The charity will focus on the needs of people with mild and moderate learning difficulties. Chief executive Sally Warren said: "We will concentrate on those who may not outwardly appear to need help but in order to live independent lives need some support."
The charity has dropped Wandsworth from its name as it will also expand its focus to neighbouring London boroughs. Warren said: "We don't want to duplicate but we do provide some services that are not catered for in surrounding boroughs. We also want to become a national voice promoting the needs of our clients."
The charity, which was founded 30 years ago was named after Elfrida Rathbone, a pioneer for the education of disadvantaged children.There are many independent charities around the country named after her.
