Services producer price inflation, UK: April to June 2019

• The annual rate of growth for the Services Producer Price Index (SPPI) was 1.6% in Quarter 2 (Apr to June) 2019, down from 1.7% in Quarter 1 (Jan to Mar) 2019.

• The price of services sold by UK companies slowed to 0.3% in Quarter 2 2019, down from 0.5% in Quarter 1 2019.

• Transportation and storage provided the largest upward contribution to the annual rate, and information and communication provided the largest upward contribution to the quarterly rate.

The SPPI provides a measure of inflation for the UK services sector. It is constructed from a statutory quarterly survey, which measures changes in the price of services provided to UK-based customers for a range of industries. Individual SPPIs are available, which provide information on price change for a selection of services industries. These individual price indices are also aggregated together to create a services industry SPPI with limited coverage (it does not provide full coverage of the “services sector”).

The services sector is estimated to account for around 80% of the UK economy based on its weight in gross domestic product (GDP). We do not produce an index for every industry in the services sector and so the SPPI is a partial, best, estimate of the overall inflation to UK businesses in the services sector. The SPPIs presented in this statistical bulletin are estimated to represent 59% of the total services sector at industry level. The SPPI's coverage of the services sector at Standard Industrial Classification (SIC) class, division and section level is available in the SPPI user guidance and methodology article.

As resources allow, we will continue to review the existing indices and expand coverage through developing indices for new industries. As such, the SPPI will change composition from time to time but will always remain our best estimate of inflation in the UK services sector. You should consider that coverage may change over time when deciding which indices best meet your needs.

The figures presented in this statistical bulletin are considered provisional for the latest two quarters and may be revised as late data are received.

All figures presented in this statistical bulletin are calculated on a gross sector basis unless otherwise stated and all index numbers exclude Value Added Tax (VAT). None of the indices presented in this bulletin are seasonally adjusted.

Every five years, SPPIs are rebased and their weights updated to reflect changes in industry.

The Services Producer Price Index (SPPI) has reported positive growth for most of the period across the past 10 years (Figure 1). SPPI annual growth slowed from 0.5% in Quarter 1 (Jan to Mar) 2009 to a negative 1.3% in Quarter 2 (Apr to June) 2009, before returning to more typical growth from early 2010. The annual inflation rate was 1.6% in Quarter 2 2019, down from 1.7% in Quarter 1 2019.

The Services Producer Price Index (SPPI) slowed to 1.6% on the year to Quarter 2 (Apr to June) 2019, down from 1.7% on the year to Quarter 1 (Jan to Mar) 2019. The price of services sold by UK companies rose by 0.3% between Quarter 1 2019 and Quarter 2 2019.

The annual rate has remained positive since Quarter 1 2010, whilst the quarterly rate has remained positive for 10 consecutive quarters.

Of the 10 sections (as defined by the Standard Industrial Classification 2007: SIC 2007) that are combined to form the Services Producer Price Index (SPPI), nine showed annual price increases. Only prices for water supply, sewerage and waste management displayed negative annual price inflation.

On a quarterly basis, eight sections showed upward contributions to the quarterly rate, only prices for professional, scientific and technical activities, and transportation and storage showed negative price inflation.

Other services showed the largest price increase on the year to Quarter 2 (Apr to June) 2019 at 3.5%, the highest positive growth we have seen in this index (Table 2). This was driven by commercial washing and dry cleaning – hire and rental, which rose 3.5% on the year in Quarter 2 2019.

Transportation and storage provided the largest upward contribution to the annual rate for the fourth consecutive quarter, contributing 0.58 percentage points (Figure 2) in Quarter 2 2019. Prices for transportation and storage rose 2.9% over the year (Table 2), driven by business air fares whose prices were up 5.5% on the year, but slowed from 5.6% in Quarter 1 (Jan to Mar) 2019.

Information and communication provided the second-largest upward contribution to the annual rate, contributing 0.46 percentage points. The 12-month rate was 2.2% in Quarter 2 2019, which was the same in Quarter 1 2019. Computer software services was the main contributor to the rate with prices rising 2.1% on the year, up from 1.6% in Quarter 1 2019. This is the highest positive annual growth we have seen in computer services since Quarter 4 (Oct to Dec) 2006.

Water supply, sewerage and waste management provided the only downward contribution to the annual rate, at negative 0.03 percentage points (Figure 2). Prices within the industry showed negative growth of 2.0% on the year. The main driver to the decrease was sorted materials recovery services where prices were negative 9.6% on the year, this was up from negative 11.2% on the year from Quarter 1 2019.

Seven industries displayed positive contributions to the quarterly price increase of 0.3%. Information and communication was the main contributor to the quarterly rate, at 0.23 percentage points (Figure 2). Prices within the industry slowed to 0.7% between Quarter 1 2019 and Quarter 2 2019, driven mainly by prices for computer software, which slowed to 0.9% on the quarter.

Professional, scientific and technical activities provided the largest downward contribution to the quarterly rate, with a contribution of negative 0.21 percentage points (Figure 2), this was driven mainly by business and management consultancy where prices fell 3.5% on the quarter.

In addition to the data included within this statistical bulletin, the following detailed datasets are available.

Details of when the annual and monthly inflation rates were previously higher than, lower than, or at the same rate as the current quarter are shown in the Services producer price inflation (SPPI) records.

A summary of the revisions to SPPI data is available in the SPPI revision triangles.

Other important measures of inflation and prices include the Consumer Prices Index (CPI) and the Producer Price Index (PPI).

The Consumer Price Index estimates the rate at which the price of goods or services bought by households rise or fall using price indices.

The Producer Price Index measures changes in the prices of goods bought and sold by UK manufacturers, including price indices of materials and fuels purchased (input prices) and factory gate prices (output prices).

The Services Producer Price Indices (SPPI) Quality and Methodology information report contains important information on:

• the strengths and limitations of the data and how it compares with related data
• uses and users of the data
• how the output was created
• the quality of the output including the accuracy of the data

If you would like more information about the reliability of the data, the latest SPPI standard errors were published on 4 December 2017. The article presents calculated standard errors for the period between Quarter 1 (Jan to Mar) 2016 and Quarter 3 (July to Sept) 2017, for both quarter-on-quarter and 12-month growth. A previous SPPI standard errors article presents the calculated standard errors for the period Quarter 2 (Apr to June) 2012 to Quarter 1 (Jan to Mar) 2016.

Guidance on using indices in indexation clauses (2015) has been published. It covers producer prices, services producer prices and consumer prices.

Detailed information on the methods used to compile the SPPI is available in the SPPI manual.
