Mobile homes pitch fees - annual uprating index: consultation

Weaknesses of the current RPI index

13. RPI lost its status as a National Statistic in 2013. While RPI is still reported, the Office for National Statistics (ONS) now discourage the use of RPI and consider it to be a poor measure of general inflation, at times greatly overestimating and at other times underestimating changes in prices and how price changes are experienced due to methodological issues. Despite this, for historical reasons it is still used across parts of government. The UK Government has confirmed that it will reform the measure of RPI from 2030, aligning the methodology with CPIH.^[1] It is only legally possible to do this from 2030 due to the maturity of the final specific index-linked gilt. For these reasons, we do not think that RPI is an appropriate basis for uprating pitch fees.
