Preston’s mix of older brick homes, renovated weatherboards and subdivided units can mean patched-in wiring and switchboard upgrades of varying quality. A polarity-focused assessment helps spot dangerous miswires before they turn into shocks, appliance damage or nuisance tripping.

Our comprehensive service includes everything you need to make an informed decision about your property.
We test selected, accessible power points to confirm active/neutral polarity and identify miswired outlets. Reversed polarity can make appliances and switches unsafe because parts that should not be live may become energised.
We visually assess the switchboard for safety concerns such as aged components, signs of overheating, poor labelling, and unsafe access. A tidy, correctly protected switchboard supports safer fault isolation and reduces fire risk indicators.
We check whether RCD protection appears to be in place and test operation where accessible using the test button and/or appropriate methods. RCDs are critical for reducing the severity of electric shock, especially in wet areas and general power circuits.
Where wiring is safely visible (for example at the switchboard or in accessible areas), we look for warning signs like brittle insulation, unsupported cabling, makeshift joins, or damage that may suggest the need for electrician attention.
We check for installed smoke alarms, note their location and visible condition, and identify obvious issues that may affect performance. Smoke alarm requirements can vary depending on building work and layout, so we highlight where an electrician should verify compliance.
For properties with extensions, updated kitchens, or backyard studios, we note practical indicators of how circuits may be split or added. This helps you ask the right questions about what is protected by RCDs and what may still be on older, less protected circuits.

Find answers to the most frequently asked questions about our inspection service.
Many Preston properties have had incremental electrical work over decades, including renovations and extensions. Polarity errors can occur when outlets or switches are reconnected incorrectly, and they’re not always obvious until a fault occurs. A polarity-focused assessment tests selected accessible outlets and checks related safety controls like RCDs and switchboard condition, so hazards are identified early and can be corrected by a qualified electrician.
No. Our Electrical Safety Assessment is an inspection and testing service designed to identify hazards and safety concerns, including polarity issues, RCD operation and switchboard red flags. Any repairs, upgrades or compliance certification must be completed by a licensed electrician. We provide clear findings you can take to your electrician so they can quote accurately and address the highest-risk items first.
We focus on practical, safety-critical areas: selected accessible power points for polarity, the switchboard for visual safety concerns, and safety switches (RCDs) for presence and operation where accessible. We also note visible wiring issues and check smoke alarms for presence and obvious concerns. Areas that are unsafe or not accessible without invasive work are noted, with recommendations for electrician investigation if needed.
Renovations can leave a property with a mix of old and new circuits, sometimes with inconsistent RCD protection and variable workmanship across outlets. Common concerns include reversed polarity at replaced power points, older circuits left in service for parts of the home, and switchboards that have been partially upgraded. This assessment helps pinpoint where the risks are and what a licensed electrician should verify or rectify before move-in.
We check whether safety switches (RCDs) appear to be installed and we test operation where accessible, and we also note the presence and visible condition of smoke alarms. Because rental and compliance obligations can depend on the dwelling type and any building work completed, we treat this as a safety assessment and provide guidance on what to confirm with a licensed electrician to meet the applicable requirements.
