Serving homes & businesses across Christchurch & Canterbury
Had a customer in Fendalton buying a house last year. The building inspector found heaps of non-compliant electrical work done by the previous owner — uncertified additions, dodgy wiring, no RCD protection. The sale almost fell through because the buyer's lawyer said it all needed fixing and certifying before settlement. Cost the seller $8,000 to bring everything up to code, when it could've been avoided if they'd used a licensed electrician originally.
Electrical code compliance probly sounds like boring paperwork but its actually super important. Whether your buying a house, selling one, doing renovations, or running a business you need proper electrical certification. Without it you can have serious problems.
Electrical code compliance means your electrical work meets New Zealand standards and regulations. All electrical work needs to be safe, done properly, and certified by licensed electrician.
The main standard is AS/NZS 3000 - the wiring rules. This covers everything about how electrical installations should be done. Cable sizes, circuit protection, earthing, testing, all of it.
Building code also has electrical requirements. Things like smoke alarms, emergency lighting, accessibility - these are building code not just electrical standards.
Only licensed electricians can do electrical work and issue certificates. Theres different license levels but all electrical work needs someone with right license signing it off.
Certificate of compliance gets issued after electrical work is completed. This goes to council and becomes permanent record that works been done properly.
Non compliant work is illegal and dangerous. It voids your insurance, creates safety hazards, causes problems when selling property, and can result in fines.
Certificate of compliance - COC for short - is official document that certifies electrical work meets code requirements. Every bit of electrical work needs one.
Licensed electrician who does the work issues the COC. We test everything, verify it meets standards, then issue certificate with our license details.
COC gets submitted to council within certain timeframe. Usually 5 working days after work is completed. Council keeps record in their system.
Property owner gets copy of COC. You should keep these with your house documents. When you sell the house buyers lawyer will ask for electrical certificates.
What COC covers - the specific work done, location, date, test results, electricians details. Its permanent record of that electrical work.
You need COC for pretty much any electrical work. New circuits, switchboard upgrades, additional power points, lighting changes, heat pump installation, hot water cylinder work - all needs COC.
Customer in Riccarton wanted to add some power points in their garage. A handyman mate offered to do it cheap. I explained they need a licensed electrician and a COC. They went ahead with the mate anyway. Two years later, when selling the house, the missing COC became a huge issue. Ended up paying me to inspect and certify the work — which cost more than doing it properly the first time.
People get confused about building consent and certificate of compliance. Theyre different things and sometimes you need both.
Building consent is council approval before work starts. Some electrical work needs building consent - rewiring a house, adding new main switchboard, significant alterations.
COC is issued after work is done. All electrical work needs COC whether it needed building consent or not.
Simple stuff like replacing power points or adding circuit usually dosnt need building consent but still needs COC.
Major work like house rewire or new connection needs building consent first, then COC after work is completed.
Licensed electrician knows whether your work needs building consent. We handle consent applications if required as part of the job.
When we inspect properties we find same code violations over and over. Most of them come from DIY work or unlicensed handymen doing electrical.
Older houses might not have RCDs and people add circuits without installing proper protection. This is dangerous and non compliant.
Someone adds heater circuit using cable thats too small. Cable overheats, insulation fails, fire risk.
Wrong size breakers, no earth fault protection, damaged breakers still in use.
Junction boxes without covers, damaged outlets showing bare conductors, light fittings with accessible live terminals.
Cable not protected properly, running through areas where it can be damaged, no mechanical protection where required.
No earth on metal components, earth wires not connected, earth path broken.
Active and neutral swapped which is dangerous even though it might seem to work.
Did an inspection on a rental in Papanui. Found an extension cord hardwired into the wall as a permanent installation, no earth on the bathroom light, an RCD bypassed cause it kept tripping, and cable running loose in the ceiling with no support. All of this was done by the landlord's handy person. We issued a notice prohibiting use til it was fixed properly. Cost the landlord heaps to rectify when a licensed electrician would've done it right originally.
If youve got non compliant electrical work it needs fixing. Cant just ignore it cause of insurance and safety issues.
We start with inspection to identify exactly whats wrong. Document all the code violations and safety issues.
Provide quote for rectification work. Sometimes its simple fixes, sometimes needs major work depending how bad it is.
Do the repairs to bring everything up to code. Might need new circuits, proper earthing, RCD protection, cable replacement - whatever it takes.
Test everything thoroughly. Insulation resistance, earth fault loop impedance, polarity, RCD operation - full testing to verify compliance.
Issue COC for the rectification work. Now theres proper certification showing systems compliant.
Some insurance companies make you fix non compliant work once they know about it. If theres claim and they find dodgy electrical they might not pay out.
House in Merivale had a garage converted to a sleep out by the previous owner. The electrical work wasnt certified. New owners got a building inspection when buying and it flagged the issue. We inspected and found heaps of problems - no proper earthing, cables run incorrectly, circuits overloaded. Had to basically redo all the electrical for that space properly and certify it.
If your buying property getting electrical inspection is smart move. Building inspector might spot obvious problems but detailed electrical inspection finds hidden issues.
