All members voted in favour except the Onchan MHK
The only MHK to vote against allowing Manx Gas to set its own tariffs and remove a price freeze says he did so because it was in the best interests of his constituents.
In Tynwald this week, Onchan MHK Rob Callister was the sole dissenter against the new regulations which come into force on 1 April.
The new rules will also allow the Communication and Regulatory Authority to cap revenue that Manx Gas earns from regulated activities.
A formal process for tariff reviews and adjustments will also be introduced.
Mr Collister, who is also the chair of Manx Utilities, says he couldn't support the move:
"Substantial progress" made on design of new Castle Rushen High School, says minister
"Demand for green, clean energy is rising amongst all businesses", says MUA
