Following clarification from NHS Pensions, I would point out that this minimum uplift for members of the NHS Pension Scheme (as amended in 2008) applies only to Tier 2 provisions.
Tier 1 is to members deemed to be permanently incapable of doing their current NHS job. Tier 2 is for members who, in addition to this, are deemed permanently incapable of doing any other regular, appropriate employment given previous training and experience.
The uplift is subject to the maximum that the member could have had by normal retirement age (capped at age 60) and applies to 31 March 2016.
