What Sans Serif font is this

I’m trying to copy this payslip example taken from disabilitytaxguide.org.uk. I have searched through about 200 Sans Serif fonts on Font Squirrel and also tried uploading the image on their website without success.

Why are you copying a payslip?

I have to design a payslip template for use in a small organisation (< 10 staff) and disabilitytaxguide.org.uk provide a free template example. I set the layout in Libreoffice Writer and happen to like this particular Sans Serif font.

It looks very like Calibri or Carlito apart from the square dot above the “i”.
