I purchased my holiday insurance for a very reasonable premium 13 days to the Canaries £66.00 , I am over 80 and am lucky to have good health so this did make things easier. However they have a huge list of illnesses that are exempt and which you dont have to declare . Illnesses that are not on this list are not covered . This may be a problem for some but I suggest it is really worth having a look at their website. www.ehicexpand.com . The insurer is Mapire Assistance. They also do Annual insurance for up to 85.
