Index of Services, UK: June 2025

• Monthly services output was estimated to have grown by 0.3% in June 2025; this follows an increase of 0.1% in May 2025 and a fall of 0.2% in April 2025.

• There were monthly increases in 7 of the 14 sectors in June 2025; the largest positive contributions came from “professional, scientific and technical activities” (up 1.7%) and “wholesale and retail trade” (up 0.8%).

• The monthly increase in output in June 2025 was partially offset by monthly decreases in 5 of the 14 sectors in June 2025 (two sectors saw flat growth); the largest negative contributions came from “education” (down 0.5%) and “other service activities” (down 1.6%).

• Services output growth in Quarter 2 (Apr to June) 2025 was estimated to have increased (up 0.4%), compared with Quarter 1 (Jan to Mar) 2025.

• 7 of the 14 sectors showed growth in Quarter 2 2025; the main positive contributing sectors were “information and communication” (up 2.0%) and “human health and social work activities” (up 1.1%).

• Below section level, the “computer programming, consulting and related activities” (up 4.1%) and “human health activities” (up 1.9%) industries mainly contributed to the quarterly rise in Quarter 2 2025; this was partially offset by a fall in “wholesale” (down 2.4%).

Response rates for June 2025

The response rates for June 2025 were 75.2% based on forms returned. This accounted for 88.8% of total turnover coverage of the sample population. For further information, see our Current and historical Monthly Business Survey (MBS) (services) response rates dataset.

Data sources and collection

The Index of Services (IoS) is compiled using data from several different sources (share of overall economy based on latest gross value added (GVA) weights). These include the:

• Office for National Statistics (ONS) MBS (34.9%)    
• ONS Retail Sales Inquiry (4.8%)    
• ONS Government Expenditure (15.3%)    
• ONS Households’ Expenditure (11.2%)    
• ONS Finance Expenditure (8.0%)    
• ONS Households and non-profit institutions serving households (1.9%)
• other (3.6%)

The MBS data are published alongside this release in our MBS turnover of services industries dataset.

Data relating to the retail industry are broadly comparable with our Retail sales, Great Britain: June 2025 bulletin, published on 25 July 2025.

For further information on what is included within “other”, please see our Gross domestic product (GDP(o)) data sources catalogue.

The percentage of each data source is based on their gross value added weight. Our IoS methods and sources pages provide more information on the data that underpin these statistics; of particular note is our GDP(o) data sources catalogue.

Value Added Tax (VAT) data are also included for small and medium-sized businesses to help inform estimates. For more information, see our VAT turnover data in National Accounts: background and methodology.

Quality and methodology

The data reported in IoS bulletins and datasets are estimates that are subject to uncertainty, for example, sampling variability and non-sampling error. For more information on these, see Section 2 of our Uncertainty and how we measure it for our surveys methodology.

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

Accredited official statistics

These accredited official statistics were independently reviewed by the Office for Statistics Regulation in April 2014. They comply with the standards of trustworthiness, quality and value in the Code of Practice for Statistics and should be labelled “accredited official statistics”.

Revisions to Index of Services

In line with the National Accounts Revision Policy, this release gives data for June 2025 for the first time, with April and May 2025 open for revision.

Pausing of Producer Prices publications

Business prices data with corrected chain linking methods have been used in the Index of Services (IoS) dataset for producer price indices (PPI), import prices indices (IPI) and export price indices (EPI) from January 2025 onwards.

Correctly chain-linked service producer price indices have also been included in our IoS dataset from April 2025 onwards. The quarterly services producer price indices (SPPI) estimates are splined to months for use in monthly IoS calculations.

The full implementation of updated business prices data will be managed in line with the National Accounts Revision Policy. The full time series update will be included in our GDP quarterly national accounts, UK: April to June 2025 release, publishing on 30 September 2025, and our Blue Book 2025 publication.

Further information on the chain linking error in the producer prices dataset was published on 10 July 2025 in our Growth rates of selected output and input PPI and SPPI article.

Seasonal adjustment

The monthly estimates of IoS are seasonally adjusted. Seasonal adjustment is the process of removing the variations associated with the time of year, or the arrangement of the calendar, from a data time series.

IoS estimates, as for many data time series, are difficult to analyse using raw data because seasonal effects dominate short-term movements. Identifying and removing the seasonal component leaves the trend and irregular components.

The ONS uses the X-13-ARIMA-SEATS approach to seasonal adjustment. Seasonal adjustment parameters are monitored closely and regularly reviewed. For more information, please see our seasonal adjustment methodology page.

In our IoS estimates seasonal adjustment is applied at the industry level and the seasonally adjusted series are aggregated to create estimates by sector and total IoS output. As part of our quality assurance approach, residual seasonality checks are regularly completed by our time series analysis team on both the directly seasonally adjusted series and also the indirectly derived aggregate time series.

This topic is explored further in our Assessing residual seasonality in published outputs article published 09 May 2025.
