2.4.1 EEA Retired Nationals
For the purposes of this section we define a 'retired person' as someone of the age of retirement of their country of origin, who exercises no professional activity, and who is in receipt of a State Pension from their home EEA country.
If you are an EEA national and in receipt of a State pension, or you suffer from long term incapacity, then in order to register with the French health system you will need to apply for a Form S1 certificate of entitlement from the social security authority in your country.
We also include in this category people under the age of retirement, but in receipt of long-term incapacity benefit.
UK nationals who relocated to France before January 2021 are entitled to an S1 when they reach State retirement age.
Those who hold an S1 certificate of exemption will only nominally be affiliated to the French health system (PUMA) for the purposes of administration, as European regulations grant them and their family members an entitlement to health cover via the certificate, paid for by their home country.
As a retired person, if you have an S1 you will continue to benefit indefinitely from free health insurance cover in France.
And allowed to access to NHS in UK.
