Tenancy agreements

[Golfman]

Hi all, I am converting my house into 3 bedsits/studio flats, and will be letting out the first one in around 1 month.

Does anyone know where to obtain tenancy contract/agreements? This is the first time I have done this and want to make sure I am doing everything correctly.

I have done a Google but there are so many different variations I want to make sure I use the correct one!

Thanks
