The Two-Tier ADHD System in the UK: Private Clinics, Waiting Lists & What Can Change
Across the UK, adults seeking an ADHD diagnosis are facing an impossible choice: wait years for an NHS appointment or pay thousands for a private assessment. This two-tier system is leaving many people without timely support – and it’s a growing crisis.
The State of ADHD Services in 2025
NHS waiting lists for ADHD assessments often stretch 3–5 years in some regions. For many, this means struggling without answers, medication, or workplace accommodations. Meanwhile, private clinics have sprung up nationwide, offering quicker assessments – for those who can afford them.
As the ADHD Foundation highlights, “We are facing an unprecedented surge in demand, and the system is not yet equipped to meet it.”

Concerns Over Private Clinics
While private assessments can be life-changing, there are concerns:
- Cost: £800–£2,000 for assessments puts them out of reach for many.
- Quality: Some clinics are accused of “overdiagnosing” without rigorous standards.
- Equity: Access to support is becoming dependent on wealth, deepening inequality.
The Human Cost of Delays
Undiagnosed ADHD can lead to:
- Job instability
- Relationship breakdowns
- Higher risk of depression, anxiety, or substance use
- Financial stress from underemployment or impulsive spending
What Needs to Change
- Increased NHS funding for neurodevelopmental services.
- Clear, standardised diagnostic guidelines across sectors.
- Public education campaigns to reduce stigma and raise awareness.
- Hybrid models blending NHS oversight with private-sector speed.
