Meet our founder
“I have ADHD and autism myself, so I know how much it matters to feel understood.”
Not judged, not rushed. I built AuDHD Psychiatry to be that kind of place, for adults and children alike. In this short video, I share what we stand for, and why.
Coaching and support after diagnosis
Autism isn’t something to treat with medication, so our support focuses on what helps day to day.
- Coaching built around your own goals
- Strategies for work, study and relationships
- Help putting your report into practice
- Support with sensory needs

Questions and answers
Adult Autism Assessment FAQs
Quick answers to the questions people ask us most before booking.
What if I think I might have ADHD too?
Many people recognise traits of both, and autism and ADHD often overlap. If that sounds like you, our combined AuDHD assessment looks at both in one coordinated pathway, so you don’t need to repeat your history twice. Mention it on your free consultation call and we’ll help you decide which assessment fits best.
Is there a single test for autism?
No single test can diagnose autism on its own. Instead, we use a structured combination of clinical interviews, validated questionnaires, and clinical observation, carried out by experienced psychologists. This helps us tell autism apart from conditions it’s often confused with, such as social anxiety or ADHD. Every assessment follows NICE guidance and is diagnosed against the DSM-5 criteria used across the UK and internationally.
Do I need a GP referral to book?
No, a GP referral isn’t required. You can book any of our assessments directly through our website, and we’ll confirm your appointment straight away, with no waiting for a referral or approval from anyone else.
How soon can I be seen?
Appointments are available within 7 days of booking, not the months-long waits that are common elsewhere. Once your appointment is confirmed, we’ll guide you through everything you need beforehand, including any forms or questionnaires, so you’re fully prepared when the day arrives.
Is an online autism assessment as reliable as in person?
Yes. Assessments are carried out over video call by the same clinicians and to the same clinical standard as an in-person appointment. Many people find being in their own space helps them feel more relaxed and able to be themselves, and it doesn’t matter where in the UK you’re based.
Do I need an informant?
No, it’s optional. We do recommend one if you can, as someone who knows you well, such as a partner, parent, sibling or close friend, can add helpful detail. They don’t need to have known you as a child. If there’s no one you’d like to involve, we can still carry out a thorough assessment using your own account, our clinical observations, and questionnaires.
What if I’ve learned to mask?
Masking – consciously or unconsciously hiding autistic traits to fit in – is very common, especially in women and in adults who’ve spent years compensating. Our clinicians know it well and are trained to look beyond it. We don’t rely only on how you present on the day; we also draw on your life history, questionnaires, and, where available, informant input. You won’t need to prove anything, and masking won’t stop us understanding you.
What happens if I don’t receive a diagnosis?
We’ll always talk you through the results in detail. If you don’t meet the criteria for autism, we’ll explain our reasoning and discuss other possible explanations for what you’ve been experiencing. Where it would help, we’ll point you toward other appropriate support, whether that’s back to your GP or another service that makes more sense for you.
Will my report be accepted by my GP, employer or university?
Our reports are accepted by most GPs, employers and universities, and can support requests for reasonable adjustments or Access to Work. That said, how an individual organisation chooses to act on a report is ultimately down to their own policy, so it’s worth checking directly with them if you have a specific requirement.
What support is available after an autism diagnosis?
Autism itself isn’t treated with medication, so your report includes practical recommendations to help day to day, at work, at home and in relationships. We also offer coaching from psychologists who specialise in autism, helping you put those recommendations into practice. If ADHD is also suspected, we can talk through assessment and treatment options for that too.
What if I’ve already been assessed elsewhere?
If you’ve already had an assessment elsewhere, we can review your existing report and talk through your options. That might mean a second opinion, ongoing support, or shared care going forward – whatever’s most useful for you.
Do you offer payment plans?
Yes. We offer payment plans through Klarna, letting you split the cost into 3 monthly payments, so cost doesn’t have to be a barrier to getting assessed.
