The short answer

There are three routes to an ADHD assessment in the UK: a referral to your local NHS service, an NHS-funded Right to Choose referral to an independent provider (England only), or paying for a private assessment yourself. Start by taking a short history of lifelong difficulties and current impact to your GP. The main routes are a local NHS referral, an NHS-funded Right to Choose referral in England, or a private self-referral. An assessment should examine childhood history, difficulties across settings, functional impact, coexisting conditions and other possible explanations — not just a questionnaire score.

01

Route one: standard NHS referral

Book a GP appointment, describe how the pattern has affected more than one part of life, and ask what the local adult or child referral route requires. Bring a one-page timeline with childhood examples, current examples and the practical impact; a screening questionnaire can support the conversation but cannot diagnose ADHD.

There is no honest national waiting-time figure. Local services and criteria differ and change, so ask your GP which service receives the referral and check that service's current information. Support for sleep, mood, work or school does not need to wait for an ADHD decision.

02

Route two: Right to Choose (England only)

In England, eligible first outpatient referrals may use NHS Right to Choose. Your GP makes the NHS-funded referral to an eligible provider you choose; the route does not apply in Scotland, Wales or Northern Ireland.

Ask the provider for its current referral requirements, give those details to your GP, and ask the practice to confirm when the referral is sent. Provider status and waits change, so check them at the source rather than relying on an old comparison table.

03

Route three: private assessment

A private route usually allows self-referral and means paying for the assessment. Before booking, establish who assesses you, whether a written diagnostic report is included, and what separate charges may follow for medication appointments, prescriptions and reviews.

A private diagnosis does not guarantee NHS prescribing. If medication may be relevant, ask the provider how ongoing review works and ask your GP practice how it approaches shared-care requests before paying.

04

What the assessment involves

A qualified professional takes a developmental and clinical history, asks about symptoms and impairment in different settings, considers coexisting conditions and other explanations, and may use a structured diagnostic interview. A questionnaire is one input, not the assessment itself.

School reports and information from someone who knew you in childhood can help demonstrate early patterns. If they are unavailable, tell the service before the appointment and ask what other evidence it accepts rather than assuming the assessment cannot proceed.

05

Which route fits your situation

All three routes can end in the same thing: an assessment by a qualified professional and, where appropriate, a discussion about treatment. What differs is who pays, who chooses the provider, and how straightforward the medication and review arrangements are afterwards.

Where you live decides what is available. Right to Choose applies to eligible NHS referrals in England only; in Scotland, Wales and Northern Ireland the choice is between the local NHS route and paying privately. That is a fact about the route, not a judgement about which is better.

The practical question worth answering before you commit is not “which is fastest” — nobody can tell you that honestly — but “what happens after the diagnosis”. If medication may be relevant, ask each option how prescribing and reviews work, and ask your own GP practice how it handles shared-care requests. Our reading of the pathway, not a rule: this single question separates a route that ends well from one that leaves you paying indefinitely for reviews.

You do not have to pick one and abandon the others. Asking your GP about a local referral costs nothing while you look into the alternatives, and support for sleep, mood, work or school does not depend on the ADHD decision at all.

Work out your route

There are three assessment routes in the UK and two of them are NHS-funded. These tools help you work out which applies to you before you spend anything.

Questions

Common questions

01
How long is the NHS ADHD wait?
There is no reliable UK-wide answer. Ask which local service receives the referral and check its current information. In England, you can also check current Right to Choose information, but provider status and waits change and should be verified directly.
02
Will the NHS accept a private diagnosis?
The report and the prescribing decision are separate. An NHS clinician or GP may review the report, and ongoing NHS prescribing depends on local arrangements and an agreed shared-care request; it is not guaranteed by paying for an assessment.
03
Do I need school reports?
They help evidence childhood onset, but they are not mandatory. Family recollection, old reports, work history and your own account can all contribute.
04
How do I find an ADHD assessment near me?
Ask your GP which NHS service covers your address and what its referral criteria are. For private care, check the clinician's professional registration, assessment process, written report and follow-up arrangements rather than relying on distance or a directory listing.
05
Should I wait for the NHS or pay privately?
There is no general answer, and nobody can quote you a reliable wait. The question that does help is what happens after the diagnosis: ask each route how prescribing, titration and reviews work, and ask your GP practice how it approaches shared-care requests. Asking about an NHS referral does not stop you exploring a private assessment, and in England an eligible referral may also use Right to Choose.

Reviewed questions on this page

How do I get assessed for ADHD in the UK?
The usual starting point is a GP referral. In England, Right to Choose may offer an NHS-funded alternative provider; private self-referral is another route. Provider eligibility and waiting times change, so current details should be checked at source.Do thisPrepare one childhood example, examples from two current settings and one concrete effect on daily life for the GP conversation.What this does not settleA referral, questionnaire or self-check is not a diagnosis, and pathways differ across the UK.

Can I be assessed for ADHD and autism at the same time?
They are two assessments, arranged through two pathways, and how they are sequenced locally varies. Some services can consider both; many handle them separately. A GP is still the usual starting point for either, and it is reasonable to say plainly that you want both considered.Do thisAsk your GP one direct question: “Can this practice refer me for an ADHD assessment and an autism assessment, and does either go to the same service?” Then ask for the answer in writing.What this does not settleLocal arrangements, waiting times and whether one service covers both differ across the UK, and we cannot tell you what your area does. Right to Choose arrangements are also not identical for the two conditions.

Can my GP diagnose ADHD?

What happens in an ADHD assessment?
Expect a structured conversation about your development and current life, questions about difficulties across settings, consideration of other explanations, and often information from someone who knew you as a child.

Is it worth getting assessed in my forties or later?
That depends on what you want from it: an explanation, access to treatment options, or workplace and study support. Assessment can be worthwhile at any age, and recognition later in life is well described.Do thisDecide what you want the outcome to change — treatment options, workplace or study support, or simply an explanation — and say that when you ask your GP, because it shapes which route makes sense.What this does not settleAssessment can also conclude that something else fits better, which is a useful outcome rather than a failed one.

Do I need someone who knew me as a child?
An assessment looks at whether difficulties were present earlier in life, so information about childhood is useful — school reports, old reports cards, or an account from a parent or older sibling. Not having anyone available does not stop an assessment: clinicians work with your own history when other informants are not available.Do thisGather what you already have — school reports, work reviews, anything showing a long-running pattern — before the appointment.What this does not settleExactly what a service asks for varies between NHS and private providers. Nothing on this page determines whether you meet criteria.

How do I actually raise ADHD with my GP?
The appointment goes better when it is about difficulty rather than the label: two or three concrete examples of what goes wrong, roughly how long it has been that way, and what you are asking for — a referral discussion. A GP does not diagnose ADHD; the referral leads to a specialist assessment.Do thisTake a written page: three examples, how long the pattern has run, and the sentence “I would like to discuss a referral for an ADHD assessment.”What this does not settleLocal referral criteria and routes differ, and a GP may want to consider other explanations first. Our self-check is preparation only — it produces no score and no result.
