Common Questions

Alterations & Renovations — FAQs

Does Electrical Work for an Alteration or Extension Need to Be Inspected?

Most rewiring, new circuits and switchboard changes are prescribed electrical work, which means it must be done by a licensed electrician, tested and certified. We complete the required testing and issue a Certificate of Compliance for the new work. Where high-risk work is involved an independent inspection may also be needed, and we will tell you if that applies to your job.

Can You Tie New Wiring Into the Existing Wiring in My House?

Yes, that is a big part of renovation work. We assess the existing system first, then design the new circuits to integrate safely with what is already there. Older homes around Dunedin sometimes have wiring that is past its best, so if we find anything unsafe we will flag it and explain your options rather than quietly building on top of a problem.

What Affects the Cost of an Alteration or Extension?

Cost depends on how much new wiring is needed, whether your switchboard can handle the extra load, the number of new points and lights, and the state of the existing wiring. Wet areas like kitchens and bathrooms need dedicated circuits and RCD protection, which adds to the work. We assess the job on site and give you a fixed-price quote before we start.

How Disruptive Is the Work and How Long Does It Take?

It depends on the scale. Adding a few points or modernising lighting can be a day or two, while a full extension wired alongside a renovation runs longer and is staged with the builder. We coordinate with the other trades to keep disruption down, work tidily, and let you know the timeline up front so you can plan around it.

Do I Need to Upgrade My Switchboard During a Renovation?

Often, yes. Older fuse boards frequently lack the capacity and RCD protection for modern demands like extra appliances, heat pumps or EV charging. A renovation is the natural time to upgrade. We will assess whether your board can take the new load and recommend an upgrade only if it genuinely needs one.
