You may want to also consider private health insurance.
Many Brits still take out private healthcare insurance as there are additional benefits over Portugal state healthcare system, notably:
– You will get access to better facilities
– Reduced waiting times
– On-demand access to a network of private hospitals on top of Portugal’s state system
– Ongoing expenses, such as GP appointments and prescriptions will be covered
– Less language issues when receiving care
I hope this helps.
