We will consult with you over the size and whether a below ground or above ground tank is best. For domestic purposes the tank size will usually be below 3500 litres. This is important as there are further regulations for fuel tanks over this size.

In most instances we will need to also install a concrete base on which to sit the tank. When full, the oil tank will be extremely heavy. Consequently, without sufficient base support it will slowly sink into the ground below and become hazardous. The oil tanks we install will last in the region of 15-25 years.

Common types of heating oil tank we install

Tankology can install a myriad of heating oil tanks for both domestic and commercial applications. Typically, there are two types of tank for storing heating oil. Both of these tanks can be installed above-ground or buried below-ground. OFTEC guidelines mean only integrally bunded tanks can be installed in Wales.

Integrally bunded heating oil tanks

Bunded tanks have an additional outer tank layer. This is called a bund and is a safety measure for better containment. Additionally, the bund will also provide protection from exposure to the elements.

Single skinned heating oil tanks

These can be plastic (usually green) or metal. Typical single skinned tanks do not have a protective bund. As a result they are the cheaper option of the two, but are subject to much tighter Government regulations.

Frequently asked questions

There are safeguarding regulations in place that dictate how close to a building you can install a heating oil tank. For tanks with a capacity of less than 3,500 litres they must be installed a minimum of 1.8 metres from a non-fire-rated wall. In some instances you can refer to guidelines set out in the British Standard BS5410.

It’s good practice not to install a fuel tank of any kind inside a building. This includes heating oil tanks. That said, you can have an internal oil storage tank, but even then it should not be installed in a habitable area, whether domestic or commercial.

In short, Tankology prefer bunded tanks because they are more durable and more secure for the environment. There may be times when a single skinned tank will be the only option, but that is rare. You also need to carry out an oil storage risk assessment.

Whilst not as popular a overground fuel storage tanks, underground or buried tanks are available. These can be buried on your property with the top accessible for filling. You may consider this a viable option if you are short on space or want to keep an unspoilt view.

Whilst there are no laws restricting you from installing the tank yourself, we would advise you don’t. For safety reasons we would always advise you to employ a professional engineer with experience in this area. Furthermore, it’s best to use an OFTEC registered tradesman or company.
