"The BT scheme's other sections, "A" and "B", are for staff who joined the company after 1984. Those members are already on the Consumer Price Index (CPI) – which is usually around one percentage point higher than the RPI as an inflation measure."
CPI is usually about 1% lower than RPI. Currently RPI is 4.1%, CPI is 3.0% and CPIH is 2.7%.
