On a monthly basis, CPIH rose by 0.2% in November 2024, compared with a fall of 0.1% a year earlier.
The owner occupiers' housing costs (OOH) component of CPIH rose by 7.8% in the 12 months to November 2024, up from 7.4% in the 12 months to October. This is the highest annual rate since February 1992 in the constructed historical series. OOH costs rose by 0.8% on the month, compared with a 0.4% increase a year earlier.
The Consumer Prices Index (CPI) rose by 2.6% in the 12 months to November 2024, up from 2.3% in October, but well below its recent peak of 11.1% in October 2022.
On a monthly basis, CPI rose by 0.1% in November 2024, compared with a fall of 0.2% a year earlier.
The main drivers of the annual inflation rate for CPIH and CPI are the same where they are common to both measures. However, the OOH component accounts for approximately 16% 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 October and November 2024. These sum to the change in the annual rate between the latest two months, that is, the rise from 3.2% to 3.5%.
The increase in the rate into November 2024 reflected upward contributions from seven divisions partially offset by a small downward contribution from restaurants and hotels. The largest upward contributions came from transport, and housing and household services.
Transport
Overall prices in the transport division fell by 1.1% in the year to November 2024, compared with a fall of 2.0% in the year to October (Figure 3). On a monthly basis, prices fell by 0.8% in November 2024 compared with a fall of 1.7% a year ago.
The change in the annual rate was mainly the result of upward effects from motor fuels and second-hand cars, partially offset by a downward effect from air fares.
The average price of petrol rose by 0.8 pence per litre between October and November 2024 to stand at 134.8 pence per litre, down from 151.0 pence per litre in November 2023. Diesel prices rose by 1.4 pence per litre in November 2024 to stand at 140.5 pence per litre, down from 159.0 pence per litre in November 2023. These movements resulted in overall motor fuel prices falling by 10.9% in the year to November 2024, compared with a fall of 13.7% in the year to October.
Prices of second-hand cars fell by 0.2% between October and November 2024, compared with a fall of 2.1% a year ago. On an annual basis, prices fell by 1.3% in the year to November 2024, compared with a fall of 3.2% in the year to October. The annual rate has been negative for 16 consecutive months, though it has grown less negative since May this year.

Fares usually fall in November, but the drop in 2024 was the largest November fall since monthly price collection began in 2001 and follows a relatively high figure for October. The movement was largely driven by falls in fares on European routes.
Housing and household services
The annual inflation rate for housing and household services was 5.8% in November 2024, up from 5.5% in October. This compares with a recent peak of 11.8% observed in January and February 2023. On a monthly basis, prices rose by 0.6% in November 2024, compared with a rise of 0.3% a year ago.
The 0.3 percentage point increase in the annual rate between October and November 2024 reflected upward effects from owner occupiers' housing (OOH) costs and, to a lesser extent, actual rentals for housing. OOH costs rose by 7.8% in the year to November 2024, up from 7.4% in October. The latest figure is the highest since February 1992 when the rate was 8.6% in the constructed historical series. The annual rate for actual rentals for housing was 7.6% in November 2024, up from 7.4% in October.
Recreation and culture
Overall prices in the recreation and culture division rose by 3.6% in the year to November 2024, up from 3.1% in the year to October (Figure 4). On a monthly basis, prices rose by 0.1% in November 2024, compared with a fall of 0.4% a year ago.

Download this chart Figure 4: Annual inflation rate for recreation and culture rose in November 2024 but still below the rates seen in 2022 and 2023
Image .csv .xlsThe rise in the annual rate was the result of relatively small upward effects from a variety of the more detailed classes. The largest came from cultural services (particularly admission fees to live music events and theatres) and games, toys and hobbies (particularly computer games). These effects were partially offset by a small downward contribution from recording media, where prices overall fell in November 2024 but rose a year ago. Short-term movements in these three classes should be interpreted with a degree of caution, as the movements depend on the acts that are performing and the composition of bestseller charts.

There were upward contributions to the change in the annual rate from non-energy industrial goods (particularly clothing and footwear goods, and vehicles, spare parts and accessories), energy (from motor fuels) and food, alcoholic beverages and tobacco (from processed food and tobacco).
The CPIH all services index rose by 5.7% in the 12 months to November 2024, slightly up from 5.6% in October. The largest upward contribution to the change in the annual rate came from housing services, principally from owner occupiers' housing costs (OOH).

OOH's contribution rose from 1.19 to 1.27 percentage points between October and November 2024, and was the main influence behind the increased contribution from housing and household services to the annual CPIH inflation rate in November 2024.
Nôl i'r tabl cynnwys5. Latest movements in CPI inflation
While the Consumer Prices Index including owner occupiers' housing costs (CPIH) is our lead and most comprehensive measure of consumer price inflation, the Consumer Prices Index (CPI) is based on a harmonised methodology developed by Eurostat and allows for international comparisons to be drawn. For more information on the use cases for our consumer price inflation statistics, please refer to our Measuring changing prices and costs for consumers and households: December 2023 article.
Figure 8 shows CPI inflation for the UK against the European Union (EU) average and selected Group of Seven (G7) countries. While the UK CPI is produced on a comparable basis with EU countries, the United States Harmonised Index of Consumer Prices (HICP) measure differs in some respects (see Footnote 1 of Figure 8). The UK's CPI inflation rate of 2.6% was above the first (or "flash") estimates of inflation for France (1.7%) and Germany (2.4%) in the 12 months to November 2024. It was also above the United States figure of 2.3%.

