Does a cheaper ADHD assessment mean lower quality?
Not necessarily. The price of a private ADHD assessment is driven by several practical factors — not solely the quality of the clinician or the outcome. Understanding what drives cost helps you find a genuinely affordable assessment without compromising on clinical rigour.
The single biggest cost driver is format. Online assessments are consistently cheaper than in-person equivalents because providers do not need dedicated clinical space for every patient. An online appointment with a specialist ADHD nurse at a well-regarded CQC-registered clinic will typically cost £200–£400 less than an in-person appointment with a consultant psychiatrist at a London clinic — yet both can produce a legally and clinically valid diagnosis.
Clinician type also affects price. Assessments led by consultant psychiatrists cost more than those conducted by specialist ADHD nurses or psychologists. In most cases, a nurse-led assessment is sufficient for diagnosis and to initiate medication through shared care. However, if you have a complex presentation — co-occurring conditions, a disputed previous diagnosis, or requirements for a specific type of report — a psychiatrist-led assessment may be worth the additional cost.
Location matters for in-person appointments. London and South East clinics charge a significant premium. If you are willing to travel, or to attend online, you can access equivalent-quality assessments for substantially less. Many people in London use online providers based elsewhere in England and save several hundred pounds.
What to check before booking a cheaper assessment
- →CQC registration: Confirm the provider appears on the CQC register. Any legitimate UK ADHD assessment clinic should be registered.
- →What's included in the price: Some providers quote a low headline price but charge separately for the written report, GP letter, or follow-up appointment. Confirm the full cost upfront.
- →Report acceptance: If you need the report for a specific purpose — prescribing, workplace adjustments, DSA, or insurance — check in advance that the provider's report format will be accepted.
- →Prescribing pathway: Check whether the clinic can initiate a private prescription and whether your GP accepts shared care from that provider. Some GPs have a list of preferred providers.
Frequently asked questions
What is the cheapest ADHD assessment in the UK?
The cheapest private ADHD assessments in the UK currently start from around £495 for an online adult assessment. Prices vary by provider, location, and what is included. Online-only assessments are consistently cheaper than in-person equivalents. If you are registered with a GP in England, you may also be eligible for a completely free assessment through the NHS Right to Choose scheme — which is the most cost-effective option if you can wait 6–18 months.
Are cheap ADHD assessments legitimate?
A lower price does not mean a lower-quality assessment, provided the provider is CQC-registered. CQC registration requires that clinicians meet specific qualifications, follow NICE guidelines, and undergo regular inspection. All providers listed on this page are CQC-registered. The main difference at lower price points is usually the length of the appointment, whether a full written report is included, and how much follow-up support is provided — not the clinical validity of the diagnosis itself.
What should be included in an ADHD assessment?
A complete ADHD assessment should include: a structured clinical interview covering your current symptoms, childhood history, and daily functioning; validated rating scales (such as the DIVA-5 or Conners); a written diagnostic report you can share with your GP; and a GP letter summarising the findings and any medication recommendations. Some lower-cost assessments charge separately for the report or follow-up appointment — always confirm what is included before booking. Also check whether the report will be accepted for prescribing, workplace adjustments, and DSA (Disabled Students Allowance) if relevant.
