Moving abroad is such a major step that it is essential that you have information about some very key issues:
Firstly, if you are moving to the EU then, if you are a UK citizen then you have a right to live in any other European Economic Area country. For any country outside this area it is important to look at the website of the British Embassy for that country to check for information.
Secondly, you need to be clear about your UK tax, pensions and benefits situation. You can get an estimate of you UK State Pension. In addition you will need to check with HM Revenue and Customs about your tax liability on income above your personal allowance.
Thirdly, it is essential that you sort out your healthcare situation in the country you are moving to and find out about healthcare costs. Some UK welfare benefits are not payable outside the UK, and others apply only in the EU or countries that have reciprocal agreements. Check to see if medical insurance would be necessary to cover private medical and dental treatment- and cover for returning you to the UK in cases of medical emergency.
Finally, there is a long list of things to consider on the government website for those moving abroad that is worth checking. These refer to essentials such as residence permits, passport validity, opening a bank account, checking local traffic regulations and driving licence needs as well as making a will.
