Looking at the CPI list now, it appears that the weighting of housing is broken. It seems that rent is included whilst mortgage interest and imputed interest on equity is not. The split in the UK is very roughly 33% rental, 33% owned outright, 33% owner occupied. What that means is that essentially all the other items have roughly triple the weighting that they should - in a rough sense it ends up showing the housing costs of 1/3 of the population, whilst showing all other consumption of 100% of the population.
