Code Club is set to hit its target of signing up 25% of UK primary schools by the end of 2015, with London-based schools leading the way.
The free volunteer network runs after-school clubs for children aged between nine and 11.
September saw the introduction of the new computing curriculum in UK primary and secondary schools, meaning children from the age of five will now be taught to code.
According to Code Club, London’s primary schools are steaming ahead, with 20% of the city’s schools signed up.
Tower Hamlets has the most schools involved so far, with 46% of its primary schools signed up to the scheme. Through its partnership with the Canary Wharf Group, Code Club claims the number of clubs in the borough has increased by 163% in the past year.
Canary Wharf Group partnered with Code Club in December 2013, launching the initiative at technology accelerator Level39 in Canada Square. The partnership aims to deliver after-school coding classes to 75% of Tower Hamlets' 69 primary schools by the end of 2014.

So far, Level39 has hosted four Code Club sessions, where 57 volunteers were trained.
According to Code Club, for every training day an estimated 15 volunteers are trained, who then go on to train 900 teachers each year. This means an average of 13,500 children are reached by the scheme yearly.
Managing director, Code Club, Laura Kirsop said it is fantastic to see coding being given the attention it deserves.
"Children should not only use technology, but be able to understand it and develop it too," she said.
“The high level of take-up in Tower Hamlets has shown the importance of buy-in from the local community, business leaders such as Canary Wharf Group, technology professionals and schools."
Sir George Iacobescu, chairman and chief executive officer for Canary Wharf Group, said: "We are proud to be part of such a valued educational initiative that is making real strides in providing the children of Tower Hamlets with the skills they need to become the highly qualified workforce of tomorrow."
