Information checked: 23 August 2026

This is an independent desk-based review of waiting-time information published online by ten organisations offering NHS Right to Choose ADHD services in England. Pryhelm did not telephone providers, pose as a patient or independently verify appointment availability. Waiting times can change quickly and may be affected by age, location, clinical suitability and local NHS arrangements.

NHS Right to Choose ADHD Wait Times in England: August 2026 Audit

If you search for current NHS Right to Choose ADHD waiting times, you might expect to find a straightforward list. Instead, you are likely to encounter a confusing mixture of weeks, months, regional warnings, referral-processing periods and separate medication queues.

One service may describe the time from the original GP referral. Another may begin measuring only after every questionnaire has been returned and approved. Some publish separate estimates for adults and children, while others provide a general figure that may not apply equally across England.

The greatest source of confusion is the distinction between receiving an ADHD assessment and beginning treatment. A provider may be able to offer an initial assessment relatively quickly but have a substantially longer waiting list for medication titration.

To understand what patients are actually being told online, Pryhelm reviewed the public waiting-time information supplied by ten organisations offering ADHD services through NHS Right to Choose. We examined assessment estimates, medication waits, age restrictions, referral processing and regional differences.

The providers have not been named in this article. Our purpose is not to rank individual organisations or evaluate their clinical quality. Instead, this audit examines the wider information available to patients and identifies the questions people should ask before selecting a service.

Key findings from the August 2026 review

Finding	What we found
Shortest published adult estimate	Around 1–2 weeks after the required referral information or forms had been received
Longest published estimate	Up to approximately 2 years in some pathways or local NHS areas
Common middle range	Several published estimates fell between approximately 12 and 20 weeks
Longest separate medication estimate	Approximately 56 weeks after assessment on one published pathway
Medication transparency	Fewer than half of the services reviewed displayed a clearly usable numerical medication or titration estimate
Regional variation	Several services warned that waiting times could differ substantially according to the patient’s Integrated Care Board area
Adult and child differences	Some organisations offered adult services only, while others published much longer estimates for children than for adults

These figures describe information visible on provider websites when reviewed on 23 August 2026. They are not guaranteed appointment times and should not be used as a substitute for checking current availability.

The headline waiting time may not tell the whole story

The most attractive figure found during our review was an adult assessment estimate of around one to two weeks. At the opposite end of the range, some published pathways warned that patients could wait up to approximately two years.

That is an enormous difference, but it is not necessarily a direct comparison.

A two-week estimate might begin only after the provider has received and accepted the referral, questionnaires, medical information and any required supporting evidence. It may refer to the first assessment appointment rather than the completion of the entire diagnostic process.

A longer estimate might be measured from the day the GP first submits the referral. Some providers also incorporate local funding restrictions into their estimates, while others publish their standard national position separately.

Patients should therefore be cautious about interpreting a short number as a promise. Before requesting a referral, it is worth asking exactly when the provider starts its waiting-time clock and which stage marks its end.

Assessment and medication are separate stages

The clearest finding from this review was that assessment waiting times and treatment waiting times should never be treated as interchangeable.

An ADHD assessment is the clinical process used to decide whether a person meets the relevant diagnostic criteria. Medication titration is a later process in which a qualified professional starts an appropriate medicine, monitors its effects and gradually adjusts the dose where necessary.

Not everyone diagnosed with ADHD will want medication, and medication will not be clinically suitable for every person. Nevertheless, people who hope to explore it need to understand that receiving a diagnosis may place them at the beginning of another queue.

Among the services reviewed, published medication estimates included ranges of approximately 8–12 weeks, 25–40 weeks, 8–10 months and, on one pathway, around 56 weeks.

In practical terms, a person might receive an assessment within a month but wait much longer before medication can begin. Someone choosing a service purely because it displays the shortest assessment time may therefore find that the complete pathway is not the shortest.

NICE guidance on ADHD diagnosis and management states that ADHD medication should be initiated by a healthcare professional with appropriate training and expertise. It cannot simply be started without specialist clinical consideration and monitoring.

