The State Second Pension or S2P was the additional state pension payable to people who reached State Pension Age before 6 April 2016. LGPS members were contracted out of S2P and paid a lower rate of National Insurance as a result.

Initially S2P was an earnings-related pension but from April 2009 it built up as a flat rate pension. It was replaced with the new single tier State Pension from 6 April 2016.
