Hello, I have just received the S1 forms from the UK now that I am officially a pensioner. The letter that came with them said "....from 6th April 2015 your right to return to England for all treatment including elective, has been extended. This means you can access NHS treatment in England as if ordinarily resident...this means treatment will be free unless a statutory charge applies e.g prescription charges. You will not need to obtain any kind of authorisation ...prior to seeking treatment"
Nice to know having paid my way for 40 years
Just makes life a bit more easy
