What is CPI?

UK inflation fell to 3.2% in November, meaning price growth slowed for a second consecutive month.

While November’s report seems to suggest inflation is on the way down, there is still some work to be done before it reaches the Bank of England’s target of 2%.

What time is CPI released in the UK?

The ONS releases the latest CPI data at 7am once a month. The reports can be accessed by going onto the ONS website and clicking on its release calendar.

All published inflation reports, as well as pages for upcoming ones, are listed there. The report will be titled, “Consumer price inflation, UK”, followed by the month and year in question.

If you do not want to trawl through the data yourself, MoneyWeek reports on each month’s inflation data, bringing you the latest news and expert commentary, and explains what it means for you.

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 typical basket of household goods and services – from eggs, flour and milk to hotel costs, restaurants and air fryers – and tracking how their prices change.

The CPI basket of goods is adjusted once a year to reflect current trends in consumption. For example, VR headsets and yoga mats were added to the basket in 2025, while oven-ready gammon joints and DVD rentals were removed.

The Bank of England keeps a close eye on CPI when setting interest rates. If inflation is too high, the Bank raises interest rates to slow consumer spending and cool the economy.

This works in bringing 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 pushes prices back up.
