Naomi House

Naomi House & Jacksplace hospices provide expert hospice care to more than 280 life-limited and life-threatened children, young people and their extended families from Hampshire, Wiltshire, Dorset, Berkshire, West Sussex, Surrey and the Isle of Wight.

The teams take time to really get to know the families and fully understand their wishes. Naomi House & Jacksplace offer them vital respite support, giving them the chance to recharge their batteries and regroup in a calm, fun and welcoming environment. In times of emergency Naomi House & Jacksplace is there, giving families the help they need through difficult times. And at the end of a child or young person's life, the charity pulls out all the stops to give them a peaceful and dignified end, surrounded by family members.

This standard of care costs money; £7 million per year to be precise. With only 10% of income coming from Government and statutory sources, Naomi House & Jacksplace are reliant on the support of people like you.

That's where Naomi House & Jacksplace needs you! Why not join the team for the May Day Triathlon? Your effort in the race, and build up of donations, will allow the charity to continue their long-standing care for these children & young people, as well as their extended families.

These help to make a real difference and give every child the optimum chance of getting better, the parents to be comfortable and able to focus on being with their child, and their extended families and friends to know that they are receiving the very best of care.

Every penny we spend is received as a result of the generosity, ingenuity and huge efforts of our many amazing supporters. Our heartfelt gratitude goes out to all the participants whose efforts and results at events such as the May Day Triathlon give us the opportunity to help the babies and children and are inspiring to others who would like to help raise funds and awareness for the charity. Thank you from our Trustees, Patrons, the staff on PICU and all who support FoPICU for taking on the challenge!
