EHCP Support in Hillingdon: Deadlines, Performance & Local Help

Hillingdon issued 90.8% of new EHCPs within the statutory 20-week deadline in 2024. That is above the national average of 46.4% — by 44.4 percentage points.

Based on 361 new EHC plans issued by Hillingdon in 2024.

In plain English: if you applied for an EHCP in Hillingdon this year, statistically around 91 in every 100 families received their plan on time. The remaining 9 in 100 waited longer than the law allows. A missed deadline does not weaken your rights — the council still has the same legal duty to issue the plan, and you have routes to challenge delay.

Anyone — a parent, the young person (16+), or someone acting on their behalf (school, GP) — can ask Hillingdon for an Education, Health and Care needs assessment. The request is a short written letter or email to the SEN team explaining why your child may need provision beyond what is normally available in school.

The council has 6 weeks to decide whether to assess. If they agree, the full process to issue a final plan must complete within 20 weeks of your original request.

If Hillingdon misses the 6-week assessment decision or the 20-week final plan deadline, you have clear options: chase in writing, escalate to the council's complaints process, complain to the Local Government and Social Care Ombudsman, or apply for judicial review in serious cases. Exemptions are narrow and listed in Regulation 13(3) of the SEND Regulations 2014.
