I've been having a discussion with someone about EHCPs on the thread, most likely the real reason is there's no funding left for this year. Our Sendco used to be on the panel for the LA and from what I understand, unless there's a specific diagnosis with a full report (i.e. it would obviously be illegal discrimination) it'll be a blanket no until next academic year. That is assuming your LA has any budget for SEND at all of course and that whoever is in government next Friday doesn't annihilate it all together.
Sorry, I wish I had something more positive say! Our SD is 14/3, so hopefully our turns will come very soon.
