Released: 15 January 2013 Download PDF

Key points

  • The Consumer Prices Index (CPI) annual inflation stands at 2.7% in December 2012, unchanged for the third month in a row. At a more detailed level, there were significant upward and downward pressures on the index
  • The largest upward pressure came from the price increases in gas and electricity bills
  • Air fares provided the largest downward pressure, with prices rising at a far slower rate than a year ago
  • The CPI stands at 125.0 in December 2012 based on 2005 = 100
  • The Retail Prices Index (RPI – see background note 1) annual inflation stands at 3.1% in December 2012, up from 3.0% in November. Utility bill increases were the largest contributor to the rise
  • The RPI stands at 246.8 in December 2012 based on January 1987 = 100

A brief description of Consumer Price Indices

Consumer price indices measure the change in the general level of prices charged for goods and services bought for the purpose of household consumption in the UK. A convenient way to understand the nature of these indices is to envisage a very large shopping basket comprising all the different goods and services typically bought by households. As the prices of individual items in this basket vary, the total cost of the basket will also vary. The CPI and RPI measure changes in this total cost.

Consumer Prices Index (CPI)

The CPI is the main UK domestic measure of consumer price inflation for macroeconomic purposes. It forms the basis for the Government’s target for inflation that the Bank of England’s Monetary Policy Committee (MPC) is required to achieve. Since April 2011 the CPI has also been used for the indexation of benefits, tax credits and public service pensions.  However from April 2013 certain working age benefits and tax credits will increase by 1% for each of the next three years.

This section shows the 1-month and 12-month percentage change (the amount by which the figures have increased or decreased compared with a month ago and a year ago respectively). Figure A shows the 12-month percentage change for the CPI. Table A shows the CPI index values plus the 1-month and 12-month percentage changes.

The CPI rose by 0.5% between November and December 2012 compared with a rise of 0.4% a year ago. These 1-month changes are within the normal range for a November to December movement. Between 1996 and 2010, the 1-month change between November and December has varied between a fall of 0.4% and a rise of 1.0%.

The CPI rose by 2.7% between December 2011 and December 2012. This is unchanged from the 12-month rate between November 2011 and November 2012.

Consumer Prices Index (CPI): Briefing on the monthly movement between November and December 2012

This section explains the change in the CPI between the latest two months. Table B shows the 1-month percentage change for each of the CPI divisions.  Figure B shows the contribution of each division to the overall 1-month change.

The CPI rose by 0.5% between November and December this year. The largest upward contributions to the 1-month change came from:

  • housing & household services: prices, overall, rose by 2.0% between November and December, contributing 0.28 percentage points to the total CPI 1-month change. The upward pressure came from gas and electricity bills with a number of companies increasing their prices this month.

  • food & non-alcoholic beverages: prices, overall, rose by 1.2% between November and December this year, contributing 0.14 percentage points to the total CPI 1-month change. Fruit, meat, vegetables and dairy products were the main contributors. This increase is slightly smaller than the November to December increases witnessed in the last couple of years.

  • transport: prices, overall, rose by 0.7% between November and December, contributing 0.12 percentage points to the total CPI 1-month change. Nearly all of the upward pressure came from air fares. This was partially counterbalanced by a downward pressure from motor fuels.

  • furniture & household goods: prices, overall, rose by 1.3% between November and December, contributing 0.08 percentage points to the total CPI 1-month change. The majority of the upward contribution came from furniture and carpets.

 The largest downward contribution to the 1-month change between November and December came from:

  • clothing & footwear: prices, overall, fell by 1.5% between November and December, contributing -0.10 percentage points to the total CPI 1-month change. Garments accounted for the vast majority of the downward contribution.

Consumer Prices Index (CPI): Briefing on the change to the 12-month rate between November and December 2012

This section explains how the CPI 12-month rate (this month’s CPI compared with the CPI for the same month a year ago) has changed between the latest two months. Figure C shows the contribution of each CPI division to the overall change in the 12-month rate.

The change in the CPI 12-month rate is calculated by comparing the price changes between the latest two months and the same two months a year ago. The CPI rose by 0.5% between November and December 2012 compared with a rise of 0.4% between the same two months in 2011. The slight difference in the monthly movements was not sufficient to change the 12-month rate, meaning that the CPI remained at 2.7% for the third month in succession.

While there was no change overall to the CPI 12-month rate, at a more detailed level, there were significant upward and downward pressures on the index.

