6 months contract and renting a flat

[SueEllen]

As a landlord, a tenant renting for the 6 months planning on bailing in the short, I'd be livid. Use a nice BnB.

A lodger isn't a tenant.

A lodger shares the property with the owner and uses the same facilities. They can have a room but the room may not be for their own exclusive use. They have very few legal rights and can have no notice period so can easily be kicked out.

Its a legal requirement that all tennancy agreements are for 6 months...

No it isn't. Most are, and there are good reasons for it being like that, but you can have tenancies of any length or for a rolling period.

That rather depends what the contract says of course. However IIRC you are not advised, as the landlord, to give your lodger a key to lock their room because then they get back a lot of those rights and cannot be booted out - I think?
