How to Get an ADHD Assessment Faster in the UK: Practical Ways to Cut the Wait

The Right to Choose is the single most effective way to get an NHS-funded ADHD assessment faster. Under NHS England rules, you have the legal right to choose which provider carries out your assessment, as long as they hold an NHS contract. Several providers - such as Psychiatry-UK and Clinical Partners - offer ADHD assessments under Right to Choose with significantly shorter waits than most local NHS services.

To use Right to Choose, you need your GP to make a referral. Some GPs are familiar with the process and will refer without difficulty. Others may be less aware of it. If your GP is hesitant, our guide to asking your GP for an ADHD assessment explains how to approach the conversation, including what to say if they push back.

A private assessment is the fastest option, with some providers offering appointments within days or weeks. Costs typically range from around 500 to 1,200 pounds depending on the provider, format, and whether post-diagnosis support is included. Our ADHD assessment cost guide compares what different providers charge.

Going private does not mean you leave the NHS behind. A private diagnosis is valid and should be accepted by your GP for ongoing prescribing through shared care, though some GPs are more cooperative than others. If you can afford the upfront cost, private assessment followed by NHS shared care for medication is a common and practical route that many adults in the UK now take.

A small number of charitable organisations offer subsidised ADHD assessments for people who cannot afford private fees. Availability is limited and varies by region, but it is worth checking. ADHD UK and other ADHD charities sometimes maintain lists of lower-cost options or hardship funds.

Some universities also offer assessments for students through their disability services, which can be faster than the general NHS pathway. If you are currently studying, ask your university's student wellbeing or disability team whether they can arrange an ADHD assessment or fund a private one.

Going to A&E will not get you an ADHD assessment. ADHD is not treated as an emergency condition and emergency departments are not equipped to diagnose it. Self-referring to most NHS ADHD services is also not possible - you almost always need a GP referral.

Repeatedly calling your GP surgery about your place on the waiting list will not speed things up. The wait is a capacity issue at the specialist service, not something your GP controls. Your energy is better spent exploring the alternative routes above.

Completing a validated ADHD screening questionnaire before your GP appointment can make the conversation more productive. The ASRS (Adult ADHD Self-Report Scale) is widely used and freely available online. Bringing a completed copy shows your GP that you have thought carefully about your symptoms and gives them a structured starting point.

Screening tools do not diagnose ADHD, but a high score on the ASRS makes it harder for a GP to dismiss your concerns. Combined with specific examples of how ADHD symptoms affect your daily life, a screening result turns a vague "I think I might have ADHD" into a clear clinical case for referral.

Yes - video-based ADHD assessments are clinically valid and widely used across NHS and private services. Psychiatry-UK, the largest Right to Choose ADHD provider, conducts most of its assessments online. NICE guidelines do not require face-to-face assessment specifically.

The key is that the assessment is carried out by a qualified clinician - a psychiatrist, specialist nurse prescriber, or clinical psychologist with ADHD training. The platform matters less than the person doing the assessment. Be cautious of services that offer a diagnosis based solely on questionnaires without a live clinical interview, as these may not be accepted by GPs.