The most significant upward contributions to change in the CPI 12-month rate between November and December 2012 came from:

  • housing & household services: prices, overall, rose by 2.0% between November and December 2012, compared with a smaller increase of 0.2% in 2011. This contributed 0.26 percentage points to the change in the CPI 12-month rate. The vast majority of the upward contribution came from gas and electricity bills, with a number of the anticipated price increases entering the index this month.

  • clothing & footwear: prices, overall, fell by 1.5%, compared with a larger fall of 2.8% a year ago. This contributed 0.09 percentage points to the change in the CPI 12-month rate. The upward pressure came from garments – in particular jackets, coats and trousers.

By far the most significant downward contribution to change in the CPI 12-month rate between November and December 2012 came from:

  • transport: prices, overall, rose by 0.7% between November and December 2012 compared with a rise of 2.2% in 2011, resulting in a downward contribution of 0.23 percentage points to the change in the CPI 12-month rate. The downward effect came predominantly from air fares, with prices rising by approximately half as much as they did a year ago. The timing of Christmas in relation to the days for which prices were collected may have been a factor. Motor fuels also had a downward contribution. Petrol prices fell by 2.8 pence per litre between November and December 2012 compared with a fall of 1.1 pence per litre a year earlier. Diesel prices fell by 1.4 pence per litre in 2012 compared with a rise of 0.1 pence per litre a year earlier.

Consumer Prices Index (CPI): Briefing on the 12-month rate to December 2012

This section explains how the CPI this month has changed compared with the same month a year ago. Table C shows the 12-month percentage change for each of the CPI divisions.  Figure D shows the contribution of each division to the overall 12-month rate.

The most significant upward contributions to the CPI 12-month rate to December 2012 came from:

  • housing & household services: which contributed 0.6 percentage points, with the majority of the contribution split pretty evenly between rents and home fuel bills.

  • food & non-alcoholic beverages: which contributed 0.4 percentage points, with vegetables, meat and confectionary accounting for three quarters of the contribution.

  • education: which also contributed 0.4 percentage points, with the upward effect coming predominantly from university tuition fees.

  • restaurants & hotels: which also contributed 0.4 percentage points, with the majority of the contribution coming from catering services.

Other measures of Consumer Prices Index (CPI) Inflation

This section shows for other measures of CPI inflation the percentage change over 12-months and the change in the 12-month rate between last month and this month (ie the amount by which the indices have increased or decreased over the year and the change in that relationship between the latest two months).

Figure E compares the 12-month percentage change for the CPI with the 12-month percentage change for these other measures.

Consumer Prices Index excluding indirect taxes (CPIY)

The CPIY is the same as the all items CPI except that it excludes price changes which are directly due to changes in indirect taxation (such as VAT).

In the year to December, the CPIY rose by 2.7%, unchanged for the third month in a row. Therefore, the CPIY and CPI 12-month rates were both unchanged between November and December. There were no changes to indirect taxation that impacted on the CPI between those months.

Consumer Prices Index at constant tax rates (CPI-CT)

The CPI-CT is the same as the CPI except that tax rates are kept constant at the rates they were in the base period (currently January 2012) and vehicle excise duty and television licence fees are excluded.

In the year to December, CPI-CT rose by 2.5%, up from 2.4% in November. Therefore, the CPI-CT 12-month rate rose by 0.1 percentage points between November and December, compared with no change to the CPI. The difference in movement is mainly due to the impact of rounding.

Retail Prices Index (RPI) compared with Consumer Prices Index (CPI)

The RPI is the most long standing measure of inflation in the UK. The RPI, like the CPI, measures inflation with reference to the changing cost of a fixed basket of goods and services. Following a consultation on options for improving the RPI, the National Statistician has concluded that the Carli formula used to produce the RPI does not meet international standards.

This section compares the percentage change over 12-months for the RPI with the comparable change for the CPI and explains any significant differences between the two. Figure F charts the 12-month rates for the CPI and RPI.

In the year to December, the all items RPI rose by 3.1%, up from 3.0% in November. The RPI 12-month rate has therefore increased by 0.1 percentage points between November and December compared with no change in the CPI 12-month rate between the same two months.

Table 5 at the back of the bulletin identifies the main factors contributing to the differences between the 12-month rates for the CPI and the RPI. The rise in the RPI 12-month rate compared with no change in the CPI 12-month rate between November and December is mainly due to:

  • housing components: which increased the RPI 12-month rate relative to the CPI 12-month rate by 0.08 percentage points, but are excluded from the CPI. The increase was split evenly between mortgage interest payments and other housing costs.

