This Order makes consequential amendments to primary and secondary legislation as a result of the introduction on 12 October 2015 of Class 3A voluntary national insurance contributions. A person may pay a Class 3A contribution in return for a unit of additional pension which results in an increase in the weekly rate of the additional pension in a category A, B or D retirement pension. This was provided for by section 14A of the Social Security Contributions and Benefits Act 1992 which was inserted by paragraph 3 of Schedule 15 to the Pensions Act 2014.
