NHS vs Private Adult ADHD Assessment UK

The decision in one table

Waiting times and prices change. A route comparison should not present a fixed national average as if it applies to your referral.

Non-clinical ADHD mentoring can support routines while you wait or after an assessment. It cannot advise which clinical route is appropriate or diagnose ADHD.

What should be the same

Regardless of funding, NICE says ADHD diagnosis should only be made by a specialist psychiatrist, paediatrician or another appropriately qualified healthcare professional with relevant training and expertise.

The process should include:

• full clinical and psychosocial assessment
• developmental and psychiatric history
• behaviour and symptoms in different settings
• observer information where appropriate
• mental state
• impairment
• coexisting conditions and alternative explanations

No questionnaire alone can diagnose ADHD. NICE does not require one named assessment tool or set one universal appointment length.

The adult assessment guide explains the clinical process in more detail.

Local NHS route

The local NHS route has no assessment fee at the point of use. It may also provide NHS-funded treatment and follow-up if ADHD is diagnosed and treatment is clinically appropriate.

Advantages

• no private assessment or specialist-care fee
• care remains within the commissioned local pathway
• local prescribing and escalation responsibilities may be clearer

Questions and limitations

• waits may be several months or years
• referral thresholds and service scope differ
• assessment and medication may have separate queues
• support while waiting varies

Ask the service to confirm referral acceptance, current stage, treatment availability and contact details for changes in need.

NHS patient choice in England

Some ADHD services delivered remotely may fall within the legal right to choose a provider and team. This is commonly called Right to Choose.

It is not a right to select any private clinic. The referral must be clinically appropriate and the provider must meet the relevant NHS contract conditions. Exceptions apply.

Advantages

• NHS-funded for an eligible referral
• a choice of qualifying provider
• may offer a shorter wait than the local service

Questions and limitations

• England only
• provider eligibility and capacity can change
• assessment, medication and follow-up offers differ
• GP shared care is not guaranteed

Check the provider's current NHS pathway rather than its private-service description.

Private route

Private assessment provides the widest provider and appointment choice. It also transfers the financial and quality checks to the buyer.

Advantages

• potential access to an earlier appointment
• choice of clinician and format
• direct control over booking

Questions and limitations

• assessment, treatment and review fees
• variable assessment models and report quality
• private prescription and medicine costs
• shared care may be declined
• an NHS service may conduct its own review before taking over care

The private provider checklist explains professional registration, CQC limits, privacy and red flags. The 2026 cost guide shows current published fee examples and a full-pathway calculation.

Quality is not guaranteed by the funding label

An NHS-funded assessment is not automatically identical across services, and a private assessment is not automatically better or worse.

Check:

• who makes the diagnosis
• their professional registration and ADHD expertise
• how childhood evidence is handled
• whether other conditions are considered
• what the report contains
• how uncertainty is handled
• how factual corrections and complaints work

In England, CQC registration is activity-specific. CQC guidance updated in March 2026 says diagnosis-only ADHD services do not necessarily require registration for diagnostic and screening procedures. Treatment activities may be regulated. Do not use a CQC badge as the only quality test.

Treatment and prescribing comparison

Medication is a separate clinical decision

NICE says ADHD medicine should be initiated by a professional with relevant expertise after a baseline mental and physical-health assessment.

Ask each service:

1. Do you offer medication assessment?
2. Is there another wait?
3. Who manages titration?
4. Who prescribes before shared care?
5. Which monitoring is required?
6. Who provides ongoing specialist review?

Shared care

Shared care allocates responsibilities between specialist and GP. The GP may be able to prescribe after treatment is stable, but can decline the arrangement.

This is true for private care and can also matter in patient-choice pathways. Check the fallback before choosing a provider.

Read the ADHD shared-care agreement guide.

Prescription charges

NHS prescriptions are free in Scotland, Wales and Northern Ireland. In England, the current charge is £9.90 per item unless an exemption applies, and a prepayment certificate may reduce cost.

Private prescription administration and pharmacy medicine prices are separate and can be much higher.

A practical decision method

Score each available route from 0 to 2:

Do not total the score blindly. Treat a zero for clinical quality, safety or affordability as a reason to pause.

Do not use an assessment route as crisis care

If depression, anxiety, substance use, sleep problems or safety concerns need help, contact the relevant NHS service now. An ADHD wait or private booking does not replace urgent mental or physical-health care.

Support while deciding or waiting

You can use low-risk organisational strategies and ask for adjustments based on functional barriers. A formal diagnosis is not required for every form of support.

The guides to executive function strategies, reasonable adjustments at work and support while waiting offer practical next steps.

Where mentoring fits

Mentoring cannot select a clinical route for you, verify assessment quality or secure shared care. It can help organise questions, records and practical routines while you decide or wait.

If that independent non-clinical support fits your needs, you can book a free 15-minute discovery call. Clinical route, diagnosis and medication questions belong with the GP or provider.

Key points

• Funding route does not determine assessment quality.
• Compare assessment, treatment and follow-up separately.
• Right to Choose is an England-only NHS patient-choice route.
• Private care needs a full cost and quality review.
• Shared care is not automatic under any external pathway.
• Current waits and prices must be checked directly.
• Mentoring supports practical functioning, not clinical decisions.
