Stage 1Getting started
The intake form and screening questionnaires are free.
Refer yourselfA few minutesOnline
You can refer yourself directly, no GP referral is needed. Start a short online form telling us a little about you and what you’re hoping to understand. We’ll review it and be in touch to arrange the next step.
The first question checks whether you need urgent help right now, so we can point you to it.
Not sure yet?
- Book a free call to find out whether it’s right for you.
Intake formFreeAbout 10–15 min
A secure online form about your history, development and what you’d like to understand. There’s no charge for this step.
It saves as you go. You can stop at any point and pick up where you left off.
Screening questionnairesFreeOnlineBy phone +£50
A few short questionnaires, also free. They look at both autism and ADHD, whichever you were referred for, because the two often occur together.
If you’d prefer, a clinician can go through them with you by phone for an additional £50.
Phone call reviewBy phoneWith your psychologist
Once the screening is back, your psychologist phones you to talk through the results and the options, including which assessment would help most.
-
Stage 2Full assessment
After the phone call review, you and your clinician decide together whether a full assessment is right for you. If it is, these steps open up.
Securing your assessment£300 deposit
If you decide to go ahead, we’ll ask for a £300 deposit, which unlocks the main questionnaires. It is taken off the total, and the balance is due before your assessment appointment.
Paying
- You can pay securely by card from the Payments section of your portal.
QuestionnairesOnlineAt your own pace
Recognised, validated questionnaires, completed online at your own pace.
What we’ll ask of you
- Complete the intake form and questionnaires when they appear in your portal. We’ll remind you if something is waiting.
Reports from othersSecure linkNo login for them
Someone who knows you well completes a short questionnaire through a secure link. It helps most if they knew you as a child, such as a parent or older relative, but a partner or close friend is also useful.
What we’ll ask of you
- The portal gives you a secure link to send them by email or text.
- If there’s nobody suitable, tell us and we’ll adapt.
Assessment appointmentUsually by videoFace to face +£100
An in-depth clinical interview. Autism assessments also include a structured observation, usually by video, with a face-to-face session where it’s needed.
You can add it to your calendar, join the video call from your portal, and cancel it yourself up to 24 hours before.
What to have ready
- A device with a camera and microphone, a steady internet connection, and a quiet, private room.
- Let us know about anything that would make the process easier, such as extra breaks or other adjustments.

FAQs
Questions people often ask
Do I need a GP referral?
No. You can refer yourself directly, there’s no need to see your GP first or to be on an NHS waiting list. If you’d like, we can share your outcome with your GP afterwards with your consent.
How soon can I be seen?
Usually within a month. Much of the time is spent waiting for questionnaires and reports from others, so returning these promptly keeps things moving. The portal shows where you are at every step.
Do you prescribe medication?
We don’t prescribe medication. If medication might help, we’ll explain the options and how to access a prescribing service.
Who else might you need to hear from?
With your consent, it can be helpful to gather information from someone who knows you well, such as a partner or parent. For children and young people, we ask for information from school as a standard part of the assessment. If that isn’t possible, we’ll agree another way to understand how things are at school.
What if I don’t meet the criteria?
Not everyone who is assessed meets the criteria for autism or ADHD, and that’s a valid and useful outcome. You’ll still receive a clear formulation that helps explain your experiences and points towards support that may help.
