Two new Northern Line stations could see Wandsworth commuters gain their first zone one train station.
Underground stations are set to be built in Nine Elms and Battersea Power Station as part of the multi-billion pound development of the region.
As part of this process Transport for London (TfL) will have to decide if the stations are to be part of zone one or two.
They were initially allocated to zone two but TfL is now proposing to put them in zone one
A final decision on the re-zoning will be made by the secretary of state for transport in the autumn.
Councillor Ravi Govindia leader of Wandsworth Council said: "Zone one status will draw more commercial occupiers to Battersea and help us create 25,000 new jobs in this underused part of the riverside.
"This tube extension has the potential to expand the central London economy into Wandsworth and deliver the growth, opportunities and new homes our city needs."
