Diageo plans to close its headquarters in central London by the end of the year, in a bid to save £100 million.
The global drinks giant plans to close Henrietta place in central London and move its operation to a single site in Park Royal, north west London.
A spokesperson said: "At Diageo’s half year results on 12 February 2009 we announced our intention to implement a restructuring plan in the second half of our financial year.
“This restructuring plan will create anticipated full year savings of £100 million that will largely accrue in F10, which begins on the 1st of July 2009.
“The savings will come from costs of goods sold and overheads - which include running costs, facilities and employees – and contributions to these savings will come from most parts of the business around the world.
“As part of this plan, Diageo is currently consulting with its London based staff on a proposal to move to a single London operation, based in our existing purpose built office in Park Royal.
“This would result in the closure of the Henrietta Place office by the end of 2009."
