP) monthly estimate, UK: July 2023 bulletin, published 13 September 2023.

3. Measuring the data 

The Index of Production (IoP) uses data from a variety of sources. It is calculated by taking turnover and removing the impact of price changes, or by using direct volume estimates.

Most of these data are collected as "turnover values" through the Monthly Business Survey (MBS). In addition, direct volume series are collected by the Department for Energy Security and Net Zero (DESNZ), and the International Steel Statistics Bureau (ISSB) for steel industries.

The Office for National Statistics' (ONS) Monthly Business Survey (MBS) is fully online. Business owners can log on from any location and submit their data at an appropriate time. Most other data in the IoP come from the DESNZ, and therefore will be less affected than the survey data.

From January 2018, Value Added Tax (VAT) data have also been included across 64 production industries for small- and medium-sized businesses. For more information, see our VAT turnover data in National Accounts: background and methodology article. A comprehensive list of the IoP source data can be found in our Gross domestic product (GDP) data sources catalogue dataset

More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in our UK Index of Production Quality and Methodology Information (QMI).

Additional bank holiday in May 2023 for the Coronation of King Charles III

There was an additional bank holiday for the coronation of King Charles III on Monday 8 May 2023. While adjustments are made for regular calendar effects, there was no explicit adjustment for this ad hoc event. However, the timing of the bank holiday indirectly affects the number of trading days, which could affect GDP estimates positively or negatively, depending on the sector. This should be taken into account when interpreting monthly, and three-monthly movements over recent months since May 2023.

Revisions to IoP

In line with the National Accounts revision policy, this release gives data for July 2023 for the first time with no other periods open for revision.

The next monthly IoP release will be published on 12 October 2023, and we are open for revisions for all periods. These revisions will be consistent with the quarterly national accounts release that will be published on 29 September 2023, and they will incorporate improved source data, updated seasonal adjustment parameters, and additional updated data, as would happen in all quarterly national accounts releases. This includes new Value Added Tax (VAT) turnover data for Quarter 4 (Oct to Dec) 2022 and Quarter 1 (Jan to Mar) 2023.

Office for Statistics Regulation (OSR) review of GDP

The OSR will shortly be completing a review of the practices around the preparation and release of information about revisions to estimates of GDP in our Impact of Blue Book 2023 article released on 1 September 2023. This will cover the processes and quality assurance in making revisions to GDP and the potential improvements to early estimates of GDP enabled through enhanced access to data. It will also cover the communication of:

  • revisions to GDP

  • the story behind the most recent set of revisions in particular

  • uncertainty in early estimates of GDP
