Bulk Fuel Tanks


Bespoke Tanks by Advanced

If you require a basic bulk fuel storage solution or a fuel system as part of a wider project, your fuel tank will be fully integrated and maintained as part of the generator system. All our bulk fuel tanks are self bunded as standard, with the options of 'pipe in pipe' and duplex-pumped fuel feed and return systems. General fuel system specifications

Additional fittings are available.

The following come as standard on all Advanced Fuel Tanks;

  • Filler
  • Hydrostatic contents gauge
  • High & low level alarm
  • Bund alarm


Bulk Fuel Tank Benefits


  • Pressure tested plate steel construction
  • Corrosive resistant tank & fittings
  • Mechanical fuel level monitoring
  • Outer tank/bund, leak detection
  • Building management system integration
  • Remote warning & monitoring options
  • Fire safety systems, including fuel dumping
  • DEFRA compliant fuel tanks
  • Built to the British Standard for fuel storage
  • Single skin or steel bunded fuel tanks


Compact Storage

Capacity: 2,000 to 30,000 litres Steel Bunded fuel storage tank with locking fuel fill cabinet and locking links cabinet for electrical connections.

Bespoke Options

Bulk fuel tank: Control and filtering Bespoke options for Compact or Roller Shutter type fuel tanks, Options can include fuel filtering and remote management.

Roller Shutter Storage

Capacity: 10,000 to 50,000 litres UK specification bunded fuel storage tanks with locking roller shutter door, housing the fill point, fuel filters and electrical links etc.
High and low level monitoring is included as standard and can act as an early warning alarm in such events as low fuel level fuel tanker overfill and excess ingress to fluid to the bund area. Once connected to a building management system, all the data from the fuel tank sensors would be relayed to the control room for accurate, up to the second monitoring.

Fuel Tanks for Diesel Generators

We all know the basics of how generators work to supply primary or back-up power. An engine turns the chemical energy stored in fuel into mechanical energy – Usually turning a shaft. That shaft then turns a generator, which takes that mechanical energy and converts it to electricity that can easily be used for any number of purposes. However, the whole process begins with a ready fuel supply, in this case a high capacity diesel tank.

Diesel fuel tanks are not mere drums, though. Each is specially designed for safety, capacity, convenience and ease of maintenance. Different models also have differing features and strengths. This guide helps you understand what factors you need to consider when selecting a furel tank for your diesel power generator.

What Capacity will you need?

The most salient feature of any fuel tank is its capacity. After all, if it does not hold enough fuel, you could find yourself running out before mains power is restored. Consider the following points when deciding on the optimal minimum storage capacity of your diesel generator’s fuel tank(s):

Emergency fuel needs

This is the amount of fuel you should allow to compensate for unusually high consumption or a delay is the arrival of new fuel.

Lead time (for re-supply)

This is the amount of time it takes to get new fuel to the generator site from discovering that your supplies are low. It includes purchasing fuel from a vendor, delivery, and actually filling the tank(s).

Lead time (fuel supply)

This is how much fuel you should always retain to keep your generator running non-stop throughout the lead time described above.
That means the minimum amount of diesel fuel you should have on hand is your emergency stock plus your lead time stock.

What will you be using the diesel generator to power?


If you are using your generator as a back-up to the mains supply or to provide small amounts of power for short, discrete time periods you might not absolutely need a large fuel capacity. Selecting lower capacity tanks could mean a lower initial investment and potentially lower maintenance costs. However, you will require more frequent re-fuelling in smaller lots, which will increase the per-litre cost of the fuel and delivery by the vendor. Smaller tanks also limit your flexibility, in terms of your ability to run the generator for extended periods if it ever becomes necessary.

If you are using your generator as a primary power source for a large commercial or industrial establishment, or for almost any purpose where mains power is unreliable or unavailable, you will almost certainly need one or more large capacity fuel tanks. A larger tank allows you to buy fuel less frequently and in larger lots, reducing your ongoing running costs. However, it will cost more to purchase and install the larger tanks, and they will incur slightly more ongoing maintenance expenses. Storing a very large fuel supply may also impose certain safety risks.

What are the 3 main types of generator fuel tanks?

Will you need planning permission to have a fuel tank installed?


The full details can be found here, but under certain conditions a fuel tank is considered ‘permitted development’, if it is within certain limits. That means that it would not require planning permission in most cases.

A tank would be considered permitted development so long as it does not:

  • Hold more than 3500 litres of fuel
  • Stand forward of the principle elevation facing a highway
  • Stand more than 3 metres tall, or 2.5 metres tall if within 2 metres of a property boundary
  • Is not in an area which has heightened planning requirements, such as national parks or Areas of Outstanding Beauty.
  • Is not in an area which has heightened planning requirements, such as national parks or Areas of Outstanding Beauty.

Of course, the devil is in the details, so be sure to check the rules carefully, and consider consulting an expert before making any decisions.
