When all the referees that the BDO had used in recent years, resign together after the 2019 World Championship after a disagreement with the BDO, the organization has to put together a new group. Harry is one of the six new faces. Together with Josh Clough, Garin Roderick, John Fowler, Kerrie Crompton and MC Paul Booth, they are now in charge of the matches on the big stages.

Unfortunately for the six, the BDO ceases to exist after one season and only Gavin Roderick of the six is still active in the major WDF tournaments. 

First and only World Championship in 2020
