The Office for National Statistics is scheduled to publish the UK’s September consumer price inflation figures at 07:00 UK time on 19 October. Households, borrowers and businesses can use the release to see how prices changed over the year and month; check the published CPI and core CPI tables, then compare them with the Bank of England’s latest policy information before drawing conclusions about bills or interest rates.

What the September ONS release will show

The ONS release page schedules its September 2026 consumer price inflation bulletin for 19 October at 07:00. That confirms when new official data is due, but the information available here does not include the published figures. No direction or size of change can be stated without the bulletin’s tables.

When the release is available, look for the annual and monthly rates for the Consumer Prices Index (CPI), as well as the core CPI measures. Compare each with the corresponding figure in the previous release. An annual rate compares prices with the same month a year earlier; a monthly rate compares with the previous month. They answer different questions, so one should not be substituted for the other.

CPI and core CPI measure different price patterns

CPI tracks changes in the prices of a representative basket of goods and services bought by households. The overall rate gives a broad measure of price changes, but it does not describe every household’s spending or the price movement of every item.

Core CPI is a narrower measure intended to show underlying price patterns by excluding some more volatile components. Check the ONS bulletin for the precise definition and reported core measures. Core inflation can help explain whether price pressures extend beyond components that move sharply, but it is not a direct measure of any one household’s cost of living.

Compare like with like before reading a trend

Use the ONS tables to compare September with the previous release, checking the same measure and time period. For example, compare the September annual CPI rate with the prior month’s annual CPI rate, rather than comparing an annual rate with a monthly one. The same care applies to core CPI.

A single month’s reading can change the picture, but it does not by itself establish a lasting trend. The release provides a snapshot of measured price changes; it cannot tell a reader exactly how their own rent, food shop, energy use or other bills will change. For earlier context on how inflation data shaped expectations ahead of a Bank of England decision, see June CPI figures.

Inflation data does not set mortgage rates automatically

The Bank of England considers inflation alongside other information when setting monetary policy. A new CPI figure may affect expectations, but it does not automatically trigger a rate decision or determine mortgage costs. Mortgage payments also depend on a borrower’s deal, lender terms and whether the rate is fixed or variable.

After checking the ONS figures, consult the Bank of England’s latest policy announcement for its current rate and explanation. For household bills, look at the specific prices, tariffs or contracts that apply to you. The next useful check is the published September bulletin itself, followed by any subsequent Bank of England decision or guidance.
