It said the sector currently spent almost £5.3 billion a year on oil for its heating, lighting and manufacturing processes.
Unsurprisingly, it has advocated the use of lpg: "Even though oil prices are currently falling, new research suggests this figure can still be cut dramatically to around £3.85 billion by switching to lpg."
Flogas MD Lee Gannon (pictured) said: "We initially carried out the research purely for internal purposes, but after seeing the figures, we felt the only responsible action was to share them with the industry. These are figures that everyone needs to see.
"Times are still tough, and there is a greater need than ever for businesses to reduce their energy costs and cut carbon emissions."
