Positioning Your Bunded Oil Tank | Tanks For Everything

A bunded oil tank is the safest way to store oil at a home or business. Of course, you have to make sure that the tank is installed and maintained in a safe manner, in much the same that way you do with other additions to your property, such as boilers or other heating system components.

Oil storage regulations for businesses - GOV.UK

How to store oil, design standards for tanks and containers, where to locate and how to protect them, and capacity of bunds and drip trays.

Why do you need to bund a tank?

The new requirement was put in place because Bunded Tanks offer more environmental protection than single-skins (tanks without a bund) and are by far the safest way to store fuel.

How long does a bunded tank last?

What is a bunded tank?

A Bunded tank is essentially a tank within a tank. The oil is held in the inner tank or ‘skin’ and the outer-skin is a secondary tank that offers protection. This bund must be able to take the contents of the inner tank plus 10 % so in other words 110% of the tanks capacity in order to comply.

What are the benefits of bunds?

What Are The Benefits of Bunded Tanks? Bunded tanks offer added protection against contamination, leakages, and oil replacement, making them the safest way to store fuel. If the inner-skin cracks, the bund will retain the fuel and it can be reused, preventing environmental damage to the surrounding area.

2. Longer warranty

While single skin tanks are significantly cheaper than bunded oil tanks, they also have much shorter warranties. Generally a bunded oil tank will have a 10-year warranty, while a single skin tank will have just a two-year warranty.

3. Avoiding environmental damage

Oil is one of the most common causes of pollution – accounting for 15% of pollution incidents every year. Oil spillages can be devastating to the local environment – from polluting waterways to destroying natural habitats and killing trees with preservation orders.

4. Cost of an environmental clean-up

Most insurance companies won’t cover a policy holder for an oil spill. With no built-in protection from oil leaks in a single skin tank, a leak is far more likely and would more than cancel out any savings made in buying a cheaper single skin tank.

5. Additional safety features

With domestic heating oil tanks capable of holding well over £1,000 worth of kerosene, it’s not surprising that oil tanks are a target for thieves. To make matters, heating oil theft can also lead to spillages, a difficult phone call to the Environment Agency and the possibility of big clean-up fees.

7. Oil can be reused if you have a leak

If a bunded oil tank leaks, the oil is captured in the second skin. Not only does this prevent environmental damage and a costly environmental clean-up, it also means you don’t lose the oil and can reuse it.

8. Protection against rainwater

Bunded oil tanks are carefully designed to prevent rainwater entering the tank. Water can cause a lot of damage, but it can be difficult to tell if you have water in your heating oil tank until something goes wrong with either your boiler or AGA, which ends up with an expensive call-out when there is a problem.

9. Cost savings

The price of kerosene fluctuates dramatically throughout the year, so it makes sense to buy in bulk when the price is low, which is far easier to do if you have the biggest oil tank you can at your home – and of course a tank over 2,500 litres must be bunded.
