No, it is not; it is a policy that is unlawful in the light of the BG v Suffolk case from 2021. Financial assistance for holidays, in the context of either respite or accessing the community, and for any aspect of that holiday if there is nobody willing to pay for it, cannot be excluded from the scope of the Care Act after this judgement.
If it was said in an individual’s Care Act process, about why that individual was not going to be funded for a holiday, that might be a justifiable position to take, depending on the rationale.
