Comparing UK Inflation Measures
Compare the main UK annual inflation measures. All three show the percentage change in prices over 12 months.
Producer Prices (Factory-Gate Inflation)
Producer prices sit upstream of the shops. Input prices are what manufacturers pay for materials and fuels; output prices are what they charge at the factory gate. Both are measured on the same Index (2015 = 100), so they can be compared directly — and rising producer costs often feed through to consumer prices months later.
UK producer input prices (materials and fuels bought by manufacturers) versus output prices (factory-gate prices charged), both Index 2015=100, monthly. Shown on a shared axis without rebasing. ONS.
Materials and fuels purchased by UK manufacturers, Index 2015=100, monthly. A leading signal for consumer inflation. ONS PPI (GHIP).
Factory-gate prices charged by UK manufacturers (excluding duty), Index 2015=100, monthly. ONS PPI (GB7S).
CPI is the main measure used for the Bank of England's 2% inflation target and international comparisons. It tracks the cost of a representative basket of goods and services purchased by UK households.
CPIH includes owner occupiers' housing costs and is ONS's lead consumer price inflation measure. It provides a more comprehensive view of household costs by including the costs associated with owning a home.
RPI is an older legacy measure. It is still published and used in some contracts (including some index-linked gilts and rail fare increases), but it is not an Accredited Official Statistic and should be treated carefully.
The inflation rate shows how quickly prices are rising compared with a year earlier (expressed as a percentage). A price index shows the cumulative price level relative to a base year (e.g. 2015=100).
