Frequently Asked Questions

Got questions? We've got answers. If you can't find what you're looking for, give us a call.

Yes, for most standard residential and commercial jobs in Blenheim, we provide a free, no-obligation quote. For complex fault-finding or rural travel, we will let you know upfront if any costs are involved before we arrive.

We highly recommend it. Old rewireable fuses are a fire risk and don't offer the same protection against electric shock as modern RCDs (Residual Current Devices). Upgrading your switchboard protects your family and is often required by insurance companies.

Not at all. Whether you need a single broken power point fixed, a light bulb changed in a high ceiling, or a complete house or commercial rewire, our team is happy to help.

Yes. We work with landlords and property managers across Marlborough to ensure rentals meet the heating and ventilation requirements of the Healthy Homes Standards, keeping your tenants warm and your property compliant.

Yes. As registered electricians, we issue a Certificate of Compliance (COC) and Electrical Safety Certificate (ESC) for all prescribed electrical work. This is your proof that the work is safe and legally compliant.

The earlier, the better. Call us during the planning phase. We can help with lighting design and ensure the wiring is "roughed in" before the gib/lining goes on, saving you time and money later.

You can, but it is very slow and can overload older wiring. We recommend installing a dedicated EV charger. It's much faster, safer, and can be set up to charge during off-peak times to save you money on power bills.

Yes, we do. To meet Health & Safety regulations, all electrical appliances in a workplace must be tested and tagged regularly. We can schedule this for your office, workshop, or construction site.

LED lights use up to 85% less energy than traditional incandescent or halogen bulbs and last significantly longer. Swapping your whole home or office to LED is one of the most cost-effective ways to lower your monthly power bill.

Yes, we service the entire Marlborough region, including Picton, Havelock, and properties in the Sounds. For boat-access-only properties, please contact us to discuss logistics.

Yes, Wairau Electric is a member of Master Electricians NZ. This means all our work is backed by a $20,000 workmanship guarantee, giving you total peace of mind.

For jobs within the Blenheim town boundary, standard rates apply. For locations further afield (Renwick, Seddon, Picton), a standard travel charge is included in your quote so there are no surprises.
