Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what steps his Department is taking to help ensure that local health authorities provide parents with clear information regarding expected waiting times for autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) assessments for children; and whether he plans to implement a standardised minimum waiting time announcement for such appointments.

There are currently no plans to implement a standardised minimum waiting time for autism and attention deficit hyperactivity disorder (ADHD) assessments for children.

The National Institute for Health and Care Excellence (NICE) guideline for the diagnosis of autism recommends the length of time between referral and first appointment should be no more than 13 weeks. We know that this is not happening routinely across the country. In respect of ADHD, the NICE guideline does not recommend a maximum waiting time for people to receive an assessment for ADHD or a diagnosis, however it sets out best practice on providing a diagnosis.

The Government has recognised that, nationally, demand for assessments for autism and ADHD has grown significantly in recent years and that people are experiencing severe delays for accessing such assessments. The Government’s 10 Year Health Plan will make the National Health Service fit for the future and recognises the need for early intervention and support.

It is the responsibility of integrated care boards (ICBs) to make available appropriate provision to meet the health and care needs of their local population, including provision of autism and ADHD services, in line with relevant NICE guidelines.

Through the NHS Medium-term planning framework, published 24 October 2025, NHS England has set clear expectations for local ICBs and trusts to improve access, experience, and outcomes for autism and ADHD services over the next three years, focusing on improving quality and productivity.

The Secretary of State announced on 4 December 2025 the launch of an Independent Review into Prevalence and Support for Mental Health Conditions, ADHD and Autism. This independent review will inform our approach to enabling people with ADHD and autistic people to have the right support in place to enable them to live well in their communities.
