Want to help your heating oil tank last longer?

Whether you need a brand new tank or you just want to give your existing one a little attention, don’t miss these handy tank tips.

Blue Tank Icon

Inspect your tank regularly to prevent leaks

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

Green House Icon

Consider the location of your tank

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

Yellow Sun Icon

Keep an eye out for fading or rust

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

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

The capacity of domestic oil tanks varies from 500 litres 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.
