For some UK expatriates, they may have, or be happy not to have, health insurance cover for both the UK and the country they live in. This may be particularly true in France or Spain. If a business has several such individuals who travel to other countries regularly on business, there is logic in setting up a special policy just for when they are away from either the UK or the country they now live in as an expatriate
Special short-term travel health insurances can cover emergency medical expenses when they are travelling.
