Key points

  • CPI annual inflation stands at 3.0 per cent in April 2012.
  • RPI annual inflation stands at 3.5 per cent in April 2012.

Headlines for the April 2012 Consumer Price Indices

  • CPI annual inflation stands at 3.0 per cent in April 2012, down from 3.5 per cent in March.

    The timing of Easter had a significant impact on the April data (see background note 1). The annual rate was last lower in December 2009 when it was 2.9 per cent although the 3.0 per cent was equalled in February 2010. The CPI stands at 122.9 in April 2012 based on 2005=100.

  • Air transport, off-sales of alcohol, clothing and sea transport were the most significant drivers behind the decrease in annual inflation between March and April.

  • The largest upward pressures to the change in CPI annual inflation between March and April came from the operation of personal transport equipment, restaurants & hotels and rents.

  • RPI annual inflation stands at 3.5 per cent in April, down from 3.6 per cent in March.

    The annual rate was last lower in December 2009. The largest downward pressures to the change in RPI annual inflation between March and April came from alcoholic drinks, clothing, fares & other travel and the purchase of motor vehicles. Partially offsetting these were upward pressures from housing and petrol & oil. The RPI stands at 242.5 in April 2012 based on January 1987=100.

Download chart

The CPI rose by 0.6 per cent between March and April this year compared with a rise of 1.0 per cent a year ago. The rise this year is within the normal range for a March to April movement but the 1.0 per cent rise in 2011 is a record increase for a March to April period. Between 1996 and 2010, the 1-month change between March and April has varied between increases of 0.2 per cent and 0.8 per cent.

The most significant upward contributions to the 1-month change in the CPI between March and April 2012 came from:

  • transport: prices, overall, rose by 1.2 per cent. The largest upward effect came from a 2.0 per cent increase in the price of fuels & lubricants. Petrol prices rose by 3.2 pence per litre on the month to reach a record £1.42 per litre. Diesel prices rose by 2.1 pence per litre to also reach a record level of around £1.48 per litre. There was also a large upward effect from air transport where fares rose by 7.4 per cent between March and April.

  • housing & household services: prices, overall, rose by 0.9 per cent between March and April. The upward effects came from actual rentals for housing and water supply & miscellaneous services for the dwelling.

  • alcoholic beverages & tobacco: the increase in excise duties that came into force towards the end of March 2012 contributed to prices rising by 2.9 per cent overall. The upward effect came from tobacco where prices rose by 5.1 per cent.

  • restaurants & hotels: prices, overall, rose by 1.0 per cent between March and April with the largest effect coming from restaurants and cafes.

The most significant downward contribution to the 1-month change in the CPI between March and April 2012 came from:

  • furniture, household equipment & maintenance: prices, overall, fell by 1.2 per cent. The largest downward effect came from furniture and furnishings.

(total CPI -0.5 percentage points)

This chart shows the contributions to the 12 month rate.

Download chart

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 0.6 per cent between March and April compared with a rise of 1.0 per cent between the same two months a year ago. The 1-month movement was therefore 0.4 percentage points lower this year and this led to the CPI 12-month rate falling from 3.5 per cent in March to 3.0 per cent in April 2012. The 0.1 percentage point difference is due to rounding.

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

  • transport: prices, overall, rose by 1.2 per cent between March and April this year compared with a rise of 2.8 per cent between the same two months a year ago. By far the largest downward effect came from air transport where the timing of Easter contributed to fares rising by 7.4 per cent this year compared with 29.0 per cent a year ago. There was also a large downward effect from sea transport where, again, the timing of Easter was a factor: fares rose by 4.2 per cent between March and April 2012 compared with a rise of 22.3 per cent between the same two months in 2011. A smaller downward effect came from second-hand cars where prices rose by less than a year ago. Partially offsetting these downward effects was a small upward contribution from fuels & lubricants where prices rose by more than a year ago. A factor in this was the decrease in duty that influenced fuel prices in April 2011.

  • alcoholic beverages & tobacco: prices, overall, rose by 2.9 per cent between March and April 2012 compared with a record 5.3 per cent in 2011. The increase in excise duties on alcohol and tobacco that came into force towards the end of March 2012 had a less significant impact on the April 2012 CPI than the increase in duties introduced in March 2011 had on the April 2011 CPI. There was also a downward contribution from the price discounting of some products in April 2012, particularly vodka and beer.

  • clothing & footwear: prices, overall, rose by 0.2 per cent between March and April this year compared with a rise of 1.3 per cent between the same two months a year ago. The downward effect came principally from garments, particularly women’s outerwear.

