Savills has leapfrogged to the top of the central London agent's league table in quarter one. Boosted by the Google mega deal, the agency has shot up from 5th place at the end of last year notching up an impressive 1.1m sq ft of disposals in Q1, and bagging nearly a third of the London market. DTZ is in second place having acted as joint agents with Savills on the 860,000 sq ft prelet to internet giant Google at King's Cross Central in January, according to EGi's London Office Market Analysis released today.
