We are of Welsh origin and lived in Africa for over 22 years...my sensible father paid back his national Insurance contribution in yearly clumps as well as paying back his stamp duty as he was concerned that he would be able to claim a pension as a Brit when he retired.....
He has since returned to the UK and he is no better off...his financial advisor told him that he should have just relied on the basic state pension as that is sufficient and that his £35 000 he had paid over 22 years was money down the drain....

What you might want to do is what Im doing...apply for a private pension....I pay approx £22.50 a week for mine and it covers me sufficiently. When I retire I will also have my state pension as well as any other prearranged pension....ie. teachers pension.....This should entititle me to around £1800 in today's terms as predicted by a financial advisor...another way forward is to invest in property in the UK...At the moment it is booming and it wont come to rest as long as the Olympics is happening in 2012...get a cheap property and do it up and you will rake it when you sell it closer to the time of the Olympics... if these all fail.....I suggest you play the Lottery!!!!!

Good Luck
