Building Information: Working in the Roof Space

Published on Thursday, 31 August 2023 at 8:48:50 AM

Following the recent and tragic fatality involving an electrical worker in a roof space, Building and Energy is issuing a reminder to always switch off the mains power before entering a roof space.

The roof space of a home can be a dangerous area. Roof spaces can present serious electrical hazards and the potential for electric shocks is high.

Under WA’s Work Health and Safety Regulations, it is mandatory for the mains power to be off before any worker enters the roof space of a Class 1, 2 or 10a building (generally being residential dwellings, apartment buildings or related buildings such as a shed, carport or private garage).

This applies to all workers, not just electrical workers, and homeowners, who intend to enter the roof space.

For more information, please refer to WorkSafe's Guidance note – Working in roof spaces.

If you plan on working in the roof space, your first step is to switch off the electricity at the main switchboard/meter box by turning the main switch to the "OFF" position.

Building and Energy is now distributing free safety stickers to be placed on manholes and switchboards as a reminder to turn off the main switch at the property’s switchboard or meter box before entering the roof space.

The free stickers can be requested by emailing:
