Autism services in London

Autism assessment in London is commissioned separately by each of the five London ICBs, which means the specific diagnostic service you are referred to and your waiting time depend on your borough. NHS trusts providing autism diagnostic services include South London and Maudsley, Central and North West London, and East London NHS Foundation Trust. Right to Choose availability for autism assessments varies across London's ICBs. Private autism assessment clinics are widely available in London.

Autism assessment in the UK requires a referral to a specialist diagnostic service. On the NHS, your GP refers you to a local autism assessment team. Waiting times for NHS autism assessments are among the longest in mental healthcare, with many areas reporting waits of several years for both adults and children. NICE guidance states that no one should wait longer than 13 weeks for an autism assessment, but the reality in most areas falls far short of this standard.

The NHS Right to Choose may allow you to request assessment from an independent provider funded by the NHS, though this pathway is less established for autism than for ADHD and availability varies by Integrated Care Board. Some ICBs do not currently commission Right to Choose autism assessments.

Private autism assessments are available without a GP referral from most providers. These typically offer much shorter waits. A private autism diagnosis is clinically valid, but it is worth checking in advance whether specific organisations (employers, universities, local authorities) will accept a private diagnosis for the purpose of accessing support or adjustments.

Unlike most other conditions on this page, autism is not something that is "treated" in the traditional sense. Post-diagnostic support focuses on understanding yourself, developing strategies for daily life, and accessing adjustments at work or in education. Some autistic people also seek support for related difficulties such as anxiety, sensory processing, or social communication challenges.
