So you find yourself having to replace your old heating oil tank. Chances are, it is a single skin tank, meaning that it is a typical, single layered hollow model. For that reason, chances are also that you are replacing your tank because it split!

Until recent years, most heating oil tanks were single skin models and many were made of steel, rather than the more commonly seen plastic versions we have today. The problem with both steel and single skin plastic models is that they are much more likely to split or suffer weather damage and therefore pose an environmental risk. cost to replace oil tank

The Control of Pollution (Oil Storage) Regulations came into effect in the UK in March 2011. The regulations state that a secondary containment system (a bund) must be incorporated at all relevant oil tank installations, where storage requirements exceed 200 litres. All new tank installations are required by law to comply with the regulations by 20th September 2011.

So what exactly is a bund?

A bund is a secondary containment system. When the term is applied to a heating oil tank, it means that it consists of a tank within a tank design. The inner tank acts as your primary oil storage container, while the outer acts as a protective layer and is capable of containing oil in the event of the inner layer being damaged or splitting. This prevents the oil from leaking into its surrounding environment and ensures that it does not contaminate nearby water supplies or landscapes.
