Oil Storage Tank Regulations Ireland

Taken from the Dept of Environment leaflet-


Note 1 . An oil storage tank not exceeding 2500 litres capacity which serves a dwelling house does not require a bund. An oil
storage tank which is not provided with a bund should be installed on or above a non combustible base which extends out at
least 300 mm from all sides of the tank.

A bund is a cavity to catch leakages. - Must be able to hold all of tank contents.

I might be able to put it beside the garage - the wall is concrete so no danger of fire there. Not sure about the overhanging guttering though?
