CPIH
From ACT Wiki
UK
Consumer Prices Index including owner occupiers' housing costs.
This is a measure of consumer price inflation including owner occupiers’ housing costs (OOH) and is the most comprehensive measure of inflation.
CPIH is the leading price index for UK domestic consumption rather than the Consumer Prices Index (CPI).
The CPI inflation measure excludes owner occupiers' housing costs. CPIH was developed to help fill this gap.
