State Earnings Related Pension Scheme (SERPS)
This is the extra earnings related part of the state pension that employed people could earn up to 5 April 2002. LGPS members were automatically contracted out of SERPS, and most paid lower national insurance contributions as a result.
SERPS was replaced by the State Second Pension (S2P) from 6 April 2002 which, in turn, was replaced by the single tier State Pension from
6 April 2016.
