Where is Cosine based and what areas do you cover?

Cosine Electrical is based at Waerenga in the North Waikato, between Te Kauwhata and Morrinsville. We cover the wider Waikato and South Auckland — from Manukau down to Te Awamutu, east to Thames, west to Raglan. Drive times from Waerenga: Hamilton 30-40 minutes, Cambridge 40 minutes, Pukekohe 30 minutes, Manukau 45 minutes, Raglan 75 minutes, Thames 60 minutes.

What is the digger operator on the crew thing?

Most electricians sub-contract digging for underground work — second contractor, second quote, second site visit. Cosine has a skilled digger operator on the crew, so for underground jobs we trench our own runs. One quote, one team, one site visit. Note: Cosine is not a registered drainlayer. Wastewater and stormwater scope sits with a licensed drainlayer.

How quickly do you get back with a quote?

Within 24 hours of the site visit. Itemised, in writing, valid 30 days. For smaller jobs we can often give a rough indication over the phone if you text photos of the existing setup.

What does a switchboard upgrade cost?

A straight switchboard upgrade in an average three-bedroom Waikato house is typically $1,500-$2,500 plus GST for board and labour. Push-ups: old cable failing insulation tests, mains upgrade needed (lines company involvement), asbestos in the meter-box backing board common in 60s and 70s houses. Everything flagged in the written quote — no surprises on the invoice.

What does an EV charger install cost?

Standard install with the existing switchboard up to spec is $1,200-$1,800 plus GST plus the charger. Older home needing a board upgrade adds $1,500-$2,500. Long trenched runs to a detached garage on a lifestyle block typically $2,500-$4,500 all-in.

Do you do compliance testing for landlords?

Yes — landlord WOF-equivalent inspections, RCD function tests, written reports with photos and plain-English findings. Insurance-ready paperwork.

Do you work with builders on renovations?

Yes — preferred sparky for several builders across Hamilton, Cambridge and Pukekohe. We walk through with the homeowner and builder before quoting, mark up the plans, and work to the builder's schedule. We don't hold up the next trade.

Can you handle commercial maintenance for property managers?

Yes — scheduled maintenance contracts, emergency callouts, fault-finding, compliance reporting. One number, one paperwork system, no padded packages and no lock-ins.

Do you certify the work?

Always. Every new circuit and every board upgrade gets a Certificate of Compliance emailed through within a day of the job finishing. Required for insurance, future sale and any audit.

What if you cannot fix a fault in one visit?

Some faults like earth leakage on a circuit shared by multiple cables genuinely need a second visit. Day 1 we isolate the faulty section onto its own RCBO so the rest of the house keeps power. Day 2 we test and replace the bad section. We don't punch holes in walls to brute-force the search.

Huntly's heating profile is the most budget-conscious in our service area, and the heater install conversations reflect that. We work Huntly from our Waerenga base, about 15 minutes away.

What a WiFi heater install actually involves

Plug-in — quick.
New socket + plug-in — for when the socket isn't in the right place.
Permanently wired — required for higher-wattage units, bathrooms.

What's specific to Huntly WiFi heater installs

Older switchboards are the bottleneck for permanent installs. Many Huntly homes have ceramic-fuse boards. Board upgrade or RCBO add often needed first.
Budget Goldair units work for secondary rooms. A Goldair 1.5kW on an existing socket will heat a bedroom fine at a third the price of premium.
Working-class budgets mean honest scoping. We tell you what the job actually needs.
Small-job-friendly because we're local. Single-heater installs are fine.
Multi-heater installs in family homes when budgets allow — usually Redwood across bedrooms and living.
Lifestyle blocks toward Glen Afton and Pukemiro — larger homes, more heaters, sub-board work.

Brand options

Goldair (budget), Redwood WIFI V2 (middle-ground), Rinnai (premium), Devola, Bromic.

Honest comparison: Goldair is fine for occasional use; Redwood is the day-in-day-out workhorse; Rinnai is premium.

What it costs

Single plug-in $150-$250. New socket + install $300-$500. Permanent wired $400-$700. Multi-heater (3-5 rooms, one visit) $900-$1,500. Switchboard upgrade adds $1,500-$2,500.
