Up to 6,500 homes across the Island could be converted to natural gas this year, if Tynwald approves the move.
A huge operation would see appliances in homes on mains gas inspected by officials to make sure they’ll work on the new fuel.
If the move was made it should mean a reduction in gas bills for consumers.
The project was discussed by Castletown commissioners at a meeting earlier this week, when chairman Alwyn Collister explained the conversion process.
He says all homes could expect a visit to check whether cookers and boilers need changing over.
