The Metropolitan, Circle, District, and Hammersmith and City lines are to run 24 hours at weekends from 2017.
The lines will boost capacity on the ‘night Tube’ which will start later this year on the Piccadilly, Victoria, Central, Jubilee and Northern lines.
City Hall and Transport for London have previously said making it easier and cheaper for Londoners to get home later the evening and in the early morning will boost the city’s night-time economy.
Today Mayor of London Boris Johnson and Chancellor George Osborne announced that, in addition to the extra Tube lines, all-night services would run on the London Overground from 2017 and DLR by 2021.
The night services form part of a six-point economic plan the pair claim will add £6.4bn to the London economy by 2030 and create half a million new jobs.
A number of measures included in the Treasury’s plan, including extending the Northern Line to Battersea, plans to buy 200 additional New Routemaster buses and devolution of rail services from Liverpool Street to Chingford have been previously announced.
Two other schemes highlighted by the Chancellor – Crossrail 2 and extending the Bakerloo Line – are already been worked on by Transport for London.
Mr Osborne said: “I want these plans and others worked up, properly costed and prioritised so we can make a decision to go ahead in the government’s Spending Round this summer.”
Mayor Johnson said: Today we have committed to additional night Tube services, the first 24 hour London Overground and the purchase of hundreds of brand new buses.
“This, combined with the promise of future investment in projects such as Crossrail 2 and the Bakerloo Line extension, will ensure we keep the capital’s economy moving well into the 21st century.”
In addition to the re-announcements, the plan includes a number of new ideas, including establishing a London Land Commission which would identify and support the development of brownfield and public sector land to boost home building.
And a “feasibility study” will be set up to investigate the potential for a “world class concert hall” led by the City of London corporation’s Barbican Centre.
The plan also includes a commitment to “beginning discussions” on extra devolution to London, including additional planning powers and more responsibility for apprenticeship funding.
