The Control of Pollution Regulations from 2001 dictate the legal requirements for storing oil (including diesel) on a property. The main points are as such:  


  • Oil must be stored in a container that is strong enough to make sure that it will not burst or leak when full
  • Oil tanks and containers must be placed inside a containment system
  • Valves and pipes must be sealed to prevent leaking and placed within the secondary confinement system or used with a drip tray to catch any spills
  • Fixed tanks must have a sight gauge that has a valve which can be closed automatically
  • Automatic overfill prevention devices must be used when it’s not practical to observe the vent pipe or tank


All of our diesel storage tanks are manufactured to comply with these guidelines. Our diesel tanks are bunded and are made from mild steel or recyclable polyethylene. We also offer multi-compartment diesel tanks to store several kinds of liquids (most commonly diesel and AdBlue).  

What is a bunded diesel tank?

A bunded diesel tank is a bulk diesel storage container comprising of two ‘tanks’. The inner tank contains the diesel whereas the outer tanks contains any spills or leaks from the inner tank. As a legal requirement the outer tank must be able to hold 110% of the contents of the inner tank.

How much should a bund hold?

To comply with oil storage regulations a bund should hold a minimum of 110% of the inner tanks contents. We manufacture steel and plastic bunded diesel tanks.

How do you store diesel fuel?

When bulk storing diesel in quantities above 200 litres a bunded diesel tank is often required. The bunded diesel tanks we manufacture are available in plastic and steel and capacities from 1,350 to 100,000 litres as standard.

How do you store diesel long term?

Storing diesel in a tank below 20°C, out of direct sunlight (especially for polyethylene tanks), and free from water will allow you to store diesel for up to a year without the need for additives. Using additives such as metal de-activators, fungicides, biocides and antioxidants can increase this time.
