We supply and install Harlequin and Kingspan Titan bunded oil tanks.  The bunded oil tanks carry a 10 year guarantee. 

Harlequin 1200 Low Profile Bunded Oil Tank

Harlequin 1200 Low Profile Bunded Oil Tank

The Harlequin range of plastic ‘Bunded Oil Tanks’ are suitable for storage of heating oil for a variety of domestic applications.

A bunded heating oil tank simply consists of a tank within a tank. Heating oil is stored in the inner tank and the outer tank acts as a fail safe so that in the event of a spillage, excess fuel will collect in the outer tank. The bunded design helps avert pollution incidents should there be a leak and the hassle of costly environmental clean-up operations.  Bunded oil tanks have been proven to significantly reduce the risk of pollution. They are a requirement at most domestic and commercial premises in the United Kingdom and Ireland.
