What is a bunded tank?

A bunded tank consists of a 'tank within a tank'.

The inner tank is the primary storage vessel, whilst the outer tank acts as a failsafe.

In the event of a spill, surplus fuel will safely and securely be stored within the outer tank and an environmental pollution incident will be averted. 

Installation requirements

This Oil Tank must be installed and maintained in accordance to the current OFTEC guidelines, by an OFTEC Registered Technician or similarly competent person.

  • Adequate for the weight of the tank when full
  • Non-combustible, imperforate and level
  • Constructed of concrete, paving stones or stonework
  • Large enough to extend 300mm beyond ALL sides of the tanks

  • Oil Pollution Prevention Guidelines (England & Wales) 2001 PPG26 – Drum and Intermediate Bulk Container Storage

Delivery Information


The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page.  Standard tank deliveries are "kerbside" which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.


Most accessories will be delivered within 1-3 working days. If you require them quicker, we can on occasions offer a next day service (please contact us to discuss). If the item(s) are out of stock we will advise you of the expected lead time and you will of course have the opportunity to cancel with a full refund.

Returns Information

Customers may return items within 14 calendar days (as per our Terms & Conditions) - refer to 4.6 & 4.7. **

Please be aware that returning a tank can be complicated and expensive so please check that you are ordering the correct item (we suggest checking the dimensions very carefully).
