Thanks for the feedback - it has really helped me gather my thoughts.
I'm still not convinced that PHI makes sense for me because of the exclusion on Parkinson's. Thankfully, I don't have a family history of heart disease or stroke, which seem to result in a lot of people being forced to give up work early.
I wonder if there would be so much stress or bad backs if there people did not have PHI cover? I know the insurance companies vet claims carefully but stress is a grey area where it's hard to prove or disprove a claim. It's possible that stress could deteriorate rapidly if there was a chance it could provide a back door to early retirement. In any event, I'd hope to have the foresight to switch jobs long before stress got to the stage where I'd have to claim on PHI.
PHI cover is expensive - in my case €1,300 a year before tax relief. Yet it won't cover the one condition - Parkinson's - that worries me most. If I don't buy it, I still have social welfare as a safety net that can be topped up from savings.
As regards professional advice, I know from experience that nobody in their right mind will advise against PHI. The risks are just too great. What if I subsequently contracted a disease that forced me out of work? I would have a strong case against the broker who advised me.
