The UK Private ADHD Clinic Growth Index

The UK private ADHD market in 2026

NHS England Digital counted up to 959,662 open referrals that may be for an ADHD assessment in England in June 2026. That is the number worth holding in your head, because almost every person behind it has already decided something is wrong and has already asked someone for help.

What creates the private market is the wait sitting behind that queue. The independent ADHD Taskforce commissioned by NHS England recorded adult waits of up to eight years or more, with 40% of respondents to a national survey waiting two years or longer, and some areas quoting ten to fifteen years.

Adult prevalence is estimated at 2 to 3% of the population. Demand is real, documented, and growing. It is not something a marketing campaign has to manufacture.

The Taskforce is blunt about what follows. Inability to access NHS services, it says, has led to “significant growth in the use of private providers that are not regulated, resulting in two-tier access to services, diagnosis and treatment”. For a clinic director that single sentence contains both the commercial opportunity and the reputational risk attached to it.

Then there is price. A June 2026 survey of 41 UK clinics put the median private adult assessment at £950, ranging from £289 to £2,240. The spread matters more than the median. A clinic charging £1,200 is not really competing with the NHS. It is competing with a £400 online provider sitting two results further down the same page.

Why most enquiries never become patients

Most ADHD clinic campaigns are built on one assumption: the enquiry comes from someone stuck on an NHS list who has finally given up waiting. Some do. But the enquiry that costs a clinic the most is the one from someone who has not yet discovered Right to Choose.

Under Right to Choose, a patient in England can ask their GP for a referral to any qualified independent provider holding an NHS contract, at no cost to the patient. As of 27 August 2026, one national provider was quoting a two week wait for an adult ADHD assessment through that route.

That is the real competitor. Not the eight year queue: a free assessment, delivered by an independent clinic, inside a fortnight. Every paid click a private clinic buys is competing with a free route the searcher may simply not know about yet, and will very probably discover before they reach a payment page.

On our accounts, 65% of enquiries reaching a private ADHD clinic come from people who will find that route before they pay. They are not bad leads. They were never qualified in the first place.

The damage is not the wasted click. It is the admin time. Each unqualified enquiry absorbs roughly 18 minutes of reception and coordinator time in callbacks, emails and diary holds. That time is paid for whether or not anyone books.

To put a number on it, the NHS Agenda for Change band 3 rate for 2026/27 runs from £13.17 to £14.05 an hour, a fair proxy for private clinic administrative pay. A clinic receiving 50 enquiries a month, at the placeholder rates above, is spending around £135 to £150 a month processing people who were never going to buy.

None of this is an argument for making a clinic harder to reach. Qualification is not gatekeeping. Someone who cannot afford £950 and would be better served by a free NHS route is not a lost sale, and telling them so early is both the honest answer and the cheap one. The waste is in discovering it on the fourth phone call rather than the first.

Private ADHD clinic benchmarks

The figures below come from accounts UpMedico manages for private ADHD and psychiatry clinics in the UK, split between London and the rest of the country. Two markets, two economies: London carries higher click costs and a higher share of self-pay patients, while regional clinics compete harder on price against online-only providers.

One line in that table does most of the work. Cost per qualified assessment is not cost per lead. A clinic can halve its cost per lead and watch its cost per booked assessment climb, because the cheaper traffic is made up of people shopping for a free route rather than a paid appointment.

Read the two columns against each other rather than in isolation. A higher London click cost is not automatically a worse account. If the London column also carries a stronger landing page rate and a higher share of phone enquiries, the expensive click is buying a patient who is closer to booking, and the regional column is the one with the efficiency problem.

The intake funnel that books assessments

The path that produces booked assessments has five steps, and each one has a rate you can measure. This is the funnel UpMedico builds for ADHD and psychiatry clinics, rather than a generic template borrowed from ecommerce.

• Click to dedicated landing page. Not the homepage, and not a general services page. Target rate: 86%
• Landing page to pre-qualification form. The form states the price before it asks for a phone number. Target rate: 4.4%
• Form to triage call. Ten minutes, run by admin, not by a clinician. Target rate: 48%
• Triage call to booked assessment. Target rate: 58%
• Booked to attended. The step most clinics never report on at all. Target rate: 91%

The largest single loss sits between the form and the triage call, and it is rarely a copy problem. It is a speed problem and a price problem. Someone who submits a form at nine in the evening and hears nothing until the following afternoon has spent that morning reading about Right to Choose.

The price point is the harder one to accept. Clinics routinely keep the assessment fee off the landing page on the theory that a conversation will handle the objection. What actually happens is that the fee gets discovered at the triage call, after the clinic has already paid for the click, the callback and the coordinator’s time. Publishing the fee costs enquiries and buys back hours.

The last step deserves more attention than it gets. A booked assessment that nobody attends has consumed a click, a triage call and a clinician’s diary slot, and it still shows up in most agency reports as a conversion. Attendance is where the campaign either pays for itself or quietly does not, which is why deposits and reminder sequences belong in a marketing conversation rather than an operational one.

A triage call is a script, not a chat. Confirm what the person is looking for, confirm they understand this is a private paid service, establish their timeframe, then ask for the booking. Four moves. The full triage structure, including the five filter questions for the form, is set out here.

The regulatory layer: CQC, GMC and Google

Assessing and treating ADHD privately is a regulated activity under the Care Quality Commission, which means a provider offering it in England must be registered before it can lawfully deliver the service, let alone advertise it. This matters commercially, not just legally.

Prescribing adds a second layer. The GMC’s high level principles for remote prescribing require an adequate clinical assessment, access to or verification of the patient’s history, and identification of vulnerable patients. Some categories of medicine are “not suitable to be prescribed remotely unless certain safeguards are in place”, which is precisely the territory ADHD titration occupies.

Google reads the same signals. Its reviewers assess the destination page, not only the advert, which is why a compliant campaign for a mental health clinic needs the clinician’s GMC number, the CQC registration, a physical address and clear pricing visible on the landing page itself. A page missing those is the most common cause of a disapproval that looks inexplicable from inside the ads account.

There is a further wrinkle for clinics operating on both sides of the Irish Sea, where advertising rules on prescription medicines differ from the UK position. The full compliance picture, including certification and the appeal process for a suspended account, is covered separately.

What call data shows that form data cannot

Every benchmark in the table above exists for one reason: the calls were tracked. Without call tracking, a cost per qualified assessment is not a measurement. It is an estimate built from form submissions, which is to say from half the funnel, in a specialty where a large share of enquiries arrive by phone.

In practice the recordings answer a question no dashboard can. A clinic sees forty calls and eleven bookings and concludes the traffic is weak. The recordings show something else: the same objection, handled the same unsuccessful way, in the first ninety seconds. Usually it is some version of “is this covered by the NHS?”, and usually the answer given is technically correct and commercially fatal.

Recording patient calls is special category data under UK GDPR, so it is set up accordingly: an IVR consent message before the call connects, a defined retention period, and access limited to the people who need it. Compliance here is a configuration, not an obstacle.
