The Office for National Statistics is scheduled to publish the UK’s September 2026 inflation figures at 07:00 UK time on 19 October. Households, borrowers and businesses can use the release to see how measured prices changed; check the published CPI and core CPI figures, then consult the Bank of England’s latest policy information before drawing conclusions about bills or interest rates.

What the September release will show

The ONS release page schedules the consumer price inflation bulletin for this morning. The confirmed update is the publication of new September data. The available information here does not include the bulletin’s figures, so it cannot establish whether inflation rose or fell, or how the results compare with August.

Once published, the ONS tables are the place to check the September CPI and core CPI rates and their previous-release values. Compare figures on the same basis and note whether each is an annual rate or a monthly change. A single headline number does not describe every item in a household’s budget.

CPI	September rate and the comparable figure from the previous release
Core CPI	September rate and the comparable figure from the previous release

CPI and core CPI measure different price baskets

The Consumer Prices Index (CPI) tracks changes over time in the prices of a basket of goods and services. The annual CPI rate compares prices with the same month a year earlier; a monthly rate compares with the previous month. Those comparisons answer different questions, so check the label attached to each ONS figure.

Core CPI is a narrower measure that excludes some components, commonly including energy and food, to help show price movements beyond those often-volatile items. It is not a measure of the full cost of living: households still pay for food and energy, and their own spending patterns may differ from the index basket.

What the figures can and cannot tell you about bills

An inflation rate describes how prices changed across a measured basket over a stated period. It does not mean that every price changed by that rate, that prices are falling if inflation slows, or that a household’s bills will move in line with CPI. A lower annual rate can still mean prices are higher than a year earlier.

For a practical household view, compare the categories that matter to you with your own bills and receipts. The national figures provide context, but they cannot predict an individual’s next energy charge, rent, food shop or mortgage payment.

Check the Bank of England before judging rate expectations

Inflation data can inform discussion of interest rates, but one release does not automatically trigger a Bank of England decision. The outcome depends on the wider economic picture and the Bank’s policy process. A CPI reading alone cannot confirm what the next rate decision will be or when it will happen.

After the ONS bulletin appears, verify the September and previous-release figures in its tables. For interest-rate context, check the Bank of England’s latest policy statement and decision information. Those are the next useful checks for readers weighing household costs and borrowing expectations.
