According to an email obtained by UTV, which was sent to all Policing Board members, David Cox will leave the HET on 28 September.
It reads: "The Chief Constable has confirmed this afternoon that both Dave Cox and Paul Johnston will leave their posts in the HET at the end of this month. The new leadership team, referred to at yesterday's Board meeting, take over on 28 September 2013."
However there is still confusion over the timing of Mr Cox's departure, and the PSNI could not confirm if he is leaving at the end of this month.
The move comes after a scathing report revealed HET investigations into army killings during the Troubles in Northern Ireland have been less rigorous.
Mr Cox had until now resisted demands from the Policing Board to step down immediately.
Chief Constable Matt Baggott insisted he would not be retiring until December - however that has now changed and it seems he is set to leave in a few weeks.
Board member Jonathan Craig said the move is a necessary one.
"There has obviously been a change of mind in the command team around the management of the HET," the DUP MLA told UTV.
"I think it is a step which will restore confidence in the HET so in that respect I welcome it.
"I do treat it with some sadness though because Mr Cox has served HET a long time. He has built it up from scratch."
Sinn Féin's Gerry Kelly said: "I'm glad that he's stepping down - the whole Policing Board was unanimous in saying that the leadership and management of the HET was completely out of order and it needed changed."
