Twelve-year-old Dani Jacobson was runner-up in the Channel Five search for "Britain's Kindest Kids", presented by Natasha Kaplinsky.
The North London Collegiate pupil received 35 per cent of the vote for a 22-mile swim with her learning disabled sister Talya which raised over £23,000, mostly for Norwood.
And as the contest winner, Liam Fairhurst, offered to share his £1,000 prize with the four other finalists, Dani will be handing over a further £200 to the charity.
