Those who are moving abroad should purchase insurance in advance, from a business which is regulated by British consumer protection rules. They are rated amongst the most consumer-friendly in the world. If a dispute occurs, the UK Ombudsman mechanism is as likely to satisfy the policy holder as most regulators. However, once you have adjusted to your new country, it may be slightly cheaper to buy a local policy providing you haven’t developed a chronic condition. Portability of cover should not be overlooked. You should ensure your translation of any foreign language policy is correct. Remember, a good source of advice can come from members of the local expat community.
