The Electricity (Hazards from Trees) Regulations 2003

To protect the safety of the public and electricity supply security, the Government has enacted the Electricity (Hazards from Trees) Regulations 2003 (hereafter referred to as The Regulations), the purpose of which is to:

  • prescribe minimum distances from power line conductors that trees and other vegetation must not encroach
  • set rules about who has responsibility for cutting or trimming trees or other vegetation, to maintain these minimum distances
  • assign liability if these rules are breached and
  • provide an arbitration system to resolve disputes between line network companies (like Top Energy Ltd) and tree owners, about the operation of these regulations.

The Regulations apply to trees and vegetation on public and private land.

The Electricity (Hazards from Trees) Regulations 2003 specify precisely the distances trees and other vegetation must be kept from power lines. If vegetation grows within these minimum distances (or Zones) cutting or trimming will be necessary. These zones are known as the Growth Limit Zone and the Notice Zone (or Hazard Notice Zone). The Growth Limit Zone is the MINIMUM clear space around power lines that must be maintained, even in stormy conditions. The Notice Zone extends a further one metre beyond the Growth Limit Zone and serves as a hazard warning zone. See diagram below.
