Savills said that chief executive Jeremy Helsby would retire at the end of 2018, after 11 years at the helm, as it upgraded its profit guidance.
The real estate group said it experienced a stronger-than-anticipated finish to 2017 in a number of its businesses around the world. "Accordingly, the group now anticipates that underlying results for the year to 31 December 2017 will be ahead of our previous expectations," it said.
Helsby, meanwhile, would be succeeded by Mark Ridley, the current CEO of Savills UK and Europe operations, effective 1 January 2019.
Ridely would also join the board as deputy CEO on 1 May 2018.
Looking ahead to the current financial year, the company was a little more cautious with its guidance.
:In the current year, against the backdrop of heightened uncertainty over global economic prospects, geopolitical risks and rising interest rates, we expect some tempering of the strong transaction volumes of recent times in some markets," it said.
"Accordingly our expectations for 2018 remain unchanged."
