Local authority obligations to provide supported housing

if he is no longer living with us

Have you had a sit down discussion about what life will look like when he leaves home?

If he is like 99% of other teenage boys, he will only see the freedom and independance and not the costs / cooking / cleaning / washing / maintenance / loneliness elements that come on such a journey.

If he is set on the move no matter what, then maybe try to write out for him a list of all the things that you need to do to live on your own and the things he needs to learn to do them.

Stuff like:

You will get £xx per week from benefits / job and this needs to go to cover the following (food, transport, entertainment, tech (phone, laptop replacements, contracts), clothes, medical (dentist, plasters, glasses etc) insurance, utility bills, socialising, savings etc).

Explain the importance of having some savings for when you need something in an emergency (laptop/phone gets tea spilled on it for example)

I recall my brother being given this talk and he quickly changed his mind about moving out when he realised he would probably be in debt from day 1 and only get worse from there. He also became much more aware of how much the family were providing for him and made him appreciate it more.

Probably also arrange to show him how to use things like the washing machine and dish washer, explain how often to change bedclothes & towels, how not to much whites and colours when washing clothes, what to use to clean the different parts of the house with etc.

Ideally on day 1 I would leave a box of things he would no think about - cleaning supplies, bedsheets/towels, salt / pepper / tea / cutlery etc and help get the utility bills in his name if he is going to be responsible for a flat.

Maybe also show how to clean effectively as it is all too easy to damage surfaces with the wrong product, or damage skin with bleach etc. Remember to explain the importance of ventilation.

These are some of the things I wished I had when I started out, but my parents were overseas working so I had to find my way on my own.

I'll be honest probably not, supported housing usually isn't given to "high functioning" autistic people because it is wrongly presumed we don't need regular help.
The most I got when I moved into a flat was someone came around and helped me work out a budget, that was it, then I got left to it and my anxiety and depression of feeling overwhelmed by the responsibility turned me towards alcohol abuse and a sui***e attempt.
Here is (in my opinion, with hindsight) based on my own experiences how it should have happened to avoid the absolute mess that robbed me of 5 years of my life: First of all I shouldn't have been kicked out to then have 0 contact with anyone for advice and someone should have popped their head in every other week until I got established so I could talk about my anxieties rather than have them fester into a shame cycle spiraling down the hole to self oblivion.
You need to stay in contact, not just on the phone but physically visit, have means in place that if he's having a no functioning day someone can come round with a tin of sandwiches and put a load of laundry in the machine for him. Don't shame or scold the negative (that just adds to the anxiety and depression) but encourage and kudos any positive steps he takes towards his own self care and regulation, you really have to reinforce the healthy connections in the brain to get good habits to stick. Watch out or any dangerous signs of downward spiral that he may be hiding from you, the time to intervene to stop a fall is as near to teh top as possible, don't wait for him to get to rock bottom. He won't hit the ground running right away, it may even take many months but if you can hold him steady long enough for him to get into gear himself he will be okay when he gets into the rhythym of doing the running of the place for himself. Because the more stable he is mentally the less help he will need overall anyway.
