Unrevised UK House Price Index arithmetic mean use in the RPI House Depreciation Index

You asked

Please provide a historical time series from February 2017 in electronic format of the unrevised "UK House Price Index - arithmetic mean for Great Britain" which was used each month in the calculation of the Retail Price Index Depreciation index with ONS Series ID CHOO. Whilst there have been various releases of an arithmetic mean series, the most recent of which was on the 27 May 2020, those feature revised values for prior months and so do not reflect the actual time series used in the calculation of the depreciation index.
