Volunary severance

we have a voluntary severance programme in which employees can volunteer to leave and be paid PILON and redundancy Can you please clarify for me: Is the PILON based on employer notice period /or employee notice period If employer notice period is this the statutory payment where contract may say more than this? eg if contract states 6 months employer notice, is the PILON based on the statutory 12 weeks ot the contractual 6 months?

Hi
PILON is based on the contracutal notice period.  
As PILON is being paid, you also need to do the Post Employment Notice Period (PENP) calculation.  
Guidance on this can be found at -
Post-employment notice pay (PENP) formula
Thankyou.
