Commercial Electricians in Invercargill

Commercial electricians in Invercargill provide services including shop and office fit-outs (lighting, power, data), three-phase power installation and upgrades, commercial lighting design and installation (LED upgrades, emergency lighting), switchboard upgrades and sub-boards for commercial premises, electrical warrant of fitness (EWOF) testing and certification, data and network cabling, and planned maintenance programmes. Commercial work often requires after-hours access to minimise disruption to the business.

In New Zealand, certain commercial and rental buildings require an Electrical Warrant of Fitness (EWOF) under the Electricity (Safety) Regulations 2010. Buildings that require an EWOF include commercial premises with employees, rental properties (residential and commercial), and buildings with fixed wiring over 50 years old. An EWOF inspection checks the safety of the building's electrical installation. A registered electrical inspector must carry out the inspection and issue the warrant. EWOFs are typically valid for one to five years depending on the installation.

Upgrading commercial lighting to LED is one of the best energy-saving investments for a business. Commercial LED upgrades typically reduce lighting energy costs by 50 to 70 percent and the new fittings last five to ten times longer than fluorescent tubes. A typical small office or retail LED upgrade costs $2,000 to $8,000 depending on the number of fittings. The payback period is usually one to three years through electricity savings. Some electricity retailers and EECA offer rebates or incentives for commercial LED upgrades.

Commercial electrical work must comply with AS/NZS 3000 wiring rules, NZ Building Code, and workplace health and safety requirements under the Health and Safety at Work Act 2015. All work must be done by an EWRB-registered electrician. Emergency lighting and exit signs are required in commercial buildings and must be tested regularly (six-monthly function tests and annual duration tests). Certificates of Compliance are required for all new electrical work.
