What is a double skinned oil tank?

A double skinned oil tank is specifically designed for the storage of heating oil. Unlike a single skinned tank, which has only one layer of protection, a double skinned oil tank has two layers, with the inner tank surrounded by a secondary, protective outer tank. This double layer of protection helps to prevent leaks and spills, making double skinned oil tanks a safer option for the storage of heating oil.


Is there a difference between double skinned oil tank and bunded oil tanks?

No, these terms are often used interchangeably.


Are double skinned oil tanks safer than single skinned tanks?

Double skinned oil tanks are considered safer than single skinned tanks because they offer a double layer of protection against leaks and spills. In the event that the inner tank begins to leak, the outer tank will contain the leak. This reduces the risk of contamination or loss of expensive heating oil. Additionally, the double skinned design makes it easier to detect and address any issues with the inner tank, as the outer tank provides a visual indication of any changes in the level of heating oil.


What are the regulations regarding double skinned oil tanks in the UK?

In the UK, double skinned oil tanks must comply with regulations set forth by the Oil Firing Technical Association (OFTEC). These regulations cover a wide range of aspects, including the design and construction of the tanks, the materials used to make the tanks, the installation process, and the ongoing maintenance and safety requirements for the tanks.

OFTEC sets the standards for the design and manufacture of double skinned oil tanks to ensure that they meet the highest safety and quality standards. At SG Tanks, all of the oil tanks we offer adhere to OFTC regulations.


How do I maintain a double skinned oil tank to ensure its safety and longevity?

To ensure the safety and longevity of your double skinned oil tank, it is important to maintain it properly. Here are some key steps you can take to maintain your tank:

  • Regular inspections – regularly inspect your tank for any signs of leaks or damage, such as cracks or dents in the outer tank.
  • Cleaning – keep the area around your tank free from debris and any other potential ignition sources, and regularly clean the tank to prevent a build-up of dirt or debris.
  • Proper installation – make sure that the tank is installed properly and level, to prevent any leaks or spills.
  • Tank protection – if necessary, consider installing a secondary containment system, such as a bund, to further protect your tank from leaks and spills.
  • Ongoing maintenance – schedule regular maintenance checks with a qualified professional to ensure that your tank is in good condition and functioning properly.


What is the lifespan of a double skinned oil tank?

The lifespan of a double skinned oil tank can vary depending on a number of factors, including the quality of the materials used, the frequency and quality of maintenance, and the environmental conditions in which the tank is stored. However, on average, a well-maintained double skinned oil tank can last between 20 and 30 years.

To extend the lifespan of your double skinned oil tank, it is important to follow the maintenance and care instructions provided by the manufacturer and to schedule regular maintenance checks with a qualified professional such as SG Tanks.

I used SG Tank installations in April 2022 to replace my Oil Tank that was starting to show cracks. They were responsive, well-priced, and a pleasure to deal with on site. I will be using them again for any future needs.

We used SG Tanks and SO happy with the whole process. We had contacted for a quote via their website and was contacted very quickly to book in a survey - They turned up at the time booked and the quote arrived the same day as the survey. Once I gave them the go-ahead the work was booked in and completed withoin four days of the initial enquiry. The installers were polite, explained everything that was going on and did a really a really tidy job. Can highly recommend SG Tanks.
