End of student tenancies as we know them?

Hello, Reading about the Renters’ Right Bill, it appears to me that if you have let a property to a group of students on a new periodic tenancy then one student can terminate the whole tenancy on two months notice.

Does it mean that that student can walk away and leave the other students without a valid tenancy agreement?

As I understand it, once a one joint tenant serves notice the whole tenancy will cease to exist.

Whilst in normal circumstances the landlord would probably grant a new tenancy to the remaining students and hope to fill the empty room, is it possible that the landlord could tell the remaining students they must leave when the notice expires which would leave them very exposed?

This would obviously only happen if the landlord had an alternative use for the house.

Reading the press it appears that there may be opportunities to lease to the government for migrants and that may prove to be more attractive.

I am just curious to know what position the remaining students would be in if the landlord decided that they wanted to take the house back?

Thank you,

Joanna
