Taken form CAB website:
Redundancy pay does not affect contribution-based JSA. However, if you get redundancy pay in excess of the statutory amount, you may not get contribution-based JSA for the period treated as covered by the extra payment. If you received holiday pay as part of your final wage, you cannot get contribution-based JSA for up to four weeks after your job ends.
So basically if you get too much in redundancy pay out you will not be entitled to income based JSA. Oh that was in response to Pelvic floor by the way.
BeMyLB- Contribution-based JSA:
This is a non-means-tested benefit, so it is not affected by the amount of savings that you have, redundancy settlements or your partner's earnings. If there is other income, for example, part-time work while signing-on for JSA, or income from occupational or personal pensions and this income exceeds a certain limit, deductions will be made from the JSA.
This benefit depends upon certain National Insurance contribution conditions being met together with job-seeking rules (Who is eligible to claim JSA).
Contribution-based JSA is only paid for six months and no additional claims can be made for partners or dependant children on this benefit. Contribution-based Jobseeker?s Allowance is a personal allowance that is based on the National Insurance contributions you have paid over two tax years. We can pay this for up to 182 days.
This is just advice. Please always check with Benefits office.
