Image .csv .xlsThe Consumer Prices Index including owner occupiers' housing costs (CPIH) rose by 2.8% in the 12 months to June 2026, down from 3.0% the previous month (Figure 1). The 12-month rate for June was the lowest recorded since September 2024, when it was 2.6%.
On a monthly basis, CPIH rose by 0.2% in June 2026, compared with a rise of 0.3% in June 2025.
The Consumer Prices Index (CPI) rose by 2.6% in the 12 months to June 2026, down from 2.8% the previous month. The 12-month rate was also 2.6% in March 2025 and it was last lower in December 2024, when it was 2.5%.
On a monthly basis, CPI rose by 0.1% in June 2026, compared with a rise of 0.3% in June 2025.
The main drivers of the annual inflation rate for CPIH and CPI are the same where they are common to both measures. However, the owner occupiers' housing (OOH) costs component accounts for approximately 18% of the CPIH and is the main driver for differences between the CPIH and CPI inflation rates.
This makes CPIH our most comprehensive measure of inflation. We cover this in more detail in Section 4: Latest movements in CPIH inflation and provide a commentary on the CPI in Section 5: Latest movements in CPI inflation. We also cover both CPIH and CPI in Section 3: Notable movements in prices, though the figures reflect CPIH.

Image .csv .xlsFigure 2 shows the contributions from the 12 divisions to the change in the annual Consumer Prices Index including owner occupiers' housing costs (CPIH) inflation rate between May and June 2026. These sum to the change in the annual rate, from 3.0% to 2.8%, between these months.
The decrease in the 12-month rate between May and June 2026 reflected downward contributions from five divisions, partially offset by upward contributions from three divisions. The largest downward contribution came from transport, particularly motor fuels. There were no large, offsetting upward contributions.
Transport
Prices in the transport division rose overall by 5.7% in the 12 months to June 2026, down from 6.8% the previous month (Figure 3). On a monthly basis, prices fell by 0.3% in June 2026, compared with a rise of 0.7% a year ago.

Download this chart Figure 3: Transport inflation rate slowed in June 2026
Image .csv .xlsThe largest downward effect behind the slowing in the transport annual rate came from motor fuels, particularly diesel.
The average price of diesel fell by 10.7 pence per litre between May and June 2026, compared with a fall of 0.6 pence per litre between May and June 2025. The average price stood at 176.4 pence per litre in June 2026.
Petrol prices fell by 2.1 pence per litre in June 2026, compared with a fall of 0.5 pence per litre in June 2025. The average price stood at 155.3 pence per litre in June 2026. This is the first time petrol prices have eased since the start of the conflict in the Middle East, on 28 February 2026.
These movements resulted in overall motor fuel prices rising by 21.3% in the 12 months to June 2026, compared with a rise of 24.6% in the 12 months to May, which was the highest recorded rate since September 2022.
Within transport, there was a smaller downward effect from vehicle maintenance and repair. Prices fell by 0.2% in June 2026, compared with a rise of 2.0% in June 2025. The movements were caused by price changes for roadside recovery services.
Food and non-alcoholic beverages
Food and non-alcoholic beverage prices rose by 1.7% in the 12 months to June 2026, down from 2.2% the previous month (Figure 4). The annual rate in June was the lowest since August 2024, when it was 1.3%. On a monthly basis, food and non-alcoholic beverage prices fell by 0.2% in June 2026, compared with a rise of 0.3% a year ago.

Download this chart Figure 4: Food and non-alcoholic beverages inflation rate was at its lowest since August 2024
Image .csv .xlsThere were small downward effects behind the change in the annual rate from 5 of the 11 detailed classes. The largest of these effects came from sugar, jam, syrups, chocolate and confectionery, for which prices of chocolate fell by more in June 2026 than June 2025. This class made a downward contribution of 0.02 percentage points to the change in the CPIH inflation rate.
Other slightly smaller downward effects came from oils and fats (particularly margarine and other vegetable oils), meat (particularly beef), dairy, and vegetables. Prices of oils and fats, and dairy, fell in June 2026, compared with a price rise and little change a year ago, respectively. Meat and vegetable prices rose in June 2026 but by less than in June 2025.
The other six detailed classes within food and non-alcoholic beverages had little effect on the change in the headline rate. These were bread and cereals, fish, fruit, other food products, hot beverages, and soft drinks.
Clothing and footwear
Clothing and footwear prices fell by 0.5% in the 12 months to June 2026, compared with a rise of 0.2% the previous month.
On a monthly basis, prices fell by 1.2% in June 2026, compared with a smaller fall of 0.4% in June 2025. Prices tend to fall in June as the summer sales season begins, and the movements reflect changes in the proportion of discounted prices in the datasets. This proportion rose between May and June this year by more than the rise seen over the same period a year ago.

