Your employer has a duty to pay you your redundancy payment on your final day of employment. By law you should receive a statement that details how your payment was calculated.
You and your employer can also agree a payment date soon after your final day of employment, if you wish.
If you feel that your employer has miscalculated your redundancy pay or hasn’t paid you correctly during your notice, you may wish to raise this with them. It may be an innocent oversight that can be corrected, or if they refuse to pay you what you’re owed, you may wish to take legal action.