  • food & non-alcoholic beverages: prices, overall, fell by 0.1 per cent between March and April this year compared with a rise of 0.1 per cent between the same two months a year ago. The main downward effects came from vegetables (particularly potato products), bread & cereals and meat. Partially offsetting upward effects came from fruit and sugar, jam, syrups, chocolate & confectionery.

  • furniture, household equipment & maintenance: the largest downward effects came from furniture & furnishings and household textiles partially offset by an upward contribution from carpets & other floor coverings. 

  • communication: the downward effect came from postal charges which were unchanged this year but rose by a record 10.5 per cent between March and April 2011.

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

  • restaurants & hotels: prices, overall, rose by 1.0 per cent between March and April this year compared with a rise of 0.6 per cent a year ago. The upward effect came from accommodation services.

  • recreation & culture: the upward effects were from a variety of product groups with the most significant being games, toys & hobbies (particularly computer games) and package holidays. These were partially offset by a variety of downward effects, principally from cultural services and photographic, cinematographic & optical equipment where prices fell by 0.8 per cent in 2012 but rose by 4.1 per cent in 2011.

  • housing & household services: prices, overall, rose by 0.9 per cent between March and April this year compared with 0.8 per cent between the same two months a year ago. The upward effect was driven by rents with a partially offsetting downward effect from gas where average bills fell this year but were unchanged a year ago.

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

  • housing & household services which contributed 0.8 percentage points with the main upward effects coming from gas, electricity and rent, where charges, overall, rose by 15.4 per cent, 8.1 per cent and 3.4 per cent respectively over the 12 months to April,

  • food & non-alcoholic beverages which contributed 0.5 percentage points with prices, overall, rising by 4.3 per cent over the year. The upward contributions were widespread with all categories having upward effects; the largest came from meat, where prices rose by 5.1 per cent over the 12 months to April, fruit, where there was a 3.8 per cent rise, and sugar, jam, syrups, chocolate & confectionery, with a 5.2 per cent rise,

  • restaurants & hotels which contributed 0.4 percentage points with the main upward effect coming from restaurants & cafes,

  • transport which contributed 0.3 percentage points. The largest upward effect came from fuels & lubricants, where prices, overall, rose by 5.3 per cent over the 12 months to April. This was partially offset by a downward pull from second-hand cars where prices fell by 5.7 per cent over the same period,

  • miscellaneous goods & services which also contributed 0.3 percentage points. The upward effects were widespread with the most significant coming from jewellery, clocks & watches. 

Other measures of CPI inflation

 

Percentage changes over 12 months

This chart provides a comparison between CPI, CPIY and CPI-CT between April 2010 and April 2012.

Download chart

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 April, the CPIY rose by 3.0 per cent, down from 3.5 per cent in March. The CPIY and CPI 12-month rates have therefore both decreased by 0.5 percentage points between March and April. The difference between the changes in duty that came into effect in April 2012 compared with the equivalent changes in April 2011 was not sufficient to cause a divergence between the changes in the CPIY and CPI 12-month rates between March and April. In part, this is because the impact of the duty changes was offset by rounding in the CPI and CPIY rates.

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 April, CPI-CT rose by 2.8 per cent, down from 3.3 per cent in March. The CPI-CT and CPI 12-month rates have therefore both decreased by 0.5 percentage points between March and April. The difference between the changes in duty that came into effect in April 2012 compared with the equivalent changes in April 2011 was not sufficient to cause a divergence between the changes in the CPI-CT and CPI 12-month rates between March and April. This is because the impact of the duty changes was offset by rounding in the CPI and CPI-CT rates.

All items Retail Prices Index (RPI)

In the year to April the all items RPI rose by 3.5 per cent, down from 3.6 per cent in March. The RPI 12-month rate has therefore decreased by 0.1 percentage points between March and April compared with a fall of 0.5 percentage points in the CPI 12-month rate between the same two months.

The smaller fall in the RPI 12-month rate than the CPI 12-month rate is mainly due to:

  • air transport: has a lower weight in the RPI than the CPI so the downward effect from this component had a smaller impact on the RPI,

  • sea transport: has a lower weight in the RPI than the CPI so the downward effect from this component had a smaller impact on the RPI,

  • fuels & lubricants : prices are collected in the middle of the month for the RPI but are averaged across the month for the CPI. This resulted in a larger upward effect on the RPI than the CPI,

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

This chart provides a comparison between RPI, RPIY and RPIX between April 2010 and April 2012.

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 is excluded from RPIX.

