"Source London", which will deliver 1,300 public charging points across London by 2013, is part of the Mayor’s plans for London to become the electric vehicle capital of Europe. 

Members will pay a £100 annual fee to charge their vehicles at any of these public charging points, which will be denoted by a single logo.

Drivers will be able to sign up to the scheme using a new website, www.sourcelondon.net, which also provides a "one stop shop" of information on electric vehicles, including charge point locations across the city.

The development of Source London, has been led by Transport for London in close collaboration with the London boroughs and a wide range of private sector partners – who will play a key part in funding and providing locations for the network's charge points. 

The move follows the recent announcement of a 100% discount from the congestion charge for electric drivers in the capital, as well as other low-emission vehicles.

Mayor of London, Boris Johnson, said: ‘Through the development of Source London, we are seeking to create the fertile conditions for electric vehicles to flourish to make our city the electric driving capital of Europe.’

Transport Secretary, Philip Hammond, added: ‘We recognise that for many people the car is an essential, not a luxury, and that is why we are prioritising spending on making the UK a world leader in ultra low-emission cars. Following the first round of our Plugged-in-Places scheme, cities like London are laying the groundwork for a national charge point network.

‘And thanks to our spending review settlement which secured over £400m for measures to promote the uptake of electric and ultra-low emission vehicle technologies, more areas will soon be able to join them.’