Other measures of Retail Prices Index (RPI) Inflation

This section shows for other measures of RPI inflation the percentage change over 12-months and the change in the 12-month rate between last month and this month (ie the amount by which the indices have increased or decreased over the year and the change in that relationship between the latest two months).

Figure G compares the 12-month percentage change for the RPI with the 12-month percentage change for these other measures.

All items Retail Prices Index excluding mortgage interest payments (RPIX)

The RPIX is the same as the all items RPI except for mortgage interest payments, which are excluded from RPIX.

In the year to December, the RPIX rose by 3.0%, up from 2.9% in November. Therefore, the RPIX and RPI 12-month rates both rose by 0.1 percentage points between November and December.

Mortgage interest payments had an upward impact on the change to the RPI 12-month rate in December. This impact was not sufficient to cause a difference between the changes to the RPIX and RPI 12-month rates between those months.

All items Retail Prices Index excluding mortgage interest payments and indirect taxes (RPIY)

The RPIY is the same as the all items RPI except that it excludes price changes which are directly due to changes in indirect taxation (such as VAT) and mortgage interest payments.

In the year to December, the RPIY rose by 3.1%, up from 2.9% in November. Therefore, the RPIY 12-month rates rose by 0.2 percentage points, compared to a 0.1 percentage point rise in the RPI. The difference in the rate of increase is primarily due to rounding.

CPI and RPI Reference Tables, December 2012:  (909.5 Kb Excel sheet) This spreadsheet pulls together the tables that were previously published in the old style Consumer Price Indices Statistical Bulletin and Focus on Consumer Prices publication. A correlation index is included to show the old and new naming conventions and where the tables were previously published, for example: RPI All items 1947-2012 or RP02 and Table 4.1 in Focus is now the new Table 20.

Background notes

  1. National Statistician's announcement on the RPI consultation

    Following a consultation on options for improving the Retail Prices Index (RPI), the National Statistician, Jil Matheson, has concluded that the formula used to produce the RPI does not meet international standards and recommended that a new index be published.

    The National Statistician’s consultation was prompted by the need to address the gap between the estimates produced by the RPI and the Consumer Prices Index (CPI). The ONS research programme found that use of the arithmetic formulation (known as the ‘Carli’ index formula) in the RPI is the primary source of the formula effect difference between the RPI and the CPI, and, that this formulation does not meet current international standards. Therefore, a new RPI-based index will be published from March 2013 using a geometric formulation (Jevons), known as RPIJ.

    In developing her recommendations the National Statistician also noted that there is significant value to users in maintaining the continuity of the existing RPI’s long time series without major change, so that it may continue to be used for long-term indexation and for index-linked gilts and bonds in accordance with user expectations.

    Therefore, while the arithmetic formulation would not be chosen were ONS constructing a new price index, the National Statistician recommended that the formulae used at the elementary aggregate level in the RPI should remain unchanged. The Board of the UK Statistics Authority has accepted these recommendations.

    The National Statistician has also recommended that improvements to the measurement of private housing rents from using an alternative data source should be implemented in the February 2013 RPI, CPI and CPIH indices (published on 19 March 2013). The Board of the UK Statistics Authority has accepted this recommendation and the Bank of England has confirmed that changing the data source for private rents does not constitute a fundamental change to the RPI and is not likely to be materially detrimental to the holders of index-linked gilts. Therefore, the change will go ahead.

  2. New inflation index including owner occupiers’ housing costs to be launched

    On 2 November, ONS announced that a new additional measure of consumer price inflation will be launched which includes owner occupiers’ housing (OOH) costs. The new index, which will initially be known as CPIH, will measure OOH costs using the rental equivalence method. This method uses changes in rental prices to measure the costs of owning, living in and maintaining a property. CPIH will be introduced in March 2013 at the same time as the annual CPI/RPI basket of goods and services is updated.

    ONS published its full response to the public consultation on OOH (together with the Consumer Prices Advisory Committee's annual report for 2012) on 13 November 2012.  

  3. Changes to the Consumer Price Statistics Bulletin

    To coincide with the launch of the new CPIH measure of inflation and the changes resulting from the RPI consultation, the format of the Consumer Price Statistics Bulletin will be changing from March 2013. ONS's intention is to focus on the key figures and improve the depth of analysis on topical issues. If you have any comments or points you would like ONS to consider while it is re-designing the bulletin then please contact ONS at cpi@ons.gsi.gov.uk.

