Download the OFTEC Home Guide for oil storage tanks that gives advice for the storage of home heating oil tanks up to 3500 litres capacity supplying oil to single family dwellings for heating and cooking purposes.
Depending on where you live, regulations may vary slightly. The information in this guide is a general guide, and you should check with your nearest OFTEC Registered Technician which regulations affect you.
For non-domestic oil storage, please follow the guide below:
Safe oil storage
It’s very unlikely that a fire could be started by the contents of an oil storage tank. However, it does need to be protected from a fire that may originate nearby. Non-domestic tanks below 3,500 litres should be sited 2m away from any buildings or boundaries. If it’s impossible to comply with this requirement, then a fire barrier rated of at least 60 minutes should be provided, extending 900mm higher and wider than both ends of the tank.
Non-domestic tanks above 3,500 litres should be sited 6m away from any buildings or boundaries. If it’s impossible to comply with this requirement, then a fire barrier rated of at least 120 minutes should be provided, extending 900mm higher and wider than both ends of the tank.
It’s important that oil storage tanks are inspected annually, preferably by an OFTEC Registered Technician.
Proper support is vital for your tank, which will be very heavy once it’s full of oil. Steel tanks can be supported off the ground by purpose built masonry piers, or may be supplied with steel supports. Plastic tanks can be supported by a purpose built raised platform on masonry piers, or alternatively can be installed at ground level.
All oil storage tanks must be supported adequately by a non-combustible, level base.
Internal Oil Storage
In some situations, the oil storage tank can be sited inside a building. For those installations, the tank must be self contained within a fire resistant chamber. Any tank above 3,500 litres should be placed on the lowest level of the building. Your OFTEC Registered Technician will be able to advise on the different types of internal oil storage.
Non-domestic oil storage tank installations must comply with regional environmental requirements and relevant British Standards. Your OFTEC Registered Technician can advise you on this.
