The Family Holiday Association has become one of the first UK charities to be supported by the Tui Care Foundation.
The five-year agreement is designed to provide days out or short breaks for more than 7,000 struggling families.
It is estimated the partnership will benefit more than 16,000 children and 12,000 adults over the five-year period.
Helen Caron, member of the trustees board at Tui Care Foundation, said: “At Tui, we have supported the Family Holiday Association for many years and we are delighted that the partnership will now continue through the Tui Care Foundation.
“We know the positive impact breaks have on people’s wellbeing, and to be able to help those in desperate need who might otherwise miss out is as rewarding as it is worthwhile.”
The long-standing relationship between the FHA and Tui has raised more than £3.75 million over the last 28 years, funding 25,000 day trips and short breaks for about 60,000 children and their families.
The five-year agreement with the Tui Care Foundation aims to build on this legacy under the banner of the Tui Care Foundation Junior Academy.
John Kinnear, FHA head of programmes, said: “Millions of children and their families in the UK struggle daily with issues such as severe and long term-illness, bereavement, mental health issues, disability and domestic violence.
“Often these families don’t have the confidence or resources to arrange a break away from home and yet evidence consistently demonstrates that by taking some time away from the daily routine, adults and children are happier, healthier and often able to engage more with society, returning to employment or further education in some cases.
“We are absolutely delighted that the Tui Care Foundation has made this long-term commitment.
“The support will allow us to reach even more people, helping them to experience a break from the stresses at home, nurturing their wellbeing and creating cherished memories.”
Founded by Tui Group, Tui Care Foundation aims to build on the potential of tourism “as a force for good” by supporting partnerships and projects around the world.
