A rise in gas prices next month has been announced by Manx Gas.
The 2.9% increase equates to spending an extra 6.5p per day for the average user when coupled with a 3% rise in the standing charge, according to the utility company.
The move is being blamed on mild weather, according to group managing director of parent company International Energy Group Tony Nicholls.
He says, "The business has financially underperformed against the average of the acceptable returns range established in the March 2008 investigation into gas prices.
"This underperformance has been due to below average gas consumption as direct result of warmer than average weather patterns that have been experienced in the Isle of Man."
