The voluntary and community sector umbrella group Community Action Southwark has changed its name to Community Southwark after going through a merger last summer.
Community Action Southwark announced a merger with Volunteer Centre Southwark in May.
The charity said its new name, which was adopted on Friday, was part of a change in strategy to focus on social action and work with volunteers as well as continue its role as a voice for voluntary and community groups in the London borough.
Community Southwark said it had agreed a three-year contract worth £1.2m with Southwark Council to deliver infrastructure services in the borough and support and advice for volunteers and individuals who want to be more engaged in their communities.
A spokesman for the charity said this contract was one of the reasons why Community Southwark reviewed its strategic priorities and increased its focus on communities and individuals.
The new charity is expected to have an income of approximately £1.3m in the 2016/17 financial year.
Four new members of staff have been hired since the merger was completed, taking the total number of employees to 24.
The spokesman said there had been no changes in the existing management structure, but a number of roles in the charity had changed to reflect the new broader remit.
Community Southwark is also establishing several community action networks to provide opportunities for individuals and groups to take action in their local areas.
Gordon McCullough, the chief executive of Community Southwark, said: "What is really exciting about Community Southwark’s new direction is that it means we are here to enable others to take steps to make positive things happen in communities across Southwark, while at the same time we will remain fully committed to supporting and being a voice for the borough’s thriving voluntary and community sector."
