Frequently Asked Questions

1. Do I need a bunded steel oil tank?
   Yes, mostly. UK regulations require bunded tanks for environmental protection, especially near watercourses or drains. However, current regulations still permit single skin steel oil tanks in England. A bunded tank is a tank within a tank, the outer tank provides protection for the inner tank which therefore makes it harder for the inner tank to fail.  However, in the unlikely event of the inner tank failing, the outer tank will provide secondary containment.
   In this 1250 litre steel bunded oil tank, the liquid is stored in the primary or inner tank and the outer tank forms the required bund with capacity for 110% of the primary tank’s capacity which makes this tank suitable for both domestic and commercial installations. 
2. How long will this tank last?
   Your steel bunded oil tank is covered by a solid Atlantis 10-year warranty subject to regular maintenance and warranty registration. In reality, it should last 20 years or more with frequent upkeep, checking for rust spots etc.  
3. How quickly can I get this tank?
   We deliver direct to site with a 98% success rate, using our own fleet and HIAB trucks. Atlantis dispatches most orders within 2-5 days.
