One of the most common questions people ask is whether you can get an ADHD assessment without a GP referral. The short answer is yes, if you choose a private self-pay assessment. The route you take determines whether a referral is needed, and this guide explains exactly when you do and do not need one in the UK.
When you do not need a GP referral
With a private self-pay assessment, you can usually self-refer and book directly, with no GP letter required. This is one of the main reasons private assessment is so much quicker than the NHS route. At ADHD Diagnosis UK, for example, you can book an adult ADHD assessment online from £189 without any referral, and have your assessment by video with a GMC-registered doctor, with a written report provided the next day.
When you do need a referral
If you want an NHS-funded assessment, whether through your local NHS service or through NHS Right to Choose, you will need a GP referral. Your GP reviews your symptoms and, if they agree an assessment is appropriate, makes the referral. You can read more in our guide to NHS Right to Choose for ADHD.
Why does private assessment skip the referral?
Because you are paying directly for the service rather than asking the NHS to fund it, there is no need for a GP to act as a funding gatekeeper. A reputable private provider will still carry out a full clinical assessment to recognised standards, and a good clinician will always consider whether something other than ADHD might better explain your symptoms. Skipping the referral speeds up access; it does not mean a lighter assessment.
What about medication and your GP afterwards?
Even if you self-refer for the assessment, your GP can still be involved afterwards. If medication is recommended, some GPs will enter a shared-care arrangement to continue prescribing, although this is at their discretion. It is sensible to ask your GP about their shared-care policy before you start, so you know what to expect. Medication itself is paid for separately at the pharmacy.
How to book without a referral
The process is simple. You choose your assessment, complete the pre-assessment information and questionnaires, attend a secure video appointment, and receive your report. There is no waiting for a GP letter and no waiting on a list. See our step-by-step guide to the online assessment or our pricing page for full details.
Frequently asked questions
Can I really book a private ADHD assessment myself?
Yes. With a private self-pay provider you can self-refer and book directly online, with no GP referral needed.
Is a self-referred assessment still valid?
Yes. A diagnosis made by a suitably qualified clinician using recognised standards is a genuine clinical diagnosis, whether or not a GP made the referral.
Will I still need my GP at all?
Possibly, for ongoing prescribing under shared care if medication is recommended. Ask your GP about their policy in advance.
No referral, no waiting list. Book your online adult ADHD assessment from £189 with a next-day written report.
