Inflation: Data on both the CPI and RPI inflation indices.Jump to full report >>
The Consumer Prices Index (CPI) is the main measure of inflation. It is produced in line with international standards and is the measure used for the Bank of England’s 2% inflation target. The Retail Prices Index (RPI) is no longer classified as a National Statistic as the way it is calculated does not meet international standards. It is included here as it is well-known and is the longest running measure of inflation.
The CPI inflation rate was 1.0% in September, the highest since November 2014 when it was also 1.0%. The RPI inflation rate also increased from 1.8% in August to 2.0% in September.
The main contribution to the increase came through rising prices for clothing, overnight hotel stays and motor fuels, and prices for gas, which were unchanged, having fallen a year ago. These upward pressures were partially offset by a fall in air fares and food prices.
