To not want a home visit - can I get out of it easily?

[ReanimatedSGB]

DS was recently diagnosed with autism (HFA), it's fine, we thought it was the case etc, and stuff like extra time in exams and the potential of a queue-jumper card for theme parks is all good.
But I have had an email saying we have been referred for a home visit. I do not want home visit. The house is a mess and I have huge amounts of work to do. Can I say no or at least ask why they want to come? No mention of it was made previously...

Who is proposing to visit and what is the purpose of the visit?
If you don't know, ask. It is absolutely your right to ask! Rude of them not to explain.
You could I would think easily say you'd prefer to meet at their workplace
I imagine though it is about meeting DS somewhere he feels comfortable. Nothing sinister.

When have they said they're coming?

You’re on a hiding to nothing if you think every bit of ‘support’ offered is worth grabbing on to - the overwhelming majority is not ... not evidenced based, badly delivered & administered, improperly (or not at all) personalised for the child and family. I say this as a veteran parent of an autistic child - at best the overwhelming majority is pointless & worst it is damaging. Identify what you need & want & don’t waste tine jumping through NHS & CAMHS hoops. It is a tick box exercise to them.

Just looked at the email again - someone who is a Family Support Co-ordinator for the National Autistic Society. I'll arrange to meet them in Costa or something instead. I still don't know what they actually want or are offering, but I'll try phoning in the morning.
