Is it just you, or are other neighbours affected?
Protection from Harassment Act 1977
This law aims to maintain social standards, defined by your 'course of conduct'. Basically, it is an offence for someone to conduct themselves in a way that amounts to harassment of another. This covers any course of conduct that takes place in a public or a private place. It means your neighbour can't just let his bulldog take a dump on your doorstep, switch on the Home Karaoke at three in the morning simply to annoy you, or abandon fridges in your yard. Offenders could face up to six months in jail if found guilty. Just be aware that you have to prove your neighbour's motivation for behaving badly was to wind you up.
Crime and Disorder Act 1998
A recent range of measures designed to tackle neighbourhood bad behaviour such as drunkenness, violence, intimidation and even swearing. Most notably, you can appeal to the police and your local council authority and have them ask the magistrates court to impose an Anti Social Behaviour Order (ASBO) on main offenders - including those under 18. This civil action can involve restricting a persistent troublemaker from entering a geographical area or banning them from certain acts - like turning the air blue outside your house at midnight every Friday while dressed in nothing but a traffic cone. Should a court hearing go ahead, the magistrate will want to hear evidence backing the case - usually from several people in the community - and will also consider the defendant's circumstances to be sure they're not being discriminated against.
