Full house rewiring is a significant job, and most homes never need it entirely – but some genuinely do. Here’s how to tell.
Signs your home may need rewiring
Frequent breaker trips with no clear single cause, warm or discoloured outlet covers, flickering lights unrelated to load shedding, an outdated fuse-wire DB board rather than modern circuit breakers, or wiring you know to be original to a home built before the 1980s are all signs worth a professional assessment.
Full rewire vs partial rewire
A full rewire replaces all wiring throughout the property – disruptive and costly, but sometimes genuinely necessary for very old installations. A partial rewire addresses specific problem circuits or areas (a kitchen renovation, a single faulty circuit) without touching wiring that’s still sound – the more common and more affordable outcome of an assessment.
What affects the cost
Property size, wall construction (chasing into brick costs more than a ceiling void), and whether it’s full or partial all drive cost – which is why we assess before quoting rather than giving a blanket per-square-metre price.
Frequently asked questions
Can I live in the house during a rewire?
For a partial rewire, usually yes with some disruption to specific rooms. A full rewire is more disruptive and sometimes easier to manage with the property vacant.
Does rewiring require a new Certificate of Compliance?
Yes, any rewiring work is certified once complete.
