Jason Durr, best known for playing David Hide in the BBC drama Casualty, is taking on a 90ft abseil down Great Western Hospital.
The actor, who lives in Wiltshire, is facing the challenging descent to raise funds for Brighter Futures, Great Western Hospitals NHS Foundation Trust’s charity.
On Saturday 18 January, Jason will scale the side of the hospital along with around 50 others.
All funds raised will go towards improving services on the Children’s Ward, including the continued funding of a music therapist provided by charity CALM.
Jason said: “The Great Western Hospital is my local hospital and has cared for many of my family members over the years.
“We have always received such good care and I just wanted to give something back and raise some money. This really is about the kids, and it is so important that I help in any way I can.
“If we can make the children’s experiences in hospital that little bit better, then I want to do my bit – even if that means dangling off the side of the hospital.
“I’m feeling a little bit nervous for the abseil but I know that I will be in safe hands. I’m also feeling excited, as I know that tacking on this challenge is raising money for really important things.”
Michelle Leighton, Community and Events Fundraising Manager, said: “We are so thrilled that Jason Durr has signed up to take on our abseil, along with the number of other generous people who are also taking part on Saturday.
“We still have a few places available, and ask that anybody who wants to participate should raise a minimum of £80, with a £20 sign-up fee.
“Thanks to your support, we can improve the experience for some of our youngest patients, making their stay in hospital that bit better with the support of a music therapist.”
