the irish pension does not kick in until 65/66 years so your mother has a while to go yet and there is no point in contacting them at this stage. Best to ring the Uk number given above and talk to them. AFAIK, you can buy contributions in order to get a pension entitlement (60 in GB, I think). I've heard the Geordies are very helpful ans nice people to talk to and know their stuff! Well worth a phone call!
