A group of 45 staff, suppliers, customers and family and friends from Howarth were sponsored to climb the 978m Scafell Pike in the Lake District.
Caudwell Children provides equipment, treatment, therapies and support for disabled children and their families in the UK.
Howarth and the charity are in the second year of a three-year partnership, and Howarth holds regular fundraising events. Last year a team from the company completed the Yorkshire Three Peaks challenge in aid of the charity, while golf and cricket events have been held this year.
