UK residents who moved to the EU on or before 31 December 2020 whose healthcare costs are funded by the UK can get free NHS treatment in England, Scotland, and Wales. NHS charges must be paid where they apply to ordinary UK residents, for example prescription charges.
People who moved to the EU or Switzerland from 1 January 2021 are not automatically entitled to receive free NHS treatment when visiting England, Scotland, or Wales. This is because the NHS is a residence-based healthcare system.
S1 holders who need treatment in Northern Ireland must check their entitlement with the treatment facility in advance.
Accident and Emergency services and services that are deemed urgent or immediately necessary will always be provided free at the point of delivery first in the UK, with entitlement to NHS care determined afterwards.
