if he is suffering from various aches and pains over the past few months, then if he has not informed teh company of that when taking out the policy, and by telling the company, i mean writing it on the propoeal form, not having a general chat with the seller, he may not be covered in the event of a claim!
this appears to be a personal accident poicy, which would have various terms and conditions. It is not the same as VHI or BUPA. As far as i know, the 'health insurance' mentioned may only be a hospital cash benefit, which would pay a fixed sum per day for every day he was in hospital, after a minimum period. It is not the same as health insurance.
