[Closed] Smoke from neighbours chimney

I live in a semi, the neighbour had a wood burner installed and it is leaking smoke into our house. I informed her politely on Thursday that it is really bad. She acknowledged the issue and said she has some one coming to look at it next week. She then agreed not to use it until it is sorted.

I have just returned from a night shift to a house full of smoke. I went round and she isn't even home. I can see the log burner through the window blazing away.

What can I do. The stuff in my loft is ruined and I can't breath let alone sleep.

My google foo is weak and I cannot find the relevant regulations.

cheers folks
