SEN Advocacy & EHCP Support in West Sussex
Local SEND context
EHCP and SEN advocacy insight for West Sussex
For families in South East, the practical question is not just how West Sussex 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.
West Sussex is responsible for 10,945 active EHC plans, with 1,816 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.
Looking at the trend rather than a single year, EHC plans in West Sussex have risen 107% since 2018 — from 5,297 to 10,945 in 2025. A rising caseload can mean longer waits and more pressure on decision-making, so preparing a strong request matters more, not less.
Only 14% of new EHCPs in West Sussex were issued within the statutory 20-week timescale (257 of 1,816). Families facing this level of delay should focus on submitting a robust request from the start and keeping a clear paper trail if deadlines slip.
West Sussex'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.
