How Much Does a Private Dyslexia Assessment Cost in the UK? (Adults and Students, 2026)

A private diagnostic dyslexia assessment in the UK usually costs about £300–£900 in 2026, report included. Specialist teachers with an Assessment Practising Certificate sit at the lower end and HCPC-registered psychologists cost more: the BDA charges £690 with a specialist teacher and £882 with a psychologist, including VAT. The NHS does not routinely assess adults, and Student Finance does not refund the fee.

If you already know you want a full assessment, you can book a dyslexia assessment with us, or speak to our team first if you have questions about fees or reports.

Remote assessment is not always cheaper: the BDA charges the same for remote and in-person dyslexia assessments, and offers remote only from age 12.

Why quotes differ: specialist teacher (APC) or psychologist (HCPC)?

Two kinds of professional can carry out a diagnostic dyslexia assessment in the UK, and they are priced differently.

Specialist teacher assessors hold an Assessment Practising Certificate (APC). APCs are issued by bodies approved through the SpLD Assessment Standards Committee (SASC): the BDA, the Dyslexia Guild and PATOSS. An APC is valid for three years from the date of issue, and the holder must keep their membership of the issuing body for the whole period, or the APC becomes invalid.

Psychologists carrying out dyslexia assessments, often educational psychologists, must be registered with the Health and Care Professions Council (HCPC).

Both routes can diagnose dyslexia, and both are accepted as evidence for Disabled Students’ Allowance. Gov.uk asks for a diagnostic assessment “from a practitioner psychologist or a suitably qualified specialist teacher”. You do not need to pay psychologist rates to get a report Student Finance will look at. A psychologist assessment is mainly worth the extra cost when a broader cognitive picture is needed, for example where several explanations for your difficulties are being weighed up.

Check before you pay. Ask a specialist teacher for their APC certificate and its expiry date. Ask a psychologist for their HCPC number and look it up on the HCPC register. For DSA, the BDA says the assessor must have a current APC at the time of completing the assessment and writing the report. A lapsed APC can leave you with a report you cannot use.

What your fee should include

A fair all-in price for a full diagnostic assessment normally covers:

• a pre-assessment questionnaire covering your history, education and current difficulties
• the assessment session itself, with standardised tests of reading, spelling, writing, memory and processing
• scoring and analysis by the assessor
• a full written diagnostic report following SASC guidance, with a clear diagnostic opinion and recommendations
• feedback on the findings

For how the finished report is used afterwards, see whether a dyslexia report can be used for school, university or work.

Watch for split pricing. Some assessors price the assessment and the full report separately. One independent provider currently lists an adult assessment at £549 and the full diagnostic report at a further £399, so the real cost is £948. Always ask for the price that includes the full diagnostic report.

A screening is not a diagnosis. Screeners are shorter and cheaper (one independent assessor charges £299 for an initial screening), and they can help you decide whether to go further. They are not a diagnostic assessment, so they do not meet the DSA evidence requirement, which asks for a full “diagnostic assessment”.

Does Student Finance (DSA) pay for a dyslexia assessment?

No. Disabled Students’ Allowance does not reimburse the diagnostic assessment. You need the diagnostic report first, because it is the evidence you send with your DSA application: for specific learning difficulties such as dyslexia, gov.uk says you “must provide a copy of a ‘diagnostic assessment’ from a practitioner psychologist or a suitably qualified specialist teacher”.

There is one useful exception to the “you pay” rule. Gov.uk also says “You could get extra money from your university or college to pay for a new diagnostic assessment”. That money comes from your institution, not from Student Finance.

Once your application is accepted, you’ll be asked to attend a Study Needs Assessment with an approved, independent assessor, who recommends the support you need.

DSA can then help with specialist equipment and software, non-medical helpers and other disability-related study costs. If a computer is recommended, you pay the first £200. Undergraduate and postgraduate students can get up to £27,783 a year in support (2026 figure; gov.uk updates it each academic year).

What the report needs for DSA

• It must be a full diagnostic assessment, not a screening.
• The assessor must have held a current APC, or be an HCPC-registered practitioner psychologist, at the time of the assessment (BDA; gov.uk).
• It should follow SASC report guidance.

There is no lower age limit on the report. Following a Department for Education change, dyslexia/SpLD reports undertaken at any age will now be accepted for DSA, so a suitable report from school may already be enough. Check with your university’s disability service before paying for a new one.

How to keep costs down as a student

Talk to your university disability service before you book anything. Many universities part-fund or subsidise diagnostic assessments. Two examples: the University of Liverpool’s Diagnostic Assessment Fund reimburses up to £250 towards the cost (it reopens on 12 October 2026 for 2026/27), and Roehampton asks students to contribute towards a full diagnostic assessment, usually £100. Schemes vary widely and some have deadlines or require you to use a named assessor, so read the conditions before you pay privately.