Why postcode can affect the answer

Right to Choose providers are often described as national services, especially where assessments are conducted online. However, that does not always mean every patient receives the same waiting time.

Several organisations reviewed in August 2026 warned that their capacity was affected by arrangements set by local Integrated Care Boards. An Integrated Care Board, commonly called an ICB, plans and funds many NHS services for people living in its area.

Where an ICB sets a limit on the number of assessments a provider can deliver, referrals may continue to accumulate even if the provider has clinicians available. This can create a situation in which patients selecting the same organisation receive very different estimates depending on where their GP is registered.

Some published standard estimates were approximately four to five months, yet accompanying regional information warned of waits of 78 weeks, two years or even longer in certain areas.

A patient in London may therefore receive a different answer from somebody in Manchester, Birmingham, Kent, Devon or Norfolk. This regional variation is one of the main reasons an undated national comparison can become misleading.

Right to Choose applies to England—not the whole UK

Although people frequently search online for “UK Right to Choose ADHD waiting times”, the pathway described here applies principally to NHS patients in England.

The NHS guidance on patient choice explains that when a GP needs to refer someone for a physical or mental health condition, the patient will in many cases have a legal right to choose the hospital or service they wish to attend.

The choice can include an independent organisation where it supplies the relevant service to the NHS. However, this does not mean that any private ADHD clinic can be selected. The organisation must hold an appropriate NHS contract for the service being requested.

The detailed NHS Choice Framework also explains that these choices apply at the point of referral and are subject to certain exceptions.

Patients registered in Wales, Scotland or Northern Ireland do not have an identical Right to Choose entitlement. Someone living in Cardiff, Swansea, Edinburgh or Belfast should ask their GP about the referral options available within their own health service.

Why children may wait longer than adults

Adult and child figures should not be combined into a single ADHD waiting-time estimate.

During this review, some organisations accepted adults only. Others accepted both adults and children but operated different pathways for each group. In one published example, the adult assessment estimate was measured in weeks while the child estimate was approximately eight months.

Assessing a child commonly involves gathering information from parents, carers and school. Teachers or special educational needs staff may need to complete questionnaires describing the child’s attention, behaviour and functioning in an educational setting.

Age thresholds also varied. Some services accepted children from around seven or eight years old, while others maintained separate under-18 websites or services.

Parents should check:

• the provider’s minimum age;
• whether the service assesses children or adults only;
• whether school information is compulsory;
• whether appointments are online or in person;
• whether the child is clinically suitable for remote assessment; and
• whether medication and continuing care are included after diagnosis.

What does “waiting for assessment” actually mean?

One reason comparisons are difficult is that providers do not always measure the same period. A published waiting time may begin:

• when the GP sends the referral;
• when the provider receives it;
• when the provider confirms eligibility;
• when screening documents are returned;
• when supporting information is complete; or
• when the patient is considered “assessment ready”.

The finishing point can also differ. It might refer to the first appointment, the main diagnostic interview, the feedback appointment or completion of the written report.

This matters because referral processing itself can take several weeks. A provider advertising a 12-week assessment queue might also require additional time to check the referral and gather documents before the patient formally joins that queue.

A more meaningful estimate would state:

The estimated time from the date we receive a complete GP referral to the patient’s first ADHD assessment appointment is approximately X weeks.

Without that level of detail, apparently precise waiting times can create false certainty.

Five questions to ask before choosing a service

1. Does this estimate apply in my ICB area? Ask whether your postcode or GP location changes the published waiting time.
2. When does the waiting time begin? Confirm whether the clock starts with the GP referral or only after every form has been returned and approved.
3. What stage does the estimate cover? Find out whether it means the first appointment, the completed assessment or receipt of the diagnostic report.
4. What is the separate medication wait? If medication might be important to you, request the current titration estimate rather than assuming it is included.
5. Who will provide continuing prescriptions and reviews? Ask whether the specialist retains responsibility or expects your GP to accept a shared-care arrangement.

