Immigration Health Surcharge (IHS)
From April 2015, when applying for a UK visa from abroad or when extending / switching to another category in the country, in addition to the visa fee, you must pay a fee for the right to use the British National Health Service. This applies to most immigration categories. Exceptions are visitor visas, visas for family members of EU nationals, and very few categories, such as family members of the UK’s armed forces.
You do not need to pay when applying for Settled Status under EU Settlement Scheme (Indefinite Leave to Remain).
You’ll have to pay:
£470 per year for a student or Youth Mobility Scheme visa, for example £940 for a 2-year visa
£470 per year for visa and immigration applicants who are under the age of 18 at time of application
£624 per year for all other visa and immigration applications, for example £3,120 for a 5-year visa
Dependants aged 18 or over usually need to pay the same amount as you.
If the application is submitted online then payment needs to be made at the time of the visa application. If your application is refused, IHS will be refunded in full.
