The legislation that covers high hedges are covered in Part 8 of the Anti-social Behaviour Act 2003, which gives local authorities the power to deal with complaints about high hedges that has come into operation in England since 1 June 2005.
From 1 June 2005, a resident must prove that they have tried and exhausted all other avenues for resolving their hedge dispute (such as provide evidence of all written correspondence). Then the resident can take their complaint about a neighbour's evergreen hedge to the Borough Council.
The role of the local authority is not to mediate or negotiate between the complainant and the hedge owner but to decide on whether the hedge is adversely affecting the complainant's reasonable amenity and enjoyment of their property.
If they consider the circumstances justify it, the local authority will issue a formal notice to the hedge owner which will set out what they must do to the hedge to remedy the problem, and when by.
If they don't agree with the Council's decision both the complainant and the hedge owner have the right to appeal against the Council's decision and to be heard by an independent Inspector.
Failure to carry out the works required by the final decision is an offence which, on prosecution, could lead to a fine of up to £1,000.
The Council has set the fee for a complaint at £500 with a reduced fee of £250 for households receiving Council Tax Benefit.
