1200 Litre Slimline Plastic Bunded Oil Tank – Black

This 1200 litre slimline plastic bunded oil tank is designed for properties where space may be limited but reliable heating oil storage is still essential. Its narrow profile allows the tank to be positioned more easily alongside buildings, in side passages, or on compact bases where wider tanks may be difficult to install.

With durable polymer construction and integrated secondary containment, the tank offers dependable storage for kerosene heating systems while maintaining a neat and discreet installation.

What Is a Slimline Bunded Oil Tank?

A slimline bunded oil tank stores heating oil within a double-layer design created to improve safety and environmental protection. The inner tank holds the fuel while the outer bund forms secondary containment designed to capture potential leaks or spills.

This style of tank is commonly selected where a slimline oil tank for narrow access is required, allowing heating oil storage to be installed in locations where wider tanks may not fit comfortably.

Construction and Design

The tank is rotationally moulded from Medium Density Polyethylene (MDPE), a durable polymer widely used in oil storage because it resists corrosion and outdoor weather exposure.

This construction forms a strong plastic oil storage tank with an outer bund that surrounds the internal tank for additional protection. The black finish helps create a discreet installation, allowing the tank to blend naturally into garden areas, service spaces, or side passages.

Installation and Safety Considerations

The slimline design allows this tank to be positioned in locations where installation space may be restricted. With a footprint of 880 mm width and 1880 mm length, it can be installed more easily on smaller bases or within narrow access areas.

The integrated bund provides built-in spill containment designed to help reduce environmental risk. A locking cap also helps protect stored fuel from tampering or unauthorised access.

Installation should be carried out on a suitable non-combustible base that extends beyond the tank footprint, with appropriate clearances maintained from nearby buildings, boundaries, and ignition sources. Using an OFTEC-registered installer helps ensure the installation meets recommended guidance.

Capacity and Usage

With a storage capacity of 1,200 litres, this tank provides practical fuel storage for many domestic heating oil systems.

A 1200 litre oil tank is often selected for homes with moderate heating oil consumption, offering dependable storage capacity while still maintaining a manageable installation footprint.

Durability and Longevity

The UV-stabilised MDPE construction helps protect the tank from corrosion, weather exposure, and UV degradation when installed outdoors. Unlike steel tanks, polymer tanks do not rust and require minimal maintenance over time.

The integrated bund provides an additional layer of protection against spills while supporting long-term reliability. A 12-year manufacturer warranty (terms apply) provides additional reassurance for homeowners investing in dependable heating oil storage.
