Leonard Cheshire is the largest voluntary sector provider of support services for disabled people in the UK.
However, recent research carried out by the charity revealed that only one in five people under the age of 35 had heard of Leonard Cheshire; and an even smaller number knew what the charity does.
Judith Barnard, the Leonard Cheshire director of communications, said: "We are proposing to relaunch Leonard Cheshire towards the end of the year.
"Leonard Cheshire is considering ways in which we can better promote disability issues, and get wider public support. We exist to serve disabled people and we wish to be in the best possible position to do this."
