What's in the garden?

 What tanks may be a risk  

Best practice  

  • Metal or plastic single skin tanks

  • Tanks over 10 years old

  • Poorly supported tanks

  • Tanks that are poorly located

  • Tanks not fitted to regulations

  • Tanks with signs of bleaching or cracking

  • Metal tanks with signs of rust

Building and environmental regulations

If the tank is near to a drain, bore hole,
river or other water watercourse, and a
pollution incident would occur if the tank
leaked or was overfilled, the chances are
that a bunded tank is needed by law.

  • Integrally bunded (tank within a tank)

  • Top offtake oil supply

  • Contents gauge

  • Overfill prevention device

  • Fitted to building regulations

  • CE marking on plastic tanks

  • Regularly serviced 


Oil tanks should be sited in accordance
with building regulations, which protects
then from a fire that may be started near by.
Siting is typically 1.8m from openings into
building and 760mm from a combustible
boundary. If this can’t be achieved, a fire
barrier can be erected between the tank and hazard.
