Gas bills for Island residents will be brought up by politicians in the House of Keys this week.
Douglas Central MHK Chris Thomas will question Chairman of the Office of Fair Trading, Martyn Perkins MHK, on the matter when the house reconvenes for its next sitting.
Mr Thomas wants to know what the average household gas bill is in Manx shores and how the OFT carries out its functions to protect consumers.
The latest Keys session will take place in Douglas tomorrow from 10am.
