Hello mech , what a nightmare for you . You should be able to get a proper form from the environmental section off the council . You keep 2 weeks or so of writing in and recording times dates and type of noise , and then send that back for them to assess . If they consider it to be of nuisance to your health and comfort they will then visit the neighbour with a warning , or will set up a tape recording to catch the level of noise , and may wish to be called at the time of disturbance if the warning hasn't worked.