How to request a Right to Choose referral

First, identify a provider currently offering the NHS service you require. Check whether it covers your age group and whether any local restrictions apply.

Many providers supply a downloadable GP letter, screening questionnaire and referral form. Completing the relevant documents before seeing your GP may make the process easier, although the GP will still need to decide whether a specialist referral is clinically appropriate.

At your appointment, explain the difficulties you have been experiencing and why you would like an ADHD assessment. Tell the GP if you wish to discuss referral to a particular eligible provider under NHS Right to Choose.

Before assuming the referral has been completed, confirm:

• the name of the selected service;
• the address or email used for the referral;
• whether all required questionnaires were attached;
• whether a summary care record was included;
• how the provider confirms receipt; and
• when it would be reasonable to follow up.

Incomplete paperwork can create a delay before the published waiting period even begins.

Methodology

Pryhelm conducted this desk-based audit on 23 August 2026. We reviewed publicly accessible information from ten organisations offering NHS Right to Choose ADHD services in England.

We looked for:

• a numerical adult or child ADHD assessment estimate;
• a separate medication or titration estimate;
• the point from which the wait was measured;
• adult and child eligibility;
• regional or ICB restrictions;
• referral-processing information; and
• whether treatment was available after diagnosis.

The results have been aggregated. Individual organisations have not been identified or ranked because this article is intended to examine the accessibility and consistency of public waiting-time information rather than assess particular providers.

No telephone calls were made and no mystery-shopping exercise was conducted. We did not test actual appointment availability or evaluate the quality of clinical care.

Limitations

This review represents a single point in time. Waiting lists can change quickly, and provider webpages may be updated after publication.

The estimates were not independently verified against appointment records. We could not establish whether every organisation calculated its figures in the same way. Nor could we determine how long a particular patient would wait after clinical screening and application of local NHS requirements.

The shortest published estimate should not be interpreted as evidence of the best clinical service. This audit did not examine diagnostic quality, patient outcomes, clinician qualifications, regulatory history, complaints or patient satisfaction.

Frequently asked questions

What was the shortest ADHD assessment estimate found?

The shortest adult estimate found during the review was approximately one to two weeks after the required information or forms had been received. It was an estimate rather than a guaranteed appointment time.

What was the longest estimate found?

Some pathways or regional notices indicated waits of approximately two years or longer. Local ICB arrangements appeared to be an important reason for some of the longest estimates.

Is Right to Choose ADHD assessment free?

An eligible referral accepted through the NHS Right to Choose pathway is NHS-funded. Patients should ensure they are following the provider’s NHS route rather than booking its separate self-funded service.

Can I use Right to Choose in Wales?

Not in the same way as a patient registered with an English GP. Wales, Scotland and Northern Ireland have different health systems and referral arrangements.

Does an ADHD diagnosis guarantee medication?

No. Treatment is based on individual needs, preferences, medical history and clinical suitability. Medication is one possible treatment and requires appropriate specialist oversight.

Can my GP refuse shared care?

A shared-care arrangement requires agreement between the specialist and GP. Patients should ask the chosen service who will continue prescribing if their GP does not accept shared care.

What patients should take from this audit

The difference between the shortest and longest published estimates was striking, but the numbers alone did not provide the complete picture.

A short assessment queue can be followed by a long medication queue. A national estimate may not apply in every ICB area. An adult pathway may be much quicker than the corresponding child service. A waiting period may not begin until several forms have been completed and checked.

For patients and families, the most useful approach is to compare the complete journey rather than a single headline figure:

1. GP referral and processing;
2. clinical screening and acceptance;
3. ADHD assessment;
4. feedback and diagnostic report;
5. medication titration, if appropriate; and
6. continuing prescribing and clinical reviews.

Right to Choose can provide valuable alternatives to a local waiting list, but informed choice requires information that is current, clearly dated and measured consistently.

When comparing services, check the date, confirm the starting point, ask about your local area and look beyond the assessment wait to what happens after diagnosis.
