Servicing and Maintenance

Like any machine, your generator needs to be maintained to ensure that it delivers power when you need it most. Energy Generators offer several maintenance packages at great prices, with benefits that you won't find anywhere else.

With our base in Aylesbury, Buckinghamshire, we can reach large parts of Southern England within a few hours - including Central London, Birmingham, Oxford and Milton Keynes. Our team are highly trained and carry top quality testing equipment and spare parts to keep your generator in tip-top condition.

Generator maintenance contract with load testing

 

Annual and 6-month servicing

You wouldn't (or shouldn't!) go longer than a year without servicing your car, and that goes for your generator as well - even if it doesn't run for many hours throughout the year. A regular 6 month service interval will ensure that your generator remains reliable and ready for use when you need it. An annual service is the minimum that we recommend, and as is standard in the industry, we can't offer our emergency call-out service if your generator is not serviced at least annually.

Load Bank testing 

As part of a service or as a standalone procedure, Energy Generators can offer customers a load bank test on their generator. The equipment used to conduct a load bank test produces artificial loads on the generator by bringing the engine to an appropriate operating temperature and pressure level. This is especially important for standby and emergency generator sets that do not run very often and/or may not be exposed to carrying heavy loads on a frequent basis.  The general rule is - if your generator is not exposed to higher than 30% of its rated kW load then you should be considering a load test.

A generator that goes for long periods without a load bank test (if run at sub-optimum levels) will almost certainly gather a build up of carbon deposits which clog up the engine and can cause serious damage. A regular load bank test will clear these deposits, as well as highlighting any other areas where the generator needs attention.

There are many reasons that generators should undergo a load bank test on an annual or bi-annual basis, including the following:

  • Verifies the gensets capabilities opposed to just routinely starting it up
  • Problems discovered early can be significantly less expensive and prevents future major issues
  • Helps to avoid wet-stacking and cleans out carbon deposits
  • Verifies the engine cooling systems will perform while under load
  • Provides assurance that the genset should work properly when you need it most

Emergency call out - 24/7, 365 days a year

Our central location means that for the majority of our clients we offer a 2-4 hour emergency call-out service, which can include us bringing along a backup generator should we not be able to fix the issue.

Most backup generators rarely get used, and without regular servicing and checks they can generate problems instead of power! Of course we recommend that your generator is regularly checked and serviced, but we also offer packages that include us being on your doorstep with a replacement generator in the blink of an eye. Our engineer will attempt to fix your generator in the first instance, but if it's something that can't be fixed straight away, they will hook-up our replacement generator and that will stay with you for as long as is required.
