If the oil tank has a nominal capacity of less than 3,500 litres, it should not be placed any closer than 760 mm to a boundary. This assumes that there are no flue outlets or buildings between the tank and the boundary.

Oil tanks with a nominal capacity of less than 3,500 litres should not be placed within 1.8 metres of a flue outlet.

Oil tanks with a nominal capacity not exceeding 3,500 litres should not be fitted any closer than 1.8 metres to a non fire-rated (30-minute minimum fire resistance) wall or eaves.

Internal oil storage tanks should never be installed in a habitable area and if installed internally, should always be contained within an enclosed chamber or bund, and the area must be adequately vented.
