Stoop, I would agree with your assessment that in comparison with a person in their mid 20s that is what the premium is likely to be.
A comparison of premiums between travel insurance and PHI cannot really be made as they are two different products. To start with it is the time cover as travel insurance is generally a very limited period as PHI is yearly. The probability that a travel insurance company would be caught to cover the cost of any longterm illnesses like cancer would be near to zero.By the time the condition has been investigated the travel insurance will have expired. Insurance policies are in a way gambling. The bet is on probability and the older you are the more probable it is that you are going to get ill. Some banks give free travel insurance with current accounts as the profit generated from the extra business will more than cover the amounts to be paid out.There will always be the exception. When I worked in a financial institution the biggest pay out was nearly £100k. Most other claims were less than £200. The smallest claim was less than a quid. It must have cost more to report it.
