Adult Dyslexia Assessment: NHS vs Private Options

If you suspect you're dyslexic and go to your GP expecting a referral, you're likely to be disappointed. Dyslexia occupies a different space in the UK healthcare system compared to ADHD and autism, and the assessment pathway reflects that. Here's what you need to know about your options.

Why the NHS Doesn't Routinely Assess for Dyslexia

The NHS states that if you think you or your child may have dyslexia, the first step is to talk to a teacher or your workplace's special educational needs coordinator, or to contact a dyslexia association for advice. Unlike ADHD and autism, dyslexia is not classified as a mental health or neurodevelopmental condition within the NHS service framework, which means there is no standard GP referral pathway for diagnostic assessment.

This doesn't mean dyslexia is taken less seriously. It means the assessment route is different: it sits within the education and workplace support system rather than the health system. For adults, this creates a gap, because the education-based support structures were designed around children and students, not working professionals.

Your Assessment Options

There are three main routes to a formal dyslexia assessment as an adult in the UK.

1. The British Dyslexia Association (BDA)

The BDA offers diagnostic assessments for adults across the UK, available both in person and remotely via video. Assessments can be carried out by either a specialist dyslexia teacher or an educational psychologist.

Costs with the BDA are: £575 + VAT (£690) for assessment with a specialist teacher, or £735 + VAT (£882) for assessment with a psychologist. The process involves completing a booking pack with questionnaires, after which you'll be matched with an assessor. The BDA occasionally offers bursaries to help with assessment costs, subject to available funding.

2. Independent Assessors

Independent educational psychologists and specialist teachers with an Assessment Practising Certificate (APC) can carry out diagnostic assessments. Prices vary from around £350 to £800 depending on the assessor's qualifications and location. The BDA's guidance on types of assessment explains the difference between a specialist teacher assessment and a psychologist assessment, and when each might be more appropriate.

When choosing an independent assessor, check that they hold a current APC issued by a recognised body (such as the BDA, SASC, or Patoss). A report from an unqualified assessor may not be accepted by employers, universities, or Access to Work.

3. Some NHS Trusts

A small number of NHS trusts offer paid-for dyslexia assessments, often at lower cost than fully private options (around £400 + VAT in some cases). These are not free NHS services; they're commercial services operated by NHS trusts. Availability is limited to certain regions.

Specialist Teacher vs Psychologist: Which Do You Need?

For most adults, a specialist teacher assessment is sufficient. It's cheaper and produces a report that's accepted by employers, Access to Work, and most professional bodies. A psychologist assessment is recommended if you need the report for legal proceedings, certain professional qualifications, or if you have complex co-occurring conditions that need to be differentiated (for example, if there's a question about whether difficulties are caused by dyslexia, ADHD, or both).

How to Fund Your Assessment

1. 1

   Check whether your employer will pay. Many employers fund dyslexia assessments through occupational health, especially if you've raised difficulties at work. Ask HR or your line manager about the process.

2. 2

   Ask about union support. Some trade unions offer financial assistance for disability-related assessments. Check with your union representative.

3. 3

   Explore BDA bursaries. The BDA occasionally has funding available to subsidise assessment costs. Apply through their website.

4. 4

   Consider it a business expense. If you're self-employed and dyslexia affects your work, the assessment cost may be tax-deductible. Speak to your accountant about whether it qualifies.

5. 5

   Factor in the return. A formal diagnosis unlocks Access to Work funding (potentially thousands of pounds per year in assistive technology and support) and reasonable adjustments under the Equality Act 2010. The assessment cost is a one-off; the benefits are ongoing.

What Happens After Assessment

A diagnostic assessment produces a detailed report covering your cognitive profile, your specific strengths and weaknesses, and practical recommendations for support. This report is your key document for requesting workplace adjustments and applying for Access to Work funding.
