Retail Inflation Data
ONS Retail Price Index (RPI)
The Retail Price Index (RPI) measures the average price change on the basis of the changed expenditure of maintaining the consumption pattern of households and the composition of the consumer population in the base or reference period. The coverage of goods and services is similar to the CPI, although the RPI includes council tax, mortgage interest payments, house depreciation, buildings insurance, ground rent and other house purchase costs such as estate agents’ and conveyancing fees, whereas the CPI does not.
