The Duchess of Cornwall will visit the Trinity Hospice in Clapham later.
Trinity Hospice is the oldest hospice in Britain, and provided care to more than 2,500 people with a range of terminal illnesses last year.
Over 450 of those patients were treated at the charity's inpatient center in Clapham.
The Hospice receives just a third of its income from the NHS, and needs to raise more than £7 million every year.
