The costs vary considerably, depending on where you are moving and why. For example, family cover for a financial adviser moving to Germany will be cheaper than a skydiving instructor moving to central Africa. Averages are around £700 a year for an individual without any high-risk factors. You can buy insurance for £30, but it's unlikely to be sufficient if you do have any accidents or become unwell. Most policies have an excess of several hundred pounds and will have limits on how often you can use the insurance. If the value threshold is reached, cheap health cover may run out partway through a treatment or hospital admission. Therefore, it's crucial to choose a policy that provides safeguards, so you won't experience difficulties obtaining the treatment you need.