Ready to book? If you need a report for DSA and your university can’t help, you can book a dyslexia assessment with one of our APC-holding SpLD assessors.

Can an employer or Access to Work pay?

Access to Work is a government grant for people in England, Scotland and Wales who are in paid work, including employment, self-employment, apprenticeships, work trials, work experience, internships and work placements. It does not cover voluntary work. Dyslexia is named as an eligible condition, and gov.uk says: “You do not need to be diagnosed with a condition to apply.”

Access to Work funds support in the job, such as specialist equipment and assistive software or a support worker. It does not pay for a diagnostic assessment. Because no diagnosis is needed to apply, you may not need a private assessment at all just to get workplace support.

Employers are not obliged to pay for an assessment, but some will. Dyslexia Scotland suggests asking your employer to cover all or part of the cost if it will help you work to your strengths. A workplace needs assessment, which looks at adjustments for your role, is a different thing from a diagnostic assessment.

In Northern Ireland, a separate scheme, Access to Work (NI), is run by the Department for Communities.

Is a dyslexia assessment free on the NHS?

Not for adults, as a rule. South West Yorkshire Partnership NHS Foundation Trust says adult diagnostic assessments for dyslexia “are not currently available on the NHS”, which is why it now sells a paid assessment to local residents. Dyslexia Scotland also states that there are no free assessments for adults. That does not mean adults cannot be diagnosed: dyslexia can be assessed and diagnosed in adulthood through a private assessment.

For children, the first step is usually the school’s SENCo, who can arrange support and, in some cases, assessment through school.

Private medical insurance rarely covers a dyslexia assessment, because it is an educational assessment rather than a medical one.

Exam access arrangements (16–18): don’t pay for the wrong report

If you are 16–18 and want extra time or other access arrangements in GCSEs, A levels or similar exams, a private report may not be accepted. The JCQ rules for 2025/26 are clear:

• the school or college’s appointed assessor must carry out the assessment for access arrangements
• if an external assessor diagnoses dyslexia, the assessment can only be used as evidence for access arrangements if that assessor has liaised with the school or college and received its access arrangements paperwork before the assessment takes place
• a diagnosis on its own does not entitle a student to access arrangements

Speak to the SENCo or exams officer before you book. If you go ahead with a private assessment, tell the assessor it is for exam access and make sure the liaison happens first. Otherwise you may pay for a report the centre cannot use for that purpose.

What if the assessment points to something other than dyslexia?

Difficulties with attention, working memory and processing speed overlap across several conditions. At Harley Street Mental Health, the assessor considers whether other factors may be affecting learning, such as attention difficulties, anxiety, autism or language needs, and the report will say so if further assessment would help. A dyslexia assessment cannot diagnose ADHD, which needs a separate psychiatrist-led assessment. Because we also assess ADHD and autism, you can ask us about the next step without starting again elsewhere. If ADHD is a possibility, see our adult ADHD assessment.

Frequently asked questions

Is a dyslexia assessment worth paying for as an adult?

A diagnostic report is the evidence you need to apply for Disabled Students’ Allowance, and it can support requests for reasonable adjustments at work. Access to Work can fund software and support without a diagnosis, so think about what you need the report for before you book. A report can support applications, but it cannot guarantee any particular outcome.

Will Student Finance refund my dyslexia assessment?

No. Disabled Students’ Allowance needs the diagnostic report as evidence before you apply, and it does not reimburse the assessment fee. Your university or college may give you extra money towards a new diagnostic assessment, so ask its disability service before you book.

Does a dyslexia report for DSA have to be done by a psychologist?

No. Gov.uk accepts a diagnostic assessment from a practitioner psychologist or a suitably qualified specialist teacher. In practice that means a specialist teacher who held a current Assessment Practising Certificate at the time of the assessment, or an HCPC-registered psychologist, with the report written to SASC guidance.

How much does the British Dyslexia Association charge for an assessment?

The BDA charges £690 including VAT for a dyslexia assessment with a specialist teacher and £882 including VAT with a psychologist (prices checked October 2026). Remote dyslexia assessments are the same price and available from age 12; in-person assessments are available from age 8.

Can I use an old childhood dyslexia report for DSA?

Often, yes. There is no longer a lower age limit on diagnostic reports for DSA, so a full diagnostic assessment by an assessor with a current APC or HCPC registration, written to SASC guidance, may be accepted whatever your age at the time. Check with your university disability service before paying for a new assessment.

Do I need a diagnosis to get Access to Work?

No. Gov.uk says you do not need to be diagnosed with a condition to apply, and dyslexia is named as an eligible condition. Access to Work funds workplace support such as assistive software and support workers, not the diagnostic assessment itself.

Is an online dyslexia assessment cheaper or less valid?

Online assessments are often priced the same as in-person ones; the BDA, for example, charges the same and offers remote dyslexia assessments from age 12. Validity depends on the assessor’s qualifications and the report format, not on whether the assessment was carried out online or in person.
