BRP renewal application fee

[tata2013]

Hi everyone,

My sister and I recently submitted the application form for renewing our ILR BRP and noticed that we paid different amount of fees. I have paid £75.20 whereas my sister has paid £56. So I was getting worried that one of us completed the wrong application. Does anyone know why this could be and whether we need to do something about it?

Many thanks in advance.

If I recall correctly the biometrics fee is £19.20 for any application so that seems to be the difference.
Why the difference? Perhaps someone else can explain.
