Private ADHD or Autism Assessment vs NHS: UK Guide

Direct answerPrivate and NHS assessment routes can both be appropriate. The main differences are usually access route, waiting time, cost, service scope and what happens after assessment. The right choice depends on your needs and the requirements of any service that will use the report.

NHS pathways vary by nation and locality

Referral routes are not identical across England, Scotland, Wales and Northern Ireland, and local services can have different criteria and waiting times. NHS information recommends speaking with a GP or relevant local professional about the route in your area.

Private assessment can offer direct access

Private providers can often be contacted without joining a local NHS assessment waiting list. The trade-off is that the person funds the assessment and must check whether the provider’s scope fits the purpose for which the report is needed.

A private report does not control another service

A private diagnosis cannot compel an NHS team or prescriber to provide a particular treatment. Receiving professionals remain responsible for their own clinical decisions and may request additional information or assessment.

England has additional patient-choice routes

NHS patient-choice rights and Right to Choose discussions relate specifically to NHS England arrangements. They should not be presented as a single UK-wide pathway. Availability and eligibility also depend on the service and referral circumstances.

Questions before choosing

Consider urgency, cost, complexity, prescribing needs, whether you need multidisciplinary input, report purpose and what support will be available after the assessment.

Common questions

Is a private diagnosis less valid than an NHS diagnosis?

Validity depends on the quality and appropriateness of the assessment, not simply who paid for it. However, receiving services can set their own requirements.

Can I stay on an NHS waiting list while considering private assessment?

Local rules and circumstances vary. Check directly with the relevant NHS service rather than assuming.

Is Right to Choose available across the UK?

No. NHS patient-choice arrangements referred to as Right to Choose are specific to England.
