Power You Can Trust



It’s a well-known fact in the power generation industry that generators running on diesel are much more durable and reliable than their petrol counterparts. However, this sometimes leads to a complacency among businesses, who choose not to obtain a generator maintenance contract with a specialist, or even perform any basic in-house checks. If you take one thing away from this article, we want it to be that purchasing a generator maintenance services is a wise and sensible move.

You may also need to consider maintaining your UPS (uninterruptible power supply) if you have one. A UPS is designed to bridge the gap allowing time for an electrical system to shut down and time for a generator to take load or mains electricity to return – helping to stem any damage done or loss of data. At WBPS, we understand the requirement for critical power to remain fully operational is extremely high and this is intensified by new technology and the increased power demands.

By caring out regular, rigorous testing, and by being proactive in your general maintenance, you’ll be able to identify problems before they happen or when they are smaller and easily rectified. Ultimately, this will save your company time, money, and stress.


This goes hand in hand with problem number two. To keep costs low, we thoroughly recommend getting repairs done as and when they are identified. Waiting or delaying on these repairs is only going to offer fertile ground for larger problems to grow, which is going to cost you much more, especially if the minor issue causes problems in other parts of the engine. Upfront repair costs can sometimes be high enough to put people off. It can be tricky, but it’s important that people look at the big picture in this situation and try to think about the much larger costs in the future if they don’t act now!


One thing we regularly see in our industry is people seeing a minor issue as something that can be left until the next service, which could be months or even years away in some circumstances. In our expert opinion, this is not a good idea, you will be surprised how quickly some issues can escalate!

You may consider the advised repair to be unnecessary, but the one guarantee #teamwb can give is that by doing it straight away, you will avoid larger repair and increased costs.


No matter what application your generator is running on, whether it’s prime, standby or continuous, if you don’t undertake recommended repairs, you run the risk of a generator breakdown. Simply deciding to complete the repairs quickly when they are identified will provide you with peace of mind that your generator is running at full efficiency. On the flip side, ignoring repairs can greatly lower the overall performance levels of your generator, leading to a noticeable drop off in its capabilities and power output. Common examples include:

Not regularly replacing fuel filters may lead to clogging from a variety of different substances, causing serious damage to the engine.
Not changing fluids such as oil and coolants can lead to a build-up of debris, causing blockages and damage.


Some industries may have stricter compliance legislation, meaning that a generator which hasn’t been serviced is not compliant, leading to heftier bills in the event of a breakdown. Your generator manufacturer may also refuse to replace your generator in the event of an engine failure if the generator hasn’t been regularly serviced.

When searching for generator maintenance suppliers, it’s critical that you find out exactly what is included in your package. Additional services such as load banking, fuel testing, and automatic transfer switch maintenance may not be a standard element to the maintenance agreement and may need adding on.


This one is very simple. In the event of a mains power outage, do you really want to be faced with a broken-down generator too? Or would you rather be safe in the knowledge that your fully serviced standby generator is going to run perfectly?
