Colliers CRE, which has an office in Manchester, has changed its company name to Colliers International UK.
The Colliers CRE Group, including Colliers Robert Barry, Colliers Godfrey Vaughan and Colliers Jackson-Stops, will now all trade under the new brand.
The firm said the rebranding is part of a "transformation from a traditional network to a consolidated organisation".
The rebranding has coincided with the announcement of eight new directors at Colliers International, including four at the Manchester office, two in development consulting and one each in corporate restructuring and hotels. The names of those based in Manchester are not being disclosed until a later date.
David Izett, chief executive of Colliers International UK, said: "In the UK we are the same team, with the same enterprising personality, committed to delivering client solutions of the highest calibre. We are, however, recruiting some impressive new talent and have recently appointed six new directors in key positions throughout the UK business.
"Being an integral part of the newly aligned Colliers International gives our clients access to a team of 15,000 professionals and through them, a myriad of important, often longstanding relationships as well as comprehensive knowledge and intelligent insight across international markets."
Colliers International has revenues of £1.2bn.