The core CPIH annual inflation rate was 2.8% in June 2026, the same rate as in April and May. These are the joint lowest rates since September 2021.
The CPIH all-goods index rose by 1.7% in the 12 months to June 2026, down from 2.0% the previous month. There were large downward contributions to the change in the annual rate from energy, particularly motor fuels and domestic heating oil, and from food, alcoholic beverages and tobacco.
The CPIH all-services index rose by 3.6% in the 12 months to June 2026, unchanged from the 12 months to May. The upward and downward contributions to the change in the annual rate were small and offset one another. The largest downward contribution came from services for personal transport equipment, and the largest upward contribution came from package holidays and accommodation.

The contribution of each category to the annual rate depends on the price movement in that category and its weight, which is updated annually.
The largest positive contribution to the CPIH annual inflation rate came from housing and household services. The division has made the largest contribution for the last 24 months, starting from July 2024. However, its contribution has eased from a recent high in April 2025, and was unchanged between May and June 2026. The contributions in the latest two months were jointly the smallest since June 2024.
The contribution from food and non-alcoholic beverages has also broadly eased over recent months. It was 0.15 percentage points in June 2026, the smallest since August 2024.
Similarly, the contribution from alcohol and tobacco has eased over the last year. It was 0.06 percentage points in June 2026, the smallest since July 2021, when it was also 0.06 percentage points. The contribution was last smaller in March 2020.
In contrast, the contribution from restaurants and hotels has risen to 0.49 percentage points in June 2026, the largest contribution since October 2024.

The annual contribution from OOH costs rose slightly, to 0.58 percentage points, in June 2026. This was the first rise between months since January 2025 and followed 16 consecutive decreases. Although the current contribution was larger than the previous month's, it was smaller than the recent high of 1.31 percentage points in January 2025.
The annual contribution from electricity, gas and other fuels was negative 0.17 percentage points in June 2026, unchanged from May. An easing in the contribution from domestic heating oil was offset by smaller upward contributions from classes such as electricity.
Back to table of contents5. Latest movements in CPI inflation
While the Consumer Prices Index including owner occupiers' housing costs (CPIH) is our most comprehensive measure of consumer price inflation, the Consumer Prices Index (CPI) is based on a harmonised methodology developed by Eurostat. This enables international comparisons to be drawn. It is also used to set the operational inflation target for UK monetary policy, and to uprate working-age benefits and tax credits. More information on the use cases for our consumer price inflation statistics can be found in our Measuring changing prices and costs for consumers and households: December 2023 article.
Figure 8 shows annual CPI inflation for the UK compared with the EU average and selected G7 countries. While the UK CPI is produced on a comparable basis with EU countries, the US Harmonised Index of Consumer Prices (HICP) differs in some respects. More information is available in Note 1 to Figure 8.
The UK's CPI annual inflation rate of 2.6% was lower than the EU rate (2.9%) but higher than that for France (2.0%) and Germany (2.4%) in June 2026.

7. Glossary
Annual inflation rate
The most common approach to measuring inflation is the 12-month or annual inflation rate, which compares prices for the latest month with the same month a year ago. In any given month, the annual rate is determined by the balance between upward and downward price movements across the range of goods and services included in the index.
Consumer price inflation
Consumer price inflation is the rate at which the prices of goods and services bought by households rise or fall. It is estimated by using price indices. For an overview of the range of indices available and their uses, please see our Consumer price indices, a brief guide: 2026 article and our Measuring changing prices and costs for consumers and households: December 2023 article.
CPIH
The Consumer Prices Index including owner occupiers' housing costs (CPIH) is the most comprehensive measure of inflation. It extends the Consumer Prices Index (CPI) to include a measure of the costs associated with owning, maintaining and living in one's own home, known as owner occupiers' housing (OOH) costs, along with Council Tax. Both are substantial expenses for many households and are not included in the CPI.
CPI
The CPI is a measure of consumer price inflation produced to international standards, and it is based on European regulations for the Harmonised Index of Consumer Prices. The CPI is the inflation measure used in the government's target for inflation.
The CPI is produced at the same level of detail as the CPIH in our accompanying Consumer price inflation dataset and in our accompanying Consumer price inflation time series.
Owner occupiers' housing costs
OOH costs are the costs of housing services associated with owning, maintaining and living in one's own home.
RPI
The Retail Prices Index (RPI) and its subcomponents do not meet the required standard for designation as accredited official statistics. In recognition that the index continues to be widely used in contracts, we continue to publish the RPI, its subcomponents, and RPI excluding mortgage interest payments (RPIX). To view the all-items RPI, please see the data time series section of the Inflation and price indices area of our website. The annual RPI inflation rate was 3.0% in June 2026.
The UK Statistics Authority (The Authority) and HM Treasury launched a consultation in 2020 on The Authority's proposal to address the shortcomings of the RPI. From 2030 (at the earliest), as outlined in The Authority's response to the joint consultation on reforming the methodology of the Retail Prices Index, the CPIH methods and data sources will be introduced into the RPI. Additionally, the supplementary and lower-level indices of the RPI will be discontinued.

