If you're permanently moving abroad, an S1 form entitles you to the same state-provided healthcare cover as a citizen of that country.
European Union (EU) and Switzerland
An S1 form covers your healthcare in the EU country you move to.
Republic of Ireland
Although the Republic of Ireland is an EU country, you do not need an S1 form to access healthcare if you’re a UK citizen.
If you’re a UK citizen living in Ireland, you’re automatically entitled to state healthcare on the same basis as an Irish citizen. Read more on the GOV.UK website.
Norway, Iceland, Liechtenstein, and Switzerland
If you’ve moved to Norway, Iceland, Liechtenstein, and Switzerland before 1 January 2021, an S1 covers your healthcare.
If you moved to Norway, Iceland, Liechtenstein, and Switzerland after 1 January 2021 and are within the scope of the Withdrawal Agreement or a ‘Separation Agreement’ an S1 covers your healthcare.
A Separation Agreement applies when an individual has exercised their freedom of movement rights before 1 January 2021 or have paid contributions to the social security system within an EU country.
