You no longer have to sit in a clinic to be assessed for ADHD. Remote assessment has opened the process up to people who could never have managed an in-person appointment easily, whether because of distance, work, caring responsibilities or the sheer wait. That is a genuine improvement. It has also created a crowded market where the quality of what is offered varies enormously, and where a fast, cheap diagnosis is not always a diagnosis that will stand up later. Knowing what to check before you book is what separates a useful assessment from a wasted one.
Is the provider properly regulated?
Start here, because it underpins everything else. In England, healthcare providers carrying out clinical assessments should be registered with the Care Quality Commission, the independent regulator. CQC registration means the service has been inspected against standards for safety and quality, and you can look a provider up on the CQC website before you commit. If a provider is carrying out diagnostic assessments and you cannot find any evidence of regulation, that is a reason to pause. A diagnosis from an unregulated service may carry little weight with your GP or anyone else later on.
Who is actually doing the assessment?
ADHD is a clinical diagnosis, and it should be made by an appropriately qualified professional: a psychiatrist, or another suitably trained and supervised clinician working within a recognised framework. Before you book, it is reasonable to ask exactly who will assess you, what their qualifications are, and whether they are registered with the relevant professional body. A reputable provider will answer this clearly. Vagueness about who is responsible for your diagnosis is a warning sign, and so is a process that seems designed to keep the clinician at arm's length from you entirely.
Does the assessment follow the recognised process?
A proper ADHD assessment is not a quick questionnaire. Under NICE NG87, diagnosis rests on a full clinical interview covering symptoms across settings, their impact on daily life, and developmental history reaching back into childhood, since ADHD is lifelong rather than something that begins in adulthood. Screening questionnaires have their place as a starting point, but a diagnosis based on a tick-box form alone is not following the recognised standard. When you are choosing a provider, ask what the assessment actually involves and how long it takes. The answer tells you a great deal.
A fast diagnosis is not the same as a good one. The question is not how quickly you can be assessed, but whether the assessment will hold up.
What happens after diagnosis?
A diagnosis is the beginning of the work, not the end of it, so what a provider offers afterwards matters. If ADHD is confirmed and medication is appropriate, who initiates and monitors it? Under NICE guidance, ADHD medication is started by a clinician with specific expertise, with titration and follow-up over the following months. Some providers offer this; others diagnose and then leave you to arrange the rest yourself. Neither is wrong in principle, but you want to know which one you are buying before you pay, not discover it afterwards. Our piece on what happens at an ADHD assessment sets out the full process so you know what to expect at each stage.
Will my GP accept it?
This is one of the most common and most reasonable worries. A diagnosis from a properly regulated provider, made by a qualified clinician following the recognised process, is a legitimate clinical diagnosis. Whether your GP will enter into a shared care arrangement for ongoing medication is a separate question, and it depends on local NHS policy, which varies between areas. A good provider will be transparent about this rather than promising something they cannot guarantee. If a service implies your GP will automatically take over prescribing everywhere, treat that claim with caution.
Is it priced honestly?
Cost varies, and cheaper is not automatically worse, but the structure of the pricing tells you something. Be clear on what the headline price includes: the assessment itself, the written report, any follow-up, and the cost of medication titration if relevant. Hidden add-ons that only appear later are a poor sign. So is pressure to book quickly or pay upfront for a package before you have had any proper contact with the service. A trustworthy provider gives you the full picture and lets you decide.
The pull of a quick answer
It is worth being honest about why fast, frictionless online assessment is appealing, and why that appeal can lead people astray. When you have spent years feeling that something is wrong and finally found a possible explanation, the urge to get an answer quickly is completely understandable. But ADHD is also a condition where there is real debate about recognition and rates, which we explore in is ADHD overdiagnosed. A rushed or superficial assessment serves nobody, least of all you, because a diagnosis built on thin ground can be questioned later and may not get you the support you actually need. The thoroughness is the point.
Practical signs of a good service
Pulling it together, a reputable online ADHD assessment service will be CQC-registered, clear about who is assessing you and their qualifications, and following the NICE-recognised process of clinical interview plus developmental history. It will explain what happens after diagnosis, be honest about shared care and GP acceptance, and price the whole thing transparently without pressure. The NHS overview of ADHD is a useful reference point for understanding what diagnosis and treatment should involve before you start comparing providers.
What this means in practice
- Check the provider is CQC-registered before you book. Look them up directly on the CQC site.
- Ask who will assess you, their qualifications, and their professional registration.
- Confirm the assessment includes a full clinical interview and developmental history, not just a questionnaire.
- Find out what happens after diagnosis, including who handles medication and follow-up.
- Be wary of pressure to book fast, vague answers about responsibility, or hidden costs.
- Ask whether you receive a full written report, and what it contains. A proper report is part of what you are paying for.
Online assessment has made getting answers about ADHD far more accessible, and that is a real gain. The responsibility that comes with it is doing a little homework on who you trust with the diagnosis. If you are weighing up your options, you can start with a private ADHD assessment and check our appointments information to see how the process works. A good assessment is worth waiting and choosing carefully for.
