Adult ADHD assessment · United Kingdom

Four ways to an ADHD assessment in the UK, side by side.

NHS, Right to Choose, a private psychiatrist or a specialist ADHD clinic. What each route involves, what it costs, how long it takes, and what to ask before you book.

Medically reviewed by Dr Kunal Choudhary, Consultant Psychiatrist · Updated October 2026 · 6 minute read

1 · What happens in an assessment

From forms to a clear answer, step by step.

ADHD starts in childhood, so a proper assessment looks at your whole life, not just this month. Here’s what that looks like at a specialist-led clinic like ours. Other routes cover the same ground, often over more visits.

Step 1 · At home


Four forms in the app. Plus two people who know you

Step 2 · By video


The clinical interview. About 90 minutes with a specialist assessor

Step 3 · In writing


Your outcome letter. Outcome letter within 10 working days

Step 1 · Before your interview

Four short forms in the app. Try them.

Your clinician reads everything before they meet you, so the interview can go deeper. Save and come back any time. Tap through a sample below.

No one who knew you as a child? There’s another route, and it doesn’t stop you being assessed. See how ↓

Step 2 · The clinical interview

About 90 minutes, by video, all about you.

Not a test, nothing to pass or fail. Your clinician has read your forms, so the time goes on the detail. Real examples help most: the half-finished tasks, the missed appointments, the things people have said about you for years.

Clinical interview · by video

1

Why you’re here

What brought you, and what you most want help with.

2

How ADHD shows up today

Focus, restlessness, organisation and emotions, with real examples from work, home and relationships.

3

Childhood and school

What you were like before 12, what reports said, and what your informants described.

4

The rest of the picture

Mood, anxiety, sleep, alcohol, physical health and family history, to rule other things out.

5

Where things stand

Your clinician shares their thinking and what happens next.

Set up

A quiet spot, a decent connection and your camera on. Phone, tablet or laptop all work.

Bring someone

A partner or family member is welcome to join, and breaks are fine whenever you need one.

Behind your clinician

A consultant psychiatrist reviews every diagnosis before your outcome letter is signed off.

DSM-5

Every assessment is measured against the DSM-5 criteria for ADHD, in line with NICE guideline NG87, the UK standard for adult ADHD.

Step 3 · Your outcome

A clear answer, then the full picture in writing.

Your assessor shares their thinking at the end of your interview. A consultant psychiatrist then reviews the diagnosis, and your outcome letter follows within 10 working days. With your consent, we send it to your GP too.

What’s inside

✓

Outcome

Adult ADHD, and the presentation that fits you.

✓

The reasoning

How everything we looked at meets the DSM-5 criteria, in plain English.

✓

What we looked at

Your four forms, two informant reports and your clinical interview.

✓

Recommendations

Recommended next steps, which may include treatment options.

Example. Your report is written about you.

Six things every good assessment includes

Based on the DSM-5 and standard assessment practice

✓

Your story from childhood. ADHD starts before 12, so a good assessment looks back, not just at today.

✓

Someone who knows you. A parent, partner or friend adds what you can’t see yourself.

✓

Standard rating scales. Recognised questionnaires, scored the same way for everyone.

✓

Ruling other things out. Anxiety, low mood, sleep, alcohol and physical health can look like ADHD.

✓

A registered clinician. With real ADHD experience, on the GMC or NMC register.

✓

A written report. The outcome and the reasoning, not just a yes or no.

Whichever route you choose, if a provider skips any of these, ask why.

2 · Your options in the UK

Four ways in. Side by side.

Choose what matters most to you and we’ll highlight it across every route.

Free

NHS, via your GP

Wait for an assessment

Often over a year, varies by area

Typical cost

Free

Who assesses you

An NHS specialist team

Team behind them

Yes, an NHS team

ADHD training

Yes, from your GP

Wait to start medication

A second wait for titration, up to 2 years in some areas

Best if

You can wait, and want it free.

England only

NHS Right to Choose

Wait for an assessment

Can be quick, but some providers have waits of up to 2 years

Typical cost

An NHS-contracted provider

Team behind them

Varies by provider

GP referral

Yes, your GP must agree to refer

Wait to start medication

Best if

You live in England, your GP will refer you, and you can wait for titration.

Wait to start medication

Varies a lot. Ask how soon you see a prescriber

Best if

You want to start soon, from home, at a known price.

