Work is planned to accelerate transport improvements ahead of the opening of the Westfield development at Shepherd's Bush, which opens in late 2008.
The station's ticket hall will be demolished and rebuilt, and new escalators installed, as part of the station modernisation.
Westfield and London Underground have agreed the station closure so that escalator works can be accelerated and completed before the retail development opens.
The escalators at Shepherd's Bush Central line station are nearing the end of their working life, and were scheduled for replacement in the next few years, but the new development will see significantly increased traffic, accelerating the need for replacement.
Richard Parry, London Underground’s Director of Strategy and Service Development said: "We always try wherever possible to avoid closing Tube stations because of the inconvenience to passengers. But we have reluctantly agreed to close this station for eight months because it means the works can be accelerated and the escalator works undertaken at the same time, which in turn will result in benefits to passengers being delivered faster with less overall disruption.
"Major transport benefits will be delivered as part of the Westfield development and will enable the majority of visitors to the new centre to travel by public transport. This will see the construction of world-class Tube stations at Wood Lane on the Hammersmith & City line and a vastly improved Shepherd’s Bush station on the Central line."
Westfield is funding £170M for transport improvements, including the rebuilding of Shepherd's Bush Central line station, and the new Wood Lane station on the Hammersmith & City line, which will open when the Westfield development opens in late 2008.
The Hammersmith & City station at Shepherd's Bush will be renamed Shepherd's Bush Market to eliminate confusion with the Central line station.
