Our neighbours have laminate flooring. They are a couple with 2 small children. The children run and scream and shout. Their room is above our bedroom so it wakes us up from 6am sometimes. In the evening they run around in their lounge which disturbs us.
It may be a sound insulation problem (although you will have to accept that some noise is inevitable with children). It may not be considered a “statutory nuisance” if the behaviour is normal behaviour for kids. Try talking to your neighbours and/or landlords. There are a number of improvements that can be made to help soften the impact. Be prepared to meet them half-way and accomodate any proposed improvements.
