SEN Advocacy & EHCP Support in Hillingdon
Local SEND context
EHCP and SEN advocacy insight for Hillingdon
For families in London, the practical question is not just how Hillingdon performs on paper, but what the local data means for a child who needs support now. The figures below help identify where delays, disputes or evidence gaps may create pressure points.
Hillingdon is responsible for 3,469 active EHC plans, with 423 new plans recorded in the latest 2025 data. For parents, that means EHCP decisions are being made inside a busy local system where clear evidence and a well-structured request can make a material difference.
Hillingdon issued 75% of new EHCPs within the 20-week timescale (316 of 423). Timeliness is only one part of the picture: families should still check whether sections B, F and I are specific, quantified and enforceable.
Hillingdon's most recent Area SEND inspection outcome was inconsistent. This provides useful background, but individual EHCP decisions still turn on the child's assessed needs, the available evidence and whether provision is written clearly enough to be enforceable.
Hillingdon covers families in Belmore, Charville, Colham & Cowley, Eastcote, Harefield Village, Hayes Town, Heathrow Villages, Hillingdon East, Hillingdon West, Ickenham & South Harefield, Northwood, Northwood Hills, Pinkwell, Ruislip, Ruislip Manor, South Ruislip, Uxbridge, West Drayton, Wood End, Yeading and Yiewsley and other areas within London.
