The authority has confirmed that David Sidaway will take up his position on January 8, 2020.
The news comes after he was officially confirmed as the council’s chief executive following a unanimous vote by a meeting of full council on September 19.
Mr Sidaway is currently working a notice period with Stoke-on-Trent City Council.
A spokesman for Telford & Wrekin Council said: "David is already working closely with the council to ensure that he can have a smooth transition into the organisation in the New Year while he works out the notice at Stoke-on-Trent City Council."
Council interim chief officer Jonathan Rowe added: “We’re delighted to have a date for David’s return to Telford & Wrekin Council and are very grateful to Stoke for releasing David earlier than originally anticipated.”
