Fuel Tanks and Bunded Fuel Tanks
Our full range of steel and Polyethylene fuel tanks and bunded fuel tanks are designed for convenient, safe and reliable transport and storage of diesel fuel, petrol, heating oil, biofuels and more.


Fuel Tanks For Safe and Reliable Storage
At National Heater Shops, we know how important the storage and transportation of fuel can be. Whether you’re storing fuel for heating equipment, drying equipment or other machinery, the quality of the fuel tank matters. That’s why we only supply the best fuel tanks from trusted manufacturers, including Sealey, Western Global, Cemo, Dymac and Atlantis Tanks.
Bunded Fuel Tanks For Convenience
Bunded storage units store fuel safely onsite. Some of these units can be connected to equipment directly and used as a primary or auxiliary fuel source. This method is ideal for appliances such as space heaters that do not have an integrated fuel tank. An extra fuel container helps to ensure that equipment can run longer without interruption and without fluctuations in consistency.
Transportable Fuel Tanks
Portable fuel tanks offer a wider range of utility as they can be easily relocated. Smaller single skin tanks, such as Cemo DT-Mobile Easy Refuelling Tanks are ideal for transport. They are suitable for use under the ADR exemption (ADR 1.1.3.1 C), meaning they can be taken to a site in a car, truck or van in order to fuel equipment and machinery. We also have options for oil trolleys, such as the Cemo Diesel Refuelling Trolley, which are equipped with wheels to improve mobility and can be used as a secondary tank.
Fuel Tanks Of Various Sizes
We have a wide range of fuel tanks available in various sizes. These tanks are suitable for spaces such as warehouses, workshops, construction sites, farms, marquees, event companies and more.
Bunded steel tanks are required by law if the tank is over 3,500 litres capacity and in certain environments. For example, if your site is anywhere near a public water source, lake, river, or stream, tanks are essential.
What is a Fuel Tank?
A fuel tank is a storage container that is designed to safely and securely hold fuels such as diesel, kerosene, heating oil, bio fuel, and, in some cases, petrol. Fuel tanks are used across commercial, agricultural, industrial and residential projects and settings to provide a fuel supply for vehicles, generators or heating systems.
What is a Bunded Fuel Tank?
A bunded fuel tank is a double-walled tank featuring an inner tank surrounded by an outer protective tank (the bund). This secondary containment is designed to protect against leaks and spills should the inner tank become damaged, which helps to protect the environment and reduce the risk of contamination.
Fuel Tank FAQs
What fuels can be stored in fuel tanks?
The types of fuel that can be stored in a fuel tank depends on the tank’s specifications. Common fuels include:
Diesel
Heating oil (kerosene)
Gas oil
Biofuel blends
Always make sure to check the manufacturer’s specifications when choosing your fuel tank.
What size fuel tank do I need?
The right fuel tank capacity depends on your fuel consumption, available installation space and delivery frequency. Smaller tanks may suit domestic heating systems, short term use or occasional use, whilst larger capacities are much more useful for farms, construction sites, transport depots and industrial facilities requiring bulk fuel storage.
Where can fuel tanks be installed?
Fuel tanks can be installed in a variety of locations including:
Farms
Commercial premises
Industrial sites
Construction sites
Warehouses
Transport depots
Domestic properties (for heating oil)
Outdoor events and marquees
The installation surface should be stable, level and suitable for supporting the fully loaded weight of the tank.
Are fuel tanks suitable for outdoor use?
Yes, most modern fuel tanks are designed for outdoor installation and are manufactured from durable materials such as polyethylene and steel. As a result, they can withstand year-round weather conditions. Positioning of a fuel tank should still follow manufacturer guidance and applicable regulations.
How long do fuel tanks last?
A quality fuel tank can provide many years of reliable service when properly installed and maintained. Lifespan varies depending on material, environmental conditions, frequency of use and ongoing maintenance.
How do I choose the right fuel tank?
When selecting a fuel tank, the following should be considered:
The type of fuel being stored
Required storage capacity
Available installation space
Whether indoor or outdoor installation is required
Security requirements
Regulatory compliance
Whether a bunded tank is recommended for your application.
Choosing the correct tank ensures safe, efficient and reliable fuel storage for years to come.
