Redundancy Termination Payments Payable When ?

[Bear]

I'm being made redundant this Friday after 9 years of service along with two other members of the team.

We have been told that we are getting our payout at the end of the month when they run the pay roll but looking on the Directgov website it says
http://www.direct.gov.uk/en/Employment/RedundancyAndLeavingYourJob/Redundancy/DG_182503

Leaving your job

On your last day at work you should receive all the wages you are entitled to, plus payment for any outstanding period of notice that you have not worked. You should receive:

• accrued holiday pay (payment for holiday owed which has not been taken)
• Income Tax form P45
• redundancy pay
• a letter stating the date of redundancy

I called ACAS about this and they said payments should be made on the day of your contract termination and any delay can only be made if there is agreement with the employer and employee.

Of course I can be patient and wait but why should I, if I should recieve payment upon termination of contract. So does anyone know if it is law that payment should be made upon termination of contract ?? Thanks.
