Not every home heating oil tank legally has to be bunded, but in many cases it’s the safest and most responsible choice. Whether you’re installing a new tank or replacing an old one, factors like your tank’s location, size, and proximity to water sources can influence whether bunding is recommended or required.
When a Bunded Tank Makes Sense
In Scotland, bunding is legally required for tanks in higher-risk situations, including:
-
Near drains or built-up areas where a leak could affect neighbours’ gardens or streets.
-
Close to rivers, ponds, or wells, where even a small spill could contaminate water.
-
Tanks serving multiple households or shared buildings such as flats or holiday homes.
-
Areas with vulnerable groundwater or other environmental sensitivities.
-
Sloped or flood-prone sites where spilled oil could flow into drains or open land.
For domestic tanks under 2,500 litres in lower-risk locations, bunding may not be legally required but is highly recommended to protect your home and the environment.
Using a bunded tank provides extra protection against leaks, reduces environmental risks, and ensures compliance with Scottish regulations where applicable
What Is a Bunded Tank?
A bunded tank is essentially a tank within a tank. The fuel sits in the inner tank, while the outer bund acts as a secondary barrier. It’s designed to hold 110% of the inner tank’s capacity, so if the inner tank leaks, the fuel remains safely contained.
Benefits of Bunded Tanks
- Protects the environment: Minimises the risk of spills reaching soil and water.
- Safety first: Reduces the chance of fuel escaping if the tank is damaged.
- Cost protection: Helps avoid fines or expensive clean-up costs in the event of a leak.
- Extra reassurance: Many manufacturers offer long warranties if installed by an OFTEC-accredited engineer.
Even if your property doesn’t legally require a bunded tank, it’s often the safest and most reliable option. At Oilfast, all our tanks come with 10-year manufacturer guarantees and British Kitemark approval, giving you peace of mind while protecting your home.