We check the switchboard condition. Look for old equipment, signs of overheating, damaged components, missing protection devices.
Test RCDs actually work. Just cause theres RCD doesnt mean its working. We test with proper equipment not just the test button.
Check wiring is in good condition. Look in roof space, under house, visible wiring throughout. Old or damaged insulation is concern.
Verify earthing system is intact. Test earth resistance, check bonds are connected, ensure earth path is continuous.
Identify any obvious code violations. DIY work, unlicensed modifications, unsafe installations.
Review available electrical certificates. If sellers claiming works been done they should have COCs to prove it.
Provide written report of findings. This gives you ammunition to negotiate price or require fixes before purchase.
Inspection costs few hundred dollars but can save you thousands. Buyers in Bishopdale used our pre purchase inspection. We found the switchboard was dangerous and needed complete replacement. They negotiated $6,000 off the purchase price to cover the work — way more than what the inspection cost them.
Rental properties have specific electrical requirements. Landlords gotta make sure everythings safe and compliant.
All fixed electrical installations must be safe. This means no exposed wires, damaged outlets, faulty switches, broken light fittings.
Power points and lighting circuits need RCD protection in rentals. No excuses on this one.
Smoke alarms are mandatory and they need to be hardwired or have long life batteries. Battery smoke alarms need working batteries.
Any electrical work in rental needs proper COC. Landlord should keep records of all electrical certificates.
Healthy homes standards include some electrical requirements around heating and insulation which have electrical components.
Tenants can request an electrical safety check. If a tenant raises concerns the landlord has to get a licensed electrician to inspect.
We do heaps of rental property electrical compliance work — regular inspections for landlords with multiple properties, fixing issues tenants report, upgrading to meet healthy homes standards. A landlord in Sydenham has 8 rental properties and we maintain electrical on all of them. Annual safety checks, fix problems promptly, keep all documentation. Means her properties stay compliant and tenants stay safe.
Commercial properties have stricter electrical compliance requirements than residential. More regulations, more testing, more documentation.
Warrant of fitness required for commercial buildings. This includes electrical systems inspection and testing on a regular schedule.
Emergency lighting must be tested monthly and annually. Records of testing gotta be kept on site.
Exit signs need to work properly. Regular testing ensures theyre illuminated and visible.
Test and tag of portable equipment required. How often depends on environment but could be 3 monthly in some workplaces.
Complete electrical installation gets tested every few years depending on building use.
Fire alarm systems need regular testing and certification. This is specialized work but connects to electrical systems.
We maintain compliance for office buildings, retail spaces, industrial facilities across Christchurch. A business owner in Hornby hired us to handle all electrical compliance for their warehouse. We do annual fixed wire testing, quarterly emergency lighting checks, test and tag, maintain records, coordinate with the building warrant inspector. Takes the compliance burden off them.
Non compliant electrical work creates serious problems. Its not just theoretical - real consequences happen when works not certified.
Insurance wont pay if electrical fault causes damage and works not compliant. House fire from dodgy wiring might not be covered.
Property cant be sold without sorting compliance issues. Lawyers require electrical certificates for building transactions.
Council can issue notices prohibiting use of non compliant electrical installations. This means no power til its fixed properly.
Fines possible for uncertified electrical work. Councils can prosecute for building code violations.
Safety risk to occupants. Non compliant work is dangerous and people can be electrocuted or fires can start.
Commercial properties can lose building warrant of fitness. This means building cant be legally occupied til fixed.
Property value affected. Buyers factor in cost of fixing non compliant work when making offers.
Seen all these consequences happen. A house in Sumner had a fire from uncertified electrical work. Insurance investigated and found multiple code violations done by an unlicensed person. They denied the claim. The owner lost the house, and the insurance company sued them for fraud cause they'd claimed the work was done by an electrician on the insurance documents.
Staying electrical compliant isnt hard if you do things right from start. Just follow some basic rules.
Always use licensed electrician for electrical work. Dont use handymen, DIY, or unlicensed people no matter how cheap they are.
Get COC for every job. Make sure electrician provides certificate and submits it to council.
Keep copies of all electrical certificates. Store them with property documents so theyre available when needed.
Do regular maintenance and inspections. Catches problems early before they become compliance issues.
Fix problems promptly when theyre identified. Dont leave electrical faults til they get worse.
If buying property get electrical inspection. Know what your getting into before you commit.
For rental properties have annual electrical safety check. Keeps you compliant and tenants safe.
Commercial buildings follow warrant of fitness requirements. Keep up with testing schedules and documentation.
Ask questions if your unsure about electrical work. Licensed electricians can advise whether building consent needed, what compliance requires, all that stuff.
Electrical compliance work costs vary depending what needs doing. Heres rough guide to whats involved.
Basic work like adding a circuit — we do the work, test it, and issue the certificate as part of the service.
Depending on property size and complexity.
Minor fixes might be a few hundred dollars. Major rectification could be thousands.
Depends on age and what needs upgrading.
Small shop might be $500 for an annual test, a big building could be several thousand.
Typically charged per appliance tested.
Emergency lighting testing ranges from a couple hundred for a small setup to over $1,000 for a large commercial building.
