One of Britain’s top accountancy firms is quitting London’s main financial district and moving its City staff to Canary Wharf.

It puts all KPMG’s London staff and partners in one location.

The firm has selected 30 North Colonnade to replace its Salisbury Square office which has a lease expiring in 2015, it has announced today.

It follows “an extensive search” in the Square Mile and east London property market.

The firm is taking up 200,000 sq ft across the top eight floors of the tower block, which was selected for its “collaboration advantages” of their adjoining 15 Canada Square HQ.

Some 1,100 staff are being relocated from Salisbury Square in 2015, to work alongside the 5,000 staff already in Canada Square.

KPMG chief Jim Marsh said: “The decision to relocate our City office to Canary Wharf offers an opportunity to accommodate all our London partners and staff in one central location, to enhance collaboration.”

The streamlining follows a previous relocation from various offices in the Square Mile in 2010.

But the firm continues its presence in the City when it takes a lease on a conference and meeting facility for clients, though plans for this are still under wraps.
