Generators OnLine has a comprehensive range of fuel services available.

Fuel Deliveries

Generators OnLine has its own fleet of fuel transportation and delivery vehicles. No matter the quantity or location, allow us to help with all of your diesel fuel requirements.

As well as satisfying delivery requests, following planned generator service visits, we provide current fuel level notifications along with advice based on fuel levels on the expected machine run times.

This advice comes complete with competitive quotations for planned top-ups.

In addition, we can provide emergency deliveries.

Fuel Sampling and Polishing

Low quality fuel can have a seriously damaging effect on a generator’s engine. If diesel sits unused for over eighteen months, bio degradable particulates are likely to build up. When this fuel is used, these particulates are dragged through the generator’s fuel system, causing blockages which become a stern cause for concern.

It is therefore extremely important to take regular samples of your fuel to combat against this.

If you want to avoid engine overhaul’s and replacements due to poor fuel quality, please call us to find out more about our fuel sampling and polishing services on 08000 855 944

Fuel Tanks

Selecting the size of an external fuel tank for your generator needs careful planning to ensure the tank you have selected suits your power demands. Generators OnLine offer a number of fuel tank solutions, ranging from 1000 – 30,000 litre tanks.

We highly recommend a site survey to allow us to advise you on the correct combination of fuel storage and transfer equipment prior to your purchase.


If you place an order with us after purchasing a site survey, you will receive a £250 discount.*

*If site survey is for supply of tank only, discount to apply only in conditions whereby site demands a 1000L + fuel tank.
