You are correct, the pension is no longer linked to RPI but rather CPI. The % is taken from each past year in which the pension has been paid. You get the benefit of the rolled up effect together with whatever commutation ammount you took when you are age 55. Until then you will continue to receive your pension at its current value. Hope that helps.
