In OSR’s Regulatory Work Programme for 2019 to 2020 in respect to the economy theme,  among our priorities for the year is regulatory work on inflation statistics. We cited work arising from any change to the Authority’s approach to the RPI and to the measurement of Owner Occupiers’ Housing Costs within ONS’s CPIH statistics.  Following a request from the RPI/CPI user group that OSR consider the proposed changes to the RPI with respect to the Code of Practice for Statistics, the Chair of the UK Statistics Authority, Sir David Norgrove, wrote to the user group. OSR’s response to the concerns of the user group can be found here in the annex to Sir David Norgrove’s letter. OSR expects to publish the findings from its review of ONS’s recent work on CPIH statistics in March 2020.
