As part of these arrangements, we publish both the Retail Prices Index (RPI) and the percentage change in the weighted average of the relevant gas (wSSP) each year in time for changes to take effect from 1 January of the following year.
This letter specifies the wSSP for year and RPI for 2016:
The underlying calculations are described in appendix 1 of the letter.
