Going travelling- welfare on return?

The company I've worked for for 10 years shut its doors and I've been on JSB since. I finally received my redundancy and have decided to go travelling for a few months.... approx 4. People might think this a bit crazy when I'm not sure about my future, but I've worked hard for a long time and once I get my career back on track I may never get the chance to do this again.

Obviously I will have to sign off, but I'm wondering about my rights when I return? Can I sign back on without too much problems or will there be a lot of red tape and questions??
Any possibility I won't be able to sign back on?
Cheers
J

A few months won't pose a problem. Longer periods (over 6 months) may cause problems as they will use the habitual residence test to try to disqualify you from claiming.
