Inspected, tested and approved
so you can buy with confidence.
Buying a used generator need not be a gamble. FW Power has 25 years of experience in diesel generators both in the UK and overseas. We are committed to providing only the highest quality used diesel generators, which is why all of the used generators we sell undergo a 75 point service inspection check and a full load test prior to despatch. Consider it to be like an MOT and test run but in much more detail covering all aspects of the operation and function of the generator.
With new stock arriving each week please contact us should you not be able to find the…
second-hand generator you are looking for. We also offer a wide range of new diesel generators from globally renowned brands such as Perkins, Cummins and Doosan.
All of the tests that we undertake on our used generators are all recorded, with every repair item and recommendation clearly detailed on the test sheets – a copy of which is given to the customer.
How can we be confident that the diesel generator you purchase from FW Power is the best quality second-hand generator that you can buy? Well, above you can see the test sheets that we complete and below is a summary of some of the key areas we test and inspect:
- Shutdowns tested at least 3 times during our test process.
- Physical connections to the base frame, radiator and alternator inspected.
- Charge alternator tested.
- Fuel pump inspected, fuel solenoid checked, fuel linkages lubricated.
- Fuel hoses inspected.
- Filters changed as required and air filter assembly checked.
- Oil tested and changed as required.
- Low oil pressure and engine temperature.
- Fan belts inspected, recorded and changed as necessary.
- All hoses checked.
- Fan blades and radiator fins checked.
- Radiator checked for fin blockage and cleaned as required.
- Coolant tested and changed as required.
- Fan guards checked and rectified.
- Radiator cap checked operationally.
- AVR checked and tested.
- Physical connections to the engine and base frame tested.
- Internal inspection of slip rings and diodes completed as required.
- Megger test if required.
- Display checked.
- Warning lights and instrumentation checked.
- Fuses, relays and cables inspected.
- Panel settings for autostart and any timers recorded.
- Auxiliary inputs recorded.
- Circuit breaker checked for correct operation.
- Batteries checked and changed as required.
- Battery charger and jacket water checked if applicable.
- Exhaust system checked.
- Exhaust condensate checked and drained.
- All generators tested at 25%, 50%, 75% & 100% of rated load.
- 50% load acceptance/load rejection tests completed and recorded.
- Voltage and Frequency variation on load recorded.
- Voltage and Frequency stability on load recorded.
With all of the above tests completed it is no wonder that FW Power are the number one choice when it comes to used diesel generators in the UK for large and small business alike.
FW Power sells all makes of generators such as FG Wilson, Perkins, Cummins, CAT, Volvo, Doosan, MTU, John Deere, Scania plus many more.

Diesel Generator FAQ
What basic checks can I do on my generator to keep it running smoothly?
It is vital to regularly check your generator to prevent breakdown. Below are some simple observations that can help keep your generator running smoothly (please note any further works should only be carried out by an experienced generator engineer):
Why should I choose a Diesel Generator?
A common misconception is that diesel generators are dirty, environmentally unfriendly and even expensive to run. Thanks to the invention of red diesel and advancing technologies, diesel generators can now run extremely efficiently and be a very cost-effective option. The simple answer to the question, however, is that a diesel generator is the most reliable backup power source currently available for extended running periods. Generators can start up in seconds providing a steady stream of power continuously.
What is KVA?
Generators are rated by kVA, this indicates how much power the generator can produce. Mechanical engines are rated in KW’s or Horsepower. kVA = Kilo Volt Ampere. 1 kVA= 1000 Volt Amperes (VA). A VA is the voltage times the current feeding an electrical load. 1 kVA = 08 KW’s (electrical) If you are unsure of what power requirement you need FW Power offer a simple guide to sizing or if the application is more complex we can attend site and look at sizing for you.
What is Load Bank Testing?
A load bank is a portable device that is used to mimic the load on a generator. A load bank tests the generators operational performance at every stage i.e. 20%, 50%, and up to 100% load. This ensures the generator is capable of doing what it is required to do when the need arises. It is a crucial test for standby generators, especially as faults can be identified and rectified before the time arises when you need your generator.
What is the difference between three phase and single phase?
Single phase : Consists of 3 cables: Live, neutral and earth. Typically the voltage is 220-240 Volts. Domestic houses have single phase supplies. Current will flow through only the live wire and there will be one return path (neutral) to complete the circuit. Three phase : Consists of 5 cables: 3 live ( L1, L2 & L3), a neutral and an earth. Typical voltages are 400-415 Volts between the live cables ( eg. L1-L2) and 200 -240 Volts between the live and neutral. hence a three phase system is often given the voltage as 415/240V. Both single phase and three phase power systems refer to units using (AC) alternating current electric power.
