Released: 18 September 2012 Download PDF

Key points

  • The Consumer Prices Index (CPI) annual inflation stands at 2.5 per cent in August 2012, down from 2.6 per cent in July.
  • The largest downward pressures behind the change in the CPI rate came from furniture, household equipment & maintenance, housing & household services (particularly domestic gas) and clothing & footwear. These were partially offset by an upward pressure from transport (particularly motor fuels).
  • The CPI stands at 123.1 in August 2012 based on 2005=100.
  • The Retail Prices Index (RPI) annual inflation stands at 2.9 per cent in August 2012, down from 3.2 per cent in July.
  • The largest downward pressures came from household goods, clothing & footwear and food. The only significant upward pressure came from fares & other travel costs.
  • The RPI stands at 243.0 in August 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.

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. Table A shows the CPI index values plus the 1-month and 12-month percentage changes.

The CPI rose by 0.5 per cent between July and August this year compared with a rise of 0.6 per cent a year ago. The rise this year is within the normal range for a July to August movement. Between 1996 and 2010, the 1-month change between July and August has varied between 0.0 per cent and an increase of 0.6 per cent.

The CPI rose by 2.5 per cent between August 2011 and August 2012. With the exception of the June 2012 inflation figure (2.4 per cent), this is the lowest rate of annual inflation since November 2009.

Consumer Prices Index (CPI): Briefing on the monthly movement between July and August 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 per cent between July and August this year. The largest upward contributions to the 1-month change came from:

  • transport: prices, overall, rose by 1.3 per cent, contributing 0.21 percentage points to the total CPI 1-month change. The largest upward pressures came from motor fuels and air transport. Petrol prices rose by 3.5 pence per litre on the month to stand at £1.35 per litre while diesel prices rose by 3.3 pence per litre to reach £1.40 per litre. As usual, air fares rose between July and August, by 10.2 per cent this year.

  • clothing & footwear: prices, overall, rose by 2.8 per cent, contributing 0.18 percentage points to the total CPI 1-month change. The upward pressure came from garments.

Consumer Prices Index (CPI): Briefing on the change to the 12-month rate between July and August 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. This year the CPI rose by 0.5 per cent between July and August compared with a rise of 0.6 per cent between the same two months a year ago. The 1-month movement was therefore 0.1 percentage points lower this year and this led to the CPI 12-month rate falling from 2.6 per cent in July to 2.5 per cent in August 2012.

The most significant downward contributions to the change in the CPI 12-month rate between July and August 2012 came from:

  • furniture, household equipment & maintenance: prices, overall, rose by 0.8 per cent between July and August this year compared with a larger rise of 2.0 per cent between the same two months a year ago. This contributed -0.08 percentage points to the change in the CPI 12-month rate. The largest downward pressure came from furniture, furnishings & carpets (particularly from lounge furniture and tufted carpets) where prices, overall, rose by 0.9 per cent on the month, less than the 2.8 per cent rise a year ago. There was also a downward effect from non-durable household goods such as bleach and household cleaner cream.

  • housing & household services: prices, overall, rose by 0.1 per cent between July and August this year compared with a rise of 0.5 per cent a year ago. This contributed -0.05 percentage points to the change in the CPI 12-month rate. The main downward effects came from domestic gas and electricity where bills were unchanged overall this year but rose by 1.7 and 1.0 per cent respectively between July and August 2011. Regular maintenance & repair of the dwelling also contributed a small downward effect. These pressures were partially offset by a small upward effect from liquid fuels where prices, overall, rose by 7.1 per cent this year but fell by 3.7 per cent a year ago reflecting movements in oil prices.

  • clothing & footwear: prices, overall, rose by 2.8 per cent between July and August this year compared with a rise of 3.7 per cent a year ago. The 3.7 per cent was the largest rise between a July and August on record. These movements contributed -0.04 percentage points to the change in the CPI 12-month rate. The most significant downward effects came from menswear and, to a lesser extent, footwear. These were partially offset by a small upward pressure from womenswear.

  • restaurants & hotels: the main downward effect came from catering where prices rose this year by less than a year ago.

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

  • transport: prices, overall, rose by 1.3 per cent between July and August this year compared with a rise of 1.0 per cent a year ago. This contributed 0.06 percentage points to the change in the CPI 12-month rate. By far, the largest upward pressure came from motor fuels: petrol prices rose by 3.5 pence per litre between July and August this year compared with a more modest rise of 0.9 pence per litre a year ago. Similarly diesel prices rose by 3.3 pence per litre this year compared with 1.0 pence per litre a year ago. There was also a small upward effect from rail transport where prices were little changed this year but fell by 2.3 per cent a year ago. This was offset by a small downward effect from air transport where prices rose, as usual, between July and August but this year they rose by 10.2 per cent compared with 11.2 per cent in 2011. Flights to European destinations were the main contributor to this downward pressure.

  • alcohol & tobacco: prices, overall, rose by 0.2 per cent between July and August this year but fell by 0.6 per cent between the same two months a year ago. This contributed 0.03 percentage points to the change in the CPI 12-month rate. The effect came from spirits (particularly vodka and whisky) where prices rose by 2.3 per cent following sales in July this year but fell by 6.4 per cent when there were sales in August a year ago.

  • recreation & culture: the main upward effect came from games, toys & hobbies (particularly computer games and game consoles) where prices fell by 0.7 per cent this year compared with a larger fall of 2.6 per cent a year ago. This was partially offset by smaller downward effects from photographic equipment and recording media.

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

  • housing & household services: which contributed 0.7 percentage points, with the main upward effects coming from gas and rent, where charges, overall, rose by 13.4 per cent and 3.4 per cent respectively over the twelve months to August.

  • restaurants & hotels: which contributed 0.4 percentage points, with the main upward effect coming from catering where prices, overall, rose by 3.1 per cent over the year.

