Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what the average cost per call is of opening HMRC contact centres (a) Monday to Friday and (b) on a (i) Saturday and (ii) Sunday.
HMRC does not hold this information because they allocate staff resource in a flexible manner across a range of customer services and channels. This allows HMRC resource to be used more effectively and delivers better value for money.