Where ADHD Simple sits

Watch the second wait. On the NHS and Right to Choose, a fast assessment can still mean a long wait for medication. Funding for assessments is often available, but titration places are capped in many areas, so starting medication can be up to 2 years away.

3 · Shared care, in short

After a private diagnosis, shared care decides what you pay for medication.

What it is

Once a specialist has found your dose, your GP takes over prescribing and you pay NHS prescription charges. The specialist still reviews you, usually once a year.

It isn’t guaranteed

It’s voluntary. The work is often unfunded, the medication comes out of local NHS budgets, and some ICBs tell practices not to accept it from private providers. Ask your practice before you go private.

At ADHD Simple

79%

of our shared-care requests have been accepted. If yours says no, nothing changes: you stay with us.

4 · Specialist, without the wait or the cost

Specialist involvement, without the wait or the cost.

Most routes make you trade something away: a specialist, a short wait, or an affordable price. A specialist ADHD clinic with a consultant psychiatrist reviewing every diagnosis means you don’t have to.

40 full-time clinicians across our team · 4,000+ assessments · By video from anywhere in the UK

5 · After your diagnosis

The whole journey, and what it really costs.

Watch for a cheap assessment with expensive aftercare. Many clinics price the assessment low, then charge a monthly membership and high-street medication prices for years. The assessment is the first step, not the last. Here’s every step with ADHD Simple: how long each one takes and what you pay, before you book anything.

Today

Book and do your forms

No GP referral. Forms in the app, and two people who know you.

Prefer to talk it through first? Call 0118 230 0004 or message us on WhatsApp.

6 · Questions to ask

Ask any provider these six. Including us.

1

“Is every cost broken out, including after diagnosis?”

Assessment, prescriber reviews, ongoing care and medication can add up. Ask for the total, not just the first price.

4

“Do you have a medication pathway?”

A psychologist can diagnose ADHD but can’t prescribe, so you may need a second assessment somewhere else.

2

“What happens if my GP won’t agree to shared care?”

Shared care is your GP’s decision, and some say no after a private diagnosis. Ask what happens to your medication, and what it costs, if yours does.

5

“Who assesses me, and how were they trained in ADHD?”

ADHD training varies a lot. Look for specific ADHD training and registration with the GMC or NMC.

3

“How long until I’m seen, and until I could start medication?”

A quick assessment means little if there’s a second wait for a prescriber. Ask about both.

6

“Will you accept a diagnosis I already have?”

Some clinics make you pay for a new assessment. Others review your existing report first.

7 · Which suits you

Three taps to your best-fit route.

How soon do you want answers?

Where ADHD Simple sits

Psychologist or psychiatrist?

It comes down to one question: might you want medication?

A psychologist can diagnose ADHD, but can’t prescribe. That makes a psychologist a good pathway for some people, and a detour for others.

A psychologist suits you if

✓

You’re sure you don’t want medication

✓

You mainly want to understand how your brain works

✓

You’d like therapy or practical strategies alongside

A prescribing team suits you if

✓

You might want medication, now or later

✓

You don’t want a second assessment and another wait

✓

You want one team from diagnosis to the right dose

A medication pathway built in. At ADHD Simple, medication is never assumed. But if you’re diagnosed and it’s right for you, the same team starts it and helps you find the right dose. No second assessment, no new list.

6 · Questions to ask

Ask any provider these eight. Including us.

Ask any provider these eight. Including us.

1

“Do I need a GP referral first?”

Getting a GP appointment and a referral can add weeks before you’re even on a list.

5

“Do you have a medication pathway?”

A psychologist can diagnose ADHD but can’t start medication, so you may need a second assessment somewhere else.

2

“How long are the waits, for the assessment and for care after it?”

A quick assessment means little if there’s a second wait to start treatment. Ask about both.

6

“Is every cost broken out up front?”

Assessment, medication reviews, extra appointments and ongoing care can add up. Ask for every price before you start.

3

“Who assesses me, and how were they trained in ADHD?”

ADHD training varies a lot between clinicians. Look for specific ADHD training and people who do it every day.

7

“Can my GP and pharmacist act on the report?”

A good report is detailed enough for other clinicians to continue your care without starting again.

4

“Is there a team behind them?”

A clinician working alone may need to refer you on for complex questions, with a new wait.

8

“Who sees my report?”

Your health information should be yours to share.
