EHCP for ADHD in the UK: Waiting Lists, Right to Choose, and Your Child's Rights

Over 316,000 people in England were waiting for an ADHD assessment as of mid-2025. NHS wait times average 17 months — and in some areas, families are waiting three to four years. Simultaneously, children are struggling in classrooms without support, while schools and local authorities insist a formal diagnosis is required before anything can be done.

Both of those things — the waiting and the insistence on a diagnosis first — are the wrong frame for how SEND law actually works in England.

What the SEND Code of Practice Actually Says

The Children and Families Act 2014 and the SEND Code of Practice that accompanies it operate on a needs-based model, not a diagnosis-based one. A formal medical diagnosis of ADHD is not legally required for:

• A school to provide SEN support
• A parent to request an EHC needs assessment
• A Local Authority to initiate an EHCP assessment

Schools have a legal duty to identify and support children with special educational needs at the earliest opportunity. This duty applies from the moment a child's difficulties are observable and impacting their ability to learn — not from the date of a medical letter.

If a school tells you "we need the ADHD diagnosis before we can put anything in place," they are not following the SEND Code of Practice. Document the statement and cite paragraph 6.14: schools must not wait for a statutory plan before providing support.

Education, Health and Care Plans: What They Are and How to Request One

An EHCP (Education, Health and Care Plan) is a legally binding document, issued by the Local Authority, that describes a child's special educational, health, and social care needs and the specific provision that must be made to meet those needs.

To begin the process, either the school or the parents can request an EHC needs assessment directly from the Local Authority — specifically from the Director of Children's Services. Make the request in writing (dated email with read receipt). The LA is legally bound to respond within 6 weeks to confirm whether they will proceed.

If the LA refuses to carry out an assessment, parents have the right to appeal to the SEND Tribunal. The Tribunal upholds parents' appeals at very high rates — the most recent figures show parents winning more than 90% of tribunal cases that proceed to a decision.

Even where the school initiates the referral, parents can and should write their own letter to the LA simultaneously. Parental requests carry the same legal weight as school-initiated requests.

The ADHD Assessment Waiting List Crisis

The NHS diagnostic backlog for ADHD is severe. What options do families have while waiting?

Option 1: Wait on the standard pathway. This is the default — and in many ICBs (Integrated Care Boards), it means 18 months to 3+ years for a community child and adolescent mental health services (CAMHS) appointment. During this time, schools should still be providing SEN support based on observed need.

Option 2: Use the NHS Right to Choose (RTC). Under the NHS Choices Framework, patients in England have the legal right to ask their GP for a referral to any CQC-registered provider that offers the service they need and holds an NHS contract. For ADHD, this includes providers like Psychiatry UK, ADHD 360, and Clinical Partners. Wait times via Right to Choose vary by provider and ICB, typically ranging from 18 to 49 weeks — significantly faster than standard NHS pathways in most regions.

To use RTC, the process is: GP referral → choose an approved independent provider → provider accepts referral → assessment is funded by the NHS at no cost to the family. GPs can decline an RTC referral if there is a "clinical reason" — but being unfamiliar with RTC, or a preference for the standard pathway, is not a clinical reason.

Option 3: Private assessment. A private ADHD assessment in England typically costs £500–£1,500 depending on provider and complexity. Private assessments produce a diagnostic report that can be shared with schools and used as supporting evidence for an EHCP application. Schools and local authorities cannot legally dismiss a private diagnosis — though some attempt to minimize its weight. An EHCP must be based on need, not source of diagnosis.

What Schools Must Provide Before an EHCP Is in Place

Many parents believe their child is unprotected while waiting for an EHCP assessment to conclude. This is incorrect. The Equality Act 2010 applies to all students with a disability or impairment — and ADHD qualifies. Schools must make reasonable adjustments for disabled pupils whether or not any formal SEND plan is in place.

Reasonable adjustments for ADHD include: providing written instructions alongside verbal ones, preferential seating away from distractions, access to movement breaks, and reduced task volume. These do not require an EHCP or even a formal SEN Support plan — they are triggered by the Equality Act obligation alone.

At SEN Support level (below EHCP), schools must also follow the Assess, Plan, Do, Review cycle, documenting the student's needs, the interventions in place, and the progress being made. Parents should receive at least two formal reviews per year.

EHCP Contents for ADHD

When an EHCP is finally issued for a student with ADHD, the quality of the document matters enormously. A vague EHCP — one that describes needs in general terms and specifies provision as "small group support as appropriate" — is not enforceable. A good EHCP:

• Names specific executive function deficits (working memory, task initiation, time management) using assessment data
• Lists each provision with specificity: frequency, who delivers it, where, and for how long
• Specifies measurable outcomes for each area of need
• Names the school where provision will be made

Section B (needs) must be directly linked to Section F (provision). If the need is described but no provision is specified for it, the LA has failed to meet its legal duty. Parents can appeal to the SEND Tribunal on both Section B and Section F.

If the Local Authority Refuses the EHCP Assessment

A refusal letter from the LA must explain the reasons for refusal. Common grounds include: "the school can meet needs from within its own resources" or "needs are not sufficiently complex." Both of these can be challenged at tribunal if:

• The school has documented the student's needs and is struggling to meet them despite existing provision
• Private assessment or professional reports indicate needs that the LA's threshold ignores

IPSEA (Independent Provider of Special Education Advice) provides free legal advice and template appeal letters. The SEND Tribunal is free to use.
