Autism Services for Adults

Autistic Spectrum Disorder (ASD) can affect everyone differently. For many people, getting a formal autism diagnosis as an adult means you can move forward with confidence, knowing you can access the expert support you need to thrive.

We’re with you every step of the way

How an autism assessment works

To be able to help you in the most positive way, we first need to fully understand your neurodevelopmental makeup and needs. Our specialist team will conduct a thorough, expert autism (ASD) assessment to ascertain if you are, or you are not autistic.

step 1


If you’re worried that you may be autistic, our free screening process will give clarity and insight. It will be carried out by our psychology team, led by a consultant clinical psychologist. If the results are indicative of autism, we’ll recommend a diagnostic assessment to give a definitive answer.

step 2

Information Gathering

Before we arrange your assessment, we ask someone who knows you well (ideally since you were young) to fill in a report form and an online screening questionnaire so we can understand more about you and how you were as a child. This is because neurodevelopmental conditions like autism are always with us, right from birth.  A better understanding of your strengths and needs helps our clinical team with their assessment.

step 3


The assessment is carried out by either a clinical psychologist or a psychiatrist, who are experts in diagnosing autism in adults. During the appointment, we'll carry out a thorough clinical interview, which will cover a range of issues relating to your experience, making sure you feel heard and understood. As autism can present in a similar way to other conditions, our job is to differentiate between those and autism itself, to give you an accurate opinion on your presentation. Once the assessment is complete, you’ll have time to ask questions about the outcome.

step 4

Diagnostic Report

Following the assessment, we'll provide you with a comprehensive report giving a full breakdown of the assessment and our findings. The outcome will be clear and easy to understand and will include our recommendations, plus helpful signposting for ongoing diagnostic support.

step 5

Ongoing Support

Following your autism assessment, whether an autism diagnosis is reached or not, our expert team will guide you on what support options are available to you at Psicon. These can include therapeutic support packages, provided by clinical and counselling psychologists within our wellbeing service.

Understanding Autism

Cherishing unique minds

Neurodiversity is part of being human; a fact of life for millions of children and adults alike. And having a neurodevelopmental (ND) condition doesn’t mean you have a disease that needs to be cured, but that your neurological functions are organised differently to people who are neurotypical. An autism assessment is the first step to understanding your unique mind.

However, neurodevelopmental differences can cause great distress when not recognised or understood. Once fully assessed and diagnosed, we can offer tools, support and therapies to help individuals move forward with positivity, peace and purpose.

Some words from our patients

To give you an idea of how we work and how we might help you.

I was made to feel at ease straight away

The doctor was very patient and understanding and I was treated with the utmost respect. I came away feeling well informed and I have a plan moving forward for my condition.

Fantastic clinic. I would highly recommend.

I chose to go here to get diagnosed with autism privately. Sadly I have been let down by the NHS since my childhood in the 1980’s and I decided I had to go private, but I would say it was worth every penny and the long drive from my home. Lovely professional staff. Thank you.

Thank you once again for all of your help Psicon!

An outstanding company. Are always willing to help on the phone with any questions, concerns or problems. I would recommend them to anyone.

Quick efficient service.

I could not have been happier with timescales, responses and communication.

The centre is a lovely welcoming place and the professionals put my highly anxious son at ease.

We went to the children's centre to get my son aged 17, a private Autism assessment. From the start the staff were informative and helpful. The centre is a lovely welcoming place and the professionals put my highly anxious son at ease. In fact he even asked when we were going back! After negative experiences with the NHS and school, my son felt that he could finally access support that was right for him. Thank you 😊

Would highly recommend Psicon for any assessments

Absolutely amazing with my son, very easy to talk to and my son loved interacting with the staff.

I would recommend this service to anyone that I know.

I attended the practice in June of 2022. The practice had such welcoming and kind staff members. This really eased any anxieties I had about going to the practice, and set a very calming atmosphere.

Excellent communication and explanation throughout the assessments.

All staff seemed very knowledge, were prompt and courteous and we were given a conclusion by the end of the assessment

From the minute we arrived staff were welcoming and professional.

