Interesting to hear other stories too. The landlady did talk to me in the summer and introduced herself and said if they were to noisy to let her know. But as the money is coming in (well most from the taxpayer) I doubt she would care now but I guess a word might not hurt , but at best she wouldn't renew the lease I'm guessing.
Its not as simple as that, getting tenants out who dont want to leave cant be a very difficult, drawn out and expensive process.. This is a good thing in many circumstances (protects tenants against dodgy landlords) but has its flipside.
As a landlord if we had a problem tenant that knows the law and decided to play you it would take approx 9 months to get them out. Thats 9 months in which they will usually stop paying rent, will potentially damage the property and the landlord is still liable to repair and maintain it!! Fortunately most tenants are NOT like that, but some are..
Definately have a gentle chat with the LL if you can, but understand that there is usually not a lot they can do.
