The donation was raised through a national verified scheme that recycles metals which remain after cremation with the express consent of bereaved families, such as items used in the construction of the coffin or orthopaedic implants.
The Swan Song Project, was chosen by colleagues at The Oaks to receive £15,000 due to the positivity it created around a subject that is often treated as taboo.
It gives people facing end of life and those surrounding them the opportunity to write and record their own original song.
Swan Song founder, Ben Buddy Slack pictured, said: "For a charity our size, this donation really does make such a huge difference and we really appreciate the support.
"It is a very exciting time at Swan Song as we aim to make our unique service available across the country.”
