Slimline Bunded Oil Tanks

A range of slimline bunded oil tanks from as little as 610mm (2ft) wide. This range of oil tanks is our most popular, ideal for where the access to the installation point is narrow or if general space is an issue. All of our oil tanks are CE Marked and fully comply with current OFTEC regulations.

Basically, a tank within a tank. The inner tank’s job is to store the heating oil, the outer tank’s job is to protect the inner tank and contain any leaks from the inner tank if it should fail to protect the environment.

Domestically, this is dependent on where you live and the regulations in your area. You should check these regulations before making a purchase. However, we would always recommend a bunded tank regardless of your location and its regulations as it is one of the most responsible and safest ways to store your heating oil.  

Hands down, we always recommend a bunded tank as they are the safest and most responsible way to store your heating oil. Single skin tanks, as the name would suggest, only have one skin and if it were to fail for some reason the oil ends up on the ground contaminating the environment. This could lead to loss of your expensive heating oil, no heating and potential fines.  

The base should be strong enough to support the weight of the tank and its contents, bearing in mind that, aproximately, 1 litre of fuel = 1 kg. It should be constructed of non combustible material such as, concrete, paving stones, or stonework.

The tank must be supported across the entire base (no gaps or ridges).

The base should extend the tank by a minimum of 300mm on all sides.

Please visit the OFTEC website of GOV website for more details. 

The prices of a domestic heating oil tank that is bunded, on our website cost from as little as £925+VAT to £1580+VAT.

The answer to this question is very much dependent on what size property you have, how many people live in it and how much space you have available to site the tank (taking the OFTEC regulations into consideration). 

Other things to think about are, how much oil you would like to order at a time, how often do you like to have oil deliveries, do you want to have the option to stock up on oil when the price is low, etc.

All of the plastic tanks that we sell are manufactured using UV stabilised plastic. UV stabiliser is a chemical that is added to the plastic during the manufacturing process. This acts as a kind of sun screen for the plastic, combating deterioration and significantly extending the tank’s service life.  

Slimline Bunded Oil Tanks

Slimline tanks are exactly as the name suggests, slim. From as little as 610mm (2ft) wide they are superb for those hard to reach installation sites. Some are so slim they will even fit through the average doorway.

Other benefits of the slimline tanks include, easy manoverability compared to the wider tanks and narrower foot prints enabeling tank installations in narrow installation sites. Always check with current installation regulations before ordering a tank.
