TELCO is the founding network of London Citizens, the capital's largest and most diverse alliance of active citizens and community leaders. London Citizens has over 83 member organisations, including faith congregations, schools, student organisations, community associations, trade union branches and resident groups. Members share a commitment to taking action for the common good, and helping people of all backgrounds and ages to become active leaders who can help shape the public life of the city.

Originally formed as the East London Community Organisation (TELCO), London Citizens has since expanded with the new South London Citizens and West London Citizens networks. By joining together through London Citizens, local organisations across the city have created an influential people's organisation with the power to create positive change in their communities.
