Understanding Inflation in the UK

What Is Inflation?

Inflation is the general increase in prices over time, which reduces the purchasing power of money.

CPI vs RPI in the UK

The Consumer Prices Index (CPI) is the main UK inflation measure. RPI is older and includes housing costs but is less commonly used for official policy.

Why Inflation Matters

Inflation affects salaries, savings, pensions, mortgages and everyday living costs.

Beating Inflation

Investments and higher-interest savings aim to grow faster than inflation to preserve purchasing power.
