Why are oil tanks green?

Posted On: 20 March 2024

Oil Tanks the UK & Ireland are almost always green. There are over a million homes in Great Britain with oil tanks, the majority of which are plastic, some are of the older single skin variety, but many now are bunded (tank within a tank). But why are they green and have been since they became popular as far back as the 1980’s? We asked Dr. Fergal Gribben one of our Senior Engineers if he could shed any light on it, “Yes, it is true that tanks have been manufactured green in colour since the early days, in fact the specific polymer used to manufacture oil tanks itself is a natural white colour.”

“In order to ensure the maximum lifespan of the product, all the materials we use have been designed to meet the rigorous tests outlined in the BS/EN standards that came into force in 2005.  To meet these requirements, every base polymer used in the market is embedded with UV stabilising additives to ensure that the tank is suitable for outdoor conditions in the UK and Ireland.”

“In fact, there are two reasons that oil tanks are green, firstly they have to be coloured to a darker material than the natural powder as this colour helps to block UV light which reduces the potential for microbial growth affecting fuel quality. We at Harlequin use a unique pigment package to ensure that the material maintains its colour throughout its lifetime.”

“The other reason is that out of all the dark colours a dark green was chosen in order to better blend the tank into its new garden environment.” So now every time you seen a green oil tank you will know why its green!
