Inspect Your Oil Tank Regularly To Prevent Leaks

Check your heating oil tank for corrosion, cracks and splits. These marks could be signs of an impending tank leak.

Green House Icon

Consider the Location of Your Oil Tank

Keep your oil tank on a solid, level surface, far away from buildings and water courses. If any oil gets into the water system, it could cost over £30,000 to clean up. Ouch!

Keep an Eye Out for Fading or Rust

Is your green plastic looking pale? Your oil tank could have been bleached by the sun, making it brittle and prone to cracks. If you have a metal oil tank, make sure to check it for rust and damp patches, too.

Important information: Please note that oil tank installation may not be available at all locations.

The safe storage of heating oil is critical to preventing oil spillages and theft.

To keep things safe, ensure that your heating oil tank is on a solid surface. Check your oil tank regularly for signs of corrosion. An annual professional inspection of your tank will also help you stay on top of any signs of damage or weakening that could lead to a spill.

A lockable lid, security cameras, and security lighting are all handy ways to prevent thieves from targeting your fuel storage area. For more information on oil tank security, read our handy guide to avoiding heating oil theft.

There are several different types and sizes of domestic heating oil tanks. You can choose between single-skin oil tanks, double-skinned, and bunded tanks. Depending on your requirements, you might need a specific type of tank. For instance, you cannot use a single skin tank to store over 2,500 litres. In this case, you’d need a 2,500-litre bunded heating oil tank with both an inner tank and an outer tank to protect against leaks.

You also have a choice of material, from plastic oil tanks to steel. Each of these alternatives has features that cater to specific circumstances, so it’s essential to consult a professional when choosing a new domestic oil tank.

Our team can help you choose the best tank for your needs. Call us at 0345 600 3423 to speak to one of our experts about domestic oil tank types.

There’s no exact rule for how often you need to replace a heating oil tank. Annual tank inspections carried out by OFTEC-registered technicians are the best way to keep an eye on the condition of your tank. Your technician will inform you of any signs of damage or weakening and recommend a replacement oil tank when it’s time.

The capacity of domestic oil tanks varies from 500-litre slimline tanks up to 10,000 litres. However, the average size of a domestic oil tank for UK households is between 1,000 and 2,500 litres. The size of the oil tank you need depends on the size of your property, number of occupants, and available space for the tank. Our expert team can help you choose the right tank size for you.

Heating oil evaporation is possible in very high temperatures, for example, during a heatwave. However, as these extremely high temperatures are rare in the UK, you are unlikely to lose a substantial amount of oil through evaporation.
