Bear in mind that SWA is also means-tested, and you won't qualify if your parnter/spouse is in full-time employment (if that's applicable in your case).
Many local offices advise persons waiting on JA/JB to go to the CWO, however they sometimes forget to tell them that SWA is means-tested (even if you're waiting on Jobseeker's Benefit which isn't means-tested).
And yes, the queues at CWO offices have also increased in recent months as they also deal with Rent Supplement, Mortgage Supplement and other emergency payments (and medical cards for areas outside Dublin as well).
