Swimming in the hydrotherapy pool at Chestnut Tree House

Your sponsorship helps make magical moments:

We all love splashing about in the pool together. It’s one of the very few times when all four of us can be together as a family, all enjoying the same thing.

Liz, Luke’s mum

How does your fundraising help?


could pay for three families to use our hydrotherapy pool with a specialist nurse


could provide a day of fun, laughter, care and support for a child with a life-limiting or life-threatening condition


could give two families of four an overnight stay, allowing a rare chance to watch a film together, or catch up on sleep knowing their child is being cared for

Let's get social
