Quick landlord questions

[camgear]

Hi,

I'm currently renting a room in a shared house, is there a statutory notice period I have to give my landlord before I leave? I've had a look at a copy of the contract and can't see anything... Also, is it usual practice to show people the room while you still live there? I don't really fancy people coming round and casing my stuff!

Thanks

I had a contract for 6 months I think, and then I think technically it needs to be renewed every 6 months? Although we never have and I've been here for 3 years...
