The purpose of this guidance is to secure the implementation of the Adult Autism Strategy “Fulfilling and Rewarding Lives: The Strategy for Adults with Autism in England” 2010 as updated by Think Autism (2014) by giving guidance to Local Authorities, NHS Foundation Trusts and NHS bodies. The guidance focuses on the areas which section 2 of the Autism Act 20097 requires to be addressed, in each case identifying what Local Authorities, Foundation Trusts and NHS bodies are already under a duty to do under legislation, what they are expected to do under other existing guidance, and what they should do under this guidance. Local Authorities, NHS bodies and Foundation Trusts should already be doing much of what is expected of them in complying with this guidance as they should have followed the 2010 statutory guidance (which this guidance builds on and replaces).
