The Disabilities Trust is spearheading a "manifesto for change" to tackle autism.
The manifesto, which was unveiled at the Autism Awareness Year conference last week, calls for a range of measures to benefit children and adults with autistic spectrum disorders, their families and carers.
Among the improvements campaigners are asking for is an end to the postcode lottery of services, more money to educate the public about autism, and further research into the condition.
The campaign is at an early stage but will concentrate on an information push to social services professionals through representative bodies and parents backed by a government lobbying campaign.
Stephen Ladyman MP, who spoke at the conference, is to promote the manifesto to MPs through his position as chair of the all-party parliamentary group on autism.