  4. Next month

    Inflation for January 2012 to January 2013 will be published on 12 February 2013. CPI and RPI inflation rates between January 2012 and December 2012 were 3.2% and 3.7% respectively. Inflation rates for January 2012 to January 2013 will take account of price changes between December 2012 and January 2013.

  5. Relevance

    The CPI is the main UK domestic measure of consumer price inflation for macroeconomic purposes. It forms the basis for the Government’s target for inflation that the Bank of England’s Monetary Policy Committee (MPC) is required to achieve. Since April 2011 the CPI has also been used for the indexation of benefits, tax credits and public service pensions.  However from April 2013 certain working age benefits and tax credits will increase by 1% for each of the next three years.

    Internationally, the CPI is known as the Harmonised Index of Consumer Prices (HICP). HICPs are calculated in each Member State of the European Union, according to rules specified in a series of European regulations developed by Eurostat in conjunction with the EU Member States. HICPs are used to compare inflation rates across the European Union. Since January 1999, the HICP has also been used by the European Central Bank (ECB) as the measure of price stability across the euro area.

  6. Methodology

    The CPI and the RPI are compiled using the same underlying price data, based on a large and representative selection of almost 700 individual goods and services for which price movements are measured in around 150 randomly selected areas throughout the UK. Around 180,000 separate price quotations are used every month to compile the indices. The outlets in which the prices are collected are selected randomly. Expenditure weights are held constant for one year at a time.

    The selection of goods and services that are priced to compile the CPI and RPI is reviewed annually. The contents of the 2012 basket are described in an article Consumer Prices Index and Retail Prices Index: the 2012 Basket of Goods and Services (274.7 Kb Pdf) . The expenditure weights used to compile the indices are also updated each year. Additional details of the updated CPI and RPI weights for 2012 are available from the National Statistics website in an article published on 24 April 2012 entitled Consumer Prices Index and Retail Prices Index: Updating Weights for 2012.   

    Rates of change for the CPI are calculated from unrounded index levels, rather than from the published indices, which are rounded to one decimal place. The use of unrounded indices increases the accuracy of the calculation. The unrounded index levels are available on request. By contrast, rates of change for the RPI are calculated from the published rounded indices. 

  7. Reliability

    Once the RPI indices are published they are never revised. CPI indices are revisable although the only time the CPI all items index has been revised was when the index was re-referenced to 2005=100, which took place with the publication of the January 2006 indices.

  8. Comparability

    The CPI’s coverage of goods and services was extended in stages in the areas of health, education, childcare and insurance, with effect from the January 2000, 2001 and 2002 indices. In 2000, there was also a change to the population basis for the weights which was broadened from private households to include expenditure by foreign visitors and residents of institutional households. Further details can be found in a series of articles in the CPI methodology section of the Office for National Statistics website.

    The official CPI series starts in 1996 but estimates for earlier periods are available back to 1988. These estimates are broadly consistent with data from 1996 but should be treated with some caution. An article about historical estimates (106 Kb Pdf) provides more detail.  

    RPI data are available back to 1947 but have been re-referenced on several occasions since then, generally accompanied by changes to the coverage and/or structure of the detailed sub-components. Details of these changes are given in Appendices 1 and 2 of the Consumer Price Indices Technical Manual (754.3 Kb Pdf) .

  9. Other measures of inflation – main uses and methodological details

    Detailed explanations of the main uses and methodology used to construct the ‘other measures of inflation’ included within this statistical bulletin and how they differ from the CPI can be found in Chapters 9 and 10 of the Consumer Price Indices Technical Manual (754.3 Kb Pdf) . In addition this article 'How ONS consumer price statistics are used' provides further details of how consumer price statistics are used more generally.

    • All items Retail Prices Index (RPI): the RPI is the most long-standing general purpose measure of inflation in the UK. Historically the uses of the RPI include the indexation of various prices and incomes and the uprating of pensions, state benefits and index-linked gilts, as well as the revalorisation of excise duties. Please note, though, that since April 2011 the CPI has been used to uprate benefits, tax credits and public service pensions. In January 2013, the National Statistician concluded that the Carli formula used to produce the RPI does not meet international standards.

