Moving to JA after Casual jobseekers

I have roughly 40 off days left on JSB (I am working 3 days pw for the last 3 months, prior to that I was getting 6 days JSB). I was advised to come up to the social office and apply for JSA. He said bring up a 'few' bank statement and proof of earnings but was vague to how many months or how many payslips.
Does anyone know? Its Tallaght office by the way.

I would phone back only its a nightmare to get through to them at the best of times.

Enough payslips to work out an average weekly pay for JA assessment and a year's bank statements should be plenty, if you have them. Because you were on JB the assessment for JA should not be too difficult. Bring what you have to hand.