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 August, the CPIY rose by 2.4 per cent, down from 2.5 per cent in July. Therefore, the CPIY and CPI 12-month rates both fell by 0.1 percentage points between July and August. This is because 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 August, CPI-CT rose by 2.2 per cent, down from 2.3 per cent in July. Therefore, the CPI-CT and CPI 12-month rates both fell by 0.1 percentage points between July and August. This is because there were no changes to indirect taxation that impacted on the CPI between those months. TV licence fees and vehicle excise duty also had no effect on the change in the CPI 12-month rate.

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.

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 August, the all items RPI rose by 2.9 per cent, down from 3.2 per cent in July. The RPI 12-month rate has therefore decreased by 0.3 percentage points between July and August compared with a fall of 0.1 percentage points 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 larger fall in the RPI 12-month rate than the CPI 12-month rate between July and August is mainly due to:

  • other differences including weights: which increased the CPI 12-month rate relative to the RPI 12-month rate by 0.09 percentage points between July and August. The effect came mainly from motor fuels and insurance, partially offset by air fares.

  • rounding: this emphasises the downward movement in the RPI compared with the downward movement in the CPI.

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 August, the RPIX rose by 2.9 per cent, down from 3.2 per cent in July. Therefore, the RPIX and RPI 12-month rates both fell by 0.3 percentage points between July and August.

Mortgage interest payments had only a small upward impact on the change in the RPI 12-month rate between July and August. This impact was not sufficient to cause a difference between the changes to the RPIX and RPI 12-month rates between these two 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 August, the RPIY rose by 2.9 per cent, down from 3.2 per cent in July. Therefore, the RPIY and RPI 12-month rates both fell by 0.3 percentage points. This is because there were no changes to indirect taxation that impacted on the RPI between July and August. Mortgage interest payments also had only a small effect on the change to the RPI 12-month rate between the two months.

Data tables

CPI and RPI Reference Tables, August 2012: (1.27 Mb 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 & Table 4.1 in Focus is now the new Table 20.

Background notes

  1. Reflecting owner occupiers’ housing costs in a new additional measure of consumer price inflation

    At its 30 April 2012 meeting, the Consumer Prices Advisory Committee (CPAC) recommended the rental equivalence method for reflecting owner occupiers’ housing costs in a new additional measure of consumer price inflation. The subsequent public consultation closed on 31 August. A formal summary of response to the consultation will be published within the next three months.

  2. Next month

    Inflation for September 2011 to September 2012 will be published on 16 October 2012. CPI and RPI inflation rates between September 2011 and August 2012 were 1.8 per cent and 2.1 per cent respectively. Inflation rates for September 2011 to September 2012 will take account of price changes between August 2012 and September 2012.

  3. 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. The uprating is based on the 12-month change in the September CPI.

    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.

  4. 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. 

  5. 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.

  6. 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) .

  7. 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.

    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 per cent 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 the arithmetic mean to combine individual prices at the first stage of aggregation.

    • 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.  

  8. 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, we have taken the opportunity to make all CPI and RPI data available in one location. These CPI and RPI Reference Tables (1.27 Mb 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. Previously the data published covers January 1996 to March 2012. The data for April to June 2012 are also now available. 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 November CPI is published on 18 December 2012, at which point the detailed data published will be extended to September 2012.

    This bulletin includes the August 2012 data, collected on 14 August 2012. Future publication dates (43.6 Kb Pdf) for this Statistical Bulletin are available (now includes dates to January 2014). The Office for National Statistics (ONS) is proposing to push back the publication of its Producer Price Index Statistical Bulletin, following an internal quality assurance review. From the September 2012 data release, which will be published on 16 October, the Producer Price Index releases will be published at the same time as the Consumer Price Indices and House Price Indices.

    The European Commission (Eurostat) released figures for the harmonised index of consumer prices (HICP) for the month of August 2012 for EU Member States, together with an EU average, on 14 September 2012. Further information on HICP for the European Union, Eurozone and other EU Member States is available from Eurostat's HICP web page.  

  9. Further information

    A more detailed quality report (141.9 Kb Pdf) for this statistical bulletin is available. The report assesses the CPI and RPI against standard dimensions of quality such as relevance, accuracy and accessibility. The report was last updated in December 2011.

    The mini Triennial Review (1.75 Mb Pdf) of the CPI and RPI Central Collection of Prices is available.

    A full description of how the CPI and RPI are compiled is given in the Consumer Price Indices Technical Manual. (754.3 Kb Pdf)

    Further information on the CPI and RPI, including details of the methodology used to construct the indices, articles, historic data etc. is available on the Consumer Price Indices Taxonomy page.

  10. General

    Details of the policy governing the release of new data are available from the Media Relations Office. Also available is a list of the names of those given pre-release access (331.5 Kb Pdf) to the contents of this release.

    Bank and Treasury officials were informed at 5pm on the Friday before publication that an open letter was not needed this month between the Governor of the Bank of England and the Chancellor of the Exchequer.

    During 2010, an assessment team from the UK Statistics Authority conducted a review of the Office for National Statistics’ Consumer Price Indices. Their remit was to assess compliance with the Code of Practice for Official Statistics. In December 2010, the team published their conclusions as Assessment Report 79.

    While carrying out the assessment, the team also researched and published Monitoring Brief 7/2010 – Communicating Inflation.

    Following this assessment and ONS’s subsequent response, the UK Statistics Authority, on 31 January 2012 confirmed the designation of the CPI and RPI as National Statistics, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Official Statistics.

    Designation can be broadly interpreted to mean that the statistics:

    • meet identified user needs,

    • are well explained and readily accessible,

    • are produced according to sound methods,

    • are managed impartially and objectively in the public interest.

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