Whizz Kidz: The facts

Over 75,000 young people aren’t getting the wheelchair or support that fully meets their needs. Without the ability to be independent young wheelchair users are restricted in their ability to socialise and participate in society.

We’re here to change that. As the UK’s leading charity for young wheelchair users (9 months – 25 years old), we empower young people by providing the wheelchairs, equipment, support and confidence‑building experiences they need, and campaigning for a more inclusive society.

We won’t stop until they are mobile, enabled and included.

Our vision

A society in which every young wheelchair user is mobile, enabled and included.

Our values

We are young people focused, ambitious, collaborative and inclusive.