Great British Summer Savings
The UK Government's Great British Summer Savings scheme, announced on 21 May 2026, took effect on 25 June. This was after the collection period for our June 2026 data and does not affect the indices this month. The scheme potentially affects a small number of low-level items in the inflation baskets, such as attractions and admissions to cultural events, whose prices are being collected for July.
Introducing scanner data into consumer price inflation statistics
We introduced scanner data for approximately 50% of the grocery market with the February 2026 index, published on 25 March 2026. Instead of collecting 25,000 prices per month directly from shops by price collectors, we are now using approximately 300 million price points derived from sales of over a billion units of products per month, collected directly from supermarket scanners at the checkouts or online. For the remaining 50% of the groceries market, we continue to manually collect prices in-store and online.
For comparison, we produced the all-items headline rates for February 2026 without using scanner data. Based on locally collected grocery data, the Consumer Prices Index including owner occupiers' housing costs (CPIH) rose by 3.3% in the year to February 2026, and the Consumer Prices Index (CPI) rose by 3.1%. These were slightly above the official rates of 3.2% and 3.0%, respectively.
You can find more about this change and how it affects our headline measures of inflation in our Impact analysis on transformation of UK consumer price statistics: January 2026 article.
We also published our Overview of how we use scanner data in consumer price inflation statistics: January 2026 article and our How multilateral index methods help us understand grocery scanner data article, which support user understanding of how we use the data.
Following the Bank of England's response to the proposed changes to the Retail Prices Index (RPI) in 2026 (PDF, 140KB), required under the Statistics and Registration Service Act 2007, this change was included in the RPI released in March 2026. It was also incorporated into the Household Costs Indices (HCIs) published on 28 May 2026.
This followed some changes introduced with the February 2025 consumer price indices in March 2025, as a necessary step towards incorporating scanner data. At that point, the process for aggregating the detailed information changed. Goods and services were allocated into "consumption segments" for different categories of expenditure.
In some cases, we defined these consumption segments to correspond to one "item" for which we track prices over time. However, in cases where more comprehensive source data were going to become available, a consumption segment was set up to include much more than just one item. There is more information on the use of consumption segments in our Introducing alternative data into consumer price statistics: aggregation and weights article. For simplicity, we continue to refer to "items" in our statistical bulletin and detailed briefing note.
Changes to published microdata
Despite the benefits of introducing scanner data into the consumer price indices, we can no longer publish the price quote data for food and non-alcoholic beverages, alcohol and tobacco (Divisions 1 and 2 of the CPIH and CPI), or the equivalent categories of RPI in our Consumer price inflation consumption segment indices and price quotes dataset. This is because of our data-sharing agreements with retailers.
Instead, we have developed new aggregate output statistics to meet the needs of users. We have improved the granularity and accuracy of our Shopping prices comparison tool. We now provide average prices for more specific product types, such as "Microwave rice" and "Basmati rice". Under the previous, broader definitions (such as "rice, in all forms") we were unable to produce average prices. Units of measurement are also now included, making comparisons more meaningful and easier to interpret.
We are also publishing regional consumption segment indices and weights, and counts of indicator marker codes (for example, sales and recoveries) that are manually collected as part of the traditional data collection. We first published these from March 2026, with the release of the February 2026 indices. Further outputs will be introduced later in 2026.
More information on the new outputs is available in our Changes to the provision of microdata outputs for consumer price inflation statistics: January 2026.
Households and the cost of living
To assist individuals in understanding how the rise in inflation affects their expenditure, we have produced a personal inflation calculator. The calculator allows users to enter the amount they spend across either a reduced or a wide range of categories, to produce an estimate of their personal inflation based on those spending patterns.
Our Shopping prices comparison tool shows how the average prices of items have changed over time. Please note that the newly introduced consumption segments for food, drink and tobacco will not have data before 2025 in the tool. However, the historical average prices for food, drink and tobacco items, that were in the tool before the update in 2025, can be found in our Shopping prices comparison tool data download before the 2025 update.
Please also note that Table 55 in our historical Consumer price inflation dataset, which provided time series of prices for petrol and diesel, has not been published since 19 February 2025, and the two series have been discontinued. Historical average prices are still available from the time series explorer function on our website, using the four-character identifiers CZMK for petrol and CZML for diesel.
On 28 May 2026, we published our quarterly Household Costs Indices (HCIs) for UK household groups bulletin. The HCIs reflect how different types of households experience changing prices, and they differ from CPIH and CPI. The CPIH and CPI are based on recognised economic principles and provide an aggregate measure of inflation for household spending in the UK.
The HCIs are official statistics in development and this release included new estimates for January to March 2026. This release uses updated 2025 weights. It has not been possible to update to 2026 weights in line with the standard methodology for consumer prices. This is because of delays in processing the underlying survey data and the need for further quality assurance. We will update the weights as soon as the data are available to use.
The latest HCI dataset also includes scanner data for the first time.
Passenger transport by air
A monthly index for passenger transport by air is included in the monthly consumer price inflation dataset. From March 2025, we also began publishing a set of subindices and weights on an annual basis. We updated our Domestic, European and long-haul airfares consumer prices subindices and weights dataset on 25 March 2026 with data for March 2025 to February 2026, and a longer historical time series back to 2007. From March 2026, we have also started to release quarterly and annual average air fares, again on an annual basis. The analyses are released in the user requested data section of our website.
Classification of Individual Consumption According to Purpose
The Classification of Individual Consumption According to Purpose (COICOP) is the classification that underpins some of the main statistics that we produce. To reflect changes in household expenditure patterns since its inception in the late 1990s, the classification was updated in 2018 (PDF, 1,286KB).
The UK currently uses the version of COICOP introduced in 1999, which was updated in 2017 to add additional detail at the subclass level. However, we plan to have implemented the updated COICOP 2018 by 2029, as referenced in Section B4 of our Economic statistics plan and Section 5 of our Economic statistics progress report. We will also consider re-referencing the CPI as part of the move to the new classification and will provide users with full details of our plans, once finalised.

