Islanders in Sark could see electricity prices plummet, after politicians voted for a regulator.
Chief Pleas voted for the a regulator for the first time last night, who will be able to check prices.
The island currently pays the highest price in the islands for electricity, around four times more than Jersey.
David Gordon-Brown, the manager of Sark Electricity, says the recommendation by the island's first electricity regular to reduce electricity prices tells "a story of betrayal".
The amount islanders pay for electricity should be cut, according to Sark's Electricity Commissioner.
Currently electricity in Sark is set at one of the highest prices in western Europe at more than 60p per unit.
Sark's government says a new electricity regulator is a 'step forward'. They can regulate prices which are among the highest in the world.
