If I accept the voluntary redundancy with a date of leaving in 3 months time, can I pay anything now into the Scheme to increase my benefits?

You will not be able to make regular Additional Pension Contributions to the Scheme to purchase additional pension, as the minimum term permitted is one year.  However, you could make a lump sum payment. 

In addition, you may be able to make Additional Voluntary Contributions through our current AVC provider, Prudential, provided that the contributions are made through your payroll and do not exceed your pay less employer deductions.
