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.
Do you actually need to pay for an ADHD assessment?
A short honest router that points you to the cheapest legitimate route for your situation, NHS, Right to Choose or private.
NHS vs Right to Choose vs private: cost and wait
All three routes side by side, with typical cost and typical wait together, not one or the other.
Right to Choose eligibility checker (England)
A plain-language checklist that tells you whether you are likely eligible for NHS Right to Choose, and the next step.
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.

What the first year really costs on the private route once assessment, titration and prescriptions are added up, against the free NHS route.
Private ADHD assessment cost estimator
Estimate the cost-to-stable of a private assessment by provider type and region band, not just the headline fee.
ADHD medication monthly cost estimator

Editor, ADHD Helper
Adam leads ADHD Helper's editorial coverage of adult ADHD, and he writes it from lived experience: Adam has ADHD himself, diagnosed as an adult, and has been through the assessment routes and the daily workarounds this site covers. He is the founder and managing director of Muswell Rose and researches 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.
