What is RPI data?
The Retail Prices Index (RPI) is the most familiar general purpose domestic measure of inflation in the United Kingdom. It is available continuously from June 1947. The Government uses it for uprating of pensions, benefits and index-linked gilts. It is commonly used in private contracts for uprating of maintenance payments and housing rents. It is also used for wage bargaining.
