Platinum Facilities has retained its hard services contract at 10 Queen Street Place, in the City of London, for another five years.
The contract was awarded by real estate consultancy Knight Frank.
Platinum Facilities has supplied services at the building for 14 years.
The contract was first won in 2006, when the occupant was law firm SJ Berwin, and retained in 2013, when the business merged with another legal firm, King & Wood Mallesons.
Platinum's services were again retained in 2017, when Knight Frank moved in and the FM team supported the property consultant through a complete building fit-out.
