02/08/2018 - Annual inflation in the OECD area picked up to 2.8% in June 2018, compared with 2.6% in May. Energy prices increased by 10.4%, compared with 9.1% in the year to May, and food price inflation picked up to 1.8%, compared with 1.4% in May.

 Starting from the OECD CPI news release released in June 2018, the UK data published for the entire period by the OECD refers to the ONS lead inflation index, i.e. the Consumer Price Index Including Owner Occupiers’ Housing Costs (CPIH). This index is the most comprehensive measure of inflation in the UK. It extends the Consumer Price Index (CPI) formerly used by the OECD to include owner occupiers’ housing costs along with Council Tax.
