Quite a few years ago I was in a similar position as kev in regard to being made redundant part through the year, I then temped for a while and when I secured a permanent job, i stopped temping and had about a month or so off with the kids before starting my new job. I never signed on for that period as there was little point. It took about 3 years for me to get back my overpaid tax, particularly as I had no evidence - other than no money coming into my bank account and plenty going out! - that I hadn't been working - telling them I was living of my vast personal wealth didn't seem to help. Anyway, for me the process of getting the tax back was not automatic, I had to claim and it wasn't quick!! It didn't help that my new employers lost my p45 and I was on week 1 tax for a while until a p46 was sorted out.
