Consumer Prices Index release dates: When will next inflation data be published?
The UK’s inflation reports are published monthly. When do they come out?
Inflation data is published every month by the Office for National Statistics (ONS).
The figures show how much prices in the UK have changed in the past 12 months, and highlight the sectors of the economy where inflation is rising or falling.
The ONS publishes inflation figures on the third Wednesday of each month, and the data releases at 7am.

What is CPI and how is it calculated?
CPI, the main measure of inflation used in the UK, tells you how fast the cost of living is increasing (or decreasing).
It is calculated using a basket of typical household goods and services which changes once per year to reflect current trends and consumption. For example, houmous and non-alcoholic beer were added to the basket in 2026.
The Bank of England keeps a close eye on CPI when setting interest rates. If inflation is too high, the Bank may raise interest rates to slow consumer spending and cool the economy.
This works to bring prices down because households have less money to spend when mortgage rates are high and debts are more expensive to repay.
Meanwhile, if inflation is too low, the Bank may reduce interest rates so consumers have more disposable income to spend. Due to the laws of supply and demand, this should push prices back up and stimulate growth in the economy.
