As it says in the title; I have around 31 years State Pension payments (plus about 6 years part payments, which I believe count for nothing!). I want to ensure I pay up to the (currently) required 35 years before I get to 66 (I am just 61). Returning to UK end June to live - no more overseas work! What can I do to ensure my NI/State Pension payments continue up to the required 35 years? I believe there is a 'buy back' scheme which is expensive(?) I can register unemployed, so that the state pays the monthly amount - but I believe this is time consuming and I don't intend seeking work. Can I pay voluntarily from my pension income and if so,what class would it be and how much? Any information would be appreciated,particularly from anybody in a similar position.