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: 2017 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 costs (OOH), along with Council Tax. Both are significant 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 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 dataset and accompanying data time series.
Owner occupiers' housing (OOH) 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) does not meet the required standard for designation as an accredited official statistic. In recognition that it 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 3.6% in November 2024.
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 consultation, 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.

Classification Of Individual Consumption According to Purpose (COICOP)
The Classification of Individual Consumption According to Purpose (COICOP) is the classification that underpins some of the main statistics produced by the Office for National Statistics (ONS). The classification has seen a significant update (PDF, 2.51MB) in recent years to reflect changes in household expenditure patterns since its inception in the late 1990s. The UK currently uses the version of COICOP introduced in 1999.
To ensure the implementation of the new classification is done in a comprehensive and robust manner and while taking into consideration other ONS priorities around the transformation of our main statistics, we will aim to introduce the new classification (COICOP 2018) as soon as possible, as part of our wider plans to implement the updated System of National Accounts (SNA25). This, however, is likely to be later than the date for implementation in some other countries. We will share our implementation plan in due course.
For further information please contact cpi@ons.gov.uk.
Passenger transport by air
While we already publish a monthly index for passenger transport by air, from 26 March 2025 we will also publish annual price indices and weights split by domestic flights, European flights and long-haul flights.
Alternative data sources
We are undertaking a programme of transformation across our consumer price statistics, including identifying new sources, improving methods and developing systems. More information about the project and our ongoing transformation plans can be found in our Research and developments in the transformation of UK consumer price statistics article, released on 1 December 2023. This includes information on the transformation of consumer price statistics on second-hand cars and private rents, which we introduced with the February 2024 index, and our proposed approach to outlier detection in grocery scanner data.
As part of our plans, we updated our transformation overview on 6 August 2024, as well as publishing our updated development plan to outline the rationale for our priorities and their potential impact.
As usual, we welcome your feedback on our work by email to cpi@ons.gov.uk.
Weights for 2024 consumer price inflation statistics
In line with usual practice at the start of each year, the expenditure weights used in compiling the consumer price inflation statistics were updated in March 2024. For the Consumer Prices Index including owner occupiers' housing costs (CPIH) and the Consumer Prices Index (CPI), they were calculated using national accounts household final consumption expenditure (HHFCE) data for 2022. This is in line with our standard methodology of using data lagged by two years.
It differs from the approach used over the last few years, when there were large changes seen in spending patterns because of the coronavirus (COVID-19) pandemic. Over these years, we adjusted the spending data so that the resulting weights were more reflective of the year immediately before use in consumer price inflation. More information on weights updating is available in our Consumer price inflation, updating weights articles.
The weights for the Retail Prices Index (RPI) were also updated for 2024 in line with the practice followed both before and during the pandemic period, with no additional adjustment to the spending data because of any coronavirus effects.
The weights used to produce the CPI and CPIH have historically been rounded to integers as parts per thousand of the all-items indices. From 2024, we are now using unrounded weights in compiling the indices. The RPI continues to be based on integer weights.
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. As a result, the number of average price series in Table 55 in our Consumer price inflation dataset has been reduced to two, covering petrol and diesel, and Table 54 has been discontinued. The average price data originally presented in these tables are currently still available as time series on our website and can be found using the four-character identifiers in Table 55.
On 28 November 2024, 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 differ from CPIH and CPI, which are based on recognised economic principles and which 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 July to September 2024. It was not possible for this latest release to update the weights for 2024 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 ongoing quality assurance. Instead, the most recent estimates have been compiled using the weights for February to December 2023. We aim to update the weights in the second quarter (April to June) of 2025.
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 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 the period 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 statistic series.
Previously, in December 2018, we published our Consumer Prices Index including owner occupiers' housing costs (CPIH) historical series: 1988 to 2004 article. This series is also not an accredited official statistic, reflecting the historical uncertainty around the backcasts.
Pre-release access
The Bank of England was granted exceptional pre-release access to an estimate of consumer price inflation data at 8:30am on Monday 16 December 2024 so that the data were available for the Monetary Policy Committee meeting held on that day. The letters requesting and agreeing to pre-release are available in the Exchange of letters between the Bank of England and the Office for National Statistics for exceptional pre-release access to the Consumer Prices Index and Labour Market Statistics.
Methodology information
The consumer price indices are normally based on prices collected from outlets around the country, supplemented by information collected centrally over the internet and by phone. The figures in this publication use data collected on or around 12 November 2024.
Our Consumer price indices, a brief guide gives an overview of consumer price statistics, while our Consumer prices indices technical manual covers the concepts and methodologies underpinning the indices in more detail.
Our CPIH Compendium provides a comprehensive source of information on the CPIH, focusing on the approach to measuring owner occupiers' housing costs.
Our Users and uses of consumer price inflation statistics: July 2018 update includes information on the users and uses of these statistics, and the characteristics of the different measures of inflation in relation to potential use.
Strengths and limitations
We illustrated our approach to Measuring changing prices and costs for consumers and households most recently in December 2023 using three "use cases", and described how they relate to the measures published and under development.
The three cases refer firstly to the Consumer Prices Index including owner occupiers' housing costs (CPIH) as our lead measure of inflation based on economic principles. They also refer to the Household Costs Indices (HCIs) as a set of measures that reflect the change in costs and prices experienced by different households, and the Retail Prices Index (RPI) as a legacy measure that is required to meet existing user needs. Our Shortcomings of the RPI as a measure of inflation article describes the issues with the RPI.
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".
