In the UK, Statutory Nuisance (SN) is a legal term defined in the Environmental Protection Act 1990. It refers to any activity that causes a nuisance or annoyance to the public, whether in the form of air, water, light, noise, or smells. It also covers nuisances caused by animals, insects, and plants, as well as anything else that may interfere with the comfort or convenience of the public. SN is used to protect public health and safety and can be enforced by local authorities. The purpose of SN is to ensure that the public environment is free from any activity that may cause a nuisance or annoyance. It is designed to address issues such as excessive noise, noxious odours, smoke, dust, insects, and animals. SN applies to any kind of property, including residential, commercial, and industrial. It also applies to public spaces, such as parks and sidewalks. SN can result in fines, court orders, and even prison sentences.
