The Cabinet Office acquired 26 Whitehall in December 1998. The cost of refurbishing 26 Whitehall from then until December 2002 cannot be separately identified as the refurbishment was undertaken as part of an integrated project which included the refurbishment of the inter-connected 22 Whitehall and Admiralty Arch.
Since the major refurbishment works were completed, there have been no refurbishments undertaken at 26 Whitehall.
