Private autism assessment in Scotland and the wider UK

Caledonian Psychiatry provides private adult autism (ASD) assessment to adults across Scotland by secure video. Assessments are carried out by Dr David Crocker, a GMC-registered psychiatrist (MRCPsych), and the practice is regulated by Healthcare Improvement Scotland (reg. 03427). If you want to know what the autism assessment involves clinically, that page sets it out in full. This guide answers the practical questions: whether to go private, what it costs, how long it takes, and what a diagnosis changes.

NHS or private? The reality in Scotland

Adult autism assessment services across NHS Scotland are under considerable strain, and the data from individual health boards illustrates just how severe the situation has become. In NHS Grampian, fewer than 6% of adult autism referrals were assessed over a two-year period, with waits exceeding two years (freedom-of-information data, 2023). NHS Tayside reported 843 adults waiting for an autism assessment, with the longest wait reaching five years (FOI, August 2024). As of March 2025, around 23,300 adults were waiting for a neurodevelopmental (autism or ADHD) assessment in Scotland, with a median adult wait of about 76 weeks; most health boards see fewer than half of patients within the recommended 36-week standard (Scottish Parliament, 2025).

These are not outliers — they reflect the structural position across Scotland. For many adults, that wait is not realistic alongside the demands of work, study, relationships, or mental health.

It is also worth noting that the ‘Right to Choose’ pathway that operates in England, which allows patients to be assessed at an approved independent provider at NHS cost, does not apply in Scotland. Scotland has its own NHS commissioning arrangements, and there is no equivalent opt-out route available here. For more background, see our articles on Right to Choose in Scotland and NHS waiting times in Scotland. A private assessment is self-funded, but it can be arranged within weeks rather than years.

What a thorough adult autism assessment involves

A credible autism assessment is considerably more involved than a questionnaire. At Caledonian Psychiatry, the assessment takes place over two 60-minute video appointments and draws on a full suite of validated diagnostic tools (the AQ-50, EQ-40, RAADS-R, Reading the Mind in the Eyes Test, and the CAT-Q — the Camouflaging Autistic Traits Questionnaire, which measures masking directly and is particularly informative for women), a detailed developmental and social history, behavioural observation during the consultations themselves, and a collateral history from a family member or someone who knew you as a child — obtained with your consent, as ICD-11 requires evidence that features were present during the developmental period.

For a full account of the diagnostic framework, the tools used, and the standards the assessment follows, see the autism assessment page and our approach.

How much does a private autism assessment cost in Scotland?

The autism assessment at Caledonian Psychiatry costs £800, covering two 60-minute consultations and a detailed written diagnostic report. There are no hidden charges for the assessment itself. See the fees page for a full schedule of charges.

If there is any possibility that ADHD may also be present — the two conditions frequently co-occur and can be difficult to distinguish without assessing both — a combined ADHD and autism assessment covers both in three 60-minute sessions at £1,300. This is often the more efficient and clinically thorough approach when both are suspected.

How long does it take?

At Caledonian Psychiatry, most adults are seen within weeks of getting in touch. The assessment itself takes place across two appointments, with the written report following shortly after the second session. Compared to the median wait of 76 weeks across NHS Scotland’s adult neurodevelopmental services, the difference is substantial for people whose daily lives are affected now.

After a diagnosis — what changes

For many adults, a formal autism diagnosis brings clarity to experiences that may never previously have been understood — a framework for a lifetime of feeling different, exhausted in ways that are hard to explain, or out of step with peers. That self-understanding is itself valuable, often enabling greater self-compassion and more deliberate choices about work, relationships, and how energy is managed.

Practically, a diagnosis from a GMC-registered psychiatrist is a formal clinical diagnosis. It carries the same standing as an NHS diagnosis and can support a range of practical outcomes: reasonable adjustments at work or university under the Equality Act 2010, applications for benefits such as PIP, access to support services, or onward NHS referrals. Employers and educational institutions are familiar with private autism diagnoses from registered specialists; the key is that the assessment is carried out by a qualified clinician following recognised diagnostic criteria.

Autism itself is generally not treated with medication, so shared care with a GP is not typically part of the picture after an autism assessment alone. If ADHD is identified alongside autism, that is a different matter — see the autism assessment FAQ for more on what happens when both conditions are present.

Getting assessed from anywhere in Scotland

Because every appointment is delivered by secure video, there is no need to travel. Caledonian Psychiatry sees adults from Edinburgh, Glasgow, Aberdeen, Dundee, Inverness, and across the Highlands, Islands, and the rest of Scotland. The assessment works exactly the same way regardless of where in Scotland you are based.
