How Much Does It Cost to Rewire a House in Perth? 2024 Guide
If you’re considering rewiring your Perth home, understanding the costs and factors involved is crucial for planning your budget. While prices vary based on numerous factors, this guide will help you understand what influences rewiring costs and when it’s necessary.
When Does Your House Need Rewiring?
Before discussing costs, it’s important to know if your home actually needs rewiring. Consider rewiring if your house has:
Age-Related Issues
- Wiring over 40 years old
- Cloth-insulated or rubber wiring

Warning Signs
- Frequently tripping circuit breakers
- Flickering or dimming lights
- Burning smells from outlets
- Sparks from switches or outlets
- Two-prong outlets only
- Warm or discoloured wall plates
- Lack of ground fault circuit interrupters (GFCIs)
Factors Affecting Rewiring Costs in Perth
1. House Size and Layout
The square footage and number of rooms directly impact costs:
- Single-storey homes are generally less expensive
- Multi-storey homes require more labour
- Open floor plans may reduce costs
- Heritage homes often cost more due to preservation requirements
2. Accessibility
How easily electricians can access your wiring affects labour costs:
- Crawl spaces vs. finished basements

3. Electrical Load Requirements
Modern electrical demands influence the scope of work:
- Number of power points needed
