How tall your garden hedge can get before facing £1,000 fine

Homeowners across the UK are being warned that their overgrown hedges could lead to formal complaints and even a £1,000 fine. The issue, which falls under government law, is designed to deal with shrubbery that is just too high – over 2m – and could affect your neighbour’s enjoyment of their property.

According to official government guidance, Part 8 of the Anti-social Behaviour Act 2003 allows councils to investigate complaints about hedges that are causing problems. The law applies where a hedge is made up of two or more evergreen or semi-evergreen trees or shrubs, and is more than 2m tall. So yes, you may need to get your trimmers out sooner rather than later.

The government explains that councils must first decide whether the hedge is affecting a neighbour’s “reasonable enjoyment” of their home or garden.

If it is, they can issue a remedial notice requiring the hedge owner to reduce its height promptly and prevent the issue from continuing.

However, councils can reject complaints if neighbours have not first tried to resolve the issue directly, according to GOV.UK. This means mediation and informal discussion are expected before any formal action is taken.

Sevenoaks District Council says applicants must provide evidence that they have tried to resolve the dispute before submitting a formal complaint. It also warns that the fee applies even if the complaint is not successful or no action is taken.

According to GOV.UK, councils assess whether a hedge is blocking light or access and whether it is harming the “reasonable enjoyment” of a property. If upheld, they can issue a legally binding remedial notice requiring action within a set timeframe.

Failure to comply with a remedial notice is a criminal offence, the government confirms. Government guidance states that offenders can be fined up to £1,000, and councils can also enter the land to carry out the required work themselves.

The legislation also makes clear that councils cannot force hedge removal or reduce a hedge below two metres in all cases. Decisions are based on balancing both neighbours’ interests and the impact on the surrounding area.

Experts say disputes over hedge height are among the most common neighbourhood complaints in the UK. While most are resolved informally, official intervention can become costly if cases escalate to council enforcement.
