So, just to give you an update, my dad went to the solicitor today. My mum waited in the waiting room and after 15 mins, she was called in. Turns out my dad hadn't mentioned POA at all (he'd forgotten) and had just been talking about his will (which is all sorted and has been for ages). So, my mum explained the situation and the very nice solicitor explained very clearly and simply, why it might be a good idea to have a POA. My dad seemed to understand and agree (first question was 'how much is it going to cost?') and he's got 2 weeks to think about it now. Another meeting has been arranged for the beginning of May. Feels like some progress has been made. Thanks for all your advice.
