Diesel Generator Installation

Having a diesel generator as part of your business operations is crucial for many businesses

Installing Standby Generators

From data centres and universities to hospitals and agricultural facilities, your backup generator set can be an essential form of power in the case of a mains outage or other electrical failure.

Having a power outage contingency plan in place can be the difference between a successful day of trading and having to shut down your entire operation due to no electricity. So, the first step might be thinking about how to choose the right generator for your business, but next you’ll need to plan how you’ll install any potential standby generators.

How do diesel generators work?

Before you start the actual process of planning your generator installation, there are a few important decisions that need to be considered. These include plans as to how beneficial the backup power option for your business will be, how you can ensure the safety of your workers who will be operating around it, and what processes you’ll have in place.

At Vital Power our team of generator experts can help you plan every eventuality and provide industry-leading expertise to help. Once you’ve got your fuel system decided, you’ll need to plan out how and where it will be installed on your premises.

These are some of the factors to consider ahead of generator installations…


There are a number of options available to you in terms of where you’ll place your generator. For businesses considering having multiple generators installed, exterior spaces are usually best. You’ll need to think about the amount of space you have available, as well as where the best location for integrating with your power system.

Should you opt for indoors, you will need to think about ensuring there’s plenty of quality ventilation. Generators, naturally, can get hot – so for safety and security you need to make sure there’s plenty of space all around the generator’s vents.

Should you choose the outdoors for locating your generator, there are other considerations to make too. For example, there will be a need to plan for protection from the elements – keeping your generator free from adverse weather conditions like storms, rain, snow and sleet. You’ll also need to think about security and protecting elements like the transfer switch or generator control system.


As well as purchasing from an approved provider like Vital Power, there are a few other bits of admin you need to take care of when installing a generator at your business. A permit must be obtained before installing – a generator permit or generator licence is typically offered by either your local council, or an insurance provider. This is a legal requirement, and as such, cannot be overlooked.

The team at Vital Power can help advise you on getting the correct generator documentation, in addition to showing you the best and safest options for your business from our range of leading manufacturers.


Having a concrete pad for your generator is essential. This is a vital step in ensuring that your company’s establishment is primed for your diesel generator installation. A concrete pad not only helps your generator set – a valuable investment for any business – stay safe and remain in good condition. It also protects the welfare of your employees and any contractors who may help service your generator. The concrete pad safeguards your unit against the threat of standing water, which can cause considerable damage to electrically-powered appliances. It will also keep it anchored in place for years to come.


It’s important to note that diesel generators require regular service and maintenance, as well as refuelling. Our generator installation service engineers will need to access all parts of the generator, so ensuring the set is installed in a good position is vital to its future health.

All Vital Power generators housed outdoors come with a weatherproof canopy as standard. These canopies contain service doors which allow for easy access to all parts of the generator to be serviced. Ensuring that these doors are easily accessibility for our engineers is crucial.

Not to worry though, our team handle all aspects of the installation project. From the initial consultation on site, to installation and commissioning, to future service & maintenance works, we’ve got you covered.

As part of our generator sales service, our team can help advise on placement, size and more.