Weights for 2026 consumer price inflation statistics
In line with usual practice at the start of each year, the expenditure weights used in compiling the CPIH and CPI were calculated using updated spending information. The first update of weights was implemented with the January indices. The second update was introduced, along with the usual basket update, with the February indices released in March. We published our Consumer price inflation, updating weights: 2026 article and our Consumer price inflation basket of goods and services: 2026 article on 16 March 2026.
The 2026 weights for CPIH and CPI were calculated using national accounts household final consumption expenditure (HHFCE) data for 2024. They reflect our most comprehensive and complete estimate of the latest household spending at the time of the weights update. This is in line with our standard methodology. More information is available in our Consumer price inflation, updating weights articles.
The weights for the RPI were also updated and introduced with the February 2026 index.
Consumer price inflation historical estimates, UK, 1950 to 1988
On 18 May 2022, we published our Consumer price inflation, historical estimates, UK, 1950 to 1988 - methodology and our Consumer price inflation, historical estimates and recent trends, UK: 1950 to 2022 article. These include new estimates of CPIH and improved estimates of CPI for 1950 to 1988. These estimates (published in response to user need for a longer series) are indicative and are for analytical purposes only. They are not intended for official use and do not constitute part of the accredited official statistics series.
Previously, in December 2018, we published our Consumer Prices Index including owner occupiers' housing costs (CPIH) historical series: 1988 to 2004 article. These series are also not classed as accredited official statistics, reflecting the historical uncertainty around the backcasts.
Methodology information
The consumer price indices are based on prices collected manually from outlets around the country, information collected centrally over the internet and by phone, and, from February 2026, data collected from supermarket scanners at the checkouts or online. The traditionally sourced data used in this release were collected on or around 16 June 2026.
An overview of consumer price statistics is given in our Consumer price indices, a brief guide: 2026 article. The concepts and methodologies underpinning the indices in more detail are covered in our Consumer prices indices technical guidance methodology.
Information on the users and uses of these statistics, and the characteristics of the different measures of inflation related to potential use, is included in our Users and uses of consumer price inflation statistics: July 2018 update methodology.
Strengths and limitations
In our Measuring changing prices and costs for consumers and households article, we illustrated our approach to the process using three "use cases" and described how they relate to the measures published and under development.
The three cases refer firstly to the CPIH as our lead measure of inflation, based on economic principles. They also refer to the HCIs as a set of measures that reflect the change in costs and prices experienced by different households, and the RPI as a legacy measure that is required to meet existing user needs. The issues with the RPI are described in our Shortcomings of the Retail Prices Index as a measure of inflation article.
Accredited official statistics
These accredited official statistics were independently reviewed by the Office for Statistics Regulation in July 2017. They comply with the standards of trustworthiness, quality and value in the Code of Practice for Statistics and should be labelled "accredited official statistics".
Revisions and correction of errors policies for consumer price inflation statistics
Our Revisions and correction of errors policies for consumer price inflation statistics are stated separately to highlight the differences between them. Within each policy, there is information on how the policy is applied, in what circumstances users will be notified and how users will be notified. This policy replaces our previous Revisions policy for consumer price inflation statistics article, published in March 2017.
