Understanding assessment costs

Why costs vary so much

Private ADHD and autism assessments are not priced the same way everywhere. Costs vary widely between providers, depending on things like the clinician's profession, the length and depth of the assessment, whether it's for a child or an adult, and whether the service is delivered online or in person.

Because there is no single national price list, it's important to treat any figure you see online as a rough starting point only, not a promise. The only reliable way to know what something will cost you is to ask the provider directly for a current, written fee schedule before you book anything.

What tends to influence price

Several factors commonly affect what a provider charges, including:

• The professional background of the assessor (for example, psychiatrist, clinical psychologist or specialist nurse)
• Whether the assessment is for ADHD, autism, or both together
• The number of appointments involved and how long each one lasts
• Whether questionnaires need to be completed by teachers, partners or family members
• Whether a written report is included, and how detailed it is
• Whether follow-up appointments or ongoing prescribing are part of the package

Questions worth asking before you book

It's reasonable, and expected, to ask a provider clear questions before committing. Consider asking:

• What exactly does the fee cover, from first contact to final report?
• Are there any extra costs I should expect later, such as follow-up letters or shared care arrangements?
• Is payment required upfront, in instalments, or after the assessment?
• What happens if I need to cancel or rearrange an appointment?
• Is there a cooling-off period or refund policy?

A reputable clinic should be able to answer these clearly and give you something in writing. If a provider is vague about costs or reluctant to put fees in writing, that's worth noting when you're comparing options.

Comparing providers fairly

When comparing services, try to compare like with like. A lower headline price might not include a full written report, or might require you to pay separately for follow-up appointments. A higher price might include more clinician time, additional questionnaires, or post-diagnosis support. Reading the small print, or simply asking, will give you a much clearer picture than the headline number alone.

It can also help to ask whether the fee is fixed or whether it could increase depending on what's found during the assessment - for example, if additional appointments are recommended part-way through.

NHS and Right to Choose routes

Cost is one of several reasons people consider private assessment, but it's worth remembering that NHS pathways and Right to Choose options may also be available to you, sometimes without the fees associated with private care. Waiting times and availability for these routes vary by area, so it's worth exploring them alongside private options and asking your GP what's available locally.

A note on affordability

If cost is a barrier, it's worth asking providers directly whether they offer any flexible payment arrangements, or whether a shorter initial consultation is available to help you understand your options before committing to a full assessment. Some employers also offer support - this is covered in more detail in our guide to paying for an assessment.

Getting personalised advice

This guide is general information only and cannot tell you what any specific provider charges or whether a particular service represents good value for your circumstances. For advice tailored to you, speak to your GP, or contact providers directly and ask for their current fee information in writing.

Understanding the shape of a fee - what's included, what isn't, and when payments fall due - puts you in a much stronger position to make a decision that's right for you, without any pressure or surprises along the way.
