Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what assessment his Department has made of the potential cost of updating the incoming Customs Declaration Service in order to cope with customs declarations once the UK leaves the EU customs union.

The new Customs Declarations Service is designed to accommodate increased volumes in customs declarations, including any arising as a consequence of the UK’s departure from the European Union. HM Revenue and Customs continues to monitor the position.
