Norwood is responsible for the first Sussex commercial car wash to be staffed entirely by those with learning disabilities.
The Future Clean venture in Lewes, funded by East Sussex County Council, follows the success of the north London area outlet in Hatch End.
An eco-friendly hand valet and car wash, it is based on social enterprise principles with trainees being taught work skills which will help them in the job market.
Norwood business manager Nigel Bolton said the charity wanted “to give the people we support meaningful opportunities in every aspect of their life.
“I’d like to thank the trainees for showing commitment to learn new skills and demonstrating the high standards that they can achieve.”
