ADHD & Autism Assessment Loans

The biggest difference is how you access the assessment. An NHS assessment is free, but you will usually need a referral from your GP. With a private assessment, you can often book directly with a clinic and choose an appointment that suits you. Private assessments also tend to offer more flexibility with appointment times. Both should be carried out by qualified clinicians and provide a detailed report to explain the assessment and any diagnosis.

In many cases, you do not need a GP referral for a private ADHD or autism assessment. You can often contact the clinic yourself and book an appointment directly. Some providers may ask for a few medical details before your assessment, but this varies. If you are going through the NHS, you will usually need a referral from your GP or another healthcare professional. It is always best to check with your chosen clinic first.

A private diagnosis from a qualified clinician is widely accepted, but every organisation has its own policies. Your GP, employer or school will usually accept the assessment report, especially when it clearly explains the diagnosis and any support that may be needed. In some cases, NHS services may carry out their own assessment before providing treatment. If you are unsure, it is always a good idea to check with the organisation beforehand.

Many people are diagnosed with ADHD or autism as adults. Some have always felt different but never knew why, while others only start looking for answers after their child is assessed or they learn more about the signs. A diagnosis can help make sense of experiences that may have been confusing for years. It can also help you access the right support and better understand how your brain works and what you need to thrive.

You do not need to worry about bringing lots of paperwork. Most clinics will ask you to complete a few questionnaires before your appointment and talk about your experiences growing up, your daily life and any challenges you face. If you have school reports or someone close to you can share their observations, these can be helpful, but they are not always essential. Your clinician will let you know exactly what is needed beforehand.

Private assessment costs can vary because every clinic offers something slightly different. Some clinics also offer assessments online, while others only see patients in person. Some include follow-up appointments, a detailed assessment report and support after your diagnosis, while others charge extra for these. Prices can also reflect the clinician’s experience and the time needed for the assessment. Before you book, it is worth checking exactly what is included so there are no unexpected costs later.

You will usually be able to stay with your child throughout their ADHD or autism assessment, especially if they are younger. Having a parent or carer there can help a child feel more relaxed and supported. You may also be asked questions about their development, behaviour and everyday life. Sometimes, the clinician may want to spend a little time speaking with your child on their own, but they will explain why and talk you through the process first.

A formal ADHD or autism diagnosis as an adult can help you make sense of things you may have found difficult for a long time. It can explain why you think, communicate or respond in certain ways and help you understand yourself better. It may also make it easier to access support, workplace adjustments or strategies that suit you. A diagnosis does not change who you are, but it can give you answers, confidence and a clearer way forward.

Some people have both ADHD and autism, a combination often referred to as AuDHD. This means they experience traits from both conditions, which can create a unique mix of strengths and challenges. For example, someone may be highly creative and energetic but also find planning, focus, routines or sensory experiences difficult. A combined assessment looks at how ADHD and autism traits appear together, helping to provide a more complete understanding of how someone thinks, works and experiences the world.

More adults are being diagnosed with ADHD and autism because people are becoming more aware of the signs and are feeling more confident about seeking answers. Many people reached adulthood without a diagnosis because their traits were overlooked, misunderstood or hidden by coping strategies they developed over time. With more information available and easier access to assessments, more people are exploring whether ADHD or autism could explain their experiences and help them better understand themselves.
