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 and where are prices heading?
The UK’s rate of inflation slowed to 2.6% in the 12 months to June, as falling motor fuel and food prices helped push price growth down.
The latest reading from the Office for National Statistics (ONS) showed inflation, as measured by the Consumer Prices Index (CPI), is now at its lowest level since March 2025 – well over a year ago.
The pause in the Iran war in June led to a fall in the price of oil and therefore motor fuels and other derivatives.

Inflation was also pushed down as food and non-alcoholic drink inflation slowed to just 1.7%, the lowest level since August 2024.
Although June’s figures look more positive, most economists still expect inflation to rise again in the second half of the year as higher energy prices are forecast to hit households and the fallout from the Iran war will continue to be felt.

All key macroeconomic data from the ONS is published at 7am – this includes GDP, labour market and wage data.
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.
