Contrary to popular belief there are no set time periods when noise can be classed as causing a nuisance. If the noise in question is unreasonable and excessive, it has the potential to cause a Statutory Nuisance at any time of the day or night. Although anti social hours do tend to be more of a problem.
Neighbours need to show a certain amount of tolerance towards each other, as we all make noise at some point. However, neighbours also need to be considerate and mindful of the noise they make and take reasonable steps to make sure they do not cause a nuisance to their neighbours.
If you are going to be carrying out DIY or you are having a party, try and mention it to your neighbours in advance and remember to try and make sure that noise is kept to a minimum, particularly at anti social times.
There are many factors involved in assessing whether a noise constitutes a Statutory Nuisance, such as frequency and duration of events, the level of the noise and whether it materially affects the enjoyment of neighbouring properties.
