What is the health surcharge?
The Home Office have introduced an Immigration Health Surcharge which must be paid in addition to the application fee for Tier 4 students and their dependants.
If you're applying from outside the UK you're not required to pay the Health Surcharge if the length of your visa will be six months or less. If you're applying within the UK you'll be required to pay the Health Surcharge regardless of how long you're applying for your extension for.
If you have your own private medical insurance you must still pay the surcharge, even if you don't intend to use the National Health Service (NHS).
Paying the surcharge
You'll be prompted to pay the Immigration Health Surcharge after submitting your Tier 4 visa application. If you submit your visa application from within the UK with the assistance of the International Student Support Team, an adviser will assist you in making the Immigration Health Surcharge online payment.
