Figure 4 - In 2025Q1 the decrease (-0.1) in RTI hours worked causes an increase (0.1) in RTI output per worker
Figure 5 - In 2025Q1 the decrease (-0.1) in RTI hours worked causes an increase (0.1) in RTI output per hour
Figure 6 - Small (less than 0.01) changes in contributions
Figure 7 - Corrections to hours growth and OPH growths to all sectors.
The error also causes small changes in the datasets Output per hour, Output per hour worked by division, Labour cost labour income and the time series PRDY and UCST released in the 14 August 2025 and 13 November 2025.

Notices
13 November 2025
We apologise for the delay in the update to our PRDY and UCST time series. This was caused by an error in the publishing process. The updated data are now ready to view.

Compensation of employees (CoE) by industry is estimated by applying whole‑economy year‑on‑year CoE growth rates to industry-level data for periods after the latest Supply and Use (SU) balanced year (currently 2023).
This approach results in limited variation in CoE growth across industries. This means that trends in Labour Costs and Labour Income for post‑SU balanced years may not fully reflect underlying differences between industries.

An error has been identified in data used to calculate unit wage costs for Section C (Manufacturing) in this time series dataset.
This error affects the following data:
data from Quarter 1 (Jan to Mar) 1982 to Quarter 4 (Oct to Dec) 1996 in CDID DIX4: Unit wage costs: Manufacturing C SIC07, 2023=100, seasonally adjusted, UK
data from Quarter 2 (Apr to June) 1982 and Quarter 1 1997 in CDID DJ4I: Unit wage costs: Manufacturing C SIC07, percentage change on quarter, seasonally adjusted, UK
data from Quarter 1 1983 to Quarter 4 1997 in CDID DJ4J: Unit wage costs: Manufacturing C SIC07, percentage change on year, seasonally adjusted, UK
This happened because of an outdated data series being used in the calculation of pre-1997 manufacturing unit wage costs. The error will be corrected and updated data will be published in our Productivity flash estimate and overview, UK release on 18 August 2026. No other industries or series are affected.
