Additional State Pension (ASP)
This is paid in addition to the BSP.
Until April 2002, it was known as SERPS and depended solely on the National Insurance Contributions (NICs) paid as an employee.
From 6 April 2002, SERPS was reformed to provide a more generous ASP for low and moderate earners, carers and people with a long-term illness or disability. The reformed ASP, is based upon earnings on which standard rate Class 1 NICs are paid or treated as having been paid. This means that the ASP is an earnings-related pension.
