ADHD tools and checkers

These free ADHD tools help UK adults make an informed choice before paying for anything. They work out whether you need to pay for an assessment at all, compare the NHS, Right to Choose and private routes by realistic cost and wait, check Right to Choose eligibility in England, screen symptoms with the validated ASRS instrument, and estimate assessment and medication costs. Every tool is information only and never a diagnosis.

Information only, not medical advice and not a diagnosis. Only a registered clinician can diagnose ADHD or make treatment decisions. If cost is a barrier, the NHS route, including Right to Choose, is free at the point of use. If any tool raises a concern, speak to your GP.

Before you pay: route and eligibility

The honest tools that private clinics tend to bury. They surface the free NHS Right to Choose route before any private cost.

Screening

A validated public screening instrument. A screener is a prompt to seek assessment, never a diagnosis.

Data and waiting times

Curated, fully sourced figures so the numbers behind the routes are out in the open. Published figures only, never our own estimates.

Cost estimators

Realistic cost ranges built from published prices and NHS charges, so the total is clear before you commit.

He researches and writes the plain-English explainers on getting an ADHD assessment through NHS Right to Choose or privately, and on the products and tools people use to manage ADHD, drawing on guidance from the NHS, NICE and the Royal College of Psychiatrists. He is clear that the site is information, not medical advice, and that diagnosis is for a registered clinician.
