One is not eligible for a service, one is eligible for HELP, and the response to the eligible need is for the care planner to decide about, using their professional competence, and subject to judicial review challenges on the usual grounds.
The LGO prefers to not to stray onto the sphere of the assessor’s expertise, and continues to consider whether the process in deciding eligibility was reasonable, rather than the findings themselves. Councils are not at fault for failing to find people eligible, if the Council followed the proper process.
However, if assessments indicate no change in needs, but the Council removes aspects of support, the LGO is more likely to come to a conclusion that Council acted contrary to guidelines, and find fault. It is possible for that to happen lawfully, but not easily. A change in the price for care, or a change in the means for delivering care, would be other reasons a plan could be cut.
