UK Inflation History

UK inflation has varied dramatically over the decades. The 1970s saw peak inflation of over 24% (1975). The Bank of England was given independence in 1997 with a 2% inflation target, which kept inflation relatively stable until the 2022 energy crisis pushed it to 9.1%.

What is CPI?

The Consumer Price Index (CPI) measures the average change in prices of a basket of goods and services bought by UK households. It is the primary measure used by the Bank of England and the government to measure inflation.

How Inflation Erodes Purchasing Power

At 2% annual inflation (the Bank of England's target), money loses roughly half its purchasing power over 35 years. At 5% annual inflation, purchasing power halves in just 14 years. This is why investing and earning interest on savings matters.

UK Inflation Rate 2025

UK CPI inflation in 2025 is running at approximately 2.8%, having fallen significantly from the 2022 peak of 11.1%. The Bank of England base rate remains at elevated levels as the Monetary Policy Committee works to sustainably return inflation to the 2% target.
