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 held steady at 3.0% in October 2017, the same rate as in September. This is the CPI’s highest rate since April 2012.
The RPI inflation rate increased to 4.0% in October, up from 3.9% in September. This is the RPI’s highest rate since December 2011.
Within the CPI rate, the cost of transport fell, mainly due to a decrease in fuel costs, as did the price of furniture and household goods. However, this was offset by increases in the price of food and recreation and culture.
