Why Families Consider Private Assessment

Frequently Asked Questions
Is a private ADHD diagnosis recognised by schools?
In many cases, yes—where the assessment is completed by a suitably qualified clinician using recognised diagnostic criteria and a written report is provided. Schools may still request additional evidence to plan appropriate support.
Can a private autism diagnosis support an EHCP application?
A formal diagnostic report can contribute evidence for an EHCP request or assessment. EHCP decisions are made by the local authority based on the child’s needs and the evidence available, so diagnosis is one part of the overall picture.
Will my GP accept a private ADHD diagnosis?
This varies by GP practice and local NHS arrangements. Some GPs may enter shared care for ADHD medication where appropriate, while others may not. It’s sensible to check local prescribing arrangements before booking a private assessment.
How long does a private ADHD assessment take?
This varies by provider, but many assessments include an initial clinical appointment plus time for questionnaires, history-taking, and a written report. Some providers complete the process across multiple appointments.
How long does a private autism assessment take?
Autism assessments often involve more than one appointment and may include multidisciplinary input. Timeframes vary depending on the provider’s model, the information needed, and report turnaround times.
What should I check before booking a private assessment?
You may wish to confirm the clinician’s professional registration, the diagnostic framework used, what is included in the fee, whether follow-up support is available, and whether any prescribing or shared-care arrangements are realistic in your area.
Can private assessments be done remotely?
Some providers offer remote assessments by video. Whether this is suitable depends on the individual, the provider’s model, and the information required. Families can ask how observations and collateral information are gathered remotely.
Does a private diagnosis guarantee medication or an NHS prescription?
No. Medication decisions depend on clinical assessment and prescribing arrangements. NHS prescriptions and shared care are handled locally and may vary between GP practices and NHS services.
How does Find Support UK review private assessment providers?
Providers may apply for verification, which includes confirmation of organisational identity, transparency of service scope, and alignment with recognised diagnostic frameworks where applicable.
Verification does not constitute clinical endorsement or regulatory approval. Families should always review a provider’s qualifications, registration status, and published assessment process before booking.
Listings are clearly labelled to indicate whether a provider is Listed, Verified, or Featured.
