Affordable Electrical Commercial Maintenance in Auckland

A thorough preventative commercial maintenance programme is vital if your business or commercial premises are to limit electrical faults, downtimes and hazards. With the Grammar Electrical™ team as your dedicated electrical partner, you can rest assured your commercial facility is safe and productive thanks to our regular and responsive monthly electrical maintenance programme – we also perform one-off electrical maintenance checks.

Our comprehensive electrical maintenance schedules are tailored to the age and complexity of your building’s electrical system; we currently maintain many commercial buildings throughout Auckland, including commercial premises, office blocks, factories, schools and apartment blocks.

Our electrical maintenance contracts for commercial buildings includes:

  • Fault diagnosis & troubleshooting
  • Comprehensive electrical safety inspection
  • Emergency lighting & exit lighting testing
  • Load testing & RCD testing
  • Lamp replacement & LED upgrades
  • Switchboard testing using the latest thermographic technology
  • Switchboard upgrades where necessary
  • Automated lighting control
  • Timeclock resetting & sensor resetting, e.g. after daylight saving
  • Electrical equipment test & tag

We are also a Registered IQP (Independent Qualified Person), meaning we can complete and sign-off your business’s regular electrical compliance checks.

Benefits of Regular Maintenance Contracts with Grammar Electrical™

A regular commercial maintenance contract with Grammar Electrical™ makes sense for the following great reasons:

Save Money with a Monthly Electrical Contract

A regular commercial maintenance contract on your commercial building or business is like an insurance policy. When something goes wrong with your electricity it can result in costly downtime or, even worse, can be a safety concern. It makes sense to maintain electrical equipment to prevent breakdown.

Increase the Life of your Electrical Equipment

Like a car or any other asset, your commercial electrical equipment will last longer if it’s properly maintained, and that requires a regular check-up from one of our trained commercial electricians.

Dedicated Service Schedule

To properly care for your electrical equipment, it pays not to be hit-or-miss. A monthly electrical service contract means we manage your routine maintenance, ensuring everything is checked according to a strict cycle that means safety and reliability of your equipment is ensured.

Efficient and Affordable Commercial Electricians

Partner with Grammar Electrical™ for your monthly electrical service contract and you will have one of our EWRB-registered commercial electricians assigned to your building. We build up site-knowledge and a special relationship with your building manager. It saves time and provides continuity of service.

24/7 Support

We offer our customers 24/7 support (excluding public holidays). That means you can phone Grammar Electrical™ any time of the day or night and someone will take your call and discuss what steps we can take to ensure an absolute minimum wait for your electrical and IT servicing.

‍
