If you go abroad to live, then who looks after your health?
Since the NHS is a healthcare system that's based on the residence (ie the UK) of its users, this obviously means that when you no longer reside in the UK, you can no longer access its services.
For many who move abroad, the health system in the new country of residence is an important factor in terms of deciding what's required healthcare-wise. For instance, you may move to a country where there is an adequate state system that you have access to and can enrol it. But it may be that the system works significantly differently from the one at home - and often this is the case.
Quite often - even if you have the same access to a healthcare system as a national of that country, you'll still have to pay towards treaments and medicines.
On top of this, a lot of times there can be long waiting lists for various things. And additionally there's the language barrier too. All of which means that getting international cover is recommended and in the case of people working abroad on an international assignment it's often provided by their employer as part of the employment package. This is especially important if employees are being sent to work in areas where the facilities are basic.
If you're an employer it's worth checking out the different levels of international health cover that are available - it's possible to add optional cover compnents to suit the requirements of your employees and also your budget as an employer.
