I was only in the UK for a couple of years, but they wrote to me at my Irish address asking if I wanted to pay a lump sum to keep up my contributions. I'm 35 and have never had an occupational pension. I did pay into a private one many years ago, probably for about 5 years at about £80 a month, which isn't much I know. I've no idea what the benefits are now. I have either not been working or have been paying very little tax for many years now so I didn't see the point in starting it up again. Now I'm wondering whether I should.
