Canterbury’s mix of older family homes and renovated extensions can hide reversed polarity, ageing switchboards and DIY cabling—issues that matter most where kitchens, laundries and outdoor circuits have been updated over time.

Our comprehensive service includes everything you need to make an informed decision about your property.
We test polarity at accessible power points to identify reversed active/neutral or wiring faults that can make appliances and metal fittings unsafe. Polarity issues are particularly important in renovated areas where older wiring meets newer work.
We assess the switchboard’s overall condition, signs of heat stress, labelling, and the presence/type of protective devices. This highlights whether the board is appropriate for modern loads common in Canterbury homes, such as high-demand kitchen appliances and heating/cooling upgrades.
Where RCDs are installed, we check for correct presence on relevant circuits and test operation using the test function. RCD coverage is critical in wet areas and outdoor circuits, where faults can escalate quickly.
We inspect accessible cabling and visible connections for warning signs such as damaged insulation, unsupported runs, exposed conductors, and non-compliant junctions. These issues commonly appear where extensions, underfloor work or garage conversions have been carried out.
We focus on electrical safety indicators in wet areas, including outlet condition, placement and protection considerations. These rooms are frequently remodelled in Canterbury homes, so we pay close attention to mismatch between newer fit-outs and older electrical infrastructure.
We confirm smoke alarms are present and note obvious suitability concerns, such as missing units, poor placement indicators, or outdated alarms. This supports practical compliance readiness and day-one safety for new occupants.

Find answers to the most frequently asked questions about our inspection service.
Many Canterbury properties have been upgraded in stages, so newer kitchens, extensions or outdoor circuits may connect into older wiring or switchboards. That mix can create polarity faults, missing RCD protection on certain circuits, or workmanship issues from past alterations. An Electrical Safety Assessment checks accessible outlets, the switchboard and key safety items so you can address hazards before they cause shocks, equipment damage or repeated tripping.
No. Our assessment identifies safety risks and red flags, including polarity issues, switchboard concerns and RCD presence where accessible. Any repairs, upgrades or formal certification must be completed by a licensed electrician. If we find issues, we’ll explain what to ask an electrician to inspect or rectify so you can move forward with clear direction.
We test accessible power points for polarity, review the switchboard condition and protective devices, check safety switches (RCDs) where fitted, and inspect visible wiring for damage or non-compliant connections. We also confirm smoke alarm presence and note obvious suitability concerns. The scope focuses on safety and practical risk reduction, not invasive testing behind walls or ceilings.
We look for signs the switchboard hasn’t kept pace with the home’s current electrical demand, including poor labelling, ageing components, heat stress indicators and inadequate protective devices. We also note whether safety switches appear to cover the circuits most relevant to modern use, such as wet areas and outdoor power. If the board looks dated or inconsistent, we’ll recommend electrician follow-up.
Yes, especially if the home shows signs of extensions, a modern kitchen in an older building, or multiple outdoor circuits. Electrical issues can be expensive and time-sensitive, and polarity faults or missing RCDs are safety-critical. Booking early gives you time to understand what needs urgent rectification, what may require switchboard upgrades, and how to factor electrical work into your purchase decision.