From the minute we arrived staff were welcoming and professional. Thank you for listening and helping my son to be as comfortable as possible. You were so attentive to his ways and the consultant, speech and language therapist had extensive knowledge and were able to pick up on things I wasn’t even aware of. The support throughout was amazing, everything was explained in detail and I would definitely recommend Psicon to others. Thank you again.

All practitioners were friendly, understanding and really knowledgeable

All practitioners were friendly, understanding and really knowledgeable and informative about autism, but also girls and autism. They managed to put my anxious daughter at ease. They listened carefully, and were responsive to what we were saying. They also gave helpful suggestions to think about with the school and within the family.

They treated me like I was a person

They treated me like I was a person and demonstrated they treat each individual on a case to case base using treatments tailored to the individuals needs. They listened without judgement offering to treat individuals with complex needs.

Exceptional service.

The sessions were well organised. The psychologist was outstanding and it was like they knew me after just a couple of sessions. I would 100% recommend this service. I feel so much better and am going forward with several tools to keep me mentally healthy. I cannot recommend this service enough.

As a parent, it gave me the reassurance that my daughter will grow up knowing how her mind works

My daughter came out of her ADHD assessment feeling very positive about herself and empowered. As a parent, it gave me the reassurance that my daughter will grow up knowing how her mind works and what she needs to put in place to help herself along the way. We are very grateful to have been given such high quality care.

All staff are trained immaculately!

All staff are trained immaculately! Very kind, very helpful. Just wonderful. I could not have asked for a better service!

Frequently Asked Questions

Anything you’d like to ask us?

Taking the first steps to understanding why you feel different, unhappy, or struggling takes courage. We’re here to help you find the support that’s right for you.

See all our FAQs

How long is the waiting list?

This often depends upon how quickly we receive the pre-assessment information, but once we've received all questionnaires, we aim to provide an assessment appointment within four to six weeks.

If it's not autism, then why do I feel different? What do I do now?

We know that often clients attend their assessment with the feeling that the process will confirm something they already know. So, coming away from an assessment having been told that autism isn't diagnosed can be quite distressing and difficult to understand. Autism can be tricky to diagnose later in life, and often symptoms or traits of autism can overlap with other psychological or psychiatric conditions e. g. PTSD or Bipolar. Choosing an appropriately experienced and skilled clinician will mean that they can carefully unpick your symptoms and work with you to identify whether the way you feel is due to a neurodevelopmental condition like autism, or because of some other difficulties you may have faced in your life. If you do not receive a diagnosis, our clinical team will still be able to provide recommendations for further support and we may even be able to ask your GP to make an onward referral for another type of assessment should this be clinically appropriate.

I don’t have anyone to help with the pre-assessment questionnaires, will this affect my assessment?

We ask someone who knows you well to support the assessment process by giving extra information. This is because the Diagnostic Statistical Manual (DSM-5) states that to meet the threshold for a diagnosis of autism, symptoms/traits/behaviours must have been present from childhood. Put simply, autism is a neurodevelopmental condition caused by physiological differences in the brain, so will have been with you all your life. However, we understand that some people won't have anyone to support the process, and while this can make it trickier to conclude the assessment, it won't prevent the assessment from going ahead. If you aren't able to find someone to support you, we would advise you to bring as much information as you can that shows your strengths and needs as a child, for example old school reports.

Will a private diagnosis be accepted by the NHS?

Our assessments fully comply with NICE guidelines, and we use the highest quality and well-regarded clinical model within our service. We are also a trusted NHS provider and often support different NHS Trusts and ICBs with waiting lists. This means a diagnosis made by our service will be accepted by the NHS.

Is autism different in women?

While the assessment process and diagnostic criteria are the same across the gender spectrum , it is true that autistic women can present very differently. The criteria on which a diagnosis is made is largely known to be associated with symptoms in men and this can mean that women who are autistic may go undiagnosed. Men often present their symptoms in a more obvious or ‘stereotypical’ way, whereas women may have more subtle traits. This is because women often learn how to hide their symptoms (mask) in order to fit in with their peers. Having assessed thousands of people for autism, we are used to seeing it present in many different ways. Our assessments are designed to take masking and camouflaging into account – especially in women. Our team are very well trained in understanding the female presentation of autism and know that traits and symptoms can be trickier to see in women.
