PenXchange was introduced for PensionBuilderplus with effect from 1 April 2007.

PenXchange provides National Insurance (NI) savings for both employees and Lafarge. PenXchange is a voluntary arrangement that all members of PensionBuilderplus will participate in, but some may wish to opt out.

How does it work?

In a nutshell there are 4 steps:

  • You stop making pension contributions
  • Your contractual gross pay is reduced by an amount equal to your PensionBuilderplus contributions
  • Lafarge pays an additional amount into your PensionBuilderplus personal investment account equal to your contributions to make up the difference
  • You pay less National Insurance so your take home pay will increase

Let’s give you an example of a member earning £22,000 basic pay with an annual contribution of about £1,000 to PensionBuilderplus using the same 4 steps.


You stop making pension contributions of £1000.



Your contractual gross pay will reduce by the £1000 that you would otherwise contribute into the PensionBuilderplus.



Lafarge will pay an extra £1000 into your PensionBuilderplus investment account to make up the difference.



You’ll pay around £120 less NI for the year and the £1,000 will go into your PensionBuilderplus investment account *


 * This example is based on NI contribution rates applicable in the 2015/2016 tax year
