The next UK Consumer Price Index (CPI) bulletin is scheduled for publish on Wednesday, 22 October 2025, at 07:00 UTC. This release will cover September 2025 inflation data.
What is the CPI?
Published monthly by the Office for National Statistics (ONS), The UK CPI statisical bulletin is a monthly report that provides detailed data and analysis on inflation in the United Kingdom.
The bulletin focuses on the Consumer Prices Index (CPI), which measures the average change in prices over time that consumers pay for a typical basket of goods and services. It is one of the UK’s primary indicators for tracking inflation.
The release of CPI data is especially important because it helps guide Bank of England (BoE) decisions on interest rates and monetary policy. It is also used by government departments to adjust welfare benefits and pensions, by businesses to track input costs, and by investors to assess economic risks. In short, the CPI bulletin is a vital snapshot of inflationary pressures in the UK economy.
