Does a Diagnosis Matter for an EHCP? What Weight Does It Actually Carry?

One of the most common questions we hear from parents is:

“Does my child need a formal diagnosis to get an EHCP?”
Or:
“Will going private help us get the right support faster?”

It’s easy to feel like without a label, your child won’t be taken seriously. And sadly, in many cases, that’s what parents are told—by schools, by professionals, even by local authorities.

But here’s the truth:

An EHCP is about needs, not labels.

Legally, your child does not need a diagnosis to be assessed for or receive an Education, Health and Care Plan.
The EHCP should be built around:

• What your child is struggling with,
• What is (and isn’t) working in their education,
• And what provision is necessary for them to make progress.

A diagnosis can help clarify those needs—but it is not a legal requirement.
What matters most is evidence: observations, school reports, assessments, and your own input as a parent.

So… Is a Private Diagnosis Worth It?

This depends on your situation.
Going private can:

• Speed up a process that’s taking years on the NHS,
• Give you clearer language to advocate for support,
• Or unlock understanding and peace of mind for your family.

But it won’t guarantee an EHCP, and it can be expensive—often £800 to £2,000+ per assessment.

If you go private, choose professionals who understand the EHCP process and will write clear, needs-focused reports with specific recommendations. That way, they can actually help inform the plan—not just give a label.

What Should an EHCP Focus On?

Too many EHCPs get stuck listing diagnoses without really tackling what your child needs in daily life.

What matters most is:

• What does your child struggle with right now?
• What’s working well? What’s falling apart?
• What specific support would help them thrive?

Those are the questions that shape a strong EHCP. Not just what your child “has”, but what they need.
