Index of Production, UK: June 2023

• Monthly production output is estimated to have risen 1.8% in June 2023, the strongest monthly growth to the Index of Production (IoP) since August 2020 (1.9%); this follows an unrevised fall of 0.6% in May 2023.

• The monthly increase in IoP output in June 2023 resulted from a rise in two of the four production sectors, with manufacturing being the main positive contributor (1.7 percentage points), with a smaller contribution from water supply and sewerage (0.2 percentage points); electricity and gas remain unchanged on the month, with growth partially offset by a small contribution from mining and quarrying, which negatively contributed 0.1 percentage points.

• There was no explicit adjustment for the additional bank holiday held for the coronation of King Charles III on 8 May 2023 because this was an adhoc event (non-regular calendar effect); the timing of the bank holiday affects the number of trading days in May 2023, which users should consider when interpreting data on monthly movements in the IoP between May and June 2023.

• Monthly manufacturing output increased by 2.4%, the strongest monthly rise since November 2020 (2.5%), and saw 11 of its 13 sub-sectors positively contributing to growth during June 2023; most notably, the manufacture of basic pharmaceutical products and manufacture of transport equipment contributed 0.48 and 0.45 percentage points, respectively to the IoP June 2023 monthly growth.

• Monthly production output was 1.7% above February 2020, the last month of "normal" trading conditions before the coronavirus (COVID-19) pandemic; manufacturing and water supply and sewerage were above their February 2020 levels, by 3.9% and 8.9%, respectively, electricity and gas remained unchanged, and mining and quarrying was 24.6% below its February 2020 level.

• Looking at the longer-term profile, production output growth for Quarter 2 (Apr to June) 2023 rose by 0.7% compared with Quarter 1 (Jan to Mar), showing the strongest quarterly growth since Quarter 4 (Oct to Dec) 2020 (4.1%); growth came primarily from manufacturing, which contributed 1.2 percentage points to the IoP Quarter 2 2023 quarterly growth.

• Further analysis of the effect on our monthly IoP estimate is available in our Gross domestic product (GDP) monthly estimate, UK: June 2023 bulletin, published 11 August 2023.

All data related to the IoP are available on our Related data page. 

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 (XLS, 1.9MB).

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).

Revisions to IoP

In line with the National Accounts revision policy, this release gives data for June 2023 for the first time, with May and April 2023 also open for revision.
