Inflation has always been with us. Despite the erosion of savers wealth the Government is pretty tolerant of inflation rates in single figures. After all, it transfers wealth form savers to borrowers and the UK like most governments is a huge borrower.
There are several official measures of inflation, the most common of which are CPI and RPI. This site adds a third: MyPI based on an unscientifically selected basket of goods and services purchased by a retired person in Hertfordshire. A common perception is that the official figures are 'fiddled', so it is interesting to see how the three measures compare.
