Mr Asher made several recommendations to the committee, including asking for the Competition Commission to investigate the sector, proposing the introduction of a more open system in the sector and cutting the link between oil and gas prices.
He added that the levels of competition in the market have "been allowed to degrade" in recent times, meaning consumers have been hit with high prices and poor service.
"The starkest manifestation of this is 4.5 million households in fuel poverty and a rise of 43 per cent in the number of consumers coming to energywatch for help," he explained.
"We need to stop this from getting worse, and start taking the steps to make it better."
energywatch released research earlier this week which revealed it is receiving around 49 per cent less contacts from British Gas consumers than it was a year ago.
