You can only contribute to a personal pension plan for 5 years and maximum 3,600 pounds per year for tax relief. You have to tell the provider you have moved overseas. Whether Class 2 NI are worth it does depend. If you are going overseas for a few years then prob not. If forever - like me then also not worth it. Also Brexit - if it ends up in a crash Brexit the pound will dive and inflation will rise asnd the economy tank. The UK government may even eventually not be able to pay pensions unless inflation takes care of the issue. Personally I just invest my money mostly in shares. Do note most UK brokers won't allow expats to deal in shares. You need an offshore account. Same with bank accounts and credit cards really. Some vanks are more flexible - by turning a blind eye. Don't forget you cant use tax free account products anymore. Buy to let is better imho if you plan to return. As that reduces the risk of runaway house prices - even if they dive you don't really lose out vs having stayed in UK. Also profits are likely to be low if starting now. I have property in my wife's country as that is where I will retire. And a farm. So I wont starve!
