When I reach 66 in 2035 I will only be entitled to approx. 86% of Irish State Pension (forecast to have a total of 1797 combined reckonable contributions). Reason I'm short 300 odd is that I lived in UK for 11 years and paid no Irish contributions in this time (1989-2000). I will be shy about 5/6 years of contributions. My question is - can I buy back the shortfall? Apologies if this has already been asked..... Many thanks.
