Urgent legal advice on section 8 and 21 eviction notice

[Punsandroses]

Posting here for traffic, so any advice very gratefully received.
Leaving aside that adult DS has got himself into a mess, again!!! and my feelings on all of that, that's a whole other conversation.
My DS is a single adult male that has been served a section 8 and 21 on 10.20.25. with 2 weeks notice.
He emailed them back saying he would leave BUT has not signed and legal documents.
Today is the day he should leave, I've been aware of situation since last night.
I can't get through to Shelter but on their site the advice is that he will have at least 2 months notice and then at that point they would need to apply to court.
Is all that correct? also any advice on an email on wording that he could send to the landlord on that he is currently looking for an alternative place to live but won't be leaving today.
A little bit in a panic mode at the moment.

A section 8 can be served with as little as 2 weeks notice. A Sec 21 requires 2 months.

The landlord can start court proceedings from today if he doesn’t leave based on the Sec 8, which allows faster eviction than a 21.

CAB website is good.

He doesn’t have to leave today but unless he has paid the over due rent, the landlord can apply to court for a section 8 hearing. If the rent is brought up to date. They need to wait until the section 21 notice is up and then apply to court (assuming they have all the correct documents, deposit correctly secured, gas checks up to date etc).

Thank you both so much, he has paid some arrears but not all and with the section 8 presume that their intention is still to evict. As they already served the section 8 on the 10th Oct how long would he have before he is forcefully evicted?

That depends on how long the court waiting lists are.
I haven’t looked into it for a while but it used to be that the arrears had to be more then 8 weeks. So if he’s brought it below that, it would revert to a section 21.
