Commercial construction activities include building: 

  • shops 
  • supermarkets 
  • offices 
  • warehouses 
  • factories.

The general environmental duty applies to all construction sites. This means if you manage or control construction and demolition activities you must understand and proactively manage the risks of harm from noise to people and the environment.

Under the Environment Protection Act 2017, you must not emit unreasonable noise from construction sites at any time of day.

Construction noise can be unreasonable if it goes on for too long or is excessive under the circumstances.

Construction – guide to preventing harm to people and the environment (publication 1820) explains to how to manage the risks in construction and what actions you can take to comply with the law.

Managing noise from commercial and industrial construction sites

The Civil construction, building and demolition guide (publication 1834) provides information to help government and industry manage noise impacts from commercial construction sites. This guide is also relevant for demolition on commercial and industrial land, including when land is being redeveloped for residential use.

The Civil construction, building and demolition guide (publication 1834), advises normal working hours for commercial construction and demolition site noise are: 

  • weekdays – 7 am to 6 pm
