Immigration Health Surcharge (IHS) is a fee that allows you to enjoy public medical services in the United Kingdom. If you are going to get a long-term visa, you will be charged an additional fee for medical services:
£470 per year – for applicants for a student visa;
£624 per year – for applicants for other visa types and their adult dependents;
£470 per year – for minors.
Note that you are expected to pay the whole sum for the validity period of your visa. For instance, a prospective holder of an Innovator visa is expected to pay £1,872 for 3 years.
This fee will allow you to get qualified medical help all over Great Britain but you’ll still need to pay for prescriptions, dental treatment, eye tests, pregnancy and assisted conception.
