Why Generator Maintenance is Important

Hopefully, your backup is barely given a second thought, but in the event of a power outage, you need to ensure that your standby is ready and capable to do its job and keep you operational should the worst occur.

Our bespoke generator service packages are designed to ensure that your generator will be able to support you when needed. You can fully customise our cost-effective plans to ensure you are paying for a service that meets your needs.

The cost of maintaining your generator should be minimal compared to if you have a power outage and your generator does not kick in, preventing your site from being operational. Generators are not cheap pieces of equipment to install so ensuring your generator is well-maintained will ensure you get the most from your investment.

Regular servicing will improve the lifespan of your standby generator and provide a longer hassle-free lifespan. Diesel generators are a great efficient and cost-effective solution for your backup power supply but need regular minor service and upkeep tasks completing to ensure they are performing as they should.


  • Save on big repair bills (More cost-effective)
  • Increases generator life span
  • Retains component warranties
  • Helps when it comes to insurance
  • Ensures compliance and safety
  • Reduces hassle

Generator Repairs with Vital Power

At Vital Power we offer nationwide generator repairs for businesses in a variety of industries. Generators require fairly regular servicing and maintenance check ups to ensure everything is working in top condition and ready to kick in when you need it to, but even with regular checkups sometimes repairs can be necessary.

The members of our fully trained team have years of experience working with businesses across multiple industries, so we understand how critical it is to get repairs done quickly and efficiently. We’ll work around your working day to minimise disruption, and can provide working repairs with short turnarounds.

Why Are Generator Repairs Necessary?

As with any piece of electrical or industrial equipment, diesel generators do suffer from wear and tear and can break down over time. Therefore, generators require regular check ups to make sure all parts are working correctly and there are no outstanding repairs.

Because generators work with a diesel tank, there are also potential issues with things like corrosion, rust, burnout and fuel contamination.

Some of the common generator problems and reasons equipment can fail include:

  • Overuse
  • Low fuel levels
  • Contaminated fuel
  • Controller failure
  • Sensor malfunction
  • External fluid hose failure
  • Voltage regulator failure
  • Blocked fuel filter

Because backup and emergency generators aren’t on all the time, it can be easy to miss issues like these until it’s catastrophically late. If you’re on a service contract with us, you also get access to our 24/7, 365 day emergency support line which you can use at any time to report issues with your equipment. Our team work quickly to ensure your equipment is back online and able to support your site in your time of need.

Got a question? We’re always happy to help.
