The Office for National Statistics is due to publish the UK’s September inflation bulletin today, 14 October 2026. The figure may help households, borrowers and savers understand how prices are changing; check the ONS release for the published result and compare it with August only once both figures are confirmed. The scheduled release is not itself evidence of what inflation did or what the Bank of England will decide.

The September CPI figure is due from ONS today

The ONS release page schedules the Consumer Prices Index bulletin for September 2026 for 14 October. The evidence available against the latest official page confirms the release date, but does not provide the September result or the previous month’s figure. Those numbers should be taken from the bulletin once it is published.

A new reading can be discussed alongside forecasts, but forecasts are estimates made before the data arrives. They are not observed inflation. Any same-day market or Bank of England commentary should also be attributed to its source and kept distinct from the ONS result.

What the Consumer Prices Index measures

The Consumer Prices Index, or CPI, tracks changes over time in the prices of a representative basket of goods and services bought by households in the United Kingdom. The annual rate compares prices with the same month a year earlier; the monthly rate compares them with the previous month. These are different comparisons and can move differently.

CPI is an average measure. It does not describe every household’s spending or the price change for every item. A household that spends more on a category whose prices rise quickly may feel a different effect from the headline rate. The bulletin’s detail on categories can help show which parts of the basket contributed to the overall movement.

What the release could mean for bills and savings

Inflation measures the pace at which prices are changing, not whether prices have returned to an earlier level. If the annual rate falls, that generally means prices are rising more slowly than a year before; it does not, by itself, mean that everyday goods and services have become cheaper.

For household budgets, the practical question is how the new data compares with the costs a household actually faces, such as food, transport, energy and housing-related spending. CPI is useful economic context, but it is not a personal bill calculator and does not establish what any individual’s next bill will be.

Borrowers and savers may watch inflation because it informs the wider economic picture considered by the Bank of England. The CPI release alone does not determine an interest-rate decision. Loan and savings rates depend on providers’ terms and wider financial conditions, so readers should check their own account or agreement before making a decision.

Compare the result with August after publication

Once the bulletin is live, readers can compare the September annual and monthly rates with the corresponding figures in the previous release. Check that each comparison uses the same measure and period: an annual rate should be compared with the previous annual rate, and a monthly rate with the previous monthly rate.

The ONS bulletin should also be checked for category-level detail and any explanation of what drove the movement. A change in the headline rate is a measured result; an explanation of its causes requires looking at the components and the ONS commentary. Neither, by itself, proves where prices or interest rates will go next.

Check the ONS bulletin and rate commentary today

Start with the ONS September 2026 consumer price inflation bulletin for the published figures, definitions and component detail. Then look for any same-day Bank of England statement or clearly attributed market commentary if you want context on how the release is being interpreted.

For a household decision, compare the data with your actual budget, bill notice, mortgage or savings terms. Revisit the ONS page when the bulletin is available, and keep any forecast or rate outlook separate from the statistics it was made to anticipate.