    The main differences between the CPI and RPI are:

    • population base: CPI includes all UK private and institutional households and foreign visitors to the UK. The RPI includes private households only and excludes the highest income households and pensioner households mainly dependent on state benefits; these excluded private households account for around 13% of all UK household expenditure 

    • item coverage: the most significant difference is that the CPI excludes a number of items relating to housing costs (such as mortgage interest payments, house depreciation and council tax) that are included in the RPI

    • index methodology – formula: the CPI mainly uses the geometric mean whereas the RPI uses Carli, the arithmetic mean to combine individual prices at the first stage of aggregation. This includes the Carli formula which the National Statistician has concluded doesn't meet the international standards

    • item coding: the CPI uses a standard international classification system whereas the RPI uses a system unique to itself and not used elsewhere. The different approaches reflect the fact that the CPI is used to compare inflation rates across Europe so a standard framework is required; the RPI is mainly used within the UK only

    Here is a breakdown of the differences between the CPI and RPI (62.9 Kb Pdf) annual inflation rates.

    Also available is an explanation of the increased impact that the different formulae used to construct the CPI and RPI (61 Kb Pdf) had on the indices during 2010.

    • All items Retail Prices Index excluding mortgage interest payments (RPIX): this index is the same as the all items RPI but it excludes the mortgage interest payments component

    • All items Retail Prices Index excluding mortgage interest payments and indirect taxes (RPIY): is an index designed to measure movements in ‘core’ prices as the index excludes price changes which are directly due to changes in indirect taxation (for example VAT; excise duties on tobacco, alcohol and petrol; local authority taxation; vehicle excise duty; and television licence fees) and mortgage interest payments. The purpose of the index is to obtain a better indication of inflationary pressures at times when prices are directly influenced by government-driven changes

    • Consumer Prices Index excluding indirect taxes (CPIY):  is an index designed to measure movements in ‘underlying prices’ as it excludes price changes which are directly due to changes in indirect taxation (for example VAT; excise duties on tobacco, alcohol and petrol; vehicle excise duty; and television licence fees). As with the RPIY, its main purpose is to obtain a better indication of inflationary pressures at times when prices are directly influenced by government-driven changes

    • Consumer Prices Index at constant tax rates (CPI-CT): is an index where tax rates are kept constant at the rates as they were in the base period (currently January 2012) and which excludes vehicle excise duty and television licence fees. The analytical value of the CPI-CT is when it is compared with the CPI; differences in the monthly and annual rates of change between the two indices provide an indication of the impact of tax changes on the CPI  

  10. Accessibility

    The most efficient way to access the latest CPI and RPI data and briefing on the new website is via the CPI or RPI key figures on the homepage.

    In response to user feedback, all CPI and RPI data is available in one location. These CPI and RPI Reference Tables (909.5 Kb Excel sheet) are provided via a 'printer friendly' excel file.

    To further help users, very detailed CPI data are now available including the individual price quotes and item indices that underpin the CPI. Please note that the data that are published are at a level which means that no individual retailer or service provider will be able to be identified. The data published covers January 1996 to September 2012. These data are updated once a quarter with around a two month lag with the latest CPI publication. For example, the data will next be updated when the February CPI is published on 19 March 2013, at which point the detailed data published will be extended to December 2012.

    This bulletin includes the December 2012 data, collected on 11 December 2012. Future publication dates (43.6 Kb Pdf) for this Statistical Bulletin are available (now includes dates to January 2014). 

    The European Commission (Eurostat) releases figures for the Harmonised Index of Consumer Prices (HICP) for the month of December 2012 for EU Member States, together with an EU average, on 16 January 2013. Further information on HICP for the European Union, Eurozone and other EU Member States is available from Eurostat's HICP web page.  

  11. Further information

    Andrew Dilnot, Chair of the UK Statistics Authority, reported to the House of Commons Public Administration Select Committee in September 2012 that, once the current price indices work programme had concluded, the Authority would undertake a wider review of the governance arrangements and structures supporting the production of price indices to ensure that these statistics best meet user needs in the future.

    Accordingly, once the National Statistician’s recommendations have been implemented in March 2013, the Authority will appoint an independent expert to lead this broader review, and to report to the Board of the Authority. The Authority will publish a further statement about the review in due course.

    As with all National and candidate National Statistics, the new suite of inflation statistics will be subject to independent assessment by the Authority under the supervision of the Authority’s Head of Assessment. The Board of the Authority has asked for this statutory assessment to be completed by summer 2013.

    In addition, in light of the National Statistician’s work programme and the methodological shortcomings now known to be associated with the RPI, the Board of the Authority has asked that these statistics should be re-assessed immediately to determine whether or not they merit continued designation as National Statistics.

    Once statistics have been designated as National Statistics it is a statutory requirement that the Code of Practice shall continue to be observed.
