Immigration Health Surcharge

I read on Gov uk that a new immigration health surcharge [IHS] is payable by nearly all immigrants. It is £150 per year for students and £200 p.a. for the rest.

My brother is applying for his ILR on LR and soon getting married. Does his spouse has to pay for this charge, if yes how much?

I am aware there is a calculator on gov uk but the questions are very silly i.e. what the expiry date of ILR. On the RP card it is normally ten years but does this means that he has to pay £2200 for IHS?

The surcharge is not applicable to people applying for ILR.

It will need to be paid for the spouse though, payable upfront for the duration of the visa (e.g £200 x 2.5 year visa = £500)
