Complaints about autism and ADHD services in England have more than tripled in five years, with the NHS ombudsman warning that long waits and inconsistent care are creating serious problems for patients and families.

New figures show complaints rose from 410 in 2021–22 to 1,257 in 2025–26, while around 562,000 referrals are currently open for autism and ADHD assessment and support. More than 60% of patients are reportedly waiting longer than a year.

The ombudsman has highlighted cases involving patients being removed from waiting lists without adequate explanation, difficulties accessing medication and confusion over patients' rights to choose alternative providers. Some families have turned to private healthcare after prolonged NHS delays.

The government has appointed Professor Peter Fonagy to lead an independent review examining autism, ADHD and related mental-health services, with recommendations expected later this year.

The sharp rise in complaints is putting renewed pressure on the NHS to address capacity, waiting times and consistency of neurodevelopmental care.
