help please regarding accessibility

Hi again
Having relented on our choice of preschools and agreed for our 3 yr old in a power wheelchair to go to a more accessible enviroment in an alternative preschool (in order to pick our battles and this wasnt one of them!).

We have recieved a call from the SEN team at the local authority questioning our choice of primary school!! Jacobs older brother and sister attend it (therefore obvious choice) he already knows a number of children and teachers, its in our catchment etc. etc.

They want to organise a prelimary meeting at the school with physio, OT and building control to see if it is ‘feasible’ or indeed ‘appropriatte’ for him to attend and whether another local school in the area which is already accessible would be ‘more appropriatte!’ I thought we could choose and the law was on our side – or am I just very naive.
If nothing else it would be impossible for him to attend anywhere else due to the logistics of being in two places at once –
He already misses half an hour of preschool every morning due to me dropping off his siblings and then crossing town to get him into an ‘accessible preschool’. This surely cant happen when he starts school.
Has anyone else had this issue?
Sorry rant over
