I have to pay for health insurance as a Netherlands resident, and my health insurance card doubles up as an EHIC card (literally, on the one side of it are the account details of my private account, on the other the regular EHIC stuff).
As far as I can see, this GHIC is just for UK residents.
Who can get a GHIC
Residents of the UK
Entitlement to a UK GHIC is not based on your nationality.
The UK operates a residency-based healthcare system (the NHS), which means access is generally determined by residency and not by the past or present payment of National Insurance contributions or UK taxes.
If you’re ordinarily resident in the UK and not insured by an EU country, Norway, Iceland, Liechtenstein or Switzerland, you’re likely to be considered insured by the UK and will be entitled to a GHIC.
You’ll need to provide the necessary evidence when applying.
There are certain circumstances where you may be entitled to a GHIC or UK-issued EHIC despite living in an EU country, Norway, Iceland, Liechtenstein or Switzerland.
You are not entitled to a GHIC if you’re insured by an EU country, Norway, Iceland, Liechtenstein or Switzerland but live in the UK. You should contact the relevant authority in the country you’re insured by and request an EHIC.