In the year to April, the RPIX rose by 3.5 per cent, down from 3.7 per cent in March. Therefore the RPIX 12-month rate fell by 0.2 percentage points between March and April compared with a decrease of 0.1 percentage points in the RPI 12-month rate between the same two months.

The impact of rounding is the reason for the small difference between the changes in the RPIX and RPI 12-month rates. Mortgage interest payments had only a negligible effect on the change in the RPI 12-month rate between March and April.

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 April, the RPIY rose by 3.6 per cent, down from 3.9 per cent in March. Therefore the RPIY 12-month rate fell by 0.3 percentage points between March and April compared with a decrease of 0.1 percentage points in the RPI 12-month rate between the same two months. The larger fall in the RPIY 12-month rate than the RPI 12-month rate is mainly due to:  

  • petrol & oil: had a smaller upward effect on RPIY than RPI. This is because the decrease in road fuel duty that influenced fuel prices in April 2011 and effectively added to the rise in the RPI 12-month rate in April 2012 did not impact on the RPIY, 

  • fares & other travel: had a larger downward effect on RPIY than RPI. The increase in air passenger duty in April 2012 did not impact on the RPIY but did affect the RPI,  

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

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. Impact of the timing of Easter on the April 2012 CPI and RPI

    The timing of Easter in 2011 and 2012 had a significant impact on certain travel costs included in the CPI and RPI. This is due to the collection methods used to measure air transport and sea transport. Overall, these forms of transport reduced CPI and RPI annual inflation in April 2012 by 0.27 percentage points.

    For air transport, prices are collected for long haul, European and domestic flights. Fares are collected at various points in advance of the departure date, which for the April 2011 CPI and RPI was the 12 April 2011 with the return dates three weeks later for long haul flights, two weeks for European routes and one week for domestic flights. Easter Sunday in 2011 fell on the 24 April which meant that most of the return trips fell in or just after the school holiday periods in England and Wales.

    Prices were collected for domestic and international sea transport at various points in advance of the 2011 departure date of the 12 April with the return dates the following Sunday. This meant that the return legs fell in the school holiday periods in England and Wales.

    Easter Sunday in 2012 fell on 8 April so missed the collection period for air and sea transport in the April 2012 CPI and RPI completely.

  2. Public consultation on the recommended method of reflecting owner occupiers' housing costs in a new additional measure of consumer price inflation and ONS's strategy for consumer price statistics

    On 11 June 2012, ONS will launch a public consultation on the recommended method of reflecting owner occupiers' housing (OOH) costs in a new additional measure of consumer price inflation and its strategy for consumer price statistics.  Following the recommendation by the Consumer Prices Advisory Committee (CPAC) at its 30 April 2012 (1.59 Mb ZIP) meeting ONS is inviting views on using the rental equivalence approach as the preferred method of reflecting owner occupiers' housing costs and would also welcome users' comments on its strategy for consumer price statistics.  Further information on the consultation and how to respond will be published on 11 June 2012.

  3. CPI and RPI Weights

    In line with usual practice the CPI and RPI weights were updated with the publication of the January and February datasets. Additional details of the update are available from the ONS in an article published on 24 April entitled Consumer Prices Index and Retail Prices Index: Updating Weights for 2012.

  4. Next month

    Inflation for May 2011 to May 2012 will be published on 19 June 2012. CPI and RPI inflation rates between May 2011 and April 2012 were 2.8 per cent and 3.1 per cent respectively. Inflation rates for May 2011 to May 2012 will take account of price changes between April 2012 and May 2012. 

  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. From April 2011 the CPI is also being 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.

  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 ONS 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.

    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.

    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.

  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 . 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 from April 2011 the CPI is being 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 annual inflation rates.

    Also available is an explanation of the increased impact that the different formula used to construct the CPI and RPI 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 ONS 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 Detailed 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. The data published covers January 1996 to December 2011. 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 May CPI is published on 19 June 2012, at which point the detailed data published will be extended to March 2012.

    This bulletin includes the April 2012 data, collected on 17 April 2012. Future publication dates (16.9 Kb Pdf) for this Statistical Bulletin are available. The European Commission (Eurostat) released figures for the harmonised index of consumer prices (HICP) for the month of April 2012 for EU Member States, together with an EU average, on 16 May 2012.

    ONS has recently published commentary, analysis and policy on ‘Special events’ which may affect statistical outputs. For full details go to the Special events page on the ONS website.

    During 2010, an assessment team from the UK Statistics Authority conducted a review of the Office for National Statistics's 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, and

    • 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.
