Manx Gas customers will be hit with a 3.5 per cent price rise from the end of next week.
Standing charges are due to go up by the same percentage, too.
It means the average bill will go up by around £27 a year.
The firm's commercial director, John Davies, says it can no longer absorb rising global energy costs:
